Abstract Technology has changed the nature of gambling practices over the last decade and is
continuing to do so. The online sports betting industry has become a rapidly growing sector of
the global economy, with online sports betting contributing 37% of the annual online gambling
market in Europe. There has been an integration of social and technological processes that has
enabled the cultural saliency of contemporary online betting. One of the more newly introduced
forms of online sports betting is in-play sports betting behaviour (the betting on events within a
sporting event such as football and cricket). In-play sports betting features (such as ‘cash out’)
are increasing in popularity amongst online gambling operators. A scoping study was carried
out examining the evolution of this new form of gambling practice which included both a
systematic literature review and the examination of 338 online gambling websites that offered
sports betting. The present study identified a comprehensive list of what in-play betting features
are currently being offered on online gambling websites as well as other information concerning
in-play sports betting. A total of 16 academic papers and two ‘grey literature’reports and were
identified in the systematic review. Out of 338 online gambling websites that were visited, 26%
of these offered at least on in-play betting feature. Results from the systematic review suggest
that in-play sports betting has the potential to be more harmful than other ways of gambling
because of the inherent structural characteristics.

The popularity of online gambling has markedly increased over the past decade, and it has
been predicted that it will continue to grow in the coming years (Gray et al., 2012). Sports
betting via the use of online platforms has already grown in popularity as a form of gambling

in numerous countries around the world (Lopez-Gonzalez and Griffiths 2016a), and betting
with online sports bookmakers comprises 37% of the annual online gambling market in
Europe (European Gaming & Betting Association 2016). The value of remote betting (which
includes betting online via PC, laptop, tablet, smartphone, television, etc.) has seen a substan-
tial increase in recent years, with football betting and ‘in-play’betting being a predominant
driver of growth (Lopez-Gonzalez and Griffiths 2016a). In-play betting, also known as ‘live
action’betting or ‘in-running’betting, refers to the wagering on an event that has started but
not yet finished. Here, gamblers have the option to continue to bet once an event has started,
and adapt their bets depending on how the event is progressing (e.g., on a sporting event such
as a football or cricket match).
In-play betting first appeared towards the end of the 1990s when some bookmakers would
take bets over the telephone whilst a sports event was in progress, and has now evolved into a
popular online service in many countries (Odds Checker 2017). For example, in the UK, up to
25% of online gamblers have placed a bet in-play (Gambling Commission 2016). The online
sports betting company Bet365 reported that 80% of all their sports betting revenue is derived
from in-play bets alone (Jackson 2015). The introduction of in-play betting has allowed
bookmakers to increase the number of markets available to bet on during sports events, and
gamblers are able to place bets based on many different types of in-game activity during the
matches. For example, in football matches, it is possible to bet in on in-play markets including
the match result, half-time score, number of goals scored in the first or second half of the game,
the number of yellow cards during the match, and the name of the goal scorers. The availability
of a particular sport and in-play markets varies from bookmaker to bookmaker.
Researchers have previously referred to the role of structural characteristics in the acqui-
sition, maintenance, and development of online gambling behaviours (Parke and Griffiths
2007). Structural characteristics are those features that are inherent within the game itself and
include features that are responsible for reinforcement and may in some cases facilitate
excessive gambling (Griffiths et al. 2006). These characteristics include, but are not limited
to, bet frequency (the number of bets placed within a given time frame), event frequency (the
number of gambling events that are available to bet on in a given period), and pay-out
frequency (the time between the end of the betting event and receiving the winning payment)
(Griffiths and Auer 2013).
In-play sports betting has structural characteristics that have changed the mechanics of
gambling for sports bettors, as they are now able to place a larger number of bets during a
single sports game (as opposed to a single bet on who is going to win). It has been argued that
structural characteristics of an event, including higher event frequency betting, are associated
with problem gambling (Griffiths and Auer 2013; Harris and Griffiths 2017). One of the most
important differences between being able to place an in-running sports bet opposed to a pre-
match bet is that the nature of the market has been turned what was previously a discontinuous
form of gambling into a continuous one (Griffiths 2012; Griffiths and Auer 2013). The
gambling study literature has suggested that in-play sports betting may offer more of a risk
to problem gamblers because it allows the option for high-speed continuous betting and
requires rapid and impulsive decisions in the absence of time for reflection (Hing et al.
2014a,b,c;Lopez-Gonzalezetal.,2017a,b,c,d;Nelsonetal.2008). Furthermore, marketing
messages promoting online sports gambling have been become increasingly prevalent to
media audiences (Lopez-Gonzalez and Griffiths 2016b).
Sports betting is one of the most commonly promoted forms of gambling in many countries,
and access to this marketing activity has been associated with sports betting problems (Hing

et al. 2016; Lopez-Gonzalez et al. 2017a). Advertisements often promote online sports betting
as being easily accessible, anywhere at any time, using a mobile or other internet compatible
device (Hing et al., 2017a,b;Lopez-Gonzalezetal.2017a). There has also been a growth in in-
play sports betting advertising. For example, within a sample of British and Spanish sports
betting advertisements, in-play betting was prevalent in just under half of the adverts (Lopez-
Gonzalez et al., 2017a,b,c,d). One popular form of gambling advertising is the promotion of
wagering inducements. These are often inducements that are promoted during a live event, and
it has been suggested that doing so may promote impulse betting, where those placing a bet
have an immediate chance to place the incentivised bet via a platform (Lamont et al. 2016).
Inducements promoted during an in-match sporting event have been cited as a practice that may
encourage in-play impulse betting intentions (Lamont et al. 2016).
Gambling companies have been known to promote mobile betting over other forms of
gambling in their advertisements (Lopez-Gonzalez et al., 2017a,b,c,d) by overstating the
illusion of control that gamblers perceive when placing bets via their smartphones (Lopez-
Gonzalez et al. 2017b). A main cognitive heuristic involved in the maintenance of gambling
behaviour is the illusion of control (Langer 1975;Griffiths1994). The illusion of control
generates an expectency of success that is inappropriately higher than is objectively warranted
(Langer 1975). In-play sports has the potential to enhance the illusion of control because
gamblers are often able to dictate the speed of play, the volume of betting, and amount of
money wagered, which may enhance both psychological perception and investments of control
over their sports bet placement.
Whilst in-play sports betting features (such as the ‘cash out’feature) are increasing in
popularity amongst online gambling operators (Lopez-Gonzalez and Griffiths 2016b)and
despite the growing body of research investigating the psychosocial and individual psycho-
logical factors determining gambling behaviour, much less attention has been devoted to
understanding these factors in the context of in-play sports betting and the market character-
istics of online sports betting. Therefore, the goal of the present scoping study was to identify
what (i) has been published on the topic, (ii) empirical studies have been carried out, and (iii)
in-play features are currently available to online sports gamblers via an examination of the
world’s leading sports betting sites.
Method
Design and Materials
A scoping study was carried out to investigate in-play sports betting. According to Mays,
Roberts and Popay (2001), a scoping study aims to Bmap rapidly the key concepts underpin-
ning a research area and the main sources and types of evidence available, and can be
undertaken as stand-alone projects in their own right, especially where an area is complex or
has not been reviewed comprehensively before^(p.194). A scoping review differs from
traditional literature reviews in that it is a preliminary assessment of the potential size and
scope of the available research literature and there is no attempt to control for the quality of the
data or where it was obtained (Kavanagh et al. 2005). Scoping reviews also tend to address
broader topics where many different study designs might be applicable, rather than focusing on
a well-defined research question. They may also include information from non-academic
sources (e.g., information available on websites).

The current scoping study was carried out by (i) examining in-play sports betting literature
(both academic and the non-academic ‘grey’literature) and (ii) accessing and examining
information obtained from online gambling websites that feature in-play betting facilities
and features. As far as the authors are aware, the present paper is the first to examine
availability of literature relating to online in-play sports betting and its specific features on
online platforms. The scoping study focused on the following questions: (i) What in-play
betting features have been made available to online sports betting users? (ii) What empirical
research has been carried out on in-play sports betting? (iii) What has been theorised or
speculated upon concerning in-play betting in the gambling studies literature?
Procedure
A comprehensive research strategy was adopted that involved searching for evidence from
electronic databases: Scopus, Web of Science,PsycARTICLES,PsychINFO PubMED,
ProQuest Dissertation and Thesis Global and Google Scholar. To identify any literature
related to in-play betting, the follow search terms were used: BIn-play [AND] betting^,BLive
[AND] action [AND] betting^,BOnline [AND] sports [AND] betting^,BIn-running [AND]
betting^,BIn-play [AND] gambling^,BLive [AND] action [AND] gambling^,BOnline [AND]
sports [AND] gambling^,BIn-running [AND] gambling^,BInternet [AND] sports [AND]
gambling^and Binternet [AND] sports [AND] betting^. The studies were selected if they
contained the following criteria: (i) being published in English and (ii) including any infor-
mation (e.g., theoretical critique) or empirical data pertaining to in-play sports betting.
Furthermore, reference lists of retrieved studies were also searched to identify any additional
relevant studies. A flow diagram demonstrating this process is shown in Appendix Fig. 1.
Academic papers and grey literature were examined to identify any information relating to
in-play sports betting. After ‘scoping’the literature, a list of any academic papers (both
empirical and theoretical) relating to in-play sports betting were identified and are described
within the results section. Internet gambling websites were visited to see what features were
currently available for in-play sports betting users. A list of 514 online bookmakers that offered
online sports betting services was retrieved from the Top 100 Bookmakers (2017)website
(http://www.top100bookmakers.com/completelist.php). The gambling websites visited were
included for review if (i) they offered an online sports betting service, and (ii) it was possible
to access the website in English. This resulted in a total of 338 online gambling websites from
around the world being visited and reviewed. Those that offered in-play betting services were
examined in further detail and are listed in Appendix Table 3(n= 88). Different features from
each of the websites were reviewed, including ‘help and support areas’,‘terms and conditions’
and ‘promotions’. These were examined to understand what in-play sports betting products, if
any, were available for that website. After ‘scoping’the websites, a list of in-play sports betting
features were coded and are described in the results section and in Appendix Table 3.
Results and Preliminary Discussion
In-Play Literature
After conducting a systematic literature search, 2047 papers were identified. Once duplicate
articles had been removed using Mendeley software and manual searching, 438 papers

remained. Of these, 16 papers were identified which included empirical data or theorised about
in-play sports betting in the gambling study literature. Thirteen of the papers were empirical,
and three of the papers were theoretical and/or commentary based providing some kind of
critique of in-play sports betting (see Table 1).
Behavioural Tracking Data
Prior to 2006, online gambling studies were predominantly based on self-reported
methods and data (Griffiths et al. 2006). Since then, a number of studies have utilised
behavioural tracking datasets provided by gaming operators (Griffiths 2014). Datasets
provided by bwin have resulted in a series of empirical contributions regarding actual
online gambling behaviour (Braverman and Shaffer 2010; Braverman et al. 2013;Gray
et al., 2012;LaBrieetal.2007;LaPlanteetal.2008;Nelsonetal.2008;Xuanand
Shaffer 2009). Using a dataset of nearly 47,000 European gamblers, analyses have been
conducted using two main approaches: (i) general behaviour descriptions of people who
used one particular type of gambling product and (ii) behavioural data pertaining to
account closures and the use of online responsible gambling features. In-play sports
betting is one form of online gambling which has been examined in relation to its
association with problem gambling. The remainder of this section looks at the main
findings of these studies.
LaBrie et al. (2007) published the first research on actual gambling behaviour using the
bwin data sample. This was a longitudinal study of sports gambling behaviour consisting
of sample of 40,499 subscribers, studied over an 8-month period. The aim of the study was
to describe Internet gambling behaviour, which was determined by analysing three vari-
ables converted to measure gambling involvement: number of daily bets, money bet, and
money won. They found that within a sample of online sports bettors, in-play sports
bettors (as opposed to those classified as fixed-odds gamblers who placed their bets prior
to sports event starting) were more likely to be categorised as heavily involved gamblers
(based on number of bets, amount wagers and net losses) when compared to fixed-odds
gamblers. One limitation of this study is that this betting behaviour may not have been
representative of the participant’s total online gambling behaviour (e.g., bettors may play
on other online sites or in betting shops). It was also noted that players other than the
account holder may have bet using the online account (LaBrie et al. 2007). Finally, LaBrie
et al. (2007) suggest that the progression of activities that lead to pathological gambling
may require longer exposure to Internet gambling than the 8 months of gambling that were
observed during their study.
LaPlante et al. (2008) reported that within a sample of 47,603 bwin subscribers, there
was a decline in population participation, number of bets, and size of stakes during an 18-
month period. However, this pattern was not seen amongst a sub-group of heavily
involved bettors, particularly for in-play sports bettors. Those that placed bets in-play
were found to maintain high levels of betting in the period following on from the initial
subscription. Several limitations of the study were noted. For example, it was not possible
to determine whether the sample utilised other online gambling activities as well as sports
betting outside of the bwin website. It is possible that the decrease in gambling activity
may have been because bettors moved their betting activity to a different gambling service
provider. If this was the case, then it is noted that the overall gambling activity would have
been underestimated.

The paper argued that structural characteristics, including
event frequency, appear to be a contributing factor in
problem gambling. It was argued that in-play betting had
changed the structural characteristics of sports betting from
one that was typically discontinuous (e.g., a weekly bet on
the outcome of a football game) to a ‘continuous’form of
gambling with an increased event frequency that is associ-
ated with problem gambling.
Hing et al. (2016) Self-report 639 The risk of experiencing gambling-related problems was
associated with a higher number of bets being placed in--
play, before an event has started; and on impulse before or
during a match.
Hing et al. 2017a) Self-report 1816 Impulsive sports bettors (characterised as having higher trait
impulsiveness, more frequent sports betting behaviour,
higher problem gambling severity and a shorter history of
sports betting) were more likely to bet on in-play sporting
events than overall match outcomes.

opposed to those who bet before matches) were categorised
more often as heavily involved gamblers.

Behavioural Markers for At-Risk Gambling
Studies using the bwin dataset have also aimed to identify problem gambling in its early stages.
When players surpass what is considered a normal level of gambling activity, they may be
categorised at risk of developing gambling problems or already engaged in too much gam-
bling. Some research has utilised behavioural tracking data in an attempt to identify such
thresholds with the aim of detecting markers for problem gambling at the earliest opportunity.
Braverman and Shaffer (2010) examined whether several gambling characteristics could
serve as predictors of future gambling-related problems using a sample of 530 in-play sports
bettors who went on to close their accounts due to gambling-related problems after a 1-month
period. Four characteristics were considered when gamblers initially started betting: (i)

It was theorised that the in-play ‘cash-out’feature has struc-

Self-report 659 Problem gambling severity was positively associated with (i)
how much gamblers talked about betting with other people
prior to bet placement and (ii) how often online betting
functions such as ‘cash out’were utilised and time spent
betting. In-play sports betting was found to be more prev-
alent amongst problem gamblers when compared to
moderate-risk gamblers, low-risk gambler and non-problem
gamblers.

567 Bettors who utilised a self-limit (SL) feature were more likely
to prefer in-play betting on match outcomes opposed to
betting on fixed-odds events. Bettors who used the SL
feature placed more bets per day but wagered less money
per bet on in-play betting than non-SL players. After
utilising the SL feature, subscribers reduced gambling ac-
tivity. However, for sports-betting gamblers, the frequency,
amount and percentage-loss of wagers did not change.

It was theorised that because of the change in structural
characteristics that in-play gambling provided that in-play
betting may contribute to problem gambling because of (i)

events more interesting and/or exciting.

226 Prior to closing their gambling accounts, self-identified in-play
betting problem gamblers, whilst experiencing increasing
losses, were more likely to try to recoup their losses by
increasing their stake per bets on events that had less risky
(i.e., shorter) odds. A decrease in gambling frequency
in-play problem bettors was observed prior to account
closure.

gambling frequency (number of betting days), (ii) gambling intensity (number of bets per day),
(iii) gambling trajectory (the tendency to increase or decrease the amount of wagered money)
and (iv) gambling variability (the standard deviation of wagers). They found that gamblers
who were more likely to close their online betting account due to gambling-related problems
initially demonstrated a higher pattern of high variability, high intensity, and high variability of
wager sizes when in-play gambling than the gamblers who did not report gambling-related
problems upon closing their account. Although it is not possible to determine why there was a
relationship between high wager intensity and variability and gambling-related problems, it
was speculated that external factors (e.g., availability of time, social relationships, or money
resources) influence problem gamblers more than ‘social gamblers’. Furthermore, the vari-
ability in in-play wagers may be indicative of gamblers’desire to stop or to control their
impulses (Braverman and Shaffer 2010). Although this study focused on the behaviour of in-
play bettors, it was noted that some participants engaged in very little in-play betting during
their first month or during the 2-year gambling period. It is possible that these bettors
participated in other gambling activities (e.g., fixed-odds betting) and that these other ways
of gambling contributed to account closure (Braverman and Shaffer 2010). Another limitation
of this study is that it relies on account closers’self-reported gambling-related problems as an
indication of actual gambling-related problems. Subsequently, there is no clinical evidence of
the participant experiencing gambling-related problems.
Brosowski et al. (2012) investigated the associations between participation in different
gambling types and at-risk gambling. They analysed behavioural data from 27,653 bwin
subscribers that included the use of eight gambling products by players over a period of
7 months. They found that 60% of gamblers took part in more than one form of gambling and
that gambling involvement levels, including gambling on multiple game types, were predictive
of gambling-related problems. Engaging in in-play betting or poker were significant predictors
of at-risk gambling after controlling for multiple game involvement. One limitation of this
study is that data were not collected to confirm whether the participant gambled with any other
provider or whether they were the sole user of the account. Secondly, it is not known what
marketing interventions were offered by bwin around the time of recruitment. Brosowski et al.
(2012) suggest that it is possible that a marketing intervention may have artificially increased
the sample with bettors only interested in bonus incentives, who then decreased their betting
activities after taking advantage of the bonus offers on subscription to the site.
Braverman et al. (2013) carried out a study attempting to identify behavioural markers that
can be used to predict the development of gambling-related problems. Approximately half of
the 4056 participants had been received what was termed a ‘responsible gambling (RG) flag’
by bwin. Reasons for receiving RG flags included closing their account due to responsible
gambling-related problems and/or displaying unusual financial and/or verbal behaviours (e.g.,
requesting a higher deposit limit). The other half of the sample consisted of subscribers who
did not have an RG flag at the time of study. This was the control group (n= 2014), and they
were matched by the date of their first deposit. The analysis identified two groups of online
gamblers who had a higher risk of developing gambling problems. The first group engaged in
multiple gambling activities and demonstrated a high wager variability on casino games in
their first month on using the gambling website. The second group participated in two different
gambling types and demonstrated high variability for in-play sports betting. One limitation of
this research was the method used to describe betting behaviour. The difference in the number
of bets and the stake size between the first and second half of the month were calculated and
used this information to categorise the gamblers into one of three groups: stable, increasing,

and decreasing. Braverman et al. (2013) suggest that other methods of categorisation may be
proven useful in predicting gambling-related problems. Another limitation was that the bwin
responsible gambling program is used as an indicator of gambling-related problems but has not
been evaluated against clinical evaluation (Braverman et al. 2013).
LaPlante et al. (2014) reported that people who bet on in-play sports (as opposed to pre-
match betting) were more likely to experience gambling-related problems. In this study, 1440
online surveys were collected from bwin subscribers who completed the Brief Biosocial
Gambling Screen (BBGS; Gebauer et al. 2010). These data were then analysed alongside
online gambling patterns. After controlling for breadth (the number of games an individual
plays) and depth (as measured by the number of days spent gambling) of gambling involve-
ment, the study found a relationship between in-play betting and gambling-related problems
remained. One limitation of this research was that it utilised an online self-report survey (the
BBGS) to assess pathological gambling. An independent clinical validation of the self-
reported BBGS assessment was not provided, and the BBGS is a relatively new screen that
requires further validation. Therefore, the results were subject to limitations associated with
self-report methodology (LaPlante et al. 2014).
Some studies have used the utilisation of online responsible gambling features by players
on online gambling platforms to make inferences about online gambling behaviour including
in-play betting. Gray et al. (2012) examined 2066 bwin subscribers who triggered an auto-
mated responsible gambling (RG) alert. Subscribers triggered RG interventions by engaging
with bwin customer service representatives concerning various responsible gambling tools
(e.g., account closure, voluntary self-exclusion, and deposit limits). When gambling behaviour
of the bwin subscribers was compared to a group of control subscribers, indices of the intensity
of gambling activity (e.g., total number of bets made, number of bets per betting day) for in-
play sports bettors most differentiated those who had triggered the responsible gambling alert
from the control group. A limitation of this particular study was that triggering an RG feature
does not serve as a guaranteed indicator that the user has experienced a gambling-related
problem (Gray et al. 2012; Griffiths and Auer 2016;Nelsonetal.2008). This supports
previous research showing that those using responsible gambling tools such as limit-setting
(Nelson et al. 2008) are more likely to engage in in-play betting than those who do not use
such RG tools. However, if there is an association between engaging in in-play sports betting
and disordered gambling, the direction remains unclear (Gray et al. 2012). A limitation of
using players who set voluntary limits as a population of study is that they may not be
representative of all subscribers with problems. Only a small subset of people with gambling-
related problems actively seek help for that problem (Slutske 2006); therefore, the researchers
are limited with the conclusions that can be proposed about gambling-related problems from
those who do not seek help (Nelson et al. 2008).
Xuan and Shaffer (2009) reported on the behaviour of in-play gamblers using the bwin
dataset. The gambling behaviour of a sample of 226 bwin subscribers who later went on to
close their account was compared to a control group of 226 subscribers. In-play wagering
patterns were a significant behavioural marker for players who then went on to close their
betting account. Those gamblers with account closures demonstrated higher stakes per bet and
increased monetary losses but a more conservative betting strategy prior to closing their
account. Studies by Braverman and Shaffer (2010) and Xuan and Shaffer (2009) complement
the findings of one another in respect to identifying in-play betting behaviours that act as
indicators to future gambling-related problems gambling. However, there are limitations for
the methodology that was used. Behaviour was only analysed for players who closed their

accounts during a select period, a very small proportion of the total bwin sample (1.11 and
0.47% respectively). Only in-play betting behaviour was investigated, and it has been noted
that it is likely that these gamblers also gamble on other games (e.g., fixed odds betting), and
so, other betting activity may have contributed to the closing of the account.
Broda et al. (2008) compared gambling behaviour of those who exceeded deposit limits
(i.e., a voluntary limit set on the amount that can be deposited onto an online gambling
account) with those who did not within a sample of 46,840 bwin subscribers. Their period of
analyses was longer than that of Nelson et al. (2008)—a 2-year period as opposed to
18 months. Broda et al. (2008) found that people who received a notification advising them
that they had exceeded their deposit limit demonstrated a higher involvement in sports betting
(as measured by bets per day and stake size) than players who had not exceeded their deposit
limit. However, only a small percentage of players (0.3%) exceeded deposit limits. However,
this was the only study that reported no difference in betting behaviour between players who
placed fixed-odds bets and those who placed live action (in-play) bets. However, one major
limitation of the study was that although the deposit limit amount that led to issuing a
notification message may differ between participants, it was not possible to analyse whether
different limits were associated with different effects on gambling behaviour because these
data were not available (Broda et al. 2008).
Self-Reported Gambling Behaviour
A few studies utilising self-report methods have been carried out with the aim of attempting to
identify behavioural, psychological and socio-demographic predictors of sports gamblers
(including those who bet in-play). Within a sample of 1816 Australian sports gamblers, more
impulsive sports gamblers were found to have higher problem gambling severity scores and
were more likely to place a higher number of their bets on impulse in-play sports gambling, as
opposed to betting on pre-match outcomes (Hing et al. 2017a). However, the authors noted
that causal directions were unclear because it may be that placing impulsive in-play bets leads
to the development of gambling problems, or conversely, that at-risk and problem gamblers are
more likely to place impulse bets in-play. Therefore, in-play betting may be more likely to
promote impulsive behaviour, although there is currently no empirical evidence available to
support this relationship (Lopez-Gonzalez and Griffiths 2017).
Hing et al. (2016) carried out a study that attempted to identify demographic, behavioural
and normative risk factors for gambling problems amongst a sample of 639 Australian sports
bettors. Sports bettors who engaged in more than one type of gambling showed higher
problem gambling severity (measured using the Problem Gambling Severity Index; Ferris
and Wynne 2001). Higher problem gambling severity was associated with a less planned, more
impulsive approach to sports betting, particularly in-play sports betting. People who planned
and researched their bets prior to an event were found to have significantly lower PGSI scores
than those who did not. Limitations of this study include its use of self-report data that is
subject to recall, social desirability and other biases, and that its use of cross-sectional design
does not allow for the determination of causality (Hing et al. 2016).
Lopez-Gonzalez et al., 2018) explored the association between the use of new structural
characteristics of online betting and gambling severity within a sample of 659 Spanish bettors
who had bet on sports during the previous 12 months. They examined live in-play betting, the
cash out in-play feature, fantasy sports gaming, location of betting and device or platform used
to make a bet. In-play betting was reported to be associated with those who were categorised as
Int J Ment Health Addiction (2019) 17:1456–1495 1465

problem gamblers. They also reported that those categorised as problem gamblers used the in-
play cash out feature more than those who were not. The authors provided several limitations
of the study. The first being that it relied on self-report data which can be subject to biases,
including memory recall and social desirability. Secondly, the study employed a cross-
sectional design, which did not allow for casual implications to be drawn from the results
between the four different variables. Finally, there was a chance that out of those who received
the survey request, those who demonstrated a greater degree of participation in betting
activities were more interested in responding to the survey and resulted in a larger proportion
of problem gamblers in the sample (Lopez-Gonzalez and Griffiths 2018).
Theoretical Papers on Gambling Behaviour
A number of scholars in the gambling studies field have argued that structural characteristics of
gambling, including activities with higher event frequencies, are associated with problem
gambling (Griffiths and Auer 2013; Harris and Griffiths 2017). In short, those activities that
can be gambled on continuously such as slot machines (which can have event frequencies of
up to 30 times a minute on an online slot machine) tend to have a much higher association with
problem gambling than activities such as a bi-weekly lotto game (with an event frequency of
twice a week) (Griffiths and Auer 2013). In relation to in-play betting, Parke and Griffiths
(2007) were the first scholars to speculate that in-play betting may contribute to prolonged,
excessive, un-planned, or problem gambling due to (i) a growth in ‘perceived skill’(through
studying, analysing or spectating the betting event), (ii) chasing losses/winnings on the same or
different sporting event by placing further bets during the event and (iii) by making the
sporting event more stimulating or exciting.
Papers by Griffiths and Auer (2013) and Lopez-Gonzalez and Griffiths (2017)madea
number of similar observations. Previously, bet duration (the time from placing the bet, until its
settlement) was fixed. However, bet durations can now be amended via in-play cash out
features (Lopez-Gonzalez and Griffiths 2017). In-play betting utilising cash out features have
the potential to make sports bettors more vulnerable to cognitive bias (Lopez-Gonzalez and
Griffiths 2017). In the past, sports betting was typically a discontinuous form of gambling with
the vast majority of sports bettors gambling weekly on the outcome of a particular event (e.g.,
a football match). However, some papers have specifically argued that in-play betting and use
of the cash out feature now allows sports betting to be a continuous form of gambling
(Griffiths and Auer 2013; Lopez-Gonzalez and Griffiths 2017). This has radically changed
the traditional sports betting market which was once a discontinuous (low-risk) gambling
activity to a more continuous (high-risk) gambling activity. In-play sports bettors who
experience gambling-related problems may feel more inclined to engage in less planned,
impulsive, and immediate forms of gambling and the time between bet placement and the
reward (or lack of) is greatly shortened (Parke and Griffiths 2007; Griffiths and Auer 2013).
A paper published by Lopez-Gonzalez and Griffiths (2017) is the only paper that explicitly
discusses the implication of in-play cash out sports betting features. They suggested that one of
the implications of cash out in relation to problem gambling is that there is a conception of
gambling on sports as an investment, like that of trading on the stock market. This was then
confirmed empirically showing that sports betting advertisements contribute to self-
perceptions of bettors as specialists of sports, promoting game analysis to beat gambling
companies (Lopez-Gonzalez et al., 2017a,b,c,d). The notion that the bettor can view
themselves as a professional that can improve their probability of winning may serve as a

motivating factor to gamble (Lopez-Gonzalez and Griffiths 2017). Problematic online bettors have
been found to consider themselves to be semi-professional gambler, and in the case of horse racing
bettors, they are more likely to self-report being a professional gambler (Hing et al., 2017a,b).
There have also been a couple of important position papers in the grey literature concerning
in-play betting (see Table 2). The Department of Broadband, Communications and Digital
Economy in Australia commissioned the Allen Consulting Group (2012) to provide advice on
issues relating to in-play betting. At the time the report was produced, it stated that there was no
academic literature on the prevalence of the in-play betting in Australia. The report noted that in-
play betting had grown in popularity amongst the European betting industry, but this growth is
not matched in Australia due to legal betting restrictions. Based on discussion with gambling
providers, in Australia, it was reported that the amount of people using an in-play betting service
is small, but still part of the gambling market (Australian Interactive Gambling Act 2001).
The UK Gambling Commission (2016) produced a report in order to set out their position in
relation to in-play sports betting. Their position is considered in the context of the potential risk that
in-play betting may pose to the three licensing objectives set out by the Gambling Act (2005). These
are B(a) preventing gambling from being a source of crime or disorder, being associated with crime
or disorder or being used to support crime, (b) ensuring that gambling is conducted in a fair and open
way, and (c) protecting children and other vulnerable persons from being harmed or exploited by
gambling.^(Gambling Act 2005, p. 19). One factor that the Gambling Commission considered was
whether this particular gambling activity could be harmful. In 2009, the Gambling Commission
previously reported that there was no evidence to suggest that in-play betting posed a greater specific
risk of causing gambling-related hard than other forms of online gambling. In the 2016 report, they
noted that since 2009, more research has been carried examining potential associations between in-
play betting and gambling-related harm.
The Gambling Commission report (2016) suggested that there could be a greater risk of
harm from gambling for those who participate in in-play sports betting compared to those who
participate in other forms of gambling. The first example that the Gambling Commission
provided was that in-play gambling provides the opportunity to place more frequent bets on
the same event, and some research suggests that there is an association between this increased
opportunity, or to be ‘rewarded’with an increased chance of experiencing gambling problems

(Griffiths 2012). Secondly, they cited Australian research from Hing et al. (2016) demonstrat-
ing an association between tendencies to place a higher number of in-play bets with an
increased risk of harm from gambling. Finally, they cited figures from a Gambling Prevalence
Report (Gambling Commission 2017) which indicated that 27.4% of online gamblers who bet
in-play were classified as problem gamblers, compared to 10.9% of all online gamblers and
5.4% of online gamblers who do not bet in-play. Consequently, it was noted that those who bet
in-play are at greater risk of harm from gambling than those who do not bet in-play. The report
concluded that based on the evidence review, the UK’s current regulatory system of in-play
betting was sufficient and that no further controls were required at the time of writing.
Current In-Play Sports Betting Products
At the time of the present scoping review, three different online in-play betting features are
currently being used by online sports bookmakers (cash out, ‘Edit my Acca’,and‘Edit my
Bet’). There are also two other features were identified that at the time of writing were in the
process of being introduced and/or developed (‘Add 2 Bet’and ‘betting using GPS tracking’).
These features are described in detail below:
‘Cash Out’The first online sports betting provider to offer the option to cash out bets was
William Hill in 2012 (Gaming Intelligence 2014). Since the introduction of this in-play
product, many European online operators have followed suit and made this product an
available feature on their website via a desktop or mobile device. Betfair provided the
following description of the in-play cash out feature:
BCash Out lets you take profit early if your bet is coming in, or get some of your stake back
if your bet is going against you—all before the event you’re betting on is over. Cash Out offers
are made in real time on your current bets, based on live market prices. Whenever you are
ready to Cash Out, simply hit the yellow button. Cash out is available on singles and multiples,
on a wide range of sports, including football, tennis, horse racing, and many more! You can
Cash Out of bets pre-play, in-play, and between legs^(Betfair 2017).
There are several different types of cash out. Operators such as Bet365 offer the option to
‘partially cash out a bet’(the gambler can choose how much of their bet they wish to cash out)
and ‘auto cash out’—the gambler can select a value and if this value of the bet is reached, then
it is automatically cashed out (Bet365 2017a).
Edit My Acca (Accumulator Feature) The second identified in-play betting product that
has been introduced to the sports betting market is the ‘Edit my ACCA’feature. In May 2016,
Ladbrokes introduced this feature to the in-play betting market (Ladbrokes 2017). This feature
allows gamblers to remove selections from their accumulator after the bet has been placed and
in some instances after the selected event has started. The betting slip is then revised to feature
the amended selections and a new potential return amount. This can be done online or via a
mobile device (Ladbrokes 2017).
Edit My Bet Thirdly, ‘Edit my bet’is an in-play betting feature that was introduced by Bet365 in
January 2017 (Bet365 2017b). The ‘edit bet’feature can be used by gamblers to ‘unsettle straight
accumulators’before matches have started or whilst they are in-play (Bet365 2017b). The feature
can also be used for to swap single bets for new bets, and the gambler is given a new bet selection
valued at Bet365’scash out price to reflect live market/game odds for the original bet.

Add2Bet ‘Add2Bet’is one of the latest betting products to be introduced to the betting
market, and provided by SBTech (2017). This new live betting feature is aimed at both players
and gambling operators. Add2Bet has been described as Bamobile-focusedenhancement,
designed around simplicity and ease-of use^(SBTech 2017,p.1).This new live betting
feature allows gamblers the option to instantly use the cash out value of an open bet to create a
new bet type—a new double, treble, or acca (accumulator)—by combining it with new
selections. It has been advertised as giving players more control over their betting and appeals
more effectively to millennials (SBTech 2017). During initial trials of the feature, (which is yet
to go live at the time of writing this scoping review), it was found that those aged under
35 years were early adopters of the feature, Bwith players from this age group trying Add2Bet
after seeing it just twice on average, whereas older users waited until they had viewed it an
average five times^(SBTech 2017, p. 1). Of the sample included in testing the new feature, it
was found that 7% of English Premier League football live bets utilised the Add2Bet to edit an
existing live bet. Furthermore, almost 70% of player who used cash out for approximately 40%
of their betting activity placed a bet using the new feature.
Betting Using GPS Tracking The final in-play betting feature identified is betting using
GPS tracking technology. According to online news stories, UK betting providers are prepar-
ing the introduction of in-play horserace betting that includes the use of global positioning
system (GPS) technology (Streeter 2017). Gamblers looking to place a bet on a live horse
racing event will be able to view the horse positions within the race (which may have
previously been undetermined due factors such as the speed of the race, or confusion over
the distinguishing jerseys worn by the jockeys) using the GPS tracking system. The aim of this
is to aid online sports betting customers to make a decision. Gambling operators Paddy Power
and Bet365 are already manually offering in-play wagering markets on horse racing markets.
However, it has been proposed that this feature will have an average accuracy of the horse’s
position within 0.1 m, all delivered within a maximum time lag of 0.1 s. The UK racing sports
turnover in 2016 generated £5.64b; therefore, it has been predicted that this new feature will
increase profits for online gambling companies (Wood 2017).
In-Play Sports Betting Products on Online Bookmakers’Websit es
Of the 513 online sports betting websites reviewed, it was possible to access 338 of these at the
time of carrying out the research. Reasons for not being able to access specific bookmaking
sites included that the site was (i) no longer active, (ii) not possible to access from the UK due
to betting regulations, or (iii) blocked for security reasons.
Of the 338 websites accessed, 88 of these (26%) offered at least one in-play betting feature
(see Appendix Fig. 1). All 88 online gambling websites offered ‘full’cash out on selected
markets, and 29 of the websites also offered the option of ‘partial cash out’. Two websites
offered ‘auto cash out’, where cash out ‘rules’can be created with no further input from the
bettor. Once a selected value reached, then the bet is automatically cashed out. Website
accessibility determined by specific device type was categorised into two groups: (i) desktop
(a computer that is suitable for use in one location) and (ii) mobile (a device that can be used
on the move such as a smartphone, laptop or tablet). Three gambling websites only allowed
cash out to be accessed via a desktop computer or laptop and one website via a mobile device
only (e.g., a smartphone device, laptop, or tablet computer). A total of 77 sites offered the cash

out facility via desktop or mobile device, and two sites allowed bets that were placed in a land-
based betting shop to then be cashed out via a desktop or mobile device.
In terms of bet types that were able to be cashed out, the most commonly offered amongst
those that provided in-play betting was single and accumulator bets (58 websites). An
accumulator bet, also known as a multiple or parlay bet, is a single bet that links together
more than one bet and is dependent on each individual bet being successful in order to result in
an overall winning bet. Eight of the websites only allowed for single bets to be cashed out; one
website stated that ‘all bet types’could be cashed out, and 22 of the websites viewed did not
explicitly state what bet types could be cashed out. In terms of named sports that were eligible
for the cash out facility, football (soccer) was the most popular. Three of the sites only offered
cash out to football bets, and 23 allowed football bets to be cashed out with a range of other
sports available also. A majority of the websites visited that provided in-play betting (n=54)
did not explicitly state which sports cash out would be available for. In terms of market
eligibility for cash out, for example ‘full time result, ‘number of goals’and ‘both teams to
score’, 58 websites did not explicitly state which markets were available for cash out, whereas
30 websites did. One sports betting operator (Ladbrokes) operated the in-play betting feature
‘Edit my Acca’feature (described in the previous section), and one operator (Bet365)offered
the in-play feature ‘Edit my Bet’(also described in the previous section).
General Discussion
The present scoping review is a first attempt to scope the literature and present information on
what is known about in-play sports betting. To date, the most commonly used empirical method
of investigating in-play gambling behaviours has been via the use of behavioural tracking data
(although all of this has come from the same bwin dataset to date). Research published using the
bwin dataset has reported that engaging in in-play gambling appears to be an important marker for
gambling-related problems (LaBrie et al. 2007;LaPlanteetal.2008;Nelsonetal.2008). These
studies described gambling-related behavioural factors associated with highly involved sports
bettors (e.g., number of bets and the total amount wagered) and identified a sub-group of bettors
who maintained a high involvement in online gambling via in-play betting (LaBrie et al. 2007;
LaPlante et al. 2008). Other studies found that participation in in-play sports betting is an
independent predictor of problem gambling severity when gambling involvement is controlled
for (Brosowski et al. 2012; Xuan and Shaffer 2009). It was also found that gamblers who utilised
an online provider’s limit setting tool was more likely to engage in in-play betting than other
forms of gambling (Gray et al. 2012;Nelsonetal.2008). After setting a voluntary limit, those
who previously participated in fixed-odds and in-play sports betting were more likely to stop
betting in-play than to stop betting on fixed-odds selections (Nelson et al. 2008). Nelson et al.
(2008) suggest that this could indicate that the players consider in-play betting to be more of a
risk. Overall, the reviewed studies suggest that multiple, frequent and larger in-play bets appeared
likely indicators that differentiated high-risk sports bettors from lower risk sports bettors.
Although the results described using the bwin dataset allow for real-life gambling behaviour
to be studied, they are not without limitations. Firstly, studies that utilise these datasets did not
describe the gamblers’perceptions, clinical characteristics or the social consequences associ-
ated with their betting behaviour (Griffiths 2014; Shaffer et al. 2010). There was no informa-
tion provided about users’income (Shaffer et al. 2010), and previous research has indicated
that the impact of gambling is partially dependent upon the gambler’s financial status;
Int J Ment Health Addiction (2019) 17:1456–1495

therefore, it is necessary to consider the amount spent gambling in relation to the amount of
money that is available (Gray et al., 2012). Due the lack of psychosocial information about the
meaning and consequences of gamblers, it is not possible to infer any clinical characteristics
regarding the impact of internet gambling on the lives of individual subscribers (Griffiths
2014; Shaffer et al. 2010). One disadvantage of using online behavioural tracking is that
internet gamblers may also gamble both online and in person, for example, at casinos or other
gambling venues, and are unlikely to gamble at just one site (Wardle et al. 2011). Therefore,
estimates of Internet gambling usage may not be an accurate representation of how much
Internet subscribers gamble (Shaffer et al. 2010).
In relation to the self-report studies and academic theorising concerning in-play sports
betting, researchers have constantly referred to the role of structural characteristics in the
acquisition, maintenance and development of online gambling behaviour (Parke and Griffiths
2007) and have demonstrated an association between problem gambling and such features as
event frequency, bet frequency and the speed of rewards (Griffiths 2012; Harris and Griffiths
2017). The gambling study literature has suggested that in-play sports betting may offer more
of a risk to problem gamblers because it allows the option for high-speed continuous betting
and requires rapid and impulsive decisions in absence of time for reflection (Hing et al. 2014a,
2014b,2014c; Lopez-Gonzalez et al., 2017a,b,c,d;Nelsonetal.2008). Therefore, in relation
to problem gambling, in-play betting offers structural factors that may contribute to the
development of gambling-related problems. These characteristics include, but are not limited
to bet frequency, event frequency, event duration, and pay-out frequency. Research has found
in-play betting to be associated with people who were categorised as problem gamblers
(Lopez-Gonzalez et al., 2018). Lopez-Gonzalez and Griffiths (2018) offered a potential
explanation for this. More specifically, gamblers who are experiencing gambling-related
problems may be inclined to place impulsive, less planned and readily available forms of
gambling such as in-play. However, using the data from the present studies is not possible to
identify a causal link between problem gambling and the use of different gambling types due
to the correlational and cross-sectional nature of the few studies that have been carried out to
date (Lopez-Gonzalez et al., 2018).
In relation to the primary data collected by the present authors visiting sports betting websites,
the results demonstrated that 26% of online gambling websites offered at least one in-play
betting feature. Given that previous empirical research has shown that games that offer a fast,
exciting play and regular wins tend to be associated with problem gambling (Parke and Griffiths
2007), it could be that the structural characteristics of in-play betting features such as cash out
facilitate problem gambling in vulnerable and susceptible individuals. Empirical research to date
indicates that individuals characterised as impulsive sports bettors are more likely to bet on in-
play matches than overall outcomes (Hing et al., 2017a). However, further empirical research is
required in order to explore whether in-play betting plays a role in excessive or un-planned
gambling. The UK Gambling Commission (2016) concluded that those who bet in-play are at
greater risk of harm from gambling than those who do not bet in-play, but that no further
regulation is currently required in the UK gambling market for in-play betting.
It has also been argued that the online aspect of gambling, a new situational as well as
structural gambling characteristic of many gambling products, has changed the interaction
between gamblers and gambling and may therefore increase the likelihood of gambling-related
harm (McCormack and Griffiths 2013). The results of this current scoping study demonstrated
that in-play betting features could be accessed via a mobile and desktop device in 87.5% of
cases of the sport betting websites visited. This increased accessibility to online gambling

platforms and the ease of interaction on platforms such as smartphones may accelerate the
acquisition of maladaptive learned behaviours such as problem gambling (James et al. 2016).
Again, further empirical research is required to explore whether technological advances and
the ease of access to bet in-play increase the likelihood of a person experiencing gambling-
related harm.
Limitations
A strength of scoping studies includes rigorous and transparent method of mapping evidence
covered in a given field (Davis et al., 2009). However, practical issues relating to time and the
fluid nature of the research area being explored must be considered, as well as the issue
concerning the ‘quality’of data collected (such as the data collected via visiting online
gambling websites). With regards to the present study, the scoping study method allowed
the possibility of illustrating the field of in-play betting product availability. This was achieved
by reviewing many online gambling websites. The research team viewed as many websites
available as possible. However, all available gambling websites were not reviewed. In total,
338 out of the 513 gambling were visited. This was due mainly due to country legislations
which blocked accessibility to multiple online gambling websites.
Only a small number of empirical studies were identified during this scoping review. There
was a large reliance on behavioural tracking data which does not explain why people are
engaged in such behaviours. Additional limitations of using behaviour tracking research are
related to the ethical issues of using gamblers’behaviour data without their awareness, and
therefore, there is a lack of informed consent. This scoping study also identified very few self-
report studies, and no studies employing other methodologies were identified (e.g., experi-
mental studies, observational studies).
The aim of the present scoping study was to review the contemporary literature empirically
investigating or theorising about in-play sports betting and collate information about in-play
sports betting features available to gamblers within the online sports betting market. Under-
standing factors that determine in-play betting behaviour, including understanding the risk
factors for problem gambling amongst in-play sports bettors, is an important area of research
given the continuing growth of the online sports betting industry. Overall, the research
suggests that this way of gambling has the potential to be more harmful than other ways of
gambling (e.g., gambling on fixed odds) because of the inherent structural characteristics.
However, to date, there has only been one study that explores online sports betting behaviours
in the context of specific in-play betting features (i.e., Lopez-Gonzalez and Griffiths 2018).
