Household food waste poses significant environmental, social, and financial challenges. This systematic literature review examines the role of games and gamification in mitigating food waste, addressing four key research questions: how these interventions are applied, their impact on attitudes and behaviors, the specific mechanisms employed, and their measured outcomes. The analysis identifies a

Theoretical frameworks such as the Theory of Planned Behavior, emotional engagement, systems thinking, and cognitive load theory underpin these interventions. Findings suggest that gamification can enhance awareness, knowledge, and behavioral change, with some interventions demonstrating measurable reductions in food waste. However, limitations such as the lack of long-term engagement data, varying effectiveness across socio-economic contexts, and inconsistencies in measurement frameworks remain challenges. Notable interventions—including the MySusCof and Exspiro apps and serious games like FoodFighters and PadovaGoGreen—show promising results but require further validation in diverse settings. This review highlights both the potential and limitations of gamified strategies, emphasizing the need for standardized measurement approaches and longitudinal studies to assess their sustained impact on food waste reduction.
