One of the game-based learning principles that allows users to benefit from the game is the development of problemsolving skills [41], and educational games can assist users in developing these skills [41,42]. The modalities of game content representation should be adjusted to boost motivation and performance [43]. If learners cannot understand the app's content, no matter how rich and useful it is or how beautiful the design is, the app's entire instructional value is lost [44]. ...
