The teaching of financial literacy through game-based approaches is legitimized by the ability of game-based learning (GBL) to simulate financial decisions that young people have not yet encountered in their lives due to limited legal capacity and economic dependence on the parental home. Although results on the general effectiveness of games are already available, the question about for which students GBL is effective in teaching financial literacy has not yet been researched in depth. Based on pedagogical interest theory, a pre-post design (n = 50; 30 female students) was conducted to investigate the effects of high school students' individual prerequisites on their game experience and their development of situational interest by playing an analog game and debriefing. The main findings indicate that a higher level of prior motivation for this topic has a positive effect on game experience and situational interest. A high level of prior knowledge and leisure activities concerning finance may have a somewhat negative effect. Such games are particularly suitable for students who are aware of the subjective significance of finance but have not previously had the opportunity to engage with this topic for different reasons.
