Gamification is an effective strategy for motivating and engaging users, grounded in business, marketing, and management by designing games in non-game contexts. Gamifying education, the design, and study of educational games, is an emerging trend. However, existing classroom games for understanding macroeconomics have weak connections to the micro-foundations of individual decision-making. We design an educational game on cryptocurrency investment for understanding macroeconomic concepts in microeconomic decisions. We contribute to the literature by designing game-based learning that engages students in understanding macroeconomics in incentivized individual investment decisions. Our game can be widely implemented in online, in-person, and hybrid classrooms. We also reflect on strategies for improving the user experience for future educational game implementations.
