In this study, we applied a design-based research methodology to develop “Eat Healthy,” a digital board game that promotes healthy eating. The game was designed as a digital event card system, supported by a web-based platform for card drawing. An innovative feature of this research is the integration of tablet and smartphone sensors into board gameplay, expanding the possibilities for interactive learning and user engagement. By aligning with the principles of Environmental, Social, and Governance, and Sustainable Development Goals, this approach also explores pathways for embedding sustainability into the board game industry. In this study, we endeavored to raise participants’ awareness of the six key nutrients and their optimal dietary proportions, while concurrently examining players’ attitudes toward the use of sensor-based mechanisms in board games. To evaluate the effectiveness and user satisfaction of this digital board game, we employed a five-point Likert scale questionnaire survey, selecting 38 university students as research participants, who were divided into groups, with each group provided a tablet. They scanned a QR code to access the “Eat Healthy” digital-event-card-drawing webpage, replacing traditional paper-based card drawing with a digital method. Questionnaire data revealed that the board game effectively promoted awareness of healthy eating among players, who also expressed considerable enjoyment of this novel gameplay approach. Future recommendations include increasing game difficulty and diversity to boost engagement and interactivity, along with adding an offline mode for drawing digital event cards without an internet connection to improve accessibility.
