Introduction: It is important to educate undergraduates about communication errors in clinical sites, but it is difficult for clinically inexperienced students to imagine those errors. Therefore, in this study, a board game (BG) was developed and put into practice to encourage students' understanding.　Methods: The BG consists of a board on which the patient's name is written and cards on which drug names are written. Students place cards on the board according to the teacher's instructions. These instructions include multiple traps based on actual incident cases. Through the game, students experienced errors.　Reflection: This BG contains gamification elements that make learning contents simple and fun and simulation elements that reproduce errors with high fidelity. By combining these elements, it is possible for each aspect of the ARCS model to be provided in a well-balanced manner, even in patient safety education for clinically inexperienced students.
