Project participants rarely have opportunities to reflect on Muri, and it is difficult to measure its effects on project performance—such as time and cost. One effective way to enhance awareness of Muri and help project participants understand its impact is through educational simulation games. This approach allows participants to actively engage in decision-making and observe the consequences of their actions through embedded feedback mechanisms. This research introduces the Muri Puzzle Game, an educational simulation designed to teach the concept of Muri and raise awareness of its impact on the time-cost trade-off. Specifically targeting Muri in labor, the game was tested with 43 participants, with data collected through pre-and post-questionnaire surveys. The experimental results indicate that the Muri Puzzle Game effectively enhances participants’ understanding of Muri in labor and its influence on project performance, particularly regarding time-cost trade-offs. These findings contribute to the body of knowledge on Muri by providing a practical tool to facilitate its recognition and improve workforce management in construction projects.
