With the development of media technology and game evolution, games are endowed with multiple purposes and functions. Some scholars believe that the game is the supplement of the real world, which can affect the players' psychology and behaviour. Numerous studies show that games can make players accept challenges, overcome obstacles, arouse positive emotions and solve problems. Therefore, academia's research on games and related topics in learning has become increasingly popular. In response, different models have emerged to evaluate the design of active educational games. This research discusses how different game mechanisms affect players. Also, this study used a prototype game as output media to examine the impact of various game mechanisms on learning. The purpose of this study is to explore how to choose a more suitable game mechanism in the design of educational games. The research results include that some game mechanisms promote learning motivation and improve learning outcomes. At the same time, some game mechanisms have the risk of reducing learning motivation. Through these findings, the researcher of this study believes that educational games can bring positive influence and help to players' learning. However, how to choose a suitable game mechanism in the design of educational games is worthy of serious consideration for making design decisions.
