This paper describes the development of didactic games through history, their forms and applications, and the importance of using games in teaching mathematics. Through games, children are motivated to work, and their creativity and collaboration are encouraged. The most important parts of the didactic game, namely its environment, purpose, procedure and rules are described in this paper. It is important to emphasize that before choosing didactic games in teaching mathematics, we first have to determine the educational goal that we want to achieve by using that game, consider its suitability for students and, if necessary, adapt it to the students. In order for students to be active during class and motivated to work, it is necessary to change games and introduce new ones. Didactic games are divided into two categories, cooperative games and individual games. Cooperative games are further divided into games for multi-member teams and games for a team of 2 students, while individual games are divided into single-player games and twoperson games. A suitable didactic game is listed and described for each category.
