As a starting point, previous research has been studied and one of them suggests questions for further research, so they have been used to make this empirical thesis. The paper includes the theoretical part of the game and its significance for the overall development of the child with an emphasis on kinesiology, to be more precise, spontaneous play with elements of motor play. Some examples of them are presented, researches related to gender differences are shortly mentioned, and the paper also contains a methodological part accompanied by graphs that illustrate the results. The research aimed to show how and to what extent gender influences the choice of spontaneous play, the way, type, course, and goal of the game, the use of props, and the formation of a group. The research was conducted in the city of Zagreb and the western part of Zagreb County on a sample of 13 children by observation and conducted an interview. It was found that girls and boys play all games equally, do not make a difference when choosing a partner to play, play dynamic games of moving content and spend a lot of time in the fresh air. It is also evident that gender plays no role in the selection of props or the formation of a group. The boys practice competition games and this is the only obvious difference in the whole research.
