E-sports games have recently become a popular internet game especially among young people and are played at a professional and amateur level. The effect of replacing traditional games with such digital games on the development of children and young people is hotly discussed among the parents and educators. This study aims to investigate psychological problems of players arising from playing e-sports games. The research was designed with a survey model. The sample consisted of 100 players that were accessed over the internet. The data were collected using an electronic questionnaire prepared by adapting the computer games addiction scales. The majority of the participants are high school students and their average age is 17.5 years. About half of them have e-sports experience of five years and above. It is seen that the participants have low level addiction problems in the dimensions of "associating e-sport with real life" and "neglecting responsibilities because of e-sport" and medium level addiction problems in the dimensions of "preferring e-sport to other activities" and "can not giving up e-sport". Gender, age and school type have no effect on these dimensions. [For the full proceedings, see ED623149.]
