As modern technologies develop, the world of digital games has changed remarkably and gained a new character. It is apparent at present that playing digital games, ie electronic games that can be played by means of a PC, mobile phone, tablet, game console, and other devices, is becoming one of the very favourite leisure activities for children and adolescents. This article introduces a survey of the current status of digital game playing among Czech adolescents, obtained through representative research among 3950 respondents from all over the country aged between 11 and 19. This research was performed by the Department of Psychology of Palacký University in Olomouc in 2018. The standardised scales applied in this study provide us with the prevalence of disturbances relating to playing digital games in the population of adolescents and an assessment of the size of the population at risk of addiction to game playing in the Czech Republic.
