Digital dementia becomes an issue these days which causes failure of one’s memory and calculation ability because many people rely heavily on digital devices, such as smart phones. Smart devices themselves become smarter and smarter whereas digital device users become dumber and dumber, and finally they are suffering from digital dementia. Serious games can be defined as games which combine entertainments with various applications. They relieve the negative opinions which belong to existing games, so many game titles have been released as serious games in these days. This research is motivated by the fact that serious games were originated to overcome practical issues. In this paper, a serious game is presented to prevent digital dementia and its effectiveness is shown. The proposed serious game is composed of simple four fundamental arithmetic operations which improve one’s calculation ability. Since simple arithmetic operations are familiar regardless of one’s age, they are chosen. Everyone can enjoy the game beause random factors are added. This paper concludes that serious games can be used to prevent digital dementia very effectively.
