Augmented reality development continues to speed up these days, however, in video games, the use of augmented reality is supportive only and it does not achieve an immersive experience. In this paper, we develop a game for mobile devices called ARSOCCER. This is a soccer game that uses augmented reality to show the entire game in real physical spaces like tables or floors. ARSOCCER works online, giving players the ability to play remotely in real time. It also has algorithms based on knowledge agents to control the game bots. Multiple users tested the game, divided into two groups, playing against artificial intelligence and with other users. These user groups have shown compliance (85% satisfaction) with the immersive experience that ARSOCCER can offer.
