Abstract: Among all the possible applications of BCI, game is an important application direction. BCI can enrich game play by the mental and affective state information they contain, and games will promote BCI technology application in turn. This paper puts forward and realizes BCI mutiplayer minesweeper game system for the first time, which applies the player’s motor imagery and P300 potential electroencephalogram（EEG） as the control signal of minesweeper cursor, and realizes the combination of motor imagery and p300 potential and applies these two models to minesweeper game. This paper introduces the implementation process of game system and presents the experiment results from eight subjects. The experiment results show the feasibility of applying these two models to game.

Key words: brain computer interface, motor imagery, p300 potential, game
