The game has three basic function modules to realize the fundamental operation of combat between players and mobile phones. The first module is the design of login interface, including an invisible list for the choice of players. The second one is the detailed operation of chessman during the game, including the choice of place for the next moving, design of chessman and renewal of interface, and the choice of players. This part enables the calculation control of chessman outside the interface and the overlap problems, and enables the intelligent control of combating mobile phones. The third one is the control of game exit. It checks the game condition and judges whether it is finished, and then analyzes to get the result who is the winner.
