小卡和欢总喜欢玩一个小游戏，游戏界面是4*4格子的棋盘，每个格子可以放一个棋子。



最开始的时候棋盘上只有一个棋子，叫 T 。



接下来欢总和小卡轮流放棋子，小卡的棋子是 X ，欢总是 O 。



如果有一行或一列或一条对角线上全部是某个选手的棋子（4个）或者3个他的棋子和 T ，这个选手就赢了，游戏结束。 如果所有格子都满了，没有人赢，以平局结束。-Small card and joy always like to play a little game, the game interface is a 4* 4 chessboard grid, each grid can put a piece.
