一字棋游戏是一个流传已久的传统游戏。游戏由两个人轮流来下，分别用“X”和“O”来代替自身的棋子。棋盘分9个格，双方可以在轮到自己下的时候，可以用棋子占领其中一个空的格子。如果双方中有一方的棋子可以连成一条直线，则这一方判胜，对方判负。当所有的格子都被占领，但双方都无法使棋子连成一条直线的话，则判和棋。(Word chess is a long tradition game. The game is played by two turns, each with its own "X" and "O" instead of its own pieces. The chessboard is divided into 9 squares, and the two sides can occupy one of the empty compartments with their pieces when it's their turn. If the pieces of one of the two sides can be connected in a straight line, the party wins and the other side loses. When all the boxes are occupied, but the two sides can make pieces in a straight line, and then sentenced.)
