三子棋是一种民间传统游戏,又叫九宫棋、圈圈叉叉棋、一条龙、井字棋等。游戏分为双方对战,双方依次在9宫格棋盘上摆放棋子,率先将自己的三个棋子走成一条线就视为胜利,而对方就算输了,但是三子棋在很多时候会出现和棋的局面。
两个玩家,一个打圈(◯),一个打叉(✗),轮流在3乘3的格上打自己的符号,最先以横、直、斜连成一线则为胜。
如果双方都下得正确无误,棋盘将会被填满而和局。
这种游戏实际上是由第一位玩家所控制,第一位玩家是攻,第二位玩家是守。
第一位玩家在角位行第一子的话赢面最大(见图一),第二位玩家若是在边,角位下子,第一位玩家就可以以两粒连线牵制著第二位玩家,然后制造“两头蛇”,所以他必须下中央。如第一位玩家下在中央,则第二位玩家必须下在角位才不会输。如第一位玩家下在边位,第二位玩家可以下在中央或角位,或是与第一位玩家下的位置相对的边位。
创建一个菜单界面,当输入1时进入游戏;
当输入0时退出游戏;
当输入其他数时输入错误,重新输入。
