规则： 与“传统的五子棋”（这里指的是没有禁着的五子棋）非常相似， 规则非常简单仅有以下三条： 玩家： 如五子棋及围棋，有黑白两方，各持黑子与白子，黑先。 玩法： 除了第一次黑方下一颗子外，之后黑白双方轮流每次各下两子，直的、横的、斜的连成 6 子（或以上）者获胜。 若全部棋盘填满仍未分出胜负，则为和局。没有禁手；例如长连仍算赢。 棋盘： 因为公平性不是问题，棋盘是可以任意地大，甚至是无限大亦可。然而为了让游戏可实质地来玩，目前棋盘采用围棋的十九路棋盘。
本文使用代码为纯C代码，适合初学编程的同学理解使用，高级代码详见c#版六子棋代码。 注：C语言很难实现界面交互化，此系统使用的是printf打印刷新方式进行对弈，棋盘打印只适用于win7电脑环境，win10或其他系统会有bug嗷！
