游戲介紹

五子棋是全國智力運動會競技項目之一，是一種兩人對弈的純策略型棋類游戲。

五子棋有兩種玩法。玩法一：雙方分別使用黑白兩色的棋子，下在棋盤直線與橫線的交叉點上，先形成五子連線者獲勝。玩法二：自己形成五子連線就替換對方任意一枚棋子。被替換的棋子可以和對方交換棋子。最后以先出完所有棋子的一方為勝。

五子棋的棋具與圍棋通用，是一種傳統(tǒng)的棋種。

五子棋容易上手，老少皆宜，而且趣味橫生，引人入勝：它不僅能增強思維能力，提高智力，而且富含哲理，有助于修身養(yǎng)性。

游戲規(guī)則

（1）對局雙方各執(zhí)一色棋子。

（2）空棋盤開局。

（3）黑先、白后，交替下子，每次只能下一子。

（4）棋子下在棋盤的空白點上，棋子下定后，不得向其它點移動，不得從棋盤上拿掉或拿起另落別處。

（5）黑方的第一枚棋子必須下在天元點上，即中心交叉點

（6）輪流下子是雙方的權(quán)利，但允許任何一方放棄下子權(quán)（即：PASS權(quán)）。

五子棋對局，執(zhí)行黑方指定開局、三手可交換、五手兩打的規(guī)定。整個對局過程中黑方有禁手，白方無禁手。黑方禁手有三三禁手、四四禁手和長連禁手三種。
