    一、游戏介绍

    1.1 游戏规则

    21点又名黑杰克,该游戏由2到6个人玩,使用除大小王之外的52张牌,游戏者的目标是使手中的牌的点数之和不超过21点且尽量大。

    1.2 牌点计算

    A至10牌,按其原点数计算;J、Q、K都算作10点。

    1.3 判断胜负

    二十一点www.devze.com玩法规则和概率在二十一点游戏中,拥有最高点数的玩家获胜,其点数必须等于或低于21点;超过21点的玩家称为爆牌。拥有最高点数的玩家获胜,其点数必须等于或低于21点;超过21点之间判负。

    二、游戏设计

    2.1 游戏流程

    发牌:

    玩家和AI每人发两张牌,由手牌点数和大的玩家优先选择是否在牌堆中取牌

    取牌:

    手牌点数和小于21,等待1中优先选择后再顺时针轮到其他玩家选择是否取牌

    取牌后:

    若牌点大于21则直接判负出局,场上只剩1人,直接游戏结束;否则重复2-3

    若牌点小于等于21则轮到下家取牌,重复2-3

    游戏结束

    其他玩家取牌后都超过21点,只剩1人,直接获胜

    所有玩家都选择不取牌后,按规则比较所有玩家手牌点数和,牌点大的获胜。

    2.2 玩家类

    由玩家自己选择是否继续拿牌。(输入Y继续拿牌,N为不拿牌)

    2.3 AI类

    简化AI逻辑,发牌后AI手牌和为4-8时继续拿牌,一直到17点或17点以上不再拿牌;因为此时再拿牌就有一半以上的概率超过21点。
