C#实现扑克游戏(21点)的示例代码

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。
