21点游戏规则：庄家给每个玩家发两张牌，牌面朝上；给自己发两张牌，一张牌面朝上(叫明牌)，一张牌面朝下(叫暗牌)。大家手中扑克点数的计算是：K、Q、J 和 10 牌都算作 10 点。 A 牌既可算作1 点也可算作11 点，由玩家自己决定。其余所有2 至9 牌均按其原面值计算。目的是尽量往21点靠，靠得越近越好，最好就是21点了。在要牌的过程中，如果所有的牌加起来超过21点，玩家就输了——叫爆掉(Bust)，游戏也就结束了。假如玩家没爆掉，又决定不再要牌了，这时庄家就把他的那张暗牌打开来。假如他现在的两张牌加起来小于或等于16点(Hit)，他就必须继续给他自己发牌(不管他的点数是否比你大)，一直发到他的点数大于等于17点为止。庄家在给自己发牌的过程中，假如他爆掉了，那他就输了。假如他没爆掉，那么你就与他比点数大小，大为赢。一样的点数为平手。-Blackjack game rules: banker to each player hair two CARDS, CARDS face, Give oneself to send two card, a piece of card face (called Ming card), CARDS face down (called dark card).
