What's a plate? How to play?

There are 80 cards in China, of which four are called "Freshman" and "Sophomore" and four are called "One", "Two" and "Ten".

When playing cards, the dealer draws 2 1 card and the leisure family draws 20 cards. Similar to mahjong, the cards in their hands are combined into 3 (or 4) closed piers, which are as follows:

1, opening: four pieces of the same value (such as "Xiao Qi" four pieces);

2, Kanzi: three pieces of the same value;

3. Half: (for example, 2 "big five" plus 1 "small five");

4. Straight: (such as "Small Four", "Small Five" and "Small Six");

5. There is also a unique number plate called twenty or seventy (such as "sophomore", "big seven" and "big pick");

6. Pairing: If there is an opening move in the card type, it is good that the two piers have the same value.

In fact, the whole process of playing cards is the process of constantly collecting cards until Hu cards. In the process of playing cards, you can eat cards (form a straight or a half) and touch cards (form a hurdle). You can touch the cards played by any family as long as you can touch them, but you can only eat the cards played by this family. Whether to eat or touch, the player can decide for himself. After eating or touching, the cards must be turned over on the table (everyone can see them, that is, bright cards).

Note that there are three main differences between signboards and mahjong.No. 1, signboards are not allowed to "check cards", that is, if you have two cards, Xiao Wu and Xiao Liu, and your family plays "Xiao Si", you don't eat them. After a while, your family will play "Primary Four" again, and you will lose the qualification to eat Primary Four. Similarly, the printing plate is not allowed to touch the "cover". This requires a prior judgment on what cards to eat and touch at the beginning of the game. Second, in the starting hand, more than three cards cannot be divided. For example, if you have three big hands, you can't combine one of them into a straight, such as "Big Five, Continental, Big Seven". Third, implement the "fire law". If you already have a small eight in your hand and want to eat it when you play it at home, you must be able to combine it into two piles and show your cards at the same time, otherwise you won't be able to eat it. The computer can automatically judge whether you can eat cards. When the computer doesn't give a prompt to eat the card, it means that you can't eat the card and you can't get angry.

But there are some situations that are mandatory by the rules (whether you like it or not, you must do it). They are:

1, card sweep: If you have two cards of the same value in your hand and you catch 1 cards of the same value when you draw cards, you must combine them into a hurdle. This process is called card scanning. After sweeping the cards, the cards must be placed on the desktop but cannot be opened (others don't know what cards they are, that is, dark cards);

2. Playing cards in hand: When you draw cards, you already have three cards of the same value in your hand. In the process of playing cards, when any family plays the same card, they must open cards to form four cards with the same value; (bright card)
