For players new to mahjong, one of the most confusing issues isHow to think about how many cards Mahjong has?。Obviously, the cards in your hands look similar, why sometimes they can play, but sometimes they can't? In fact, judging the number of Hu cards is not complicated. As long as you master the basic Hu card type structure and calculation method, you can easily understand how far you are from Hu cards. This article will use an easy-to-understand way to take you step by step how to judge how many cards Mahjong has won.

1. The basic card type structure of Mahjong Hu cards

In most Mahjong rules, the standard Hu card type consists of4 sets of faces (straight or carved) plus 1 pair of trump cardsComposition, a total of 14 cards. Face can be three consecutive straight (such as 1.23 million), or it can be three identical seals (such as three east winds). A general card is a pair of identical cards (such as two 5-barrel cards). When the cards in your hand can form such a structure, the basic conditions for a Hu card are met.

但很多新手会问：为什么我明明有4组面子加1对将牌，却还是不能胡？这通常是因为你忽略了胡牌张数的问题。所谓胡牌张数，指的是你听牌后，能够让你胡牌的那张牌有多少种可能。比如你听三六九万，那么胡牌张数就是3种（3万、6万、9万），每种可能还有剩余张数，需要结合牌河和已打出的牌来判断实际可胡的张数。

二、如何计算胡牌张数？

to judgeHow to think about how many cards Mahjong has?First of all, you need to make clear whether you have listened to the card. Playing cards means that you are only one card away from winning cards. After you listen to the cards, you can calculate the number of cards through the following steps:

  1. Determine the card listening type: Do you listen to a single sheet, listen to the opposite side, listen to the side, listen to the embedded sheet or listen to multiple sides? For different types of cards, the number of Hu cards varies greatly.
  2. List all possible cards: Based on your hand and card pool, list all the cards that allow you to form a Hupai card type.
  3. Calculate the number of remaining sheets：每种可能胡的牌，在牌墙和他人手中可能还有多少张。通常需要减去你已经看到的牌（包括自己手牌、牌河中的牌、碰杠的牌等）。

举个例子，如果你的手牌是123万、456万、789万、东东、5筒，那么你听的是5筒的单张。假设牌河中已经打出了2张5筒，你自己手中有1张5筒，那么剩余可胡的5筒只有1张（总共4张，减去3张）。这就是你的实际胡牌张数。

三、常见听牌类型的胡牌张数

The number of Hu cards varies greatly for different card types. Understanding these types will help you make quick judgmentsHow to think about how many cards Mahjong has?。

1. Listen to a single sheet

Only listen to one card, such as 1.23 million, 4.56 million, 7.89 million, Dongdong, 5 drums in your hand, only listen to 5 drums. The number of cards played in this kind of listening is usually small. If multiple cards have been played in 5 drums, there may be only 1 card or even 0 cards left, which is "dead listening".

2. 对倒听

Listen to two cards, but these two cards are the same pair. For example, you have 1.23 million, 4.56 million, 7.89 million, Dongdong, Nannan in your hand, listen to the east wind and the south wind. The number of cards played in this game depends on the appearance of Dongfeng and Nanfeng in the card river. If there is only one card left for both cards, then a total of 2 cards can be played.

3. Bian Zhang Ting

Just listen to side Zhang, for example, you have 1.23 million, 4.56 million, 7.89 million, Dongdong, 89 barrels in your hand, and listen to 7 barrels (7 barrels on the side). There is usually only one type of card for this kind of listening card, but there may be more cards left.

4. 嵌张听

Just listen to inlaid Zhang, for example, you have 1.23 million, 4.56 million, 7.89 million, Dongdong, 6 cylinders, 8 cylinders, and 7 cylinders (inlaid 7 cylinders) in your hand. There is also only one card to play.

5. 多面听

Listen to multiple cards, such as 1.23 million, 4.56 million, 7.89 million, Dongdong, 23456 cards in your hand, and listen to 1, 4, and 7 cards. This kind of card listening has a large number of cards and is an ideal type of card listening. Calculation for multi-faceted listening requires careful analysis of the card type to ensure that no cards that may be awkward are missed.

四、影响胡牌张数的因素

除了听牌类型，还有一些因素会影响How to think about how many cards Mahjong has?的结果：

  • 牌河中的牌：已经打出的牌会减少剩余可胡的张数。
  • 碰杠的牌：碰杠会暴露一些牌，同时也会改变牌墙的剩余牌数。
  • 其他玩家的手牌：虽然你看不到，但其他玩家手中的牌也会占用可胡的牌，需要根据他们的出牌推测。
  • 牌墙剩余牌数: The later the game reaches, the fewer cards remaining, but the fewer cards Hu may have.

Therefore, when judging the number of Hu cards, we cannot only look at the theoretical possible number, but also estimate it based on actual conditions. Experienced players will observe the river of cards and the opponent's playing habits to speculate which cards may still be in the wall.
