Mahjong is one of the most popular board games in China, and its core goal is Hupai. But many novice players are often confused:How is Mahjong considered a game?？In fact, the basic conditions for Hu cards are not complicated. As long as you master the card structure and key points of the rules, you can easily judge them. This article will combine the mainstream mahjong gameplay in 2026 to provide you with a detailed breakdown of Hu's standards and techniques.

1. Basic conditions for Hu Pai

In most mahjong rules, Hu cards need to meet two basic conditions: first, the number of cards in the hand reaches the specified number of cards (usually 14, including touching or eating cards after touching the bar), and second, the card type conforms to a specific combination structure. Simply put, the hand must be played byFour sets of faces (straight or carved) plus a pair of trump cardsComposition, or conform to special card types (such as seven pairs, thirteen ones, etc.).

1. 面子与将牌的定义

There are two types of face:shunzi（同花色连续的三张牌，如1万2万3万）和pung（三张相同的牌，如三个东风）。将牌则是一对相同的牌，如两个5筒。一副标准的胡牌牌型通常是“4面子+1将”，共14张牌。

2. Calculation of the number of cards when Hu is playing

It should be noted that if the player forms a secondary display (open card) by eating, touching, and bars, the number of cards in the hand will decrease accordingly. For example, after touching a set of cards, there are only 10 cards in your hand, but if you add the 3 cards exposed, the total number of cards is still 13 cards (while waiting for the card to be played), and when the card to be played, one more card is inserted to form 14 cards. Therefore, judging Hu cards cannot only be based on the number of cards in the hand, but also based on the exposure situation.

Dampenhu required that all four groups of face be carved (or bars) and no straight. For example:

  • Hand: three 10,000 cards, three 5,000 cards, three dongfeng cards, three 9,000 cards, a pair of 80,000 cards (general cards)

3. Guangdong Mahjong

日本麻将（立直麻将）要求胡牌必须有“役”（番种），且不能有“振听”情况。此外，日本麻将中“宝牌”不计算为役，只增加番数。
