Mahjong is one of the most popular chess and board games in China. The rules vary widely from place to place, but it remains the same. The most common question asked by many novice players is:How can national Mahjong be considered ridiculous?？其实，无论哪种地方玩法，胡牌的核心逻辑都是一致的。本文将以通用规则为基础，结合主流地方麻将的共性，为你彻底讲清楚胡牌的条件和牌型。

1. Basic conditions for Hu Pai

简单来说，胡牌就是你的手牌（包括摸牌或别人打出的牌）组成了符合规定的牌型。在绝大多数麻将规则中，胡牌必须满足以下两个条件：

  • Card type complete structure: It usually consists of four sets of faces (straight or carved) and a pair of general cards, for a total of 14 cards. Except for a few special card types such as seven pairs and thirteen ones.
  • Comply with rules and restrictions: For example, there must be no lack of doors (some rules require "19" or "sign"), there must be no illegal "flower sign", etc.

只要同时满足这两个条件，就可以宣布胡牌。当然，具体到每个地方，还会有一些额外的限制，比如四川麻将必须缺一门，广东麻将要求有番等。

二、基本胡牌牌型

The most classic Hu card type is "4 faces +1 generals", which is also the basis of most mahjong teaching. Face is divided into straight and carved:

  • shunzi: Three cards of the same suit and consecutive numbers, such as "10,000, 20,000, 30,000".
  • pung: Three identical cards, such as "three east winds" or "three five cards".
  • trumps：一对完全相同的牌，如“两个红中”。

例如，你的手牌为：123万、456条、789筒、三个东风、一对发财，这就是标准的胡牌牌型。需要注意的是，顺子只能由同一种花色的牌组成，不能跨花色。

3. Special Hu brand type

In addition to basic card types, many places also allow special card types, which often have higher numbers or more relaxed conditions. Common special brand types include:

1. seven pairs

手牌由七个对子组成，共14张牌，不需要顺子或刻子。例如：一对一万、一对三万、一对五条、一对七条、一对九筒、一对东风、一对红中。七对在多数规则中都是允许的，且番数较高。

2. Thirteenth one

由十三种幺九牌（一万、九万、一条、九条、一筒、九筒、东南西北中发白）各一张，再加上其中任意一张组成对子。这是非常罕见的牌型，番数极高。

3. exclusively

全部手牌由同一种花色的牌组成，没有字牌和其他花色。例如全部是万子，或者全部是条子。清一色通常需要缺门，但番数很高。

4. 碰碰胡

由四个刻子（或杠）加一对将牌组成，没有顺子。例如三个东风、三个五万、三个七条、三个九筒、一对发财。碰碰胡也较为常见。

4. Differences in the Hu Cards of Mahjong in Different Regions

虽然基本逻辑相同，但各地麻将的胡牌规则仍有显著差异。了解这些差异，才能避免在牌桌上闹笑话。

Sichuan Mahjong

Sichuan Mahjong must be missing one door, that is, there cannot be three colors in the hand at the same time, usually only two colors can be available. When playing cards, you can't take cards, you can only touch and stick. In addition, Sichuan Mahjong has no word plates or flower cards, and the number of cards is small.

Guangdong Mahjong

Guangdong Mahjong usually requires a certain number of plays, such as chicken mugs, flat mugs, and explosive mugs. The calculation of the number is complex and involves flowers, bars, door style carving, etc.

National standard Mahjong

国标麻将规则统一，有81个番种，胡牌必须达到8番以上。它允许吃、碰、杠，但牌型组合更加多样，适合竞技比赛。

5. Common misunderstandings and matters needing attention

很多新手在判断是否胡牌时容易出错，以下是一些常见误区：

  • 误以为顺子可以跨花色：顺子必须同花色，如“一万、二万、三万”可以，但“一万、二条、三筒”不行。
  • 忽略将牌的要求: The basic card type must have a pair of trump cards, not a single card. If you only have four sets of face and no trump cards, you can't play.
  • Confusion of "listening cards" and "Hu cards"：听牌是差一张就能胡的状态，但只有摸到或别人打出那张牌才能胡。
  • 忘记特殊牌型的限制：例如七对不能有重复的对子（即不能有四个相同的牌），十三幺必须包含所有幺九牌等。

此外，在实战中还要注意“诈胡”的严重后果。诈胡是指不符合胡牌条件却宣布胡牌，通常会被罚分或赔钱。因此，在喊胡之前一定要仔细检查自己的牌型。

六、如何快速判断能否胡牌

对于新手来说，快速判断胡牌可能有些困难。这里提供一个简单的步骤：

  1. Number of cards counted first: Is it 14 cards (or 14 cards after drawing cards)?
  2. Try grouping: Divide your hand into four groups of face cards and a pair of trump cards to see if it is feasible.
  3. 检查特殊牌型：如果基本牌型不成立，再看是否满足七对、十三幺等特殊牌型。
  4. 核对规则限制：确认是否缺门、是否有番、是否允许吃碰等。

多加练习后，你就能在几秒内判断出是否胡牌。记住，How can national Mahjong be considered ridiculous?的核心就是“结构完整+符合规则”，掌握了这一点，无论走到哪里都能轻松应对。
