Fuzhou Mahjong is a popular mahjong game in Fujian. Its unique rules and points calculation methods often confuse novices. In particular, the question of "how to calculate a Hu" involves many aspects such as Hu card conditions, card type combinations, and number calculation. This article will provide you with a detailed breakdown of Fuzhou Mahjong's Hupai rules and scoring methods, so that you can easily get started.

1. The basic conditions for Fuzhou Mahjong and Hu cards

在福州麻将中，胡牌需要满足一定的牌型结构。通常，胡牌牌型由四副顺子或刻子（或杠）加上一对将牌组成，即“4组+1对”的基本结构。此外，福州麻将还有一些特殊规则：

  • One must be missing：胡牌时，手牌中不能同时包含万、条、饼三种花色，必须缺少其中一种。
  • Don't take cards：福州麻将不允许吃牌，只能碰牌和杠牌，这增加了胡牌的难度。
  • 有番才能胡: Some Fuzhou Mahjong rules require that a card must reach a certain number of times (such as at least 1 times), otherwise you cannot play a card.

2. Common Hu card types and scoring of Fuzhou Mahjong

福州麻将的算分通常以“底分”为基础，根据胡牌牌型的番数进行倍数计算。以下是几种常见的胡牌牌型及其算分方式：

1. pinghu

平胡是最基本的胡牌牌型，由四组顺子或刻子加一对将牌组成，没有特殊牌型。平胡通常算1番，即底分×1。例如，底分为1分，则平胡得1分。

2. Pengpenhu

碰碰胡是指胡牌时，四组牌全部是刻子（或杠），没有顺子。碰碰胡通常算2番，即底分×2。如果底分为1分，则碰碰胡得2分。

3. exclusively

清一色是指胡牌时，手牌全部由同一种花色组成（万、条、饼中的一种）。清一色通常算4番，即底分×4。如果底分为1分，则清一色得4分。

4. mixed color

Mixed color means that when playing cards, the hand consists of one color plus the word cards (white in the southeast, northwest and middle). Mixing one color is usually counted as 2 times, that is, base points ×2.

5. seven pairs

Seven pairs refer to the case of Hu cards, the hand consists of seven pairs, with no straight or cut. Seven pairs are usually counted as quadruple, i.e., base score ×4.

6. flower on the bar

Blooming on the bar means that the player plays cards after drawing cards after the bar. Blooming on the pole is usually added to the number of rounds of the original card type. For example, blooming on a flat hu bar is twice.

7. 抢杠胡

抢杠胡是指其他玩家在加杠时，玩家可以胡那张杠牌。抢杠胡通常算1番，并且被抢杠的玩家需要支付三家的分数。

3. Fuzhou Mahjong Special Points Calculation Rules

In addition to the basic card type number, Fuzhou Mahjong also has some special scoring rules that require special attention from players:

  • Self-touching Kafan: When playing your own card, you will usually add 1 time to the original number. For example, Pinghu calculated himself twice.
  • Menqing Jiafan：门清是指胡牌时没有碰牌、杠牌（暗杠除外），保持手牌未亮明。门清通常加1番。
  • 中发白刻子加番：如果手牌中有中、发、白的刻子（或杠），每个刻子加1番。
  • 坐庄翻倍：庄家胡牌或点炮时，分数通常会翻倍。具体倍数根据规则而定，常见为2倍。

4. Analysis of Fuzhou Mahjong Points Calculation Example

To help you understand better, let's take a look at a specific example of scoring:

Suppose that the bottom score is 1 point, and Player A plays his own card, the card type is uniform, and the door is clear, and there are no other special card types. Then:

  1. All colors: 4 times
  2. Self-touching: Add 1
  3. Door Qing: Add 1

Total number of times = 4 + 1 + 1 = 6 times. So, player A deserves points = base points × 2^(number-1)? Note: Fuzhou Mahjong score calculation formulas may be different in different regions. Common ones are "base score × frequency" or "base score ×2 to the power of (frequency-1)". In this paper, we adopt a simple algorithm of "base score × number", that is, 6 points. If a multiple algorithm is used, the score will be higher.

In actual games, please follow local rules.

5. Fuzhou Mahjong Hu Card Skills and Precautions

掌握算分规则后，还需要一些实战技巧来提高胡牌效率：

  • 优先做清一色或混一色：由于番数较高，可以快速提升得分。
  • 注意缺一门：尽早确定要缺的花色，避免后期无法胡牌。
  • Reasonable use of collision bars: Touching a bar can change the card type, but it will also expose information, so you need to be cautious.
  • observe the opponent: Estimate your opponent's hand through his cards and avoid firing shots.
