In Mahjong, the most exciting moment is to push down the cards and shout "Hu". But many novice players are often confused:How to calculate when Mahjong is too bad?？In fact, the calculation of Hu cards involves two levels: one is to determine whether the basic card type of Hu cards is satisfied, and the other is to calculate the number or score based on the card type and rules. This article will break down in detail for you to easily master.

1. Basic conditions for Mahjong

No matter what kind of mahjong play, Hu Pai must satisfy one core structure:Four sets of faces plus a pair of trump cards(Commonly known as "4 faces and 1 bird head"). Face can be a straight (such as 1.23 million) or a cut (such as three east winds), and a general card can be a pair of the same cards. In addition, some rules also require at least one (such as national mahjong) or one must be missing (such as Sichuan mahjong).

1. Shunzi and Kezi

A straight is composed of three consecutive cards of the same suit, such as the "456 barrel"; a cut is composed of three identical cards, which can be the open cut drawn out or the secret cut in the hand. Bar cards (four identical) are usually counted as a set of faces when playing cards, but the specific handling method varies depending on the rules.

2. Jiangpai (Sparrow Head)

The trump card is the only pair when playing the card and cannot be part of a straight or a cut. For example, if there are two "red midges" in the hand, they can be used as trump cards. It should be noted that some rules have special requirements for generals, such as "generals cannot be cards" or "258 must be used as generals."

2. Common Hu card types and calculations

After understanding the basic conditions, let's take a lookHow to calculate when Mahjong is too bad?Fan. Fan is a unit for measuring the size of Hu cards. Different card types correspond to different numbers of fans. Here are a few common brand types:

  • pinghu: It is all composed of straight runs, no engraved pieces, and the trump card is not a word card. Usually 1 times.
  • Pengpenhu: All consists of carved pieces (or bars), no straight. Usually twice or higher.
  • exclusively: All cards in your hand are composed of one suit (excluding the cards). Usually 6 or 8 times.
  • seven pairs: The hand consists of seven pairs, with no straight or cut. Usually 4 or 7 times.
  • mixed color: Consists of a suit and a sign. Usually 3 or 5 times.

In addition, there are special card methods such as "blooming on the bar","fishing for the moon at the bottom of the sea" and "grabbing the bar", which add extra times to the basic number.

3. Detailed steps for calculating numbers

To accurately calculate the number, you can follow the following steps:

  1. Determine the basic card type: Judge which one of the cards is flat Hu, touch Hu and seven pairs, and get the basic number.
  2. Check additional conditions: Whether there are clear doors (do not eat or touch unknown bars), self-touching, blooming on bars, fishing for the moon under the sea, etc. These are usually added once or more.
  3. Calculate special card types: If it conforms to uniform color, mixed color, character color, etc., it will be calculated according to the corresponding number of times. Usually, these numbers are higher and the number of times of the basic card type is no longer superimposed.
  4. Add all the numbers: Add the basic number and the additional number to get the total number. Some rules have cap limits, such as a maximum of 8 times or 16 times.

For example, in the national standard mahjong, Hu has a card of "all-color + touching Hu + self-touching", and the number of times may be: all-color 24 times + touching Hu 6 times + self-touching 1 time =31 times, but the national standard has a cap of 88 times, so the actual calculation is based on 88 times.

4. Differences in rules in different regions

It should be noted thatHow to calculate when Mahjong is too bad?There are significant differences in different regions. For example:

  • Sichuan Mahjong: Usually, you can only get rid of "one door" and there is no sign. The calculation of the number is relatively simple. Common ones include "root"(four identical),"flower on the bar", etc.
  • Guangdong Mahjong: Concepts such as "chicken beard","Pinghu" and "explosive beard" are popular. The calculation of the number is complex, and there are big names such as "Nine Children Connected" and "Thirteen One".
  • National standard Mahjong: There are 81 species, with a maximum of 88 species. The calculation is the most standardized and suitable for competition.

Therefore, it is best to understand the local rules before playing to avoid disputes due to different algorithms.

5. Practical skills: quickly estimate the number

For beginners, master the following techniques to make faster calculations:

  • Remember the benchmark number of common card types, such as 1 Pinghu, 2 Pinghu, 6 Pinghu, etc.
  • Pay attention to special bonus items: self-touching, blooming on the bar, fishing for the moon in the sea, grabbing the bar, etc. are usually added once each.
  • If the card type satisfies multiple large categories at the same time, the highest one will be calculated and not superimposed repeatedly.

Anyway,How to calculate when Mahjong is too bad?It is not mysterious. As long as you are familiar with the basic rules and common recipes, you will be able to respond quickly with more practice. I hope this article can help you become a master of arithmetic on the mahjong table!
