In actual Mahjong combat, poker is a common operation, and poker behind the bar is the goal pursued by many players. So,How many pieces did you play mahjong?？This question may seem simple, but in fact it involves differences in different mahjong rules. This article will analyze the calculation of the number of cards behind the bar in detail to help you become more comfortable at the table.

The basic concept of the card behind the bar

Bar cards are divided into three types: open bar, hidden bar and additional bar. After the card is stacked, the player needs to make up a card from the end of the card wall. This card is called a "card on the bar". If this card on the bar just happens to make you play, it is called "blooming on the bar". Blooming on the bar usually has an extra number of rewards, but the number of Hu cards is calculated the same as that of ordinary Hu cards.

Number of ordinary Hu cards

In most Mahjong rules, the basic card type of Hu is14 cards, which consists of 4 sets of faces (straight or carved) and 1 pair of trump cards. After the cards are tied, the total number of cards in the hand will increase because the cards occupy 4 cards but are only counted as one set of faces. Specifically:

  • Bright bars: There is a set of bright bars in the hand, and the total number of cards is 14+1=15 (because the 4 cards of the bright bars count as a set of faces, but one card needs to be replenished from the card wall, the number of cards in the hand becomes 15 cards, but the actual effective card type is still a 14-card structure).
  • Dark bars: There is a set of dark bars in the hand, and the total number of cards is 14+1=15. However, the 4 cards of the dark bars are not bright and are still counted as the hand. Therefore, the actual number of cards in the hand is 15, but the card must comply with the 14-card structure.
  • Add bars: Add bars on the basis of existing cards, and the total number of cards will also increase by 1 card.

Therefore, when cards are played behind the bars, the total number of cards in the hand is usually 15 or more, but the effective card type is still a 14-card structure. For example, if you have a hidden bar and there are 3 sets of faces and 1 pair of generals in your hand, then the total number of cards is 15, but when dealing with cards, you only need to satisfy 4 sets of faces +1 pair of generals.

Differences in different Mahjong rules

Mahjong rules in different regions have slightly different calculations of the number of cards behind the bars, mainly reflected in whether the bars are counted as face and whether special card types such as "flowers on the bars" are allowed.

National standard Mahjong

In national standard mahjong, cards are replenished after the bar. If the card is played, the flowers on the bar will be added 8 times. The number of Hu cards is still in the structure of 14 cards, and the bars are counted as a set of face. For example, if you have a clear bar and there are 3 sets of face cards and 1 pair of general cards in your hand, the total number of cards is 15, but the effective card type of Hu cards is 14.

Sichuan Mahjong

Sichuan Mahjong is popular in "bloody battles to the end". Cards are replaced after the cards are used. If the cards are used, they are called "flowers on the bars" and added 1 times (or more). In Sichuan Mahjong, the number of cards in hand after the bar card increases, but the basic card type still needs to be satisfied when playing cards. It should be noted that in Sichuan Mahjong, there are extra points for "windy and rainy" bars, but the number of Hu cards remains unchanged.

Guangdong Mahjong

In Guangdong Mahjong, cards are replenished after the bar. If the card is played, it is called "blooming on the bar" and is usually added three times. The number of Hu cards is also 14 cards. In Guangdong Mahjong, the number of cards in hand after the bar card may exceed 14, but only the basic card type is required when playing cards.

Special circumstances of Hu card behind the bar

In some special card types, the number of cards behind the bar may be different. For example, in the seven-pair card type, if there are bars, it cannot be counted as seven pairs, because the bars occupy 4 identical cards and cannot form 7 pairs. Therefore, the seven pairs of Hu behind the bar are not valid.

In addition, in special card types such as the "Thirteenth One", bar cards are usually not allowed, because the Thirteenth One requires one card each of the 13 types of 19 cards, and bar cards will destroy the card type.

How to calculate the number of cards behind the bar

To accurately calculate the number of cards behind the bar, you can follow the following steps:

  1. Determine the type of bar card: open bar, hidden bar or additional bar.
  2. Calculate the total number of cards in your hand: basic 14 + the number of cards added to the bar (1 card added to each bar).
  3. Check the card type structure: Ensure that in addition to the bars, the other cards in the hand can form 3 sets of face cards and 1 pair of general cards (or conform to a special card type).
  4. Confirm the number of cards: The effective card type is still 14 cards, but the actual number of cards in the hand may be 15 or more.

For example, if you have a hidden bar (4 cards), and there are also 2 sets of straight (6 cards), 1 set of carved cards (3 cards), and 1 pair of generals (2 cards) in your hand, then the total number of cards is 4+6+3+2=15 cards, but the effective card type of Hu cards is 14 cards (the hidden bar counts as a set of faces, and the remaining 3 sets of faces +1 pair of generals).

summary

To sum up,How many pieces did you play mahjong?？The answer is: When cards are played behind the bars, the total number of cards in the hand is usually 15 or more, but the valid card type is still a 14-card structure. Different mahjong rules reward different numbers of games behind the bars, but the requirements for basic card types are the same. Mastering the calculation of the number of cards behind the bar will help you better judge the card type and make decisions in actual combat. I hope this article can help you improve your mahjong skills and enjoy the fun of blooming on the bars!
