Sichuan Mahjong is famous for its unique "bloody battle to the end" and "missing door" rules, but many novices and even veterans are often confused:What cannot be done in Sichuan Mahjong?？In fact, situations where you cannot play are mainly divided into two categories: one is because the card type does not meet the basic playing conditions, and the other is because you are prohibited from playing because you violate specific rules. This article will combine the latest popular gameplay in 2026 to disassemble you one by one to avoid you stepping on the poker table.

1. Basic conditions for cards: missing doors and card type restrictions

The core rule of Sichuan Mahjong isOne must be missing, that is, when playing cards, there can only be two suits (ten thousand, tube, and bar) in the hand, and one of them must be missing. If there are all three colors in the card hand, called "piggy", not only will you not be able to play the card, but you will also have to pay for it. Therefore, in the process of playing cards, it is necessary to determine the shortage as early as possible to avoid being passive in the later stage.

In addition, Sichuan Mahjong usually requiresDon't take cards，只能碰、杠，且胡牌牌型必须符合基本结构：4副顺子或刻子（或杠）加1对将牌，或者特殊牌型如七对、清一色等。如果牌型不完整，自然不能胡。

2. Failure caused by special rules

1. Chajiao (Chahua Pig)

In the "bloody battle to the end" gameplay, when no one plays after touching the card wall, the "check" stage is entered. At this time, all players who have not listened to the cards (i.e.,"pig pigs") will compensate the players who have listened to the cards, andThose who have not listened to the cards cannot play the cards。Even if you have cards in your hand that you can play, you cannot play if you have not called (listening to the cards). Therefore, calling as early as possible is the key to avoiding losses.

2. Pass water (pass Hu)

In Sichuan Mahjong, if you can already play a certain card but choose not to play (crossing the water), then in the same circle, you cannot play the same card played by other players. You must wait until you draw the card before you can restore the play. Otherwise, the system will determine that you are "not successful" and cannot play cards. This is a detail that many players ignore.

3. xianggong

If the number of cards in your hand is wrong due to operational errors (such as touching too much, touching too little, touching wrongly, etc.) and you become a "husband", then the Council cannot play tricks and can only play with you. So be extra careful when playing cards to avoid husbands.

4. Restrictions on specific card types

In some Sichuan Mahjong games, certain special card types may be prohibited, such as:

  • "All requests" restriction: Some rules do not allow asking for all cards (that is, all cards are touched or picked up, and one card is finally hung), or require you to touch yourself.
  • "Fishing for the Moon in the Sea" restriction: Some rules stipulate that the last card cannot be played, or you can only play yourself but not click.
  • “杠上花”限制: Some rules do not allow flowers on bars, or flowers on bars must be touched by yourself.

These restrictions vary by region or platform, and it is best to confirm them clearly before starting.

3. Common misunderstandings: Which card types seem to be able to play but are not?

Many players have misunderstandings about "what should not be done in Sichuan Mahjong?" The following are a few typical misunderstandings:

  • Misunderstanding 1: You can mess with each other。Having more bumps does not mean that the card type is complete. It must meet the structure of 4 + 1 players, otherwise it cannot be played.
  • Misunderstanding 2: If you are missing, you will be able to succeed。Missing a goal is only a necessary condition, not a sufficient condition. If the card type is wrong, you can't play hard.
  • Myth 3: You can play any card after listening to the card。After listening to the cards, you can only play the few cards you listen to. If the cards played by others are not within your listening range, you cannot play.
  • Myth 4: Self-touching is not restricted。Self-touching must also meet the requirements of missing doors and card types, and self-touching by a pig is also ineffective.

4. Analysis of actual combat cases

Case 1: Player A's hand has 4 cards, 4 cards, and 4 cards each. There are no missing cards. At this time, someone plays the cards A needs. Can A play?cannot, because A is a flower pig, he must be short of one class before he can succeed.

Case 2: Player B has already listened to the cards and listened to 50,000 and 80,000. The previous player plays 50,000. B chooses not to play (crossing the water), and then plays 50,000. Can B play?cannot, because you cannot play a card in the same circle after crossing the water, you must wait until you draw the card before you can recover.

Case 3: Player C has all cards in his hand, but the card type is 7 straight and 2 generals, making a total of 9 cards. Can he play?cannot, because the number of cards is wrong, 14 cards are required for all cards (or reduced accordingly after touching the bar), and the structure must be complete.

5. How to avoid embarrassment?

1. Identify vacancies as early as possible：开局根据手牌情况，果断定缺，避免后期花猪。

2. 注意过水规则: If you don't play a card, you must remember that you can't play another card in the same circle. It's best to wait until you draw your own cards before making a decision.

3. Keep the card count correct: Check the number of cards in your hand after touching, touching, and holding cards to avoid cheating.

4. Be familiar with local rules: Different regions or platforms have different restrictions on special card types, so understand them clearly before the start to avoid problems caused by differences in rules.

Anyway,What cannot be done in Sichuan Mahjong?, the core lies in the rules such as lack of door, card type, water passing, and harmony. By mastering these, you will be able to work at the table, reduce mistakes, and enjoy the fun of mahjong.
