In mahjong games, the moment players most look forward to is to successfully play after listening to the cards. But have you ever encountered a situation where you have already listened to the cards and even touched a card that seems to be able to play, but you are told by other players that "this card cannot be played"? This is the "no Hu" rule in Mahjong. So,Which card in Mahjong cannot be played?？In fact, this does not refer to a specific card, but is determined by a variety of rules and situations. Understanding these ban rules will not only avoid embarrassment, but also improve your mahjong strategy.

Common rules for banning Hu: Under what circumstances cannot Hu be Hu

Mahjong's ban rules vary depending on the region, but the following situations are common in most rules:

  • Don't go through the water: If you have already listened to the cards, but you have not played the cards played by others (whether intentionally or unintentionally), then in the same circle, if other players play the same cards again, you cannot play the same cards. You must wait until you draw the cards (or the next round) before you can restore the right to play the cards. This is to prevent selective hoarding.
  • Punishment for cheating: If you shout Hu without a real Hu card, it is a fraud. Not only can you not play Hu, you must also accept punishment. But this is not "which card cannot be played", but a behavioral error.
  • Special card type restrictions: Some special card types such as the "thirteen and one" may require you to play yourself and not play cards played by others; or the "seven pairs" may not be allowed to play cards under certain rules.
  • Limit on the number of cards remaining on the card wall: Some rules stipulate that the last few cards of the card wall (such as the last four cards) cannot be played and can only be played.

Prohibition of specific cards: from "cards that cannot be played" to "card types that cannot be played"

Strictly speaking,Which card in Mahjong cannot be played?If this problem is understood as "a specific card cannot be played", it usually does not exist. Any card can be played when it matches the type of play. However, there are some "can't play cards" or "can't play situations":

1. Card type that cannot be played: does not conform to the basic card structure

The basic structure of Mahjong Hu tiles is usually four pairs of straight or carved pieces plus a pair of generals (there are other requirements for national mahjong). If the cards in your hand cannot form such a structure, no matter what cards you touch, you cannot play. For example, if you have 13 cards in your hand, but you are missing one card, or if the card types are chaotic, no one card will allow you to win. In this case, if you are in a state of "not listening to cards", you naturally cannot play any cards.

2. Cards that cannot be played: Specific cards prohibited by rules

In some local rules, there are indeed situations where certain cards cannot be played:

  • "Laizi card" cannot be played: In the gameplay with razi (universal card), the razi card itself usually cannot be used as the card of the Hu card, but can only be used as other cards. For example, if the red medium is a leash, you cannot muddle the red medium unless the red medium is not used as a leash (but general rules do not allow it).
  • "Treasure cards" cannot be spoiled: Similar to Laizi, treasure cards cannot be directly played out under certain rules.
  • The "last card" cannot be played: Some rules stipulate that the last card on the card wall cannot be played. If you touch it, you must be played, otherwise the game will flow.

Prohibition rules for special brand types

In addition to the above circumstances, some special brand types also have rules prohibiting Hu:

1. Thirteenth one (unparalleled national scholar)

The thirteen ones are a typical special card type, consisting of one card for each of the thirteen ones and nine cards plus any one. In most rules, you can play the cards played by others on the 13th, but in some places it is stipulated that you must play yourself. In addition, if the card played by others is the 19th card you already have, you cannot play because the 13th card requires one card for each type of 19th card and cannot be repeated. For example, if you already have an east wind and others are playing another east wind, you can't take advantage of this east wind because a pair will be formed, which does not match the thirteen-one card type.

2. seven pairs

Seven pairs are cards composed of seven pairs. In most rules, seven pairs can play cards played by others. However, some rules stipulate that seven pairs cannot grab the card (that is, you cannot grab the card when others add the card). In addition, if a seven-pair contains four identical cards (i.e. two pairs), some rules do not recognize this "luxury seven-pair", resulting in inability to play.

3. Not at all (13)

All Don't rely on is a special brand type, consisting of a single sheet of southeast, northwest, middle hair white, 147, 258, 369, etc. This type of card can usually only be played by yourself and cannot play the cards played by others, because it is difficult for others to judge whether you are listening to the cards and can easily cause controversy.
