In Mahjong games, many players have encountered such confusion: they have clearly listened to the cards or even touched the cards themselves, but they are judged to be "unable to play". This is often because the card type does not comply with the basic rules of Hu cards, or it encounters certain special restrictions. So,Which type of mahjong can not play？This article will analyze in detail several common card types that cannot be played to help you avoid getting confused at the table.

1. Review of the basic Hupai rules

Before delving into the card types that cannot be played in depth, let's briefly review the basic playing conditions of mahjong. Generally speaking, the standard Hu card type needs to satisfy the structure of "4 sets of faces +1 pair of generals", that is, four pairs of straight or chips (bars are also counted as chips), plus a pair of identical cards as trump cards. In addition, there are special card types such as seven pairs. If the card type does not conform to these basic structures, naturally it cannot be played.

2. Common card types that cannot be played

1. Wrong number of cards

The most basic mistake is the wrong number of cards. When playing cards, you must have 14 cards in your hand (including cards from eating, touching, and behind the bar). If you have one more card or one less card, you will not be able to play cards. For example, if someone touches a card but forgets to play one, causing the hand to become 13 or 15 cards, no matter how good the card type is, it cannot be played.

2. Incomplete structure

Even if the number of cards is correct, if you cannot form a structure of 4 sets of face +1 opponents, you cannot play. For example, if you have three identical cards (cut cards) and two identical cards (generals) in your hand, but the remaining cards cannot form a straight or cut card, there will be a situation of "no trump" or "one less group". For example: 1.23 million yuan, 456 yuan, 789 yuan, East, East, South, and Central. There are only three sets of faces and a pair of generals here. If one set of faces is missing, you cannot be arrogant.

3. Does not meet the requirements of special brand type

Some local rules allow special card types, such as seven pairs, thirteen ones, and none. These brand types have strict composition requirements. If they do not meet the requirements, they cannot be used. For example, seven pairs require seven pairs of cards in the hand. If one pair is knocked down or there is an extra slot, seven pairs cannot be formed. On the 13th, one needs to collect one card and one card each of 13 types of 19th cards and one card, and add any card to form a pair. You cannot play without any of them.

4. Card types that violate the "Hu Card Ban"

In some rules, some card types are prohibited from playing cards even if they are structurally complete. For example, in national standard mahjong,"asking for all" must be a single fishing player by eating, touching, and exposing, and there must be no secret carving; if there is a secret carving in the hand, it cannot be regarded as asking for all. Another example is that "cannot be pushed down" requires all cards to be centrically symmetrical. If non-centrically symmetrical cards are mixed in, they cannot be played. In addition, some local rules stipulate that the "chicken beard"(that is, the smallest flat beard) cannot be played and must have a number. At this time, if the card type does not have a number, even if the structure is correct, it cannot be played.

5. The card type of fraud

Hug fraud refers to a player announcing a hug when he does not meet the hug conditions. This is usually due to a wrong card or a wrong calculation of the structure. For example, if four identical cards are regarded as two pairs, but in fact only one pair is left after the card is tied, resulting in a structural error; or if the straight is mistaken, for example, 1, 2, and 40,000 are regarded as 1, 2, and 30,000. Not only can you not cheat, but you may also be punished, so you must carefully confirm the card type.

3. How to avoid card types that cannot be played

To avoid card types that cannot be played, you must first be familiar with the local mahjong rules, including basic card structure, special card types, number requirements, etc. Secondly, when listening to cards, you should carefully calculate your cards to ensure that you can form an effective Hu card type. Finally, before announcing Hu cards, it is best to check the cards in your hand again to avoid cheating Hu cards due to negligence.
