At the mahjong table, nothing is more exciting than "Tianhu". When the dealer finished playing 14 cards, he directly pushed down the announced Hu card. This card type, which almost only exists in legends, is the top lucky one in Mahjong-Tianhu. So,Playing Mahjong, Hu TianhuWhat does it mean? What are its rules? How low is the probability? This article will reveal you one by one.

What is Tianhu?

Tianhu, also known as Tianhe, is a special method of playing cards in mahjong. It means that after the dealer completes the card allocation, the starting 14 cards have already formed the card type, and there is no need to touch the cards or eat the bars and directly play the cards. Tianhu is the exclusive right of the Zhuang family. There are no Tianhu in idle families, only local or human Hu.

In most rules such as national standard Mahjong, Guangdong Mahjong, and Sichuan Mahjong, Tianhu is regarded as one of the card types with the highest number, and is usually counted as 88 times or directly capped. Because the probability is extremely low, once it appears, it often means the climax of the game and the player's extreme luck.

Tianhu's rules and conditions

To achieve Tianhu, the following conditions must be met at the same time:

  • Must be the dealer: Only the dealer has the opportunity to play 14 cards. The idle player only has 13 cards. You need to touch the first card to play, which is called a local card.
  • The starting card is the game: The 14 cards must have formed 4 pairs of faces (straight or cut) and 1 pair of general cards, or they must meet the seven-equivalent special card type.
  • No eating, touching, or biting behavior: Tianhu is a card completed purely by hand cards. Any side exposure will destroy the conditions of Tianhu.

It is worth noting that some local rules stipulate that if the dealer has a hidden bar in the starting hand, and then the card is used to make up the card, there is a dispute whether it is considered a tiger. The mainstream rule holds that the tiehu must be 14 direct tiehu from the beginning. After the card is crossed, the tiehu card is usually not counted as tiehu, but may be counted as other high-end card types.

How low is the probability of Tianhu?

The probability of Tianhu is one of the lowest among Mahjong events. Due to the extremely complex combination of mahjong tiles, the probability under different rules is slightly different, but it is generally believed that the probability of Tianhu isOne in a million to one in a millionbetween. Some players have calculated that in a standard 136-card mahjong, the probability of Tianhu is about 1/330,000, but considering various card types combinations, the actual probability may be lower.

This means that even if a player plays 100 games of Mahjong every day, it will take about 9 years to encounter Tianhu once. Therefore, Tianhu is regarded as a "miracle" in mahjong, and many players may not be able to experience it once in their lives.

The difference between Tianhu, Tianhu and Renhu

In addition to Tianhu, there are also ground hu and human hu in mahjong. They are both lucky card types that can be played immediately, but the conditions are different:

  • heavenly hand: The dealer plays 14 cards directly.
  • Dihu: The player starts with 13 cards. After the dealer plays the first card, the player will be a Hu card (or the player touches the first card and touches himself, depending on the rules).
  • Hu: The player starts with 13 cards. Before the first card draw, the cards played by other players will be played by him (i.e., the first round of shooting).

These three card types are extremely rare, among which the probability of Tianhu is the lowest, the second is the earth hu, and the human hu is relatively slightly higher, but it is still a very small probability event.

Tianhu's number in Mahjong rules in various places

The number of Tianhu varies according to regional rules, but it is generally extremely high:

  • National standard Mahjong: Tianhu counts 88 times, one of the highest times.
  • Guangdong Mahjong: Tianhu usually counts 10 times or directly caps, depending on the play method.
  • Sichuan Mahjong: Tianhu is generally regarded as the best and is usually directly slam.
  • Japanese Mahjong: Tianhu is at the end of his military service, ranking with the highest level of national scholars and Da Sanyuan.

No matter which rule, Tianhu means a huge victory for the game and can often reverse the winning or losing of the entire game.

What should I do if I encounter Tianhu?

If you are lucky enough to play a game at the table, you must first remain calm, make sure that your card type does meet the conditions for a game, and then push the card according to the rules to announce the game. Since Tianhu is extremely rare, it is recommended to take photos to commemorate it. This will be an unforgettable moment in the mahjong career.

For other players, meeting Tianhu can only lament their bad luck, but this is also the charm of Mahjong-always full of unknowns and surprises.
