On the mahjong table, you will occasionally hear someone exclaiming,"God!" Have you been playing mahjong all day? This is a question in the hearts of many mahjong enthusiasts. Tianhu is one of the most difficult card types in mahjong. Not only is the probability extremely low, but it is also often endowed with various mysterious colors. This article will reveal the veil of Tianhu for you from the perspectives of rules, probability, and cultural implications.

What is Tianhu?

Tianhu, also known as Tianhe, refers to the situation where the dealer directly draws the cards after starting to match the cards without any operations such as drawing, eating, touching, or holding cards. To put it simply, when the dealer gets the initial 14 cards, the card type has been formed. In most Mahjong rules, Tianhu is regarded as one of the highest species, and is usually listed as the "Three Talents Hu" along with the ground Hu and the human Hu.

Tianhu's rules require

  • It must be the dealer: Only the dealer has a chance to play the game, because the dealer has one extra card (14 cards) at the start, and the idle player only has 13 cards.
  • No action was taken: After starting, directly play cards, and no behaviors such as eating, touching, or mending.
  • Complete card type: Must conform to the basic card structure, such as four straight or carved cards plus a pair of generals, or special card types such as seven equal.

How low is the probability of Tianhu?

The probability of Tianhu is extremely low, making it a "miracle" in mahjong. According to mathematical calculations, among the standard 136 mahjong cards, the probability that the dealer's starting 14 cards exactly form a Hu card type is approximately1/330,000left and right. This means that even if you play 100 games of Mahjong every day, it may take nearly 10 years to encounter Tianhu once. So, have you been playing mahjong all day? From a probability perspective, this is undoubtedly an extremely lucky event.

Factors affecting the probability of Tianhu

  2. Hustle rules: Some rules allow special card types (such as seven pairs, thirteen ones, etc.), which may slightly increase the probability of hustle.
  3. Starting hand quality: If the starting hand is close to a Hu hand, the probability of a Hu hand will increase relatively, but the overall situation is still extremely low.
