At the mahjong table, there is an amazing luck called "Playing Mahjong will make it difficult", which is what we often call" Tianhu ". For many mahjong enthusiasts, the initial 14 cards are directly tied, which is simply a miracle that can only be encountered and cannot be sought. So, how difficult is Tianhu? What are the rules and probabilities behind it? Today we will discuss in depth this top lucky event in Mahjong.

What is Tianhu? Analysis of the rules of playing at the start of the card

Tianhu, also known as "Tianhe", means that after the dealer has completed the allocation of cards, before the first card is played, the cards in his hand have formed a Hu card type, thus directly announcing the draw. In most mahjong rules, Tianhu is regarded as one of the highest number of games. For example, the national standard mahjong Zhongtian Hu is 88, and the Japanese mahjong is full number of games. It should be noted that Tianhu is only applicable to the banker. The situation where an idle player starts playing a game is often called "Di Hu"(the first card played by the idle player is playing a game) or "Ren Hu"(the idle player plays a card played by others during the first tour).

Tianhu's fulfillment of conditions

  • Must be the dealer, with 14 cards starting from the start (including the first card drawn after dealing).
  • The cards in the hand do not need to eat, touch, or bar, and directly satisfy the Hu card type (usually 4 pairs of faces +1 pair of generals, or 7 pairs of equal special card types).
  • No exposure (eating, touching, exposed) or hidden exposure was performed.
