In the world of mahjong, nothing is more exciting than playing cards at the beginning, especially when you touch a good hand and directly declare "Tianhu". The so-called Tianhu refers to the fact that after starting to match the cards, the dealer directly reaches the card type without any operations such as drawing, touching, or holding cards. This card type is extremely rare and can be called the "chosen game" in mahjong. So, how low is the probability of switching mahjong Zhongtian Hu? How should players seize this once-in-a-lifetime opportunity? This article will analyze it one by one for you.

How low is the probability of switching Mahjong Tianhu?

The probability of Tianhu has always been a hot topic in the mahjong world. Since the rules for transferring mahjong are different from national standard mahjong and Sichuan mahjong, the probability of playing games will also be affected by factors such as the number of cards and the type of playing cards. Generally speaking, the probability of Tianhu is extremely low, ranging from one in a few hundred thousand to one in a million. Specific to turning mahjong, if 136 cards (excluding flower cards) are used and the dealer starts with 14 cards, they need to directly form the Hu card type, and the number of combinations is very limited. Some players have calculated that the probability of Tianhu is about 0.0003%, which means that Tianhu is only likely to occur once every 330,000 games played on average. Of course, this is only a theoretical value. In actual games, due to random factors such as shuffling and card coding, the appearance of Tianhu is even more difficult to predict.

Factors affecting the probability of Tianhu

  • number of cards: Playing mahjong usually uses 136 cards (36 each for ten thousand cards, strips and drums, plus 4 wind cards). Compared with the gameplay of 144 cards (including flower cards), the probability of Tianhu is slightly higher.
  • Hu brand type: Tianhu requires the starting card to be a Hu card type, while Hu card types are diverse, such as flat Hu, seven pairs, and touching Hu. Different card types have different requirements for starting hands, and the probabilities also vary. For example, the probability of seven pairs of Tianhu is much lower than that of Pinghu Tianhu.
  • Bookmaker rules: In rotating mahjong, only the dealer has the opportunity to have a chance to play the game, because the game is the game when the dealer starts. Therefore, the rotation of the dealers will also affect the frequency of Tianhu appearing.

Learn about the practical skills of Mahjong Tianhu

Although Tianhu mainly relies on luck, players can still use some techniques to increase Tianhu's chances or make the most correct decision when Tianhu appears.

1. Be familiar with Hu brand types and make quick judgments

The key to Tianhu is whether the starting hand has formed a Hu card type. Therefore, players must be familiar with all kinds of Hu card types, including basic Hu cards (4 pairs of straight or carving +1 pair of generals), seven pairs, touch Hu, uniform, etc. After touching the starting hand, quickly organize the card types and determine whether the card has been played. If you find out that it is Tianhu, you must decisively play the card and don't hesitate to avoid missing the opportunity.

2. Pay attention to the diversity of card combinations

Sometimes, the starting hand may satisfy multiple card types at the same time. For example, a hand can be either a pinghu or a seven pair. In this case, players need to choose the card method with the highest score according to the scoring rules for rotating mahjong. Generally, special card types (such as seven pairs, uniform) have higher rounds, so priority is given to the higher-round card type.

3. Keep calm and avoid exposure

Tianhu is extremely rare, and once it appears, it may attract the attention of other players. After confirming the Tianhu, players should remain calm and not be too excited, so as not to expose the card type or affect subsequent operations. At the same time, it is necessary to announce Tianhu quickly and accurately and display the card type to ensure that other players have no objections.

4. Understand the rules and avoid controversy

Different mahjong rules may have different regulations on Tianhu, such as whether Tianhu is allowed, Tianhu's number is counted, whether it needs to be reported, etc. Players should understand the rules clearly before playing to avoid disputes due to unclear rules. If the rules allow Tianhu, then when Tianhu appears, the rules must be strictly followed.

Turn around the scores and rewards of Mahjong Tianhu

As the top card type in mahjong, Tianhu usually enjoys a very high number. In rotating mahjong, the number of times of Tianhu varies according to regional rules, but it is generally above the Grand Slam, and some rules even directly set the highest number. For example, in some mahjong rules, Tianhu is counted as 88 times, ranking with eighteen arhats, big four xi and other card types. In addition, Tianhu often receives additional rewards, such as the "Tianhu Award" or "Lucky Prize". Therefore, once the game is over, the player will gain a huge point advantage and may even directly win the entire game.

Common scoring methods for Tianhu

  • fixed number: Tianhu is directly counted as a fixed number, such as 88, 64, etc.
  • factor calculation: Tianhu is multiplied by a certain multiple to the number of basic Hu cards, such as 4 times, 8 times, etc.
  • capped number: Tianhu directly reaches the maximum number, such as the "Tianhu capped" rule.

Go around the anecdotes and records of Mahjong Tianhu

Due to the rarity of Tianhu, whenever a player plays Tianhu, it will become a hot topic among poker players. On some Mahjong forums and social media, players often share their experiences of Tianhu and attach screenshots of the card type. These real cases not only prove the existence of Tianhu, but also inspire other players to continue to pursue this "miracle". In addition, some mahjong competitions will also record the appearance of Tianhu as a highlight of the event.
