At the mahjong table, the most exciting moment isPlaying Mahjong will make it difficult--Also known as "Tianhu". This kind of card type that can be encountered but cannot be sought not only requires extreme luck, but also involves complex probability calculations and rule judgments. This article will provide an in-depth analysis of the definition, probability of occurrence, differences in rules in various places, and how to rationally view this rare event to help you better seize the opportunity in actual mahjong combat.

What is "playing mahjong makes you crazy"?

"Playing mahjong will get ugly" usually means in mahjong terminologyheavenly hand, that is, after the dealer completes the card allocation, he directly cards the card without playing a card. Tianhu is one of the highest-level lucky cards in mahjong, and its rarity is comparable to winning a lottery ticket. The opposite is "local hu", which refers to the player playing cards in the first round of drawing cards. Whether it is a Tianhu or a Tianhu, the starting card type is required to directly meet the Hu card conditions without any adjustment.

The basic conditions of Tianhu

  • Must be the dealer (starting 14 cards)
  • Cards are played immediately after allocation, without operations such as playing cards, eating and touching bars
  • The card type conforms to the Hu card structure of the Mahjong rules (such as basic Hu, seven pairs, thirteen ones, etc.)

How low is the probability of Tianhu?

The probability of Tianhu is a topic that mahjong enthusiasts talk about. 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 few hundred thousand to one in a millionbetween. Taking China standard mahjong (136 cards, excluding flower cards) as an example, the number of combinations of the banker's starting 14 cards is about 3.26×10^18, and the combinations that can directly play cards account for only a very small proportion. Some researchers have used simulation calculations to find that the probability of Tianhu is approximately0.0003%, that is, it may only occur once in every 330,000 games. This means that even if you play 10 games of Mahjong every day, it may take nearly a hundred years to encounter Tianhu once.

Differences in Mahjong Rules in Different Places

Mahjong rules in different regions have different identification and number calculations for Tianhu. Understanding these differences can help avoid disputes in actual combat.

Sichuan Mahjong

Sichuan Mahjong (bloody battle to the end) usually does not have Tianhu rules, because its playing requirements are missing one game, and it is difficult for the starting hand to directly meet the Hu conditions. However, some local gameplay will recognize Tianhu and give extremely high numbers.

What should I do if I encounter Tianhu? Practical strategies and mentality adjustment

Although Tianhu relies entirely on luck, understanding relevant strategies and mentality management can make you more relaxed at the table.

Confirm rules and avoid disputes

Before starting, be sure to confirm with your poker players the identification criteria for Tianhu: Does it have to be a banker? Is it allowed to make up cards behind the hidden bar? Do you calculate self-touching? Different rules can lead to completely different results.

Keep calm and score reasonably

Once Tianhu appears, it is often accompanied by high numbers. As players, you should clearly report the type and number of cards played; as other players, you should respect the rules and avoid emotional disputes.

Reasonably treat the ingredients of luck

Mahjong is essentially a game of probability, while Tianhu is just an event of extreme luck. In the long run, technology is the key to determining the outcome. Don't be superstitious about "luck" just because of a sudden change, and don't lose your mentality because of someone else's sudden change.

Common misunderstandings about Tianhu

  • Myth 1: Tianhu must be wordless and flowless? This is not the case. As long as the card type conforms to the structure of the Hu card, the word card and flower card will not affect the identification of Tianhu.
  • Myth 2: Tianhu must be the biggest fan? In some rules, Tianhu may be combined with other varieties, but it is not the absolute largest. For example, the "Big Four Happiness + Tianhu" in the national standard mahjong can exceed 88 times.
  • Myth 3: Can Tianhu be manipulated by humans? Under formal shuffling and licensing conditions, Tianhu is completely random, and any technique that claims to increase the probability of Tianhu is nonsense.
