'''Daisharin''' {{kana|大車輪}} is one of three yakuman awarded for a closed hand with the following pattern: '''22334455667788'''.  The name daisharin applies to the pinzu.  Using the exact same number pattern, '''daichikurin''' {{kana|大竹林}} and '''daisuurin''' {{kana|大数隣}} apply to [[souzu]] and [[manzu]] respectively. Despite the difficulty of attaining this pattern, they are classed as [[Optional yaku|optional]].
'''Daisharin''' refers to a group of three [[optional yaku|optional]] yakuman: '''daisharin''' {{kana|大車輪}}, '''daichikurin''' {{kana|大竹林}} and '''daisuurin''' {{kana|大数隣}}. They are each scored by having a closed hand that contains: '''22334455667788''', all of the same suit. As optional yakuman, they may or may not be included in the game.


Despite the fact that they are technically three different yaku, they are often referred to collectively as daisharin: a ruleset which uses daisharin usually implicitly also uses the other two, and occasionally a daichikurin or daisuurin hand will be incorrectly referred to as daisharin.
The yakuman named "daisharin" itself refers to this pattern with [[pinzu]]; "daichikurin" applies to [[souzu]], and "daisuurin" applies to [[manzu]]. Calling a hand with souzu as "daisharin" would be incorrect. But, while they are technically three distinct yaku, most rulesets that include the pinzu daisharin also include daichikurin and daisuurin as well.

Daisharin refers to a group of three optional yakuman: daisharin 「大車輪」, daichikurin 「大竹林」 and daisuurin 「大数隣」. They are each scored by having a closed hand that contains: 22334455667788, all of the same suit. As optional yakuman, they may or may not be included in the game.

The yakuman named "daisharin" itself refers to this pattern with pinzu; "daichikurin" applies to souzu, and "daisuurin" applies to manzu. Calling a hand with souzu as "daisharin" would be incorrect. But, while they are technically three distinct yaku, most rulesets that include the pinzu daisharin also include daichikurin and daisuurin as well.

Pattern

The pattern for daisharin differs only in which tile is used to win the hand, and will always have at least one yasume tile:

Agari: Yasume:

The same applies to daichikurin:

Agari: Yasume:

and daisuurin:

Agari: Yasume:

Scoring

When classified as distinct yaku, daisharin and company are awarded yakuman. Even if they are not used, however, than hands are worth at least a 11-han sanbaiman:

The high score that this hand naturally achieves helps to explain why it is uncommonly scored as yakuman.
