In Japanese mahjong, yaku (Japanese: 役) is a condition that determines the value of the player's hand. It is essential to know the yaku for game strategy, since a player must have a minimum of one yaku in their hand in order to legally win a hand. Each yaku has a specific han value. Yaku conditions may be combined to produce hands of greater value. The game also features dora, that allow a hand to add han value, but they do not count as yaku. Altogether, a hand's points value increases exponentially with every han.
Overview
Yaku are somewhat similar to poker hands. They fit certain patterns based on the numbers or types of tiles included, as well as the relative value of the tiles. Unlike poker, however, multiple yaku may be combined to produce hands of greater value.
Yaku are divided into three categories:
- Hands that are mandatory to be closed (menzen-nomi, 門前のみ).
- Hands that loses one han if the hand is open ("Eat and decrease", a literal translation of kuisagari, 喰い下がり)
- Hands that can be closed or open and retain the same han value.
All hands start closed. A hand becomes open as soon as the player "calls" a tile discarded by an opponent, in order to complete a group from their own hand. This is called "melding." For example, if a player has 
in their hand, and an opponent discards a , the first player may call the discard, and thus create a melded triplet. This process can also create melded sequences (e.g. 2-3-4 of the same suit), and open quads. The calling player must display the completed group by placing the tiles face-up on the table. This makes the hand "open".
No open hand can become closed.
The only time a player can call an opponent's discard and still have their hand remain closed is when they are calling the winning tile. For scoring purposes, the melded group is considered open, but the overall hand stays closed (menzenchin 門前清 or menzen 門前).
The basic concept of a yaku is that it fits into one of three basic criteria:
- It contains a pattern of some kind
- It can consistently be formed during a game, although it does not necessarily need to be common
- It is based on specific game situations, such as discards or actions taken by other players
Finally, when it comes to points scoring, the total number of han in the hand is counted. When the han value is 4 or less, fu is also counted. The combination of the han value and fu value corresponds to a points table.
List of yaku
The following is a list of all the yaku, their names in English and Japanese, their han values, and any special conditions related to them. They are listed here in groups according to the underlying patterns that define the yaku. Example hands are given, but often, many other arrangements are possible for each yaku. All yaku can be divided into seven basic categories, depending on the dominant feature. The features are as follows: patterns based on sequences, patterns based on triplets/quads, patterns based on terminals/honors, patterns based on suits, maximum-value hands (yakuman), lucky circumstances, and special criteria.
Special criteria
| Name | Japanese | Han value | Remarks |
|---|---|---|---|
| Riichi / Ready | rīchi – 立直, リーチ ("ready") | 1 | Closed hands only |
| The most common yaku in Japanese Mahjong, hence why the game is called Riichi Mahjong. Among all yaku, riichi occurs at least 40% of the time across different mahjong platforms and professional settings.[1] This yaku is often called "reach" because its Japanese name is phonetically similar to the English word.
When a player's hand needs only one tile to win (tenpai) and the hand is closed (i.e. the player has not called any opponent's discards to make melds), then the player can opt to declare riichi.
To make a declaration, the player calls out “riichi”, discards their tile by placing it sideways, and places a 1,000-point stick on the table, as a deposit. From then on, any tile they draw must be automatically discarded if it does not give them a winning hand. In this way, they cannot change the content of their hand in any way (except declaring certain closed quads). In some rulesets, a player can declare riichi only when there are four or more tiles remaining in the wall. That is, if they cannot draw another tile, they cannot declare riichi. The player is not penalized if drawing another tile is prevented due to opponents making open melds or closed quads after the riichi declaration.[2] If all four players have declared riichi, a hand ends as an abortive draw. Players show their hands to confirm they are tenpai, or they are penalized with chombo.[3]
When a player declares riichi and wins, they get access to ura dora indicator tiles. These are just like regular dora, but the indicator lies beneath the dora tile in the dead wall. The ura dora is only revealed after the hand is won, so it is impossible to strategize around achieving ura dora. If multiple dora are present (due to kan calls), then each one reveals an ura dora.
The winner of a hand receives all 1,000-point riichi sticks that are present. In the case of multiple winners, the player closest to the discarding player (moving forward) receives all riichi deposits. If a hand ends in a draw, any riichi deposits carry over to the next game and are placed near the counters. The next winner receives those riichi deposits. In most cases, if a draw results in ending the game (such as exhaustive draws in the final round with the last dealer not ready to win, or exhaustive draws causing one or more players to reach a negative score), all riichi deposits are forfeited and the game is simply over.
When a player declares riichi and discards a tile (sideways), an opponent may call that tile for a meld. The riichi player, on their next turn, places their next discard sideways. Additionally, if a riichi discard tile is called by another player to win, then the would-be riichi declaration is considered incomplete and therefore no riichi deposit is forfeited.[2]
A player who has declared riichi can still make one kind of call: a closed quad (kan). This can only happen when they have a triplet in their hand and they draw the fourth tile. Even though the hand remains closed, the quad is still displayed on the table. While in riichi, a quad call must not otherwise change the composition of the hand or its waits.[2][3] For example, when a player has | |||
| Seven Pairs | chītoitsu – 七対子, or chītoi – 七対 | 2 | Closed hands only |
      | |||
| A hand completely composed of pairs — no sequences, triplets, or quads. The hand is one of the two exceptions to the rule requiring winning hands to have four groups and a pair, the other being Thirteen Orphans. This hand also has its own special rules for scoring, where it has fixed fu value of 25. This yaku cannot be combined with īpeikō (Twin Sequences) or ryanpeikō (Double Twin Sequences).
In general Japanese rules, all seven pairs must be unique, meaning that the same four tiles may not be split into two pairs. Some rules, such as in the Kansai region, may accept four of the same tile, but they are not considered a quad.[4] | |||
| Nagashi mangan | nagashi mangan – 流し満貫 | mangan | Open or closed |
| This yaku is based on discarded tiles, instead of the hand itself. A player's discards must be all terminals (1s and 9s) and honors (dragons/winds), and the hand must end in a draw (not including abortive draws). In most rules, the yaku only applies if no opponent called a discard from the player's discard pile. Certain rules allow the player to make open melds.[5] In most cases, the value of this yaku is mangan. When determining points, the hand is regarded as winning by self-draw (tsumo). The rule of nō-ten bappu is usually not applied to this case, as it is no longer regarded as a draw. In addition, this hand cannot be combined with other yaku. | |||
Yaku based on luck
These hands are all worth one han.
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| Tsumo / Self-pick | menzenchin tsumohō – 門前清自摸和, or shortly tsumo – 自摸, ツモ | 1 | Closed hand only |
| When a player has a closed hand and draws a winning tile from the wall or the dead wall, one han is added, even when the hand previously had no yaku. Open hands cannot receive this yaku. | |||
| Ippatsu / One-shot | ippatsu – 一発 | 1 | Requires riichi (or double riichi) |
| After declaring riichi (or double riichi), one han is added if the player wins within one go-around of play. They may win by calling an opponent's discard, or by a self-drawn tile (tsumo). If the latter, they still receive the extra han from tsumo. If the go-around is interrupted by another player calling a meld, then ippatsu no longer applies. For example: Player 1 declares riichi, Player 2 discards a tile, Player 4 calls that discard for a meld (thus skipping Player 3 and interrupting the go-round), Player 4 discards following their meld, and Player 1 draws their winning tile for a tsumo. In this case, ippatsu does not apply. | |||
| Last Tile Draw / Under the Sea | haitei raoyue – 海底撈月, or haitei – 海底 | 1 | Open or Closed |
| A player wins when they draw the very last tile (not including the dead wall). The term haitei raoyue translates as "scooping up the reflection of the moon from the bottom of the sea." This is a Chinese idiom (sometimes used in Japanese as well) to mean a futile task.[6] | |||
| Last Tile Claim / Under the River | hōtei raoyui – 河底撈魚, or houtei – 河底 | 1 | Open or Closed |
| A player wins when they call the very last tile, discarded by an opponent. Houtei raoyui is a pun on haitei raoyue (see previous yaku explanation). It means "catching fish from the bottom of the river." The word for "river" (河, or kawa) is also the term for the discard pile in mahjong (also known as the "pond"). Hence houtei is a pun referring to both haitei, and the act of catching a fish from the bottom of the discard river. | |||
| Dead Wall Draw / After a Quad / After a Kan | rinshan kaihō – 嶺上開花, or rinshan – 嶺上 | 1 | Open or Closed |
| A player wins by drawing a supplemental tile from the dead wall, which is done after declaring a quad (kan). Rinshan kaihō means "a flower blooms on a ridge".
Sometimes the pao (包) rule is applied to this yaku. That is, if a player claims a discard to make an open quad and then completes their hand with a tile drawn from the dead wall, the player who discarded the tile is responsible for paying the entire amount for the hand. | |||
| Robbing a Quad / Robbing a kan | chankan – 搶槓, 槍槓 | 1 | Open or Closed |
| A player wins when they call a tile that an opponent just used to declare a quad (kan). A player cannot rob a quad if they themselves previously discarded a tile used in that quad (due to furiten). The "robbed" player pays the full value for the hand.
Robbing a closed quad In most rulesets, a player cannot rob a closed quad, only an open one (i.e. after their opponent has "upgraded" an open triplet to a quad). Some rulesets have an exception: robbing a closed quad is allowed if it's used to complete Thirteen Orphans. However, the chankan yaku does not apply, since Thirteen Orphans is a yakuman hand and automatically scores the maximum number of points. | |||
| Double Riichi / Double-ready | daburu rīchi – ダブルリーチ, or daburii – ダブリー | 2 | Closed hand only |
| A player declares riichi on their first turn. All other riichi conditions apply. | |||
Yaku based on sequences
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| Pinfu / No-points hand | pinfu – 平和 | 1 | Closed hand only |
            | |||
| A hand that earns no fu points (which are calculated separately from han). Since each triplet/quad earns fu, the hand must be entirely sequences. Also, the hand's pair must not be made of dragon tiles/round winds/seat winds, since each of those earns fu.
Furthermore, the hand must be waiting for multiple winning tiles,[7] such as having Combination of pinfu and tsumo (self-draw of the winning tile) Normally, drawing the winning tile from the wall (known as tsumo) earns the winner 2 fu. But when the winning hand is pinfu, those 2 fu from tsumo are normally waived. Such a hand earns 2 han: 1 for pinfu, and 1 for tsumo (other han may apply too). Some (uncommon) rulesets say that tsumo invalidates pinfu. In this case, 2 fu are awarded, and only 1 han. The rule is called "pinfu–tsumo nashi" (平和自摸無し or 平和ツモなし, pinfu–tsumo invalid), sometimes contracted to "pinzumo nashi" (ピンヅモなし). The opposite rule is called "pinfu–tsumo ari" (平和自摸有り or 平和ツモあり, pinfu–tsumo valid).[8] | |||
| Twin Sequences | īpeikō – 一盃口 | 1 | Closed hands only |
    | |||
| Two sequences consisting of the same numbers, in the same suit. For example, the above hand has two copies of . | |||
| (Three) Mixed Sequences | sanshoku doujun – 三色同順, or sanshoku – 三色 | 2 (1 if open) | Open or Closed |
   | |||
| The same sequence, but in each of the three suits. For example, the above hand has 2-3-4 in all three suits.
Technically, the nickname sanshoku could also refer to sanshoku doukō (Three Mixed Sequences), but it almost always means this yaku, since the other is so rare. This yaku might also be called sanshiki, to avoid confusion (though this is rare as well).[9] | |||
| Full Straight | ikkitsuukan – 一気通貫, or ittsuu – 一通 | 2 (1 if open) | Open or Closed |
   | |||
| Three sequences of 1-2-3, 4-5-6, and 7-8-9 in a single suit (creating a full run from 1 to 9). Similar in concept to a "straight" in poker. | |||
| Double Twin Sequences | ryanpeikō – 二盃口 | 3 | Closed hand only |
   | |||
| Two independent sets of identical sequences (īpeikō). For example, the above hand has two copies of and two copies of .
Some rules may not allow the two sets to be the same, i.e. four identical sequences. This yaku does not apply to Seven Pairs, as the tiles are based on sequences, and not pairs. | |||
Yaku based on triplets and/or quads
When the following hands involve triplets, quads are also acceptable. But if they require quads, triplets do not count. Each yaku is worth 2 han, regardless of whether the hand is closed or open.
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| All Triplets | toitoihō – 対々和, or toitoi – 対々 | 2 | Open or Closed |
 | |||
| The hand consists of all triplets (or quads) and no sequences. If the hand is closed and won via self-draw (tsumo), then it becomes Four Concealed Triplets and is awarded yakuman instead. | |||
| Three Concealed Triplets | san'ankō – 三暗刻 | 2 | Open or Closed |
| | |||
| Three sets of triplets (or quads) formed without any called tiles. The tiles for the three triplets/quads must all be self-drawn, but the fourth group can be melded (i.e. formed by calling an opponent's discard). As long as the three triplets/quads remain hidden from opponents, then they are considered concealed, and the yaku still applies. The exception is a closed quad (kan), which is still considered concealed, despite being visible to the opponents. | |||
| (Three) Mixed Triplets | sanshoku doukō – 三色同刻 | 2 | Open or Closed |
 | |||
| The same triplet, but in each of the three suits. For example, the above hand shows 3-3-3 in all three suits. | |||
| Three Quads / Three Kan | sankantsu – 三槓子 | 2 | Open or Closed |
| called: + | |||
| Three quads (kan) in one hand. Each of the quads must be called, but can be open or closed. | |||
Yaku based on terminal or honor tiles
These hands involve terminals and/or honors, or lack thereof (such as tan'yao and yakuhai, due to their simplicity).
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| All Simples | tan'yaochū – 断么九, or tan'yao – 断么 | 1 | Open or Closed |
| | |||
| A hand with no honor tiles (dragons/winds) nor terminal tiles (1s and 9s). The hand may only contain numbered tiles from 2 through 8. If the hand is open, it is called "kuitan" (喰い断), which means tan'yao made by "eating" discards. In some rulesets, this hand can be closed only. The rule that does not allow kuitan is called "kuitan nashi" (喰い断無し; no kuitan, or kuitan invalid). | |||
| Honor Tiles | yakuhai – 役牌, or huanpai/fanpai – 飜牌 | 1 per each triples | Open or Closed |
| | |||
| Any triplet (or quad) consisting of dragons, the seat wind, or the round wind. If the winner has a triplet/quad that is both the seat wind and the round wind (such the East player in an East round with ), then it is worth 2 han. | |||
| Common Ends | honchantai yaochū – 混全帯么九, or chanta – チャンタ | 2 (1 if open) | Open or Closed |
| | |||
| Each of the four groups —and the pair— must include at least one 1, 9, or honor tile. Thus each group must be 1-2-3 or 7-8-9 of any suit, or a triplet/quad of 1s, 9s, or honor tiles (dragons/winds). If the hand has no honor tiles, then the hand is junchan and this yaku does not apply. If the hand has no sequences, then the hand is honrō and this yaku does not apply. | |||
| Perfect Ends | junchantai yaochū – 純全帯么九, or junchan – 純チャン | 3 (2 if open) | Open or Closed |
| | |||
| Each of the four groups —and the pair— must include at least one 1 or 9 (no honors). Thus each group must be a 1-2-3 or 7-8-9 of any suit, as well as a triplet/quad of 1s or 9s. If an honor tile is included (even in the pair), then the hand is chanta and this yaku does not apply. If the hand has no sequences, then it is honrō, and this yaku does not apply. | |||
| Common Terminals/All Terminals and Honors | honrōtō – 混老頭, or honrō – 混老 | 2 | Open or Closed |
| (All triplets)
| |||
| (Seven pairs)
| |||
| The hand consists entirely of terminals (1s & 9s) and honors (dragons & winds).
A honrou hand automatically earns a second yaku, either All Triplets or Seven Pairs (examples shown above). Both of those are worth 2 han, so in addition to this hand's 2 han, a honrou hand scores a minimum of 4 han. | |||
| Little Three Dragons | shōsangen – 小三元 | 2 | Open or Closed |
| | |||
| Two triplets (or quads) of dragons, plus a pair of the third dragon. If the hand instead has three dragon triplets/quads, then the yaku is Big Three Dragons (and scores yakuman).
Since an honor triplet always earns 1 han, this hand automatically earns an extra 2 han, bringing the total to 4 han (at minimum, since other yaku might apply). | |||
Yaku based on suits
The following two yaku are related to a single suit. They both lose one han when they are open.
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| Half Flush / Common Flush | hon'īsō – 混一色, or hon'itsu – 混一 | 3 (2 if open) | Open or Closed |
| | |||
| A hand containing tiles from only one suit, plus honors of any kind. If the hand has no honors, it is Full Flush. This yaku can apply to Seven Pairs. | |||
| Full Flush / Perfect Flush | chin'īsō – 清一色, or chin'itsu – 清一 | 6 (5 if open) | Open or Closed |
| | |||
| A hand containing tiles from only one suit. This yaku can apply to Seven Pairs. | |||
Yakuman hands
There is a special set of hands so difficult to attain that they are automatically worth the maximum amount of points. This value, along with the hands themselves, are called yakuman (役満, or yaku-mangan 役満貫).[10] All yakuman hands override all other han values. Some hands can form multiple yakuman (such as Big Four Winds + All Honors), but many rulesets do not award more points for this. On the other hand, some rulesets will give double the yakuman value, called daburu yakuman (ダブル役満).
Additionally, regular yaku can be combined to achieve the yakuman score, a situation known as kazoe-yakuman (数え役満) ("counted yakuman"). Any hand with 13 han (or more) automatically gets the yakuman score, even if it isn't one of the following yakuman hands.
The hands known as Thirteen Orphans, Four Concealed Triplets, and Big Three Dragons are considered relatively easy to complete among yakuman hands, and are collectively called "the three big families of yakuman" (Japanese: 役満御三家).[10]
Some of yakuman hands may have different names in some regions. The names used here come from the World Riichi Championship ruleset, which is also used by the American Riichi Mahjong League.[11]
| Name | Japanese | Value | Closed/Open |
|---|---|---|---|
| Thirteen Orphans | kokushi musō / kokushi musō jūsanmen machi – 国士無双 / 国士無双13面待ち (13 wait) | Limit / Double limit (13 wait) | Closed hand only |
| (Single-tile wait)
| |||
| (13-way wait)
| |||
Along with Seven Pairs (chītoitsu), this is the only other hand that contradicts the requirement for a hand to have four melds and a pair. The hand is simply: one of each terminal tile & honor tile, with an extra terminal/honor forming a pair. In other words, the hand includes one of each wind , one of each dragon , one of each 1-tile , one of each 9-tile  , and a duplicate.
If a player already has the pair but is missing a terminal/honor, then this is a single-tile wait, which will score yakuman if won. But if a player has acquired all 13 terminal/honor tiles, and they are simply waiting to create the pair, this is a 13-tile wait. Many rulesets will consider this double yakuman. The Japanese name of this yaku, kokushi musō, means "a peerless distinguished person in a country."[12] Other names for this yaku are shīsan yaochū (十三么九) which means "thirteen of smallest numbers and 9's [and honors]," or its abbreviation shīsan yao (十三么). | |||
| Four Concealed Triplets | sūankō – 四暗刻 / sūankō tankimachi - 四暗刻単騎待ち (single wait) | Limit / Double limit (single wait) | Closed / Open or Closed |
| (Double wait)
| |||
| (Single wait)
| |||
| A hand with four closed triplets/quads. The player may be waiting for one tile or two, depending on how many triplets/quads they have in their hand already. In the case of a "double wait", the player must complete the hand via tsumo in order to get yakuman. Otherwise, if they call another player's discard to complete a triplet, then the hand only achieves All Triplets and Three Concealed Triplets.
Meanwhile, if the player has a "single wait", then they are allowed to call the winning tile from an opponent's discard. In many rulesets, the "single wait" version is awarded double yakuman. | |||
| Big Three Dragons / Big Dragons | daisangen – 大三元 | Limit | Open or Closed |
| | |||
| A triplet (or quad) of each type of dragon tile. If the player only achieves two dragon triplets, and a dragon pair, then this is called Little Three Dragons, and is only worth 2 han. | |||
| Little Four Winds / Little Winds | shōsūshī – 小四喜 | Limit | Open or Closed |
| | |||
| A hand consisting of three triplets/quads of winds, and a pair of the fourth wind. | |||
| Big Four Winds / Big Winds | daisūshī – 大四喜 | Double limit (when allowed) | Open or Closed |
| | |||
| A hand consisting of four triplets/quads of winds. Some rulesets value this at double yakuman. | |||
| All Honors | tsūīsō – 字一色 | Limit | Open or Closed |
| | |||
| A hand composed exclusively of wind and dragon tiles. | |||
| All Terminals | chinrōtō – 清老頭 | Limit | Open or Closed |
| | |||
| A hand containing only terminals (1s & 9s). | |||
| All Green | ryūīsō – 緑一色 | Limit | Open or Closed |
| | |||
| A hand containing only pure-green tiles. This is exclusively the bamboo tiles of 2, 3, 4, 6 and 8, as well as the green dragon tiles. Many of the Japanese tile-sets color these specific tiles with just green, while all other tiles use another color (including the bamboo tiles of 1, 5, 7, and 9, which have red on them). But even if a tile set uses different color schemes, this yaku only applies to the tiles listed above.
The green dragon tiles are not necessary to complete the hand. | |||
| Nine Gates | chūren pōtō – 九蓮宝燈 / junsei chūren pōtō - 純正九蓮宝燈 (nine wait) | Limit / Double limit (9-wait) | Closed hand only |
| (Normal wait)
| |||
| (9-way wait)
| |||
| A hand composed of 1-1-1-2-3-4-5-6-7-8-9-9-9 of one suit, plus any other tile of the same suit. In other words, this is a Pure Straight, but the 1 and 9 are triplets (plus another tile in the suit).
In most rules, if the hand is waiting for any of the nine tiles (i.e. the hand is 1-1-1-2-3-4-5-6-7-8-9-9-9), then the player is awarded double yakuman upon winning. Regardless of the value of the extra tile, this is always a standard mahjong hand of four melds and a pair, as shown in the animation below:
| |||
| Four Quads / Four Kan | sūkantsu – 四槓子 | Limit | Open or Closed |
| called: + + | |||
| A hand consisting of four quads, either open or closed. Normally, a hand is declared a draw when four quads are called by multiple players. But if a single player calls four quads, then the play continues until a player wins, or a fifth quad is called by another player.
This yaku is considered the rarest & most difficult in all of Japanese mahjong, since the player must acquire 18 tiles to win (compared to the typical 14). Also, a player has to call each quad, making it obvious to the opponents that they are attempting Four Quads. The opponents can thus act defensively, and avoid discarding any tiles that haven't been seen yet. | |||
Yakuman on opening hands
The following are yakuman hands completed on the first go-around.
| Name | Japanese | Value | Closed/Open |
|---|---|---|---|
| Blessing of Heaven | tenhō – 天和 | Limit | Closed hand only, dealer only |
| A hand won by the dealer on the very first draw, regardless of its contents. Because the hand is closed and the winning tile is considered as a drawn tile, it fulfills the yaku criteria. | |||
| Blessing of Earth | chīhō – 地和 | Limit | Closed hand only, non-dealer only |
| A hand won by any non-dealer on the first tile they draw, regardless of its contents, and without declaring any open-meld, including closed quads.[13] Like Blessing of Heaven, this hand fulfills the yaku criteria of a closed-hand self-drawn tile. | |||
| Blessing of Man | renhō – 人和 | Depends on ruleset | Closed only, non-dealer only |
| When a player has yet to have a turn, but they call an opponent's discard to win. It must also be the first called tile of the hand.
Depending on the ruleset, this hand can be valued at yakuman, baiman, or mangan. In stricter rulesets, this is not considered a yaku at all, and requires other yaku to win. On other hand, some other rules are laxer, and say that a player can achieve Blessing of Man after their first turn, if the tile they are calling was their opponent's first discard. Because of these variations, this yaku is considered optional.[14] | |||
Ancient or local yaku
The following table details yaku and yakuman hands that are usually not recognized as valid but may appear in house rules.
| Name | Japanese | Value | Closed/Open |
|---|---|---|---|
| Three Chained Triplets | sanrenkō – 三連刻 | 2 | Open or Closed |
| | |||
| A hand with three number triplets (or quads) in one suit with successive numbers. This hand is a local rule and not an officially recognized rule for Japanese mahjong.[15] | |||
| Four Chained Triplets | sūrenkō – 四連刻 | Limit | Open or Closed |
| | |||
| A hand with four number triplets (or quads) in one suit with successive numbers. This hand is a local rule and not an officially recognized rule for Japanese mahjong.[16] | |||
| Chariot | Suit specific names (see below) | Limit | Closed only |
| | |||
| A hand composed of 2-2-3-3-4-4-5-5-6-6-7-7-8-8 of one suit. In other words, this is Seven Pairs and Full Flush, and all the numbers are successive. This hand is a local rule and not an officially recognized rule for Japanese mahjong.[17]
Each of the numbered suits may also use special names for this hand:
| |||
| Big Seven Stars | daichisei – 大七星 | Double limit | Closed hand only |
| | |||
| Seven pairs, all of which are honor tiles (dragons or winds). This combines the yaku of Seven Pairs and All Honors, which is why some score this as double yakuman. But it is very unusual to play with rules that allow this. | |||
| Thirteen Unconnected Tiles | shīsanpūtā / shīsanbudō - 十三不塔 | Limit | Closed only |
| | |||
| The hand contains thirteen tiles such that there are no groups, no pairs, and no number tiles closer than three apart from one another, plus an additional one of any of the tiles in the hand. Can only be claimed by a player on their first draw. | |||
| Fourteen Unconnected Tiles | shīsūpūtā - 十四不塔 | Limit | Closed only |
| | |||
| The hand contains fourteen tiles so that there are no groups, no pairs, and no number tiles closer than three apart from one another. Can only be claimed by a player on their first draw. | |||
| Eight Consecutive Wins | pārenchan – 八連荘 | Limit | Dealer only |
| A player wins eight times consecutively. The conditions of the hand depend on rules, which can be triggered by achieving either the ninth consecutive win onwards, or per every eight wins. It has nothing to do with the number of counters because the number increases when a hand is a draw. In some rules, no other yaku is necessary in the eighth winning. Some say the player must be a dealer from the first time. The player is always a dealer when the hand is accomplished. The hand is often optional.[18] | |||
