Yaku Based On Luck
These hands are all worth one han.
| Name | Japanese | Han value | Closed/Open |
|---|---|---|---|
| Self-pick | menzenchin tsumohou – 門前清自摸和, or shortly tsumo – 自摸, ツモ | 1 | Closed only |
| When a player has a closed hand and draws a winning tile from the wall or the dead wall, one han is added including when the hand previously had no yaku. Open hands are not applicable. | |||
| One-shot | ippatsu – 一発 | 1 | Closed only, riichi only |
| If a player declares ready and then completes their hand within one go-around of play, it adds one han to the hand’s value. The winning tile can be either a discard or a self-drawn tile. One-shot no longer applies when another player makes an open meld. | |||
| Last tile from the wall | haitei raoyue – 海底撈月, or haitei – 海底 | 1 | Closed/Open |
| If the last self-drawn tile that the last player draws before reaching the dead wall completes that player's hand, the hand’s value increases by one han. Haitei raoyue means "to scoop up the reflected moon from the seabed." | |||
| Last discard | houtei raoyui – 河底撈魚, or houtei – 河底 | 1 | Closed/Open |
| One han is added if a player wins on the last discard, that is, the tile discarded by the last player that drew the last tile from the wall. This hand is sometimes also referred to as haitei. Houtei raoyui means "to scoop up a swimming fish from the riverbed." | |||
| Dead wall draw | rinshan kaihou – 嶺上開花, or rinshan – 嶺上 | 1 | Closed/Open |
| When a player declares a quad, they must draw a supplemental tile from the dead wall to keep the number of tiles in the hand consistent. If that tile completes the hand, it adds one han to the hand’s value. Rinshan kaihou 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 | chankan – 搶槓, 槍槓 | 1 | Closed/Open |
| If a player has an open triplet and draws the fourth tile, they can add it to the triplet to make a quad. At the time, another player can win on the tile, namely, they can "rob" that tile. Doing so increases the hand’s value by one han.
Example: Player A has three 6’s of dots in an open triplet and draws the fourth 6, and added it to the triplet for a quad. If player B waits to win by having a 4-5 of dots left, they can win on that 6. Player A then has to pay the full value of the hand. Robbing a closed quad for thirteen orphans Sometimes, a "closed" quad can be robbed to complete the yakuman hand of thirteen orphans. For example, if player A makes a closed quad out of four west tiles, and player B is only waiting for a west to complete their thirteen orphans, player B can win on the west tile. The yaku is not counted in the case since the hand has a yakuman value. |
|||
| Double-ready | daburu riichi – ダブルリーチ, or daburii – ダブリー | 2 | Closed only |
| If a player can declare ready within the first go-around of a hand, they can call "daburu riichi" to declare a double ready for two han instead of one. All other conditions are the same as declaring a normal ready. | |||

Famous quotes containing the words based and/or luck:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
“The powerless worship Luck and Fate.”
—Mason Cooley (b. 1927)
