* '''Ryantan''' | * '''Ryantan''' ([[ryanmen]] + [[tanki]]): Appears as a triplet with a tile adjacent, where none of these tiles are [[terminal]]s. Example: 2223, which can be treated as 22 + 23 (ryanmen) or 222 + 3 (tanki). | ||
* '''Kantan''' | * '''Kantan''' ([[kanchan]] + tanki): Appears as a triplet with a tile numerically 2 apart. Example: 2224, which can be treated as 222 + 24 (kanchan) or 222 + 4 (tanki). | ||
* '''Pentan''' | * '''Pentan''' ([[penchan]] + tanki): Appears as a triplet with a tile adjacent, where either the triplet or adjacent tile are composed of terminals. Examples: 1112, which can be treated as 111 + 12 (penchan) or 111 + 2 (tanki). | ||
In order to enter [[tenpai]] with any of these waits, the hand must not have any other pairs. If it already has a "stable" pair, the adjacent tile can be treated as a floating tile. | In order to enter [[tenpai]] with any of these waits, the hand must not have any other pairs.
