Chanta (Outside Hand)

Like chanta but contains no honors — every meld and the pair contains a terminal (1 or 9). 3 han closed, 2 han open. Higher value than chanta but brittle: a single honor tile anywhere in the shape downgrades the hand to chanta.

Every tile is a terminal (1 or 9) or honor. 2 han. Since terminals and honors cannot form sequences, the hand always pairs with toitoi or chiitoitsu — the resulting stack is typically 4 han or more before dora.

A triplet (or kan) of any dragon, the round wind, or the player's seat wind. Each qualifying triplet scores 1 han, and a triplet that doubles as both round-and-seat wind (renpuuhai) scores 2 under most rulesets. The simplest open-friendly yaku in the game.

The same numerical sequence in all three numbered suits (e.g., 234m / 234p / 234s). 2 han closed, 1 han open. Often paired with pinfu or tanyao, and structurally exclusive with ittsu — pick one or the other based on whether your early draws cluster vertically or spread horizontally.

A hand containing only one numbered suit plus honor tiles. 3 han closed, 2 han open. The workhorse high-value open yaku — combined with a yakuhai triplet it routinely clears mangan even after multiple calls.
