Honroutou (All Terminals and Honors)

A hand made of four triplets (or kans) and a pair — no sequences. Often built from middle-game pon calls; pairs naturally with sanankou (three concealed triplets) and yakuhai for high-han open hands.

Every meld and the pair contains at least one terminal or honor tile. 2 han closed, 1 han open. Sequences are restricted to 1-2-3 and 7-8-9 — the only ones containing a terminal. Junchan is the honor-free 3 han version.

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.

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.

Yakuman. A hand composed entirely of honor tiles — winds and dragons only. Often built around a chiitoitsu shape because honors form pairs more easily than triplets. Stacks with honroutou and (sometimes) shousangen for double yakuman in stricter rulesets.
