Honitsu (Half Flush)
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.

Chinitsu (Full Flush)
6 HanA hand made entirely of one numbered suit. 6 han closed, 5 han open — the highest non-yakuman han floor in the catalogue. Common when one suit floods your hand; stacks naturally with pinfu, iipeiko or ittsu inside the same suit.
Yakuhai (Value Tiles)
1 HanA 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.
Toitoi (All Triplets)
2 HanA 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.
Chanta (Outside Hand)
2 HanEvery 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.
Junchan (Pure Outside Hand)
3 HanLike 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.
