Riichi: Pinfu (All Simples)
Riichiranking
What is pinfu?
Pinfu is a one-han yaku in Japanese riichi mahjong. The hand must be all simples (no terminals or honors in the winning shape), formed from four sequences and one pair, with a two-sided wait on the pair. It is one of the most common beginner yaku.

When it applies
- Hand is fully closed (no open melds) for the standard pinfu definition in many rules.
- No triplets or quads in the four melds — only sequences.
- The winning tile completes a two-sided pair wait (ryanmen).
Pinfu often combines with riichi, tsumo, or ura dora for extra han. Use the generator below to tweak tile art or export a teaching image.
