How Chinroutou (清老頭) works

All terminals — every tile in the hand is a 1 or a 9, built entirely from terminal triplets and a terminal pair.

Chinroutou allows only the 1 and 9 of each suit, with no honors and no middle tiles, so the hand is necessarily all triplets (or kans) plus a pair. It can be open or closed since the structure forces triplets regardless. It is effectively a stricter, terminals-only subset of toitoi and honroutou and ranks among the top-tier hands.

Good to know
  • Only terminal numbers (1 and 9) are permitted; honors are not allowed, unlike honroutou.
  • The hand is inherently all triplets and a pair, so it overlaps with toitoi by construction.
  • Open and closed hands both qualify for this pattern.

Chinroutou (清老頭) — FAQ

Can chinroutou include honor tiles?

No. Adding any wind or dragon makes it honroutou instead; chinroutou is purely 1s and 9s.

Why is chinroutou always made of triplets?

With only terminals available, no sequences can form, so every set must be a triplet or kan plus a pair.
