There are many different types of tiles. These categories are relevant to certain yaku and for fu scoring.

Simple

Tiles numbered from 2-8 are classed as chunchanhai 「中張牌」, or "simples". These include:

  • Used for tanyao ("All Simples"), which requires every tile to be a simple tile.

Tiles numbered 1 or 9 are classed as routouhai 「老頭牌」, or "terminals" in English. They are called "terminals" because they are always the end of a sequence; a tile group such as 9-1-2 is not a valid sequence. These include:

  • Wind tiles of the seat wind (e.g. West tiles as the West seat) are yakuhai.

They are:

Terminals:

Winds:

Dragons:
