  • [1] information from Laurent Mahe
  • [2] each player builds a wall 17 tiles wide and two high, which is 136 tiles across four walls, confirming the count arithmetically. The face-up tile is the wild indicator and the four tiles of the same suit one greater in number are wild; a nine makes the ones wild, a wind makes the next wind in East-South-West-North order wild, a dragon the next in Red-Green-White order. A wild tile substitutes for any tile in a winning hand

Reading it

A second source settles what the first could not, and contradicts it. Sloperama assumed 144 tiles and recorded flower handling as unknown; the blog it cites states 136 tiles and that the eight flower and season tiles are not used, and its 17-wide two-high wall confirms 136 arithmetically. Prefer 136 and no flowers. The wild-tile mechanism the chart summarises as 'drawn wild tile' is corroborated and much more specific than either summary: the indicator is face up, and the wild tiles are the four one greater in number, wrapping from nine to one.
