Analysis
Written by an AI model from the sources above. It is a reading of them, not a source in its own right: every figure in it points back to a numbered source, and where the two disagree, the source is right.
Assessment
- Confidence
- catalogued listed in a variant catalogue with tile counts and hand sizes, but no rules text verified
- Evidence
- conflicting sources disagree materially, or one source contradicts itself
Cross-comparison
What each source was read to say, set side by side. The numbers are the sources above.
| Source | Tiles | Hand | Flowers | Scoring | Payout |
|---|---|---|---|---|---|
| [1] | 144 (assumed) | 13, out on 14 | unknown; the first picked tile dictates the wild tile, by similar logic to Japanese dora | no minimum; 1 point per pung, 2 per kong (non-winners score for kongs too); kong doubles winner's score; only three special hands | winners and kong holders |
| [2] | 136, three suits plus four winds and three dragons | — | the eight flower tiles, four seasons and four flowers, are NOT used | no open set or kong may contain a wild tile | — |
- [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.
