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
- corroborated two or more independent sources agree on the facts that define this variant
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] | 136 | 13, out on 14 | none | determine the total faan of the winning hand, then square it to arrive at the portion | winner only |
- [1] Sloperama states WMPA is Korean and BASED ON JAPANESE MODERN, which matches the chart's placement under Modern rules. Book: WORLD MAHJONG Essence, by Kingstone Kim
Reading it
136 tiles, no flowers, and the distinctive squared-faan scoring. Sloperama states independently that WMPA is Korean and based on Japanese Modern, which is exactly the placement the chart gives it, under the Japanese branch but coloured Korean.

Descends from Modern rules, as the source chart draws it.
