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
- documented a published ruleset or rule description exists and is cited
- Evidence
- partial sources agree on some points but disagree or say nothing on others
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 | points-based; doubles built into the system | winner only |
| [2] | 136 in 34 designs, four identical tiles of each | 13 | none in the scoring system; bonus tiles noted as an optional addition some players make | 44 patterns in categories and series, additive, with no basic points at all | only the winning hand is scored; the winner collects from the other three by a payoff scheme |
- [2] the designer's own official site, carrying version 3.3 of the system and his book Zung Jung: a Perspective of Mahjong History. It gives no creation date for the system
- [3] describes the general landscape of attempts at an international scoring standard, of which Zung Jung is one, and notes that most are not widely accepted
Reading it
The rules are now primary-sourced: Alan Kwan's own site gives 136 tiles, a 13-tile hand, 44 additive patterns with no basic points, and winner-only payment, all matching Sloperama. That is the strongest evidence any node in this compendium has, because it comes from the system's designer. The date and the parentage remain open: the official site gives no creation date, so the chart's 2000s against the wiki's 1990s is still unresolved, as is whether Zung Jung descends from Guangdong Style or sits beside it.
