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 | — |
| [3] | — | 13, out on 14 | none mentioned | hands include 素 (no wild, doubles), 一条龙 (pure straight), 七对 (seven pairs), 豪华七对, 捉五魁 (winning on a lone Five of Characters), 清一色, 杠上开花, 海底捞月, 天和/地和 | — |
| [4] | 136: three suits and the seven honours, four each; no flowers | 13, out on 14 | — | fan doubling: a hand of n fan pays 2^n, no cap. 1 fan: self-draw, concealed, all pungs, all-claimed, 捉五魁, last tile; 2 fan: pure straight, seven pairs, winning on a kong replacement; 3: full flush; up to 9 for four wild tiles | dealer and discarder pay double; a discarder pays for all the losers ('点炮包装'); kongs earn the winner 1 (exposed) or 2 (concealed) base from each other player |
- [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
- [3] Read at the source (unreferenced). 'Beijing mahjong is a regional rule set that took shape gradually after the 1990s', also called 推倒和. The wild tile 混儿 replaces any tile; it was once taken from the seventh stack from the end, but to stop cheating it is now set by the first tile turned after the deal, with the tile one higher wild ('上滚混儿': a Five of Characters turned makes the Sixes wild). A wild tile may not be used in a chow or pung. Under 吃碰提, a player who has chowed, punged or made an exposed kong may win only by self-draw. 'In most of Beijing' a kong is not scored if its holder does not win
- [4] Read at the source. Two common forms: 推倒和, any valid hand wins, and 吃碰提, where a player who is not concealed may win only by self-draw. Kongs 'do not count as fan when winning, but score extra'
Reading it
The tile set and the wild tile are now settled; the scoring is not as Sloper has it. Tiles: 136, no flowers. Ourgame's rules list them, and the 2016 blog's wall arithmetic gives the same. Sloper's '144 (assumed)' was a guess. Wild tile: the 混儿. Chinese Wikipedia and the blog agree that a tile is turned up after the deal and the tile one higher becomes wild; Wikipedia adds that it was once taken from a fixed place in the wall and was moved to stop cheating. Hands: Sloper's three special hands are all real, as 七对, 一条龙 and 捉五魁 (winning on the Five of Characters), but there are more: all pungs, full flush, the luxury seven pairs, last-tile and replacement-tile wins. Scoring: Ourgame doubles by fan, 2 to the number of fan with no cap, with the dealer and discarder paying double and a discarder paying for everyone. Chinese Wikipedia says that in most of Beijing a kong scores nothing unless its holder wins, and Ourgame pays kongs only to the winner. That contradicts Sloper's 'even non-winners score for kongs'; it may be a house rule his informant knew. Chinese Wikipedia dates the style to after the 1990s, and gives it a second form, 吃碰提, in which an open hand may win only by self-draw.
