AI summary A magazine feature on regional mahjong in China, with a section on Sichuan and Chongqing that separates 血战到底 from 血流成河. Its Guangdong section repeats the 2007 game-site text on the four schools (鸡平胡, 推倒胡, 新章, 老章) almost word for word, so it is not an independent witness for Guangdong.
for this variant Separates the two 'bloody' forms the other sources run together: the battle to the end and the river of blood.

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] | 108 across 3 suits, ranks 1-9, four copies each; no winds, dragons or flowers | — | — | — | — |
| [2] | 108: any set with all honour tiles, flower tiles, red fives and jokers removed, leaving four each of 1-9 in three suits | — | — | — | — |
| [3] | 108 in three suits, Wan, Bing and Tiao | — | — | tournament form caps the multiplier at three fan and adds game scores, explicitly to reduce luck | — |
| [4] | 108 | — | — | fan doubling (2^fan), usually capped at 3 or 4 fan; online platforms higher (up to 8 on Tencent's Happy Mahjong) | — |
| [5] | 108: bamboo, dots and characters; no flowers, winds or dragons | — | — | — | — |
- [6] Morten Andersen, newsgroup November 2007, on Sichuan style as played in Chengdu: kongs score very well; play continues after the first player goes out and does not stop until three players are mahjong or the wall runs out; penalty for holding all three suits at the end
- [1] MIL 'Brief Introduction to Bloody Mahjong' fetched as PDF; blood-battle continuation and missing-suit requirement
- [2] translates the name as Bloody Battle to the End. A chow cannot be called except for a winning hand, which is narrower than a flat no-chow rule
- [3] describes Blood Battle as one of the most widely recognised and adopted mahjong rulesets within China, and states the one-missing-suit requirement
- [4] Read at the source (unreferenced). Calls 血战到底 a feature of the Chengdu rules, 'the representative rules of Sichuan mahjong', and lists four Chengdu forms: standard, with kongs ('rain'), with blood battle, and with both
- [5] Read at the source. 'Popular in the Sichuan and Chongqing regions … particularly prevalent in Chengdu'; core mechanics are lacking a suit and the flower-pig check after a draw; after one player wins 'the remaining players continue playing until three players have won', so 'the player who wins first does not necessarily gain the most profit'
- [7] Read at the source. In Chengdu 'you must lack one suit, and there are only 筒条万'; the common forms are 血战到底, where each player may win once and play ends when three have won or the wall is gone, and 血流成河, where a player may win many times and play ends only with the wall. Describes a Chongqing underwater game of 'blood battle' Chengdu mahjong
- [8] Read in abstract only. A study of mahjong 'at the turn of the twenty-first century' in Chengdu, at four levels: neighbours, the Residential Committee, the municipal government and official media, and the state
Reading it
The best-evidenced node in the mainland group, and now in two languages. English sources (the MIL, MahjongPros, the World Mahjong Tour) and Chinese ones (Chinese Wikipedia, Baidu, Chinese National Geography) agree on 108 suit tiles, a hand short of one suit, play continuing after the first win until three have won or the wall is gone, and a penalty at a draw for a hand still in three suits. Two refinements. Chinese National Geography separates 血战到底 (each player wins once) from 血流成河 (a player may win again and again, play ending only with the wall); the English sources call both 'bloody'. And chows cannot be called from a discard except to complete a win, which is narrower than a flat prohibition. The date is weaker than the rules. Only the wiki puts the Chengdu adoption in the 1990s. Wang Di's study of Chengdu mahjong at the turn of the century is the scholarship that would test it, but only its abstract was readable, and that does not mention the rules.
Looked for, not found
- Law No law bears on the rules; Wang Di (2014) covers the city government's dealings with mahjong, read in abstract only.
- Historical No source dating the first 血战到底 games was found; Chinese searches turn up rules and strategy, not origins.
- Forum Zhihu threads on 血战到底 technique exist but refuse automated reads.
- Collection No museum or library record bears on the bloody rules.
