| 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 | — | — | — | — |

- [4] 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
Reading it
The best-evidenced node in the mainland group: five sources, four of them independent of the chart. All agree on 108 tiles with honours and flowers removed, the one-missing-suit requirement and the continuation of play after the first win. The wiki independently dates the Chengdu adoption to the 1990s, matching the chart. Two sources also qualify the no-chow rule: chows cannot be called from a discard except to complete a winning hand, which is narrower than a flat prohibition.
