Value
mahjchina Sichuan profile: no chow, clear the missing suit, root-adjusted base capped at 8. Self-draw normally pays base + 1 from each active opponent; previous kong transfers are separate. Rule choices & sources →
- Clear the missing suit; pung and kong are allowed, chow is not. Table values are bases, not MCR points or Riichi han. Each root (four identical tiles, including kongs) doubles the base, capped at 8. Dragon Pairs roots use the same calculation.
- With root-adjusted base B: discard B; self-draw B+1; rob kong, discard after kong or last discard 2B; last draw 2B+1; kong draw 4B+1. Exposed-kong draw is paid only by that kong’s discarder; other self-draws charge active opponents.
- By default only the base is capped. Event-cap mode limits discard to 8 and self-draw to 9. Heavenly/Earthly hands use base 8; last-tile and kong events can combine. Prior kong payments, draw-ready checks, missing-suit penalties and kong refunds are outside this single-win calculation.
