Value
The MCR fan catalogue is based on the WMO 2006 reference. The calculator applies mahjchina’s implemented scoring and one-winner payments; it does not reproduce every tournament procedure. Rule choices & sources →
- A win needs at least 8 points excluding flowers. Once qualified, add 1 per flower. All 81 fans are listed; explicit exclusions in the table are not the entire compatibility rule set.
- Sets cannot be reused arbitrarily. High fans may exclude lower ones, and the wait and winning tile affect scoring. For Last Tile, enter visible tiles separately, excluding this hand and the winning tile.
- For final score F, self-draw charges each opponent 8+F. On discard, the discarder pays 8+F and the other two each pay 8. F includes flower points.
