How 4 han 20 fu is calculated
Riichi payouts start from base points: fu × 2^(2 + han). For 4 han 20 fu that is 20 × 2^6 = 20 × 64 = 1,280 base points. Each win type then multiplies the base and rounds the payment up to the nearest 100:
- Non-dealer tsumo — dealer pays2 × 1,280 = 2,560 → rounds up to 2,600
- Non-dealer tsumo — each non-dealer pays1 × 1,280 = 1,280 → rounds up to 1,300
- Dealer tsumo — every player pays2 × 1,280 = 2,560 → rounds up to 2,600
