Complete guide to point calculation in Riichi Mahjong

Base Points Formula

Points in Riichi Mahjong are calculated from han (yaku value) and fu (minipoints).

Base Points Formula:

base = fu × 2^(han + 2)

The base points are multiplied by different factors depending on dealer/child and ron/tsumo.

When base points exceed 2000, limit hands apply instead.

Final points are calculated by multiplying base points:

Role	Ron	Tsumo
Dealer	base × 6	base × 2 (from each)
Child	base × 4	base × 1 + base × 2 (child + dealer)

All values are rounded up to the nearest 100.

When han reaches certain thresholds, fixed point values (limit hands) are used instead of the formula:

han	Limit	Base	Dealer Ron	Child Ron
5	Mangan	2,000	12,000	8,000
6-7	Haneman	3,000	18,000	12,000
8-10	Baiman	4,000	24,000	16,000
11-12	Sanbaiman	6,000	36,000	24,000
13+	Yonbaiman	8,000	48,000	32,000
Yakuman	Yakuman	8,000	48,000	32,000

Mangan also applies to 4 han 30+ fu and 3 han 60+ fu.

Here are some practical calculation examples:

1 han30 fu

Base = 30 × 2^(1+2) = 30 × 8 = 240

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 1,500	+1,500
Dealer	Tsumo	Child ×3: 500	+1,500
Child	Ron	Discarder: 1,000	+1,000
Child	Tsumo	Child ×2: 300, Dealer: 500	+1,100

2 han30 fu

Base = 30 × 2^(2+2) = 30 × 16 = 480

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 2,900	+2,900
Dealer	Tsumo	Child ×3: 1,000	+3,000
Child	Ron	Discarder: 2,000	+2,000
Child	Tsumo	Child ×2: 500, Dealer: 1,000	+2,000

2 han50 fu

Base = 50 × 2^(2+2) = 50 × 16 = 800

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 4,800	+4,800
Dealer	Tsumo	Child ×3: 1,600	+4,800
Child	Ron	Discarder: 3,200	+3,200
Child	Tsumo	Child ×2: 800, Dealer: 1,600	+3,200

Mangan

5 han30 fu

Base = 30 × 2^(5+2) = 3840 → Mangan (2000)

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 12,000	+12,000
Dealer	Tsumo	Child ×3: 4,000	+12,000
Child	Ron	Discarder: 8,000	+8,000
Child	Tsumo	Child ×2: 2,000, Dealer: 4,000	+8,000

Haneman

7 han30 fu

Base = 6-7 han → Haneman (3000)

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 18,000	+18,000
Dealer	Tsumo	Child ×3: 6,000	+18,000
Child	Ron	Discarder: 12,000	+12,000
Child	Tsumo	Child ×2: 3,000, Dealer: 6,000	+12,000

2 han25 fu

Base = 25 × 2^(2+2) = 25 × 16 = 400

Chiitoitsu always uses fixed 25 fu (no rounding)

Winner	Type	Payment	Total
Dealer	Ron	Discarder: 2,400	+2,400
Dealer	Tsumo	Child ×3: 800	+2,400
Child	Ron	Discarder: 1,600	+1,600
Child	Tsumo	Child ×2: 400, Dealer: 800	+1,600

💡 Memorize common values: 1 han 30 fu = 1000/1500, 2 han 30 fu = 2000/2900, 3 han 30 fu = 3900/5800

💡 Know the limits: 5+ han = Mangan (8000), 6-7 han = Haneman (12000), 8-10 han = Baiman (16000)

💡 Dealer pays 1.5x: Dealer points are always 1.5x the child points for the same hand
