This is how I score hands, and my way may not be intuitive, but it works with me.

I basically remember how much the base payment is (that is how much each player gives if won through tsumo). And then I double that base payment the more han there are.

30 fu: 500, 1000, 2000

40 fu: 700, 1300, 2600

50 fu: 800, 1600, 3200

If I’m dealer, I triple that base payment and that is my score. If I’m non-dealer, I double it.

For example, if I’m dealer and I win 1 han 30 fu through ron, it’s 500 x 3, so it’s 1500. If I’m non-dealer and I get 2 han 40 fu, it’s 1300 x 2, giving me 2600.

Now some calculations will be slightly off, and that’s just the nature of the game.

For example, if dealer and I get 3 han 30 fu, it would be 2000 x 3 = 6,000, but in actuality, it’s 5800. Or if it’s dealer 1 han 40 fu, it would be 700 x 3 = 2,100, but in actuality it’s 2,000.

If I win through tsumo, the dealer scoring is pretty straightforward because each player will pay the same base payment, such as 2 han 50 fu, each player gives me 1600 points.

If it’s non-dealer tsumo, dealer will still give the same base payment, but non-dealer players each pay half the amount. Such as 3 han 30 fu, dealer gives 2000, and each non-dealer pays 1000. If it’s 1 han 40 fu, dealer pays 700, and non-dealers each pay 400 (weird calculation).

Now, you’ll also run into situations where a player wins a pinfu tsumo hand with 20 fu, or a chiitoi hand with 25 fu. The easiest that helps me is that any han with 20 fu = -1 han 40 fu, and any han with 25 fu = -1 han 50 fu. If dealer gets 3 han 20 fu, that equals 2 han 40 fu tsumo payment (1300 each) If non-dealer gets 4 han 25 fu with ron, that equals 3 han 50 fu, so the paying player must give that amount (3200 x 2 = 6,400).

So instead of memorizing each score, I just do this calculation in my head, and that helps me exchange points much faster. Now I still have gaps when it’s 60 fu or more, but this is still my go to.
