- If below 5 han, also choose the fu (5 han and above use a fixed score regardless of fu).

FAQ
Why can't I select fu sometimes?
At 5 han or above (mangan and up), the score is fixed regardless of fu, so the fu input is disabled.
How is the score calculated?
Base points = fu ร 2^(2+han), capped at the mangan base (2000) if it exceeds that. From there, ron pays 4ร the base (6ร for the dealer), and tsumo has non-dealers pay 1ร the base each and the dealer pay 2ร (or all three pay 2ร if the dealer wins) โ each payment individually rounded up to the nearest 100.
What fu values can I choose?
20, 25, 30, 40, 50, 60, 70, 80, 90, 100, or 110 (25 fu is used for specific hands like seven pairs).
