Pick the fu after rounding up to the next 10. Seven pairs is always 25.
Fu change the payment only from 1 to 4 han. From 5 han up, every hand is a mangan or more. Check any hand in the score calculator.
How to use
- Pick a question. Count the fu asks for the fu total. Score the hand lists the yaku and asks what the hand pays.
- Read the hand: the tiles you held, the winning tile, any calls, ron or tsumo, your seat and the round.
- Tap your answer. The reveal splits the hand into sets and a pair and adds the fu one line at a time.
- Your score and streak stay in this browser, one tally per question type.
How it works
Each hand starts as four sets and a pair, or as seven pairs. The quiz keeps it only when the winning tile finishes it one way, so there's one wait and one right answer.
The fu come from the counter inside the score calculator: 20 to start, 10 for a closed ron, 2 for a tsumo, then triplets, a value pair and a middle, edge or pair wait, rounded up to the next 10. Pinfu tsumo is 20. Seven pairs is 25.
A triplet you finish by ron counts as open. The hand still counts as closed, so it keeps the 10 fu for a closed ron.
Closed hands declare riichi. Open hands always hold a dragon or wind triplet that scores. Dora are given as a count. Payments use the same table as the calculator, with kiriage mangan off and no honba or sticks.
Some hands are left out on purpose: kans, and a pair of your seat and round wind, which some rule sets pay 2 fu and others 4.
Counting is the easy part
Knowing when a cheap hand is worth the risk wins more games. I coach that over your own Tenhou or Mahjong Soul logs.
