About

Fuyomi works out the score of a riichi mahjong hand and shows you why. Enter the tiles, calls and dora, tap tsumo or ron in the sentence under the hand, and the payment appears the way it is announced at the table, with fu and han broken down piece by piece. When a hand can be read more than one way, Fuyomi picks the higher reading and shows the one it set aside. When the result depends on a table rule, it says so and shows the other value. Three rule presets cover the common house rules, and nine settings let you match your own table, from red fives and open tanyao to rounding up to mangan and counted yakuman. The trainer asks you to announce the payment yourself, as an amount, not as a multiple choice. When the cause of a wrong answer is clear, such as a forgotten honba or a missed fu for the wait, Fuyomi names it and opens the card that explains the rule. Beginners start with easy hands and see the card right after a mistake. The table tab keeps score for four players. The payment from a calculated hand goes straight into the game, a draw settles the tenpai and noten payments, and the final result applies the placement points of your preset. The total is checked after every entry. Hand scoring, rule presets and the explanation cards are free for good. The trainer gives you five answered problems a day at no cost. Fuyomi Plus removes the daily limit and lets you start new table games. A game already in progress can always be finished. Plus is a one-time purchase or a yearly subscription. There are no ads, and Fuyomi handles only points, never money.
