Mahjong Riichi Calculator

Mahjong Riichi Calculator works out the score of a Japanese Riichi Mahjong winning hand for you — han, fu and the final points — so you never have to argue over the count again. Two ways to enter a hand: • Scan it — point your camera at your winning tiles and the app detects them on your device. Tiles are sorted automatically so you can quickly fix any misread. • Enter it by hand — tap to add tiles in a fast, drag-and-drop editor. Then the app: • Splits your hand into its sequences, triplets, pairs and quads • Lets you mark called (open) melds and the winning tile • Asks the usual questions — Riichi, Tsumo, Ippatsu, dora, round/seat winds and more • Shows the full breakdown: every yaku, the fu count, and the points to pay It handles the tricky cases correctly — seven pairs, thirteen orphans, the yakuman, pinfu, sanshoku, pure straight and proper rounding — using a faithful implementation of standard Riichi scoring. Everything runs entirely on your device. No account, no internet needed to score a hand, and nothing about your hands or photos is collected, stored or shared. Perfect for players learning to count, settling end-of-hand scores quickly, or checking their own math.
