Mahjong Score Calc II is a powerful calculator with 4 core features:

2. Score practice quizzes (han/fu input and point input modes)
3. Effective tile calculation for any 13-tile hand (draw, call)
4. Tile efficiency quizzes (best discard, best draw, best call, effective tiles)

This app is a complete upgrade to the score calculator tools that have long existed for riichi mahjong. Whether you can't figure out your waiting tiles, or want to know exactly how many points each draw is worth — calculate it all at once.

Easily look up effective tiles during a game, while reviewing a hand record, or during a post-game discussion with friends.

You can also check which meld would have been the best move. Infinite auto-generated "best discard" quizzes let you study mahjong anywhere — even on your commute.
