Mahjong Helper

Mahjong is an enjoyable game, played around the world. However, for beginners (and even more experienced players!), calculating the value of a hand can be confusing. In addition, determining point exchanges between players after the value of each hand is calculated can also be tricky.

Mahjong Helper aims to simplify the tasks of scoring and exchanges. It can also be used to keep a history of matches played, and to easily experiment with different methods of scoring.
