麻雀計算機I ~麻雀の点数計算と得点管理~

Downloaded over 150,000 times on iPhone — it's the most popular Mahjong app in Japan! Say goodbye to the hassle of manually exchanging points after every round. Easily track score changes during gameplay and manage detailed match records with advanced analysis features.

The Mahjong Calculator eliminates the tedious process of point management that often comes with hand-built Mahjong games.

By simply entering the results of a Riichi, Furo, or Ron, the app automatically manages the overall score while recording each calculation. This allows for precise tracking of game statistics and match history.

・ Easy to Use!

Just tap on the score of the winning player and follow the intuitive steps. Even additional sticks such as dora and reach deposits are automatically calculated!
