麻雀.AI is an Android application that uses AI to recognize and calculate scores for winning hands in Mahjong. By taking a photo of the winning hand, the app can identify the tiles and calculate the score based on the rules of the game. The app includes the "Kuitan" rule and "Suanko" scoring.

To use the app, simply tap on the "Ron" or "Tsumo" button on the screen and the app will provide the result in about 6 seconds. For concealed Kong, please reveal the two ends or two middle tiles and place them in the hand.

Please note that the app may not recognize the tiles accurately and the processing time may take longer than 6 seconds depending on the server load. The interface may also be improved in future updates, and the app will periodically learn and improve its recognition accuracy.
