Description
No need to input Mahjong tiles one by one manually.
Riichi Mahjong Helper is an app that uses AI image recognition to identify your tiles when you take a photo of your hand along the on-screen guide. It helps you easily check your waits (machi) and calculate your winning scores.
■ Key Features · AI image recognition-based Mahjong tile detection · Check the Tenpai status of your photographed hand · Display winning waits (machi) when in Tenpai · Calculate Yaku, Han, Fu, and the score for winning hands · Distinguish between Tsumo and Ron · Support for open tiles (calls) like Chii, Pon, and Kan · Replace incorrectly recognized tiles · Manually add unrecognized tiles · Delete falsely detected tiles
■ How to Use

If any tiles are recognized incorrectly, manually replace or add them.

■ How to Photograph for Score Calculation When calculating a score, please place the winning tile in a separate area to the right of your hand. · Vertically placed winning tile: Tsumo · Horizontally placed winning tile: Ron You can check the final score by inputting additional necessary information such as Prevalent Wind, Seat Wind, Dora, and Riichi status.
