Project overview
Riichi Mahjong Calculator analyzes hand efficiency, open-hand choices, winning hands, and scores from han and fu. Its default rules follow Mahjong Soul and Tenhou conventions with some customization. Tile inputs can be recognized from images or the clipboard, with the recognition model tuned for Mahjong Soul screenshots. Calculations run locally, and builds are available for web, Android, desktop, and self-signed iOS installation.
