Mahjong Fold Dojo is a training app that helps you quickly judge which tile is the safest to discard after an opponent declares riichi.
You can repeatedly practice core defensive concepts such as genbutsu, suji, kabe, outside tiles, and honor tiles through quiz-style exercises.
・Practice Mode: Solve mixed questions in a match-like flow
・Learning Mode: Focus on specific defensive themes
・Weakness Review Mode: Retry only the questions you missed
・Result Screen: Compare the risk level of each candidate tile to deepen your understanding
・Time Limit Settings: Adjustable from unlimited time to short timers
From beginners who want to reduce deal-ins to intermediate players who want to sharpen their defense, this app helps strengthen fold-or-push decision-making through short daily practice sessions.
