About

New to Japanese riichi mahjong? Start with short lessons on tiles, winning hands and the flow of a turn. Then try four-choice questions to check what you have understood. Practice the decisions behind a hand: • Recognize yaku and work through scoring questions. • Identify waits and shanten, and consider which tile to discard. • Read explanations after answering. • Return to wrong answers and bookmarked questions when you want to review. • Follow your learning progress and daily streak. This is a learning and practice app for Japanese riichi rules. It does not promise wins at the table. Learning features are free with ads. An optional one-time purchase removes ads; it is not a subscription. The app is available in English and Japanese.
