Sharpen your riichi mahjong skills, one tile at a time. Mahjong Tsujigiri! turns discard decisions and fu calculation into short practice sessions. Each round lasts 60 seconds: choose a discard or answer a four-choice fu question, then review what you missed. THREE WAYS TO PRACTICE • Full Flush: advanced discard puzzles using a single suit. • What to Discard: build efficient hands with no separate question timer inside the 60-second round. • Fu Practice: read a completed hand and calculate its fu, with a detailed breakdown to review afterward. ONI CHALLENGE Add a five-second limit to each question in any mode. Consecutive correct answers double the points, up to 8×. Keep your streak alive! KEEP IMPROVING • Review accepted discards, explanations, and fu breakdowns. • Track your history and best score on your device. • Climb samurai-inspired ranks and compare scores on all-time, weekly, and mode leaderboards. • Learn from guides on tile efficiency, full-flush waits, fu, and terminology. • Switch between Japanese and English in the app. The free plan includes 5 plays per day. Premium offers unlimited play, no ads, and new problems added monthly through a monthly or annual auto-renewing subscription. A separate one-time Remove Ads purchase removes ads without removing the daily play limit. Prices are shown in your local store. Manage or cancel subscriptions in your App Store account settings. You can restore eligible purchases in the app. This is a riichi mahjong training game, not a tile-matching solitaire game. There is no wagering or real-money gambling.
