Riichi Mahjong Tile Efficiency Trainer
Basics Course — 30 original discard puzzles. Pick the tile that gets you to Tenpai fastest.
About this course
- Who it is for: beginner to intermediate Riichi Mahjong players who want tile efficiency to become automatic.
- How the answer is decided: for every possible discard we count the tiles left in the wall that would move your hand one step closer to Tenpai on the next draw (ukeire). The discard with the most tiles is correct; ties are all correct. Every answer is computed, not guessed.
- Not considered in this course: points, Dora and Yaku; how good your final wait will be; shapes two steps ahead; the table (discards, opponents, safety); Seven Pairs and Thirteen Orphans.
Which tile do you discard?
Tap a tile to select it, then press Discard.

“Steps back” means the discard moves the hand one step further from Tenpai, so its tile count is not comparable.
