## Description

Practice riichi mahjong one hand at a time.
No opponents, no timers — just a solo riichi trainer built around a single problem a day.
The steps you take become the tiles you draw, so your hand grows without you rushing it.

■ Today's Discard — one problem a day

Each morning a hand arrives. All you do is pick the tile to cut.
Once you answer, the numbers behind every candidate open up: expected value,
tile acceptance, shanten, win rate and tenpai rate.
You see why that discard was the one, and instinct turns into something you can explain.
Answer correctly and you earn bonus draws for the day's game, and your streak grows.

■ Practice Mode — sets of five

For the days you want to sit down and drill. Every question comes with an
explanation, and the ones you miss are kept for review.

■ Today's Game — steps become draws

Mahjong Walk reads your step count from iPhone or Apple Watch. 100 steps, one draw.
Start from a 13-tile hand and try to win within 30 draws.
Everyone plays the same wall each day, and when you finish you can see what others
did with it: the fastest win, the highest score, the most popular discard each turn.
There are no rankings. It is a record of the shape your day took, not a competition.

■ Also included

- History calendar: the days you walked and the days you won, at a glance
- Discard review: replay past rounds and look for the better choice
- Real-time shanten, expected value and useful tile display
