Walk to draw tiles! Janpo is a step-tracking app designed for Mahjong lovers.

■ How to Play:
Walk
Janpo reads your step count from your iPhone or Apple Watch. You earn 1 tile draw for every 100 steps.
Draw (Tsumo)
Start with a 13-tile starting hand and use your earned draws to pull new tiles one by one.
Discard (Kiru)
Choose one tile to discard from either your drawn tile or your hand. The app displays available winning tiles (Yoko-hai), making it safe and easy for beginners.
Win (Agari)
Form valid Yaku (hands) to complete a 14-tile winning hand. Start with beginner-friendly hands like Riichi or Tanyao (All Simples).
Exhaustive Draw (Ryukyoku)
If you cannot complete your hand within 30 draws, the round ends in a draw.
