📖 How to Play
- From 13 tiles, draw and discard one toward 4 sets + 1 pair
- Call Pon/Chi/Kan on discards; declare Ron on a winning discard
- A closed tenpai hand can declare Riichi (1000-pt bet, ura-dora chance)
- Self-draw your winning tile to Tsumo — you always need at least one yaku
- Tap a tile then tap again to discard; Tsumo/Ron/calls are buttons
- East round (E1–E4); final scores set your placement and feed the leaderboard
