Training Modes - Tenpai · Discard · Shanten · Yaku
Start any focused drill from this hub. Each mode trains one core skill—build tenpai and shanten recognition first, then move to discard and one-shanten decisions, or practice identifying every hand-inherent yaku.
Suggested path: Shanten → Tenpai → One-shanten acceptance → Discard → One-shanten discard → Yaku recognition. Or jump straight to the mode you want to improve.
