Mahjong
Standard Japanese riichi mahjong. Completion demands 10 wins, 5 Mangan, 1 Haneman, a Riichi Ippatsu, and a Full Straight — one of the series' biggest walls.
- Keep your hand fully closed (never call Pon/Chi) — you need that to declare Riichi, and Riichi Ippatsu / Mangan come from closed hands.
- Default to Tanyao (only simples 2–8); for the Full Straight target, chase a 1–9 run in a single suit.
- Riichi Ippatsu means winning within one go-around of declaring — reaching tenpai fast is the only way to farm the luck for it.
- Before a game, in the rules menu turn OFF the 2-han minimum and turn ON Red Dora: dropping the 2-han rule lets cheap one-han hands win (fast for the 10-win count), and each red 5 is a free extra han toward Mangan/Haneman.
- Farm the Full Straight (Ittsu) with an OPEN hand — the 123/456/789 are three separate melds, so you can Chi opponents' discards to complete them rather than drawing all nine yourself. Only commit when your opening deal already holds 5+ of one suit.
- The Lucky Tile item in Coin Locker I2 hands you Thirteen Orphans (a yakuman) for a free big-score win, but the yakuman overrides normal scoring so it does NOT count for the Riichi Ippatsu requirement — get Ippatsu the normal way.
