How to play
Goal
Make three sets from your 9 tiles before the CPU does. A match is four hands (East 1, East 2, South 1, South 2); the higher score wins.
Tiles
Each of the 18 countries has three tiles, numbered 1 to 3, showing its landmark. The colour tells the region. There are 3 copies of each tile and 4 Globes, which stand in for any tile.
123Sets
- Triplet: three of the same tile. 222
- Route: one country's 1, 2 and 3. 123
- A Globe can replace one tile in a set. 13
A turn
- Draw a tile, then discard one. If your hand is complete after the draw, you can win (Tsumo).
- When the CPU discards: Ron to win with it, Pon with two of the same tile in your hand, or Chi with two tiles of the same country that make a Route with it. After a call you discard without drawing.
- Riichi is automatic: once you are one tile away, it is declared, and from then on every drawn tile that does not win is discarded for you. You can still win by Ron.
- When the wall runs out the hand is a draw; the side that is one tile away receives the no-ten payment.
Hands and dealer
The dealer alternates. If the dealer wins, or is one tile away when the wall runs out, the same hand is played once more (renchan). A tied match gets one extra hand.
Controls
- Tap a tile to discard it, or use ← → to pick a tile and Enter to discard it.

- Before each match, choose the CPU level, voice (calls and yaku read aloud in English) and language, then press Start (or Enter). Your choices are kept for next time.
- During a match, the gear button opens the same settings. Save applies your changes (a new CPU level from the next match) and Cancel leaves them as they were. End match leaves the current match.

Yaku and points
Every yaku the winning hand qualifies for adds up. The score is the points × 100, taken from the other player. Yakuman are worth 30 points each and replace all other yaku.

Countries and landmarks
The 18 countries come from six regions, three countries each: Asia, the South Pacific, Europe, Africa, North America and South America. Each tile's colour is its region.
