RIICHI ORBIT: Mahjong

Play riichi mahjong with space creatures and special powers. RIICHI ORBIT is a mahjong adventure for solo play and online friend matches: read your rivals, collect their cards and travel from planet to planet.

INVITE FRIENDS WITH SIX DIGITS
Share a six-digit invitation number to play regular or Orbit matches with three or four players. Orbit AI fills empty seats, and your friends’ crew appearance and accessories appear at the table. Choose 10, 20 or 30 seconds, one minute or five minutes per decision. Friend matches require a connection.

A NEW LAYER OF STRATEGY
Protect your next discard from ron, or restart the hand and choose between two starting hands. In Orbit matches, timing your limited abilities is part of the challenge—and rivals use powers too.
Finish your first regular match to unlock Orbit. Regular mahjong without powers is also available.

LEARN AND PLAY AT YOUR PACE
Solo matches have no turn timer. When you need a hint, Orbit AI suggests tiles and explains why. New to mahjong? Your support partner guides you from the basics through free Earth practice to your first Moon match. Know the rules already? Start with a match.

COLLECT, CUSTOMIZE, EXPLORE
Earn space-creature cards through matches and fill your collection. Cards are never lost after a defeat. Create your character, furnish your spacecraft cabin with planetary items and play at your own table. The shop also offers free items to claim.

Core matches and bundled lessons work offline. No sign-in required. Available in Japanese and English on iPhone and iPad.

OPTIONAL ADS AND IN-APP PURCHASES
You can earn Lumina through free play. Ad viewing and purchases are optional. Keep purchased concentrated Lumina, spend it on exclusive decorations or convert only what you need into regular Lumina. There is no wagering of cash or cards.
Currency balances are stored on your device with no expiry. To change devices, use a seven-day transfer code from Settings; replay files do not transfer. Purchase history alone cannot restore remaining balances. Content updates, ads, purchases and save transfer require connectivity.
