RIICHI ORBIT: Mahjong

Start with your first tile. Learn Japanese riichi mahjong through guided lessons, then practice against AI at your own pace. RIICHI ORBIT brings a four-player mahjong table to your iPhone or iPad. Play solo against three AI opponents, with no turn timer and advice when you need it. English and Japanese are both supported. You can also equip special abilities for Orbit matches, with 10 skills to discover. LEARN BY MAKING THE MOVES You don't need to know the rules before you start. Join Mio, a fellow beginner, and Noa, your space navigator. Tap the tiles and play through guided situations while Noa explains what happens. Explore guided lessons, from the basics to advanced hands and scoring: • Recognize the tiles, take turns, and build a winning hand. • Learn yaku: the patterns and conditions a hand needs to win. • Try riichi and calls, and learn how furiten and defense work. • Understand scoring with worked examples and practice questions. Return to completed lessons whenever you want a refresher. Start small, and keep learning as you play. A FRIENDLY TABLE ON EARTH Put what you've learned into practice at the Earth Cadet Table. Choose three opponents from five friendly creatures and play against gentle AI with advice available throughout the match. No in-game currency is needed. Try Photon Barrier to stop rivals from winning on your next discard, and earn creature cards as you improve. PLAY SOLO, THINK AT YOUR OWN PACE Already know the rules? Head straight to the Moon. Play East-only or East–South matches against Orbit AI. Ask your navigator for a suggested discard and the reasoning behind it. Advice uses your hand and information visible at the table.
