## Description

New to mahjong? Start with the tiles, learn by playing through guided lessons, then practice with friendly AI rivals. Lessons and in-game advice are now in English.

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.

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 57 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.

MEET RIVALS AND COLLECT THEIR CARDS
Finish above a rival to earn their creature card. Collect rare rewards to unlock SSR cards and view each creature in 3D. Rotate, zoom, and explore the details, from patterned wings to decorated shells. Special cards also record your yakuman achievements.

EXPLORE BEYOND EARTH
Earn Lumina, the in-game currency, through regular matches and challenges. Meet each route's requirements to reach new planets and rivals. Star Crown Matches let you choose your opponents for a tougher challenge.

REVISIT A DECISION
Review saved matches, inspect hands and discards, and try a different move from a saved position. Lessons and AI matches work offline. Content updates, optional rewarded ads, purchases, and save transfers require an internet connection.

MADE FOR IPHONE AND IPAD
Play in portrait or landscape. Switch between English and Japanese anytime in Settings.

Free to play, with optional rewarded ads and in-app purchases. Lumina purchases replenish in-game currency; they do not buy cards, guarantee wins, or bypass route achievement requirements. Cards are collectible rewards with no gameplay bonuses or cash value. You never wager cards or money.

Moving to a new device? Create a transfer code in Settings to move your cards, progress, and remaining Lumina. Codes last seven days; replay files do not transfer.
