Rules and help
What is the goal?
Light all crystals at the same time. Rotate and slide mirrors and work with prisms, filters, portals and gates.
How do I control the game?
Tap to rotate a mirror. Swipe to move a sliding mirror. Pinch with two fingers to zoom; drag to rotate the room.
What if I get stuck?
Use Undo for any move. There is no timer and no penalty. Enable Easy Mode in Settings for hints. Levels solved with hints are marked.
How do I distinguish colours?
Colour-blind mode adds symbols and patterns.
Which worlds are free?
The app and the first two worlds, Lighthouse and Observatory, are free: 100 levels. Crystal Cave, Hall of Mirrors, Glass Cathedral and Sky Observatory each contain 50 levels and are separate one-time in-app purchases at €0.99 each. No subscription, no ads.
How do I restore a purchase?
On a world’s purchase page, choose Restore purchase using the Apple Account that made the purchase. Buying and restoring purchases require an App Store connection.
Can I play offline?
Yes. The daily puzzle is also determined entirely offline from the date. Opening this website requires internet access.
How do I delete my progress?
Delete the app in iPhone Settings. Offloading keeps its data. Manage device backups separately; restoring a backup may restore game data. Deleting the app does not remove Apple’s purchase history.
Need more help?
Email us with the affected level, your iPhone model, iOS version, app version and a short description if helpful. Please do not send passwords, complete purchase receipts or payment details.
