02Frequently asked questions
How do I play?
Tap a mirror, splitter or prism to turn it; drag a movable piece onto an empty tile to move it. Make every target receive light of exactly its colour. Pieces with a small dot are fixed.
I'm stuck on a level.
Every level is verified solvable. A hint (10 lumens) places one piece correctly. If you are out of lumens, you can watch a short optional video for a free hint (up to 5 per day). Luminary Pass owners get the first hint free on every level.
Why are later levels so hard?
Difficulty rises level by level: pieces start scattered, some pieces are decoys you don't need, and later worlds use two separate beams. Every tenth level is a Trial with double rewards.
My purchase did not arrive.
Some payment methods are confirmed with a delay. Reopen the Game, then tap Restore purchases in the Store or Profile. If it still does not arrive, email us with your order number.
How do I restore Remove Ads or the Luminary Pass on a new phone?
Sign in with the same Google account, open the Store and tap Restore purchases. Lumen packs are consumable and cannot be restored.
How do I get a refund?
Refunds are handled by Google Play: see Google Play refunds. Your statutory rights are unaffected.
