FAQ

How do I play?

Tap a plain spot on the wall to shoot a ray. It runs along the grid lines, turns at the corners of the wall and stops when it hits a plain stretch of wall. Whoever draws the fourth side of a square captures it. The player with the most squares wins. Open Rules from the main menu for the full rules.

How do hints work?

Hints are for puzzles and the daily challenge. You get 3 free hints a day; they refill at midnight and unused ones don't carry over. You can also watch a short ad for 3 more hints, buy a hint pack, or buy the unlock, which gives unlimited hints and removes ads between games. A puzzle solved with a hint scores at most 2 stars.

How do I restore my purchase?

Open Settings → Shop and tap Restore purchases. This brings back the unlock on any phone signed in with the same Apple ID or Google Account. Hint packs are stored on the device and cannot be restored, so hints from a pack don't move to a new phone or survive deleting the app. On Android they may come back from your Google Account's device backup.

How do I change my ad privacy choices?

Open Settings and tap Privacy choices. This option appears where consent is required (the EEA, the UK and Switzerland). The app only shows non-personalized ads.

Does it work offline?

Yes. Games against a friend or the computer, puzzles, the daily challenge, saves and statistics all work without a connection. Ads and purchases need a connection.
