Contact support
For a bug report or question, email the developer. Include your app version, device model, and what happened. A screenshot can help us understand the issue.
How do I solve a puzzle?
Cover the board with rectangles. Each rectangle must contain exactly one number, and its area must equal that number. Rectangles cannot overlap. Open How to Play from the home screen for an introduction, or use a hint when you get stuck.
Can I play offline?
Yes. Puzzles and saved progress work without an internet connection. Advertising needs a connection, but an unavailable ad does not prevent you from playing or using a hint.
Where is my progress saved?
Progress is saved on your device. Uninstalling the app can remove it. The app does not provide account-based progress recovery or syncing between devices.
How do I change my advertising choices?
On iPhone and iPad, choosing Ask App Not to Track disables advertising. You can change tracking permission in Settings → Privacy & Security → Tracking, then restart the app. Where regional privacy options are required, the app provides Settings → Ad Privacy Choices after consent. Read our Privacy Policy for more information.
