Reporting a bug? Including your device model, your OS version, and what you were doing when it happened will usually save us a round of questions.
Each puzzle is a grid of numbers. Trace a path from the entry to the exit by dragging your finger across the grid. The numbers along your path combine to make a running total, and your goal is to finish on the target shown at the top of the screen.
Paths follow the openings between cells, and cannot cross themselves. If a move is refused, there is either a wall in the way or you have already visited that cell. Lift your finger to start again.
Hints reveal part of the solution. You get up to three per puzzle, and each one used reduces your score for that level.
Your score combines a base score for the level with a time bonus, minus a penalty for each hint used. Finishing quickly and without hints earns three stars.
No. You can play everything without registering. An account lets your scores appear on the leaderboard and keeps your progress if you change device.
Progress is stored on the device you played on. If you played without an account and then signed in on a different device, the original device still holds that progress. Email us if scores are missing from a device you have signed in on.
In the app, go to Profile and choose Delete account. This removes your sign-in record, every score we hold for you, and the progress cached on that device. It cannot be undone.

Write to support@playnumble.app and tell us what happened. We would rather hear about a problem than have you delete the app.
