Getting help

If something is not working as expected, try the common fixes below. We do not list a public email address on this website.

Update to the latest version of Numbr from the App Store.
Restart the app if audio, ads, or Game Center views do not load.
Check your internet connection for ads, Game Center leaderboards, and external links.
Check iOS Settings if Game Center, iCloud, notifications, or advertising preferences need changing.

Drag digits and operators from the tray onto empty cells so every row and column evaluates correctly.
Multiplication and division resolve before addition and subtraction. Division must be exact.
Use Undo to reverse the last placement. Drag a placed piece back to the tray to remove it.
Submit only when the grid is full. Incorrect submits keep you on the same puzzle.
Use Training to practise without affecting Daily Challenge leaderboards.
Set your display name and avatar in Settings so you appear consistently on ranks.

Eligible Daily Challenge scores can post to cloud leaderboards when iCloud is signed in. Game Center may also be used for global boards.

Create a group: open Ranks → Private → Create, choose a name and optional group avatar, then share the invite code.
Invite friends: share the short code or invite link from Manage.
Manage members: admins can remove players or allow them back; anyone can leave from Manage.
Join: tap Join and enter a friend’s code, or open a numbr:// invite link.
