Contact support

Email info@toolsbase.org. Please include your device model, operating-system version and a short description of the issue. Screenshots are welcome when helpful.

Quick troubleshooting

Update Number Grid to the latest version available in your app store.
Close and reopen the app if a puzzle does not load or respond.
If you think a puzzle has no valid answer, note its level and grid; it helps us check it.
