Cubix Support

A question, a problem or an idea?

Write to us

Tell us your phone model, your iOS or Android version and what happened, so we can give you a more accurate answer.

A purchase doesn’t show up

Check that the payment went through in the App Store or Google Play, then restart Cubix: the hint tokens and gems you bought are added automatically, even if the app closed during the payment.

Getting your purchases back on a new phone

Open the Shop and tap “Restore purchases”, using the same Apple or Google account you made the purchase with.

The online duel can’t find an opponent

Online duels need an internet connection and another player searching at the same time. You can also invite a friend with a code, or play against the robot.

My username is rejected

Your username is visible on the leaderboard and in duels. It must be between 3 and 20 characters long and must not contain any rude or inappropriate words. Choose another one, without your full name or any personal information.

My progress has disappeared

Your progress is saved on your phone. It is deleted if you uninstall Cubix or clear its data.

Report a bug

Tell us the game mode, the cube size and what you did just before the problem, and attach a screenshot if you can.

Delete your data

The steps are explained in the privacy policy.
