A little help.
A clearer path.

Tap an arrow to try to release it. Its path loops around the cube. If another arrow occupies that path, it bumps into the obstacle and costs a life. A clear loop lets the arrow leave. Drag to turn the cube and hold an arrow to trace its route; tracing shows the path, not whether it is clear.

New paths unfold as you progress. The first three levels are available from the start. Earn at least one star in each preceding level to open the next step. Open the Menu to view your Journey, revisit completed levels or select Next step to return to your next unfinished puzzle.

A completion with no mistakes earns three stars. One mistake earns two; two or more earns one. At least one star opens the next eligible level. Replaying a level with a lower result does not reduce your best earned stars.

Open the menu and select Undo to reverse an available successful move. Undo does not refund a mistake or restore a lost life. Use Restart to start the current level again, or Reset view in the menu to return the camera to its starting angle.

No account is needed to play, and puzzles can be played offline. Progress is saved on your device. Advertisements and privacy services require a connection; an unavailable ad does not prevent normal puzzle play. Online accounts, cloud saves and a public leaderboard are not currently available.

First check that you are opening the same app on the same device. If progress is unexpectedly missing, avoid clearing storage or reinstalling before contacting us; doing so may remove local save files. Cubivra does not currently provide an Uzitech cloud-save service, and we cannot promise recovery of deleted device data.

Android app-data clearing, iOS app deletion, switching devices or installing an app with a different package identity can affect local progress. Operating-system backup behavior varies. Let us know the app version and the last level you remember completing.

If all lives are lost and a rewarded ad is ready, you can choose to watch it to continue the same board with three lives. This is available once per attempt. It does not remove mistakes or their effect on stars. Lives are restored only when the ad service reports that the reward was earned; closing an ad alone is not enough.

Ads are not always available. A ready interstitial may appear after every two different completed levels and whenever you choose Try again after losing all lives. There is no three-minute time gate for these placements. If an interstitial is unavailable, the game continues without waiting for it. If an optional rewarded ad cannot load, you can restart the level without watching it. If you completed a rewarded ad but your lives were not restored, contact us with the approximate time, app version and device model. Do not repeatedly tap or click ads to test them.

When required for your region, open Menu → Ad choices to review available choices. Device settings also provide advertising and permission controls. Read the Cubivra Privacy Policy for local save data, Google advertising services and privacy requests.
