Cube Flip Unblocked:

Cube Flip is a simple, yet mentally stimulating game that takes inspiration from classic grid puzzle games. The game features gradually increasing difficulty levels that challenge your mind and keep you focused. The visuals and the soundtrack enhance your experience while playing.

This means that you have to rotate and flip the cube to make the colors on each side of the cube match. It isn’t easy initially, but it gets easier as you keep playing.
