Tetrahedral shaped brain teaser starts looking like a pyramid but quickly changes with each turn. Twist to change shape & color, then solve to get all sides the same color! - Internal spherical spring construction allows for smooth turning. - Colored plastic sides remove issue with moving stickers. - Challenge yourself, challenge your friends!
We ordered it and kids were excited for two days and played it nonstop. However, My 7 and 5 would occasionally get annoyed while one playing the other bugging. Therefore, it turned out to be more challenging. Nevertheless, it provides my kids great chance practicing respect, turn taking, and resistance on facing challenging pieces.
