In this video my brother, Lucas, explains how the PrimeCuber works. He built the PrimeCuber using Lego Spike Prime. The PrimeCuber can solve Rubik’s cubes. We tested many types of cubes and it solves only regular 3x3. We tested a special version of 3x3, regular 2x2, and regular 4x4 but it does not solve it. It only solves these other cubes when they are mixed in very few turns.
