OS Cube by Ilya Osipov (white body & blue tiles)

Size : 66x66x66 mm
Color : white body & blue tiles

The OS Cube is designed by Ilya Osipov, and the award-winning puzzle in Nob Yoshigahara Puzzle Design Competition 2021. 
This puzzle is a toroidal twisty puzzle with magnets. Opposing magnets can attract or repel. The object is to twist the puzzle such that all magnets attract. The tactile and acoustic sensation of Ilya's design is fantastic, with the magnets clicking under your fingers.

It works like a 2x2x2 cube. It is not solved by arranging some colours this puzzle which does not have. Every tile can be retracted or extended. This is done by turning the puzzle and thereby rearranging some internal magnets. The puzzle has two solutions: All tiles extended and all tiles retracted.
