Superclick Cube is a cube with sixteen 12.7 mm diameter spherical magnets. There are placed in the corners and core. As each pair creates a force of 2.9 kilogram, making a turn requires 4 x 2,9 = 11.6 kg of force to the solver. This makes the puzzle good for training practices for speed cubing as it trains the muscles, but requires good dexterity at the same time.
