The Rubik's Colour Block is a Rubik's Cube with an interesting twist… In it's solved state, Rubik's Colour block resembles the classic 3x3 Rubik's Cube. However, that's where the comparisons end. The Colour Block's unique mechanism and different sized layers result in the cube completely changing shape with every move you make, resulting in confusion and a real challenge to solve! Rubik's Block is the fun strategy game for 1 player, ages 8 and up.
