Rubik's Cube 4X4
Just in case the original 3x3 was a bit too easy for you, take on a proper challenge with the 4x4!
Twist and turn the sides to rearrange the colored squares until each side matches. Sounds simple, but with 7.4×1045. / 7.4 quattuordecillion possible permutations yet only one solution, which is an unfathomable number, it may take some time! Unlike the 3x3, the 4x4 doesn't have a fixed middle tile, so any colour can go anywhere!
These cubes are now stickerless - If anyone ever tells you they solved the Rubik's Cube by picking the stickers off - hand them one of these. The traditional stickers have been replaced with plastic tiles, which means no fading, peeling or cheating!
