RUBIK’S 4×4 Sometimes known as RUBIK’S REVENGE it is the 4×4×4 version of the famous 3×3 Rubik’s Cube Following on from the fantastic response with the launch of our 3×3 Cube with tough tiles and a smoother mechanism Rubik’s decided to give the same treatment to the 4×4. This is a new welcome challenge for those of you clever enough to have mastered the original Cube. The new 4×4 is slicker faster and more robust due to the all new design. The puzzle is made up of 56 small cubes on the surface. However unlike the 3×3 Cube the centre pieces can move in relation to each other making it even more difficult to solve than the original. For those who struggle to master this challenge – or simply lack the patience – just look up the easy to follow Solve it Guides online at the Rubiks website.
