Take on a bigger challenge with the Rubik's 4x4 Master Cube, also known as Rubik's Revenge. This classic logic puzzle has four layers on each face, creating a more demanding solve than the original 3x3 cube. Twist and turn the colourful faces to mix the pieces, then use logic, memory and problem-solving skills to return each side to a single colour. The cube's moving centre pieces add an extra layer of strategy, making it a rewarding choice for experienced cubers and anyone ready to progress beyond a standard Rubik's Cube. The 4x4 Master Cube is suitable for players aged 8 years and over, and is a great way to improve concentration and problem-solving skills. Whether you're looking for a compact brainteaser or a new challenge, the 4x4 Master offers a substantial new challenge in the iconic Rubik's range.
