If a regular Rubik’s Cube just isn’t enough of a challenge anymore, try the 4x4 cube, also known as the Rubik’s Master Cube. The common moves and algorithms used to solve a regular Rubik’s Cube will not work on the 4x4, so you’ll have to start fresh! It also has no fixed center pieces, so there are no freebies on this puzzle.
