Solve the yellow centers the same way you solved the white ones while keeping the white ones intact using insertion techniques. This part is pretty intuitive, you just have to make two 2x1 blocks and pair them together! Move on to the opposite side after that, which is yellow in this case. Move the 4 center pieces around so that you form a 2x2 block of white on one side. Start with any color, let’s choose white. The ultimate goal here is to make the 4x4 behave like a 3x3 so that we can apply familiar strategies. The most widely used technique to solve the 4x4 Rubik’s Cube is the 'Reduction Method', which breaks down the puzzle into manageable steps.
It also introduces the possibility of parity errors, which are situations where only one or two pieces are out of place, which does not happen in normal 3x3 cubes. This means orientation matters even for the centerpieces. Unlike the 3x3 cube, the 4x4 doesn't have fixed centers. However, with patience and a clear approach, you can easily learn how to solve it! Let's dive into learning how to solve the 4x4 Rubik's Cube.
With its added complexity, the 4x4, also known as Rubik's Revenge, presents new challenges. The journey from the 3x3 to the 4x4 Rubik's Cube can be daunting.
