A simple strategy involves solving the inner 1×3 bar made of two edge centers and the middle center, then creating the outer 1×3 bars made of two corner centers and an edge center and attaching these to the first 1×3 bar. The 5×5 has three different types of center pieces that can’t be interchanged, including the middle-fixed, corner, and edge centers. This means the centerpiece that lies directly in the middle of each side denotes the final color of that side. Unlike the 4×4, the 5×5 and all other odd-layered cubes have fixed center pieces. The first step to solving the 5×5 involves completing the centerpieces. To solve the 5×5, follow the steps below: The best part about a 5×5 is that there are no special or parity cases, making it easier to solve than a 4×4. It essentially involves ‘reducing’ the cube to a state that can be solved as if it were a 3×3 cube by solving the centerpieces and pairing up the matching edge pieces. It’s suitable for beginners and people participating in speedcubing competitions in the 5×5 category.

The Professor’s Cube is a 98-piece puzzle that can be challenging to complete, but it is doable if you carefully follow the reduction method algorithm.

The 5×5 Rubik’s cube is also known as the Professor’s Cube because of its high difficulty level.
