Rubik's Professor’s Cube (5x5x5)

Loading..

The Professor's Cube is a 5x5x5 verion of the original Rubik's Cube. The first version of this puzzle was invented in 1986 by Udo Krell, who took a 3x3x3 cube and expanded it.

As with the Rubik's Revenge (4x4x4), the most common algorithm for solving this 5x5x5 cube is called the "reduction" method. Focusing on solving the 3x3 center pieces and 3x1 edge pieces first - thus "reducing" the problem to a 3x3x3 puzzle, which can be solved using a regular Rubik's cube solving algorithm. This puzzle has only one parity case.

This puzzle has many moving parts thus allowing a huge number of possible permutations. The number of possible permutations of the 5x5x5 Cube is just under 2.83x10⁷⁴. The Current world record for solving it is 34.92 seconds, and it was set by Max Park from the USA at the Houston Winter 2020 competition.

CLEBER

Such an awesome cube!

mini fantastic cuber man

I could solve 3x3 4x4 5x5 and ect all because of grubiks

luis chaparro

Now, I can solve the 2x2-7x7, and the 9x9 lol

Irving de Noronha

This is the MOST OPTIMIZED SOLVER EVERRRRRRRRRRRRRRR

Rubik speed

That’s is a really hard rubik. But finally I can solve it under 20 minutes

Master cuber

I have one and i can solve it, the biggest one i have is 11x11

It was a nice challenge, I have done a 4x4 before but I don't have my own 5x5, I ran into an unfamiliar case along the way and also messed up an algorithm but I was still able to do it with my knowledge of the 4x4. You should still look up a tutorial specifically for the 5x5 though.
