The 5x5 speed cube, originally named as the Professor's Cube, was invented by Udo Krell in 1981! It was later manufactured and sold by Uwe Mèffert in 1983.
It consists of 5 layers and 98 cubic pieces, and it is solved using several variations of the reduction method. It is a very popular WCA nxn puzzle because it's the middle ground between big and small cubes.
A few years ago, 5x5 cubes had lots of lockup problems. All of this changed when the Wushuang 5x5 was released. It had 45° degree corner cutting, high speed and good stability! Many speedcubers got interested in the event after this product was released.
During World Championships 2017, Feliks Zemdegs became the first cuber to solve a 5x5 cube in under 40 seconds using the same cube!
Why 5x5 Speed Cubes?
5x5 speed cubes are a great addition to every cube collection! They can be used to get better at edge pairing for big cubes and for training your finger tricks and look ahead.
When a cuber solves a 5x5 cube, his/ her problem solving and analytical skills are put to test. This improves the cuber's cognitive skills.
Solving different cases and color combinations also help to improve the concentration of a cuber.
5x5 speed cubes are really fun to solve and every cuber should pick one up!
