5 x 5 Rubik’s Professor Cube
![]() |
I haven’t ever tried to solve a Rubik’s Cube. I do recognize that it is a classic, and changes to the venerable cube interest me. I am not sure why anybody save the most hardcore cube fans would be interested in upping the difficulty to 5 x 5 x 5. There is also a 4 x 4 x 4 version. The Rubik’s Professor Cube 5 x 5 is on sale at Amazon for $19. |
