A regular, traditional Rubik’s Cube is 3x3 by 6 sides.
That’s a total of 54 moving squares to order by color on each side.
This Rubik’s Cube On Speed is 7x7 by 6 sides.
So this cube has 294 squares to figure out.
(I did find another cube on eBay that was even larger, 15x15, called “Professional Level” selling for $384.40)
I’m sure there are some real whiz kids out there that can do these puzzles.
And probably in under 3 minutes…
For me, I admire the dexterity and spatial skills. ;-)
