Rubiks Cube 4x4
Are you ready for a new twist on the Rubik’s Cube? But beware! Rubik’s Cube is extremely addictive and may drive you crazy. You think you’ve nearly solved it, but then you make a turn on the cube and it changes all over again.
Also known as “Rubik’s Revenge” or the Master Cube, it’s not more difficult than the original 3x3x3 cube, but it does require different techniques to solve it.
The world record single fastest time is 24.33 seconds set by Sebastian Weyer of Germany at Velbert Easter Open 2014. Oliver Frost of the United Kingdom holds the world record for solving the 4x4x4 cube blindfolded, in 2 minutes, 30.47 seconds, set at the Oxford Open in 2014.
And just in case you were wondering, there are 7.40 x 1045 different ways of arranging the 4x4x4 cube – the full number is:
7 401 196 841 564 901 869 874 093 974 498 574 336 000 000 000 possible permutations
