Rubik's cube trick?

[MYKE]

i'm looking for somone who knows this!

there is some kind of algorithm that is like a bunch of Rs and Us and the cube gets slightly scrambled and then it is solved again.

does any one know this??

I think if you repeat any combinations of moves for long enough the cube will be solved again.

Any set algorithm, will eventually turn the cube back into its original state.

For example: R U R' U' * 6

Now try R U and see how many repetitions it takes.

BTW: I think rur'u' is one that looks pretty scrambled halfway through, but gets restored with fairly few repetitions anyway.

R U takes a fair few repititions, i just tried :x

 

[aznblur]

63 to be exact.

Actually, (R U') takes 63 repetitions, (R U) takes 105.

A personal favorite of mine (though it isn't R's and U's) is this one:

R y or you could write it R B L F

I find that it actually works pretty well as a pseudo-scrambler. If you do this a bunch of times and then try to solve, it's often almost as if a regular scramble was applied.

Cruel assignment: Figure out how many repetitions THIS takes!

if i recall correctly, it was about 315 repetitions of RBLF. i used to do this to loosen up the cube, go one way til it solves, then go the other. ~600face turns would make a fairly loose cube

my favorite pseudo-scrambler (altho it has very few repetitions, i think like 60) is R U R' f R' U y. it's finger trickable and has very fast effects (after just 2-3 repetitions, it looks pretty scrambled
