Re: Ah good old school days..
I'm in the same boat as Martin, more than 30 years ago the "algorithms" was learded, some self taught, some shared, were imprinted into my mind. I can still do the cube without really thinking about it, I do need to look at it several times though.. unlike the guy doing the 20 cubes ... whilst blindfolded....
Always the same method.
Top Face - No importance as to whether the corners or middle are inserted first. This is the easist section - very little, if any, thought required.
Algorithm reverses dependant on the original orientation of the piece to be inserted ( to the left or to the right ). Only one algorithm required.
Bottom row - -
One algorithm for swapping 3 middle pieces at a time. ( all pieces rotate to the left or right as required)
One algorithm for inverting middle pieces if upside down.
One algorithm for swapping 2 corner piece positions until all pieces in correct positions..
Last and final algorithm for inverting all corner pieces to their correct orientation, the positions dont shift .
