Magic Cube - Build Your Own Formula


This is NOT for speed up. try to build & understand the formula

there are many methods to solve the cube.
layer by layer / cross,F2L,OLL,PLL / corners first / edges first / columns first / 8355 / ...
these methods can solve the cube, but you have to learn the formulas. but most formulas not easy to understand.
e.g. the common method cross,F2L,OLL,PLL. cross & F2L formulas are easy,
and many people can solve the first 2 layers without formulas.
but OLL & PLL not easy to understand, and I forget after few months.

I have find for a long time & found this method (but I lost the bookmark) & forget some formulas
but I remember the conept & try to rebuild the formulas.


Basic Move:
X: L M R
Y: U E D
Z: F S B

Method:
step 1: try to made some change on one side, e.g. exchange two edge on side U with S M D' M' D2 S'
step 2: try to change that side, e.g. U
step 3: reverse step 1, S D2 M D M' S'
step 4: reverse step 2, U'
vs
S M D' M' D2 S'S D2 M D M' S'
Demo Demo


Concept:
Any change can be undo with the reverse moves. e.g. S M D' M' D2 S' -> S D2 M D M' S' / L R U D F B -> B' F' D' U' R' L'
Without step 2 & 4, step 3 will undo ALL change from step 1
step 2 change one side, then step 3 will undo other sides change
on that side, if step 1 exchange two corners, then step 3 will exchange another two corners

try & find the formulas:

First, on the same side:

change the side U & use other sides as working area

exchange two edges on side U:
move: disconnect & connect

above formulas can solve 2x2x2 & 3x3x3 cube

these just some basic formulas, try to find more...



above formulas change one side only.
try made some adjustment before & use the reverse moves after the formula to undo the adjustment
the adjustment may made the formula more flexible

Method:
step 0: try to made some change, e.g. R D
step 1: try to made some change on one side
step 2: try to change that side
step 3: reverse step 1
