Beginner method overview


This method is almost the same as Mc Farren method. I have used this method to solve my Cube21® for the first time.

Step 0: Notations
This is a description of the notation used for square-1® algorithms
Step 1: Back to square form (1 algo)
This is an intuitive step to get back the puzzle to a square form
Step 2: Fix middle layer (1 algo)
If middle layer is not square, we fix it. Following steps will not modify middle layer
Step 3: Bring the corners in their correct layer (2 algos)
Bring orange corners on top layer and yellow ones on bottom layer
Step 4: Permute top corners within top layer (1 algo)
Permute top corners to have matching side color
Step 5: Permute bottom corners within bottom layer (1 algo)
Permute bottom corners to have matching side color
Step 6: Bring the edges to their correct layer (2 algos)
Bring orange edges on top layer and yellow ones on bottom layer
Step 7: Permute top edges within top layer (1 algo)
Permute top edges to complete top layer
Step 8: Fix parity problem (1 algo)
When you use this kind of method, you have fifty percent chance to have a parity problem, an algorithm and some diagrams are given to detect this kind of problem
Step 9: Permute bottom edges within bottom layer (1 algo)
Once the parity has been fixed, we can permute edges using a single and simple algorithm

Top/bottom layer views have been generated using php script ImageSquare1 and ImageSquare1s
