Welder's Mask Algorithms
Here you'll find algorithms for all 81 of the Welder's Mask cases. Each of the solutions to the cases is 2-gen, i.e. the only twists used are F moves and R moves. Each case can be solved optimally in at most 6 twists.
This step is supposed to be intuitive. Let these algorithms serve as a tool, not a tutorial.Sorry in advance for any errors. If you find one, please let me know. (This table was made without a skewb in hand.)
How to Find Your Case
Finding your case is easier than it seems. Each case is identified by four characters.
First character
Permutation of the UFR corner
|
Second character
Permutation of the UBR corner
|
Third character
Orientation of the UFR corner
|
Fourth character
Orientation of the UBR corner
|
All in all, the combinations should read like so: AA11, CA23, BB31, etc.
Below, there are nine tables, each with a subset of cases pertaining to piece permutation. The columns 1, 2, and 3 represent the third character, and the rows 1, 2, and 3 represent the fourth character.
