Restore Cubic Shape
Restore the puzzle to a cubic shape.
Case 1
All 8 edges next to each other.
/ 2,4 / 1,2 / -3,-3 /
Case 2
7 edges next to each other.
/ -2,0 / 3,-4 / -2,0 / 3,0 / 2,4 / 1,2 / -3,-3 /
Case 3
6 edges next to each other.
/ 0,2 / 4,0 / 2,4 / 1,2 / -3,-3 /
Case 4
5 edges next to each other.
/ -2,0 / 2,0 / -2,0 / 3,-4 / -2,0 / 3,0 / 2,4 / 1,2 / -3,-3 /
Case 5
4 edges next to each other.
/ 2,2 / 1,2 / -3,-3 /
Useful Algorithms
During the next few steps, it may be necessary to perform these algorithms.
Case 1
Swap top layer with bottom layer.
/ 6,6 /
Case 2
Restore middle layer to square shape.
/ 6,0 / 6,0 /
Corner Orientation
Move corners onto their correct faces.
Case 1
Swap corner from top layer with bottom layer.
1,0 / 0,3 / -1,0
Case 2
Swap two adjacent corners from top layer with bottom layer.
1,0 / -1,0
Case 3
Swap two diagonal corners from top layer with bottom layer.
1,0 / 3,3 / -1,0
Edge Orientation
Move edges onto their correct faces.
Case 1
Swap right facing edge on top layer with back facing edge on bottom layer. Repeat for other swapped corners.
1,0 / 3,0 / 3,0 / -1,-1 / -2,1 / -3,0 /
Case 2
Swap opposite edges on top with opposite edges on bottom.
1,0 / -1,-1 / 0,1
Corner Permutation
Swap corners into their right position.
Case 1
Swap two corners on the front of the down layer. Repeat for other swapped corners.
/ 3,-3 / 0,3 / -3,0 / 3,0 / -3,0 /
Edge Permutation
Swap edges into their right position.
Case 1
Swap back facing edge with right facing edge on both layers. Repeat for other swapped corners.
-2,0 / 3,0 / -1,-1 / -2,1 / 2,0
Edge Parity
Cycle edges so that three edges are incorrect instead of just two. Then repeat the previous step.
Case 1
Only two swapped edges remain. Perfom algorithm, to cycle top layer edges, then repeat the previous step until solved.
/ 3,3 / 1,0 / -2,-2 / 2,0 / 2,2 / -1,0 / -3,-3 / 0,2 / -2,-2 / 2,0
