A Strategy for Solving the 6-Color Fisher’s Cube
Starting with the silver corners is kind of like starting with the white edges of a cube, except for the added challenge of getting the middle layer edges correct as you go. It is possible to ignore the middle layer edges at first and twist them if necessary later, but it isn’t that hard to get them oriented correctly as you go, so why not.
The silver corners are the pieces with 3 colors on them, one of which is silver. When you put a silver corner next to the silver center do it in such a way that the edge above the corner is oriented correctly.
Getting the edge-center pairs on the Fisher’s Cube is sort of like getting corner-edge pairs when doing the first two layers of a normal cube. It is easier, though, in that unlike the edges of a normal cube, orientation does not matter for the Fisher’s Cube centers. There is only 1 color on the center. This gives some flexibility in pairing up the edge-center pairs that isn’t there when solving a normal cube.
This corresponds to getting the yellow edges of a normal cube. There is an extra challenge here though. It is in the orientation of the corners. In a normal cube after solving the first two layers, either 0, or 2, or 4 yellow edges will be oriented correctly. Never 1 or 3. Well, not unless the cube has been disassembled and reassembled with an edge flipped. But with the Fisher’s Cube it is very likely that you will have 1 or 3 gold corners twisted. In a normal cube you can’t have one flipped edge. Edge flipping must be done in pairs. But in the Fisher’s Cube the 8 corners and 4 middle layer centers all correspond to normal cube edges. So what if when solving the middle layer an odd number of the centers are flipped the opposite way from the way they were before scrambling? They would look solved, but because they weren’t, an odd number of the gold corners would have to be flipped. To deal with this, simply flip any one of the middle layer centers along with one of the gold corners.
The gold edges on the Fisher’s Cube are like the yellow corners on a normal cube, so I use the Up-Replace-Down Corner 3-Cycle Commutator! The challenge is in figuring out the proper orientation of the edges. Since they only have 2 sides, but function as if they have 3, it is a bit tricky.
