Trying to solve the middle layer. Everyone keeps saying there are only 3 possible scenarios: 1)top layer edge needs to move right diagonal 2)top layer edge needs to move left diagonal 3)edge piece in middle layer is correct bug backwards. I have a 4th scenario, though, and don't know how to address it. I've gotten the first two layers solved except for two edge pieces in middle layer. My solved layer is green. The pieces I need to solve: 1)orange/yellow edge piece is on the white/red edge side and the red/white edge piece is on the yellow/orange edge side. I'd attach a picture but I don't understand how to. Sorry. If anyone can help a Newbie--I'd appreciate it.
