So I looked into this a little bit, what's odd is my cube can be scrambled and solved unlike cubes that were assembled or reassembled incorrectly, so they always get this situation. My cube is a standard moyu speed cube, the corners and edges cannot be flipped without breaking them off, I have not had to reassemble it yet. The cube has been manufactured correctly. enter image description here I only got this situation because I used basic algorithms. What's an algorithm for when 2 opposite top edges need to be swapped to solve?

  • I don't think this is possible??? I think you did something weird. – greenturtle3141 Apr 03 '18 at 18:44
  • I've seen people say that you can get this with basic algorithms. – Bryce Apr 03 '18 at 18:46
  • Both those people have somethong wrong with their cube where they can't solve it. I can scramble and solve it. EDIT: Though I did use that picture because it describes my situation. Yet all of the algorithms on that post just reset the lat layer. I want to know how to solve it from this state. – Bryce Apr 03 '18 at 18:49
  • It cannot be solved with normal moves only. If you cannot disassemble the edges/corners, what you could do to make it solvable is to rearrange the caps of the centres. – Jaap Scherphuis Apr 03 '18 at 18:52

    I can solve it using normal moves, I've been solving it for the last 40 minutes now. I just needed reset the last layer with something like R U R' U R U2 R'. I just want to know how to solve it from this state, not by reseting layers. – Bryce Apr 03 '18 at 18:53
  • You have something wrong with your cube, just like those other two duplicate posts. It is mathematically impossible to swap two pieces in isolation using normal moves only, because every move is equivalent to an even number of swaps and can never be the same as an odd number of swaps. The only way to return your cube to a normal solved state is to disassemble it (possibly just the centre caps). – Jaap Scherphuis Apr 03 '18 at 18:58
  • It's currently in a solved state. Normally I care about theoretical mathematics, but this was a situation I got yesterday. EDIT: One weird thing with it is that I got this when I put the last edge in place. – Bryce Apr 03 '18 at 19:02
  • Then you are mistaken. There must have been other pieces that were unsolved in addition to the two edge pieces. (EDIT: or you mistook two flipped edge pieces for an edge swap) – Jaap Scherphuis Apr 03 '18 at 19:02
  • It's possible, I can't really remember things, and I can't be 100% sure. Thanks – Bryce Apr 03 '18 at 19:14
  • Happened me once. Had ti give it to my girl to scrumble enough to get back to normale state. However I would Like ti obtain an algorithm for that. – CoffeDeveloper May 06 '18 at 16:17
