You take care of any bad edges in the third layer with move 5, which shifts the front edge to the back side, the back edge to the right, and the right edge to the front. If the front edge needs to go to the right instead, do the move twice or, better yet, reverse both of the U turns.
The setup is simple. If one side is solved, turn your cube so the solved side is on the left.
Case 1: If all edges are bad, do move 5 once with any face forward. YouŽll end up with one good edge.
Case 2: If the front edge belongs on the back when the solved edge is on the left, do move 5.
Case 3: If the front edge belongs on the right when the solved edge is on the left, reverse the Up turns when you do move 5, or, if you can't get enough, to move 5 once to get case 2.
When all 4 edges are good, you're done! Click here to increment the counter.
