First solve the three yellow tri-color corners so they are in the positions shown, then move them so they are all in the front layer as shown by pressing play. The orientation of the centers can be ignored, they are solved last (they don't have to match the cubes on these pages).

If the remaining tri-color corner (red-green-blue = RGB) is in the back layer then twist it until it is in the position shown below (up-back-right). If it is in the front layer then do moves D B D' to move it to the back layer. In either case the result will match one of the cubes below (the only difference is the orientation of the RGB corner). The move sequence on each cube shows how to solve the tri-color corners by moving the RGB corner to its proper position while restoring the other two to the solved state.

As an alternative, the RGB corner can be solved directly from whatever position/orientation that it happens to be in after solving the three yellow tri-color corners although that requires 14 sequences to cover all of the possibilities, those can be found here.

After the tri-color corners are solved, the four remaining single-color corners can be solved using the method shown here. However, the opposite face arrangements look completely different, the following shows how to recognize them with the first two being solvable with half-twists and the second two not.

After the tri-color corners are solved there are only 24 possible configurations of the single-color corners. A listing of those configs with solutions is here.
