@carlton this helps I think: look at the center piece on each side, that defines the color of that side since you cannot move the center piece.

Then try to get one side complete, taking care to not only get the right color on that side but also on the adjacent side. E.g. if you try to get a complete white side, then there is a piece that is white and green, then you know exactly where that piece should be because you know which side is the green side.
