Rockets Puzzle

Use your mouse to drag the colored button images.

In the rocket assembly station, eight new rockets are nearing completion. Due to specialized construction equipment in various sections, the rockets have to exchange their places. Rockets A, B, C and D must fit into areas 9, 10, 11 and 12, respectively.

During the moving, only one rocket can fit into a section at any one time. Nothing is in areas 5, 6, 7 and 8, so they can be used for juggling. When moving, you can go as many spaces at a time as wanted, if they are available. The puzzle is solvable in 43 moves, but it isn't guaranteed to be any easy puzzle to solve.
