Solution: Move the right-center tile to the center. Now move the top-right
downwards. Take the top-center to the right and the center tile needs to go up.
Next the left-center needs to be moved to the center and the bottom-left will
move up. Now move the bottom-center to the left and the right-center down. Take
the center tile and move it right. The top-center will need to go down while
the top-left needs to go right. Take the left-center up and bottom-left up.
Now move the center down and right-center to the center. The bottom-right can
be moved up. Insert the tile you picked up earlier.
