They've been split up from their friends in the black and white maze.
Use the five panels to connect the maze paths so that the white ghosts are reunited with each other and the black ghosts are reunited with each other too.
Slide the panels to move them and complete the maze in the right-hand frame.
The panels that are already placed cannot be moved.
The white ghosts take the black path and the black gosts take the white path.
Connect the black paths so that the white ghosts at the top-left and centre can go around the area where the top-right black ghost is located.
Connect the white paths so that the black ghosts at the bottom-left and top-right can go around the area where the top-left white ghost is located, in an N-shaped path.
Looking at the five panels lined up on the left of the maze, the one at the top needs to go on the left side of the maze.
The panel below that goes at the bottom-right of the maze, and neither of them need to be rotated.
Continuing on from hint three...
The bottom-left of the five panels goes on the right side of the maze, and the remaining panel on the left goes at the top.
Both of them need to be moved into the correct position.
You're nearly there now.
