New and NEVER Ending Tunnels

This cast Brain Teaser cinsists of two metal pieces joined together. 

Imagine the captol letter C.

The first is round like a coin and has a series of tunes mazes on both sides. 

The second piece hooks around and latches onto the main unit. 

The puzzler must simultaneously navigate the top and bottom maze,

 by sliding the second piece through the labyrinth and around to the exit point. 

You get 1 hint, moves that work for one side of the maze might not work for the other!
