Handheld Marble Run Maze - Can you find your way out of the maze, or will you be lost forever?

Challenge your friends, mesmerize small children and pets, guaranteed hours...er, minutes of fun!

Edit - In case the original model was too challenging, I've added a model that keeps the marble in a tunnel within the maze. You can even try solving the maze upside-down!

FYI, my cats were able to solve it, if you consider hitting it a few times and then walking away solving it that is!

(Designed for 10mm or smaller marbles - Warning: Small parts - Choking Hazard!))
