Each one of these plastic mazes is named for a great thinker (Galileo, Tesla, Copernicus and Newton), reflecting the huge amount of brain power it takes to solve them. Can you steer the ball through the mazes without becoming confused and distracted by the eye-straining optical illusions? Or will the stress and strain make your brain explode! Four 2-1/4" to 2-1/2" wide mazes.
