The labyrinth can be reached by using the magnetic crane or the cannon. The ball bounces among the pins and falls into one of the three wire bins at the bottom. The ball always seems to fall into the left or center bin, but you can sometimes light the third bin by shaking the iPod as the ball drops.
During the tank mission, the labyrinth goes from pins to levers and results in a 3-ball multiball.The labyrinth is on top of Leonardo da Vinci's design for an armored tank. The tank had a shallow cone over a cart with cannons sticking out the sides and operated by men underneath.
