Saratoga

'Saratoga' was the first machine to feature an active bumper of the type that used a metal ring to repel the ball, identified in the manufacturer's flyer as a thumper bumper. This style of active bumper would soon replace the ones using a compressed spring to repel the ball, found in other games at the time. The earliest spring compression bumpers were found on Stoner's 1938 'Super-Zeta' and Stoner's 1938 'Zipper'. The upper playfield has two stationary bumpers that look like flippers.
