Future Spa

Future Spa is a solid state, wide body, pinball machine produced in 1979 by Bally Manufacturing. It was Bally's first machine with continuous background sound and in-line drop targets. Notable game features include: Flippers, Pop bumpers, Slingshot, Spinning targets, Kick-out hole, Star rollover, 4-in-line drop targets, Left kicker lane, Left out-lane detour gate.
It was unique in the fact that it had recessed back-box lighting and prismatic diffuser behind the "Future Spa" logo for a holographic effect. The holographic effect was an idea of Norm Clark. He wanted to do this already on Magic Town / Magic City while working at Williams but it was regarded to be too expensive. The marketing slogan from the Bally flyer read: "Future Spa will awaken your pinball senses"
