"Skylab" and "Spacelab" are two pinball machines produced by Williams in 1974. "Skylab" is the replay version, while "Spacelab" is the add-a-ball variant. Both machines share a space exploration theme, with artwork that features astronauts and celestial elements, reflecting the fascination with space missions during that era.
Skylab
Quickie Version:
UTAD, via banking the ball off any SKYLAB letters you need.
Go-to Flipper:
Balanced
Risk Index:
Very High
Full Rules:
There’s not much here to shoot - - the captive ball and UTAD via the S-K-Y-L-A-B letters are about it, and the latter is the less drainy of the two choices. Each time you complete Skylab you get two bonus advances; each lit lane at the top and the return lanes give you one advance. The little red rollover buttons labeled “change” alternate which lanes are lit for an advance. Bonus maxes at 24K and is doubled on the last ball. Ignore the captive balls unless the Special award is active and good for either an extra ball or significant points - - check the instruction card or watch other players to see. If it’s on, getting all 5 balls to the lit side scores it. If not, even after maxing out your bonus, UTAD is still safer than shooting the captive ball.
