Space Pinball is the name given to the prototype that would eventually become Galactic Pinball. Space Pinball was near complete before it was scrapped. It features 5 tables, where Galactic Pinball only has 4. All 5 of the prototype pinball tables are different from those that were included in the retail game.

In the prototype, all tables are linked together. Beating a table just starts you off at the next table, and there is no ending of any kind. There is also no “puck” counter, the game simply returns to the stage select screen when you lose a “puck”.
