Roller Coaster is a 1971 electro-mechanical pinball machine designed by Ed Krynski and produced by Gottlieb. This two-player game is notable for being the first Gottlieb machine to feature metal wireform ramps, known as habitrails, which guide the ball from kick-out holes back to the flippers. These habitrails were a precursor to the more complex ramps seen in later pinball machines.
