Marble Madness is a 1984 platform game designed by Mark Cerny and published by Atari Games Inc. for arcades. Set in an isometric perspective, the game tasks the player with guiding a marble through six courses, populated with obstacles and enemies, within a time limit. The player controls the marble by using a trackball. Marble Madness is known for using innovative game technologies: it was Atari's first to use the Atari System 1 hardware, the first to be programmed in the C programming language, and one of the first to use true stereo sound.
