Marble Madness is an arcade video game designed by Mark Cerny and published by Atari Games in 1984. It is a platform game in which the player must guide 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.
