Marble Madness is an arcade video game designed by Mark Cerny and published by Atari Games in 1984. The game involves guiding a marble through six levels filled with obstacles, ramps, and challenging terrain with the goal of reaching the finish line before time runs out. It is known for its innovative use of isometric graphics and its early use of true physics in gameplay. The version for the Game Gear, a handheld system by Sega, allowed players to experience the addictive gameplay on the go. This adaptation maintained much of the original arcade's design and gameplay, albeit with adjustments made for the handheld's capabilities.
