Snake Rattle 'n' Roll is a platforming video game developed by Rare. It was published by Nintendo and released for the Nintendo Entertainment System in North America in July 1990 and in Europe on March 27, 1991. It was ported to the Mega Drive and released by Sega in June 1993. The game features two snakes, Rattle and Roll, as they make their way through eleven 3D isometric levels. The object is to navigate the obstacles in each level and eat enough "Nibbley Pibbleys" to ring a weigh-in bell located in the level, which will allow the snakes to exit. The game can be played by a single player or by two players simultaneously.
