Dandy (later Dandy Dungeon) is a dungeon crawl maze game for the Atari 8-bit family published by the Atari Program Exchange in 1983. It is one of the first video games with four-player, simultaneous cooperative play. Players equipped with bows and unlimited arrows fight through a maze containing monsters, monster spawners, keys, locked doors, food, and bombs in search of the exit leading to the next level. If a player dies, they can be revived by finding and shooting a heart. The game includes an editor for making new dungeons.
