In Adventure, the player controls a square avatar across thirty rooms containing castles and mazes. An evil magician has hidden the Enchanted Chalice somewhere in the kingdom; the objective is to retrieve it and bring it back to the Golden Castle.
Items scattered around the world help with exploration. Keys unlock the three castles, a magic bridge lets the avatar pass through barriers, and a magnet draws other items toward it. Three roaming dragons can swallow the avatar, trapping it inside their bellies. A bat also moves items around the kingdom, stealing them and hiding them elsewhere.
