The game consists of two Acts, with players taking turns in clockwise order. Players win by defeating the Boss in Act 2, or lose if one of these three situations occurs:
1. A fifth Goblin must be placed but four Goblins are already in the dungeon.
2. The torch reaches the skull () at the end of its track.
3. The dungeon cannot be explored any further (no open corridors) and the Lair Door Card has not been revealed.
