Dungeon Party is an easy-to-learn, raucous, play-anywhere, social role-playing game, where the rooms, monsters, and treasures are all on bar coasters. Players take turns bouncing a coin to "hit" the monsters, disarm traps, or avoid cursed rooms. Players work together to survive the dungeon and gather the most loot, but there can only be one winner!

On their turn, a player reveals a room and monster, battles the monster, and recovers treasure. The game ends if all players’ characters are defeated in an encounter and the adventure failed, or if the last Boss monster has been defeated and the adventure has succeeded and you win.
