Playing Boss Monster requires you to juggle two competing priorities: the need to attract heroes at a faster rate than your opponents, and the need to kill these heroes before they reach your boss. Players can build one piece per turn, each with their own damage and treasure value. More attractive pieces tend to deal less damage, so an overly greedy boss can be inundated with deadly heroes.

Players interact with each other by building chambers and playing spells. Because different heroes are looking for different types of treasures, and the rooms are built simultaneously (played face down, then revealed), this means that each "construction phase" is a bidding war. Spells are instantaneous speed effects that can give players advantages or confuse opponents.

As a standalone card game with 155 cards, Boss Monster contains everything 2-4 players need to play.
