Role-playing board games like Dungeons & Dragons are known for their overly complicated multi-sided die. But this particular set turns the dice into the actual dungeon, letting players discover a new random challenge every time they roll.
All 30 sides of the five die have different dungeon layouts with entry and exit points that let them all connect into a larger layout when combined. The $20 is perfect for mini-quests when you're away from your home board, but don't forget your numbered tetrahedral die or your love of make-believe danger. [ThinkGeek]
