The Game is a non-stop 24- to 48-hour treasure hunt, puzzlehunt or road rally that has run in the San Francisco Bay and Seattle areas. Its teams use vans rigged with power and Internet access and drive hundreds of miles from puzzle site to puzzle site, overcoming often outrageous physical and mental challenges along the way, usually with no sleep. Teams in games have been required to walk around the roof of the Space Needle, find a puzzle hidden in a live rat, and circulate a petition to ban dihydrogen monoxide from local ecosystems while dressed in superhero outfits.

A puzzle hunt is an event where teams compete to solve a series of puzzles, many of which are tied together via metapuzzles. Puzzlehunt puzzles are usually not accompanied by direct instructions for how to solve them; figuring out the necessary approach is part of the puzzle. These hunts may be hosted at a particular location, in multiple locations, or via the internet.
