Hats is an online party game in which teams compete to guess the most words over the course of three rounds. To start, you and your friends submit phrases to a central pool. These can be as simple as "Socks" or as esoteric as "The End of Summer Vacation." Or like, even crazier. Every game is unique, tailored to whatever kind of mood you're in. When you've entered enough, you pick teams and the games begin.
