To win the game, you must earn the most amount of green cards. The judge chooses the best suggestion, and that player earns a green card and gets to judge next. To play, the judge flips over the top green card, and the other players must put down a red card that best fits with the green one in play.
The deck is divided into red cards (which list people, places, things, and events) and green ones (which have adjectives). Winning is subjective to the judge's preferences
