Time has shattered, and you have to put it back the way it was — or at least close enough to how it was to fool your opponents. Bluff your way through history! ChronoSphere is a bluffing and historical trivia card game. Players play their cards into a shared circular timeline called the ChronoSphere. Players try to arrange the events and inventions shown on their cards in chronological order, using one half of the ChronoSphere for cards from the time period AD and the other for the time period BC. The first player to successfully play all of their cards is the winner. Players can challenge the plays of their opponents and force them to draw cards for invalid plays. A player can also win by completing a fully valid twelve-card ChronoSphere.
