Cosmic Contraband is a social bluffing game where you take on the roles of Smuggler and Justicar to lie your way into getting credits, whilst accusing your friends of doing just that. As a Smuggler it's your job to transport as much cargo (good or bad) past the Justicar as possible- as long as you promise it's legal. As the Justicar you have one job- not to find out who's lying, but to find out who's lying the most and 'confiscate' any contraband for 'safe keeping' - AKA keeping the credits for yourself. The player with the most credits at the end of the game wins and is the best liar... probably.
