One bottle per person is the new law — thus bribes, suitcase inspections, and arrests are on the agenda.

Each round, one player takes a turn in the role of a border guard while the other players act as travelers. In a quest to acquire coveted carbonation and its accompanying bottle caps, the border guard tries to confiscate as many sodas as possible while only the cleverest travelers will sneak across with their fizzy contraband. After each player has been the border guard (twice in a 3-4 player game, once in a 5-8 player game), the game ends and whoever has the most bottle caps wins!
