San Juan is a strategic card game for 2 to 4 players. It's often referred to as "the little brother" of the boardgame Puerto Rico which can be played on BSW as well. The players let the city of San Juan grow by erecting city and production buildings. The build of a hand card is paid with other hand cards. Each building provides victory points. Most of them have special functions bringing advantages for the owner in the further game. Every turn, the players chose roles like Mayor or Builder taking advantage of the role-related privilege. Once a player has built his 12th building, the game ends after this round.
