From the box: The beautiful stained glass windows of Matthew, Mark, Luke and John need your help. Use all of your cards to rebuild the apostles and you win Church Windows! User summary: Players "rebuild" church windows by swapping cards from their hands to mixed up windows on the table. Once a window is repaired, a new window in the opposite color (red or black) can be built next to the repaired window. The player who gets rid of their cards first is the winner.
