HOW TO PLAY CATHEDRAL

• The object of the game is to place all your buildings within the walls of the city, while trying to prevent your opponent from doing so.
• If you completely enclose a part of the city with your buildings alone or with your buildings and the wall, this part of the city becomes your property and your opponent may not place any of his buildings within it. The buildings must meet wall to wall; a corner to corner contact is not acceptable.
  • You may not use the Cathedral as part of the boundary to enclose the claimed space.
  • Neither you nor your opponent may claim space on your first move.
  • If you enclose and therefore isolate one and only one of your opponent's buildings or the Cathedral you may remove it and claim the space enclosed. The building must be removed immediately after the move during which it was enclosed otherwise it must remain where it is and the space is still available to your opponent.
  • Your opponent's building may be replayed in a later move but the Cathedral once removed is not replaced for the remainder of that game.
  • If you enclose two or more buildings, one of which may be the Cathedral, then none of the buildings may be removed and the space is still available to your opponent.
• The game ends when no further moves can be made by either player. The winner is the player who succeeds in placing all his buildings within the city while preventing his opponent from doing so. If neither player succeeds in doing this then the player whose unplaced buildings would occupy the least number of squares is the winner otherwise the result is a draw.
• When a series of games is played, the players alternate placing the Cathedral and making the first move. At the end of each game players are awarded points equal to the number of squares their unplaced buildings would cover. The winner of the series is the player with the smallest total of points.
