Setup:
Choose a random Beach card to add to your 3 scoring conditions and shuffle the others into the deck with the blocks side face-up.
How To Play:
When you draw a Beach card, you must play it immediately. Each Beach will create a new border that you cannot cross with other cards (imagine that the beach continues beyond the edge of the card).
During the game, you must define 3 out of 4 borders (north, south, east, west) and continue to build your city within those edges.
The Beach scoring card may provide extra points to offset the new challenges.
