Harbour is a worker placement game where players move their worker from building to building, collecting and trading Fish, Livestock, Wood, and Stone; and cashing those resources in to purchase buildings (which are the worker placement spots) from the central pool. Once a building is purchased, it is replaced from the deck, and the central pool is a small subset of the deck, and is therefore different every game.

The game ends when a player has purchased his fourth building. After that round finishes, the player with the most points worth of buildings is the winner!
