In slightly more detail, to set up the game, lay out a ring of town figures at random, with two of them being removed from play each game. Whoever is farther behind in the circle around town takes the next turn, advancing to whichever town figure they want to visit. Most of them give you resources — brick, steel, or money — and you have a limit on how many resources of each type you can hold. Some figures have two random building plans at them, and if you visit one with the right resources, you can pay them, then build something. If you pay extra, you can then build something else, too!
The first building is placed anywhere in the midst of play, then each subsequent building is placed adjacent to something already built, with the buildings eventually filling in a 4x4 grid of the players' own creation. As soon as the sixteenth building is erected, the game ends and players score points for what they built. Who has contributed more to the current state of Glasgow?
