For example, Property 72 is on Neighborhood 7. Property 23 is on Neighborhood 2. Each player is dealt 5 property cards, one each from the first 5 piles. The Neighborhood 1 tile is placed on the table, and players take turns placing another Neighborhood tile on the table contiguous with an existing tile. Strategy is to lay a tile in a way advantageous to you based on the cards you hold in your hand.
Adjacent properties allow the placement of double and triple buildings.
The building is placed on 1 or more of the properties cards you discard from your hand. Proximity to City Hall and streetcars can double or even triple points scored, factories devalue residences and businesses built next to them. Proximity to parks can add a 1 point bonus to residences and businesses. Thus, they can obstruct opponents by covering their properties. Properties covered by these cannot be built on, but players holding these now-useless property cards can exchange them for new ones.
