Subdivision mimics the city-building feel of Bézier Games Suburbia, but differs in scope as now each player has been allocated a specific area in which to create the best possible subdivision, filling it with residential, commercial, industrial, civic, and luxury zones, while balancing various improvements to the area, including roads, schools, parks, sidewalks, and lakes. By the end of the game, each player will have created a unique, custom neighborhood with areas that interact with each other, hoping to outscore the competition by having the best subdivision.

In the game, each player starts with a subdivision player board and a hand of hex-shaped zone tiles. A parcel die is rolled to indicate the type of parcel where a zone tile may be placed, and all players simultaneously place one of their tiles. If a zone tile is placed next to existing zone tiles, those existing tiles have the ability to create new improvements, which may also be placed at this time. Those improvements provide money and points, while slowly covering up as many parcels as possible. Players pass the remaining zone tiles in hand to their left, then someone rolls the parcel die once again. This continues until only one zone tile remains in hand, which is discarded.
