core loop

build floors, lobbies, and elevators -> place offices, condos, hotels, and shops -> tenants travel by elevator on daily routines -> long waits raise stress and drive tenants out -> rent and population raise the star rating -> unlock new facilities

design notes

SimTower turns a building into a vertical transit problem: standard elevators span up to 30 floors and express elevators the full height, so the player designs shafts, sky lobbies, and stops to keep queues short as the tower grows toward 100 floors above ground and 9 below. Tenant stress, not money alone, gates the star rating from one to five and finally the Tower rating, which needs a cathedral on top. Events such as a terrorist bomb ransom, VIP visits that can unlock a star, fires, and pests interrupt the routine.

uses

Daily schedules

Office workers, residents, shoppers, and hotel guests travel at different times of day, creating rush periods at lobbies.

core
uses

Building placement

Floors and tenant units are placed on a side-view grid; tenant type and position set elevator demand.

core
uses

Milestone unlocks

Population and conditions advance the tower from one to five stars and then to Tower status, each step unlocking facility types.

core
uses

Service queues

Tenants wait at elevator lobbies; long waits raise stress, and stressed tenants move out.

core
uses

Agent pathfinding

People route between floors by elevators, escalators, and stairs.
