You own an empty lot with a lobby and some starting cash. Grow it into a thriving tower.
- Build floors on top: apartments bring residents, offices bring workers, shops serve both.
- Add an elevator before going above the first floor. Each car serves 5 floors; overcrowded cars upset tenants. Tap a shaft to add cars (up to 4 share its calls) and see its average wait. A person-count badge marks crowded landings and turns red when people there are getting stressed.
- At 2★, build an Express shaft: it runs much faster but stops only at the lobby and the sky-lobby floors you mark (every 5th floor). People change to a local car there when that gets them home sooner.
- Every day you collect rent and pay upkeep. Happy tenants move in, unhappy ones leave.
- At 2★, add Hotel Rooms (single or twin). Guests arrive 17:00–21:00, ride up, sleep and pay at checkout 07:00–10:00. A Housekeeping Closet cleans rooms after checkout, and dirty rooms can't be booked. Long elevator waits earn a ☹ bad review that cuts bookings for a few days.
- Open a Café (from the start) or a Boutique Shop (at 2★). Instead of rent they earn from every visitor who comes in off the street, so put them where the trip up is quick: shops on hard-to-reach floors get few visitors. Tap one to see today's visitors, income and satisfaction.
- As the tower grows, fires can break out in occupied units. At 3★, build a Security Office: its guards cover the floors within 5 of it and run to a fire by the stairs to put it out. Uncovered fires burn slowly, spread to the next unit and do more damage. Elevators skip floors on fire, and burned units earn nothing until you pay for a repair (tap them). Tap the flame in the top bar to find a fire, or turn Disasters off under Game.
- From 3★, burglars walk in at the lobby now and then, ride the elevators and pick the lock of an empty unit, or of one no Security Office covers. An idle guard from the nearest office rides the elevators there: in time, the burglar is caught and the tower's reputation rises; too late, the thief gets away with cash, the tenant is shaken and reputation drops. The Security strip in the side panel counts caught and missed thefts.
- Dig basements B1–B3 below the street (deeper costs more) and, at 2★, add Parking Garages there. Tap a shaft to take it down into the basements. Office workers drive in, park, and ride up; offices and hotel rooms nearby get a parking bonus, but a full garage or one no elevator reaches stresses tenants. 4★ needs at least one garage.
- Mind tenant stress: people kept waiting turn yellow, then red. Each unit has a green, yellow or red light; tap it for details. A unit left in the red moves out.
- Earn Tower Rating stars (1–5★): reach each star's population and meet its goal to unlock new rooms. Tap the stars in the top bar to see the next goal.
- Watch the Tower health grade (A–F). Stay in debt for 3 days and the tower goes bankrupt.
- Scroll, drag or swipe the tower view to pan up and down. Hover or tap a floor to inspect it.
- Sound starts with your first tap or key press. The speaker at the right of the top bar (or the M key) mutes the music and effects.
- Your tower saves itself as you play; Continue on this screen picks it up again. Export save and Import save keep a backup file.
