What Is SimTower?

SimTower is a construction and management simulation developed by OPeNBooK and published by Maxis in 1994 for MS-DOS, Windows, and Mac. It puts you in charge of building a single skyscraper, starting from a lobby and a few elevators and growing it into a sprawling vertical city of offices, apartments, hotels, shops, restaurants, and more. Your goal is to keep tenants and visitors happy enough to earn a higher star rating, eventually unlocking the prestigious TOWER status.

SimTower is celebrated for its unique vertical twist on the simulation genre and its surprisingly deep elevator logistics — moving people efficiently up and down your tower is the central puzzle. Balancing construction costs, tenant satisfaction, and the constant flow of foot traffic gives it a compelling, almost meditative pull. Part of the SimCity-era Maxis lineup, it became a cult favorite that fans still enjoy decades later.

How the Game Works / Gameplay Basics

You build your tower one facility at a time, placing offices, condos, hotel rooms, shops, restaurants, and services on different floors. Each facility type has its own needs and income, and tenants will only stay if they're satisfied — which depends heavily on how easily they can get around. That makes elevators and stairs the heart of the game: you must design transit that moves crowds quickly, especially during morning and evening rush hours.

Your tower earns a star rating that rises as you grow and keep tenants happy, unlocking new facility types like cinemas, parking, and eventually a cathedral at the top. You'll manage rent income, construction costs, and problems like overcrowded elevators, while keeping an eye on tenant happiness (shown by the color of their tiles). The challenge is balancing ambitious expansion against the logistics of keeping thousands of simulated people moving smoothly — all the way to the coveted TOWER rating.

Beginner Tips

• Prioritize elevators. Efficient transit is the key to happy tenants — avoid long waits.
• Watch tenant colors. Red tiles mean unhappy tenants; investigate and fix the cause.
• Stagger your facilities. Mix offices, homes, and shops to spread out foot traffic.
• Add express elevators. As your tower grows tall, express lifts cut down travel time.
• Grow steadily. Expand as income allows rather than overbuilding and going broke.
• Place services smartly. Restaurants and shops near offices and hotels boost satisfaction.
