SimCoaster takes the operation of an amusement park, introduced in games such as Bullfrog's 1994 Theme Park and 1999's SimTheme Park, and focuses on the roller coaster as the main attraction. Successful overall management of the theme park requires efficiency in ride designs, layout, finances, facilities, public relations, human resources, monitoring customer happiness, and researching technological advances. Players can, however, ignore the micro-management aspects of every day operations and concentrate entirely on researching, building, testing, and riding roller coasters.

For gamers interested in managing a simulated theme park, specific tasks are offered in a mission-style format. By successfully completing tasks, players earn stock in the company and eventually become the successor to the retiring park president. Efficiency in hiring and firing staff (janitors, engineers, entertainers, guards, gardeners, and scientists), building attractions and rides, providing comfort and necessary amenities for customers, and ensuring visitor contentment all play a part in SimCoaster.

The game features more than 100 rides and sideshows, 18 roller coaster styles, and three distinctive themes (Land of Invention, Polar Zone, and Arabian Nights). In addition to pre-built coasters for use in the park, a Coaster Design Kit allows the development of roller coasters and flumes after researching them within the game. Creations can be shared with other coaster enthusiasts via e-mail or on the Internet. ~ Michael L. House, All Game Guide
