About Coaster Kingdom

Coaster Kingdom is a free theme park tycoon in your browser, in the spirit of RollerCoaster Tycoon. Lay paths, build rides and stalls, design roller coasters piece by piece, hire staff, set prices and keep the crowds happy.

The park is in 3D, and you can ride any coaster you build from the front seat. Guests have their own cash, hunger, thirst and nerve, and they tell you what they think. It's an Etheria original for all ages, with no loot boxes and no real brands.
