RollerCoaster Tycoon 4 Mobile is a defunct 2014 construction and management simulation video game, developed by On5, UAB and published by Atari.

The person playing, the "Tycoon", was able to build and maintain rides such as carousels, bumper cars, roller coasters and a ferris wheel.

Roller coasters could be either custom built or pre-built, made of wood, steel, titanium, or carbon and edited later.

On 9 January 2016, two new coasters, hanging and bobsled, were added along with the option to create new parks and build a big empire.

Chris Schilling for Eurogamer also criticised the music, calling it "irredeemably bad", giving the game a score of 1 out of 10.
