Rollercoaster Tycoon 4 Mobile is the first adaptation of the long-running amusement park management simulation for mobile devices. The core concept is identical. The player starts with an empty amusement park that can be designed with roads, attractions (merry-go-rounds, Ferris wheels, coasters etc.), shops and food stalls to run a successful amusement park, by keeping track of the customers' satisfaction and re-arranging or upgrading the attractions.
