Inspired by the 1994 Bullfrog title of the same name, Theme Park is an entirely new title using a 3D engine and free-to-play elements.
Players will upgrade their park's rides and staff using in-game currency, with aspects such as ride construction and park income taking place in real time.
Additional in-game currency can also be purchased with real money to access new attractions faster.
Parks will expand by buying new plots of land, which can be styled in a variety of ways including pirate, organic and futuristic themes, each offering their own for specific looks and ride-types.
As well as fine-tuning the specifics of each ride, they can be interacted with using touch controls, such as swinging pirate ships with swipes or prodding bouncy castles.
Elsewhere, there will be attractions based on other Electronic Arts titles, including Mass Effect, Dragon Age and Dead Space.
Theme Park will be available as a free universal application for iPhone and iPad by the end of the year, and will come with cloud storage for game progress using EA's social network Origin.
