Jurassic Park Builder is a freemium game consisting of two-dimensional landscape renderings and three-dimensional creatures. The player's objective is to build and maintain a Jurassic Park theme park. The player begins the game with a basic home base, while expansion of the park is done by clearing land. To create dinosaurs, the player must clear away trees and rocks to locate prehistoric mosquitos, which are trapped in amber and contain dinosaur DNA. In a laboratory, the player then attempts to unlock the DNA from the mosquito. If the player is successful, then a dinosaur egg is created. Amber is sometimes discovered when the player clears land for park expansion.
