Dragonvale is a simulation game made by Blackflip Studios for the iPod Touch, iPhone and iPad. Players create a park of Dragons in habitats to attract virtual visitors to their park. The player can breed, raise, and take care of their dragons. The park can be decorated with walkways, trees, decorations, and buildings which can be bought with money earned from their dragons. Dragons can be leveled up and yield more money. Basic dragon types are plant, earth, fire, lightning, cold, water, air and metal. These can be cross-bred to produce hybrid dragons. Rare dragons include sun, moon, and rainbow. Blackflip studios regularly introduces limited edition dragons.
