DragonVale is a park management simulator video game originally developed by Backflip Studios and released on September 14, 2011, for iOS and on November 9, 2012, for Android.
The ten basic elements are Plant, Fire, Earth, Cold, Lightning, Water, Air, Metal, Light, and Dark.
The epic dragons include Sun, Moon, Rainbow, Treasure, Olympus, Gemstone, Dream, Seasonal, Apocalypse, Chrysalis, Ornamental, Crystalline, Snowflake, Monolith, Aura, Hidden, Galactic, Surface, Melody, Zodiac, and their epic offspring hybrids.
These dragons are themed toward specific holidays, seasons, DragonVale anniversaries, anomalies, months, and events.
Backflip Studios held several "Bring Em Back" events to give players a chance to breed a limited dragon they may have missed the first time around.
Gems can be acquired through trading them with friends, winning them in the colosseum and race track, completing quests and goals, collecting from gemstone and crystalline dragons, or by purchasing them directly as an in-game-purchase.
Breeding is the most common way to earn non-basic dragons, they can also be bought from the market for a high amount of gems.
There have also been several events held in relation to time of year or holidays that require the player to do a number of activities like collecting DragonCash/Gems/Etherium, hatching or selling dragons after incubation, and other special provisions.
