"DragonVale" is a dragon breeding simulation game in which players design an island park and display dragons in habitats. Displaying dragons allows the player to earn "DragonCash". DragonCash can be used to upgrade a park with new islands, habitats, and decorations. Currently, the game has a max park level of 165, and there is a total dragon count of 709 (210 elemental dragons, 337 special dragons, and 294 epic dragons), decoration count of 524, and an island count of 32. Basic elemental dragons can produce a specific set of hybrid dragons  by being paired in the Breeding Cave, the Epic Breeding Island, the Berrywhite Breeding Cave, which is only available during Valentine's, the Cooperative Breeding Cave, and the Runic Breeding Cave, which is only available during Christmas time. The ten basic elements are Plant, Fire, Earth, Cold, Lightning, Water, Air, Metal, Light, and Dark. Epic dragons are rarer than basic elemental dragons and hybrids. The epic dragons include Sun, Moon, Rainbow, Treasure, Olympus, Gemstone, Dream, Seasonal, Apocalypse, Chrysalis, Ornamental, Crystalline, Snowflake, Monolith, Aura, Hidden, Galactic, Surface, Melody, and their epic offspring hybrids. There are a number of limited or rare  dragons, known as "Special Dragons", that are only available during a specific period of time. These dragons are themed toward specific holidays, seasons, DragonVale anniversaries, anomalies, months, and events. For example, the Ghost dragon is available for Halloween and the Reindeer dragon is available for the winter holidays. Another example is the Tien Dragon, which came out during the 10th anniversary of the creation of DragonVale. Many Epic dragons are also limited; for example, the Leap Year Dragon that is theoretically only available every 4 years. Limited dragons are often released alongside a limited park decoration. Limited dragons include the  gemstone dragons, which correspond to the monthly birthstones. Gemstone dragons earn gems rather than DragonCash. Backflip Studios has held several "bring them back" events to give players a chance to breed a limited dragon they may have missed the first time around. Gems are a vital part of DragonVale. Without them certain goals take longer to achieve. Gems can be acquired through trading them with friends, winning them in the colosseum and race track, purchasing them directly, or from gemstone and crystalline dragons. The Rift is another dimension in the game. In the Rift, Gems and DragonCash are useless and  the player must collect Etherium. The best way to collect Etherium is having dragons in the rift. The rift has a maximum of 55 habitats, which can be decorated using Rift habitat themes. Many dragons can go into the rift, but the rift has 35 special dragons. Though 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 unless they are the basic elemental dragons, for which you can use DragonCash. Alternatively, players can use Etherium to buy eggs of various rarity, ranging from normal  dragons to epic and limited dragons. Players can buy new islands to make space for more habitats although there is a limit on habitats. Players raise dragons to adulthood by feeding them treats grown from treat farms, won from the race track, or earned from the completion of quests. The higher level a dragon is, the more DragonCash it will earn per minute. Different dragons earn DragonCash at different rates. For example, a Gift dragon at level 10 can only earn 77 DragonCash per minute while a level 10 Moon Dragon can earn 256 DragonCash per minute. Rainbow Dragons can  earn 400 DragonCash per minute at level 10. Certain dragons can also receive earning boosts through different buildings, increasing the amount of DragonCash they earn per minute. 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, hatching or selling dragons after incubation, and other special provisions. These activities give the player a certain limited time currency that corresponds to the event and enables the player to buy exclusive or unique items. Critical reception.
