Dragon Cave is a free adoptables site. The premise of DC is that you are a dragon trainer with a seemingly unlimited lifespan who collects dragon eggs and raises them to become adults.
Like many adoptables sites, the dragons are represented by graphics and are not actual living organisms, or even simulations. These graphics consist of sprites: small pixelated images-that "grow" on your scroll (the scroll being a list attributed to your personal account, consisting of your dragons and their statistics). Based on time, clicks, and views, the dragon will hatch and grow into an adult. If certain requirements are not met (x amount of clicks/views) within a set time period, the egg or hatchling will die.
There are many different breeds, or types, of dragons, and collectors are free to collect based on their own preferences. This can include single-breed scrolls, scrolls consisting only of rares or of their favorite breed(s), frozen hatchling "armies" (hordes of hatchlings that will never reach adulthood), or simply users trying to collect all breeds. Several dragons are secret or discontinued (see Dragon Types for more information), making the game much more interesting for users looking for "complete sets."
Players have the ability to breed two dragons to create a offspring having a 50% percent chance of being the same breed of their parent.
Some dragons cannot breed even if they have genders, these are classified as Unbreedables.
Players must also catch their own dragons by clicking on available dragon eggs, either from the main cave (index page) or the abandoned page. Eggs obtained from the front page (or "cave") are caveborn; these have no lineage, having come into existence mysteriously. The abandoned page (AP, as it is known to DC users) contains eggs that others have given up in some way. These may or may not have lineage, but it is far more likely to find dragons with parents or even large family lines in the AP.
Trading Dragons Edit
Since June 10, 2011, Magi Dragons have the Breed Specific Action Teleport, allowing for two-way trading or one-way transfering of up to four eggs/unfrozen hatchlings, effectively replacing Abandoned Page trading. Teleport has a two days cooldown.
