DragonVale Sandbox


Incept Date

The DragonVale Sandbox was created in May 2017, following the retirement of the original Dragonvale Breeding Sandbox created by r0b0_tr0n aka Raymond Kirkland.

This is an independent, fan-created project and is not affiliated with or endorsed by Backflip Studios, the creators of DragonVale.

Breeding Rules

  1. Rule Zero — The breeding rules used by the DragonVale Sandbox are built from conjecture, experiment, and deduction. They are not canonical, and may be incomplete or inaccurate.
  2. Primary Rule — If a primary dragon is bred with another primary dragon of the same element, then the offspring is always a primary dragon of that element (e.g. Fire + Fire → Fire).
  3. Opposites Rule — A primary dragon cannot be bred with a primary dragon of the opposite element (e.g. Fire + Cold).
  4. Opposites Exception — However, if only two opposite elements are involved in a breeding pair (e.g. fire and cold), then the offspring may be a primary dragon of either element (e.g. Blue Fire + Frostfire → Fire or Cold).
  5. General Rule — Otherwise, the kinds of dragons being bred and all combinations of the elements they represent determines the pool of potential offspring. Each parent's kind is included in the pool, except for primary dragons (e.g. Fire + Sumi may produce a Sumi dragon, but not a Fire dragon).
  6. Limited Dragons — Some kinds of dragons are limited and cannot be bred except under specific circumstances (e.g. a Blue Moon dragon during a blue moon), if one of the parents is a dragon of that kind (i.e. you already have one, or can breed with a friend's dragon in the Cooperative Cave), or during a Bring 'Em Back event.
