A dragon breeding game with real genetics

Breed dragons the way keepers breed ball pythons. Pair two dragons, read the odds on every egg, and prove the genes they hide, clutch by clutch.

How a clutch works

The whole game turns on one loop, and it stays the heart of it long after the first clutch.

  1. 1

    Pair

    Pick a female and a male. Before you breed, the game shows the odds of every look their eggs can hatch.

  2. 2

    Lay

    A clutch is one to six eggs. Close relatives cost eggs and hatch chance, and the game warns you before you pair them.

  3. 3

    Hatch

    Eggs warm in the incubator on a real clock, even while you're away. Crack them one at a time or all at once.

  4. 4

    Learn

    Every clutch is evidence. Two normal-looking parents that throw an Albino both carry it, and the game stamps them proven.

Morphs you breed, not buy

Every look comes from the genes a dragon inherited, one copy from each parent. The field guide holds 29 morphs today, and they stack: an Albino can be Striped, Masked and Piebald at once.

Every morph, and how to breed it ›

Hidden genes are the whole hobby

You never see a dragon's genes. You see its look, and what is known about it: het Albino for a proven carrier, 67% het Albino for one that might be.

Those numbers are real probabilities, worked out from a dragon's parents and from every clutch it has produced, and they move as it breeds. A run of normal babies makes a carrier unlikely, never impossible. One visual baby proves both parents at once.

Learning to read them is how keepers find the pairings worth running, and the dragons other keepers have overlooked. Hets and possible hets, explained.

A world of other keepers

Trade on the market

List dragons and sealed crates, make and counter offers, or swap directly. Scales stay in the game: there is no cash-out, and the seller's fee is burned.

Hatch a world first

The first keeper to hatch each morph in the field guide, or each colour-and-element square of the combinations book, holds that world first forever, on their profile for everyone to see.

Climb the leaderboards

Every keeper has a public profile with a showcase of up to six dragons. Leaderboards rank keepers by morphs discovered, world firsts, market volume and Mythic-or-better hatches.

Questions keepers ask

Is Dragonbred free to play?
Yes. You play free in your browser, starting with a pen of founder dragons and Scales, the currency you earn by playing. Optional purchases buy Embers, for the Iron and Lava crates, and Instant Cards that finish a clutch on the spot.
Do I need to know genetics?
No. A guided first clutch shows you how it works, and the game works out every percentage for you. When you want the theory, the Breeder's Journal explains recessive, dominant and super forms step by step.
Is it like breeding ball pythons?
On purpose. Genes are recessive, incomplete dominant or dominant, two copies of an incomplete dominant gene make a super form, and a dragon can carry a gene it doesn't show: a het. Reptile keepers will recognize every rule.
Can I play on my phone?
Yes. It runs in any modern browser, on a phone or a computer, and you can add it to your home screen like an app. Your pen lives on your account, so it is the same game everywhere you sign in.
Can I cash out Scales?
No. Scales and Embers have no cash value and stay inside the game. The market is keeper to keeper, and its 10% seller fee is burned rather than collected.
