About this game

Build Your Foundation

One bedroom, two empty slots, and $1,500. Buy your first rack, stock it from the Steam Community Market or in-game marketplace, and unbox your starters — carefully, because food, cleaning, and upgrades all come out of the same pocket.

Play the Odds

A real inheritance engine, true to the hobby — dominants, incomplete dominants and supers, recessives, 50% and 66% possible hets, and hidden carriers you won't know about until they prove out. Run exact outcome percentages in the built-in genetic calculator, study the morph encyclopedia, and plan multi-generation projects that stack genes toward the combo you're chasing.

Hatch Your Reward

Two months of incubation until the eggs pip — then you open each one yourself. Did you hit the visual, or another round of hets to prove out with a shed DNA test? Every snake is procedurally drawn from its genes, so no two animals ever look alike — and once in a lifetime, a glowing Shiny worth a fortune. A full family tree records every pairing behind every egg.

Run the Operation

Living animals, daily stakes: feeding, dirty tubs, illness, sheds, old age. Sell on the market, hit cash milestones, automate feeding and cleaning as you scale, and expand from a bedroom hobby into a full breeding facility — while keeping the producers your whole program depends on.

Mint & Trade on Steam

Tag a snake you bred to mint it as a real item in your Steam Inventory. It leaves your save for good and becomes a tradeable, marketable asset — and tags are scarce, dropping on a timer, so mint only your best. Trade a starter to a new keeper, list a multi-gene female on the Community Market, or import another breeder's bloodline into your own collection. See how far a line you built by hand can travel.
