Recessive
About this game
Build Your Foundation
One bedroom, two empty slots, and $1,500. Buy your first rack, stock it from the in-game marketplace, and unbox your starters — carefully, because food, cleaning, and upgrades all come out of the same pocket. Listings expire and refresh over time, but stacked animals rarely come cheap: the best genes are the ones you make.
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.
Earn the Clutch
These aren't vending machines. Males need a year; females need fifteen months and real body weight — push an underweight female and you gamble on permanently smaller clutches, infertility, or losing her entirely. Pair them, catch a breeding lock, and she's gravid: a month-plus to lay, then a long recovery while her eggs head to the incubator.
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.

Start with empty tubs and build a world-class ball python facility. Powered by a deep biology engine, calculate real genetics and experience the thrill of the hatch. Mint your snakes as digital assets to trade on the Steam Market!
