The Breeder's Shed

Gran's shed, its shelves of ledgers and tools. Everything here is built from the game's own code: its genetics, its coat painter, its breed standards and its calendar. Every rabbit you see here is painted exactly the way the game paints it.

Free, no account, nothing to install. What you make stays in your browser.

The Coat Lab

Pick two rabbits and see every kit they could have, painted, with the odds. A Punnett square for each gene, and a switch that hides genes the way the game does.

A rabbit colour genetics calculator

The Coat Atlas

Every coat the genes can make, on one wall. Tap one for its genes, its breeds, how rare it is, and a route to breed it from Gran's three.

Tick off what you've bred

The Breed Book

All 44 breed standards plus Gran's lost breed: what each asks for, what the judge looks at, and every coat that qualifies.

From the Holland Lop to the Rhinelander

Gran's Ledger

Build a pedigree up to five generations. See the inbreeding figure the game uses and how likely each rabbit is to carry each hidden gene.

Prints as a ledger page
