Build a gecko
Change genes and watch the gecko redraw. Start simple, or open every gene and set copies and strengths yourself. Share what you make with a link.
A CRESTED GECKO BREEDING GAME SHAPED BY GENETICS
Every gecko is different.
This gecko was drawn from its genes, not picked from a folder of artwork. The same genes always draw the same gecko, and changing one changes what you see.
The genes are the real ones. Gecktopia runs on a crested gecko genetics database built from published research and from what breeders have proven in their own projects, so a pairing here behaves the way it would in a rack.
Now imagine selectively breeding that variation for generations.

OPEN NOW, WHILE THE GAME IS BUILT
The genetics are already playable.
Gecktopia's renderer and its genetics are public while the game is in development. Nothing here is concept art: every gecko is drawn from its genes by the same renderer the game will use.
Read the morph library
Every morph the renderer draws, in plain words: what it looks like, where it shows on the animal, how it is inherited, and what happens when other genes join it.
Learn the genetics
Where each pattern lives on a crested gecko, and why. The same rules the renderer follows, written for someone who has never bred a gecko.
Follow the work
New morphs go live as they are drawn. What's new lists them, and the Dev Log covers the work behind them.
BUILT ON REAL GENETICS
The genetics are researched, not invented.
Which traits are genes, how each one is inherited, what is proven and what breeders still argue about, and which pairings are unsafe: it all comes from the same database that powers ReptiDex, a record keeper built for reptile breeders.
Crested gecko genetics is not a solved science, so the renderer has to make choices. Where the game simplifies something, or adds a gene the research does not name, it says so in writing.
A GAME ABOUT WHAT SURVIVES ACROSS GENERATIONS
A bloodline that becomes uniquely yours.
Gecktopia is a persistent crested gecko breeding and collection game built around inheritance, selective breeding, lineage, and discovery. Every gecko has a lasting biological and visual identity shaped by its genetics and ancestry.
Pair geckos, study the traits that appear across generations, and develop bloodlines in your own direction. Colors, patterns, structure, and other characteristics combine to produce animals with distinct identities. There is no single perfect gecko. The challenge is deciding what you want each line to become.
THE HEART OF GECKTOPIA
Inherited. Remembered. Connected.
01
Genetics
Traits are inherited across generations rather than randomly assigned.
02
Identity
Every gecko keeps a persistent appearance, ancestry, and individual history.
03
Lineage
Pedigrees preserve how colors, patterns, and traits develop through a bloodline.
WHAT WE ARE BUILDING TOWARD
A breeding project you keep.
These are the plans for the game, not features you can use today. The Dev Log follows each one as it is built.
Pair geckos and see what could hatch
Choose two animals and study the odds before you commit to a pairing, using the same genetics the renderer draws from.
Keep a bloodline
Pedigrees that remember how a trait entered your line and how it travelled, generation by generation.
Raise animals that stay themselves
A gecko keeps its appearance, its ancestry and its history. No two are the same, and none are reshuffled behind your back.
Discover what the species can do
The renderer is learning the whole genetic database, morph by morph, so the range you breed toward keeps growing.
FROM THE DEV LOG
What we have been building.
A Renderer That Reads Genetics
The renderer has been rebuilt. It no longer takes a list of appearance settings: it takes a gecko’s genes and works out what the animal should look like, using the same crested gecko genetics database that powers ReptiDex.
Patterns With a Memory
Gecktopia’s renderer can now dynamically generate unique pattern realizations for individual crested geckos. The animal on the homepage is no longer chosen from a library of finished sprites. It is assembled from a complete appearance recipe that can be reproduced whenever the same inputs return.
No More Patternless Geckos
Gecktopia began as an idea only a few weeks ago, but development is already in full swing.
