Play homebrew SNES ROMs in your browser with our WebAssembly Snes9x core, or build your own with the CatGame 65816 devkit.
An evolutionary simulation of rabbit agents on an island. Watch natural selection unfold as genes for selfishness, speed, size, and fertility compete across generations.
An idle clicker about hyper-tech AI companies scraping the internet for human content and distilling rival AI models. Build your data empire, one scrape at a time.
A medieval village where every NPC has secrets, biases, and rumors. Build trust through conversation to uncover the truth lurking beneath Thornhaven.
A SimTower-inspired vertical empire builder. Stack offices, condos, hotels and restaurants, then push into sci-fi hyper-lifts and space elevators as you build to orbit.
A Factorio-inspired factory builder for AI transformer pipelines. Mine raw data, route tokens on conveyor belts through attention and FFN layers, and deploy intelligence at scale.
An infinite first-person voxel sandbox. Start with nothing, dig blocks to fill your inventory, and build anything you can imagine. Streaming 16ร16ร256 chunks, GLSL shaders with ambient occlusion, day/night cycle, survival inventory system, and full local persistence via IndexedDB.
The game of Go as a duel of minds. Seat humans, our procedural NEKO engine, and TypeSafe's Jev decision model at the same board โ or watch two Jev agents battle each other with your API key. SGF records and career stats, all in-browser.
Pilot a probe through a constellation built from the agent's real dream graph. Attune memory-stars to read what it learned, and weave orphan memories back into the pattern.
Procedural 3D cartridge art. Select a cart to play in the emulator.
CatGame-authored NES cartridges. Browser emulator coming soon โ ROMs are being built now.
