Can AI make a game? Here are the ones it made on OrigoZero

Can AI make a game? Not a demo, not a clip of one, but a game you can open in a browser and play right now? The honest answer is a list, not an essay. Every world below was built on OrigoZero by a coding agent working inside the Zero engine: a person described what they wanted, the agent built it, looked at it, fixed what it saw, and published it to a link. Nothing here needs a download. Click a title and play.

The counts are launches on the site as of 20 September 2026.

Open world and driving

Grand Theft Auto VI, PS1 demake is the most played world on the site, with over five hundred launches. Vice City devolved to a PlayStation-era look: Lucia and Jason, open-world crime, police chases and a recreated reveal trailer. There is a whole post on how it was made.

Nürburgring Drive is the full 20.7 km Nordschleife with 240 Hz vehicle physics and lap and sector timing, ported from an open-source drive game.

Mow the Ring fuses that track with a mowing game: the whole Nordschleife is overgrown and your 200 km/h ride-on mower cuts a swath wherever you steer.

BIG STEAL CAR: ANDREAS-SAN compresses a third-person crime sandbox into one dead-end Tokyo backstreet, played in portrait.

Shooters and action

DOOM.wad is a multiplayer version of the first chapter of id Software's DOOM. The agent rebuilt the levels as engine content rather than replaying a map file; the write-up explains what that took.

SKYWARD: IRON HORIZON is first-person carrier combat: launch, dogfight, defend the fleet, strike an island, return.

Slag Saint is a one-fight boss game in a drowned bronze foundry, with a parry and a furnace-god chained in its basin.

Ultra Sniper Pro 9001 gives you a rooftop nest over a living plaza and six escalating contracts.

Horror and stealth

COINFALL is a PS1-era first-person horror roguelite set in a chained-up arcade where six coin pushers are still lit.

Lanternwake is Victorian gothic stealth in the fen: raise your lantern to read and work, and the Hollow Vicar can see you from across the water.

THE NIGHT CATALOGUE makes you the night guard of a museum with eight exhibits to sign in before five o'clock.

First Light: Vagant is a stealth-survival night on a drowned English fen, relighting seven lamp standards before dawn.

Strategy, cards and tactics

Greasepaint is a deckbuilding roguelite set on the last night of a travelling circus in 1931, voiced, played in portrait.

Escapement is turn-based tactics inside a colossal clock tower where the battlefield is the gear mechanism.

Hollowbell is an isometric action RPG: three chambers of the risen dead and a lantern-headed warhammer.

Trebuchet Castle Siege has you lay a counterweight trebuchet, read the wind, and bring a stone castle down course by course.

Arcade, rhythm and physics toys

Retro Arcade is an arcade cabinet running three complete console emulators written in Luau: Game Boy, NES and CHIP-8.

Sengoku Trance has Oda Nobunaga conquer Japan by out-raving his rivals in a four-lane psytrance rhythm game.

Dogeza Championship is a competitive apology gauntlet: hold to lower your forehead, release inside the green band.

Ball & Chain Demolition Co. swings a crane's wrecking ball through eight contracts without flattening the neighbours.

Neil the Seal is one tonne of trouble flopping through a cozy voxel beach town.

Pollen Fury makes you the giant birch tree aiming pollen clouds over a town to chain sneezes into combos.

Simulations that are not quite games

Fruit Fly runs the complete male fruit fly nervous system, 164,587 neurons, as a GPU spiking network driving an embodied fly. It is the most searched-for world on the site, and there is a post about it.

Small Brain. Big Clean. puts a trained fly-neuron circuit at the joystick of a Roomba with an apartment to clean.

Colony: Ant Sandbox is a top-down god game where hundreds of ants self-organise pheromone trails.

Sauna Master is a first-person Finnish sauna simulator: tend the stove, throw water on the stones, work the vents.

Helsinki is the real city from Helsinki's own 3D model, with the 2025 orthophoto on the terrain and textured buildings from Pasila to the shore.

So, can AI make a game?

It made these, and the catalogue has more than a hundred others across racing, cinematics, tech demos and visual novels. Some are small, some are rough, and the best ones are genuinely fun, which is the only test that matters.

If you want to make your own, you do not need an engine background. Open the AI game generator, describe the game, and watch an agent build it live. If you already use Claude Code, Cursor or Codex, connect it to the engine and it can build, run and publish worlds like the ones above. Every world here can be forked, so the quickest start of all is to open one and ask your agent for something like it.
