When a CEO or a big AI company makes a game with AI, it spreads fast, but the posts are mostly videos. This page collects the games by well-known people and companies that you can actually play in your browser, with nothing to download. For each one: who made it, which AI model they say they used, and what the game is like. Click a game card to play.

CORDON 9, by Perplexity CEO Aravind Srinivas
An endless first-person zombie shooter on a rain-soaked quarantine street, with a scoped rifle and a killstreak drone. Srinivas had an agent build it with Claude Fable 5.2, and the game has no asset files at all: everything is code.
Hogwarts Royale and Mirror Earth, by HyperWrite CEO Matt Shumer
Hogwarts Royale is a battle royale on broomsticks over a magic school, made from one line: "create a mashup of Harry Potter and Fortnite". It is an unofficial fan game. Mirror Earth puts the whole planet in voxels: go anywhere, break anything, and the weather follows the real Earth live.

Companies
Saltfire, by Higgsfield

Geminisland, by Google

Saltline, Tidewright and The Clockmaker's Heart, by Anthropic engineer Felix Rieseberg
Saltline is the one that went viral: a rain-soaked container-port FPS that Claude Fable 5.2 built from one prompt in about eight hours, every model and sound included. It is also the original of the game passed around in China as "Jimao, a Chinese AAA game". Rieseberg also made Tidewright, a night-sea sailing game about relighting lighthouses, and The Clockmaker's Heart, a gear puzzle.

FAQ
Are these really made by those people?
Each game is linked from the maker's own post, and every game page on VibeGamer links to it, so you can check the original. Which model was used is what the maker says in that post; when they did not say, we leave it out.
Are they free?
Yes. All 13 are free to play in a browser. Geminisland asks for a Google sign-in, the rest open straight away.
Which ones work on a phone?
Starfall and Turbo Tails list phone support, as does Saltline. The others are made for a computer with a keyboard and mouse.
