The best AI browser games

There are thousands of AI browser games now, and most are rough prototypes. These are the 15 we would send a friend to first. They are free, play in a tab, and were built mostly by AI coding agents such as Claude Code, Cursor and Codex. Every pick links to a page with controls, how it was made, and the sources.
