What Is a Browser Game?
A browser game is a video game you play directly in a web browser, like Chrome, Safari, Firefox or Edge. There's nothing to download or install: you open a link and the game starts. Most browser games are free and work on any computer, and many also run on phones and tablets.
A newer kind is the AI browser game: a browser game built with AI tools like Claude, GPT or Grok. You can play 225 of them for free on AI Built Games.
How browser games work
A browser game is a web page. When you open it, your browser downloads the game's code and runs it, just like it runs any other website. Modern browser games are built with standard web technology:
- HTML5 and JavaScript for the game logic and controls.
- Canvas and WebGL for 2D and 3D graphics, often through libraries like Three.js or Phaser.
- WebAssembly for heavier games, including ones exported from engines like Unity and Godot.
- WebSockets for real-time multiplayer.
Older browser games ran on plugins like Adobe Flash. Flash support ended in 2020, and today's browser games run natively with no plugin.
Browser games vs downloaded games
- No install. Click a link and play, with no installer, updates or storage space needed.
- Works almost anywhere. The same game runs on Windows, Mac, Linux, Chromebooks and often mobile.
- Easy to share. A browser game is just a URL you can send to a friend.
- Usually smaller. Browser games tend to be lighter and quicker to play than big console or PC titles, though 3D and multiplayer browser games are now common.
Types of browser games
Browser games cover almost every genre. Common types include:
- Arcade and casual games: quick sessions you can play in a few minutes.
- Puzzle games: logic, word and matching games.
- Racing and driving games: from simple 2D racers to 3D driving simulators.
- Shooters: first-person and top-down action games.
- Simulation and strategy games: flight sims, city builders and tactics games.
- Multiplayer (.io) games: real-time games where you play against other people in the same browser tab.

What is an AI browser game?
An AI browser game is a browser game that was made with the help of AI. Instead of writing every line of code by hand, the creator describes the game to an AI model like Claude, GPT, Grok or Gemini, plays what it builds, and asks for changes until the game feels right. This way of building is known as vibe coding.
The browser is the natural home for these games. AI models are very good at writing JavaScript, and a finished game is a single web page that can be published for free and shared with a link. That's why a small team, or one person in an afternoon, can now ship a playable 3D game.
You'll also see "AI browser game" used for games where AI is part of the gameplay, such as opponents controlled by AI or stories that an AI writes as you play. On AI Built Games, the focus is games that were built with AI.
