About Dozen Games

Dozen Games is a free collection of 21 browser-based games you can play instantly — no download, no account required. Open a link, play. That's it.

Why browser games?

Most free game sites require you to install an app or create an account. Dozen Games doesn't. Every game runs directly in your browser using HTML5 Canvas. There's nothing to install and nothing to sign up for.

Because the games are pure HTML and JavaScript — no plugins, no Flash, no app — they work everywhere: school Chromebooks, work computers, iPhones, Android phones, tablets. If your browser can open a web page, it can run these games.

Works on school and work networks

Games like Snake, Flappy Bird, and Tower Defense are commonly blocked on school and workplace networks because they require app installs or come from known gaming domains. Dozen Games runs over a normal HTTPS connection — the same as any website — so it works on most school and office networks without any special setup.

No VPN. No proxy. Just open the link.

The games

There are 21 games across four categories:

Arcade & reflex

How the games are built

Every game on Dozen Games is built with plain HTML5, CSS, and JavaScript — no frameworks, no game engines, no third-party libraries. The gameplay runs on the browser's built-in <canvas> element. This keeps file sizes tiny (most games load in under 100 KB total) and means they work on any modern browser without plugins.

Because there's no server-side logic, the games continue to work even if your connection drops mid-game. Your score and progress live in your browser session.

Compared to app stores

App store games require installation (often 50–500 MB), account creation, and frequently contain in-app purchases or ads. Dozen Games is the opposite:

No installation — games open instantly in the browser
No account — nothing to sign up for or log in to
No in-app purchases — every feature is free
Works on any device with a browser — phone, tablet, laptop, desktop
