Reporting a broken game

Please include the game name, the browser and device you used (for example Chrome on a Chromebook), and what happened. A screenshot helps a lot.

Suggesting a game

We can only add games whose code and art are released under an open license that allows hosting. If you know of one, send us a link to its source code.

Asking for a game to be unblocked at school

We cannot change your school’s network settings, and we will not help get around them. If you think the site is filtered by mistake, ask your teacher or IT team to take a look. Point them to our safety guide, which explains that there are no downloads, accounts, chat or ads, and to the credits page listing every game’s open-source license.

Feedback on the site

Ideas for new categories, a game description that could be clearer, or a control that did not work as described are all welcome. Every game page is written and checked by hand, and reader reports are the fastest way we find mistakes.

Copyright and licensing

If you created a game listed here and want a change to its credits, or want it removed, email us from an address we can verify. We will respond quickly.

We usually reply within two to three working days.
