Contact GN Math

The fastest way to reach us is email: contact@gnsmath.com. We read every message and usually reply within a few days. To help us act quickly, include the details listed below for your type of request.

Report a broken game

Tell us the game name or page address, the browser and device you used (for example, Chrome on a school Chromebook), and what happened: a blank screen, controls that do nothing, or sound problems. A screenshot helps. Most problems are fixed by updating the browser or trying the fullscreen button, so it is worth trying those first.

Fix a mistake in a guide

If a controls table, tip or answer on a game page is wrong, let us know which page and what the correct behavior is. We check the game and its source code before changing anything.

Suggest a game

We only add games we can host ourselves under an open license. Send a link to the source code and point out its license for both the code and the art and sound. Games that need accounts, servers, or that copy characters from other games cannot be added. You can read the full process on the about page.

Copyright and license requests

If you believe something here uses your work without permission, or that our credits are incomplete, email us with the page address, what you own, and what you would like changed. We review every request promptly, and if there is a real problem we take the game down while we sort it out. Each game's license and source are listed on the credits page.
