Upload rules

Short version: upload a real browser game you have the right to share, and keep it safe for players.

What you can upload

  • A single .html file, or a .zip of your game folder with an HTML start page.
  • Web game files only: HTML, JavaScript, CSS, images, audio, fonts, data files and WebAssembly.
  • Up to 500 files and 500 MB in total (unpacked).
  • A cover image in PNG, JPEG, WebP, GIF or AVIF format. SVG covers aren't accepted.

What gets blocked straight away

  • Programs, installers or archives hidden inside the game (such as .exe, .apk, .msi or zip files within the zip), even when renamed.
  • File types that don't belong in a web game, or a "cover image" that isn't really an image.

What gets held for a closer look

  • Password fields or anything that looks like a fake login page.
  • Known crypto-mining code.
  • Hidden, encoded code that runs itself.
  • Links that download programs or phone apps.

Content

  • Only upload games you made or have permission to share. Don't use other people's characters, music or art without the right to.
  • Tick the content warnings (violence, strong language, flashing lights) that apply to your game.
  • No hateful, sexual or illegal content, and nothing designed to trick or harm players.

Approval

Every game waits for a person to approve it before it becomes public. You can see where yours is up to on your My Games page. We may remove games that break these rules at any time.
