Uploading a game

1. Create the game

Open My games, type a title and press Create game. This makes a private draft.

2. Upload a version

A version can contain a browser build, downloads, or both.

• Browser build: choose the folder (or a .zip of it) that contains index.html. The game will run on its page.
• Downloads: one file each for Windows, Mac and Linux: a .zip, an installer or an executable.

Write a line about what changed and press Upload version. Large files upload in pieces, and a piece that fails is tried again a few times.

3. Wait for the checks

Every version is scanned for malware and started in a real browser, on a desktop-sized and a phone-sized screen. This usually takes a few minutes and can take up to an hour. The page shows the result for each check. If a check fails you are told why; fix the build and upload again.

4. Fill in the store page

Under Store page add a cover picture, a one-sentence tagline, a genre, an age rating and the AI label. A game cannot be public without these.

5. Go public

Your first game is reviewed by a person, usually within a day. Later versions go public when the checks pass, if Publish as soon as the checks pass is ticked. You can always go back to an earlier version with Make live.
