Even if you already have a web game hosted on Facebook.com, or a mobile game on a mobile application storefront, you'll need to create a new app for your Instant Game. You cannot have an Instant Game running on the same Facebook App ID as any other app.
Go to the Basic Settings section of your app and make sure to set the category to Games. Save your changes.
As Facebook gradually rolls out Instant Games to a wider audience, your game may not be accessible to everyone. To ensure access for all of your developers and testers, add them as Administrators, Developers, or Testers of the Application in the Roles tab of the App Dashboard (see screenshot below). Learn more about roles.
Please Note: Do not add Instant Games to a pre-existing Facebook App configured for iOS, Android or Web. The Facebook App ID created for your Instant Game cannot be used for another platform.Create new Facebook App
To enable* Instant Games for the app, click the + Add Product button at the bottom of the navigation menu. This will open a list of products available to the app. Find Instant Games on the list and click the Get Started button. This will add an Instant Games section to the menu. Make sure to enable the the Use Instant Games toggle. Save your changes before continuing.
You can upload all of your game's assets and provide game information in the Instant Games section of the App Dashboard. Please note that all assets are mandatory your game will be rejected if any assets are not provided. Additionally, the game may not display correctly without all of the assets, so we recommend uploading all assets before testing your game.
You should provide a short - and ideally looped - video showcasing gameplay. We recommend 16:9 or 1:1 aspect ratios. Even if your game is in portrait mode, consider optimizing your video for these aspect ratios because News Feed stories are rendered in a landscape-oriented space. In those cases, consider cropping the gameplay video to a rectangular landscape portion of the screen or adding extra information to fill the sides of the video.
Remember, the video needs to showcase gameplay and should not look like an advertisement.
This image will be shown to players while they wait for the game to load. The image's resolution should be 750x1334.
Icons will appear in native dialogs on top of the game before and after each game session. It's important to have both game icons, otherwise the game will be shown with a default application icon.
Similar to the assets above, the Cover Image and the Banner are pieces of artwork that our platform needs to load in order to display our native dialogs, News Feed posts, and Messenger attachments correctly.
