App Center
App Center is the primary place to find great games. Every game listed on Facebook includes screenshots and videos of actual game play along with user ratings, which helps people see what makes a game interesting before installing and playing it.
App Center is a place to showcase fun, original games across a variety of genres. All games must apply for review and will need to be approved within App Center before people can play them on Facebook.com.
List your Web Game on Facebook.com
To get your Web game listed on Facebook.com and gain discoverability for your game, you'll need to create a game detail page and submit for review.

Image Assets
To ensure your game is represented well on Facebook, you need to upload icons, banners and screenshots for your app. These may vary based on the platforms the app supports. The image assets required will be displayed automatically in the App Details tab based on the supported platforms in the app's Basic Settings tab.
When creating your images, here are some guidelines to follow:
- Put the name of your app in the banner.
- Give important graphics some breathing space.
- Don't put logos and text against the border of images.
- Make sure banner images fill out the frame completely, and that they leave no white space, no rounded edges or no borders.
- Round the edges of icons - we recommend that you use transparency with PNG files, not GIF.
- Do not add badges such as "New", "Hot" or "Sale". Respect the way Facebook looks and functions. Don't offer experiences that change it.

App Center Review
The team uses a variety of signals, such as player ratings and engagement, to determine if a game should be listed on Facebook. Well-designed games that people enjoy will be prominently displayed. Games that receive poor ratings or don’t meet the quality guidelines won't be listed.
If your game is approved it may take up to 4 weeks and a minimum amount of players to be searchable in App Center.
How to submit for review
Once you have created your Details page you may submit your game for review.
Click on the Review tab under App Center, Start a Submission, and complete the App Verification notes. The Submit for Review button will become available once the app Details page and App Verification notes are ready.
App Review criteria
While we can never guarantee listing, your game may not be eligible because it:
- doesn't load or is broken in some other way
- doesn't meet the guidelines for images
- violates the Facebook Platform Terms and/or Developer Policies
- violates our Community Standards
- contains too many ads that detract from the experience
- is translated into a language that doesn’t match the given locale
- isn’t a strong fit for App Center
Login With App Center
The app detail page in Games displays the Facebook Login permissions requested from people new to your app. It can be considered a version of the Login Dialog in this capacity, making it easy for people to install your app directly from Games. You can configure the set of permissions your app requires in in the App Center Listed Platforms section of the App Details Page for that app.
The following fields are available when configuring permissions:
- Auth Token Parameter: When people launch your app through the App Details Page, we will pass your app the authentication token in the format specified here. Available formats:
URI Fragmentif your app uses JavaScript manual login flow.Query Stringif your app uses a server-side manual login flow.
- API Version: The version of the API used to authenticate new players via App Center.
- App Center permissions: These permissions will be displayed as required on the App Details Page in App Center.
If your app is a Facebook Web Game, we will not use this setting and will use the "signed_request" as the response type automatically.
While some people will be directed to an App Details Page from App Center, others may navigate to your app by directly entering your URL or through feed, requests and ads. In these cases you still need to handle login through the existing Login dialog.
If you would like to use the manual login flow with App Center it is important to make sure you are passing the redirect_uri parameter correctly when exchanging your code for an access token. You should set your redirect_uri parameter to the click-through URL to your site. In most cases the URL will look something like:
http://www.example.com/?fb_appcenter=1&fb_source=search&code=CODE_HERE
thus you should set your redirect_uri to the same value. Please make sure that this logic is dynamic as the query parameters appended to your click-through URL may be subject to change.
App Center Page Localization
The App Dashboard supports localization of the information about your app you enter in the App Details tab, such as the name you give it, the descriptions you provide, and so on.
People using your app will see text strings in the primary language selected on the App Details tab if you haven't translated your app detail page into their language.
To localize your App Center Page content, go to the App Dashboard, and select the app you want to localize. If App Center doesn't appear under Products in the left panel, click Add Product and choose App Center. Once you have done so, select Localize under the App Center header in the left panel.
If you have defined Custom Open Graph actions, your primary language must be set to English (US) and you should provide English content. You can still add additional languages so people other than native English speakers can read information about your app in the language of their own local Facebook version.
On the Localize tab, click Add Language to begin, and select a target language. You will be shown recommended languages based on where your app is popular. If you don't see the language you want, click All Languages in the left column and you'll be able to choose from any language Facebook supports.
When you select a specific language, you will see grayed out placeholder text from your primary language. Click it to select the text, and provide translations for tagline, description and detailed description. If you are requesting extended permissions and have entered an explanation for this in your primary language, you also need to translate it for each additional language. Display name and publisher are optional.
People viewing your app details on Facebook will see the translated text strings if using the relevant locale. Please note that if you translate your app information but not your app itself, you are required to list the supported languages in your app's detailed description.
The Localize tab also lets you upload localized icons, banners and screenshots. By default each new language that you add will inherit the images you added to the original version of your app in its primary language. These inherited images will be displayed as grayed out, to indicate that they are associated with your app's primary language. Any changes made to your primary language will also be carried over in all additional languages you have configured, and displayed on Facebook accordingly.
To override this behavior, upload language specific images in the Localize tab. These new images will be displayed in full color (not grayed out), indicating that they are localized versions. Changes made to images in the app created in your primary language will override localized images. To remove a localized image and return to inheriting images from the primary language version of your app, delete the localized image from the Localize tab.
Note: Non-English app detail pages aren't shown to people browsing the site in English.
More About Facebook Localization Tools
This guide describes only how to localize information about your app for display in Games in different locales other than the primary locale you created your app for. You may still need to translate text from your app into the languages for those locales. To learn about Facebook tools you can use to help translate your app, see Facebook Localization Tools.
If your app details haven't been localized, you also need to translate them.
