How to Use Apps on Facebook
Because there are so many different apps answering so many different needs, Facebook apps included, it’s difficult to tell you what to do next. However, there are some common prompts and onscreen actions. Read on to find out what form these might take.
Application Home pages on Facebook
When you click a Play Game or Go to App button, you’ll likely be taken to the app's Home page. When you click a Visit website button, you’ll be taken to the app’s website in a separate browser tab or window.
You can see a sample Home page (for Candy Crush Saga). Its Home page basically prompts you to start playing the game. Notice that the blue bar is still at the top of the screen, which means that if you get bored playing this game, you can easily go back to your Facebook Home page or Timeline.
The left sidebar on your Home page is where you go to get to different parts of Facebook: your groups, News Feed, events, and so on. Links to the apps you use most often will also appear in the sidebar, with the ones you use most often at the top. Click the See More link in the sidebar and scroll down to see all your apps and games.
If you’ve used lots of apps over time, you might not even see all of them when you click See More. After you expanded the sidebar, scroll down to the Apps section and click the triangle icon next to the word Apps. The triangle should be pointed down when all your apps are displayed.
Invitations and requests
Just like you can invite friends to events; you can also invite friends to play games or use apps with you. After your friends are playing the same game as you or using the same application, you can send them requests for specific actions. For example, within many games, you can send requests to people for specific items they may have accumulated through their own play.
The beauty of games on Facebook is that you can play against your friends, which means they can be opponents in word games, generals in your online armies, or tellers in your online banks. When you ask them to take part or send them something within the game, the game can send them a request on your behalf. The confirmation dialog box shows what the actual request will look like.
Note the Don’t Ask Again before Sending Requests to <friend> check box below the preview. If you leave this check box selected, the app will be able to send that friend requests on your behalf as often as it wants. Clear this check box so that you always know when an app is sending your friend a request.
As you play games and use apps, you may also be prompted to post things to your Timeline. In this case, it’s a game prompting you to share that you completed another level. If you want to share these achievements with friends, that’s great; click the Share button and feel free to add your own comments to the text field.
If you’d rather not post to your Timeline about something like this, just click Cancel and continue on with whatever it was you were doing.
Lots of games on Facebook allow you to purchase virtual goods within the game. For example, if you haven’t yet gotten to the level needed to unlock an advantage in Candy Crush Saga, you could purchase that advantage (extra moves!) for a dollar or two. Some games create their own currency, which you buy, and some use Facebook Credits.
Facebook Credits is a payment system built by Facebook that other applications can incorporate into their service. Purchasing Facebook Credits is a way to purchase goods without sharing your credit card information with a million different game developers. Each credit costs ten cents, so one dollar gets you ten credits. Games may require different numbers of credits for different items.
Facebook Credits is just one of many payment systems you may come across while using apps.
