Toggle App Builder / Game Maker
App Builder and Game Maker work hand-in-hand.
In AppShed you are always building an app. The app may contain normal "app" items (e.g. Text and Links) and it can also include Games. You can even have multiple app screens and multiple games within the same app. It is up to you how you want to structure your app.
Use the Toggle buttons to swap between the two modes to build your app+game.
