Playgrounds allow the game creators to create multiple screens with photo background and dynamically show icons on the background. In a device each playground can be accessed by clicking on the button on game screen. Playground can be zoomed together with pins. Clicking a pin will open a task.

The feature is in BETA and might not be available or is limited on your account.
