Playground Sessions can be used when both online and offline.
When setting up your Playground Sessions account for the first time after purchase, you'll need an internet connection for the initial setup. Afterward, you'll also need an internet connection to download any of our lessons.
Once you've completed the initial setup process, you'll then be able to access any downloaded lessons offline. Keep in mind, when using the program offline, your scores and badges won't be synced to your account until you connect back to the internet.
