On a phone, players swipe left when they think the article in front of them is fake, and right when they believe it's real. On a laptop, they have buttons for "fake" or "true." You can click "view source" in case you need another clue about whether it was real or not. The article also tells you, after you make your choice, how you could have told if it was real for fake. Internet users should be required to take this, and pass it, before they are allowed to share news on Facebook.
