Just make a username for yourself. And when they ask a question to you, just press enter or you'll start the game on accident. Sorry about that. Destroy the aliens by answering math problems (the questions are super simple, so if you fail..uh...I think you need to go back to kindergarten.) To end it click log out and then it comes into a credit scene.
