When you start Educational Challenge and tap Start Game, you then select a category that you want to be quizzed on.

Next the app will ask you 10 random questions in that category. If you get them all right, you pass the challenge.

Along the way balloon icons on the bottom of the screen shows how well they are doing. A “Popped” balloon is given for wrong answers. In the end, only 10 right questions will get all ten balloons and a cheering crowd to congratulate the user for meeting the challenge.
