In this game, you will be shown some progress bars with random %. Now you will be asked a question about the progress bars value. You will be given additional help in the form of scope i.e. if progress bars value is 24 with a given scope of +-4. Then your answer will be valid if you type anything from 20 to 28. You have to answer the question by typing using an on-screen keyboard and submit it. Right answer will earn you one point. Wrong answer will end your game. There are 3 game modes, each having its own difficulties and reaction time.
