This game has a simple mechanism, but playing it is harder than you think! You are shown a simple equation (elementary arithmetic) and have a limited time to choose the right answer for it (there are 4 choices). Every correct answer earns you one score and your final score is based on the number of your correct answers. If you choose a wrong answer or run out of time, you will lose!
