This game tests your ability to answer Addition sums within a quick period of time, you'll have different timers to set ranging from 30 seconds - 2 minutes, the game will display a series of sums for the player and they will have to enter the correct answer to score a point, if the answer is correct or wrong then the sum will change to make it harder for you. so you only get one shot to answer the sum. Good Luck!
