In order to play you must know your addition skills well. This is how you play: Press the green flag button. When the question comes up type the letter in the parentheses corisponding to the thing you want to type. Here is the meanings of the choices there are on the questions. Easy - 1 problem per 5 seconds. Medium - 1 problem per 4 seconds. Hard - 1 problem per 3 seconds. Expert - 1 problem per 2 seconds. This is the same thing as Sprints just changed so it makes you do addition instead of multiplication or division. Have fun with my game! Be careful it may be laggy! This game has no music.
