This is a game that tests your reflexes. Upon starting a game the light turns red for one seconds, then the yellow light stays light for two to five seconds. Then, the green light comes on and you must click the button as fast as possible. Try to beat average and get the expert level reflexes, but dont click too soon or you will get a one second penalty.
One Vs One is similar, but it is a race to click the button first when it turns green. Instead of getting a one second penalty, you receive a minus one from your score.
