Test your reflexes by touching moving spots before they disappear. Try to touch more than one at a time! The spots shrink as they move. The longer a spot is on the screen the harder it is to touch. Each higher level is reached by touching 10 spots. The spots move faster at higher levels, making the game increasingly challenging. You receive points (10 times the current level) for each touched spot. Accuracy is important--any touch that isn't on a spot decreases the score by 20 times the current level. You begin the game with three lives. If a spot disappears before it's touched, you lose a life. You gain a life for each new level reached, up to a maximum of seven lives. When all the lives are lost, the game ends.
