Correctly select the pattern that matches with the target pattern at the top of the screen. There may be more than one correct answer (especially in the early levels). Guessing an incorrect pattern will cause you to lose a life. When all your lives are gone, the game is over. You have a limited amount of time to choose a pattern. If you run out of time you automatically lose a life. Picking the correct pattern will give you a variable amount of points based on how difficult the pattern was and how fast you picked the correct one. As the game progresses the patterns will become more and more difficult.
