On a 5x5 grid, several fields are lit for a short period of time. Your task is to remember what you saw and reproduce it. If you do that well, it gradually becomes more difficult (more fields are lit). If you make a mistake it costs you one of three "lives." Once your three lives are gone, the game is gone too.
