As the white square, your job is to avoid the other squares that are bouncing around. Catch the small white square for an extra life. After losing a life (and after a short delay), press the fire button (or wait), to be placed back to the original position near the top-left of the playfield. The white square is bounded by the dotted line. Can you last long enough for the extra square(s) to appear? Good luck and have fun!
