Two Great Escapes

Jerry Lo

The world of the amoeba consists of the first quadrant of the plane divided into unit squares. Initially, a solitary amoeba is imprisoned in the square in the bottom left corner. The prison consists of six shaded squares, as shown in Figure 1. It is unguarded, and the Great Escape will have succeeded when the entire prison is unoccupied.
