These Ports are an important aspect of the Supaplex world. Murphy can pass through them, but other creatures (Snik-snaks and Electrons) can not. The Ports with one gray side wider than the other are one-way Ports. Murphy can pass though them, but only in the direction of the widest to the less wide gray edge. Ports with equal gray sides are two-way Ports. Murphy can pass through both sides. The four-way Port is not really a four-way Port, but rather a combination of two two-way Ports (i.e. Murphy can only pass straight through, and can not make a turn inside).
