A playing surface may include a first boundary wall, a second boundary
wall, a first zone separator and a second zone separator. The second zone
separator may be spaced apart from the first zone separator in order to
provide a first zone area residing between the first zone separator and
the second zone separator. The zone separators may each have an angled
surface which are positioned so that a sphere may be rolled toward the
angled surface of the zone separator, roll over the zone separator and
into a zone area.
