In most games that use an actual pinball as an intermediary between the captive ball and the ball in play (including the Pro version of this game), it is a non-scoring, static Newton ball post. Unusually, the Mummy captive ball feature on the Premium and Limited Edition versions of this game uses a switch-closing Newton ball target as the intermediary. Their Clairvoyant feature is a Newton ball target used as a stand-alone device (no adjacent captive ball). A limited run of 500 units was produced. Each Limited Edition game was autographed by designer Keith Elwin and came with a serialized number plate along with a Certificate of Authenticity signed by Gary Stern. MSRP when new: $8,999.00
