Identical playfield layout to INDER's 1979 'Topaz' but with a different artwork and theme. The theme and playfield layout are similar to Gottlieb's 1977 'Cleopatra'. This is an electromechanical game. Reportedly, the entire production run was fitted by the manufacturer with a kit that added a digital score display in front of factory-installed EM score reels. The kit also added a very basic sound board with a speaker instead of chimes. The credit and match score reels had digital numbers painted on them. Presumably, the kit was made by the manufacturer if it was installed by them, but we cannot yet confirm this. Keops (or Cheops) is a reference to King Cheops of Egypt or to the pyramid built for him.
