'Jack-Bot' is third in a series of games with a robot theme, including Williams' 1986 'PIN�BOT' and Williams' 1991 'The Machine: Bride of Pin�bot'. Some games in the production run were built using WPC-95 board sets. Two different playfield versions for this game are noticed, where just below the 5-bank of targets one version uses five arrow inserts that are all white in color, and the other version uses five arrow inserts of different colors. There also are two different plastics used above the entrance to the left ramp where it states "Lite Game Saucer Mega Ramp". One version is a simple light blue with pattern while the other is a fancier black and purple design. It is unknown to us which version of playfield and/or ramp plastic came first, or the reasons for them. Consider these variations: The flyer has colored arrows and the light blue ramp plastic. The promo poster has all white arrows and the light blue ramp plastic. One game pictured in this listing has white arrows and the blue & purple ramp plastic, while another game pictured here has the colored arrows and the light blue ramp plastic. In The Pinball Compendium 1982 to Present, Larry DeMar is quoted to say they had briefly considered naming this game "Lucky Star". Pictured in this listing is an example of each of the two cabinet color combinations produced for this game. One combination we refer to as "Red and Gold" and the other is "Gold and Yellow". The latter combination appears on all sides and cannot be attributed to "red fade" from the sun. Artist John Youssi told us that Python Anghelo left this project in mid-design and John and Doug Watson finished the game, with Doug doing the playfield art and John doing the backglass and cabinet art.
