Playfield was produced by Gottlieb as a 1 player replay version called 'El Dorado', an Add-A-Ball version called 'Gold Strike', an Add-A-Ball version for Italy called 'Lucky Strike', a 4 player replay called 'Target Alpha', a 4 player replay game made only for France called 'Canada Dry', and a 2 player replay called 'Solar City'. Also later produced as Premier's 1984 4 player 'El Dorado City of Gold'. We have increased our confirmed production run quantity to include 2 Sample games produced in 1975 that were not part of the former quantity per handwritten documentation identified by Wayne Neyens as coming from Bob Malvasio, a draftsman for Gottlieb whose initials RHM can be found on schematics. This documentation showed 1,013 Production games were made and not 1,014 as previously obtained from non-engineering documents.
