The 2-player version of this game is Gottlieb's 1975 'Soccer'. The same cabinet artwork but in a different color can be found on Gottlieb's 1977 'Team One' and Gottlieb's 1977 'Kicker'. We show a date for this game of January 1975. One piece of Gottlieb documentation shows a date for this game of June 1975 but Cash Box Feb-22-1975 page 41 states Gottlieb had already wrapped up its overseas shipments of this game and its domestic deliveries were in progress. Gottlieb's documentation may have intended to indicate January 1975. According to the Gottlieb Engineering Game Cards, this game was ready to leave the Engineering Department in January 1975 for the production floor, and the next card dated April 1975 shows the game had already left the Engineering Department.
