Abstract: A double match jackpot with (2) separate identical operating mechanisms in the machine is the invention. The two (2) identical mechanisms operate independently with no set combinations of play. Each play is with random results. A winning play is not determined by the number of plays made previously. The matching of two (2) identical symbols on pairs of facing discs determines a win. Operating sections can be attached separately to other identical operating sections to increase the odds in any play of the machine. Odds can be increased also by addition of identical symbols to the edges of facing discs.
