double jackpot time. Every 20 mins. a pitch man would say to players 5 mins to double jackpot time, with a count down 4-3-2-1 mins. Bells would ring and everyone would start playing slots as fast as they could, makeing sure they had cups full with .05, .25, or 1.00 coins ready to put in machine and pull the handle as fast as possible. Slots were fairly loose then, and bells would ring, pitchman yelling jackp pot machine #. They had drink girls all over serving free drinks in nice glasses, all with Pioneer advertising on outside of the glass, with pioneer Vic and casino picture. It was a exciting, and fun time to play. They created so much excitement, and the place was jammed. Mainly the old three wheeler slot's with 7.50 jackpot on .05 one coin machine. I loved old Vegas, now love the history. Thanks again for great site.
