1. The outcome is determined by a man sitting in the backroom. Each machine is an independently operating device. 2. It is no use to play further if a mechanic has opened the machine because the machine will pay nothing. There are no switches, knobs, or screws inside a machine that will change how the machine is paying. Most of the time a mechanic or floor-person will open a machine only to clear a coin jam or refill a hopper if you have won enough to empty it. 3. Playing one and the same machine for a long period of time guarantees that you will get paid soon. It may be "due" or even long "overdue," but that doesn't mean it is "ready" to hit. This game never influences the next one. You can play for 5 minutes and win the jackpot or play for several hours and win nothing. 4. With a club card you get paid more often. Club cards have nothing to do with the payout of the machine. Club cards will never make the machine pay. 5. The professional gambler has a better chance than the tourist. All players have equal chances of winning. The machine has no way of knowing if you are a tourist or a professional or if you are tall or short. The only edge a better player may have is his ability to choose the best cards to hold. How To Play Poker.
