1. Somebody sits in the backroom and control the work of the machine. 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. It is done either to clean or to refill the hopper of the machine. 3. If you play a machine for a long time it is due to pay. It may be "due" or even long "overdue," but that doesn't mean it is "ready" to hit. Every play is completely independent of every other play. 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. Nothing can affect the operation of the machine. Club cards is not an exception here. Club cards will never make the machine pay. 5. The professional gambler has a better chance than the tourist. The chances of every player are the same. 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.
