1. Somebody sits in the backroom and control the work of the machine. Each machine is an independently operating device. 2. When a mechanic opens a machine, it will stop paying. 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. One can’t know when the machine will decide to pay out. Every play is completely independent of every other play. It can happen that a 5-minute game will bring you the jackpot and several hours spent at the machine will result only in losses. 4. If you have a club card you will win 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.
