1. The machines are controlled by someone in the back room. Each machine is an independently operating device. 2. When a mechanic opens a machine, it will stop paying. In fact the machine will never ‘feel’ that it has been opened. Even if a casino person opens the machine he does it to clear or to refill the hopper of the machine. 3. "I have played this machine for hours-it is due to hit." In fact nothing can influence the time of payout. The previous game has nothing to do with the following one. 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. With a club card you get paid more often. Nothing can affect the operation of the machine. Club cards is not an exception here. They will not cause the machine to pay more or less often. 5. A constant player has more chances of winning that a beginner or a tourist. Every player has the same chance 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.
