1. The machines are controlled by someone in the back room. In fact every machine, video poker or slot, has a device which operated independently. 2. It is no use to play further if a mechanic has opened the machine because the machine will pay nothing. In reality machine doesn’t know whether it has been opened or not. It is done either to clean or to refill the hopper of the machine. 3. "I have played this machine for hours-it is due to hit." 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. 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. Using a club card makes the machine pay more often. Club cards have nothing to do with the payout of the machine. Club cards will never make the machine pay. 5. A beginner or a tourist will never win more than a constant player. 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. American Poker Player.
