1. The outcome is determined by a man sitting in the backroom. RNG which is an integral part of every machine works independently and nothing can affect it. 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. If you play a machine for a long time it is due to pay. One can’t know when the machine will decide to pay out. 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. The player club cards do not affect the operation of the machine. Club cards will not help the machine to pay. 5. A beginner or a tourist will never win more than a constant player. 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. Jackpot Poker Houses.
