1. The machines are controlled by someone in the back room. 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. 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. In fact nothing can influence the time of payout. The previous game has nothing to do with the following one. You can play for 5 minutes and win the jackpot or play for several hours and win nothing. 4. Using a club card makes the machine pay 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 Tap.
