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. 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.

Club cards is not an exception here. Club cards will not help the machine to pay. 5. The professional gambler has a better chance than the tourist. 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.
