1. Somebody sits in the backroom and control the work of the machine.
RNG which is an integral part of every machine works independently and nothing can affect it.
2. It is no use to play further if a mechanic has opened the machine because the machine will pay nothing.
There are no switches, knobs, or screws inside a machine that will change how the machine is paying. 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. Playing one and the same machine for a long period of time guarantees that you will get paid soon.
One can’t know when the machine will decide to pay out. The previous game has nothing to do with the following one. It doesn't matter if you have played a machine for five minutes or five hours; every deal is from a full deck and the RNG (which selects each hand) has no memory of what has happened before.
4. With a club card you get paid more often.
Club cards have nothing to do with the payout of the machine. Club cards will never make the machine pay.
5. The professional gambler has a better chance than the 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. Online Draw Poker Hold.
