Are there essential things one must do when playing the slot?

[Sike_lottery]

I have seen so many people win jackpot in slot machine and I am always sceptical of how it happened. Are they doing some certain things that i am not doing? that is why I want to ask the questions if there is certain thing that must be done in order to win Big at the slot machine that one is not actually trying out. Your contribution will be highly appreciated.
