You've probably heard people say, "The longer we play, the better our chances of winning jackpot." But in reality, it’s often the opposite and such a mindset can be a trap. Each spin is a independent event, and every second doesn't increase your chances of winning in the next spin.
But I notice that although each spin is independent from each other, the longer one play on the same slot, the harder it is to trigger bonus round. I have experience this everytime I got hooked in one game. At the beginning bonus round can easily get triggered and often times normal spins give a huge win but the longer I staty on the same game the harder it is to hit even in a normal spin and the series of dead spin increases while hitting gives less and less winnings.
