Then there's the confirmation bias, if we start to think that we are losing unnaturally lot, we start to notice every loss and our brains is wired so that it's telling me that we are doing something wrong or the game is rigged. Somehow we tend to forget that if there's a chance to won a lot, there must be a chance to lose as much and more. Somehow we don't think the game is rigged if we win a lot.
If you play long enough entually there will be a day when huge amount of your bets are going to be a losing bets in a row. It's just as certain that there will be a day you will win big. That's just probability statistics.
The reason why we tend to lose if we play longer is that we have a very limited bankroll to cover a losing streak. The casino has an unlimited fund that's why even if you win 100 times straight, you will still lose eventually because there's a that you will lose the same streak or more than the highest winning streak since it's a game of chance.
That's why it's better to set target profit and target lose everytime you will gamble to ensure that you can control your bankroll win or lose scenario.
Well, yes but since technically it's about about probability, there's a chance that casino doesn't win your money even in long run. It's just high probability, and with enough people playing, it's more likely casinos end up making profit. But i agree with your bankroll control methods. Setting limits to my playing is essential for keeping it fun. As it might have fun to gamble for the rush and fear. But those have too high stake real world consequences for me.
I think it has something to do with the house edge. I also experience that in playing slots, it is much easier to win in the beginning of the session while it is getting harder as the session gets longer. The series of dead spin also become longer, even reaching 20 consecutive dead spin which is not likely to happen when wee are just starting out our session. At the end we will emptied out our bankroll because of this pattern, 1 win against 20 or more consecutive losses. So I guess to avoid this kind of scenario, we should play different games in our entire gambling session.
