Both greed and the illusion of control can make gamblers lose. Gambling is designed to favour the house in the long run, this is how the system is programmed. It's okay to have certain strategies but it's delusional to think that this is a guaranteed way that you can keep winning. Most people think they have a control over certain games especially when they are skilled based but this is actually a trap
Therefore, perhaps the best ways to win something in a casino are preferences in games where not only luck can influence the outcome of the game, but also the gambler himself, and these are games such as poker or blackjack.
However, these are games that require the ability to analyze and study in advance the strategy and general game approaches, so its are not for everyone.
If someone does not want to think and strain in a casino, then he should count on the fact that his chances of winning will be dictated solely by luck on this day.
