However new gamblers are the ones that do fall on this kind of tricks because they don't likely know that that winning in gamble is a luck thing.
You said it, in slots everything is luck, I do not deny it, there are many strategies that sometimes do make a difference, but this falls into the classification of luck, for protca bets things change, it is no longer the same, there are more options to win, and if you have a good analysis and are accurate it is possible that things can make the gambler win, but games like slots, roulette, it is difficult, yes things can be achieved, but what I recommend is to bet little money so that we do not go through bad times and without money.
