I don't think there's a truly effective strategy, even if we constantly change it, because the percentage of losses is always greater than the percentage of wins. Instead of using or changing a strategy, we assume it works, when in reality, it's just luck or coincidence.
And if there was a strategy that worked, I think casinos would take action, because no casino wants to go bankrupt, and if there were, many gamblers would likely use the method they believe works.
And the best strategy is to change the way we play and always use money we can afford to lose, play at the right time and in a good mood to enjoy the game, and play just for fun, which sometimes brings luck. And when luck is on our side, we should stop immediately so we can win whatever amount. And always play with sufficient capital that has been set regularly, and when your capital is gone, stop even if you're losing.
