First, I always try to analyze the rules of the game and calculate the probabilities of various outcomes. For example, if it's a roulette wheel, I study the probabilities of getting a certain number or color. Secondly, I control my bankroll and only bet what I can afford to lose. It is important not to take more risks than you can afford. I also try to look for games with the most favorable conditions for the player. For example, in some variants of blackjack or poker, you can use strategies that increase your chances of winning.
