Before betting on a game, truly understand the rules of the game and what each move in the game is. Betting on a game entirely on a whim is the surest way of losing your money. Merely knowing the rules of the game does not make you an expert at it. Every game has a learning curve, and there is a sure way to master that technique. Most importantly, do not bet in casinos hoping to make money and see it as a means of entertainment, because the casino is always going to win in the long run.
