The first thing to know about a casino is that it has a built-in statistical advantage, or house edge. The edge is a small percentage that the casino holds over the game’s true odds. It varies for different games and is usually expressed as a percentage. The higher the house advantage, the more money the casino makes. But this advantage is small enough that it is easily ignored. The casino’s edge is not so great that you should avoid it at all costs.
In fact, the only way to make the odds in your favor is to be smart with your money. In other words, play for a positive house edge. This will reduce your short-term risk, while ensuring your casino’s profit over the long-run. It is not illegal to count cards while playing blackjack, but casinos will stop serving players if they suspect you are card counting. If there are fewer players in a casino, it is less likely that you will be detected and will be able to play for longer.
The second way to make your advantage in a casino’s games is to know its house edge. This is the average casino’s profit. The higher the house edge, the more likely you are to lose. But this isn’t a bad thing, as it only means that the house has an edge over you and the casino can afford to lose a few bets before you reach your goal. The longer you play, the higher the house edge will be.
