Casinos are exciting, dazzling places that are as much about socializing as they are about trying one’s hand at luck. People mingle and drink, the music blares, champagne glasses clink, and there’s just an incredible buzz. And that’s before you even get to the games, which range from poker and blackjack to roulette and slots. It’s a place where fortunes can be made and lost – but the good times are almost always guaranteed.

As any gambler knows, the key to successful gambling is to set limits for yourself and stick to them. You should also make sure to have a fixed amount of money you can afford to lose before walking onto the casino floor. It helps to change your cash into chips instead of actual dollars, as this dissociates the feeling of winning or losing with the actual money spent on betting. Many casinos also allow you to load money on a card to play digital games, which is another way to separate the feelings of winning and losing from the actual spending of real money.

But despite the glitz, glamour and opulence that fills every inch of the casino, it’s still easy to get sucked into the allure of winning big. That’s because casino managers are smart and use a variety of tricks to keep you gambling. From the scents to the sounds and physical design, Business Insider has rounded up nine ways that casinos trick you into spending more money than you should.
