It’s happened to all of us: you stride into the Luxor or Mohegan Sun with your wallet full of cash and plans for a little enjoyable, sensible gaming and two rounds of cocktails. But hours later, you’re not sure what time it is or what happened to your money. It’s all thanks to the casinos—their sounds, lights, and physical design are designed to lead you into spending more money than you planned on. Here are nine tricks they use to keep you gambling and spending more than you should.

Casino is a story of greed and corruption, and there are no “good guys.” Sharon Stone’s portrayal of blonde hustler Ginger McKenna is one of the most compelling performances of her career, and De Niro gives a performance that is both frightening and sympathetic. The film is a reminder that in our world of increasing avarice, treachery and violence, good people are sucked up into the vortex of destruction.

When legalized casinos bring in large numbers of tourists, they can make a significant impact on the local economy. When tourists spend their money at local hotels, restaurants and attractions, it creates new jobs in the community. Casinos also attract skilled laborers and increase wages for the original less-skilled population, decreasing unemployment. However, some argue that the effect of a casino can be short-lived if the local population becomes too dependent on the casino’s income. This can happen if the casinos employ only a small percentage of the local workforce and do not offer any other employment opportunities.
