Casino is a story of greed and corruption. Every key character is mired in violence, treachery, and avarice. But the movie is also a study of human tragedy. It shows how even the most well-meaning people can be swept up in the tide of opportunism and addiction.

The bright lights, blaring music and physical design of casinos create an environment that is both welcoming and hard to step away from. But if you’re smart, you’ll know how to spot the tricks they use to keep you spending your money.

For example, casinos often bury the bathrooms far from entrances to force patrons deeper into the casino. They serve plenty of booze, because it reduces inhibitions and clouds judgment. They don’t offer straight aisles leading to exits, but rather maze-like floors with lots of twists and turns. That way, if you need to leave, you’ll have to walk past many more opportunities to press your luck.

In addition, casinos use technology to ensure that they’re making a profit. They have chips with built-in microcircuitry that enable them to track exact amounts of bets minute by minute, so they can monitor for any statistical deviation. Roulette wheels are electronically monitored so that the house advantage is no greater than 1.4 percent, and some casinos require only 1 percent.

But for some players, that’s not enough. That’s why reputable casinos promote responsible gambling, by offering features like deposit limits and self-exclusion tools. In addition, they have a robust customer support system that provides help quickly and efficiently. This greatly improves user satisfaction and trust.
