A casino is a place where champagne glasses clink, people laugh and play cards and slots, and the smell of money and excitement fills the air. It’s a fun and lively atmosphere that can make even the most jaded of gamblers take a step back and marvel. But a casino’s not all about the games and the people, it’s also about making sure that players keep coming back to spend their money for the chance of winning.

That’s where security comes in. Security guards and dealers keep an eye on the patrons, making sure there’s no blatant cheating like palming or marking. They’re also watching to see if any players are losing too much. They’re also looking for betting patterns that may indicate a casino employee is colluding with another player. Each table manager and pit boss also has a higher-up person keeping tabs on their activities.

Casinos know their house edges and variance for every game they offer, so they can calculate how much profit they expect to make. They use mathematicians and computer programmers that specialize in gaming analysis to do this work.

Casinos have a lot of things to offer their group clients, from hotel rooms to food and entertainment. But they need to be careful not to oversell because groups can be the most expensive customers for casinos. That’s where competitive ads for hotels come in handy, giving a casino prominent exposure when event planners are searching for solutions in their own areas or sister markets.
