Beneath flashing lights and free cocktails, casinos are built on a bedrock of mathematics, engineered to slowly bleed players of their cash. For years mathematically inclined minds have tried to turn the tables by leveraging probability and game theory. The truth is that there’s no way to beat the house. You just have to know the rules and be prepared to lose.

Casino is a true epic crime drama, a film that exposes the seedy underbelly of Las Vegas gambling and mob corruption in the 80s and 90s. Scorsese’s most violent work, Casino features scenes involving torture, car bombs, the murder of De Niro’s character and the deaths of several others. But the movie is less about gangster glory than it is about the rotten core of humanity that these people represent.

While many people still visit casinos to play the games, others come for the food, entertainment and amenities. With that in mind, casinos should focus on attracting group business and events to help boost their bottom line. Using Cvent’s Competitive Market Ads and Search Ads, casinos can get major exposure to event planners in similar markets or sister cities—along with their hotel competitors—in the moments when they are most likely to follow through on their searches. Combined with targeted messaging and ad placements, these ads give casinos the visibility they need to attract event business. Whether they’re offering luxurious hotels, cutting-edge technology, flexible meeting spaces or gourmet restaurants, casinos can attract the right event business with the right casino marketing strategies.
