A casino is more than just a place to gamble. These casinos teem with restaurants, bars, shops, spas, museums and theaters all under one roof. Some ooze history while others are glass-and-steel temples of overindulgence. Regardless of their aesthetic, however, casinos share the same appeal: they are all about making you feel good.

This feeling is often induced by booze. Booze lowers inhibitions and clouds judgment, which is why you will find a bar or restaurant inside most casinos. This booze is served nonstop, right next to the blackjack tables or slot machines, and is often free. This booze is especially important to casino patrons because it gives them a false sense of possibility and keeps them betting.

Casinos also play on the sunk cost fallacy, which states that a person will continue to make a bet after a loss because the money spent on a previous losing bet is “sunk” and can’t be recovered. This mentality is often reinforced by the fact that casinos offer complimentary food and drinks to players, even if they lose money.

People that come to a casino to gamble are, on the surface, a pretty diverse bunch. There are the regulars who strut with confidence, expecting to win big, and there are the people trying to recoup their losses from the last round. Despite these differences, most gamblers have one thing in common: they want to have fun. With music blaring, champagne glasses clinking and people laughing, it’s hard to not get caught up in the vibe.
