A casino is a fun, upbeat environment filled with the clack of coins on slot machines, music and people having a great time. Whether they’re regulars who strut their stuff expecting to win big or newbies trying to break even, the crowd at a casino is pretty diverse, but all of them share one thing in common – they’re having a blast!

It seems like a crazy concept that normal, rational people would spend thousands of dollars on a roll of the dice or spin of the wheel. But it’s true – casinos are businesses, and they need to make money from their customers in order to be profitable. So how do they get people to throw hundreds, sometimes thousands of dollars away based on nothing more than a spin of the wheel or the flip of a card?

Obviously, they need to be able to keep you there as long as possible. That’s why you won’t see any clocks on the floor and the windows are usually tinted so you can’t tell what time it is. This trick helps people lose track of time so they can continue to play their luck for hours, or even days, without ever leaving the premises.

But that’s not the only way casinos are able to keep their patrons. They also offer a variety of comps and perks, including free hotel rooms, buffets, shows and more. This creates a situation where you’re so invested in your casino that you don’t want to leave, even for the basic needs of sleep and food.
