In Casino, Scorsese focuses on the mechanics of the casino business rather than gangster violence. His film lays bare the intricate network of corruption centered in Las Vegas with tendrils reaching into politicians, Teamsters unions, and even Midwest mafia based in Kansas City. The movie also reveals how casinos suck money out of the local economy and hurt property values in surrounding neighborhoods.

Casinos are designed to be visually stimulating with flashing lights, bright colors, and constant movement that encourage players to gamble. They also use sounds of coins dropping and triumphant music to make players feel like they are winning. This tactic creates a feeling of euphoria that increases the likelihood that people will stay longer and make irrational decisions. In addition, many casinos allow players to gamble with digital chips or credits instead of cash, which psychologically disconnects them from the amount they are spending and can lead to larger bets.

Lastly, casinos pump extra oxygen into the air and use pleasant scents to keep players alert and energized. They also strategically place toilets and restaurants deep within the gaming area to force players to walk past slot machines, tables, and other gambling opportunities. This strategy increases the chances that a player will make spur-of-the-moment decisions to gamble again, even when they have already reached their budget for the day. To avoid this, it is best to visit a casino when it is not busy and to control your bet size.
