The reason why casino still achieves high revenue even though customers win a lot of money

The casinos always take measures to prevent fraud, implicitly affect players’ psychology, to set the odds to maximize profits.
If you have a chance to enter the casino, keep an eye on your surroundings, you will probably discover how the dealer controls and influences every player’s experience: from the rules of each game, the music played through the speaker system, to the color of the carpet …

The rules of the game are depended on the house
The House always has rules that players must follow. Depending on the location, the rules for players in the casino may follow legal regulations to ensure the dealer does not go over the limit.
In a blackjack game, for example, a player can count cards to follow and determine which dealer or player has the advantage. This is a legal rule, but that doesn’t mean the dealer will like it.
In Atlantic City, New Jersey (USA), state law prohibits casinos from applying card counting. While the state of Nevada does not have any laws that protect such players in Las Vegas casinos. The dealer can ask the guest to stop or even ban it if they count the blackjack cards.

Lottery games often have the worst odds, with the house edge of up to 35%. The player’s odds are better in card and dice games. With blackjack, the dealer only has an advantage of about 1% to 2% on the good players, and increases to about 20% for amateurs.

Keep guests playing for as long as possible
Interior design conventions in casinos are increasingly evolving, but the unchanged goal is to get guests to stay for as long as possible. Traditionally, casinos often have no windows and clocks, and lighting is controlled in order to lose the sense of time for players. A casino makes almost no difference at 3am or 3pm.
Casino design consultant Bill Friedman revealed how interior arrangements also make a big difference to the casino space. This expert likes to turn the casino into a Muslim maze with short and narrow paths, wide horizontal game areas.
This design is not intended to mislead players, but instead to limit their vision and limit the scope of the game space. Friedman revealed that this will implicitly deceive visitors, causing them to walk around and discover many new games.

Roger Thomas has applied the same principle to the Slot Games room in the casino in Las Vegas. Initially, Thomas designed a space for an elderly male guest, giving it a dim-lit nightclub feeling. But then this architect discovered, the most frequent visitors to this room are women. Thomas installs windows to receive natural light providing an atmosphere that is more attractive to female guests.

Catch cheaters
Although the casino industry makes hundreds of billions of dollars a year, bosses have to work hard to suppress fraud. Immediately alerting the authorities if they suspect players are misconduct. In 2012, the Macau police arrested 17 people for defrauding HK $ 90 million from three casinos. The subjects include the dealer who uses a hidden camera to take pictures of the cards on the table.

In modern casinos around the world, placing surveillance cameras is a top priority design. To catch scammers, the casino trains staff to observe and detect suspicious signs. Beside, thay need to combine with a dense camera system throughout the ceiling. Most bookmakers have hundreds, even thousands of cameras, many cameras with 360-degree views, with a 24/7 live security team. Some places also use facial recognition technology to track suspicious people.
After all, the house always wins because casino is a business. They need interest to stay afloat. In addition, the ecosystem of casinos from resorts, hotels, spas, restaurants aimed at collecting money from customers. Therefore, many players need to be awake to stop the game at the right time.
