The Casino’s Mathematical Bedrock

Beneath the flashing lights and free drinks, casinos stand on a bedrock of mathematics, engineered to slowly bleed their patrons of cash. For years, mathematically inclined minds have tried to turn the tables, using their knowledge of probability and game theory to exploit weaknesses in a rigged system.

The games that casinos offer have mathematically determined odds that ensure that the casino will always have a profit margin, even in cases where there is an element of skill (such as blackjack). This advantage is called the house edge and can be reduced by the players using basic strategy, which is not complex, or with other techniques such as card counting. Casinos also earn money by imposing a commission on some games, such as poker, that are not played against the house, known as rake.

While some casinos offer a wide variety of attractions to lure customers, others have more streamlined operations. In the United States, the most profitable casino activities are slot machines and video poker machines, which produce high volumes of play at sums ranging from five cents to a dollar. Other popular activities include roulette, craps, and blackjack, where the house’s edge can be less than 1 percent.

Casinos are often located in exotic locales like Venice, Monaco, and Singapore. They pair these destinations with a promise of an unforgettable experience that includes luxurious accommodations, stage shows, and dramatic scenery. Despite this lavish appeal, most casino customers are driven primarily by emotional decisions. Consumers trust their friends and neighbors more than they do brands, and word-of-mouth recommendations and online reviews are extremely important to casino marketing success.
