Casino security involves routines and patterns that the casino follows. Dealers, for example, shuffle the cards and deal them to each table. There are betting spots located on the table. Each motion can be predicted, making it easier for casino security to spot suspicious behavior. Casino employees are also closely monitored. This makes it harder for criminals to win. However, there are always ways to detect cheating. Security measures include cameras are not the only ways to protect casino patrons.

The casino has a built-in statistical edge, which can be as low as two percent. This advantage is sufficient to make the casino profitable, which is why they focus on attracting high rollers. High rollers usually gamble in special rooms, separated from the main casino floor. Their stakes are usually in the tens of thousands of dollars, and they receive comps. Comps range from free food to luxury suites, and personal attention.

Many casinos in the 21st century also feature games from Asian countries, such as fan-tan and sic bo. In the 1990s, these games reached Europe and the United States. Other local games are also offered. Popular ones include two-up, banca francesa, and boule.
