Security at a casino starts on the floor of the casino, where casino employees are constantly watching the patrons and games. The dealers keep an eye on players, and the pit bosses and table managers watch the games closely, looking for unusual betting patterns and other signs of cheating. Each employee has a supervisor who watches them and is trained to spot any unusual behavior.
Some casinos offer traditional games of the Far East, such as baccarat. In the 1990s, these games spread to European and American casinos. Other local games may also be found in Asian casinos. In Australia, two-up and banca francesa are popular games. In France, boule and kalooki are common.
Gambling is a very ancient activity and is often traced back to the primitive use of primitive dice, known as astragali. These early dice were carved from knuckle bones. In the 16th century, Venice became one of the first cities to officially license the establishment of a casino. During this time, aristocrats would gather in private clubs called ridotti. Gambling was a popular pastime for these aristocrats. However, since gambling was illegal, these nobles knew when to expect the Italian Inquisition.
While casino operators must be knowledgeable about the mathematical concepts behind casino games, they must also be sure to meet the reasonable expectations of players. Gambling is fun for adults and offers a fun and relaxing diversion from the realities of everyday life. Casinos often include elaborate themes that make them a popular destination for gamblers.
