Casino security begins on the casino floor, where casino employees keep a close eye on patrons and the games. The dealers are trained to spot any signs of blatant cheating, and table managers and pit bosses are trained to keep an eye on table games. They can track the betting patterns of players and record video feeds for later review. In addition, computer chips control the payouts of slot machines, which eliminates the need for human intervention.

Casino chips are a great convenience to casinos and players alike. Players are less likely to lose their money when they are using chips, and they tend to play longer if they are able to spend less than their chips. This means more money for the casino. However, casinos are unlikely to ever replace these chips, which have a nostalgic appeal for players.

To avoid problems with gambling, casinos spend a lot of money on security. They hire computer programmers and mathematicians to calculate house edge and variance for various games. This work helps them know how much profit to expect and how much cash they need to keep in reserve. These workers are called gaming mathematicians and analysts. Most casinos don’t have in-house experts in this field, so they outsource the work to external experts.

When a casino offers a rewards program, they will let players earn points for playing games and earning comps. Comps can be used for cash or a variety of tangible rewards. For example, a player can receive a $50 bonus for playing a game at a particular casino.
