When you think about Casino, you might imagine glitzy Las Vegas gambling halls with a variety of blackjack and roulette tables, plus hundreds of slot machines. But there are casinos all over the world, from elegant spa towns like Baden-Baden to big city attractions such as Leicester Square in London and the Venetian in Macau. Some casinos have even evolved into full-blown resorts where you can dine, see a show and then relax in a world class spa after hitting the slots.

Most games at casinos are pure chance, though some involve a small amount of skill. In either case, the house always has a mathematical advantage over players. This is known as the house edge. It is also possible to earn free goods or services at a casino, called comps, which are awarded based on the time you spend playing and your total stakes. Some casinos even give away airline tickets or hotel rooms to their most valued players.

Casinos depend on their customers for a large percentage of their gross revenue. So it’s no surprise that some patrons try to cheat, steal or bribe their way to a jackpot. That’s why casinos devote a lot of time and money to security. Security starts with dealers, who closely watch their games and can spot blatant cheating like palming cards or marking dice. Each table game also has a pit boss or manager who oversees the tables, watching for betting patterns that could indicate cheating.
