A casino, also known as a gambling hall or card room, is an establishment where people can gamble and play games of chance or skill. Usually, casinos feature multiple gaming tables, such as baccarat, roulette, blackjack, craps, and poker. Aside from gambling, some casinos offer dining, entertainment, and other amenities.

In order to ensure their own profitability, casinos employ a variety of techniques, some of which are not readily apparent. For example, in the game of roulette, casinos lower their advantage to less than 1 percent of the total amount wagered to entice large bettors. In games of chance such as blackjack and baccarat, the house’s edge is uniformly negative. In card games, the house makes money by taking a commission (or rake) from each hand played.

Regardless of the specifics of each game, one thing is always certain: the casino will come out ahead in the long run, thanks to built-in advantages. It is this virtual assurance of gross profit that allows casinos to offer their patrons extravagant inducements, such as free spectacular entertainment, transportation, elegant living quarters, and even reduced-fare transportation and hotel rooms. This, in turn, draws larger numbers of tourists and increases revenue.
