Gambling is a big business for casinos, with billions of dollars in profits raked in every year. These billions of dollars come from slot machines, blackjack, roulette, craps, keno and other games.

Most casinos are open 24 hours a day, which allows players to go in whenever they want to play a game. They are often staffed by professionals, and they use cameras to watch all of the games in progress.
