Games played in casinos are called as casinos games. The casino games are three major categories: gaming machines, table games and random number games. Gaming games, such as slot machines and pachinko, are usually played by one player at a time and do not need the participation of casino workers to play. Table games, such as blackjack or craps, require one or two teams playing against the house (the casino itself) rather than each other. Table games are usually played by casino workers known as croupiers or dealers. Random number games are based on the generation of random numbers, either from a computerized random number generator or from other gaming devices. Random number games may be played at a table or by the buying of paper tickets or cards, such as keno or bingo. Some casino games incorporate multiple of the above aspects; for example, roulette is a dealer-driven table game featuring random numbers.
