Casino pit

A casino pit is an area of a casino which typically contains tables for Blackjack, Craps, Roulette, and other games.Typically, a pit is organized as two rows of gaming tables arranged back-to-back. The tables face outward toward a public aisleway. The space between the rows is restricted to dealers...

. The job of the pit boss is to watch the floormen, who are the supervisors for table games dealers in a casino. One pit boss monitors all floormen in the pit; there is usually one floorman for every three dealers. The floormen correct minor mistakes but if a serious gaming discrepancy arises (such as duplicate cards being found in a deck), it is the job of the pit boss to sort it out.
