A sportsbook is a place where people can make bets on sporting events. These bets can be placed on teams or individuals. In the past, sportsbooks were not widely available, but they have become more common since sports betting became legal in some states. A sportsbook can be found at a casino, racetrack, or online. A sportsbook offers odds on a variety of bets, including moneyline bets, spread bets, and prop bets.

In addition, a sportsbook should have a mobile app that allows players to bet on games from anywhere. It should also have a live chat feature that is available around the clock.
