The odds are a number that represents the probability of an outcome expressed as a price. They are usually displayed on the left side of the betting board at a sportsbook. In the United States, most top sportsbooks use American odds, which indicate how much you could win with a $100 bet on a team or individual player. Odds can also be positive (+) or negative (-), which reflect how much you would have to wager to win a given amount of money.

Prop bets are a type of wager on random events during a game, such as how a coin toss will land or how many points will be scored in a particular quarter. They can be placed at both physical and virtual sportsbooks. In addition to these wagers, a sportsbook can offer futures wagers. These bets are typically made on teams that will win a specific event, such as the Super Bowl, and have a long-term horizon with increasing payouts over time.
