Sportsbook

In the United States a sportsbook or a race and sports book (sometimes abbreviated as book) is a place where a gambler can wager on various sports competitions, including golf, football, basketball, baseball, hockey, soccer, horse racing, boxing, and mixed martial arts. The method of betting varies with the sport and the type of game. In the US, the Professional and Amateur Sports Protection Act of 1992 allows only Nevada, Oregon, Montana, and Delaware to legally wager on sports.

Winning bets are paid when the event finishes, or if not finished, when played long enough to become official; otherwise all bets are returned. This policy can cause some confusion since there can be a difference between what the sportsbook considers official and what the sports league consider official. Customers should carefully read the sportsbook rules before placing their bets.

The betting volume at sportsbooks varies throughout the year. Bettors have more interest in certain types of sports and increase the money wagered when those sports are in season. Major sporting events that don't follow a specific schedule, like boxing, can create peaks of activity for the sportsbooks.

Most of the United States sportsbooks are located in Nevada. Now that many casinos share the same parent company, they offer exactly the same wagering choices and odds, which is a disadvantage to the astute gambler who in the past could do more shopping for better prices.

In 1949, Nevada allowed bookmakers to accept bets on horse racing and professional sports. The first Nevada sportsbooks were called Turf Clubs. They were independent from the casinos and had an informal agreement with the hotels that they would stay out of the casino business as long as the hotels stayed out of the sportsbook business. The sportsbooks had to pay a 10 percent tax so they charged a high vigorish to gamblers, but they still brought enough business to make a profit.
