Sportsbooks offer a variety of wagering options for their customers. The most popular are full-game odds, but there are also half-time odds, which are based on the first half of the game. These bets must be placed before the second half begins. Many sportsbooks also offer live-lines, which are constantly updated and changing according to game play. In recent years, in-game wagering has become increasingly popular.
The main source of profits for sportsbooks is vig. The vig is a fee that you pay the sportsbook each time you place a bet. It represents the difference between the odds and lines of the game and creates a profit zone for the sportsbook. This is most evident when betting on point spreads, which require you to bet more than you are willing to lose.
A great sportsbook will have comprehensive coverage of all major sports, including minor leagues, and events on every continent. It will also offer in-play betting and pre-match betting. Some sportsbooks will offer lines on everything from esports to table tennis. These sites also cover other popular sports such as politics and entertainment.
The best online sportsbooks will have a strong user interface and an easy-to-use layout. In addition, they should have fast, easy withdrawals, and a wide range of banking options. They should also have a solid reputation for treating their customers fairly and paying their customers on time.
