Official betting, or “live” betting, is a type of wagering that occurs during a game’s live broadcast. This can be a fun way to make wagers on games while they’re in progress and can also provide additional betting value if your team is performing well during the game.

Most sportsbooks offer a variety of different types of official betting on a wide range of sporting events. The most common are money lines, totals and spreads. In addition, most sportsbooks also offer in-play betting, allowing bettors to place wagers as the game is going on.

In-play betting is a very popular way to place wagers on NFL games. It can be a great way to get the most out of your bets by making them during the course of the game as each team makes adjustments and gains momentum in the contest.

There are a number of ways to place an in-play wager, including through a telephone, internet or tablet device. Some sites even offer live streaming of games, giving bettors the chance to watch the action unfold as it happens.

When it comes to sports, there are several laws in place to prevent bookies from utilizing inside information for betting purposes. This includes a prohibition on accepting or offering any form of bribe to fix a match or event. In addition, it’s illegal to use inside information to obstruct the free flow of information between two or more parties, which includes any attempt to influence a player in any manner that could affect his performance.

A number of states have passed legislation that requires to-be licensed sportsbooks to purchase only “official” league data for live in-play wagering, which means that the odds displayed by a sportsbook are accurate. These laws are designed to protect bettors and to ensure that sportsbooks are providing an honest experience to their customers.

This type of bet is most commonly made on NFL games, but it can also be placed on college and professional sports. The rules governing this type of bet vary from state to state, but most states require that all in-play bets have odds posted before the game starts.

There are also specific rules for accumulators, which can be a popular wager when you’re betting on a game that features multiple teams. These bets allow you to place a large bet on one team without affecting your overall wager.

These bets are only considered official if the team wins, or at least loses by a certain margin. This can be an excellent strategy for savvy bettors who know how to read the odds, as well as players who aren’t particularly knowledgeable about the sports.

The first step is to familiarize yourself with the rules of these bets. This will help you determine the best strategy to maximize your bets.

If you’re new to sports betting, don’t be afraid to ask questions or take advantage of the customer service available through most sportsbooks. They’re available 24 hours a day and can answer any question you have about the wagers you’re placing.
