Official betting is a type of sports wagering that is legal in most states, although some rules and regulations vary from state to state. Whether you’re a bettor or a sports fan, you need to be familiar with the laws and regulations of your state before placing any bets.

Several states have legalized sports betting since the US Supreme Court ruled in favor of the industry in 2018. New Jersey was one of the first to act and has nearly two dozen sportsbook apps available.

The Garden State has a long history of wagering on baseball. In fact, there was a 1906 betting scandal between the Massillon Tigers and Canton Bulldogs that led to a decline in the sport for many years.

Some states also allow betting on football games, although rules and regulations vary by jurisdiction. For example, some states permit pregame wagering on college games, but player props may not be permitted.

In addition, sports books are required to post odds that reflect the total number of runs scored in a game. This can be referred to as the over/under, and it’s usually used in conjunction with the moneyline.

The odds for these wagers can be found on the ticket or on the sportsbook’s website, and they fluctuate based on the total number of runs scored in a given game. The odds listed at the start of a game are official, but they can change during a game if the starting pitcher changes.
