Currently, there are 33 states and Washington DC with legal sports betting. There are also a handful of states that are considering joining the club in the near future.

There are a few key points to keep in mind when betting on official events. First, you must ensure that you are placing a bet on the right game.

For instance, a baseball game is considered official when it is completed after nine innings or eight and a half if the home team wins. This means that you must make sure the game is on time, at the right venue, and that the teams are playing to a final score.

Money lines are a great way to predict a matchup and can be used for many different types of wagers. When a game has extra innings, you can place bets on the total number of runs scored in the final innings.

You can also place money line bets on each team, allowing you to bet on which team will win the game. This is a great bet for fans of a particular team or player and can be very profitable when the betting odds are correct.

Unlike some other bet types, there are no limits on how much you can win or lose on a money line bet. However, you must be careful to choose a sportsbook that offers a money line for each game.

In the US, a number of state legislatures have mandated that to-be licensed sportsbooks purchase only “official league data” when offering live in-play wagering. While some believe the mandate is a good idea, others question its utility and reliability.
