Official betting involves placing a wager on an outcome in a specific competition. This type of betting is available through online sportsbooks and brick-and-mortar bookmakers. The odds on a particular outcome change in real-time as the number of bets on that outcome increases or decreases. This is also called parimutuel wagering.
Before making a decision on which sportsbook to use, be sure to research each site. User reviews can be helpful, but be sure to read them with a grain of salt. What one person may view as negative, another might see as positive (and vice versa).
The NHL has not officially taken a position on legal sports betting, but its expansion franchise in Nevada has already signed betting partnerships with bookmakers like William Hill and MGM Resorts International. The NHL is also smaller than the NBA and NFL, which could make it less vulnerable to the effects of legalized sports betting.
