It works by assigning a 1.5-goal spread to the favorite and the underdog. The favorite must win by more than 1.5 goals, while the underdog can lose by up to 1.5 goals or win the game outright for the bet to be successful. This format adds a layer of challenge or protection to hockey betting, depending on the side chosen.
Puckline Example
For example, if the New York Rangers are playing the Boston Bruins, the puckline might be set at -1.5 for the Rangers and +1.5 for the Bruins. If you bet on the Rangers, they need to win by two or more goals for your bet to succeed. If you bet on the Bruins, they can either win or lose by only one goal for your bet to win.
