How Puck Lines Work

For those new to hockey betting, the puck line can feel like a confusing market. At its core, the puck line works like a simple point spread, fixed at -1.5 goals for the favorite and +1.5 for the underdog. The favorite must win by two or more goals to cover, while the underdog just needs to lose by a goal or win the outright. But because NHL overtime and shootouts add an extra goal to the final score, these 5-minute overtime stretches and unfettered shooters are always a factor.

The standard puck line is a favorite at -1.5 and an underdog at +1.5. The favorite has to beat the spread by two goals or more, which means they have to win by at least two¹. The underdog just has to keep it close, winning or losing by less than two goals². Like a point spread in a lower-scoring sport, the puck line provides a goal spread on top of the moneyline.

But in the NHL, overtime and shootouts complicate all that. During the regular season, any game still tied after a 5-minute sudden-death OT goes to a shootout³. The key difference is that the official final score does not list each round's goal. If tied 1-1 after 5 minutes of sudden-death overtime, the final score is instead recorded as 2-1, with the shootout winner getting that extra goal on the board⁴.

But after the shootout, the recorded score becomes 2-1, regardless of how the shooters performed. The official final score is adjusted with one extra goal for the winner, and no other goals are listed for those shootouts⁵.

In playoff games, there are no shootouts. Overtime extends at 20-minute intervals rather than the 5 minutes in regular-season games, and keeps on going until somebody breaks the tie.

Beyond the standard ±1.5 puck line, books occasionally offer alternatives. If the odds suggest the spread would move, you might find lines for -2.5, -1.5, +1.5, and +2.5. Example: if a 1.5-goal favorite was at +150 and some books might offer a -2.5 line as an alternative, with adjusted odds⁶. The increasing margin means an increasing probability of getting those goals, and those probabilities are why the juices swing more strongly. But these books are usually ±1.5.

A site's posted prices are good guidance, but they can be converted into percentages using a moneyline conversion formula. Positive prices use 100 divided by odds plus 100, and negative prices usually use the absolute odds numbers. So +150 means a 40.0% probability for the favorite profit, while -180 means 64.3% probability for the underdog's spread^7,8.

Even though hockey is lower-scoring, a person still has to remember the puck line isn't like a variable spread. The fixed 1.5-goal spread, and the NHL structure that makes puck lines so tough, are what makes the puck line feel so different. The final recorded score is the only number that matters; whether there are overtime goals or a shootout winner, when the puck line is +1.5, the final recorded score determines the outcome.
