What is the NHL puck line?

The puck line is hockey's equivalent of a point spread, set at 1.5 goals. The favorite must win by 2+ goals; the underdog can lose by 1 or win outright. Because NHL games are low-scoring, puck line bets shift the odds significantly. A -170 moneyline favorite might be +115 on the puck line — you get better odds in exchange for the added requirement of winning by two.
