What is a puck line in hockey betting?
Short answer
Puck line = hockey's spread, almost always 1.5.-1.5 needs a 2-goal win.An overtime or shootout win is a 1-goal win.Empty-net goals swing a lot of puck lines.
The puck line is hockey's spread. It's 1.5 goals almost every game, and the odds change instead of the line, just like baseball's run line.

Overtime and shootouts
Puck line bets include overtime and the shootout. Every overtime or shootout win ends 1 goal apart, so the favorite at -1.5 can't cover in those games.
Empty-net goals
A team trailing by one late often pulls its goalie for an extra skater. That raises the chance of a tying goal and also the chance of an empty-net goal against. A 2-1 game can turn into 3-1 in the last minute, which flips the puck line.
My take
The puck line on a favorite pays plus money for a reason. Treat it as its own bet with its own price, not as a cheaper moneyline.
