Sportsbooks set puck line odds by accounting for the perceived difference in skill between the two teams, while also considering moneyline odds, which reflect the likelihood of a team winning outright. The puck line typically offers a -1.5 or +1.5 goal spread, meaning that the favored team must win by at least two goals to cover the spread, while the underdog can lose by one goal or win outright to cover. To establish these odds, sportsbooks analyze factors like team performance, head-to-head matchups, player injuries, and betting trends.
