Puckline betting is hockey's version of a pointspread. The favorite on the puckline will usually be -1.5, meaning it must win by more than 1.5 goals, and the underdog will usually be +1.5, meaning it must lose by no more than 1.5 goals.
However, unlike moneyline wagering, the price on the favorite is often plus-money because the team must win by more than 1.5 goals, meaning the payout will be better. Conversely, the price on the underdog is minus-money because you’re getting 1.5 goals, your payout will be less.
For example, Team A is +1.5 on the puckline, with a price of -240, against Team B at -1.5 on the puckline, with a price of +200. That means for every $1 you want to win with a wager on Team +1.5, you must bet $2.40 and for every $1 wagered on Team B -1.5, you will win $2.00.
