They are commonly referred to as the puck line and the money line. Since hockey no longer has tie games it is more common to see the money line in hockey betting odds.
Detroit -170 5.5 under
If you like Anaheim in this particular hockey betting line example you are getting +150, meaning you win $150 for every $100 wagered or the 15-10 equivalent if the Ducks win. If you take Detroit you are risking $170 for every $100 you want to win in this NHL odds example.
The other main option in NHL odds is the puck line, and like the baseball run line, it has you laying the extra goal or half goal. For example, you might have Detroit laying -1.5 goals but instead of minus money you now get plus money in hockey odds. They might be -1.5 (+160) in hockey odds.
Anaheim would be getting 1.5 goals but now would be laying -180. In this case, if you liked Detroit, you would be giving a goal and a half to Anaheim and would have to win the bet by 2 goals or more to win. If you won by only one goal it would be a loss in hockey gambling odds.
If you took Anaheim, you would have to either win the game outright, or lose by only one goal. The total in NHL odds is also available and usually listed to the far right and that is the total amount of goals scored in the game.
If you see the word over or under it shows that extra money is required to bet that side in NHL betting odds.
So in the previous example if you liked the over you would risk even money but if you liked the under you would risk $120 for every $100 you wanted to win in hockey odds. Those are the basic NHL odds you are likely to see with hockey.
