This quick tutorial will help you understand how to read a hockey betting line. Here is an example of one:
Detroit +105 +1.5(-270) Over 5.5 (+115)
Colorado -125 -1.5 (+230) Under 5.5 (-135)
The home team will always be listed on the bottom.
In the first column to the right of the team names you see a +105 next to Detroit and a -125 next to Colorado. This represents the money line if you take a team to win straight up. If you pick Detroit, your winnings would be higher. +105 means that if you bet $10 on Detroit to win straight up and you win your bet, you will get paid $10.50 in profit. If you take Colorado to win straight up, you will have to bet $12.50 to make $10.00 profit since their money line is -125.
In the 2nd column you see next to Detroit +1.5(-270). This means that Detroit is the underdog and if you bet them in this column, you will be getting a goal and a half. Basically if Colorado wins the game 4 to 3, you still win your bet, however the (-270) means that you will need to bet $27 to make $10 profit. The payout is small, but in a lot of cases it's the right pick.
Now the 2nd column of Colorado's line reads -1.5 (+230). This means if you take this bet, Colorado must win by 2 or more goals for you to win the bet. The upside to taking this bet is the payout. +230 means that if you bet $10 and win your bet, you will make $23 profit.
The over under line is the last column. In this game it is 5.5. That means that if both teams combine to score more than 5.5 goals (which is obviously 6 in this case) the OVER would be the winning bet. If 5 goals or less are scored the UNDER is the winning bet. The over in this case i (+115) which means that if you bet $10, you would make $11.50 profit. The under is (-135) which means you have to bet $13.50 to make $10 profit.
