A 10-cent line, also known as a dime line, is a betting line where the line difference between the two possible outcomes is only ten cents.
When the two outcomes are each given the exact same chance of occurring, such as in most types of spread betting, a dime line would occur when both outcomes have odds of -105. For unequal outcomes, such as in most money line bets, it applies to lines where the two outcomes are within 10 cents of each other.
10-Cent Line Example
Here is an example of a 10-cent line from 5Dimes:
As you can see the difference between the Montreal Canadiens (favourite at -120) and Detroit Red Wings (underdog at +110) is only ten. If you bet a dollar on the Red Wings you could expect to win $1.10 if they won the game, while you would have to risk $1.20 to win $1.00 betting on the Canadiens. This difference between the $1.20 risked on the Habs and the $1.10 you would potentially win on the Red Wings is ten cents.
10-Cent Lines for Sportsbooks
Another way to look at the 10-cent line is in terms of how much juice is taken by the sportsbook. The ten cent difference between the $1.20 and the $1.10 is the juice collected by the sportsbook. This is another way to look at why they call these 10-cent lines.
10-Cent vs 20-Cent Lines
20-cent lines are much more standard than 10-cent lines in the sports betting industry. 10-cent lines are generally very player friendly odds and can be very difficult to find.
Here is an example of the 20-cent line from the exact same game as above from 5Dimes:
As you can see a bet on the Red Wings earns 5 cents less per dollar, and you must risk an extra 5 cents to win a dollar betting on the Canadiens. The difference between the -125 and +105 is twenty cents.
At 5Dimes they offer 10-cent lines as reduced odds on many of the sports they offer, but the majority of online bookies will stick to 20-cent lines. For this reason, if you find a sportsbook with 10-cent lines I’d suggest signing up.
