What does line mean in betting? Line betting is when a match is handicapped by a bookmaker. If the bookmaker believes there is a 3.5 point different between the two playing teams, you can bet on one team to win by more than 3.5 points or you can bet on the opposing team to lose by less than 3.5 points.

To win betting on sports, you must familiarize yourself with different betting markets. Professional bettors can find value in all areas of a game on the best online sportsbooks, which means they need to be able to target different markets on sports betting sites for different games.
