If a team is listed as +5.5 points, then your Bet will win if your team loses by 5 points or less or wins the game. Handicap draw is also an option in the alternative handicap markets meaning if the game is a draw after the handicap is applied, then this is the winning selection.
Line Betting places a point handicap on both teams with the intention of leveling the playing field. One team will receive a negative handicap and the other team will receive a positive handicap.
