When a bookmaker assigns a handicap to a game, that’s called line betting. You may bet that a team will win by more than 5.5 points if they are 5.5 points better than their opponent. Bet for the other team to win or lose by 5.5 points or less.
If 5.5 points favor a team, and you bet on them, you’ll collect if they win by 6 points or more. If 5.5 points favor a team, and your team losses by 5 points or less, or your team wins the game outright, your Bet will be a winner.
