Bet sports 2000 Guest Says: A good example is what you see in las vegas sports betting where you see a football game and it shows you the point spread. The point spread may be -7 or +7 telling you a football team is favored by 7 points or an underdog by 7 points. So if you bet on the team that is -7, you must win by more then 7 to win the bet because you are giving 7 points. A tie gets your money back on the bet. The sports betting line may show -110, its usually -110, -105 or -115 as those are very common.
