Point spread is a type of betting in basketball where the betting lines are set based on the difference in points between the two teams playing. The point spread is essentially a handicap given to the underdog team to even out the betting, with the favorite team needing to win by more than the spread, and the underdog team needing to either win or lose by less than the spread for the bet to be successful. For example, if the point spread is set at -7 for the favorite team and they win by 10 points, the bet would be successful. If they only win by 5 points, the bet would be unsuccessful. Point spread betting is one of the most popular ways to bet on basketball and is used in both professional and college leagues.
