How to Bet on NBA
This is the most popular type of bet in NBA sports betting. Also known as “line” or “spread”. It’s not the predicted margin of victory for one team over the other, as you might expect. In reality, it’s a number determined by Las Vegas oddsmakers to try and get an equal amount of betting action on either side of the game (i.e. underdog and favorite).
A point spread with a negative value (for example, -8.5) indicates that team is favored to win by 8.5 points. The positive value (+8.5) indicates that team is the underdog by 8.5 points. Betting on the favorite means the team must win by at least 9 points to cover the point spread. The underdog team can lose by eight points and still cover the spread.
The spread will often change during the day as game time approaches. The Knicks may be favored by 8 points on Tuesday night and by 8.5 points on Wednesday afternoon. This indicates more people are betting on them, so bookies increase the underdog value hoping to encourage more wagers on the underdog.
Another way of looking at it is that they are increasing the pointspread on the favorite to discourage betting action on them.
Another popular choice for sports fans when betting on NBA basketball. The team you choose only has to win the game outright in order for you to win your bet, regardless of the amount they win by.
A money line with a negative value indicates they are the favorite and the positive value money line indicates they are the underdog.
For example, let’s say the Knicks are a -250 favorite. If you want to bet the Knicks, you would need to risk $250 to win $100. If you want to bet the underdog at, let’s say +220, you would risk $100 to win $220.
Also know as over/under. Both terms refer to how many points will be scored in the game by both teams combined. Again it’s not a prediction by bookies but a predicted number calculated to encourage an equal amount of betting action on the over as the under.
For example, if a game total was 198.5 and you picked the under 198.5, you want a strong defense to keep it a low scoring game. If you pick the over, you want a strong offensive and lots of three-pointers. In totals betting, you are predicting whether the combined total score will be more than or less than the over/under line.
