Learn about our Editorial Process Updated on 01/04/19 Of the four major sports, basketball is one of the easiest to bet on. Along with football, basketball uses the point spread for wagering on sides (teams), as well as an over/under number. If you know how to bet on football, you already pretty much know how to bet on basketball. The most common method of betting basketball involves the point spread, which is a handicap the sportsbooks impose on one team to make both teams equal in terms of betting. With the point spread, the team expected to win will be called the favorite, while the team expected to lose will be called the underdog. The team expected to win gives or lays, points to the team expected to lose for betting purposes. If the Celtics are playing the Knicks, most bettors would bet on the Celtics to win the game. But say the point spread will make the Celtics a 10-point favorite. What this means is that the Celtics have to win by 11 or more points for its bettors to win their bet, while those betting on the Knicks would win their wagers if the Knicks won the game or lost by nine points or less. If the Celtics win by exactly 10 points, the bet is a push or a tie, and no money changes hands. When betting against the point spread, bettors are asked to lay 11-to-10 odds, which means that they risk $11 to win $10. This is how the bookies and sportsbooks make their money. If I bet $11 on the Celtics and you bet $11 on the Knicks, the bookie collects $22 between us, but only returns $21 to the winner. The extra dollar is essentially the bookie's fee for accepting our wagers. Totals The second most popular method of wagering on basketball is in betting totals, also known as over/unders. Essentially, a total is the predicted combined score of the two teams playing. A number will be posted, and bettors have the option of wagering more than the predicted total points will be scored (over), or less than the predicted total points will be scored (under). In our hypothetical game between the Knicks and the Celtics, the over/under number might be 188. Bettors wagering on the over would win their bets if the total combined score were 189 or greater, while bettors wagering on the under would win their bets if the combined total score were 187 or fewer points. Again, if the combined score is exactly 188 points, the bet is considered a push, or a tie, and no money changes hands. Just as with the point spread, bettors are asked to lay 11-to-10 odds and risk $11 to win $10 on each over/under wager. Money Line Wagers While betting against the point spread or on totals make up the vast majority of basketball wagers, bettors also have several other betting options available to them. One is the money line wager, which is a bet on the winner of the game without the point spread. But because some teams are given a better than 50-percent chance of winning, money line wagers are made using odds, so that if you bet on the team expected to win you will be asked to risk considerably more than you stand to win. The money line odds on a game will look something like: Boston Celtics -300New York Knicks +240 What this means is that bettors taking the Celtics are asked to put up $30 to win $10, while those believing the Knicks will win are asked to risk $10 to win $24. All sports betting was done with money lines at one point, but with too many people betting on the obvious favorites all of the time, the point spread was introduced, and sports betting hasn't been the same since. Parlays and Teasers The other types of wagers involving basketball come in the form of parlays and teasers, which are sometimes called exotic bets. In parlays and teasers, bettors must correctly predict the winners of two or more games. On parlays, bettors have the option of betting against the point spread or using the money line, while teasers are made using the point spread and players can adjust the point spread in their favor. The one catch about parlays and teasers is that all of your teams must win or the entire bet is a loss. Even if you correctly pick five out of six games, a parlay or teaser wager is still a loss.
