Sports betting is simply the act of wagering on the outcome of a sporting event. Sports bettors place their wagers on the results of games played by professional athletes, including football, basketball, baseball, hockey, and more.

The odds associated with sports betting are used to determine how much money bettors will win if their wager is successful. These odds are determined by bookmakers, who take into account a variety of factors when setting them. These factors can include the relative strength of the teams involved, the location of the game, weather conditions, and more.


The simplest form of betting is the moneyline, which replaces the point spread because the bookmaker is only interested in who wins the game. Moneylines are represented using a minus sign for favorites (-150) and a plus sign for underdogs (+130). So, if you bet $100 on Team A, you’d win $250 if they won (because you’d be paid back your original bet plus $150). If you bet on Team B, you’d win $380 (($100 x 3.80).

Point Spread

In order to place a bet, you need to understand what the odds are telling you. A typical sports betting line will look something like this:

New York Yankees (-110) vs. Boston Red Sox (+105)

The team listed on the left (-110) is called the favorite, while the team listed on the right (+105) is referred to as the underdog. In this instance, the Yankees are favored to win by a margin of 1.5 runs (called the point spread), while the Red Sox are underdogs by the same margin.

To bet on the favorite (Yankees), you need to risk $110 in order to win $100. To bet on the underdog (Red Sox), you only need to risk $100 in order to win $105.


In sports betting, the “over/under” is a type of bet that allows you to wager on the number of points, goals, runs, etc. that will be scored in a game. The “over/under” bet is actually two bets in one, an “over bet” and an “under bet” and you can usually choose which side of the bet you want to make.

For example, let’s say that the over/under for a football game is 42 points. If you take the over, you are betting that there will be more than 42 points scored in the game. If you take the under, you are betting that there will be 42 or fewer points scored.

If there are 41 points scored in the game, then those who took the under will win and those who took the over will lose. If there are 43 points scored, then those who took the over will win and those who took the under will lose. It doesn’t matter which team scores the points or how they score them, as long as there are more (or fewer) than 42 points scored in total.

The “over/under” bet is a great way to even out the sides in a betting matchup where one team may be much better than another and therefore more likely to win outright. By using the over/under bet, both sides of the matchup can be nearly even because each side is wagering on a different outcome.


In gambling, a parlay is a bet consisting of multiple bets that rewards successful bettors with a much larger payout than what they would normally receive from making the individual bets separately. For example, if someone were to parlay a $100 bet on three different games and all three of those games won, that person would receive a much larger payout than if they had made those same three bets separately.

Parlays are very popular among sports bettors because they offer the potential for large payouts while also being relatively easy to win. However, it should be noted that parlays are also very risky bets, as all it takes is for one of the underlying bets to lose in order for the entire parlay to lose.


A teaser is a type of bet that allows you to adjust the point spread or total in your favor. For example, let’s say you want to bet on the Patriots -3 against the Bills. With a standard bet, you would need New England to win by more than three points for you to win your bet.

With a teaser, you can lower the point spread to -1.5. Now, you would only need the Patriots to win by two points or more for you to cash in on your bet. The tradeoff is that you will get paid out at reduced odds. Teasers are usually offered at 6-point, 4-point and 3-point spreads.


Futures bets are wagers you make on events that will take place in the future. For example, you might bet on a team to win the World Series before the season starts, or you might bet on a horse to win the Kentucky Derby while the race is running.


So now that we know how sports betting odds are created, what do they mean?

The most important thing to remember is that the sportsbook is always looking to make money. They do this by setting lines that encourage equal betting on both sides. When the betting is balanced, the sportsbook will make a profit no matter who wins the game.

To do this, they will use what’s called the vigorish, or the vig. This is a small fee that they charge on each bet. For example, let’s say that you bet $100 on Team A to win and the odds are +100. This means that if Team A wins, you will get paid $200 ($100 bet plus $100 in winnings).

But because of the vig, the sportsbook will only pay you $190. This leaves them with a $10 profit. And if Team B wins, they keep your $100 bet. So regardless of who wins, the sportsbook always comes out ahead.

The key thing to remember is that the sportsbook always has an edge. This is why it’s so important to shop around for lines and to never bet more than you can afford to lose.
