Sports Betting Terms and Their Meanings

Added Game – A game that was not originally part of the rotation schedule. It could be a makeup game of a previously-scheduled contest or a game from a conference or league that is not consistently offered.
ATS (Against the Spread) – Betting with a point spread. You’re either adding points to the underdog’s final score total or subtracting points from the favorite’s final score total.
Backdoor Cover – When the point spread is determined by a score or event at the end of the game. It is most commonly used when an underdog earns a late score to cover the point spread.
Bankroll – Funds that you have allocated for the sole purpose of wagering.
Bookmaker– The person responsible for managing the betting lines and taking wagers.
Break Even Percentage – The percentage you need to win wagers in order to break even. (Not lose money)
Buying Points – Paying more money on the juice/vig to increase or decrease the points spread. Instead of laying the traditional -110 on a point spread, bettors can lay -120, -130, etc., in order to get a more favorable point spread.
Chalk – The favorite in an event. Chalk usually refers to the side that appears to be easy to predict.
Closing Line – The point spread of an event as it begins.
Closing Line Value (CLV) – A comparison between the line you bet an event at and the line the event closed at. Advanced bettors often grade their success based on the line that they versus what the closing line was.
Circled Game – A contest that has the attention of bookmakers because of an unknown, underlying factor that may greatly affect the point spread of moneyline odds. Factors such as an injury update, a potential trade, or an unexpected change to the starting lineup. Circled games often have lower betting limits.
Cover – When a bet wins due to the points spread. Either the favorite has won by enough points to cover the spread, or the underdog has stayed within the spread.
Consensus Line – The average spread and price at recreational sportsbooks.
Dime – Slang term for a $1,000 wager.
Dog – Short for “underdog.” The team that is not favored to win the event and the one receiving points on the point spread or plus-money on the moneyline.
Edge – A perceived advantage that a bettor can earn over the bookmaker. Or vice versa.
Expected Value – A predicted value of a variable, calculated as the sum of al possible values, each multiplied nut the probability of its occurrence.
Even Money – A bet with no juice or vig on either side. If the bettor risks $100 and wins, they will profit $100 and collect $200.
Favorite – The team whose odds have a higher implied probability. Favorites also lay points on the spread.
First-Half Bet – Making a wager on what the score will be at halftime. Most bookmakers offer first-half betting options in basketball, football, and baseball (known as a first-five bet).
Future – Betting on a long-term event. Future wagers can be team-related, such as winning a division, conference, or league championship. Or, they could be for an individual to win an MVP award, lead the league in passing, etc.
Grand Salami – A bet synonymous with hockey and baseball where bettors can wager on the total points scored in that day’s games. In hockey, bettors can choose whether the total goals in that day’s contest will go over or under the grand salami number. In baseball, bettors can wager on how many total runs will be scored on the day.
Handle – The total amount of money that the sportsbook has taken in for a given event or time period.
Hedging – Placing a bet on the opposite side of your original wager for the purpose of cutting your losses or guaranteeing a profit.
Hold Percentage – The margin sportsbooks take on both sides of the game.
Hook – The half-point attached to point spreads can make the difference between a winning wager and a losing one. If you bet on an underdog at +3.5 and they lose the game by three points, you won your bet “by the hook.” Conversely, if you bet on a favorite -7.5 and they only win by seven points, you lost “by the hook.”
House – Slang term for the bookmaker and staff behind the counter.
Implied Probability – The percent chance a bet has to win or cover the spread. The implied probability is tied to the price (ML) on each team.
Juice – The tax from the bookmaker for taking your bet. When making an individual bet on a football or basketball game, most sports books set the juice at -110. That means that you need to lay $110 to win $100 (collect $210). You need to lay $11 to win $10 (collect $21).
Key Numbers – The most common margin of victories, usually referenced when betting on football. The most common margin of victory in football is by three points or seven points. Therefore, bettors and oddsmakers pay keen attention when looking at point spreads around those key numbers.
Lay the Points – Betting on the favorite with the point spread and giving up points to the underdog.
Limit – The highest amount of money the bookmaker is willing to take on a given event. Limits generally increase the closer an event is to the beginning.
Line – Slang term for the point spread or odds.
Live Betting – Making wagers while the game or event is going on (i.e. betting on a golf tournament in the middle of a round or betting on a basketball game in the second quarter). Live betting is a relatively new endeavor for bookmakers and sports bettors but is considered to be a major market as technology grows.
Longshot – An unlikely underdog.
Middle – Middling occurs when groups who bet on the favorite AND the underdog at different point spreads both win. Group A bets on the favorite at -2.5, and two days later, when the spread is up to 3.5, Group B swoops in to take the underdog at +3.5. If the game ends 17-14, both groups have just won.
Money Line – Betting on the moneyline means you’re just picking the winner of the game, with no point spread or other factors involved. Since there is no point spread involved, betting on the favorite requires you to bet more to win a desired amount on the moneyline. Conversely, betting on an underdog on the moneyline will earn a larger profit.
Nickel – Slang term for a $500 wager.
Oddsmaker – The person responsible for setting the opening lines for an event.
Off the Board – The bookmaker has decided to suspend wagering on an event. Pulling a game off the board can be done because of injury news, a significant roster move, or another event.

Pick Em – A game between two evenly-matched teams where there is no point spread. Bettors are only tasked with picking a winner.
Point Spread – The point spread is the great equalizer. Betting on the favorite with the point spread requires that team to win the contest by a certain amount of points. Betting on the underdog with the point spread will allow that team to lose the contest, as long as it’s not by more than the posted number.
Power Ratings – Part of a handicapper’s process. Creating power ratings is how handicappers originate their numbers.
Prop Bet – Side bets that can be made in addition to a standard point spread or over/under bet, such as a player’s point total.
Puck Line – Hockey’s version of the point spread. When betting on the puck line, the favorite is always -1.5 on the spread, with the underdog at +1.5. Betting on the favorite requires your team to win its game by two or more goals. Conversely, betting on the underdog at +1.5 means that your team can lose by one goal, and your ticket will still cash.
Push – Your wager ended in a tie. If you bet on a 7-point favorite and they won the game by seven, you’re getting your initial wager back. If you bet on the game going over 40 points and it finished 23-17, you’re getting your initial wager back.
Reverse Line Movement – When the majority of money is wagered on Team A, but the point spread moves in favor of Team B. Reverse line movement can be an indicator that sharp money prefers a particular side in a matchup.
ROI (Return on Investment) – A measurement of a bettor’s performance by calculating their net profit versus the cost associated with their wagers.
Round Robin – A series of concurrent parlays on the same ticket. By structuring your parlays in a round-robin format, the bettor can lose one (or more) legs and still be profitable, depending on the ticket.
Run Line – Baseball’s version of the point spread. When betting on the run line, the favorite is always -1.5 on the spread, with the underdog at +1.5.

Teaser – A teaser is a special kind of parlay where the bettor gets assistance on the point spread for a decreased payout. The most common football teaser is a 6-point, two-team teaser.
