Betting Glossary A To Z

I travel to Las Vegas every year for the Super Bowl. I overhear many conversations near the betting boards in the sportsbooks on the Strip, and most of them center around gambling terms.

Most bettors don’t know what all the numbers mean on the odds board. They’re confused about how to make a bet. These gaming words are made clear on most top-ranked online sites like Bovada and BetNow, but Las Vegas sportsbooks do a poor job in explaining gaming terminology.

Here, VegasBetting explains the gambling lingo from A to Z that will help you become an informed Vegas gambler on all the action in any sportsbook.

Glossary A to Z


An accumulator is a wager that combines four or more picks into a single bet that earns a return only when all picks win. The advantage of an “accumulator” is that winnings are much higher but they come with an increased risk — just one wrong pick loses the entire bet.

Added Game

If there is enough betting demand for action on a game, sportsbooks may choose to list odds for the matchup and start taking bets on it. The new listing is the definition of an “added game.”


AET stands for “Added Extra Time.” The term is commonly used in soccer matches where time is added for stoppages and injuries.

Alternative Lines

Alternate lines cover both sides of the betting line, allowing users to bet under or over the original betting line and this bet always adds more risk to the wager. Alternate lines are most often offered on the spread and over/under point totals, and typically posted on MLB and NHL games.

American Odds

Betting lines are posted on a 100-unit base figure in American Odds. Whenever there is a negative (-) sign, that’s the amount of money a bettor must wager to win a hundred dollars. Whenever there is a positive (+) sign, that’s the amount a bettor wins on a hundred dollar wager.


Ante-post betting, also known as futures betting, are wagers where the result is determined at a later date. For example, an ante-post bet can be placed on the winner of the Super Bowl during the regular season.


Arb or arbitrage betting is a risk-free wager to make a guaranteed profit on a particular sporting event. When arbing, the bettor takes advantage of the difference in odds offered by two or more bookmakers. An arb is also sometimes called a “surebet” or a “miraclebet.”


Arbitrage is a betting system that allows a customer to place multiple bets to guarantee a profit regardless of the outcome of the event.

Asian Handicap

Asian Handicap is a form of betting on football in which teams are handicapped according to their form so that a stronger team must win by more points than the betting line.


ATS stands for “Against The Spread” and is used to describe a wager against the betting line. Oddsmakers attempt to predict how many points (spread) it will take for approximately the same amount of money to be wagered on the favorite and underdog.



A “banker” bet is the most important selection for your combination or accumulator bets. It gives the bettor a chance to earn a profit, even if one or two of the other selections do not win. The banker bet must win for the rest of your ticket to be successful. If your banker loses, so does your ticket.

Best-Price Percentage

Bookmakers offer different prices on outcomes of events. By always choosing the best price on offer and being strict with only getting the best price, the bettor is opting for the “best-price percentage.”


A wager made on the outcome of an event. Players may be able to make several bets on a single event.

Betting Exchange

A betting site that doesn’t accept bets, but rather matches players against one another on both sides of the bet. The site takes a commission on the winning bets.

Betting Strategy

A systemic or mathematical approach to placing bets designed to generate a profit for the player over the house or bookmaker.


An incentive or reward given by bookmakers to encourage betting activity for new or existing members.


Short form for any online or land-based sportsbook that offers odds on the outcome of an event.

In any event, there is a longshot and a favorite. The participant with the lowest odds is considered the “chalk.”

Circled Game

An event where the maximum bet is capped or limited, usually due to injuries or poor weather conditions.

Closing Line

The last available betting lines before the market closes. Bettors who consistently beat the closing line increase their odds of winning wagers.


More than one selection is priced as the favorite with the exact same betting odds. A league’s top two teams with the same odds to win the championship would be called “co-favorites.”


It’s the added amount tacked onto the betting lines for the sportsbook to make a profit. It’s also called Juice, Margin, and Vigorish. The commission on most bets at Las Vegas sportsbooks is roughly 10 percent.

Correct Score

A bettor predicts both the winning team and the final score of the game. The bet is usually posted for soccer matches.


When the favorite wins by more than the posted spread or handicap. For example, an NFL team is favored in the point spread by three points but wins by a touchdown. The winning team “covered” the spread.

Decimal Odds

Often referred to as European odds, the betting lines are posted in a decimal format. A simple formula is your betting amount multiplied by the decimal odds. For example, a $100 bet on a team listed at 1.82 odds returns $182.


Slang term for a $1,000 wager: “I’m betting a dime on the championship.”


Abbreviation of the term underdog, which is rated by the betting market as the least likely to win. If a game between two teams has a prohibitive favorite, the other team can be called a huge “dog.”

Double Action

The odds on one of the teams increase or “drift” from the opening odds, usually because of injuries or suspensions of key players.

USA Hockey


A wager where the bettor attempts to pick a winner and a second- or third-place finisher. This betting option is most commonly used in greyhound and horse racing.


Betting margins are the difference between the odds the bettor is offered by sportsbooks and the true probability of the outcome. If you can exploit a bookmaker’s margin, you have gained an “edge.”

Even Money

A bet which is listed at +100 or 1-1 is considered to be “even money.” The return is exactly double your initial wager.


Any wager other than a straight bet is called an “exotic.” In horse racing, it’s any wager that is not win, place or show.

Expected Goals

The number of times a team or teams will score in a single game. For example, bettors will use this feature to help determine the over-under totals of a hockey game.

Expected Value

The measure of what a bettor can expect to win or lose per bet placed on the same odds time and time again is called “expected value.”


The total amount of money a sportsbook stands to lose from a particular event. In 2019, the exposure for New Jersey sportsbooks was $4.5 million when the Philadelphia Eagles upset the New England Patriots in Super Bowl 53.


The top pick according to the betting markets is called the “favorite.” Just because the favorite has the lowest odds does not necessarily mean it is the most likely to win.

First-Half Bet

A bet on the outcome of the first half of play in a single game.

First/Last Goal Scorer

A bet on the specific scorer of the first or the last goal in a given game, usually in soccer or hockey.

Fractional Odds

The ratio of the amount profit compared to the unit bet is called “fractional odds.” For example, a team that is listed at 6-1 would pay $6 profit for every $1 bet.


Betting lines posted for an event that is to take place at a later date. For example, “future” bets are made in the NFL preseason or regular season on which team will win the Super Bowl.

Grand Salami

A wager where the bettor selects whether the total number of goals, runs or points will be over or under a betting line. It’s also known as the totals bet.

Half-Time Bet

A bet made on the result of the first half of a specific game.

Half-Ball Handicap

One team is allotted 0.5 of a point, run or goal in a game with betting lines attached to that “handicap.”


One team, typically a prohibitive favorite, is given a “handicap” to overcome in order to win. It is similar to point spread betting and provides more balanced odds.

Holding Your Own

Home-Field Advantage

Home teams take advantage of the familiar surroundings and hometown crowd to win the majority of games, often around 55 to 60 percent, depending on the sport. That’s why it’s commonly referred to as a “home-field advantage.”


A series of bets that carry over to the next wager and are dependent on the previous selection.

In-Play Betting

Regular betting stops once the event starts, but that is when “in-play betting” begins. Also known as live betting, players can wager in real-time on the next play, score or outcome throughout the entire event.

Joint Favorite

Two selections in a field share the lowest betting odds in an event. The top two of the 32 NFL teams may be tagged with the same future odds to win the Super Bowl and they are called “joint favorite.”


A commission or “juice” is applied to every bet by the sportsbook, typically around 10 percent of the wager. That’s why two evenly matched NFL teams are both be listed at -110 on the betting lines and not even money.

Kelly Criterion

A mathematical formula that can be applied to determine the optimal sum of money that should be invested or wagered on an opportunity.

Landing on Three/Seven

A phrase used to describe the most statistically common final-score differential in the NFL since field goals are worth three points and touchdowns count for seven.

Laying the Points

The favorite must not only win the game but also beat the point spread when a bettor is “laying the points.”


Sportsbooks don’t always take on all the risk of a bet, especially ones of a large amount. They will at times reduce the liability of some wagers with another bookmaker.


The maximum bet amount, or “limit,” varies from online and land-based sportsbooks.


Also known as point spread, the betting “line” is the assigned number on the favorite and underdog to encourage betting on both sides involved in the game.

  • Treble: A multiple bet consisting of three selections, where all must win to earn a return.
