Glossary of Betting Terms
Sports Gambling Terms
Added Game: Most common in College sports, Added Games are contests that are not part of the daily selection list but rather added due to public demand. An added game may also be a previously cancelled contest – such as a rained out match from the day before in baseball.
AET: Short for “Added Extra Time” AET betting options are common in soccer matches where time is added for stoppages, injuries or two-leg Cup matches that end in a tie after regulation time in the second contest.
Alternative Lines: Common in most sports, Alternative Lines raise or lower the set match odds and prices change accordingly. As an example, a +7 (1.95) NFL line can be bet on at anywhere between +3 (2.52) to +11 (1.48) odds.
American Odds: Based on 100 unit wagers, American Odds are alternatives to Decimal and Fraction betting lines. Negative lines indicate a favorite while underdogs are tagged with plus odds. Winning wagers on a (-320) line returns a $31.25 profit while (+320) odds pays $320.
Ante-post: Posted well in advance of horse races, and pro sport championships, Ante-post odds are also known as Futures or Outright wagering options. Ante-post prices have added value but come with risks as a horse may not run or a team may not make the championship round.
ARB: Short form for Arbitrage betting below.
Arbitrage: Available when bookmakers post different odds, on the same match, Arbitrage betting is designed to set up “risk free” wagers that pay a return regardless of which side wins. If one sportsbook offers NYJ at (2.05) while another has MIA at (2.05) betting both sides sets up a guaranteed return.
Asian Handicap: A variation of spread wagering, Asian Handicap is primarily associated with soccer betting and odds run from ¼ to multiple goals. Since a draw result is not possible with Asian Handicaps, bettors choose between two sides rather than three.
ATS: Against The Spread (ATS) betting allows players to take or lay points/goals. DAL -6.0 vs WAS +6.0 means the Cowboys need to win by at least 7 points in order to cash. A Redskins wager pays if Washington wins outright or losses by 5 points or less. A 27-21 final would result in a PUSH and wagers are returned.
Banker: Associated with parlay betting, a Banker is a perceived “lock” favorite and is used as the foundation of accumulator bets with additional less obvious sides added around it.
Best-Price Percentage: Implies the chance of winning on a variety of odds. A match with EVEN (2.00) odds gives both sides a 50% chance of cashing. A price posted at (3.00) means the wager has a 33.33% chance of winning.
Bet: Real or bonus money used to wager on any betting option.
Betting Exchange: Neither a player nor the house, a betting exchange allows bettors to wager against each other rather than a bookmaker. A player wanting to bet the Patriots at -7 needs another player to take the Jets at +7 to create action. The betting exchange takes a small commission from the winning side.
Betting Strategy: Different from bettor to bettor, a betting strategy consists of one to several approaches designed to give handicappers an edge over bookmakers. Home Dogs, Sandwich Games and fading teams playing on back-to-back nights are common strategies.
Bonus: Player rewards, such as cash-back or free bets, offered to potential customers to encourage account registration and funding. Existing players are offered rewards such as reload bonuses or match free bets that can double the payout.

Co-Favorite: Common in futures betting, Co-Favorites are two or more teams priced with the same betting odds.
Commission: Also know as “juice” or “vigorish” Commission is the take of a bookmaker or the amount a betting exchange takes from winning wagers.
Correct Score: Primarily offered on Soccer, Correct Score wagering requires bettors to predict the exact final outcome and the winner of a match.
Cover: Any wager where a side exceeds the point spread. Detroit (-1.5) winning an NHL match 3-1 would be a winning wager as the Red Wings “covered” the puck line spread.
Decimal Odds: Decimal Odds are alternatives to American and Fraction betting lines. Smaller lines indicate a favorite while underdogs are tagged with larger lines. Winning wagers on (1.49) odds returns a $48.78 profit while a (2.49) price pays $149 on $100 bets.
Dime: Betting odds of (-110) are prices where the juice is 10% of the bet. Dime also refers to a $1000 wager though it can also be slang for a $10, $100 or $10000 wagers.
Dog: Short for underdog, a Dog is perceived by bookmakers to be the inferior side on any wager. The Raptors were dogs prior to the start of the 2018-19 NBA Finals vs Golden State.
Double Action: A variation of an “If Bet” Double Action is wagering on at least two different games and requires previous bets to win, tie or be cancelled to produce winning final tickets.
Double Bet: This is a wager on two separate selections with the return on the first wager rolled over to the second bet. Both selections must win to generate a return.
Double result: Wager on a single game where bettors predict the winner at halftime and fulltime. Common across most sports, a double bet example in the NFL is: NO Saints win first half/LA Rams win game.
Doubleheader: Primarily a baseball term, a doubleheader is two games, played by the same teams on the same day, with a short break in between the contests. A rained out match on Friday often creates a Saturday doubleheader.
