A-Z Glossary Entries
A
- Accumulator: An accumulator, often referred to as an “acca,” is a single bet that links together two or more individual wagers and is dependent on all of those wagers winning together. The main advantage of an accumulator is that it can significantly increase the payout for a bet since the odds of each selection are multiplied together.
Example: Imagine you decide to place an accumulator bet involving three basketball games happening on the same day:
-The Lakers to win against the Celtics.
-The Bulls to win against the Knicks.
-The Heat to win against the Mavericks.
For your accumulator bet to win, you need the Lakers, Bulls, and Heat all to win their respective games. If even one of these teams loses or draws, your entire bet is lost. However, if all three teams win as you’ve predicted, your payout is significantly higher because the odds for each game are multiplied together to calculate the total odds for the accumulator.
- Against the Spread (ATS): Betting “against the spread” means you are betting on a team to either win by more than the point spread if they are the favorite, or lose by fewer points than the spread or win outright if they are the underdog. So, betting against the spread takes into account not just who wins but by how much they win or lose by, according to the spread set by the sportsbook.
B
- Bankroll: In sports betting, a “bankroll” refers to the total amount of money that a bettor has set aside specifically for placing bets. It represents the fund from which bets are made and is a critical aspect of effective money management in gambling.
- Bookmaker (Bookie): A bookmaker, often referred to as a “bookie,” is an individual or organization that accepts and pays off bets on sporting and other events at agreed-upon odds. Bookmakers play a crucial role in the betting world by setting odds for various outcomes, taking bets, and handling payouts to winners.
C
- Cover: When a team covers the spread, it exceeds the expectations set by the odds makers, resulting in a win for bettors who backed them against the spread.
- Chalk: In sports betting, “chalk” refers to the team or competitor that is considered the favorite to win, often by a significant margin. The term comes from the days when bookmakers used chalkboards to update odds and favorites frequently were written in chalk.
D
- Daily Double: A bet that involves picking the winners of two specific races on the same day, typically the first two or the last two. This term is most commonly used in horse racing.
- Decimal Odds: A way of displaying odds that represents the total payout (stake plus winnings) as a decimal number.
Example: If the decimal odds are 3.00 and you bet $100, you would receive $300 in total (your $100 stake plus $200 in winnings) if you win.
E
- Early Cash Out: A feature offered by some bookmakers that allows bettors to settle a bet before the event has concluded. This can be used to lock in profits or minimize losses.
- Even Money: A bet where the potential winnings equal the original stake. It’s often represented as 2.00 in decimal odds, +100 in American odds, or 1/1 in fractional odds.
- Exposure: The amount of money a sportsbook potentially stands to lose on a game or event. For bettors, it refers to the amount of money they risk on a particular bet or across several bets.
F
- Fixed Odds: A type of betting where the payout is agreed upon at the time the bet is placed. The odds do not change regardless of how much money is wagered on the event afterward.
- Fractional Odds: Fractional odds represent the potential profit relative to the stake, shown as a fraction. If you see odds like 5/1, it means you would win $5 for every $1 staked, not including your original stake returned. Conversely, 1/5 means you win $1 for every $5 staked.
- Futures Bet: A bet placed on the outcome of an event that will take place in the distant future, such as the winner of the next Super Bowl or World Series. These bets are usually placed before the season starts and offer higher payouts due to the increased risk.
Example: Imagine you bet $100 on the Chicago Bulls to win the NBA Championship at the start of the season. The odds given are +700. This means if the Bulls win the championship, you’ll win $700 on top of getting your original $100 back, totaling $800. If the Bulls don’t win, you lose your $100 bet.
G
- Graded Bet: A bet that has been settled and the outcome is final, determining whether it’s a win, loss, or push.
- Gambler’s Fallacy: The incorrect belief that the outcome of a random event is influenced by previous outcomes. For example, believing that a coin flip is more likely to land on heads if it has landed on tails multiple times in a row.
H
- Handicapper: A person who studies sports events and makes predictions on the outcomes, often providing tips or advice on bets to others. A good handicapper takes into account all possible factors that could affect the game.
- Home Advantage: The perceived benefit a team gains when playing in their own stadium or arena, due to factors like familiarity with the venue, support from local fans, and the absence of travel fatigue.
I
- In-Play Betting: Also known as live betting, this is the act of placing bets on an event after it has started and before it ends. Odds fluctuate in real-time based on the action unfolding in the game.
K
- Key Numbers: In sports betting, especially football, key numbers refer to the most common margins of victory or final score differences. The most common key numbers are 3 and 7, reflecting the scoring system of football through field goals and touchdowns.
L
- Limit: The maximum bet taken by a bookmaker on a particular event. Limits can vary based on the sport, type of bet, and the bookmaker.
- Live Betting: Also known as in-play betting, this allows bettors to place bets on sporting events as they are happening. Odds change in real-time based on the action taking place.
M
- Margin: The margin is the difference between the actual betting line and the break-even point for the sportsbook. It’s also another term for the bookmaker’s commission or “vig.”
- Martingale System: A betting strategy where a bettor doubles the bet amount after each loss, aiming to recover previous losses and gain a profit with the first win. It requires a significant bankroll and carries high risk.
N
- Net Winnings: The total amount of money a bettor wins after deducting the original stake from the payout. This is the profit made from a bet.
O
- Over/Under: A bet on whether the total score or points in a game will be over or under a predetermined number set by the bookmaker.
Example: Let’s say there’s a basketball game between the Lakers and the Celtics. The sportsbook sets the Over/Under line for the total points scored by both teams at 200.5 points.
Over 200.5 Points: If you believe the Lakers and Celtics will combine to score at least 201 points, you would bet on the Over. For example, if you place a $100 bet on the Over and the total score is 201 points or more, you win the bet according to the specific odds the sportsbook offers (usually around -110, meaning you would win about $90.91, plus your original $100 stake back).
Under 200.5 Points: If you think the teams will score 200 points or fewer combined, you bet on the Under. If you bet $100 on the Under and the total score is 200 points or fewer, you win the bet at similar odds to the Over bet, netting you around $90.91 in winnings, plus your original $100 stake.
P
- Parlay: A single bet that links together two or more individual wagers for a high payout. All the bets included in the parlay must win for the bettor to win the parlay. If any of the bets lose, the entire parlay loses.
- Proposition Bet (Prop Bet): A wager on a specific occurrence or non-occurrence within a game or event that does not directly affect the game’s final outcome. Examples include betting on the first team to score, the number of strikeouts a pitcher will record, or the length of the national anthem.
- Payout: The amount of money a bettor receives from a winning wager, including the initial stake and the winnings.
Q
- Qualifier / Qualifying Bet: A bet that qualifies for something specific, such as a promotion, bonus, or a next stage in a betting competition. The criteria for what constitutes a qualifying bet can vary widely depending on the bookmaker’s rules or the specific promotion’s terms.
R
- Rollover: A requirement set by online betting sites that a bettor must meet before being allowed to withdraw a bonus amount. It typically involves wagering a specified amount of money, often multiple times the value of the initial deposit plus the bonus.
S
- Spread Betting: A type of betting that depends on the accuracy of the wager rather than a simple win or lose outcome. The spread refers to a scoring range set by the bookmaker to level the playing field between two unevenly matched teams. Bettors decide if the outcome will be above or below this spread.
- Stake: The amount of money placed on a bet. The stake represents the bettor’s investment in the outcome of an event, with potential returns calculated based on this amount and the odds provided.
T
- Teaser: A type of parlay bet where the bettor is allowed to adjust the point spread or total for a game in exchange for reduced odds. The adjustment makes it easier to win the bets, but the payout is less than a standard parlay.
- Totals Bet: Also known as an over/under bet, it involves betting on whether the combined score of both teams in a game will be over or under a specified number set by the bookmaker.
U
- Underdog: The team or competitor considered less likely to win a game or event. Betting on the underdog offers higher potential payouts due to the perceived risk of the bet.
V
- Value Bet: A bet that is believed to offer a greater return than its odds suggest, providing what the bettor perceives as “value.” This occurs when a bettor believes the chances of a particular outcome are higher than what the odds offered by the bookmaker reflect.
W
- Wager: Another term for a bet. It refers to the act of risking money on the outcome of the game or event you are betting on.
- Win Bet: A straightforward bet where the bettor picks a competitor or team to win a particular event outright. It’s one of the most common types of sports bets.
Z
- Zig-Zag Theory: This is a betting strategy used primarily in playoff games for sports like basketball and hockey. The theory suggests that in a series, teams are more likely to perform better following a loss, especially when playing at home.
