Sports Betting Glossary for Betting Types

Asian Handicap

Ah! The Asian Handicap meaning. This is a bet where you move the odds in favor of the underdog, essentially giving them a head start and handicapping the favorite. Simple right? Well there’s a little more to this betting type, as it can be split into three variations, known as full, half and quarter handicap:

  • Full Handicap (+1, -1, etc.): Simple! If you bet on a team with a -1 handicap, they need to win by more than one goal for you to win. If they win by exactly one, it’s a tie (push). If you bet on the +1 team, they just need to avoid losing by more than one goal.
  • Half Handicap (+0.5, -1.5, etc.): No ties here! A -0.5 handicap means your team needs to win outright. A +0.5 handicap means your team wins if they win or draw.
  • Quarter Handicap (+0.25, -0.75, etc.): Double the fun! Your bet is split in two. With a -0.25, half your bet is on -0.5 and half on 0. If your team draws, you lose half and get a refund on the other half. With a +0.25, half is on 0 and half on +0.5, so you can win half and push half if the game draws.

Betting Exchanges

A betting exchange, explained in simple terms, is like a marketplace where you can bet against other players instead of a bookmaker. Betting exchanges effectively let you be the house, set your odds, and offer odds on anything, from football to reality TV! It's peer-to-peer betting, adding extra excitement and strategy to the mix.

Fixed Odds

The meaning of fixed odds is knowing exactly what you’ll win right when you place your bet. Basically, the moment your wager is accepted at a sportsbook, the odds are locked in, so no matter what happens from that point on, you’ll know exactly where you stand. No surprises, just straightforward betting!

Hedge Betting

Hedge betting is like having a safety net when you are placing your bets. It’s all about minimizing any risks and guaranteeing profits by placing a second bet to cover the opposite outcome. For example, you bet $100 on Inter Miami to win the MLS at +1000 odds at the beginning of the season. As the end of the season approaches both Inter Miami and Cincinnati are the two main contenders who can win the league. So, you place a hedge bet of $200 on Cincinnati to win the league at -200 odds. If Inter Miami wins the league you get $1000 from your original bet. If Cincinnati wins, your hedge bet returns $300. Either way you’ve made a profit.

10 Must Know Betting Terms to Get Started

Now that you’ve got an idea of the different types of betting terms, it’s time to hone in on the must know terms in more detail.

Below are 10 of the most common betting terms you’ll see at most sportsbooks.

1️⃣ Accumulator

Also called an ‘acca’ or ‘parlay’ in the US, this is a bet that combines multiple selections into one bet. In order to get a payout, every leg of the bet must win, which means the potential profit is increased, but so is the risk.

Example: You place a $10 four-leg accumulator on these Premier League matches:

  • Manchester City to beat Everton at 1.40
  • Arsenal to beat Wolves at 1.50
  • Chelsea to beat West Ham at 1.80
  • Liverpool to beat Aston Villa at 1.60

Individually, these bets would be quite modest, however when you combine them, the odds are 6.048, and the returns are increased - i.e $10 x 1.4 x 1.5 x 1.8 x 1.6 = $60.48. If all legs of your accumulator win, your winnings would be $60.48 - $10 stake = $50.48. If one or more legs lose though, you win nothing.

2️⃣ Odds

Odds are an indicator of how likely the outcome of a game is, and also how much you can win relative to your stake. They’re displayed in different formats depending on the sportsbook.

Example: American odds (+150 / -200), fractional odds (5/2), or decimal odds (3.50).

3️⃣ Moneyline

Moneyline is the simplest type of bet - you are picking who will win the game. Points, score or margins are not required. Odds are shown as positive or negative numbers.

Example: You want to bet on the NFL Lions vs Ravens. Lions are +200 and Ravens are -180. The - symbol means the Ravens are favorites, so you'd need to bet $180 to win $100 on them. The + sign means the Lions are the long shot, so a $100 bet could net you $200 if they grab the win.

4️⃣ Spread

The spread (also known as point spread) helps equal out the bets, by giving the underdog extra points and the favorite a handicap. This type of bet is popular in football and basketball.

Example: If the Lakers are -6 against the Knicks, they must win by 6 points or more for a payout. If the Knicks lose by fewer than 7 or win outright, the bet comes in.

5️⃣ Over/Under

Also known as totals betting, over/under focuses on how many combined points, goals, or runs will be scored in a game. It’s a great option if you want to place a bet but don’t want to pick a side.

Example: A bet of ‘over’ 2.5 goals in soccer means you expect 3 or more goals, or you’d select ‘under’ 2.5 goals if you expect 2 or less goals.

6️⃣ Prop Bet

A prop bet (short for proposition bet) isn’t actually about the end result, but what happens within the game. Props add variety to betting markets, especially in big events like the Super Bowl, where you even have bets on the coin toss outcome.

Example: Prop bets could be ‘Patrick Mahomes to throw 3+ touchdowns’, ‘first goal scorer’, and ‘total number of corner kicks’.

7️⃣ Futures

If you enjoy placing bets far ahead of time, futures bets could be for you. These bets usually carry longer odds when placed early and can help lock in better odds before the favorites come to light. You need to have patience though, as you could be waiting months for the result.

Example: ‘Kansas City Chiefs to win the Super Bowl’ or ‘Novak Djokovic to win Wimbledon’.

8️⃣ Live Betting

You may see this referred to as in-play betting, but effectively live betting allows you to place wagers during the game. You’ll witness odds fluctuating in real-time based on what’s happening. Live betting is fast-paced and perfect if you're open to different results and scenarios.

Example: You could bet on the Celtics to come back after falling behind early, or Mohamed Salah to score the next goal.

9️⃣ Push

A push occurs when a bet ends in a tie between the sportsbook and the bettor. It’s not a win, but it’s not a loss either, so your bet will usually be refunded. This often happens with spread or over/under bets.

Example: You bet the ‘over 42 points’ in an NFL game and it ends 22–20 (exactly 42). Your stake is refunded.

🔟 Bankroll

It may be last in our list, but it’s an important one. Your bankroll is the amount of money you’ve set aside exclusively for betting. Smart bettors will manage their bankroll carefully, and only bet a small percentage like 1–5% on each wager.

Example: If your bankroll is $500, betting $10–$20 per game helps you continue betting for longer and avoids busting your account after a few losses.

Concluding this Betting Glossary Guide

Well, with all of these important betting terms explained, it’s time to wrap things up. I hope this betting school guide has been both insightful and useful. Giving you all of the tools you need to fully understand more about the terminology for different sports and the markets that you can bet on.

Betting Terms Explained FAQs

❓ What are Moneyline Odds?

Moneyline odds are a type of betting odds that show you how much you can win on a bet. There are two versions, positive odds (e.g. 150+) which indicate how much profit you can make on a $100 bet. While negative odds (e.g. -200) show how much you need to bet to win $100. The higher the positive odds the higher the potential profit, but lower the implied probability of the bet winning. The higher the negative odds the lower the potential profit, but the higher the implied probability of success.

🤔 What is Point Spread Betting?

Point spread betting refers to a wager on the margin of a victory in a game. Where the favorite gives points and the underdog receives points to even the odds.

📱 What is the Martingale System?

The Martingale System is a gambling strategy where a bettor doubles their bet after each loss aiming to eventually recover losses and make a profit. This is a very risky way to wager, but is typically used in situations where the odds are close to evens or slightly better.
