The odds for a game are based on a $1 per 1 moneyline point. On a Vegas odds scoreboard, the moneyline odds are usually to the furthest right. A minus ('-') before the number indicates that the team is a favorite, whereas a plus ('+') indicates that the team is an underdog. But some offer a wider range of options, like 2, 2.25, 2.75, 3, 3.75 and so on, that are a bit harder to understand and that confuses a lot a people. Total Goal Over 2 You win the bet if more than 2 goals are scored and lose it if only 1 or none goal is scored.

If the odds on a tennis player said +150, that means that for a $100 bet, you would win $150. Now if there is a minus sign in front of the odds, that is the number that you would have to bet in. Understanding American Odds As the name suggests, American odds are most popular in the United States. Working differently for favorites and underdogs, they're also known as 'moneyline' odds. American odds for betting on the favorite work by showing how much money you would have to bet in order to win $100. Welcome to the Sports Betting Odds section of The Sports Geek. If you are new to sports betting and don’t understand how to read betting odds (+150, -110, +2200, etc) we will lay it all out for you and help you learn how the betting odds work.

Have you ever wondered what the different Goal Lines mean?

You can bet on Over/Under 2.5, or Over/Under 2,25 or Over/Under 2. But what are Over 2.5 bets, or even 2.25? There are no half goals! Or quarter goals! It doesn’t seem to make sense. Does it?

We will explain what the different Goal Lines signify and after you’ve finished the article you will never be confused again!

Betting on .5 Goals

One of the most common bet types is Over/ Under .5 goals.

Obviously, there is no way for half a goal to be scored in a game. The expression .5 is just an aid to ensure that it is clear on what you are betting.

Understanding Over Under Odds

For example, if you place a bet on Over/Under 2.5 goals, then the .5 is the ‘turning point’. You win if there are at least 3 goals scored, and you lose if the match ends with less than 2 goals scored.

Here’s an example…

If you still have difficulties understanding the concept, here’s another article on the .5 bet: A Brief Introduction to Over Under Goals Betting.

Betting on Goal Lines with Whole Numbers

Bets on whole numbers are often called Goal Lines or Asian Goal Lines. Although, technically, this isn’t correct as all bets described here are ‘goal lines’, but we will be using the term as it’s widely used by punters and bookmakers.

They are somewhat similar to Asian Handicap betting on the 1×2 result. As the name suggests, the possibility of a refund exists if a certain result comes in, in this case the ‘Goal Line’.

Similar to the AH, if the match finishes in a draw result (= ‘goal line’), it’s a “push”. The punter gets their money back. Otherwise, if there are less goals scored than the goal line, the stake is lost, and if more goals are scored, it is a win.

In the above example, if you were to bet on Over 2 Goals then you get your stake back (push) if the final score is exactly 2 goals (e.g. 2-0, 1-1, 0-2).

All the other Goal Lines naturally follow the same pattern.

Betting on .75 Goals or .25 Goals – or – Whole Number, .75 or .25

If the .5 bets are combined with Asian Goal Line bets, then you get .75 or .25 Goals bets. Half of your stake is placed on the .5 bet whilst the other half is placed on the Asian Goal Line bet.

These bets are often shown as either Over 2.25 – or – Over 2, 2.5.

For example, if you place a bet of £20 on Over 2, 2.5 it means that you are placing a split bet. £10 on the 2 Goals Asian Goal Line, and £10 on Over 2.5 Goals.

If the match finishes…

  • with 3 or more goals, then you will receive the winnings of both bets
  • with exactly 2 goals, half of the stake will be returned as it was a push (2 Goals Asian Goal Line), and you will lose the other half (Over 2.5 bet)
  • with less than 2 goals… your entire stake is lost

The same applies to the .75 bets, as shown below:

In this example you place a £20 bet on the Over 2.5, 3 goal line. Again, you would be placing a split bet. £10 on the 3 Goals Asian Goal Line and £10 on Over 2.5 Goals.

If this match finishes…

  • with 4 or more goals, you will receive the winnings of both bets
  • with exactly 3 goals, half of the stake will be returned as it was a push (3 Goals Asian Goal Line), but you will win the other half (Over 2.5 bet)
  • with 2 or less goals… your entire stake is lost


Explanation Of Over Under Odds

To be honest, I would recommend keeping your hands away from these bets, although it may sound tempting to get half of the stake back. Although these are referred to as being a single bet they are actually two completely different bets rolled into one!

Betting Term Take The Over

If you do not really understand odds calculation and probabilities, then it is definitely a bet which bookmakers love! They can adjust the pricing as they like, without the average punter fully understanding the maths behind it, ensuring that the mathematical advantage lies with the bookmaker.

Anyway, the silver lining is that it is quite unlikely to be exposed to the temptation as these bets are rarely offered by European bookmakers.

Here is another diagram to demonstrating split bets:

Betting for Profit on Goals

At the end of the day the goal of each punter should be betting for profit. Am I right?

Bookmakers make a living from betting by using maths. They analyse and calculate the chances of an outcome and then price their bets. Of course, they make sure that the mathematical advantage is on their side, just like anyone operating a game of chance (e.g. Casinos).

The punter who relies only on gut feeling does not have a chance against the bookmakers.

However, with Over/Under Goal bets the punter at least has a chance to start understanding the statistics behind the bet. It isn’t too difficult to calculate the probabilities of the various results and number of goals in a game and to then find value bets.

If you are interested in starting to bet for profit, then you should seriously consider buying our Fundamentals of Sports Betting course. For the first volume, we have chosen to write about the Over/Under goal market as this is the easiest betting market to teach the fundamentals of statistics and maths on, without the need to dive deeper into more advanced formulas and concepts. Give it a try!


Understanding Over Under Odds

A totals bet is a wager where you will predict that an occurrence will be over or under a certain threshold. You can probably guess why they are called over/unders now. For example, you could bet on the over/under total points score in a basketball game.

Back Again with another 'Back 2 School' favorite celebrating 30 Years of America's Game here's another WOF Theme from 1975-1983 The Brand New Season of Wheel. Wheel of Fortune - Theme from 1989 to 1992 (extended version) in very high quality. Here is the original theme tune to the British Version of Wheel Of Fortune, composed by David Pringle and Bob Heatlie.This is the first version of the theme. Wheel of fortune theme song 1989.

Explain Over Under Odds

The bet might be over/under 165. If the total number of points scored by BOTH teams is over 165, the over bet wins. If the total is under 165, the under wins. Usually, the points will be in half points to prevent ties (Over/Under 165.5)

As you can see, this allows you to cheer for both teams to score a ton or for both teams to do terribly. Most sports games will allow you to bet on the over/under of how many points/goals/runs are scored. Some sports will also allow you to bet on the over/unders of other occurrences.

Understanding Over Under Bets

For example, golf betting sites will allow you to bet on how many birdies or how many eagles there will be on a particular hole or during a particular tournament round. Other sports may allow you to bet on how many fouls, penalties, or yellow cards there are during a game. Basically, anything that can be counted during a game or match is a candidate for a totals bet and is probably offered somewhere.
