When you bet for the underdog, it is called betting 'against the odds.' For example, if odds are 3/1 for the Cowboys this Sunday, then it is three times more likely that they will lose than win. Odds of 3-1 indicate that if you bet $100, you will win $400, the original amount of your bet plus the profit.
If you place wagers on US sports, then chances are high that you’ve heard of point spreads. Here’s how they work; if a game has Patriots -9.0 and Vikings +9.0, the Patriots are 9.0 point favorites and the Vikings are 9.0 point underdogs. Unless otherwise stated, no matter which team you bet on, you’ll be required to risk $1.10 for each $1.00 you want to win. For Patriots bettors to prevail, they need their team to win by 10 or more points. A 9-point Patriot victory would be a push (a tie). For Vikings bettors to take home the victory, they need to either win the game or lose by less than 9 points.
Point spreads are used since most recreational bettors prefer to wager even money propositions. In the above example, if there was no point spread, only moneyline betting would exist. So, if odds makers are giving the New England Patriots a 73% chance of winning a game, then in order to take bets and still have a small profit margin, the bookmaker would have no choice but to require Patriot bettors to stake $3.00 or more for each $1.00 they want to win.
With a point spread, the odds are balanced, so you usually have to risk just $1.10 to win $1.00. This makes the point spreads appealing to recreational bettors, who often think it’s easy to make money from them. We have to be honest with you; it’s NOT easy, but it IS possible. The strategy we cover in this article should help!

Simple Tips for Point Spread Betting
Strategy for betting point spreads is obviously different for each sport and league, but these four tips are general enough to apply to them all.
- Take Advantage of Bonus Offers
- Use Multiple Betting Sites
- Be Careful of Road Favorites
- Understand Key Numbers
Let’s go over each of these tips in a little more detail.
Take Advantage of Bonus Offers
One way to make money from sports betting is to open an account at an online betting site and take advantage of their sign up bonus. This gives you extra money to wager with, and since point spreads are so straightforward, it can be relatively easy to meet the associated wagering requirements and still come out ahead. Repeating this process at multiple betting sites will maximize your potential returns! We just ask that you please stick with reputable sites, like any of the ones that we recommend.
Use Multiple Betting Sites
We already mentioned how using multiple betting sites allows you to take advantage of multiple bonus offers. That’s not the only benefit either. Since point spreads vary between sites, one of the best ways to beat these wagers is to compare the different spreads in order to find which one is the most favorable. This doesn’t take nearly as long as you might think, and it will make a huge difference to your bottom line over time.
Let’s take a hypothetical game between the Buffalo Bills and the New England Patriots as an example. One site might have the spread as follows.
Another site might offer a slightly different spread.
If you’re betting in favor of the Patriots, then you should be betting with Bookmaker A. If the Patriots win by more than seven points, then you’ll win with either bookmaker. However, if they win by exactly seven points, you’ll lose with Bookmaker B. With Bookmaker A, you’ll push and get your stake returned.
On the other hand, if you’re betting on the Bills, then Bookmaker B will be your best option. A Bills loss of exactly seven points would be a push at Bookmaker A, but it would be a win for you at Bookmaker B.
It’s only a half-point difference, and that might not seem like a lot. The bookmakers tend to be very accurate with their spreads though, and an extra half-point in your favor can easily add up to extra profits over time.
Be Careful of Road Favorites
Many novice bettors fail to understand the impact of home advantage when wagering on sport events. When looking at the board for potential wagers, these bettors tend to get excited and bet on lots of superior teams favored on the road against weaker opponents. The betting market is so much more advanced than this, and for the most part point spreads are always going to be 50/50 propositions.
Please NoteWe’re not saying that you should never bet on road favorites. Just make sure that you have good reasons to do so. Keep in mind; they don’t just need to win, they need to win by a greater margin than the spread suggests they will.
Understand Key Numbers
While understanding key numbers is beneficial for betting point spreads on any sport, key numbers are known for having the most significance in football. In NFL football, most games are decided by three or seven points. Therefore, when shopping the odds, the difference between -7.0 and -6.5 is far greater than the difference between -5.5 and -5.0.
With some betting sites odds, certain games are priced differently than risking $1.10 to win $1.00 (which is called -110 odds). For example, you might see the Giants priced at -105 and +7 in a game against the Jets. Now, you only have to risk $1.05 to win $1.00. This is obviously better odds, but it’s very likely that they will lose by exactly seven to give you a push. Taking -110 and +7.5 with an alternative bookmaker is actually the better bet.
Getting your head around these kind of intricacies, as well as knowing the relevant key numbers, is vital if you want to bet on the point spreads successfully.
Now that we’ve got the basic tips covered, we want to provide you with some point spread betting tips specific to two of the most popular US sports: football and basketball.
Point Spread Betting in Football
One of the best ways to beat football point spread betting is to use teasers. A teaser is a form of a parlay bet using modified point spreads. Each point spread you select is moved 6 points in your favor. For example, let’s say you’re interested in betting on the following.
A teaser would give you a single wager with the following spreads.
Each selection is obviously easier to get right with the spread moved in your favor, but you do have to get all three correct in order for your wager to win.

Another way to beat football point spreads is to shop for off market prices. For example, let’s say you’re shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that’s offering +7.5. There’s a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn’t quite the same as simply shopping for the best lines. Here, you’re specifically looking for wagers that are +EV because they’re against the market.
It’s also important to consider whether or not there’s any correlation between the point spread and the betting total. If they are, a parlay wager is a good way to get maximum value. For example, a college football point spread +24.5 parlayed with under 48 points in the same game might be a great parlay bet. If the +24.5 team covers the point spread, then there’s an increased chance that the game also goes under the posted total of 48.
Finally, you might want to think about learning the correct strategies for buying half-points in football. While many people are against this method, we’re here to tell you that there are some circumstances where buying points can be profitable.
Point Spread Betting in Basketball
Buying half points is a strategy that can work for basketball too. Most online betting sites offer bettors the ability to purchase half-points at 10 cents each. Let’s say the Lakers are -6.5 at odds of -110 for example. Here of some of the options you can expect to see.
Spread Gambling Meaning
A great strategy for betting basketball point spreads is to shop dozens of betting sites for the best line, and then purchase as many half points as possible (provided they are priced 10 cents each).
When using this strategy, it’s helpful to know the most common margins of victory in NBA basketball and how often they occur.
This information shows us that nearly half the games finish with one of the eight point margins listed, and this isn’t the result of variance. Some margins of victory occur more frequently than others because of end game strategy. The winning team is often found running the clock, while the losing team if often found intentionally fouling.
The key here is to target the point spread five and seven, because these are virtually tied as the most common margins of victory. It’s important to recognize that most betting sites are only willing to sell 2 or 3 half points for 10 cents each, after which point they start charging more. Some sites sell up to four half points at this price though.
To show how this can be exploited, take a point spread of -8.5 at odds of -110. This is a 50/50 proposition. Let’s assume you’ve purchased enough points to move the spread to -6.5 at odds of -150. Now, you’d win instead of lose 6.24% of the time they win by 8, and 6.59% of the time they win by 7. Add these together with the 50% from the original proposition, and we get 62.83%.
Go to our odds converter, and you’ll see that the implied probability of -150 is 60%. This means you need to win 60% of the time to break even. However, our handicapping shows the actual probability of winning is 62.38%.
If we risked $150 to win $100 on this -150 line, 62.38% of the time we would win $100. And 37.62% of the time we would lose $150. This gives us an expected profit of $5.95 for every $150 risked.
WarningIf you only make large +EV bets such as the basketball example above, betting sites will limit the amount you’re allowed to wager. It’s not uncommon for online bookmakers to spot a skilled bettor and say, “Okay you can keep wagering here, but the maximum you’re allowed to bet per game is $500.00.”
If you keep betting and winning, they might decrease your limits even further. That’s why we recommend trying to hide the fact that you’re so sharp. By placing some random wagers and occasionally spending some time at their casino, you’ll have a much better chance of staying under the radar.
This is also another good reason for using multiple sites. Since there are so many different reputable betting sites to choose from, it would take you a long time to get limited at every single one of them.
Fixed-odds betting is a form of wagering against odds offered by a bookmaker or an individual or on a bet exchange. It involves betting on an event in which there is no fluctuation on the payout. In Australia, the practice is usually known as 'SP betting'.
Calculating fixed odds[edit]
It is customary with fixed-odds gambling to know the odds at the time of the placement of the wager (the 'live price'), but the category also includes wagers whose price is determined only when the race or game starts (the 'starting prices'). It is ideal for bookmakers to price/mark up a book such that the net outcome will always be in their favour: the sum of the probabilities quoted for all possible outcomes will be in excess of 100%. The excess over 100% (or overround) represents profit to the bookmaker in the event of a balanced/even book. In the more usual case of an imbalanced book, the bookmaker may have to pay out more winnings than what is staked or may earn more than mathematically expected. An imbalanced book may arise since there is no way for a bookmaker to know the true probabilities for the outcome of competitions left to human effort or to predict the bets that will be attracted from others by fixed odds compiled on the basis personal view and knowledge.
With the advent of Internet and bet exchange betting, the possibility of fixed-odds arbitrage actions and Dutch books against bookmakers and exchanges has expanded significantly. Betting exchanges in particular act like a stock exchange, allowing the odds to be set in the course of trading between individual bettors, usually leading to quoted odds that are reasonably close to the 'true odds.'
'The best of it'[edit]
In making a bet where the expected value is positive, one is said to be getting 'the best of it'. For example, if one were to bet $1 at 10 to 1 odds (one could win $10) on the outcome of a coin flip, one would be getting 'the best of it' and should always make the bet (assuming a rational and risk-neutral attitude with linear utility curves and have no preferences implying loss aversion or the like). However, if someone offered odds of 10 to 1 that a card chosen at random from a regular 52 card deck would be the ace of spades, one would be getting 'the worst of it' because the chance is only 1 in 52 that the ace will be chosen.
In an entry for L'Encyclopédie (the Enlightenment-era 'French Encyclopedia'), Denis Diderot cites a similar example in which two players, Player A and Player B, wager over a game of dice that involves rolling two six-sided dice. Player A wins if the dice add up to 12, of which there is only one possible case. Player B wins if the dice fall in any other combination, of which there are 35 possibilities.[1] It is mathematically disadvantageous to make a bet if one gets'the worst of it.' Accordingly, for the bet to be 'fair,' the amount each player could potentially lose or gain from the wager should be adjusted, depending on the odds of their success.
Laying odds[edit]
When making a bet in which one must put more at risk than one can win, one is laying the odds. Rational bettors will do so only if the actual chances of an adverse outcome are low enough that the expected outcome even after deduction of taxes and any transaction costs is favorable to the person placing the bet. For example, if one bets $1,000 that it will rain tomorrow and can win only $200 but can lose the entire $1,000, one is laying odds that will rain tomorrow. Laying odds is reflected in the colloquial expression '[I would] dollars to doughnuts' — with which the speaker is expressing a willingness to risk losing something of value in exchange for something worthless, because winning that bet is a certainty.[2]
Lay betting[edit]
'Lay betting' is a bet that something will not happen, so 'laying $50 on a horse' is betting the horse will not win. Bookmakers sell bets based on the odds of a specific outcome, but lay betting allows the bettor (in some English-speaking countries, the 'punter') to reverse roles with the bookmaker, using odds to sell the opposite outcome to the bookmaker. In this context, 'lay' is used in the sense of 'layman', i.e., a bet sold by someone who does not sell bets professionally.
Types of odds offered[edit]
There are three widely used means of quoting odds:
Fractional odds[edit]
Favoured by bookmakers in the United Kingdom and Ireland and common in horse racing, fractional odds quote the net total that will be paid out to the winning bettor relative to the stake. The term 'fractional odds' is something of a misnomer, especially when visually reinforced by using a slash (as opposed to, e.g., a colon or the word 'to' or 'on') to separate a potential gain from the amount that a bettor must wager in order to receive it upon a win, because the 'fraction' in question represents not the odds of winning or even the reciprocal of the odds of winning but rather the fraction (for any odds longer than 'even money' or chances of winning less than 50%, an improper fraction) of the amount at stake that the upside outcome represents. This fraction may be derived by subtracting 1 from the reciprocal of the chances of winning; for any odds longer than 'even money,' this fraction will be an improper one.[3][4] Odds of 4:1 ('four-to-one' or less commonly 'four-to-one against') would imply that the bettor stands to make a £400 profit on a £100 stake. If the odds are 1:4 (read 'one-to-four', or alternatively 'four-to-one on' or 'four-to-one in favor'), the bettor stands to make £25 on a £100 stake. In either case, against or on, should he win, the bettor always receives his original stake back, so if the odds are 4:1 the bettor receives a total of £500 (£400 plus the original £100). Odds of 1/1 are known as evens or even money.
Not all fractional odds are traditionally read using the lowest common denominator. Perhaps most unusual is that odds of 10:3 are read as 'one-hundred-to-thirty'.
Fractional odds are also known as British odds,UK odds,[5] or, in that country, traditional odds.

Decimal odds[edit]
Favoured in Continental Europe, Australia, New Zealand and Canada, decimal odds differ from fractional odds by taking into account that the bettor must first part with their stake to make a bet; the figure quoted, therefore, is the winning amount that would be paid out to the bettor.[4][6] Therefore, the decimal odds of an outcome are equivalent to one plus the decimal value of the fractional odds; in the absence of built-in house advantage to cover overhead, profit margins, or (for an illegal enterprise) compensation for the fact that both chances of prosecution and penalties in the event of conviction tend to be higher for bookmakers than for clients, the decimal odds associated with a given outcome would be the decimal expression of the reciprocal of what the offering party assesses to be the outcome's chance of occurring.[7] Thus, even odds 1/1 are quoted in decimal odds as 2. The 4/1 fractional odds discussed above are quoted as 5, while the 1/4 odds are quoted as 1.25. It is considered to be ideal for parlay betting because the odds to be paid out are simply the product of the odds for each outcome wagered on.
Decimal odds are also known as European odds, digital odds or continental odds and tend to be favoured by betting exchanges because they are the easiest to work with for trading, in this case the purchase and sale of upside and downside risk.[5]
Moneyline odds[edit]
Moneyline odds are favoured by United States bookmakers and as such are sometimes called American Odds.[4] There are two possibilities: the figure quote can be either positive or negative. Moneyline refers to odds on the straight-up outcome of a game with no consideration to a point spread.
- Positive figures
- If the figure quoted is positive, the odds are quoting how much money will be won on a $100 wager (done if the odds are better than even). Fractional odds of 4/1 would be quoted as +400 while fractional odds of 1/4 cannot be quoted as a positive figure.
- Negative figures
- If the figure quoted is negative, the moneyline odds are quoting how much money must be wagered to win $100 (this is done if the odds are worse than even). Fractional odds of 1/4 would be quoted as −400 while fractional odds of 4/1 cannot be quoted as a negative figure.
- Even odds
- Even odds are quoted as +100 or −100. Some but not all bookmakers display the positive symbol.
Odds conversion[edit]
Free Gambling Sites
To convert fractional odds to decimal, take the fractional number, convert it to decimal by doing the division, and then add 1. For example, the 4-to-1 fractional odds shown above is the same as 5 in decimal odds, while 1-to-4 would be quoted as 1.25.
The method for converting moneyline to decimal odds depends on whether the moneyline value is positive or negative. If the moneyline is positive, it is divided by 100 and add 1. Thus, +400 moneyline is the same as 5.0 in decimal odds. If the moneyline is negative, 100 is divided by the absolute moneyline amount (the minus signed is removed), and then 1 is added. For example, −400 moneyline is 100/400 + 1, or 1.25, in decimal odds.
Decimal | Fractional | Moneyline | Win% (to break even) | Return (minus stake) |
---|---|---|---|---|
1.01 | 1/100 | −10,000 | 99.01% | 1.00% |
1.11 | 1/9 | −900 | 90.00% | 11.11% |
1.33 | 1/3 | −300 | 75.00% | 33.33% |
1.50 | 1/2 | −200 | 66.67% | 50.00% |
2.00 | 1/1 | ±100 | 50.00% | 100.00% |
3.00 | 2/1 | +200 | 33.33% | 200.00% |
4.00 | 3/1 | +300 | 25.00% | 300.00% |
10.00 | 9/1 | +900 | 10.00% | 900.00% |
101.00 | 100/1 | +10,000 | 0.99% | 10,000.00% |
