The goal of the casino is to set a line that encourages an equal amount of action on both sides, thereby guaranteeing a profit. This also explains how money can be made by the astute gambler. If casinos set lines to encourage an equal amount of money on both sides, it sets them based on the public perception of the team, not necessarily the real strength of the teams. Many things can affect public perception, which moves the line away from what the real line should be.
This gap between the Vegas line, the real line, and differences between other sports books betting lines and spreads is where value can be found. A teaser is a bet that alters the spread in the gambler's favor by a predetermined margin — in American football the teaser margin is often six points.
For example, if the line is 3. In return for the additional points, the payout if the gambler wins is less than even money , or the gambler must wager on more than one event and both events must win. In this way it is very similar to a parlay. At some establishments, the "reverse teaser" also exists, which alters the spread against the gambler, who gets paid at more than evens if the bet wins.
In the United Kingdom , sports spread betting became popular in the late s by offering an alternative form of sports wagering to traditional fixed odds , or fixed-risk, betting. With fixed odds betting , a gambler places a fixed-risk stake on stated fractional or decimal odds on the outcome of a sporting event that would give a known return for that outcome occurring or a known loss if that outcome doesn't occur the initial stake. The spread on offer will refer to the betting firm's prediction on the range of a final outcome for a particular occurrence in a sports event, e.
The more right the gambler is then the more they will win, but the more wrong they are then the more they can lose. The level of the gambler's profit or loss will be determined by the stake size selected for the bet, multiplied by the number of unit points above or below the gambler's bet level.
This reflects the fundamental difference between sports spread betting and fixed odds sports betting in that both the level of winnings and level of losses are not fixed and can end up being many multiples of the original stake size selected. For example, in a cricket match a sports spread betting firm may list the spread of a team's predicted runs at — If the gambler elects to buy at and the team scores runs in total, the gambler will have won 50 unit points multiplied by their initial stake.
But if the team only scores runs then the gambler will have lost 50 unit points multiplied by their initial stake. It is important to note the difference between spreads in sports wagering in the U. In the U. In the UK betting above or below the spread does not have a known final profit or loss, with these figures determined by the number of unit points the level of the final outcome ends up being either above or below the spread, multiplied by the stake chosen by the gambler. For UK spread betting firms, any final outcome that finishes in the middle of the spread will result in profits from both sides of the book as both buyers and sellers will have ended up making unit point losses.
So in the example above, if the cricket team ended up scoring runs both buyers at and sellers at would have ended up with losses of five unit points multiplied by their stake. This is a bet on the total number of points scored by both teams. Suppose team A is playing team B and the total is set at If the final score is team A 24, team B 17, the total is 41 and bettors who took the under will win.
If the final score is team A 30, team B 31, the total is 61 and bettors who took the over will win. The total is popular because it allows gamblers to bet on their overall perception of the game e. Example: In a football match the bookmaker believes that 12 or 13 corners will occur, thus the spread is set at 12— In North American sports betting many of these wagers would be classified as over-under or, more commonly today, total bets rather than spread bets.
However, these are for one side or another of a total only, and do not increase the amount won or lost as the actual moves away from the bookmaker's prediction. Many Nevada sports books allow these bets in parlays , just like team point spread bets. This makes it possible to bet, for instance, team A and the over , and be paid if both.
Such parlays usually pay off at odds of with no commission charge, just as a standard two-team parlay would. The mathematical analysis of spreads and spread betting is a large and growing subject. For example, sports that have simple 1-point scoring systems e.
By far the largest part of the official market in the UK concerns financial instruments; the leading spread-betting companies make most of their revenues from financial markets, their sports operations being much less significant. Financial spread betting in the United Kingdom closely resembles the futures and options markets, the major differences being.
Financial spread betting is a way to speculate on financial markets in the same way as trading a number of derivatives. In particular, the financial derivative Contract for difference CFD mirrors the spread bet in many ways. In fact, a number of financial derivative trading companies offer both financial spread bets and CFDs in parallel using the same trading platform.
Unlike fixed-odds betting, the amount won or lost can be unlimited as there is no single stake to limit any loss. However, it is usually possible to negotiate limits with the bookmaker:. Spread betting has moved outside the ambit of sport and financial markets that is, those dealing solely with share, bonds and derivatives , to cover a wide range of markets, such as house prices. Additionally, by avoiding the favourite-longshot bias , where the expected returns on bets placed at shorter odds exceed that of bets placed at the longer odds, and not betting with one's favorite team, but rather with the team that has been shown to be better when playing in a specific weather condition and time of day, the possibility of arriving at a positive outcome is increased.
In the UK and some other European countries the profit from spread betting is free from tax. The tax authorities of these countries designate financial spread betting as gambling and not investing, meaning it is free from capital gains tax and stamp duty , despite the fact that it is regulated as a financial product by the Financial Conduct Authority in the UK.
Most traders are also not liable for income tax unless they rely solely on their profits from financial spread betting to support themselves. The popularity of financial spread betting in the UK and some other European countries, compared to trading other speculative financial instruments such as CFDs and futures is partly due to this tax advantage.
However, this also means any losses cannot be offset against future earnings for tax calculations. Conversely, in most other countries financial spread betting income is considered taxable. For example, the Australian Tax Office issued a decision in March saying "Yes, the gains from financial spread betting are assessable income under section or section of the ITAA ". This has resulted in a much lower interest in financial spread betting in those countries.
Suppose Lloyds Bank is trading on the market at p bid, and p offer. Consider the simplest model of reducing, which uses a proportional decreasing of odds. For the above example, the following odds are in the same proportion with regard to their implied probabilities :. Examining how he potentially achieves this:. In reality, bookmakers use models of reducing that are more complicated than the model of the "ideal" situation.
Bookmaker margin in English football leagues decreased in recent years. When a punter bettor combines more than one selection in, for example, a double , treble or accumulator then the effect of the overround in the book of each selection is compounded to the detriment of the punter in terms of the financial return compared to the true odds of all of the selections winning and thus resulting in a successful bet.
To explain the concept in the most basic of situations an example consisting of a double made up of selecting the winner from each of two tennis matches will be looked at:. In Match 1 between players A and B both players are assessed to have an equal chance of winning. The situation is the same in Match 2 between players C and D.
In a fair book in each of their matches, i. However, a bookmaker would probably offer odds of for example on each of the two possible outcomes in each event each tennis match. This results in a book for each of the tennis matches of The decimal odds of a multiple bet is often calculated by multiplying the decimal odds of the individual bets, the idea being that if the events are independent then the implied probability should be the product of the implied probabilities of the individual bets.
This represents an implied probability of Thus the overround has slightly more than doubled by combining two single bets into a double. This is why bookmakers offer bets such as Lucky 15 , Lucky 31 and Lucky 63 ; offering double the odds for one winner and increasing percentage bonuses for two, three and more winners. In general, for any accumulator bet from two to i selections, the combined percentage overround of books of B 1 , B 2 , In settling winning bets either decimal odds are used or one is added to the fractional odds: this is to include the stake in the return.
The place part of each-way bets is calculated separately from the win part; the method is identical but the odds are reduced by whatever the place factor is for the particular event see Accumulator below for detailed example. All bets are taken as 'win' bets unless 'each-way' is specifically stated. Non-runners are treated as winners with fractional odds of zero decimal odds of 1. Fractions of pence in total winnings are invariably rounded down by bookmakers to the nearest penny below. Calculations below for multiple-bet wagers result in totals being shown for the separate categories e.
Each-Way multiple bets are usually settled using a default " Win to Win, Place to Place " method, meaning that the bet consists of a win accumulator and a separate place accumulator Note: a double or treble is an accumulator with 2 or 3 selections respectively. However, a more uncommon way of settling these type of bets is " Each-Way all Each-Way " known as " Equally Divided ", which must normally be requested as such on the betting slip in which the returns from one selection in the accumulator are split to form an equal-stake each-way bet on the next selection and so on until all selections have been used.
Double  . Note: " Win to Win, Place to Place " will always provide a greater return if all selections win, whereas " Each-Way all Each-Way " provides greater compensation if one selection is a loser as each of the other winners provide a greater amount of place money for subsequent selections. Treble  . Accumulator  . Note: 'All up to win' means there are insufficient participants in the event for place odds to be given e. The only 'place' therefore is first place, for which the win odds are given.
Trixie , Yankee , Canadian , Heinz , Super Heinz and Goliath form a family of bets known as full cover bets which have all possible multiples present. Examples of winning Trixie and Yankee bets have been shown above. The other named bets are calculated in a similar way by looking at all the possible combinations of selections in their multiples.
Note: A Double may be thought of as a full cover bet with only two selections. Should a selection in one of these bets not win, then the remaining winners are treated as being a wholly successful bet on the next 'family member' down. For example, only two winners out of three in a Trixie means the bet is settled as a double; only four winners out of five in a Canadian means it is settled as a Yankee ; only five winners out of eight in a Goliath means it is settled as a Canadian.
The place part of each-way bets is calculated separately using reduced place odds. Thus, an each-way Super Heinz on seven horses with three winners and a further two placed horses is settled as a win Trixie and a place Canadian. Virtually all bookmakers use computer software for ease, speed and accuracy of calculation for the settling of multiples bets. Patent , Lucky 15 , Lucky 31 , Lucky 63 and higher Lucky bets form a family of bets known as full cover bets with singles which have all possible multiples present together with single bets on all selections.
An examples of a winning Patent bet has been shown above. The other named bets are calculated in a similar way by looking at all the possible combinations of selections in their multiples and singles. For example, only two winners out of three in a Patent means the bet is settled as a double and two singles; only three winners out of four in a Lucky 15 means it is settled as a Patent ; only four winners out of six in a Lucky 63 means it is settled as a Lucky Thus, an each-way Lucky 63 on six horses with three winners and a further two placed horses is settled as a win Patent and a place Lucky The overall 'odds multiplier' is a combined decimal odds value and is the result of all the individual bets that make up a full cover bet, including singles if needed.
While the mathematical probability of an event has a value in the range from zero to one, "the odds" in favor of that same event lie between zero and infinity. It is 6 times as likely that a random day is not a Sunday. The use of odds in gambling facilitates betting on events where the relative probabilities of outcomes varied.
For example, on a coin toss or a match race between two evenly matched horses, it is reasonable for two people to wager level stakes. However, in more variable situations, such as a multi-runner horse race or a football match between two unequally matched sides, betting "at odds" provides a perspective on the relative likelihoods of the possible outcomes. In the modern era, most fixed odds betting takes place between a betting organisation, such as a bookmaker , and an individual, rather than between individuals.
Different traditions have grown up in how to express odds to customers, older eras came with betting odds between people, today which is illegal in most countries, it was referred as "odding", an underground slang word with origins based in the Bronx. Favoured by bookmakers in the United Kingdom and Ireland , and also common in horse racing , fractional odds quote the net total that will be paid out to the bettor, should he or she win, relative to the stake.
However, not all fractional odds are traditionally read using the lowest common denominator. Fractional odds are also known as British odds, UK odds,  or, in that country, traditional odds. Odds with a denominator of 1 are often presented in listings as the numerator only. A variation of fractional odds is known as Hong Kong odds. Fractional and Hong Kong odds are actually exchangeable. The only difference is that the UK odds are presented as a fractional notation e. Both exhibit the net return.
The European odds also represent the potential winnings net returns , but in addition they factor in the stake e. Favoured in continental Europe , Australia , New Zealand , Canada , and Singapore , decimal odds quote the ratio of the payout amount, including the original stake, to the stake itself. Therefore, the decimal odds of an outcome are equivalent to the decimal value of the fractional odds plus one. This 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.
When looking at decimal odds in betting terms, the underdog has the higher of the two decimals, while the favorite has the lower of the two. Decimal odds are favoured by betting exchanges because they are the easiest to work with for trading, as they reflect the inverse of the probability of an outcome.
Decimal odds are also known as European odds , digital odds or continental odds. Moneyline odds are favoured by American bookmakers. The figure quoted is either positive or negative. Moneyline odds are often referred to as American odds. A "moneyline" wager refers to odds on the straight-up outcome of a game with no consideration to a point spread.
In most cases, the favorite will have negative moneyline odds less payoff for a safer bet and the underdog will have positive moneyline odds more payoff for a risky bet. However, if the teams are evenly matched, both teams can have a negative line at the same time e. In gambling, the odds on display do not represent the true chances as imagined by the bookmaker that the event will or will not occur, but are the amount that the bookmaker will pay out on a winning bet, together with the required stake.
In formulating the odds to display the bookmaker will have included a profit margin which effectively means that the payout to a successful bettor is less than that represented by the true chance of the event occurring. This profit is known as the 'over-round' on the 'book' the 'book' refers to the old-fashioned ledger in which wagers were recorded, and is the derivation of the term 'bookmaker' and relates to the sum of the 'odds' in the following way:.
The true odds against winning for each of the three horses are , and respectively. This represents the odds against each, which are , and , in order. This value of 30 represents the amount of profit for the bookmaker if he gets bets in good proportions on each of the horses. And the expected value of his profit is positive even if everybody bets on the same horse. The art of bookmaking is in setting the odds low enough so as to have a positive expected value of profit while keeping the odds high enough to attract customers, and at the same time attracting enough bets for each outcome to reduce his risk exposure.
A study on soccer betting found that the probability for the home team to win was generally about 3. It was about 3. Making a profit in gambling involves predicting the relationship of the true probabilities to the payout odds. Sports information services are often used by professional and semi-professional sports bettors to help achieve this goal.
The odds or amounts the bookmaker will pay are determined by the total amount that has been bet on all of the possible events. They reflect the balance of wagers on either side of the event, and include the deduction of a bookmaker's brokerage fee "vig" or vigorish.

Archived from the original on 2 May Retrieved 10 December Archived from the original on 2 April The fundamental reason why all martingale-type betting systems fail is that no amount of information about the results of past bets can be used to predict the results of a future bet with accuracy better than chance.
In mathematical terminology, this corresponds to the assumption that the win-loss outcomes of each bet are independent and identically distributed random variables , an assumption which is valid in many realistic situations. It follows from this assumption that the expected value of a series of bets is equal to the sum, over all bets that could potentially occur in the series, of the expected value of a potential bet times the probability that the player will make that bet.
In most casino games, the expected value of any individual bet is negative, so the sum of many negative numbers will also always be negative. The martingale strategy fails even with unbounded stopping time, as long as there is a limit on earnings or on the bets which is also true in practice. The impossibility of winning over the long run, given a limit of the size of bets or a limit in the size of one's bankroll or line of credit, is proven by the optional stopping theorem.
However, without these limits, the martingale betting strategy is certain to make money for the gambler because the chance of at least one coin flip coming up heads approaches one as the number of coin flips approaches infinity. Let one round be defined as a sequence of consecutive losses followed by either a win, or bankruptcy of the gambler. After a win, the gambler "resets" and is considered to have started a new round.
A continuous sequence of martingale bets can thus be partitioned into a sequence of independent rounds. Following is an analysis of the expected value of one round. Let q be the probability of losing e. Let B be the amount of the initial bet.
Let n be the finite number of bets the gambler can afford to lose. The probability that the gambler will lose all n bets is q n. When all bets lose, the total loss is. In all other cases, the gambler wins the initial bet B. Thus, the expected profit per round is. Thus, for all games where a gambler is more likely to lose than to win any given bet, that gambler is expected to lose money, on average, each round.
Increasing the size of wager for each round per the martingale system only serves to increase the average loss. Suppose a gambler has a 63 unit gambling bankroll. The gambler might bet 1 unit on the first spin. On each loss, the bet is doubled. Thus, taking k as the number of preceding consecutive losses, the player will always bet 2 k units. With a win on any given spin, the gambler will net 1 unit over the total amount wagered to that point. Once this win is achieved, the gambler restarts the system with a 1 unit bet.
With losses on all of the first six spins, the gambler loses a total of 63 units. This exhausts the bankroll and the martingale cannot be continued. Thus, the total expected value for each application of the betting system is 0. In a unique circumstance, this strategy can make sense. Suppose the gambler possesses exactly 63 units but desperately needs a total of Eventually he either goes bust or reaches his target. This strategy gives him a probability of The previous analysis calculates expected value , but we can ask another question: what is the chance that one can play a casino game using the martingale strategy, and avoid the losing streak long enough to double one's bankroll.
Many gamblers believe that the chances of losing 6 in a row are remote, and that with a patient adherence to the strategy they will slowly increase their bankroll. In reality, the odds of a streak of 6 losses in a row are much higher than many people intuitively believe. Psychological studies have shown that since people know that the odds of losing 6 times in a row out of 6 plays are low, they incorrectly assume that in a longer string of plays the odds are also very low.
