It underpins everything else that follows so getting comfortable with both the prices and what they represent is an important skill that's well worth learning. The price shown translates into a percentage chance of something happening or not. The table below shows a range of fractional odds and how they relate to the implied chances of that selection being correct. This allows bookmakers to set the odds for any given event - including a house edge - but also means bettors can compare their opinion to those of the person setting the prices and see what their return would be if their bet is correct at the odds on offer.
Because bookmakers are the ones setting the prices on their own websites or in shops, they have the luxury of building in a house edge when doing so. Much like the 0 on a standard roulette wheel or the 0 and 00 on an American one this is their opportunity to make their advantage count.
The amount of edge built into an event or a specific market can vary wildly across different operators and sports, but let's use football as an example. This doesn't mean that you can't make money betting on sports or anything for that matter but knowing the odds and what you're up against is key.
Consider the implied percentages here:. Thus, a draw is a possible outcome to bet on even in a game where one team must be eliminated. An example of what a 3-way moneyline would look like is:. The two possible wagers are:. For example, in a World Cup match between France and Switzerland, odds on the 2-way moneyline would like look:. Similar to betting the 2-way moneyline without the draw , the Goal Line is a way for bettors to win a bet on multiple outcomes of the game.
A Goal Line is typically 0. A World Cup match between Argentina and Iran looks like this:. If you bet Argentina Totals in soccer work differently than other sports and can be shown in multiples of. Since scoring is minimal in soccer, bookmakers will often times set a Total of 2.
This creates a number of other criminal elements, thus furthering their illegality. Sports betting has resulted in a number of scandals in sport, affecting the integrity of sports events through various acts including point shaving players affecting the score by missing shots , spot-fixing a player action is fixed , bad calls from officials at key moments, and overall match fixing the overall result of the event is fixed.
One of the biggest scandals of all involves the NBA Championship games. Tim Donaghy was allegedly gambling on the spreads for the games that he refereed. In the above example, if the bettor chose Miami, he would subtract 4 points from Miami's final score and compare that to Oklahoma City's final score. If taking Oklahoma City, he will add 3 points to Oklahoma City's final score.
If the final adjusted score is a tie, the bet is considered a push. The half point at the end is sometimes added to eliminate the possibility of a push. This is the most common type of bet in American sports betting. The possible payout of the parlay is determined by the combined likelihood of all bets placed. A parlay of riskier bets more underdogs will pay greater than a parlay of more likely bets more favorites. In a parlay, all bets need to win in order for the parlay to win.
If one of the bets on a parlay loses, the whole parlay loses. In the event of a push, the pushed bet would be taken out of the parlay and the parlay would bump down to a set of odds without that bet. Parlays are very appealing to bettors because they pay out much more than the total winnings of their constituent straight bets.
However, it is much more difficult to hit on a parlay than it is on a single wager. Although the rules to win his bet are the same as a parlay, he is paid less than a regular parlay due to the increased odds of winning. A sportsbook may choose to buy in-play futures wagers at a price below the actual payout before a championship is decided if the potential payout is very high and thus, damaging to the sportsbook due to the money that may be lost.
The bookmaker functions as a market maker for sports wagers, most of which have a binary outcome: a team either wins or loses. The bookmaker accepts both wagers, and maintains a spread the vigorish which will ensure a profit regardless of the outcome of the wager.
Bookmakers usually hold an 11—10 advantage over their customers—for small wagers it is closer to a 6—5 advantage—so the bookmaker will most likely survive over the long term. Successful bookmakers must be able to withstand a large short term loss. Boyd, Many of the leading gambling bookmakers from the s to the s got their start during the prohibition era of the s.
They were often descendants of the influx of immigrants coming into the USA at this time. Although the common stereotype is that these bookies were of Italian descent, many leading bookies were of eastern European ancestry. Odds for different outcomes in single bet are presented either in European format decimal odds , UK format fractional odds , or American format moneyline odds.
European format decimal odds are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2. UK format fractional odds are used by British bookmakers. US format odds are the amount won on a stake when positive and the stake needed to win when negative.
US odds of are an even bet. In Asian betting markets, other frequently used formats for expressing odds include Hong Kong, Malaysian, and Indonesian-style odds formats. Odds are also quite often expressed in terms of implied probability , which corresponds to the probability with which the event in question would need to occur for the bet to be a break-even proposition on the average.
In setting odds , the bookmaker is subject to a number of limitations: . In many countries, bookmaking the profession of accepting sports wagers is regulated but not criminalized. In areas where sports betting is illegal, bettors usually make their sports wagers with illicit bookmakers known colloquially as "bookies" and on the Internet , where thousands of online bookmakers accept wagers on sporting events around the world.
The National Football League is fully against any sort of legalization of sports betting, strongly protesting it as to not bring corruption into the game. On the other hand, the CEO of the International Cricket Council believe sports betting, in particular in India, should be legalized to curb illegal bookies where match fixing has occurred from nontransparent bookmakers. Many of the illegal proceeds also allegedly go to fund terror, drugs and other illegal activities.
The states of Delaware , Montana , Nevada , and Oregon —which had pre-existing sports lotteries and sports betting frameworks, were grandfathered in and exempted from the effects of the Act. Peter J.

Donald Hoover, FDU professor in International School of Hospitality and Tourism Management and former casino executive commented on the results, "Betting on sports is not an uncommon practice for many New Jerseyans, but for the most part, the state doesn't supervise it, doesn't tax it and doesn't take any revenue from it.
Woolley commented on the results, "If some states allow sports betting and profit by it, other states will want to follow. He announced on May 24, that he planned to go ahead and set up a system of wagering at the state's racetracks and casinos that fall, before the National Football League season ended.
In , despite federal law preventions, the state legislature of New Jersey and Governor Chris Christie signed a law that would allow sports betting to take place in New Jersey race tracks and Atlantic City casinos. Voters were asked whether New Jersey should allow sports betting even if federal law prevents it from doing so, or wait to allow sports betting until federal law permits it.

Pennsylvania ,  Rhode Island,  and West Virginia were able to pass legislation legalizing sports betting within their states. Some states must still organize which department will oversee state-regulated sportsbooks, most are choosing between their respective gambling commissions or lottery boards — until then no wagers can be legally taken. Pennsylvania became the seventh state to legalize sports betting when the state had regulations for sports betting in place in August Online sports betting in Pennsylvania began on May 28, when SugarHouse Casino launched an online sports betting app.

The positions of the four major American sports leagues representing American football , baseball , basketball , and ice hockey have become more complex since their decision to embrace daily fantasy sports DFS in , which are described by those within the industry as "almost identical to a casino" in nature.
With the contention by critics that such activities blur the lines between gambling and fantasy sports, the endorsement of all four major sports leagues and many individual franchises provided a marked contrast to their positions on betting. While the National Basketball Association NBA was once active in preventing sports betting law relaxation, current NBA Commissioner Adam Silver became the first major sports leader to break from previous administrative opposition to gambling.
In he stated in a New York Times op-ed, "I believe that sports betting should be brought out of the underground and into the sunlight where it can be appropriately monitored and regulated. Major League Baseball MLB Commissioner Rob Manfred has also advocated the league changing its stance on sports betting, with both Manfred and Silver noting that the scale of illegal sports betting makes opposition to betting meaningless.
He also stated a willingness to "try to shape" any future legislation at federal level. This was noted as a marked contrast to former Commissioner of the MLB Bud Selig , with Manfred going beyond tacit approval and stating, "There is this buzz out there in terms of people feeling that there may be an opportunity here for additional legalized sports betting. The National Football League NFL remains the only sports league to maintain public opposition to sports betting, however critics have noted that with the move of the Oakland Raiders relocation to Las Vegas in , the NFL has positioned itself for legalization, while simultaneously contradicting its long-held position that sports betting in NFL markets would lead to potential match-fixing.
The NHL was the first major professional league to place a team in Nevada, when the expansion Vegas Golden Knights took the ice in since then the league has signed sponsorship agreements with William Hill and MGM Resorts International that include betting partnerships and access to in-play data. Other clubs in states with legal sports gambling, such as the New Jersey Devils and Philadelphia Flyers , also have similar sponsorships with bookmakers.
Commissioner Don Garber has stated about sports gambling, " We have a project going on now to really dig in deeply and understand it. The American Gaming Association stated in June , that a coalition will advocate for the repeal of the United States' sports betting ban. In February , a lobbying document surfaced advocating a new position held by the NBA and MLB — that sports leagues should be financially compensated for betting activity.
The Football Association , the governing body for association football in England , has imposed football betting bans on all individuals involved in the sport—players, managers, match officials, and club staff. The scope of these bans varies based on level of the English football pyramid.
The following individuals are banned from betting on any football-related matter worldwide, or providing inside information to any individual who can reasonably be assumed to use said information for betting purposes:. Individuals who are associated at clubs at lower levels of the men's or women's league systems, plus match officials at FA Level 4 or below, are only banned with respect to the match or competition in which they are involved or can influence, and also to the league in which they participate.
All individuals are banned from advertising or promoting any football betting activity in which FA regulations prohibit them from engaging. This, however, only applies to individuals in their personal capacities. For example, if a club is sponsored by a betting company and said company places its logo on the club's kit, the team's players are not in violation of the betting rules.
The World Baseball Softball Confederation , the international governing body for baseball and softball , has betting rules similar to those of Major League Baseball. Participants in any WBSC-sanctioned event are banned from betting on the following: . The betting ban, as in the case of The FA's rules outlined above, also extends to providing inside information that the tipper could reasonably believe will be used to bet on a WBSC event.
The International Cricket Council imposes a blanket ban on what it calls "corrupt conduct" by anyone it defines as a "participant". The ICC shares anti-corruption jurisdiction with national cricket federations, all of which have anti-corruption rules substantially identical to those of the ICC. The ICC has elaborate mechanisms for determining whether it or a national federation will take action under the relevant anti-corruption code.
In general, the ICC has either exclusive or priority jurisdiction over international matches, while national federations have responsibility for actions relating only to domestic matches. The ICC code bans the following activities with regard to any international match, whether or not the participant had any involvement in said match, or any possible means of influencing the outcome:.
This series would go down as one of the biggest sports scandals of all time. All eight players were banned from playing professional baseball for the rest of their lives. The rule against gambling in baseball is known as "Rule 21," which is publicly posted on dugout walls and states: "Any player, umpire, or club or league official or employee, who shall bet any sum whatsoever on any baseball game in connection with which the bettor has a duty to perform shall be declared permanently ineligible.
For instance, Mickey Mantle and Willie Mays were both banned from baseball in after taking jobs as casino greeters which would have expelled them from the Hall of Fame had it been allowed to stand ; they were reinstated two years later. Only Rose has yet to be reinstated. A betting scandal between the Massillon Tigers and Canton Bulldogs , two of the top teams in professional American football in the early s, led to the demise of "big-money" professional football for several years.
Modern research has suggested that the claims of betting were unsubstantiated. On December 7, the San Francisco 49ers overcame a halftime deficit of 28 points in what became the greatest regular season comeback victory in NFL regular season history.
Rosenthal was able to retain these winnings despite the final outcome of the game due to gambling regulations previously established by the NAGRA.

Archived from the original PDF on July 23, Since the first bookmakers began taking wagers on chariot racing and gladiator matches in Ancient Rome, betting on sport has become one of the most popular pastimes in the world.
The multitude of adverts and sponsorships within football has made gambling almost an integral part of the game, although it can still be daunting for new players. A football match result, however, has three outcomes home win, draw, away win — also known as 1X2 and because it relies on aspects like player ability, the three potential outcomes are rarely offered at exactly the same odds. Theoretically, then, the bookie edge would be 2. If a bookie takes equal amounts of money on both sides, they will make around 2.
If a bookmaker takes considerably more bets on one side of the market than others, meaning they have more liability and will not guarantee a profit, they will adjust the prices to make the popular selection less attractive. Generally speaking, the adage that the house always wins is true. The phrase comes from casinos where games are consistent across different companies and there is very little variation.
Almost every casino will offer roulette and the house edge in that game is the zero.
Liverpool home games are less likely to produce the 3 goals that their overall average illustrates. In simple terms, this means bets on a Man City win and a Liverpool win at their respective home grounds represent the most likely minimum of results. So any betting enthusiasts looking at Liverpool fixtures may want to keep this in mind when selecting a bet for both teams scoring, for example.
Arguably the most critical view of goals, however, is that of recent form. One of the most common and trickier bets to play are those relating to timing, be it goals in the first half vs the second half, goals in specific minutes. Using the simple tables provided by www. These numbers are useful to guide the potential of bets for scorelines and goals between the first and second halves of matches.
A similar insight is revealed by looking at goals conceded by minute, and intriguingly, the top 3 sides in the league tend to conceding in the 1 st half of matches, rather than away. Another popular bet available to examine is that of the relationship between winning at halftime and and at fulltime. This table, available from www. Some revealing insights; of all the sides in the top 6, Liverpool have dropped the most winning positions 3 between halftime and fulltime.
Spurs and Chelsea have yet this season to convert a losing position at halftime to a winning one by the end of the match. The statistic for winning each half poses an interesting contrast to the extent where these sides score the first goal:. The curious statistic in the example above is that of Liverpool, who are above the top 6 average in all respects, but remain a side that struggle to hold onto the strong advantage they typically start with.
