Real Money Sports Betting in 2021

We’ve published multiple pages about “real money” gambling.
Most of these pages distinguish between real money versions of
various casino games and the corresponding free versions of
those games. But when discussing “real money sports betting”,
we don’t really have a “free sports betting” activity with which to
contrast the activity.

Instead, when people talk about real money sports betting,
they’re talking about betting for meaningful amounts of cash.
A lot of times, they’re interested in how to bet on sports online,
but some of them are interested in getting some money into action with a bookmaker. In the United States,
betting on sports presents some interesting legal questions, too.

This page presents a broad overview of how the business works, which sports are most commonly wagered
on, and how the various bets work. The links from within the page go to more detailed pages on specific

Sportsbooks and Bookmaking

Many people just make bets on the outcome of a game with their buddies. If your buddy at work wants to bet
you $20 that the Cowboys are going to win Monday night’s game, then that’s a so-called “simple wager”.
That’s not really the kind of sports betting we’re interested in on this page.

When you start putting real (significant amounts of) money into action, you have to find someone who’s
willing to take the other side of that bet. Luckily, some people are in the business of taking this action.

Those people are called “bookmakers”, and the
businesses they run are called “books” or “sportsbooks”.

In the United States, placing such a wager over the phone is illegal because of the Wire Act. As a result, the
only legal businesses taking this kind of action operate out of Las Vegas, Nevada. And they don’t accept
action over the phone or the Internet. You have to show up there to place bets.

But anyone who’s spent any length of time in a neighborhood bar knows that plenty of entrepreneurs are
willing to skirt the law in order to take your bets. These are the neighborhood bookies that you see in the
movies. Unless and until their businesses get incredibly large, these neighborhood sports books generally
operate unimpeded by law enforcement.

In other, more enlightened, countries – like the United Kingdo – sports betting as a business is legal and
regulated. We’re fans of this approach. The libertarian in us feels like citizens should be allowed to spend
their money on whatever they want to, even if that includes wagers on sporting events.

Also, when you’re dealing with a licensed and regulated business in the industry, you have certain
protections that aren’t available when you’re dealing with a neighborhood bookie. If you’re reminded of the
dangers of “bathtub gin” and “moonshine” during Prohibition, then you know what we mean.

No one is suggesting that betting on sports or drinking alcohol are the best uses of your time and/or money.
But people are going to bet on sports and/or drink alcohol regardless of the legality. So why not put the
government to work protecting the safety of its citizens?

Regulated distilleries and breweries provide a healthy, safe product for consumers to imbibe. We contend
that the sports betting industry would be safer for individual sports bettors if it were entirely legal and
regulated throughout the United States. At the same time, we don’t think that legalizing and regulating
sports betting is going to be high on any legislators’ agendas any time in the near future.

How Odds Work in Sports Betting

When you’re betting with a bookmaker, they need to make sure that they have an opportunity to break even
and make a bit of profit while they’re at it. They can’t do that by just taking action willy-nilly. For example, if
the Dallas Cowboys are playing the Cleveland Browns, all of the bookmaker’s customers are going to bet on
the Cowboys. And most of the time they’re going to win.

In order to get action on both sides of a wager, the bookmakers use odds to make both bets attractive. This
is often in the form of bets which pay off at a higher amount the less likely they are to win. We provide an
overview of the different odds formats below, or you can read in more detail on the following page.

American Odds (Moneyline Odds)

In most sports in the United States, “American odds” or “moneyline odds” are used to make wagers attractive.
You can usually bet any amount (with certain minimums) in these situations, but the odds are represented
with the amount of money compared to $100.

  • If the odds start with a minus sign, then that’s how much you have to bet in order to win $100
  • If the odds start with a plus sign, then that’s how much you win if you bet $100

Here’s an example. If the Cowboys are favorites against the Browns, you might see the odds listed as follows:

Cowboys vs Browns
Match Winner

So you’d have to risk $120 to win $100 if you bet on the Dallas Cowboys.

You’d only wager $100 on the Browns, but if you won, you’d win $115.

This makes both wagers attractive. On one hand, you have a better chance of winning if you bet on the
Cowboys, but you don’t win as much for your money. On the other hand, you might win fewer bets on the
underdog (Cleveland), but when you do, it’s going to pay off better.

In these situations, a point spread isn’t used.

Decimal Odds and Fractional Odds

Not all countries (nor all bookmakers for all bets) use this format to represent the odds. Books in other
countries often use decimal odds and/or fractional odds. These have the same effect, but they’re a different
way of representing how much you stand to win or lose.

We think decimal odds are more intuitive and easier to understand, and we’re not sure why moneyline odds
became so popular in the United States. With decimal odds, you’re just looking at a multiple of how much
you bet. This indicates how much you’ll win.

Here’s an example.

Cowboys vs Browns
Match Winner

These are the same odds that we used in our first example, they’re just represented differently. If you bet
$100 on the Dallas Cowboys, you’ll get $183 back ⁠— the $100 you bet plus an $83 profit. If you bet $100 on
the Cleveland Browns, you’ll get $215, the original $100 you bet plus $115 in profit.

Sports Betting Odds: An Important Consideration

The betting odds never represent the true odds of one team or another winning. All of these bets pay off at
less than the true odds that the handicapper expects. That’s how a bookmaker generates a profit.

If a bookie offered bets at the true odds of winning, he’d break even. In that case, he would have spent all the
time and effort running his business only to make no money. Few people love sports betting enough to do

Most books are looking to make between 10% and 20% profit. Their goal with these kinds of odds is to get
even money on each side. That way they can pay off the winners with the losers’ money, keeping the
difference as their profit. You can read more about bookmakers and their methods for making money on the
following page.

Sports Betting Sharps

“Sharps” are sports bettors who are good enough at handicapping that they can recognize when the
professional handicappers or books have errors in their odds, presenting a profitable situation.
Handicapping sports at such a level is hard, especially considering how sophisticated professional
bookmakers have become.

But knowing how to achieve a positive return when betting real money on sports is the most profitable
advantage gambling opportunity we know of. It’s heads and shoulders above the other possibilities, which
include blackjack (counting cards), poker (expert play), and video poker (again, expert play).

Is It Legal to Bet on Sports?

It’s illegal in the United States to run a sports betting business, but some states are exceptions. These include
Delaware, Montana, Nevada, and Oregon. And even in the case of those states, you’re not allowed to place
wagers on sporting events using any kind of telephone or Internet line. That’s what the Federal Wire Act is all

Polls seem to indicate that legalization of sports betting in the United States has limited support. Professional
sports organizations, especially the NFL, contend that legal wagering would corrupt the integrity of the game.
How they come to that conclusion is anybody’s guess, as plenty of illegal wagering seems to have left the
integrity of the games intact.

In other countries, especially in Europe, sports betting businesses are legal and regulated. As we mentioned
earlier, that kind of situation provides a certain amount of protection for the consumer. It’s a lot less likely
for a licensed, regulated corporation to disappear with their winnings after the Super Bowl than it is for
Charlie the local bookie you met through your buddy at the bar in Anytown, USA.

Enforcement activities in the United States are generally restricted to people operating illegal sports betting
businesses, but even in those cases, enforcement is pretty lax. It’s impossible to find accurate statistics
regarding the size of the illegal sports betting industry in the United States, but we’ve seen estimates as high
as $400 billion a year. An estimated $95 billion is wagered on the Super Bowl alone every year.

Sports That Are Commonly Bet On

Any sport with an uncertain outcome is a sport that someone can place wagers on. The types of wagers vary
from sport to sport, and some sports generate more action than others.

We’ve included an overview of the sports which generate the most action throughout the world below, along
with a brief explanation of each and how betting on it works.


Baseball is, of course, the national pastime in the United States. Most baseball bets are made on the
moneyline, total, runline, and/or future. We explain how those bets work in the next section.


Basketball is hugely popular, both professionally with the NBA and college with the NCAA. The easiest way to
place a bet on basketball is to place a point spread bet, which we explain in the next section. Totals bets and
moneyline bets are also common.


Boxing has waned in popularity since its glory days. MMA and the UFC are rising in popularity, but boxing isn’t
dead yet. The most common bet on a boxing match is a moneyline bet on who will win, but prop bets on
which round the fight will end in are also common.


Since we serve a large number of Americans, we’ll explain that cricket is similar to baseball with no intention
of offending our international readers who know what the sport is. The same kinds of bets that are popular for
baseball are also popular when betting on cricket. Most Americans don’t bet on cricket, but Australians (as
well as UK and Canadian bettors) love to bet on this sport.


Betting on cycling includes betting on such events as the Tour de France. Simple bets on the winner, using
fractional or moneyline odds, are the most common.


In the United States, darts is often considered a “bar game” in the same way that billiards and shuffleboard
are. Wagers among the participants, especially tournaments, are common. But most Americans aren’t placing
bets on darts via a sports book, though. Punters in other countries, do, however. These bets focus on
2 professional organizations devoted to the sport:

  • The British Darts Organisation (BDO)
  • The Professional Darts Corporation (PDC)


This is a relatively new category of sports betting. E-Sports are competitive events held between players in
various video games. A wide variety of video games are popular in this category, and many of them are played
in a tournament format. The E-Sports available to bet on vary widely depending on which online bookmaker
you’re using.


In the United States, football is probably the #1 sport to bet on, especially during the Super Bowl. The NFL
(National Football League) is the professional arm of the sport, while college football (NCAA) is also popular to
bet on. A bewildering variety of bets are available in football, but moneyline bets are as common as any other.


Golf, like baseball, seems to be a game that anyone can play, but at the professional level ⁠— not so much.
Betting on golf is mostly focused on the professional version of the sport, the PGA. The most common golf
bet is the “odds to win” wager, but head to head bets are also common. Futures and group matchups are also


Handball has its fans in the United States and in other countries, but it’s most popular in Germany and Spain.
Match betting, handicap betting, total goal betting, and futures are the most common wagers.


Hockey, especially the NHL, has been steadily growing in popularity. And since it’s not quite as popular as
football or basketball, you can often find lower betting limits and better lines when betting on hockey. The
moneyline is the most common bet, but puck line bets and totals are also popular.

Horse Racing

Horse racing is so different from most other types of sports betting that it’s almost considered an entirely
different sport. A bewildering number of bets are available, but win, place, and/or show are probably the most
common.Entire sites, books, and magazines are devoted to getting an edge at horse betting.

Motor Sports

Betting on motor sports includes betting on any kind of car racing, but the most popular are NASCAR and
Formula 1. These bets are similar to most other bets on races or sports with individual participants, like golf.


You won’t find many people placing real money bets on rugby in the United States, but it’s a hugely popular
sport in Europe. The common bets for this game have interesting names, like “supremacy”. Futures, season
points, first try scorer, outright winner, and match bets are also big.


Snooker is another sport (like darts) which most Americans wouldn’t think to bet on, but it’s popular in other
countries in Europe. The easiest bets are on who’s going to win a match, but there’s also handicap betting
and market betting.


Soccer is as popular in Europe as football is in the United States. In fact, we should ask our European readers
to forgive us for not using the word “football” in its more common international meaning ⁠— Americans, soccer
is called football in most parts of the world. Moneylines, goal lines, and totals are all popular bets for soccer.


Prop bets and moneyline bets are the most popular wagering forms for this sport.


The UFC has almost completely overtaken boxing as the most popular sport involving fighting throughout
the world, although other MMA organizations do exist. Betting on UFC and MMA events is similar to betting
on boxing.

Common Types of Sports Bets

2nd Half Bets

A 2nd half bet is a bet on the outcome of the 2nd half of the game. This bet is commonly made my punters
who aren’t doing as well during the first half as they had hoped they would.

Future Wagers

Futures are similar to investments in the stock market. They’re wagers on events that are going to happen at
some point in the future. One common futures bet is a bet at the beginning of the season on who the
champions will be at the end of the season ⁠— you can bet on who’s going to win the Super Bowl or the World
Series way in advance, and the payoff if you win is great.

Goal Line, Puck Line and Run Line Bets

These are bets where the number of goals, pucks, or runs is taken into account when determining the
winner. They’re similar to point spread bets.

Head-to-head Bets

A head to head bet is a straightforward bet on who’s going to win a particular match, but in some sports
with multiple participants, you can single out two participants and bet on which one will do better.

If Bets

“If bets” resemble parlays. They’re great for players with small bankrolls. You place multiple bets, but the
bets depend on the outcomes of your preceding bets.

In-Play Betting

This refers to bets that are being made while the event is actually happening. This is also commonly called
“live betting”. Almost any kind of bet can be made “in-play” as well as before the match, but not all of them.
(For example, you obviously can’t place a futures bet during the Super Bowl.)

Moneyline Bets

These are the most common types of wagers punters make. They’re just wagers on a particular team to win,
and the amount of money won is based on how likely the bookmaker thinks it is that one team is going to
beat another team.


A parlay is a bet on multiple events. For example, a bet on the winners of 6 different games would require
you to win all 6, but the payoff would be great.

Point Spread Bets

These are the most common bets you’ll see in football. The favorite has to win by a minimum number of
points to be considered the winner for purposes of winning this bet. A bet on the loser wins if the favorite
doesn’t beat the spread.

Progressive Parlays

These are parlay bets on between 4 and 12 outcomes that offer especially large payoffs if you get all your
picks correct.

Positions Bets

Proposition bets are also called prop bets. It’s a bet on something that happens during an event that doesn’t
necessarily have a direct effect on the outcome. For example, a bet on how many touchdowns a particular
quarterback will throw during a game is a prop bet.

Simple Wagers

This is the phrase we use to describe a small bet you might make with one of your buddies, but it’s also
often used to describe some of the more straightforward wagers you can make with a book. Moneyline bets,
for example, are simple wagers.

Spread Betting

Spread betting is another phrase used to describe point spread bets, but it’s also commonly used in financial


Teasers are similar to prop bets, but you get to adjust the point spreads or totals in your favor. In exchange,
the book offers you a lower payout on your bets.

Online Sports Betting for Real Money

If you’re in the United States, you’re limited to dealing with neighborhood books or online sports betting
companies if you want to place a wager on an event without traveling to Las Vegas. Each option has its pros
and cons.

Betting with a neighborhood bookie can be fun, especially if it’s someone you get to know personally. Chances
are some of your buddies also do business with this person. You can usually get your winnings faster when
dealing with someone local, too. You can also avoid a lot of the money transfer fees and hassles associated
with online sports books.

On the other hand, most neighborhood bookies don’t offer anywhere close to the variety of options when it
comes to which wagers you can place. They don’t always offer the same selection of sports to bet on, either.
And they often have lower betting limits than online books.

Another big perk to using an online book is the signup bonus that’s available. Almost all Internet bookmakers
offer matching bonuses on your first deposit as a customer. It’s an incentive to get you to sign up there.
Some books even offer free bets with no deposit required. Good luck finding that kind of perk with someone
in your neighborhood.

Whether or not your online bookmaker is as shady as your neighborhood bookie is a question you’ll have to
determine. Some Internet books are more reputable than others, but so are some neighborhood books.
We always suggest caution and an “eyes wide open” approach when doing any kind of betting.

You can find detailed reviews of several recommended online sports books on our site by clicking on the
links below. These sites are all reputable and take good care of their customers.


Bet365 Logo

Bet365 is one of the biggest names in the business, but sadly, they don’t accept players from the United
States. If you’re placing bets from the United Kingdom or elsewhere in Europe, bet365 should be high on your
list of sites to consider, though.


BetOnline Logo

BetOnline is an all-in-one betting site that offers casino games, poker, and sports betting ⁠— all for real money.
They have a large number of deposit options available, which is a great perk. Unless you’ve experienced it
first hand, you would be amazed at how hard it can be to transfer money to and from a betting site.


Bodog Logo

Bodog is one of the glitzier and better known names in the industry, largely because of the antics of its former
owner, Calvin Ayre. For such a famous name, they provide only average betting lines, and they no longer
accept players from the United States. We like Bodog, but not as much as we like bet365 or William Hill.


Bovada Logo

Bovada is probably the best-known and most popular site which accepts real money sports betting from
gamblers in the United States. It’s a full-service site, too, which means you can also play casino games and
poker there.

SportsBetting Logo

SportsBetting offers one of the largest initial signup bonuses in the business ⁠— it’s a 25% match of up to
$1000. If you’re serious about betting some big money, then this is a site worth investigating.


TopBet Logo

TopBet is a relatively new player in the online sports betting for real money space, but they have a good
reputation already. They offer one of the best new player signup bonuses in the business, and they are U.S.
player friendly.

William Hill

William HillLogo

William Hill is a well-known bookmaker operation in Europe that operated as a brick and mortar business
long before launching an online presence. Their reputation is sterling, but they don’t accept punters from
the United States.

You should look for the scuttlebutt on any online sports betting company you do business with before making
your first deposit, especially if you’re giving action from the United States. Because of the iffy legal situation in
this country, the companies who are willing to do business with US customers are never public companies
and are sometimes on the shady side.

Read through player forums to get an idea of what kinds of problems other bettors have reported about
certain sites. And be skeptical of sports book reviews on the Internet that are too “glowing”. People running
sports betting information sites earn big advertising money from these corporations, and that can influence
their ratings and reviews.

A good rule of thumb is to ignore reviews from information portals that lack easily-found “about us” and
“contact us” pages. You should also look for balanced reviews that evaluate the pros and the cons of a site.
No website is perfect for every customer. A well-written review takes that into account.

Also, if you’re from the United States, you do need to be aware that betting on sports for real money online
isn’t exactly legal. In fact, it’s clearly illegal. You have to make your own decisions about such things, but our
official advice is to obey the laws in the jurisdiction where you live.

That being said, when’s the last time you heard about someone getting arrested for placing a bet on the
Super Bowl over the Internet?

Or with your neighborhood bookie, for that matter?


Real money sports betting refers to placing wagers of a respectable size on various sporting
events. The number of wagers available is staggering, but most of them are simply
moneyline bets expressed in one of two different odds formats. If you live in the United States,
the legality of betting sports for real money online is questionable at best, but readers in
Europe have lots of legal, regulated options to choose from.

Be sure to educate yourself before deciding on a sports book at which to play. Err on the side
of caution, and start off small.

Once you’re comfortable with a company, you can start raising the amounts of money you
want to wager with them.
