Q:S1 Where can I bet legally on Sports?
A:S1 (Philip Galanter)

Leaving aside various forms of (animal) racing, there are at least four ways to
bet on sports in the US, and of these two are legal, one is illegal, and one is

You can bet legally at licensed Nevada Sports Books, and illegally with bookies
in virtually every town. Most of the following describes the ins and outs of
gambling at sports books. There are two points worth noting here. First, Nevada
Sports Books can set up phone accounts, but will not accept wagers across state
lines. Second, odds with illegal bookies are often worse than those one can get
in Nevada.

Betting with offshore (international) sports books seems to be on the rise, and
promises to spread from phone services to internet based online services. From
the point of view of bets and odds offered, these books are similar to licensed
Nevada Sports Books. The legality of these services is, at best, ambiguous.
There are claims and opinions on all sides of the argument, but few legal
precedents. In addition, some offshore books are run by old trustworthy firms,
some are fly-by-night scams, and many are somewhere in between. Cavaet Bettor.

The last way (and other than in state Nevada betting the only other clearly
legal way) to bet on sports in the US is the Oregon Lottery. This was described
as follows in a rec.gambling post:

     The Oregon lottery is alive and well as far as football betting. The
     game is called sports action. The line is set by Jim Feist. It is set
     and printed on Wednesday and does not change. This can work to the
     bettor's advantage due to changes in team lineups due to injuries and
     such. The minimum wager is $2.00 and the minimum number of games bet
     is 3. The payoffs for a three game win is $5.00 per dollar wagered.
     Four games gets $10.00 per dollar wagered. All other wagers are paid
     on a paramutual fashion. For example, a seven game winner usually
     pays around $160 to $350. The maximum number of games that can be bet
     have a winner. A week or two ago $14,000 carried over in the 14 pool.
     There are also some games that are called special play games with
     over/under total score. The line seems to be fairly consistent with
     the Vegas line on the Wednesday that it is set.


Q:S2 What sports can I bet on?

You can bet on any sport the Sports Book you are wagering with covers. At most
books, this includes professional and college football and basketball,
professional baseball, professional hockey, and horse and dog racing. Every now
and then Sports Books will offer proposition bets (see below) on events like
professional golf tournaments and the Indy 500 and the like, but not on a
regular basis for other events in those sports.

Q:S3 What is "the spread"?

The spread is a point advantage given to a weaker team that is expected to lose
by X number of points. This is the odds makers way of making even bets possible
for a Sports Book. Usually if you bet against the spread you make an 11-10 bet.
This means that you win $10 if you bet $11 for a total of $21 if your team
covers the spread.

A team covers the spread if it wins the game with the score modified by the
spread. If Dallas and Washington are playing and the spread is (Dallas -7),
then Dallas has to win by at least 8 points to cover. Half-point spreads are
also possible.

Q:S4 Why do I have to bet $11 to win $10?

This is one of the many ways the Sports book makes it's money. In an ideal
situation, the same amount of money will be bet on both sides of the line and
the Sports Book will take it's 10% from the losing side. If $55000 ($50000 and
an addition $5000 to make the bets) was bet on Washington and $55000 bet on
Dallas, no matter who wins the game the SB will make $5000. In case of a tie,
all money is refunded. This is a rather simplified version as the spread moves
when one side becomes more heavily bet on.

Q:S5 What are all of the different types of bets?

Proposition bet

A prop bet is a bet the SB offers at odds and conditions of it's choosing. Prop
bets can be exotic bets like which team will score the most touchdowns, which
team will shoot the most three pointers, which running back will rush for the
most yards, etc. Most prop bets are offered at 11-10 odds, but some of the
exotics will be offered at better or worse odds, depending on the bet.

Money Line Bets

A money line bet is a bet on the straight up total of an event or the odds for
a straight up prop bet. There are two totals given for either side on a money
line bet. A negative and a plus side.

                        Dallas          -170
                        Washington      +150

What this means is that for every $17 you bet on Dallas, you win $10 if they
win. For every $10 you bet on Washington, you win $15 if they win. This is the
way SB's make money off games by not giving points.

Spread Bets

These are the standard bets to make. Basically a proposition bet at 11-10 odds
where the conditions are you give or take points on the team you are betting on
hoping that the modified total of your teams score beats the other teams
straight score. Bets on the spread are often know as straight bets because they
pay even money (minus the 10% vig).

                        Tampa Bay       +19 1/2
                        Miami           -19 1/2

This means that if you bet on Miami, Miami needs to score at least 20 more
points than Tampa to cover. If you bet on Tampa, the score must be at least
within 19 for you to win. The bottom team is almost always the home team.

Over/Under Bets

These are also 11-10 bets on what the total of the game will be. If the total
posted on a game is 39 1/2 points, then you can wager that the total score of
both teams added together will be either over or under the posted total.
Betting the over is known as "betting on the ball", betting under is known as
"betting on the clock".

                        Chicago         -5 1/2  -180    1:00 pm
                        Atlanta         +5 1/2  +150    42 1/2

This gives the money line, the point spread, and the total for the game. It
also tells you that Atlanta is the home team, and the game starts at 1:00 pm.
As far as I know, this is the standard posting at mosts Books.


A parlay bet is betting on the outcome of two or more events, and getting
higher odds than betting on the outcome of both events. The drawback is that
the odds aren't right and that you must win all of the events to win the

                # of plays      Standard Odds   True Odds
                ----------      -------------   ---------
                2 plays             13-5           3-1
                3 plays             6-1            7-1
                4 plays             10-1           15-1
                5 plays             20-1           31-1
                6 plays             40-1           63-1
                7 plays             80-1           127-1

The more events parlayed the worse the odds shift in the casinos advantage. The
advantage for the player for parlays lies in the fact that he can bet more on
the same game (spread and over/under) and he can bet more on two teams who are
playing at the same time.

In order to be competitive, some casinos offer ties-win parlay cards. This
greatly helps the player. The Las Vegas Hilton SB is one of these.


A teaser bet is a bet where you can move the spread by a set amount, but have
to pay to do it. You must bet at least two teams like a parlay and win both.
You can move the spread by on all the games by the set amount.

Buying a half point

You can shift the spread a half point in your favor by laying 6-5 odds instead
of the standard 11-10. This is called buying a half point. You usually want to
stay away from this bet except on three point spreads on football games. This
is also know as "buying the hook".

Q:S6 Can I make a million dollars with one bet?

Sure. Bet $1,100,000 straight up.

Q:S7 Who makes the odds?
A:S7 (Philip Galanter)

Las Vegas Sports Consultants Inc., establishes the odds for about 75% of the
licensed Sports Books in Nevada, as well as for the Oregon State Lottery. It is
run by Michael 'Roxy' Roxborough. He also operates as a consultant on gaming
strategies, management, marketing, and personnel. Most illegal books in and out
of Nevada draw their odds from what is posted at the various casinos.
Transmitting gambling information across state lines for the purpose of placing
or taking bets is illegal. News items about point spreads and the like can be
reported for informational and entertainment purposes only.

Q:S8 Do I have to be over 21 to bet on sports?


Q:S9 What is the minimum bet that must be reported to the IRS?

Well all gambling wins and losses are supposed to be reported to the IRS at the
end of the year, but if you bet more than $10,000 at once, you must fill out
some IRS paperwork at the ticket counter. All money won must be reported to the

Q:S10 Are there any good books or articles on sports gambling topics?
A:S10 (Philip Galanter)

Here are some sports gambling related books I've found to be useful, in
suggested reading order for beginners. The obscure ones I've purchased from the
Gamblers Book Club, although I don't know if they are still in print. I tend to
like writers that are objective and more interested in your winning than being
a fan.

Orkin, Mike. "Can You Win?", W.H.Freeman and Co., 1991. IBSN 0-7167-2155-4

     Presents a general overview of gambling presenting the real odds of
     various games. It only assumes a high school level of mathematics
     understanding. The 32 page section on sports betting doubles as a
     guide to the various betting options available, and there is also a
     16 page section on horserace betting. A brief treatment on Kelly
     betting as applied to sports gambling is included.

     An overview concentrating on the question posed by the title, the
     author concludes the sports section with the observation:

     "If you're going to gamble, which games should you play? I recommend
     sports betting. There are two reasons for this: 1 - Unlike in
     roulette, craps, and keno, it's impossible to prove that you can't
     win in the long run. 2 - When you win, it's because you're smart, and
     when you lose, it's because somebody fumbled."

Sugar, Bert Randolph. "The Caesars Palace Sports Book of Betting", St. Martin's
Press, 1992. IBSN 0-312-05058-5 (paper)

     The author is a well known sports writer and Las Vegas insider. A
     good popular introduction to sports betting with equal amounts of
     information on betting terms, options, odds, and the like, various
     considerations for each major sport; advice on handicapping based on
     matchups, streaks, injuries and stat.s; history and color; and money

Manteris, Art, (with Rick Talley). "SuperBookie - Inside Las Vegas Sports
Gambling", Contemporary Books, 1991. IBSN 0-8092-4430-6 (cloth) 0-8092-3845-4

     A good second book to read, after perhaps the Sugar or Orkin books as
     an introduction, Manteris shares his observations as the Director of
     the Hilton Race and Sports Organization...aka the SuperBook.
     Interesting stories about the early days, why the house doesn't
     always win, how point spreads are set and moved as a practical
     matter, how the house calculates its take, scams, mob involvement
     (now mostly not) and more.

Peter Asch and Richard E. Quandt. "Racetrack Betting - The Professors' Guide to
Strategies", Praeger Publishers, 1986. IBSN 0-275-94103-5 (paper)

     Written by 2 academics from Rutgers and Princeton, this book seems to
     be a trustworthy analysis of betting at the horseraces. Included is
     an overview and analysis of popular strategies, subjective and
     objective analysis of available information and statistics, utility
     functions as applied to the public and wagering behavior (important
     given the paramutual basis of the odds), and the bottom line on some
     complex systems by the authors, Ziemba, and Quandt which seem to
     actually work.

Bob Carrol, Pete Palmer, and John Thorn. "The Hidden Game of Football", Warner
Books, 1988. IBSN 0-446-39091-7 (paper)

     While addressing sports betting only in passing, this book
     concentrates on innovative methods for detailed sports statistics
     analysis leading to accurate predictions. "Scientific" handicappers
     will find this book very stimulating.

Miller, Colonel J.R. "How Professional Gamblers Beat the Pro Football
Pointspread - a step by step textbook guide", Flying M Group, 1993. IBSN
0-9636500-0-9 (spiral bound)

     This is a self published specialty book available from Gamblers Book
     Club or by mail order. While the quality of most spiral bound
     gambling editions are suspect, this book is reasonably good. It
     provides a detailed analysis of how a serious gambler factors in
     pointspreads, power ratings, injuries, motivations, weather, and
     statistics to win over the long haul. The section on money management
     should be taken with a grain of salt, as it proposes flat betting as
     almost optimal, a modified plateau system as even better, and the
     "Kelly system" as a formula for disaster, in a rather unqualified

Michael Roxborough and Mike Rhoden. "Race and Sports Book Management - a guide
for the legal bookmaker", (publisher not noted) 1991. IBSN 0-31-53873-6 (spiral

     Written by "Roxy" Roxborough, the provider of the spread and other
     services to most major sports books in Nevada via his Las Vegas
     Sports Consultants Inc. This book covers in moderate detail the
     mechanics of running a legal sports book, including setting and
     moving the spread, various economic measures such as the handle and
     practical hold percentage, overlays, parlays, limits, the law and

Pascual, M. "Bankroll Control - the mathematics of money management",
(publisher not noted) 1987. No IBSN noted.

     While poorly published (xeroxed, white-out corrections, hand written
     corrections and page numbers) this odd and perhaps difficult to find
     spiral book is a treasure trove of practical analysis applying Kelly
     betting to sports and racing gambling. Theory is light and presented
     with (hand drawn) graphs where possible. The book presents a
     numerical recipe approach to even complicated betting scenarios such
     as simultaneous games, simultaneous single and multiple parlay plays,
     win-show-place betting, and more. Also included are some useful
     tables (variables include % of wins, number of teams, variations to
     include parlays or not) showing optimal bets, risk and expectancy.
     Also included are some program listings in BASIC for (now mostly
     obsolete) hand calculators that may be useful as pseudocode.

     The cosmetics do not, however, inspire trust. It would be nice if a
     r.g math weenie would review it.
