The line opened two weeks ago with the Los Angeles Rams favored by one point. It took about an hour for the line to swing to the New England Patriots. It settled at Patriots as 2.5-point favorites for most of the past two weeks at sportsbooks tracked by OddsShark. Bovada and William Hill both offered a field goal, although William Hill came down to 2.5 over the weekend.

The over/under in this example has been set at 42.5.  If you project the Jets and Patriots to combine to score more than 42.5 points, you would place a wager on the over.  If you think they will score less than 42.5 points, you would bet the under.  Let’s say the final score of this game is Patriots 27, Jets 24.  Which bet would lose and which bet would win?  The sum of all points scored is 27 + 24 = 51, so an over bet wins and an under bet loses.

A parlay basically combines several different wagers into one. For example, a parlay could be made up of five point spread wagers on five separate games. The payout for such a wager could be very attractive, but only if ALL the wagers were correct. Just one wrong pick would mean the whole wager failing. That's why these are considered quite risky. They're a bit more complex than the previous wagers mentioned, but we won't go into any more detail here. We do on the following page though.
Understand that negative odds indicate how much money your must spend to make $100. When betting on the favorite, you take less risk, and thus earn less. When betting on a favorite, the moneyline is the amount of money you need to spend to make $100 profit. In the previous example, in order to make $100 of profit betting for the Cowboys, you would need to spend $135. Like positive odds, you earn back your bet when winning.
The Cronje Affair was an India-South Africa Cricket match fixing scandal that went public in 2000.[57] It began in 1996 when the-then captain of the South African national cricket team, Hansie Cronje, was convinced by Mukesh "John" Gupta, an Indian bookmaker, to throw a match during a Test in Kanpur, India. The scheme was discovered when Delhi police recorded illegal dealings between Indian bookmaker Sanjay Chawla and Cronje. According to the Telegraph in 2010, Cronje was paid off a total of £65,000 from Gupta.[58]
Like many high scoring sports, NFL wagering is dictated by the point spread. The spread, or line, is a type of side bet that equalizes the chance of winning a wager. The line offered for any given team will be accompanied with a – or + symbol to indicate whether a team is a favorite or an underdog. The example below displays the spread from the Sports Insights archives at the time of kickoff:

Betting on sporting events has long been the most popular form of spread betting. Whilst most bets the casino offers to players have a built in house edge, betting on the spread offers an opportunity for the astute gambler. When a casino accepts a spread bet, it gives the player the odds of 10 to 11, or -110. That means that for every 11 dollars the player wagers, the player will win 10, slightly lower than an even money bet. If team A is playing team B, the casino is not concerned with who wins the game; they are only concerned with taking an equal amount of money of both sides. For example, if one player takes team A and the other takes team B and each wager $110 to win $100, it doesn’t matter what team wins; the casino makes money. They take $100 of the $110 from the losing bet and pay the winner, keeping the extra $10 for themselves. This is the house edge. 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.


The sign in front of the number indicates whether placing a wager on that outcome will pay out more money then you have wagered or less money then you have wagered. If the odd is negative (-) it means that outcome is more likely to happen and placing a bet on that outcome would payout less than the amount you wagered, while a positive (+) odd shows that the outcome is less likely to happen and it would pay out more than the amount you wagered.
When betting off the board a calculation will be made according to the odds on each event in the parlay. You will win the same amount as if you bet each event separately and parlayed all winnings as you went. An exception is if every event you pick is at -110 odds, in which case predetermined nice round odds will be used. Except for a three-leg parlay, these preset odds are not as generous as if the calculation method were used. For this reason, it is a good idea to have at least one event in the parlay that isn't -110, which will force the calculation method to be used.
What's the difference between an oddsmaker and a bookie? A bookie's job is purely mechanical. He gets the line from Vegas or another source, offers bets at those odds, then collects money from the losers, pays out to the winners and keeps the vig. Oddsmakers don't actually take bets -- they study the games and set the lines. Bookies often adjust the spreads for their games, so they do a little oddsmaking, and oddsmakers work for casinos, which operate sports books that take bets.
Odds are basically a way of leveling the playing field and in college football due to the fact that there are hundreds of mismatches per year the field really does need to be leveled. By utilizing odds in various ways bookmakers are attempting to get an equal number of wagers on each team. In doing so, they are able to ensure that they make cash no matter who wins.
Oftentimes a point spread will not be a whole number, and will be accompanied by a decimal point and a half number. This can be significant for a point spread. Essentially what it comes down to is that a whole number point spread gives the opportunity for a wager to push. A push means that if the favorite is favored by 10 points and wins by 10 points, bettors get their money back. Just like when betting on the over/under total for points, the spread is a half-point in addition to the whole number, there is no chance to push.
Point Spread: The point spread remains the favorite way to wager on pro football, regardless of how many new forms of wagering come on stream. It’s called the line or spread and it’s known as betting ‘sides.’ The common misconception is that Las Vegas sets the spread as its best guess at the margin of victory. But really, it's a number they feel that is a perfect balance and will see an equal number of people to bet the underdog as on the favorite. A negative value like -6.5 means that team is favored by 6.5 points. So deduct 6.5 points from their total score. A positive value on the same game would be +6.5 (add 6.5 points to their final score) and would make that team an underdog of 6.5 points. The favorite must win by at least seven points to cover the spread. The underdog can lose by six points and still cover.
