One of the first rules of gambling is that nothing is ever certain. There's one thing that's almost certain though; you will make mistakes as a beginner. This is nothing to worry about, and in fact making mistakes is an important part of the learning process. That doesn't mean you need to make unnecessary ones though. There are a few mistakes that are routinely made by beginners, and it pays to be aware of these.

Sports betting has been around since 1000 B.C in China, where betting on animal fights was commonplace. In ancient Rome, one could wager on the Gladiatorial games. The idea of betting on sports is as old as organized sport itself. But up until the 1940s, bettors were fairly limited in what kind of bets they could make. The standard system of odds would allow bets on, for example, the 3-1 odds that the Steelers would beat the Browns.

A point spread in sports is a figure set by oddsmakers to provide an advantage or disadvantage based on the margin of victory or defeat for a given team. The “favorite” team (labeled with a “-” sign) would be at the disadvantage as they would need to win the game by a set number of points while the “underdog” team (labeled with a “+” sign) would be given an advantage to not lose the game by a set number of points. The reason oddsmakers do this is to provide betting interest for both sides due to one team typically being better than the other.

Chicago is the NFC North champion for the first time since 2010, which was the franchise’s last trip to the playoffs. These franchises haven’t met in the playoffs since January 2002. They played in the 2017 regular season and the Eagles rolled to a 31-3 home victory. This Bears team is miles better than that one. Philly’s QB situation for this one is a bit unclear at the moment because Carson Wentz has missed the past three with a back injury and Nick Foles left Sunday’s win with a chest injury.

Another way to beat football point spreads is to shop for off market prices. For example, let's say you're shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn't quite the same as simply shopping for the best lines. Here, you're specifically looking for wagers that are +EV because they're against the market.
The point spread, which is sometimes referred to as the “handicap”, is the number of points taken from the favorite, or given to the underdog, in order to open up the chances of either team winning the wager evenly. In most games, there’s usually a team that is more likely to win, based on a number of statistical factors. If the only kind of wager available was on who would win between a very strong team and a poor team, it wouldn’t be all that exciting. The point spread was designed to make betting much more interesting, since it allows a bet on the losing team to win you money. How? Let’s break down an example:

"There’s only so much discretionary income in the Commonwealth, and if this new form of betting taps into it, we feel our sales could be negatively impacted, which in turn could effect proceeds to the Commonwealth," Polston said in an email. "As those proceeds fund college scholarship and grant programs — including every dollar of the popular KEES scholarship — there’s a lot at stake here."

The Patriots are set to take on the Rams in the greatest show on turf and money has been flowing into both sides of the Super Bowl 53 point spread. The Patriots are -3 for SB LIII according to most legal online sportsbooks but some have them listed only at -2.5. The Rams and Patriots are both offensive minded, and capable of scoring quickly; therefore, the winner will likely be whoever scores last in the game (-180). There is still no discussion of whether the roof will be open or closed at Mercedes-Benz Stadium in Atlanta, so weather may or may not play a factor here. Either way, make sure to get in your bet on the spread for Super Bowl 53, whether you choose the Patriots or Rams, before the 6:30 EST kickoff on Sunday, February 3rd.

Also known as NFL OVER/UNDER betting, the total is the number set by sportsbooks that estimates the total number of points scored by both teams combined. Bettors then must predict whether there will be more or fewer points than the NFL “total.” If you bet the 37.5 UNDER, you are hoping for a defensive battle and predicting the offenses to struggle. If you bet the 37.5 OVER, you are hoping this will be a high-scoring game.
A point spread - Lets take, for a hypothetical situation on one of the types of football bets (using the point spread), that the Kansas City Chiefs were visiting the Detroit Lions and Detroit was established as a six-point favorite at game time, which is commonly written as Detroit -6. Kansas City would be the underdog and displayed as Kansas City +6. If you bet the favorite, Detroit has to win by more than six points to win your bet. Remember, the Lions are favored by six points, so we subtract six points from their final score on a spread bet. If Detroit were to win 27-20, Lions bettors would win their wager. If the Chiefs were to win the game by any score and you picked the Chiefs you would win not including the extra six points. If the Lions were to win, 20-14, it would be exactly six and a push, so you would get your money back.
If you bet on the point spread, you’ll often see -110 placed next to each betting option. That means that you have to bet $110 to win $100. The $10 difference is effectively a fee you are paying to place the bet. It can be referred to as the juice or the vig (short for vigorish, which originates from the Russian word for winnings). If there is an even amount of money bet on both sides of the line, the juice guarantees a profit for the house.
The most common NFL spreads are usually set between about 2.5-10.5 points, but you will also almost always have games each week with spreads lower than 2.5 and higher than 10.5. In the event that the oddsmakers feel the game doesn’t need a spread, it would be set at 0 or what some call a pick’em (both teams are given even odds to win for this type of bet).
Another way to beat football point spreads is to shop for off market prices. For example, let's say you're shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn't quite the same as simply shopping for the best lines. Here, you're specifically looking for wagers that are +EV because they're against the market.

The point spread will list one team in the negative and the other in the positive. (Unless neither team is favored, then they will be listed as EVEN or PICK). The club posted in the negative with a minus sign is favored and so the bookies take points away from them, which means that team must win by at least a certain number of points to cover the spread. The underdog will have a plus sign and will cover if they win outright or lose by less than the posted number.

It’s common knowledge among bettors that the online gambling industry pays close attention to Las Vegas Sports Consultants, a private company that handles the odds for casinos and newspapers. But the totals I set have to reflect our customers’ preferences for betting the over or under on certain teams in certain situations. Also, because LVSC lines are published early, I have to keep on top of injuries and potential changes in coaching strategy leading up to the game in question before I release any totals. This is doubly important in basketball, where pace determines how many shots will be taken in 48 minutes.
A few other small factors to look at would include recent matchups between the two teams, home and away records of the two teams, the way the teams have played in the past 3-4 weeks (hot streak/cold streak), and also any injuries to stars that could affect the overall game plan of team.  How does a football team do off a loss, off a win, etc.  Start adding some of these suggestions to your repertoire and I guarantee your sports betting bankroll will keep growing each football season.
The most famous historic example of this is Super Bowl III when the New York Jets stunned the football world and upset the Baltimore Colts. The Jets were 18-point underdogs, still the largest point spread in Super Bowl history. They won 16-7, and people wondered what the oddsmakers had been thinking. Noted oddsmaker Bob Martin was later asked if he was embarrassed making the Colts such huge favorites. He said he was not because in what was then one of the heaviest bet sporting events ever, his number drew a fairly even amount of bets on both sides. This guaranteed a profit for the house.
Once you have selected the appropriate sport, league and game, the betting options appear. A betting option is, for example, the winner of a game, how many goals will fall or how many fouls, penalties, corners and free kicks there will be. For football matches in the first leagues, there are usually around 40,000 different betting options available for almost every country. The large offer may seem deterrent, but the betting providers solve the problem with a very good overview as well as a function to find the desired betting option quickly and easily. There's a odds on every betting option. This number indicates how likely a betting option is. If the odds are high, the profit margin is also high, but the probability of the event occurring is very low. An example of this would be if a third division team won against a first division team. If the rate is low, the event is very likely. So in terms of the example that the favorite will win the game. The process of a bet reads longer than it is. After the first bets, the process has already turned into flesh and blood and you can place betting options every minute. Of course, only if you have informed yourself about sports and betting in detail beforehand, because this is the only way to make sports betting with responsibility and a good chance of success possible.

All this means to someone betting on New England is that in order for them to win their wager the Patriots must win by more than four points. For another bettor placing his money on Seattle, the Seahawks must either win the game outright or lose by less than four points. If the outcome of the game were to be decided by exactly four points, it what result in what is called a “push” where both bettors would neither win or lose their wager.
The point spread is the projected number of points that separate two teams.  A game with a spread will have a favorite (the team expected to win) and an underdog (the team expected to lose).  A favorite “gives” points and is identified with a minus sign next to their point spread.  The underdog “gets” points and is identified with a plus sign next to their point spread.

The point spread is essentially a handicap towards the underdog. The wager becomes "Will the favorite win by more than the point spread?" The point spread can be moved to any level to create an equal number of participants on each side of the wager. This allows a bookmaker to act as a market maker by accepting wagers on both sides of the spread. The bookmaker charges a commission, or vigorish, and acts as the counterparty for each participant. As long as the total amount wagered on each side is roughly equal, the bookmaker is unconcerned with the actual outcome; profits instead come from the commissions.
Total – also widely referred to as the over/under is the predicted number of points oddsmakers believe will be scored in the game by both teams combined. The concept is simple – handicap how each team stacks up against each other on offense and defense and predict whether there will lots of scoring or not much. In totals betting, you are predicting whether the combined total score will be more than or less than the total.
