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.
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.
The team that has the minus sign, which is the favorite, has points deducted from its final score, while the dog, with the plus sign, has points added. The favorite must beat the spread, which means they have to win by more than the negative number to pay off. The underdog pays off in two instances—if they win outright or if they lose by less than the spread.
If you'd rather not deal with point spreads, you can do a "Money Line" wager, which is whether the team/player you bet on wins or loses. You will see "Hawaii Tech +150 or Alaska Tech -140". This means if you bet on Hawaii Tech, if you bet $100, you would profit $150 (returns $250), while to win $100 on Alaska Tech, you must put up $140. Those ratios work whether you're betting $100, $10, or any other multiple of money.
For all the talk of new forms of wagering, the good old point spread remains the bet of choice for most NFL fans. Also known as the line or spread, the myth is that Las Vegas sets the point spread as its predicted margin of victory for one team. In reality, it's a number chosen by oddsmakers that will encourage an equal number of people to wager on the underdog as on the favorite. The negative value (-3.5) indicates that team is favored by 3.5 points. The positive value (+3.5) indicates that team is the underdog by 3.5 points. Betting on the favorite means the team must win by at least four points to cover the point spread. The underdog team can lose by three points and still cover the spread. You will also notice a moneyline value associated with the point spread (such as -3.5, -115). This indicates how much you must risk in order to book the bet (also known as the vig or juice). It means you have to risk $115 to win $100. The underdog may see a value such as +3.5, +105. This means you risk $100 to win $105 if your team covers the spread. The spread is not a static number, so you will notice line moves during the week. Team A may be favored by 3 points on Tuesday and by 4.5 points on Friday. This indicates more people are betting on them, so Las Vegas increases the underdog value hoping to encourage more wagers on the underdog.
The 3-digit numbers to the far right are the listed prices for these bets.  This is also called the odds, vig, or juice.  An easy way to think of it is the amount you must risk to win $100 on this wager.  In our example, -110 means you must risk $110 if you want to win $100.  -110 is pretty standard, but you will find different options.  We will cover those in more depth when we talk about money lines.  The price of the bet has no impact on which team is favored.  Only the plus or minus on the point spread matters.  This is handled differently when you bet strictly on the moneyline.
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.
"Since pre-filing the bill in the fall, I spoke on the Senate floor to stress the importance of being ready to move forward when the court handed down its ruling and use the benefit of having this new revenue to fund our pension systems and education," Carroll said in a statement on Monday. "We could have been in front of this issue had we acted in the last session."
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.
As an illustration, let's look at Super Bowl futures. Sports books list each NFL team with corresponding odds to win the Super Bowl. For example, the Ravens may be 5-1, the Redskins 12-1, the Cardinals 100-1, etc. If you place $10 on the Redskins and they go on to win the Super Bowl, you collect $120 plus your $10 back for a total payoff of $130. It does not matter whether your team covers the point spread in the Super Bowl. For the purposes of future book betting, the team has to win only the Super Bowl.
For those that live outside the United States, this may look even more strange since -110 is in American odds format. In Decimal odds, which is common in Europe, -110 translates to 1.91 odds. I'm not going to dive into Decimal odds (or other formats) since this article is about American odds, but the Decimal system is pretty straightforward. The odds listed represent a bettor's total return for a winning wager as you simply multiply the odds by the amount you wish to risk. If someone risks $100 at 1.91 odds and win, they receive $91 plus their initial $100 risked ($91 + $100 = $191).
Okay, so the other betting option available to you is the total or ‘Over/Under.’ You can choose to bet that the total points between the two teams will either be greater (OVER) or less than (UNDER) the projected total. Again, if you bet either way and the game ends up being 20-21, for a total of 41 points, then you will receive a refund of your wager amount.
Many of the leading gambling bookmakers from the 1930s to the 1960s got their start during the prohibition era of the 1920s. 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.[4]
As always, beware of sites offering paid or free NFL betting picks in connection with a varying unit betting system. If you are using their pro football betting picks to gamble on NFL football games, you might consider that some of these sites are providing money tips which are likely to drain your NFL sportsbook account. Earning gambling profits long term takes discipline to know there is always another game to bet on. Most free sports pick sites don't understand that it requires more than winning football predictions to earn a living betting on sports. So for anyone living in an area where NFL gambling is legal, keep in mind that relying on "bet the house" free NFL picks could seriously reduce your NFL betting success.
