Many novice bettors fail to understand the impact of home advantage when wagering on sport events. When looking at the board for potential wagers, these bettors tend to get excited and bet on lots of superior teams favored on the road against weaker opponents. The betting market is so much more advanced than this, and for the most part point spreads are always going to be 50/50 propositions.
Since more people wager on football than any other sports it’s usually the easiest game to figure out how to bet. If you don’t know what to do, you can probably ask anyone in the sports book for instructions. The people visiting the casino might not know everything but they can give you the basics. Here’s a fairly thorough look at the different ways you can wager on football in Las Vegas.
To show how this can be exploited, take a point spread of -8.5 at odds of -110. This is a 50/50 proposition. Let's assume you've purchased enough points to move the spread to -6.5 at odds of -150. Now, you'd win instead of lose 6.24% of the time they win by 8, and 6.59% of the time they win by 7. Add these together with the 50% from the original proposition, and we get 62.83%.
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.
There are many ways that you can bet on football and I will go over all of the different options below.  The first and most common bet is the straight bet, which simply means the team wagered on must win by the point spread given at the time of the wager.  Most of the time the odds on a straight bet is -110, which means for every $110 bet, you win a $100 back.  An example of a straight bet is if the team you bet on is a 6 point (-6) favorite, also known as giving up 6 points.  Then in order for you to win, the team taken in the wager must win by more than 6 points in order to collect your winnings.  If they win by 6, then this will be called a push and your original bet will be refunded to you.  You can also bet on the totals, which is also known as the over/under bet.  The totals bet is The combined score of both teams for games wagered on, all totals pay out at -110, which is $110 dollar bet makes you $100, no matter if you bet on the over or the under.  If the total score equals the line, then the bet is a push and you get your original bet back.  Another type of bet is the money line bet.  This bet is simply that team wagered on just has to win the game.  The odds on these games vary depending on the disparity between the favorite and the underdog.  You obviously will win more betting on the underdog; however there is a reason why these bets pay more because the odds of the underdog winning are decreased.  Although betting the moneyline can sometimes return a big sum, it is wise to know that the bookmakers hold percentage is much larger than a typical straight bet on the side or total of a game.  A classic straight wager on the point spread is almost always dealt at -110 on both sides which is 20 cents of vigorish.  Compare that to a double digit favorite in college football with a money line of -600/+450 and you can see the extra 130 cents of vig added in.
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.
A listed odd with a – sign in front of it, such as the -140 in our example above, shows us how much money you would need to wager in order to win $100. So using the -140, this would show us that you would need to bet $140 in order to win $100 in profits. You can easily substitute the $100 bet for a $10 bet by moving the decimal place over one spot, showing us that you would need to wager $14 in order to win $10 in profits.

Round robin betting is a creative type of parlay betting that requires making multiple parlay bets at once. Deriving its name from round robin tournaments—where each team in the tournament plays against each other at least once—this type of betting is when you have a number of betting lines (moneyline bets, spread bets, totals bet, etc.) you want to parlay.
If you’re going to bet on college football odds, it’s essential to understand each aspect of odds listing, including the rotation number, point spread, moneyline and over/under. You’ll often find different terms used to describe these with the rotation number called the number, point spread shortened to spread, moneyline to line and over/under simply called the total. These are all lumped together under the term odds.
The point spread is a handicap placed on one team for betting purposes only, it has no place in the game itself. It's designed to give both teams an equal chance at winning in the context of wagers. Think of it this way: If last season's Super Bowl champion was playing a basement-dweller team that hadn't won a game all year, that's a shoo-in bet. Of course, you're going to take the Super Bowl champs, and in all likelihood, you're going to win. What's the fun in that? Even your bragging rights would be next to nil.

Generally, the number next to the spread is “-110”. This is what’s known as the juice, vig or odds. The juice is a fraction of the wager taken from the bettor if the bet wins. In this instance, a winning wager of $110 will yield a profit of $100.The example above demonstrates that, although Indianapolis won the contest, Tennessee covered the spread by losing by less than nine points. An important aspect of sports betting is capturing the best line possible. A great way to achieve this is by shopping for the best line.

Who doesn’t love a good old-fashioned NFL spread? Not only does the point spread remain the king when it comes to wagering on pro football, it is a favorite among pro sports bettors and beginners alike. Also known as the line or spread and as betting “sides,” a common misconception is that sportsbooks set the spread as a predicted margin of victory. It’s actually the number oddsmakers predict would be a good balance between people who want to bet the underdog and those who want to bet the favorite.
