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.
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.

NFL moneyline betting continues to gain popularity as many begin to understand the value of moneyline bets, especially in betting the underdogs. In this type of bet, there is no spread to beat, your team needs only to win the game “straight up” (SU), and there is no requirement for how many points they need to win by. The juice is the only number you really have to pay attention to with moneyline, where the negative value indicates the favorite (-140) and a positive one means underdog (+120).

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.
The biggest advantage of the moneyline for the NBA is that your team doesn't have to overcome the point spread for you to win your game. If your handicapping leads you to believe that one team is likely to win but you can be less certain that they will win by as much as the point spread then the moneyline may be attractive. You are sacrificing some potential return because the moneyline won't pay as much for the favorite as the point spread will, but it's obviously better to make a small profit than it is to lose a bet. This is particularly attractive in basketball because the favorites can often face large point spreads and teams can win comfortably and effectively without covering the spread.
Placing a point spread bet means gambling on how much a team will win or lose by. In our above example, the Cowboys are the favorite. How do we know that? The minus symbol in front of the point spread indicates that the bookmaker thinks the final score will have Dallas winning by 7.5 points or more. The underdog, in our example that’s the New York Giants, will always be indicated with a plus sign. If you wager on the Cowboys on the point spread, America’s Team will have to win by at least 8 points for your wager to pay off. Should the Cowboys win by less than 8 points, your bet is lost.
“Limitations. Subject to the foregoing, and subject to all of the terms and conditions of this Compact, the Tribe shall establish, at its discretion, by tribal law, such limitations as it deems appropriate on the amount and type of Class III Gaming conducted, the location of Class III Gaming on Indian Lands, the hours and days of operation, and betting and pot limits, applicable to such gaming.”
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.

The basic principle of point spreads and totals is that you have roughly a 50% chance of winning, so technically a "fair" return on these types of wagers should be equal to the amount staked. However, they are usually priced up by bookmakers at odds of -110 (1.91 in decimal odds format, 10/11 in fractional odds format), which means for every $110 staked you stand to win $100. You don't have to stake as much as $110 of course, but the point is that a successful wager will only return 90% of the amount staked (plus the initial stake of course).

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.

Anybody who wagers on the 49ers would need them to win by 7 points or more for a winning bet. Those betting on the Rams (+6.5) would need them to lose by 6 points or less (or win) for a winning wager. It's also worth mentioning that a half point is used in many point spreads (such as the -6.5/+6.5) to prevent pushes because no team can score half a point.

Baseball. It's America's pastime. A game that prides itself on being perfect in every way imagina-ble. It's almost as much an individual sport as it is a team sport when you consider that in every game and in every inning, a pitcher faces one batter at a time, and whichever player wins that battle brings their team one step closer to victory.

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.
Once you understand all the fundamentals of football betting, and have an account with a suitable gambling site, you're pretty much ready to go. There's still a lot more you need to know, but most of this can be learned as you go along. Indeed, learning as you go along is the best approach. Trying to become an expert before actually getting started is a futile exercise, as so much of what's involved only really starts to make sense once you have some real experience to draw on.
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]
Straight bet - Amid all the fancy and lucrative-looking bets that are available, never lose sight of the value in a standard straight bet. You probably should learn and practice this bet often before learning any others, and it should be noted that people who bet for a living or a large portion of their income place straight bets almost exclusively.
Sports betting would be easy — or maybe just easier — if all that was required was to correctly pick the winning team. Gambling institutions, sportsbooks and bookies fall back on point spreads to make the process a little more difficult and to create the ultimate wagering challenge. You'll need a solid understanding of the point spread system if you hope to have a profitable season.

If bettors were quick to jump on the Atlanta line at +4.5 when it first came out, they would have a distinct advantage over those who waited closer to kick off and were stuck with +2.5. The opposite holds true for Carolina. Bettors that were quick to pull the trigger are now laying two more points than they would if they were patient and saw the line movement before making their move.

"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."
While most football fans have seen a point spread before, not everyone understands how they work. There’s a common misconception that the oddsmakers are trying to outsmart their customers by posting the spread and getting people to bet on the wrong side. At the same time, many bettors think that their goal is to “beat the bookie.” This is false; as mentioned, the sportsbook is incentivized to keep the action on either team as balanced as possible, in order to limit exposure.
Over/Under means the odds-makers picked the most likely total combined score of both teams. For example in an NFL game with the Jaguars vs Dallas the over/under is 37. You can either bet on either “over” or “under”. Over, is if the two scores added up at the end, total to over 37. Under is if when you add them together, they’re less than 37. If the total is 37, it’s a tie, or “push” again.
If you see the point spread move, let’s say from -9 on Tuesday to -10.5 on Friday, this is known as a line move. It occurs when there is a surplus of bettors wagering on the same side of the game and sportsbooks move the line to balance the action. That means encouraging more people to bet the other way by making the line more appealing. This reduces risk for the sportsbook, who wants to have an equal handle on each team.
