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.
NFL games are popular moneyline games because the specific outcomes can sometimes be difficult to predict for casual players.  Moneyline games are also profitable when they win, which is one reason why the NFL is a favorite among sports gamblers.  An example of a money line is: New York Giants (-120) vs. New Orleans Saints (+130).  In this game, a bet of $120 on the Giants is necessary to win $100, while a bet of $100 would win $130 in the case of a Saints win.  The team with the minus sign is the favorite and indicates how much a player must put down in order to win $100.  The team with the plus sign is the underdog and indicates how much a player would win for a bet of $100.
If your sports betting experience consists mostly of office pools during March Madness or a casual wager between you and a friend while you watch the Super Bowl, the transition to serious sports betting means learning how to read betting lines. The biggest difference between making the kind of casual bets mentioned above and placing wagers with online sportsbooks or at brick-and-mortar bookshops is the use of sports betting lines. Casual wagers usually involve each person in the bet picking one team to win, then wagering an equal amount, say $20 or $30. Professional bookmakers, online sports betting exchanges, and sports betting facilities in casinos have a more complex system for offering wagers on sporting events, in part to ensure profit on the part of the book, and in part to present a standardized representation of odds.
Typically hockey is not a popular sport when it comes to point-spread betting because most games are decided by only a goal or two. Sports like football and basketball are better for point-spread betting mainly because they are higher scoring sports. However, Proline does offer NHL point-spread betting and it can get confusing so let’s take a look at how it works.

The punter usually receives all dividends and other corporate adjustments in the financing charge each night. For example, suppose Lloyds Bank goes ex-dividend with dividend of 23.5p. The bettor receives that amount. The exact amount received varies depending on the rules and policies of the spread betting company, and the taxes that are normally charged in the home tax country of the shares.

For beginning sports gamblers, moneylines (sometimes called money lines or American odds) can be confusing. Unlike point spreads, which are concerned with who wins and by how much, a moneyline is solely dependent upon who wins. Moneylines are used most commonly in low-scoring games like baseball or hockey, but they may also be used in boxing and other sports.
When betting the point spread, there is almost always a winner and a loser. However, in some instances sportsbook decide to put out a whole number such as -3 for bettors to bet on. If the final score ends with a differential of three points - no matter who wins - the bet is considered a "push" and all money is refunded to both sides since neither team covered the spread.
For example, let’s say that two players are playing a tennis match and one player is +250. You think that this player has a MUCH better chance than that but still is an underdog. Most people would tell you that you are crazy to make a bet on someone that you think is going to lose. The thing is, though, underdogs do win and if you’re getting paid more than you should when they do, you’re going to be profitable. Here’s a simple math breakdown.
Bookmakers use odds to even out the bets, getting gamblers to wager on both sides of the line by leveling the playing field. Although there is overall parity in the NFL, there are teams that are haves and others that are have-nots. Indianapolis is still superior to Cincinnati but when they play each other the bookies have to get about half of the bettors to put cash on the Bengals. This covers the sportsbooks ensuring they’ll make a decent amount of cash on just about every game.

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).
The number-one key to success here (as it is with any type of sports bet) is understanding what value is and knowing when and how to take advantage of it. Value, in a nutshell, is finding sports bets that are paying you at a better rate than you think they should. If you place enough of these bets to overcome variance, you’re going to be a long-term winner.
Since draws are more common in soccer, most soccer markets offer 3-way spreads. When making a Soccer Spread wager, the team you wager on must cover/beat the goal spread. This means that the favored team must win by more than the outlined number of goals or the underdog will receive that number of goals as a head start. If you wager on the spread draw, you are wagering that the game will end in a draw when the spread value is applied to home team. (The team displayed first)
In football the money line is often a popular choice for bettors who have been burned by last-second scoring that actually had no actual affect on the outcome of the game. With the money line you just have to hope your team wins rather than cover a point spread. Of course, the one downside is having to risk more money to return the same amount that a point spread bet would net you.

An If Bet is another type of bet that is a favorite among bettors. An If Bet is similar to a parlay bet, however not quite the same. These types of bets can only be made after the original bet is made and won. An If Bet gives you the chance to bet on more than one game if the previous bet before has come out victorious. For instance, if you place a bet on the original game and it's a winner, an If Bet would require the total payout to be risked on the next bet. If an If Bet is lost, the total payout is subtracted from the last wager you have made.
Moneyline parlays are growing in popularity. A parlay is a single wager that is comprised of multiple results. The payout for a parlay is greater than an individual wager on each player or game. Underdog moneyline parlays are becoming popular because the payouts can be very large. Moneyline parlays are becoming popular because of the perceived ease of choosing multiple favorites to win. Choosing one winner is difficult and multiple winners at the same time is even more difficult.
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.
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.
Remember with bets like this you can still be profitable by betting several options. Let's say you think Chelsea is going to win, but you also think Manchester United, Liverpool, and Everton also have a shot. If you were to place a $100 wager on all four of these teams, you would still turn a profit! Let's pretend you did this and say that your last pick Everton pulls it off and wins the regular season according to the sportsbook. Remember, they don't have actually to win, they just need to be on top after the sportsbook makes the point spread/handicap adjustments to the final rankings.
The odds listed are a primary way of gauging the play in the game. There are hundreds of mismatches every single year and the leveling of the playing field has been very helpful in resolving that particular problem. With the use of odds, bookies are able to acquire an equal number of wagers on each team, which assures them that they get money regardless of who wins.
Essentially, a moneyline bet is a bet on which team is going to win the game. There is no point spread or other handicap for either team, so if you pick a team and it scores more points than the other team then you win. Obviously there has to be a catch, though, or the bet would be way too simple. The sportsbooks balance their risk by setting different prices on each team. You win a smaller amount than you bet if you pick the favorite, and you generally win more than you bet if you pick the underdog. The stronger the favorite the less you will win, and vice versa.
Another popular form of golf betting involves matchup propositions, in which two golfers are paired against each other in a head-to-head wager, with a betting line on each golfer set by the oddsmaker. The golfer with the better (lower) score wins the matchup. (If one golfer continues play in the tournament after his opponent misses the cut, the golfer who continues play wins the matchup.)
