Without a points handicap, it would not make sense to pay both sides of a wager the same amount when it's clear that not all teams are on equal footing. In fact, it is entirely possible for a team to lose the game in real-life but still win a bet if they only lose by less than a set number of points. Vice versa, a team can win a game, but lose the wager if they do not win by more points than what was predicted.
Settlement of bets which make reference to terms such as "decisive goal" will be settled based on the scorer of the goal that at the end of the match/tie,) proves to be the one that has produced an unassailable lead, following which any further goals would prove to be irrelevant towards the final outcome. For a bet to be settled as "YES", the listed player's team must be declared the winner of that particular match or progressing to the next round or winning the competition. Goals scored in Regular Time and Extra Time count but Penalty Shoot outs do not.

Point spreads are determined by football 'experts' to even the playing field between two teams. Normally one team will be favored to win over another team. These 'experts' determine the number of points that one team will beat another team by. For example, Chicago is favored to beat Minnesota by 10 points. On the web site it will appear like the following:

It is a very good idea to shop around to find the best line when you are betting on sports. Books may offer slightly different lines, and you might be able to gain a point or half a point in your favor on certain markets. Consider an NBA game between the Heat and the Lakers – one firm has the Heat 9.5 point favorites and another have the Heat as 8.5 point favorites. You back the Heat with the second firm and they win by exactly nine points. Here you’ve gone from a loss to a win simply by shopping around, and in the long run this will make a big difference to your bottom line.

Identify the type of line you are looking at. All online sports books offer you the chance to have your lines in an "American" or "Money line" version. If I were you, I would use this as my standard. An "American" line uses either a + or - before a number to indicate odds. So a -120 and a +120 are two very different odds on a team… I will explain the differences shortly. Two other less common variations exist: decimal odds and fractional odds.

Let us be clear before we go any further with this strategy tip. If there is value in a bet, go ahead and make it. What we want to talk about, though, are bets where you are risking an abnormally high amount of money to win a very small amount of money. While this is still technically profitable, you might not get enough opportunities to push through the variance and realize your value.

What this means is that in each contest, there is going to be a favorite and an underdog. It’s important to point out that when you look at a moneyline bet, and you see that a team is a favorite or an underdog, this is only in relation to the money that is being bet. While these numbers will usually be in line with which team is the actual favorite and underdog, it could be different. Remember, the betting lines are tweaked so that the sportsbook can get the right amount bet on each side of the contest.

A teaser is a bet that alters the spread in the gambler's favor by a predetermined margin – in American football the teaser margin is often six points. For example, if the line is 3.5 points and bettors want to place a teaser bet on the underdog, they take 9.5 points instead; a teaser bet on the favorite would mean that the gambler takes 2.5 points instead of having to give the 3.5. In return for the additional points, the payout if the gambler wins is less than even money, or the gambler must wager on more than one event and both events must win. In this way it is very similar to a parlay. At some establishments, the "reverse teaser" also exists, which alters the spread against the gambler, who gets paid at more than evens if the bet wins.
The main goal for each sportsbook is to set the best line possible in order to create even action on both sides of the game. In a perfect world, the book would have 50 percent of the handle come in on the favorite and 50 percent of the action come in on the underdog. If this happens, the sportsbook would be guaranteed a profit because of the 10 percent vig they charge on most point spread wagers. When a book has serious one-sided action, they will attempt to counter that by moving the line in the direction that's taking the most money and try to entice bettors into betting on the other side.

You've probably noticed by now that in the first game there are no odds posted in parenthesis to the right of each team. This means that the sportsbook is paying out both bets at the standard odds for a point spread bet of -110. Some sportsbooks will write the -110 in, and some will just leave it blank assuming that you know they will be paying out at the standard odds rate.

Obviously, the first three letters on the top two lines of the three-line package of symbols represents a team in the game you’re wagering on; NYG stands for the New York Giants, while DAL stands for the Dallas Cowboys. The number next to each team’s name is known as the spread or the point spread. Wagers on the point spread are among the most popular sports wagers in the world. The reason this wager is popular is that it doesn’t matter which team wins or loses; what matters is the amount of points the teams score, and whether or not the team you place your money on beats the difference in points (the ‘spread’) or not.
Bets on "Race to X Points / Race to X Goals..." and similar offers refer to the team/participant reaching the earliest particular tally of points. If the offer lists a timeframe (or any other period restriction) it will not include any other points tallied from other parts of the event which are not related to the mentioned time frame. Should the listed score not be reached within the stipulated time frame, all bets will be declared void, unless otherwise stated.
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)
As we did with the underdogs, we need to figure out how much we will profit for each $1 that we wager. For underdogs, we divided the moneyline number by 100. For favorites, it is the exact opposite. We will take 100 and divide it by the money line number. So, for this example, we will take 100 and divide by 155 and get about $0.645 or about $0.65 in profit for every dollar that we bet.

The "Total Points", also known as Goals or Runs, is a 2 selection odds based on the total number of points scored in a game or event by the competitors. The "Total" is set at a specific line with outcomes listed as either Over or Under the listed amount. As with Point Spread/Handicap betting, in those circumstances where the result of the game or event Total point scored is exactly equal to the betting line, then all bets on this offer will be declared void. “Totals” can also be set on any number of predefined occurrences (e.g. goals, points, corners, rebounds, penalty minutes, etc.).

When betting on the favorite, simply divide the negative moneyline by 100 to get a decimal. If you were planning to bet on the Celtics in the above example, this would give you 2.40 (ignore the negative). Now all you have to do is divide your stake by that number in order to see what your potential payouts would be. Let's say you wanted to stake $650. When you divide that number by 2.40, you'd see that your potential payout is $270.83.
You’ll see on the right-hand side of the teams a number with an “o” or a “u” before it. As you may have already gathered, the “o” stands for over and the “u” stands for under. Even though the over is on the Celtics line and the “u” is on the Mavericks line, it does not matter. They’re written that way for organizational sake and not because either bet is connected to either team. Remember, it only matters that the total score of the game is. One team can score all of the points, and you’ll still win your bet.
The optimal situation for bookmakers is to set odds that will attract an equal amount of money on both sides, thus limiting their exposure to any one particular result. To further explain, consider two people make a bet on each side of a game without a bookmaker. Each risks $110, meaning there is $220 to be won. The winner of that bet will receive all $220. However, if he had made that $110 bet through a bookmaker he would have only won $100 because of the vig. In a perfect world if all bookmaker action was balanced, they would be guaranteed a nice profit because of the vig.
Especially in major tournaments, some sports books offer odds on unusual golf propositions, such as the over/under on the winning score, the over/under on the lowest round by any golfer or the over/under on the finishing position by a particular golfer. For example, the over/under on Woods' finishing position may be 3 1/2. If he finishes first, second or third in the tournament, the "under" wins; if he finishes fourth or worse, the "over" tickets cash.
