There is no such thing as a half point in sports, but there is in sports betting! The half point ensures that a side will win and that the match will not end in a push, where the spread equals the actual difference in points between the two teams. In a push all bettors get their money back, which is no good for the oddsmaker! Half points also give oddsmakers more control over lines, allowing them to set more specific values.
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.
Apply the spread. In point-spread betting, the actual final score of the game is only the starting point. Say Chicago beats Detroit 24-17. Because Chicago was the favorite, you subtract the point spread from its final score. That's the purpose of the minus sign in the spread. The spread was 6, so you take 6 points away from Chicago's point total, giving you an "adjusted" score of Chicago 18, Detroit 17. If you'd bet on Chicago, you'd have won the bet. Now, say Chicago won the game 20-17. Subtracting the 6 points from Chicago's total gives you a final score of Detroit 17, Chicago 14. If you'd bet on Chicago, you'd have lost.
--Fractional odds are most commonly found in racing. A 10/1 payout should be read "$10 paid for every $1 wagered." When the bigger number is on the left, you will find that bet is normally an underdog in the race. Also note, however, that in case such as "Who will win the Super Bowl in the NFL?" you will see all the teams listed as "underdogs"… i.e. paying at least 2/1 (some up to 300/1 or more).
The one variance you might come across in any pointspread listing is the commission owed on a bet. Instead of moving the actual spread for a game, some books will try and direct money one way or the other by adjusting the juice. For example, if there was a (-120) next to the listed pointspread, you would now owe $120 on a losing $100 bet. Sometimes a book will reduce or eliminate the juice all together to move money towards a particular side of a matchup. In this case, you might see (-105) or (+100) next to the pointspread to signify the reduced or zero commission for that bet.
Once you have selected the appropriate sport, league and game, the betting options appear. A betting option is, for example, the winner of a game, how many goals will fall or how many fouls, penalties, corners and free kicks there will be. For football matches in the first leagues, there are usually around 40,000 different betting options available for almost every country. The large offer may seem deterrent, but the betting providers solve the problem with a very good overview as well as a function to find the desired betting option quickly and easily. There's a odds on every betting option. This number indicates how likely a betting option is. If the odds are high, the profit margin is also high, but the probability of the event occurring is very low. An example of this would be if a third division team won against a first division team. If the rate is low, the event is very likely. So in terms of the example that the favorite will win the game. The process of a bet reads longer than it is. After the first bets, the process has already turned into flesh and blood and you can place betting options every minute. Of course, only if you have informed yourself about sports and betting in detail beforehand, because this is the only way to make sports betting with responsibility and a good chance of success possible.

In-play betting. In-play betting is a fairly new feature offered by some online sports books that enables bettors to place new bets while a sporting event is in progress. In-play betting first appeared towards the end of the 1990s when some bookmakers would take bets over the telephone whilst a sports event was in progress, and has now evolved into a popular online service in many countries. The introduction of in-play betting has allowed bookmakers to increase the number of markets available to bet on during sports events, and gamblers are able to place bets based on many different types of in-game activity during the matches. For example, in football matches, it is possible to bet in on in-play markets including the match result, half-time score, number of goals scored in the first or second half of the game, the number of yellow cards during the match, and the name of the goal scorers.  The availability of a particular sport and in-play markets varies from bookmaker to bookmaker. In-play sports betting has structural characteristics that have changed the mechanics of gambling for sports bettors, as they are now able to place a larger number of bets during a single sports game (as opposed to a single bet on who is going to win). One of the most important differences between being able to place an in-running sports bet opposed to a pre-match bet is that the nature of the market has been turned what was previously a discontinuous form of gambling into a continuous one. The gambling study literature has suggested that in-play sports betting may offer more of a risk to problem gamblers because it allows the option for high-speed continuous betting and requires rapid and impulsive decisions in the absence of time for reflection. There are three different types of in-play sports betting products(cash out, Edit my Acca, and Edit my Bet).
With the over/under or total, bets are being made on what the total score may be. In our example which features two solid defenses and good offenses, the total might be around 41. If OSU scores 24 and Wisconsin 20, the total would be 44 or over the 41. If the Buckeyes scored 21 and the Badgers 14, then the total would be 35 so the under would win. Once again sometimes, if the total is a whole number, the result may be a push. That results in all bets simply being returned.
Let’s start with the basics: what do sports bettors mean when they talk about a ‘line?’ The word line, in the language of a sportsbook, can refer to either the odds and/or a point spread in any sports contest. Let’s take a look at an imaginary line the way you’d read it off the board sitting in a Vegas sports betting lounge or on the screen at your online book. Let’s imagine a game between the New York Giants and the Dallas Cowboys. Your book’s NFL betting line might look something like this:
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.
Here you can see that the Rams are +3.5, while the Cowboys are -3.5. So for this example the Cowboys are 3.5 point favorites, while the Rams are underdogs of 3.5 points. If you were to bet on St Louis you would need them to lose by 3 or fewer points or just win the game outright. If you were to bet on Dallas you would need the Cowboys to win by 4 or more points.
