When unforeseen events occur such as weather, power outages, or any other unanticipated event once the game has started, many people wonder how that will affect the wager. If an event has not started, all wagers should have no action and be refunded. But if the event has started and is interrupted and not completed it gets a little more complicated. The following will examine the special rules for each sport and give you a better idea of what to expect should the event not be completed on the same night. Always check with your book to know any special rules that may apply but according to the letter of the law: the following is how each event should be interpreted.
In general, the betting public tends to gravitate towards favorites when betting the games regardless of the actual pointspread. This is especially true with high-profile teams such as Dallas and Green Bay in the NFL and Golden State and Cleveland in the NBA. The sportsbooks are well aware of this phenomenon and often times they will adjust the betting spreads accordingly. This, in turn, actually adds some value to the underdog when you consider that a pointspread is nothing more than a handicapping tool that is designed to even out the match.
The Patriots are set to take on the Rams in the greatest show on turf and money has been flowing into both sides of the Super Bowl 53 point spread. The Patriots are -3 for SB LIII according to most legal online sportsbooks but some have them listed only at -2.5. The Rams and Patriots are both offensive minded, and capable of scoring quickly; therefore, the winner will likely be whoever scores last in the game (-180). There is still no discussion of whether the roof will be open or closed at Mercedes-Benz Stadium in Atlanta, so weather may or may not play a factor here. Either way, make sure to get in your bet on the spread for Super Bowl 53, whether you choose the Patriots or Rams, before the 6:30 EST kickoff on Sunday, February 3rd.
Another form of futures betting involves the over/under on the number of games a particular team will win in the regular season. This type of wager is typically found on pro football and major league baseball, and sometimes on pro basketball. For example, the over/under on the Yankees may be 93 wins. If the Yankees go on to win 94 or more games, the "over" is a winner. If they win 92 or fewer games, the "under" is a winner. If they win exactly 93, the bet is a push and tickets are refunded.
Let’s say that the Mavericks and the Magic are playing in an upcoming game, and both teams are equal counterparts. Let’s say that the odds for that game are as follows. You will never see these odds, though, because in this example, the sportsbook is not set to make any money if they achieve their goal of getting money on both sides of the bet. But we need to look at it for you to better understand things.

Let's use this formula to calculate the implied probability of the Celtics winning their game against the Grizzlies. We know the odds are -240, which means we'd have to risk $240 for a total potential return of $340 (the initial stake plus the $100 winnings). So the calculation here is $240 divided by $340. This gives us an implied probability of 0.7059.

What may look like a jumble of words, numbers, and punctuation is actually a precise and easy-to-read breakdown of the various odds and point spread details your book is offering. Here is a breakdown of each unit of information given above. Once you understand each part of the jumbled details above, you’ll be able to read a sports betting line with confidence.
Armed with the knowledge of how to remove vig, it's now possible to prevent yourself from making the same mistakes that the majority of bettors make. Most bettors understand the importance of line shopping (i.e. comparing the lines and odds at different bookmakers and betting sites). However, if they fail to also understand how moneylines and vig work, then they're probably going to make wagers where they think there's positive expected value (+EV), even though there's not.
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.
With moneyline bets, there is no point spread to manipulate. Instead, the sportsbook will alter the payouts you’ll receive for a correct pick. The bigger the favorite, the less you’ll get paid. The bigger the underdog, the more you’ll get paid for a correct wager. This line will fluctuate as the sportsbook needs it to in order to encourage or discourage bets on either side.

This may sound confusing, but spread betting is one of the easiest forms of sports betting offered. It also offers better odds when betting on the favorite team and the normal odds are 10/11 or -110. When one chooses to bet on the underdog that team does not have to win, they just have to cover the spread. Spread betting is pretty simple and it allows punters to enjoy an exciting form of betting that can lead to some significant wins.


This is a very common occurrence in sports betting and sportsbooks have the full right to shift the spread or odds for any given match prior to it starting. Many factors can influence a change of the spread such as injuries, the number of bets coming in for either team or the weather, to name a few. Depending on the timing of placing the bet, the bettor can also have an advantage or a disadvantage depending on which way the spread has shifted.
