Technically, probability should always be a number between 0 and 1. It's often expressed as a percentage though, which makes things easier for the purposes of betting. 0.7059 converted into a percentage (i.e. multiplied by 100) gives us 70.59%. What this means is that the odds suggest the Celtics have a 70.59% chance of winning. If we believe the Celtics have an even greater chance of winning, then we should back them at odds of -240.
The last number in the top two rows of our sports line example is known as the money line. If you’re not interested in betting on the point spread, you can wager on a team to win outright. The plus sign next to the underdog (in our case, the Giants) indicates how much money you’ll earn for every $100 you bet on the money line. Conversely, the minus sign next to the favorite’s line tells you how much you have to wager in order to win $100. In our example, a $100 wager on the Giants earns you $300 should they pull off the upset, while a bet of $405 on the Cowboys will net you an extra $100. Representing odds in units of $100 makes placing different size bets easy; if you want to bet $10 on the Giants, you stand to earn $30 if they win, while a $40.50 bet on the Cowboys will net you an additional $10.
At a site that offers a free play bonus, you'd bet $100 free play on the Grizzlies at +210. At another site, where you have a cash balance, you bet $150 cash on the Celtics at -240. If the Grizzlies won, you'd win $210 cash from your free play but lose your $150 cash. That's a profit of $60. If the Celtics won, you'd win $62.51 from your cash bet and lose only your free play credit. That's a profit of $62.51
Point spread and handicap betting are one of the most popular forms of sports bets that you can place. The reason we say "one" of the most popular forms instead of "two" is that these bets are effectively the same thing. These bets are a lot of fun because they allow you to root for teams that you still think are going to lose. With point spread and handicap bets, the team you're betting on can lose the game, and you can still win your bet. In contrast, the team you are betting on can win the game, and you can still lose your bet. Now that we've thoroughly confused you let's build up your knowledge, so you're an expert on the bet type. This is like sports betting boot camp; we confuse you and break you down and then build you back up as a betting machine!
If an intentional foul causes an injury and the injury results in the fight being stopped in a later round: (i) the injured boxer will be deemed to have won by technical decision if he is ahead on the scorecards and (ii) the fight will result in a 'technical draw' if the injured boxer is behind or even on the scorecards (and, for settlement purposes, the result of the fight will be deemed to be a draw).
By far the largest part of the official market in the UK concerns financial instruments; the leading spread-betting companies make most of their revenues from financial markets, their sports operations being much less significant. Financial spread betting in the United Kingdom closely resembles the futures and options markets, the major differences being
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.
A Parlay is a wager which combines several legs in a wager where the winnings from each selection roll onto the next. For a Parlay to be successful, all individual legs in the Parlay need to be winning selections. In the event of a tie in one of your selections in a parlay, the parlay is reduced to the next lowest number of teams. For example, if you have a 4 team parlay and one of the selections is a tie (only on 2 way markets), the leg would be considered a "push". In this instance, the 4 team parlay would then become a 3 team parlay and would be settled at reduced odds to reflect a winning 3 team parlay.
The key to successful betting lies in quality and not quantity. Your overall chances of winning are much greater if you pick your spots carefully, and only bet when you find real value. There isn't a huge number of NFL games each week, but there's enough that it's simply not realistic to think you can handicap them all. And if you're also betting on college games then this is even more of an issue.
We go in depth on this in the advanced guide on understanding value that we referenced earlier, but we will give you a brief intro on it here. If you’re able to calculate the percentage chance that you have to win in order to break even, and you can figure out the percentage chance that you think you’re going to win the bet, you can figure out very quickly if there is value.
Let's say you decide to bet $100 on Liverpool, and they lose the game by two goals. You would push on the first half of your bet and win the second half of your bet. You would receive your $50 back for the push and $43.48 in profit on your second bet. Basically, the sportsbook would hand you back $143.48 total, which would include $50 for the push, $50 for your original bet, and $43.48 for the push.
Before we had the options of wagering on future bets, parlays, teasers, alternative lines, Asian lines, prop bets and each-way, there was one betting option that reigned supreme. It was the money line bet. From a non-gambling perspective, winning a game in any sports will make a team happy. However, depending on the score, that win may not please bettors. That’s because the point spread betting option has taken over as the popular option, leaving the money line far behind. If you are the kind of person who bets on your favorite team each and every game, this is the bet for you. There is nothing worse than watching your team win the game, but lose you money by not covering the point spread.
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.
As an illustration, let's look at Super Bowl futures. Sports books list each NFL team with corresponding odds to win the Super Bowl. For example, the Ravens may be 5-1, the Redskins 12-1, the Cardinals 100-1, etc. If you place $10 on the Redskins and they go on to win the Super Bowl, you collect $120 plus your $10 back for a total payoff of $130. It does not matter whether your team covers the point spread in the Super Bowl. For the purposes of future book betting, the team has to win only the Super Bowl.
