When sharp bettors place heavy wagers, sportsbooks take this as a signal that these bettors have valuable information or insights. For example, if the majority of bettors back a popular team, the sportsbook may adjust the line to make the less popular team more attractive. This format keeps games thrilling until the final whistle, adding intensity even to potential blowouts. Bets in sports betting come in various forms, generally focused on picking winners, predicting score margins, or anticipating total points.
Fractional odds can be a bit trickier to calculate quickly, but they’re favored by many bettors for how clearly they represent the risk-reward ratio. If you bet $10 at 7/2, you’d get $35 in profit plus your initial $10 back, totaling $45. They’re expressed as fractions, like 5/1 or 7/2, showing the ratio of profit to the original stake.
We also compare prices on boxing and MMA, where big fights are added as soon as bookmakers publish odds, on esports and on rugby union, rugby league, baseball, volleyball, Aussie rules and many more. Our tennis odds page compares the prices on every match of the day, next to past results and the odds they closed at. In tennis we follow the ATP and WTA tours every week, the Challenger and ITF events in between and the four Grand Slams, from the Australian Open to Wimbledon and the US Open.
Decimal odds make comparing bets straightforward because you’re seeing the total return value in one number. Higher numbers indicate higher potential payouts, while lower numbers signify favorites and lower returns relative to the stake. The key to understanding decimal odds is that they directly represent the total return.
The total of these three percentages is 100%, thus representing a fair ‘book’. In a 3-horse race, for example, the true probabilities of each of the horse racing betting not on gamstop horses winning based on their relative abilities may be 50%, 40% and 10%. In formulating the odds to display the bookmaker will have included a profit margin which effectively means that the payout to a successful bettor is less than that represented by the true chance of the event occurring.
In gambling, the odds on display do not represent the true chances (as imagined by the bookmaker) that the event will or will not occur, but are the amount that the bookmaker will pay out on a winning bet, together with the required stake. In most cases, the favorite will have negative moneyline odds (less payoff for a safer bet) and the underdog will have positive moneyline odds (more payoff for a risky bet). A “moneyline” wager refers to odds on the straight-up outcome of a game with no consideration to a point spread. For example, 6/5 fractional odds (also described as “1.2” or “6 to 5”) are the same as 11/5 decimal odds (also described as 2.2 or “11 for 5). A variation of fractional odds is known as Hong Kong odds. However, not all fractional odds are traditionally read using the lowest common denominator (i.e. simplifying the fraction when possible).
Our basketball odds page brings together the games of the day, while results and standings go back several seasons. On the blocked odds page, you will be able to see matches or markets that online bookmakers are no longer offering odds for, which can signal a change in the market before other operators react to it. It is where the hot odds of the day show up first, and you can filter it by the last hour, 12 hours or 24 hours, by the percentage of bookies cutting their price and by market. The dropping odds page shows when the odds on a team, player or market have dropped before the start of a match.
Some bets involve combining multiple outcomes for higher rewards, while others target specific in-game events or achievements. Once you’re familiar with the basic math, fractional odds become an easy way to see potential profits relative to the stake. They’re especially popular in horse racing, where bettors often look for value in underdog picks or assess returns more precisely using this format.
