How betting odds work: what they are and how to use them

If k is any positive number then X to Y is the same as kX to kY, and similarly if «to» is replaced with «in» or «for». Multiplying these probabilities by 100% gives the percentage. When probability is expressed as a number between 0 and 1, the relationships between probability p and odds are as follows. When Moneyline odds are quoted as a positive number +X, it means that a wager pays X to 100.

The same selection is priced differently by each bookmaker, so comparing bookmaker odds is the simplest way to make sure a winning bet pays out as much as possible.

Similarly, fair betting odds can be expressed as «(1−p)/p to 1», «1/p for 1», «+100(1−p)/p», «−100p/(1−p)», «D−N to N», «D for N», «+100(D−N)/N», or «−100N/(D−N)». In gambling, odds are often given as the ratio of the possible net profit to the possible net loss, and sometimes this is called fractional odds. 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.

In probability theory and statistics, odds and similar ratios may be more natural or more convenient than probabilities. Odds can also be expressed as a number, by dividing the terms in the ratio—in this case it is unique (different fractions best betting sites not on gamstop can represent the same rational number). For example, «odds of a weekend are 2 to 5», while «chances of a weekend are 2 in 7». Implied by this definition is the fact that the probability of an event is given by the ratio of favourable outcomes to the total number of possible outcomes.

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). In either case, having won, the bettor always receives the original stake back too; so if the odds are 4/1 the bettor receives a total of £500 (£400 plus the original £100).

These bets can cover anything from team milestones to individual performances, making games more interactive and fun. Futures keep you invested throughout the season, adding suspense as teams rise or fall and turning each game into a step toward your bigger prediction. For instance, if the line is 220.5 in an NBA game, you’d bet on whether the teams’ combined score will be over 220 or under 220.5.
