How Does Odds Change in Betting?

When it comes to betting, the odds always seem to change, but not always in the way you may think they do. The rules and parameters that govern sports betting may seem straightforward, but there are actually a lot of intricacies that come into play when you are placing a wager on a game. This article will try and clear up some of the confusion by explaining exactly how the odds change in betting and how you can utilize that knowledge to your advantage when placing your next wager.

Odds Bias

One of the first concepts you need to understand when it comes to odds and betting is biasing. Bias means “an inclination or preference toward one side or the other” in this case, it means that there is a preference for one outcome over another when it comes to odds. There are a few different types of odds bias, which we will discuss below.


One of the biggest complaints when it comes to sports betting is that the house always seems to favor one team or player over another when it comes down to setting the odds. This is mostly due to the fact that the majority of sports betting takes place in a bookmaker’s office where one person’s interest often conflicts with another’s. It’s a common complaint that the bookie is partial to certain teams or players, and it usually results in the oddsmakers trying to maintain a level of objectivity while still having a stake in the outcome of the game.

Favouritism is a very real concern when it comes to sports betting, and it’s something that every bettors needs to be aware of. The good news is that there are legitimate strategies for combating bookmaker bias, and that’s what this article is going to focus on — explaining the various ways you can exploit odds bias and presenting some solid examples of how doing so can dramatically alter the way you play the game.


One of the best things about betting with pre-set odds is that the books usually try to make their odds as stable as possible. Stability is one of the most important aspects of any good betting option. The less unstable the odds, the better because it reduces the risk of getting drastically wrong that your initial wager. It also makes it easier to predict the outcome of a game since the chances of a major change in the odds are much lower. This is why trying to avoid betting on very low-stability odds is one of the best tips you can get when it comes to placing wagers successfully.

Smaller Wager

One of the most exciting new developments in sports betting is the emergence of the small-group wager. These are essentially pre-set odds bets that are made on the behalf of several individual customers, rather than on the basis of a single bettor’s action. The theory behind the small group wager is to generate a much larger profit margin on a bet than a single person would be able to achieve. What’s more, the bookmaker doesn’t have to factor in the typical commission that they would with a single bet.

The downside to the small group wager is that it requires a bit of trust between the participants, as well as a decent amount of social capital to set up a group of individuals who are all willing to place wagers together. Once those factors are in place, the benefits of the system are undeniable — a win–win for all involved. However, keep in mind that this is a fairly new development when it comes to sports betting and it is still somewhat unfamiliar territory for the vast majority of bettors. Therefore, it’s still a bit of a crapshoot whether or not this type of wager is going to be available when you make your next sports bet.

More Players Affected

One of the biggest draws of betting with fixed odds is that it’s almost always an easier wager to understand the outcome of. Not only does this make it simpler to predict, it also means that you will be affected by more players when you win or lose the bet. With fixed odds, there is less of a skill factor involved since everyone’s chances of winning or losing are exactly the same. This also makes it easier to place a wager since there are fewer variables to consider.

The downside to fixed odds is that if you’re playing against a skilled opponent, it can be very difficult to figure out exactly what is going on. This kind of adversarial style of play puts a bit of a strain on the betting relationship, as well as hampers the ability of the bookie to maintain a stable business. It might also mean that in the long run, you are paying more for the convenience of playing with fixed odds rather than earning more due to better odds in the first place.

Increased House Edge

Bettors who are looking to make larger wagers than usual should take note of the fact that there is more than one way for the house to get paid even when you win. The most common way is to take a piece of the action itself — either a percentage of the winnings or a portion of the action itself. Another way is to take a slice of the pot as a commission. The good news is that neither of these options are as bad as they seem — certainly not when you consider the alternative.

The downside to both of these options is that they require you to win, which is not always the case. What’s more, the house edge is something that is constantly in the back of your mind when you are playing — it’s a constant factor that could potentially sway the outcome of any game you play. The better you understand how the house edge works, the better prepared you’ll be to avoid giving the bookies too much leverage over you.

The last concept that we need to discuss when it comes to betting is collusion. Collusion occurs when two or more individuals either agree or consciously decide to work together in order to gain an unfair advantage over another player. This could take the form of collusion between the bookie and the player, or it could be between two individual players. Collusion is a serious offense in sports betting, and it’s something that almost everyone needs to be on the lookout for. It’s also important to note that collusion is not always malicious — sometimes just a lack of competition that makes everyone work together more easily. However, in any case, it’s an evil that needs to be eradicated in order to keep proper competition in the sports betting industry.
