Bet builders, also known as build-a-bet or sometimes bet creators, allow you to select different markets from a single match and combine them into one bet. It effectively operates as a single game accumulator, where you have multiple legs that all need to be correct selections for the bet to win.
The reason bet builders have become so popular among UK bettors is the mix of flexibility, fun and risk they provide. Once an innovation limited to a handful of bookmakers, they have since become a common feature. UK customers can now access bet builders across sites and sports.
What Is a Bet Builder?
A bet builder lets you combine multiple selections from the same event into one wager. You can choose as few or as many selections as you like, depending on your desired level of risk. Bookmakers typically provide a long list of bet-builder eligible markets, so it is easy to create a fully customised bet.
Most commonly, you will find bet builders available for football matches, and not just the high-profile fixtures. Many bookmakers also offer bet builders on other sports too, such as American football, tennis and basketball.
With a regular accumulator, punters need to pick selections from different matches to create a single stake bet. With a bet builder, you instead pick markets from within the same match. As with a regular accumulator, all selections you pick must be correct for the bet to be a winner.
Some bookmakers allow users to combine multiple bet-builder selections to create a bet builder accumulator.
How Bet Builder Odds Are Calculated
When creating a bet builder, the calculation of the odds is not as straightforward as it is for a regular accumulator. This is because often the markets are not totally independent of one another. Imagine you backed both teams to score and over 2.5 goals. Both teams scoring increases the likelihood of there being over 2.5 goals, so the two outcomes are linked.
Bookmakers can even reduce the combined odds when backing seemingly unrelated events, such as 10+ corners, 3+ cards and home win. Due to this additional margin that many bookmakers take, value can be harder to find in bet builders.
Popular Bet Builder Markets Explained
There is variation within the markets that a bookmaker will make eligible for bet builders. The selection also varies depending on the popularity of the event, with bigger matches having more markets. That said, there are some markets you can expect to find across events and sites for bet builders. The options below represent some of the commonly available ‘core’ bet builder options.
Match Result & Double Chance
As a starting point on a bet builder, many punters like to bet on the match outcome. This involves picking which team will win or picking a draw. This can provide a low-risk starting point when backing the match favourite. Alternatively, there is a double chance bet, in which you cover two match result outcomes, for example, away win and draw. By covering two outcomes, rather than one, your bet gains extra protection at the cost of lower odds.
Goals Markets
The two big goal markets are over/under goals and both teams to score. With over/under, you are backing whether the total goal count will be below or above the stated threshold. Over/under 2.5 goals is the standard option, but you can often find odds for 1.5 and 3.5 goals and so on.
With both teams to score, this market comes with a ‘Yes’ or ‘No’ option. Select ‘Yes’ if you think both teams will register at least one goal in the game. If you think one team, or both teams, will not score, select ‘No’.
Player-Based Selections
Rather than betting on team outcomes, many bookmakers support player-based markets. These usually include goals, assists, shots, cards, and tackles. Some sites also offer extra player options beyond these core markets.
Some bookmakers also run a “super sub” promotion. Under this offer, a player bet carries over to the substitute who replaces your selection. This prevents a substitution from immediately ruining your bet.
Despite this protection, player bets still need care. Avoid players who may start on the bench, as limited minutes will make it harder for players to achieve the necessary shot/goal/card/tackle total.
Cards and Corners
Betting on cards and corners works best with proper research. Data on average cards and corners is easy to find for teams and their opponents. Referee statistics also matter. Some officials issue cards more freely, while others take a lenient approach.
Match context is important for card bets. Local rivalries and high-stakes games often raise intensity and aggression. Many derby matches become heated, which can lead to more fouls and a higher card count than usual.
How to Build a Smarter Bet Builder
One of our main bet builder tips is to limit the number of selections you make. With each additional selection added, the bookmaker’s advantage grows. We recommend sticking to between two and four selections for bet builders.
Another big consideration is choosing markets that naturally align with one another. A player to score and have 3+ shots is an example of two markets that align well. Similarly, a team to win by 2+ goals and have the most corners makes sense, as a dominant attacking team will likely force more corners.
Focus on this, rather than adding unrelated add-ons in an attempt to boost your bet builder value. Unrelated markets make it easy to chase big odds, but what you need is value bets that have a good relationship between price and probability.
Finally, do your research, as even just a few minutes of checking relevant statistics can have a big impact on your long-term success rate.
When Bet Builders Make Sense
Bet builders suit matches with a clear narrative. This can be an expectation of an end-to-end match featuring teams of strong attacks and weak defences. Alternatively, it can be a feisty and cagey rivalry that is likely to be full of cards but lacking in goalmouth action.
Bet builders are also a great way of increasing the odds of an otherwise low-odds single bet. Backing a favourite to win at 1/2 may not offer appeal, but combining it with another selection can really boost the payout.
Lastly, bet builders work best for matches in which you know the teams/players well. It can help if you are watching the match live, as many bookmakers support in-play bet-builders.
When to Avoid Bet Builders
When using bet builders, avoid forcing high odds through numerous selections for entertainment purposes. Big potential payouts may offer appeal, but rarely do they offer good value. You should also not add unrelated selections just to increase the odds. Each leg should support the same match narrative.
Above all else, avoid chasing losses and resorting to betting on unknown leagues/sports. A lack of knowledge only multiplies risk and increases the bookmaker’s advantage.
Common Bet Builder Mistakes
Many bettors trust ‘obvious’ selections too much. Backing a selection at tiny odds adds unnecessary risk as it will barely impact the payout. Strong favourites can fail, while red cards and injuries can easily scupper player-specific elements of a bet-builder.
Another common mistake is overlooking how selections are linked. Many markets are not independent, and ignoring this can reduce value. Bookmakers also use special calculations to account for linked markets, which can make your bet lower value than expected.
The biggest error of all is chasing big returns. Bet builders with five or more selections and very high odds are rarely a wise strategy and often lead to long losing runs.
Final Tips for Using Bet Builders Effectively
Bet builders can be a useful tool, but punters should not overcomplicate them. It is best to keep bet-builders simple and logical. Select 2-4 events that all fit into the same narrative. Punters should always do their research for bet-builders too, and stick to fixtures they are familiar with, as data cannot tell you everything.
As with any betting, bet builders can produce losing runs. If this happens, ensure the focus stays on enjoyment, and you continue to gamble responsibly. Avoid chasing losses, as this can quickly turn fun into risk.
