What is a Bet Builder? A Beginner's Guide

A bet builder is a feature that allows you to combine multiple selections from a single sports event into a single, bet. This differs from an accumulator in which you bet on multiple results in different events. Bet Builders are more customizable and allow you to bet on various features within a game such as goalscorers, teams to score, players to get carded etc.

How a Bet Builder Works:

Before bet builders existed, you couldn’t place an accumulator using multiple selections from the same event or game because of related contingency.

For example, imagine you wanted to back two outcomes in a Liverpool match: Mohamed Salah to score and Liverpool to win.

Years ago, bookmakers wouldn’t allow you to combine those into a single bet. Why? Because if Salah scores, it increases the likelihood of a Liverpool win – meaning the two outcomes are related rather than independent.

With a standard double, the selections are unrelated, so the odds can simply be multiplied. But when bets are linked to the same event, a different calculation is needed to produce fair combined odds.

That’s where bet builders come in. They apply a pricing model that accounts for the relationship between the selections and calculates what the accumulator odds should be.

In this case, the bookmaker would factor in how much Salah scoring boosts Liverpool’s chances of winning and adjust the combined price accordingly.

Bet Builder vs. Accumulator (The Key Difference):

A bet builder and an accumulator both combine multiple selections into one bet for a bigger return — but they differ in how those selections work and what you’re allowed to combine. A bet builder and an accumulator both combine multiple selections into one bet for a bigger return — but they differ in how those selections work and what you’re allowed to combine. If you are looking for top-tier platforms that consistently offer these features, you can explore rankings of the best betting sites.

Example of a Bet Builder

A bet builder lets you combine multiple selections from the same match or event and is the perfect way of betting on one game (e.g., cards, goalscorers, corners, result).

A bet builder uses special pricing because the selections are often related and below we have an example to showcase this:

  • Example (Manchester City vs Tottenham Hotspur Bet Builder):
    • Erling Haaland to score
    • Over 2.5 goals
    • Cristian Romero to be carded

All of these selections will then be given an overall price which you can back.

Example of an Accumulator (Acca)

An accumulator combines selections that are usually from different matches or events and all selections must win for the payout.
Accumulators use simple multiplied odds because selections are unrelated and in different matches or events.

  • Example (Four-match accumulator):
    • Arsenal to win
    • Manchester City to win
    • Barcelona to win
    • Real Madrid to win

Key Features to Look for in a Bet Builder Site

Here we go through some of the key features that we look for in a strong bet builder site.

Odds & Payouts

Competitive odds ensure bettors get fair value when combining related selections within a bet builder, making the market attractive and worth using.

If you have clear and transparent payout limits, that then builds trust, so users know the maximum they can win before placing the bet. Together, they promote confidence in using the specific site for a bet builder.

Range of Available Markets

The best betting sites don’t restrict bet builders to just goalscorers – they offer a wide range of markets to combine. This includes options like shots on target, passes, tackles, cards, corners and more. A broader selection allows you to build more creative and tailored bets with bigger odds.

Mobile App Usability

A fast, intuitive app lets bettors create and adjust bet builders quickly, even while on the move. Smooth navigation and clear options reduce mistakes and frustration whilst speed ensures users can act on live events without missing opportunities.

Cash Out & Bet Editing

Allowing cash out gives bettors control to secure profits or minimise losses before the event ends. The ability to edit a bet after placing it adds flexibility if circumstances change or mistakes are spotted and both features make bet builders more user-friendly and dynamic so it’s something we look for.

Special Features (e.g., 'Super Sub')

Top bookies often stand out by offering unique features beyond basic odds.

One such standout feature is Super Sub (also known as “Sub On Play On” or “Impact Sub”) — it means that if your chosen player is substituted during a match, your bet automatically rolls over to the incoming replacement and stays live.

Bet Builder Strategy & Tips for 2025

There is no guarantee that you will win your bet builder, however we can give some tips and strategies to give you the best chance when building your bet.

Understanding Market Correlations

You can build smarter bet builders by choosing selections that logically support each other. For example, if a dominant team is likely to win, backing their star striker to score aligns with that outcome. Linking related events increases the chances of the whole bet landing, for example if Manchester City win, Erling Haaland is likely to have scored in the match.

Research is Key

Always check team news, recent form, and player stats before building a bet. This helps you avoid selections on injured, rested, or out-of-form players. Better information leads to smarter, higher-value bet builder choices.

The Role of In-Play Betting

Being able to build bets in-play lets you react to the flow of the match rather than guessing beforehand. You can spot momentum shifts, tactical changes, or standout performers and tailor your selections accordingly.

Conclusion: Build Your Perfect Bet

Bet builders have taken over the sports betting world, and they’re an excellent feature that allows for combinations of bets on the same event.

It’s important that users pick a site based on their personal needs from the information that we’ve provided throughout whilst also remembering to gamble responsibly whilst doing so.

Common Questions about Bet Builders in the UK (FAQs)

Yes, on most major sites, but it's not guaranteed. The option depends on the status of your live selections.

Primarily football, but also basketball, American football, and sometimes rugby or tennis on top sites.

Usually, yes, but always check the specific terms and conditions of the offer.

Bet builders work well both pre-match and in-play, but in different ways. Pre-match allows for research-based, well-planned selections, while in-play offers the advantage of reacting to how the game is unfolding. The “better” option depends on whether you prefer preparation or real-time strategy.
