What is a Bet Builder?
A bet builder combines selections from the same match or event into one bet.
With a standard builder, every leg must win for the bet to pay out.
For example:
Home team to win + over 2.5 goals + over 8.5 corners.
That football bet builder needs a home win, at least three goals and at least nine corners.
The bookmaker calculates a price, multiplying the odds while also accounting for how selections affect each other.
Best Bet Builder Sites Reviewed
Here’s what the best sites offer beyond a basic same-game combination:
bet365
Cricket, rugby and Formula 1 builders: Tennis, both rugby codes and cricket feature alongside football and the main American sports. Formula 1 builders are pre-race only.
Build in-play or across events: Combine up to 12 selections before or during an event. You can also mix different builders from different sports into one big bet.
Boosts on selected builders: 'Winnings Boost' offers increase your potential return on featured events. The offer shows the boost and which combinations qualify.
Void player picks don't cancel the bet: Eligible pre-match builders continue after a void selection is removed, with the remaining selections repriced.
Paddy Power
Stats beside your selections: 'Bet Build Assist' shows player and team records from the previous five matches, helping you assess a pick without leaving the builder screen.
Season-long combinations: Builders around title winners, top-four finishes and relegation across competitions including the Premier League, EFL, La Liga and Serie A.
Boost and refund tokens: Tokens can increase the odds on your own builder or provide a free bet refund when one selection loses.
Sky Bet
One wrong pick can be removed: 'Ghost Leg' pays the remaining winners at revised odds. Apply a token to a pre-match builder with 5+ selections at combined odds of 3/1 or higher.
Boost your own combination: 'Booster' tokens add extra profit to eligible bet builders. Your reward shows the percentage increase and maximum stake.
Extra-time can count for your player picks: Some goal-scorer, shots and tackles markets include the extra 30 minutes in your builder. Look for 'including extra time' beside markets.
Kwiff
Not every pick has to win: 'Flex' lets you allow losing selections in exchange for lower odds. Your builder can still pay winnings - not just refund your stake.
Your odds can get a boost: Kwiff can randomly increase your builder’s odds after you place it, without increasing your stake.
Combine builders across matches: 'Bet Builder+' lets you put builders from different games into one accumulator, rather than betting on each separately.
Ladbrokes
Horse racing bet builders: Combine a horse to win, another to place and a winning distance prediction. The racing bet builder covers UK and Irish racing.
Free builder bets from score predictions: Two correct scores in the free weekly '1-2-FREE' game earn a £2 builder free bet. You have seven days to use it once it's issued.
Mix football and racing bets: You can combine racing builders with other sports selections, rather than keeping your football and racing bets separate.
Betfred
Cash bonuses on winning builders: 'Builder Bonus' starts at 15% extra profit, when you choose 3+ selections at combined odds of 3/1 or higher. The maximum stake is £10.
£20 in builder welcome free bets: These form part of the £50 welcome package when you sign up, after a qualifying £10 bet at evens or higher.
Build around passes, tackles and fouls: Selected fixtures offer detailed player markets, giving you more ways to include midfielders and defenders - not just goal-scorers.
BetMGM
25% boosts for football and NFL: Selected customers receive extra bet builder profits on featured games. Qualifying builders need at least four selections.
Player bets follow the substitute: 'Golden Sub' transfers eligible football player selections to their replacements. It works on both pre-match and in-play builders.

How We Pick the Best Bet Builder Sites
Our hands-on reviews of betting sites are the starting point.
We only recommend UK Gambling Commission-licensed bookmakers, then look closely at what their builders offer.
Sports and Markets
We check which sports support builders and which selections you can combine. Broad coverage matters.
Odds Value
We compare the price of builders with identical selections and settlement rules. An advertised boost means little if another bookmaker offers a better price on the same bet.
Builder Offers
We assess cash bonuses, refund tokens and other builder promotions, including who qualifies and how rewards work
Our free bets and betting offers guide covers promotions more widely.
Settlement and Payouts
We check what happens when a player doesn’t start, is substituted or has a selection voided. We also compare cash-out options and features that allow a losing pick, explaining how these affect your payout.
Mobile Experience
We test how easily we can find markets, edit a builder and follow its selections on a phone. Clear bet tracking matters when several player bets are running at once.
Our best betting apps guide compares the wider mobile experience.
Bet Builder FAQs
Do all bet builder sites offer the same markets?
No. Sports coverage and available selections vary between bookmakers. Taking football as an example, some builders allow bets on main markets like results, corners and goals, while others include player passes, tackles, fouls and shots. The best choice depends on the combinations you want to place.
Can I use a free bet on a bet builder?
Often, but it depends on the reward. Some free bets are specifically for builders, while others exclude them or require a minimum number of selections. Check the token’s permitted bet types and expiry date before choosing how to use it.
Can I combine bet builders from different matches or events?
Some sites let you combine several builders into one accumulator, sometimes alongside ordinary selections. Each builder becomes part of the larger bet, so one losing selection can affect the entire accumulator - not just the builder containing it.
What happens if a player in my football bet builder doesn’t start?
It depends on the bookmaker and player market. If the selection is voided, it may be removed and the odds recalculated, or the whole builder may be cancelled and your stake refunded. Substitution offers don’t automatically cover players who miss the starting line-up.
Can I cash out a bet builder?
Many bet builder sites offer cash out on eligible builders, but it isn’t guaranteed throughout a match. It can disappear while markets are suspended or prices change, and the amount offered may be below your stake. Don’t place a builder assuming you can always cash out later.
