Bet Builder is one of the most popular betting features that you can find at almost any sports betting website.

Given how popular it is among the bookies and the bettors, we decided to explain in more detail what Bet Builder is and provide you with some of our top Bet Builder betting predictions. We'll also show you what you could get if you used the Bet365 link at the top to place an acca on both builders coming through.

Before we go on and talk about this feature in more detail, we first want to provide you with our top Bet Builder picks. If you are a new player, you can use your Bet365 bonus code to increase your potential winnings by reducing your risk.

Espanyol vs Real Madrid: Three-Legged Bet Builder @ 10/1 (11.00)

Kick-Off: 16:00, 30/08/26

Both teams to score: Yes
Half-time result: Draw
Anytime goalscorer: Kylian Mbappe

We kick off our BetBuilder predictions with a La Liga clash between Real Madrid and Malaga, and we are confident that both teams will find the net in this clash. As it stands, Los Blancos have failed to keep a clean sheet in this competition so far, and both teams were on the scoresheet in six of Real Madrid's last eight outings, seven of Malaga's last eight fixtures, and in four of the last five H2Hs.

Although Real Madrid have won nine of their last 10 matches across all competitions, it is worth mentioning that their two La Liga fixtures this season have both been tied at the half-time break. Interestingly, this has also been the case in Malaga's last three fixtures. Moreover, Kylian Mbappe scored a hat-trick against Real Sociedad earlier this week and is on course for his third consecutive La Liga Golden Boot title. The French forward, who scored 10 goals and registered four assists in eight FIFA World Cup appearances this summer, will fancy his chances against a struggling Malaga side.

Lecce vs Roma: Three-Legged Bet Builder @ 53/10 (6.30)

Kick-Off: 17:30, 31/08/26

Match result: Roma to win
Total goals: Under 2.5
Anytime goalscorer: Donyell Malen

AS Roma cruised to a comfortable 4-0 victory over Fiorentina in their Serie A opener, and although Lecce also kicked off their new campaign with a win, they have had a poor track record against Roma in recent years. The visitors were victorious in the last four clashes between these outfits and are unbeaten in the last 11 H2Hs (W9, D2).

This will likely be a low-scoring affair. Roma have kept clean sheets in the last three meetings between these outfits, so it is unsurprising that four of the last five H2Hs have gone below the 2.5-goal threshold. Similarly, fewer than three goals were scored in six of Lecce's last eight outings. We also fancy Donyell Malen to find the net. The Dutch forward was only three goals shy of Serie A's Golden Boot last term. He has picked up where he left off this season, scoring a hat-trick in Roma's league opener.

What Is the Bet Builder Feature?

Bet Builder is a feature that allows bettors to place multiple bets on the same game. In a nutshell, it is a feature that helps you create an accumulator bet where all selections are from one match or event. However, keep in mind that you can also create a Bet Builder bet with as few as two selections.

Another thing that's important to know is that the Bet Builder odds you get will likely be lower than the odds you would get if you just multiplied your selections, as you would do with a regular accumulator bet. However, that is the price you have to pay if you want to bet on multiple betting markets from a single game – you wouldn't be able to do this otherwise, without using the Bet Builder feature.

The most popular use of Bet Builder is for football games, but you can use this feature to bet on other sports as well, like basketball, ice hockey, tennis, cricket, and many others. That being said, some bookies limit Bet Builder offers to football or just the most popular events from other sports.

On top of that, it's important to keep in mind that not all bookies have this feature or if they do, it might be called something other than Bet Builder, like Same Game Multi or Request a Bet.

In fact, Bet Builder has previously known as the Request a Bet feature, where you would have to send your selections to your bookie via social media (usually on Twitter with a specific hashtag) or email and then wait for them to respond with the odds. With the Bet Builder feature, that process is automated and you get your odds instantly, although some bookies still use the Request a Bet feature instead.

How to Use the Bet Builder Feature

Using the Bet Builder Feature is rather simple. The first step is to find a bookmaker that offers the Bet Builder feature. Once you do this, just follow these steps:

Choose the match you want to bet on
Click on the Bet Builder tab for the game you selected
Start building the bet by adding your selections (click on the desired betting market to add the selection)
With each selection you add, you will instantly see the odds for your Bet Builder wager
Once you add all selections that you want, place/confirm your bet

Keep in mind that Bet Builder only works with pre-game betting markets, so you won't be able to place a Bet Builder wager on live games. Also, the Bet Builder feature will automatically eliminate conflicting or contradictory combinations, so you won't be able to make a mistake like that when you place your bet.

Bet Builder on Mobile Apps

Given the rise of popularity when it comes to mobile sports betting, most bookies today also have mobile apps that you can download, install, and use to place your bets. Also, most of the bookmakers that offer the Bet Builder feature provide it on both their desktop site and mobile app, although in some cases, the Bet Builder feature can be found exclusively on one of the platforms. As we explained in our presentation of the bet365 app, betbuilder is available on all devices.

Bet Builder Odds

As we already mentioned, Bet Builder odds aren't the same as odds on regular accumulator bets since they aren't calculated the same way by simply multiplying the odds. In fact, each bookmaker has its own way to calculate the odds for their Bet Builder feature, so Bet Builder odds for same selections can vary from one bookie to another.

We tested this to check out which bookies offer the best Bet Builder odds and found that Betfair had the best odds, followed by Unibet, 888sport and bet365, while the other bookies were behind. However, this was tested on a few examples only and the result could be different from one game to another. Our article on the best bet of the day goes into more in detail on which bookie is offering what on that particular day.
