How to Use Bet Builder on bet365 - Complete Guide with Tips
Short Summary
bet365 Bet Builder+ lets you combine markets from multiple different events into one single bet — so instead of a standard acca where you're just picking match winners, you can mix and match goalscorers, corners, cards and results across several games at once.
What is bet365 Bet Builder+?
Bet Builder+ is an upgraded version of the standard Bet Builder feature. The key difference is that standard Bet Builder lets you combine markets within a single event — for example, backing a player to score anytime AND the match to have over 2.5 goals in the same game. That's still available.
Bet Builder+ goes a step further by letting you combine markets across multiple selected events into one single bet. Think of it like building a custom accumulator where each leg isn't just "team to win" — it can be any market you want from each game.
The odds update in real time as you add each selection, giving you one combined price for the whole bet.
Bet Builder vs Standard Accumulator — What's the Difference?
| Feature | Standard Acca | Bet Builder | Bet Builder+ |
|---|---|---|---|
| Markets per selection | 1 (e.g. match result) | Multiple (same event) | Multiple (different events) |
| Events covered | Multiple | Single event only | Multiple events |
| Market types | Standard markets | Combined within one game | Any popular market, any game |
| Odds calculation | Multiplied | Recalculated in real time | Recalculated in real time |
| Price potential | High | Medium-High | Very High |
The short version: Bet Builder+ gives you the flexibility of a Bet Builder with the multi-game scope of an accumulator. You get to craft the exact bet you want rather than being limited to standard match winner markets.
How Are Bet Builder Odds Calculated?
This is something most guides skip over — but it's essential to understand before you start building bets.
When you add selections to a Bet Builder, the odds are not simply multiplied together like in a standard accumulator. bet365 runs a real-time recalculation that factors in how closely related your selections are to each other.
Why Can't They Just Multiply the Odds?
In a normal accumulator across different games, each leg is independent. Manchester United winning has no effect on Real Madrid winning — so the bookmaker can multiply the odds and apply their standard margin.
Bet Builder works differently because all your selections come from the same event (or related events in Bet Builder+). Markets within the same game are correlated — they influence each other's probability. For example:
- If you back a team to win AND over 2.5 goals, these are positively correlated — a dominant win usually means a high-scoring game.
- If you back a team to win AND under 2.5 goals, these are negatively correlated — harder to combine, and the bookmaker prices it differently.
- If a player scores anytime AND the team wins, these overlap significantly — a goal from your player directly contributes to the win.
If the bookmaker just multiplied correlated odds, they'd be offering artificially inflated prices on bets that are much more likely to win together. So they adjust the combined price downward to reflect the true joint probability.
A Concrete Example
| Selection | Individual Odds |
|---|---|
| Arsenal to win | 2.00 |
| Over 2.5 goals | 2.00 |
| Saka to score anytime | 4.00 |
Simple multiplication: 2.00 × 2.00 × 4.00 = 16.00
Bet Builder actual price: approximately 10.00–12.00
The gap — roughly 4 to 6 points here — is the correlation adjustment. All three selections are positively correlated: if Arsenal dominate and Saka scores, over 2.5 goals is very likely too. The bookmaker reduces the price to account for this overlap.
Does This Mean Bet Builder Is Bad Value?
Not necessarily — it depends on what you're combining. Here's the key insight:
- Positively correlated markets (team wins + high scorer + over goals) — the price reduction is smaller because the bookmaker sees them as connected. You still get a fair combined price.
- Negatively correlated markets (team wins + under 2.5 goals + no red cards) — the price reduction can be heavier, because these outcomes pulling against each other makes the bet harder to land.
- Unrelated markets combined randomly — you get a steeper margin applied overall, as the bookmaker applies more caution to unusual combinations.
The sweet spot is building bets where your selections tell a consistent story. If you think Arsenal will dominate a match, everything that follows from dominance (win, goals, their key player scoring) will be priced more favourably together than a random mix of unrelated outcomes.
Bottom line: Bet Builder odds will always be lower than straight multiplication. That's by design, and it's not necessarily unfair — it reflects the real probability of correlated events happening together. The skill is in building combinations where the story is coherent, so the correlation works in your favour rather than against you.
How to Use Bet Builder on bet365 — Step by Step
- Log in to your bet365 account — Go to the sport you want to bet on and find your chosen fixture or event.
- Select the Bet Builder tab — On the event page, look for the "Bet Builder" tab in the header navigation. Click it to open the available markets.
- Add your selections — Pick from the most popular markets displayed. Each selection you add will automatically recalculate the combined odds.
- Review your price — Once you're happy with your selections and the overall price, click "Add to Bet Slip".
- Enter your stake and confirm — Place your bet as normal from the bet slip.
For Bet Builder+, the process is the same but you'll be adding selections from multiple different events rather than just one. The combined price for all your selections across all events appears on the bet slip.

Advantages of Bet Builder+
- Much bigger prices than standard accas Combining specific markets (goalscorers, cards, corners) across multiple games generates significantly higher odds than just backing match results.
- Full customisation You build exactly the bet you want — not just what the standard markets offer. If you think a player will score and get booked in the same match, you can back both in one bet.
- Odds update instantly Every selection recalculates the price in real time, so you always see exactly what you're getting before you commit.
- 20+ sports available Far more variety than most bookmakers' bet builder products.
- Can be combined in multiples Bet Builder bets can be included in multiples with other Bet Builder bets or combined with non-Bet Builder selections.
Disadvantages of Bet Builder+
- Harder to win than a regular acca More selections and more specific markets means more ways to lose. The big price comes with big risk.
- Void rules are complex If a market within your Bet Builder is voided, the outcome depends on the sport, bet type and whether it's pre-match or in-play. (See section below.)
- Not available for all bet types Bet Builder bets cannot be used in Banker, If Bet, Reverse If Bet or Teaser bets.
- Cash Out not always available While Cash Out may be available on some Bet Builder bets, it's not guaranteed across all markets.
- F1 and Golf restrictions Formula 1 is pre-race only, Golf is pre-game only — no in-play Bet Builder for these sports.
What Happens if a Selection is Void?
This is one of the most common questions about Bet Builder — and the rules differ depending on the sport.
For most sports (in-play): If any selection is made void, the entire Bet Builder is voided. You get your stake back.
For pre-match Bet Builders in specific sports (Football, American Football, Ice Hockey, Basketball, Baseball, Cricket, Rugby League, Australian Rules, Rugby Union, Golf): If a player market within the bet is voided, the Bet Builder is recalculated for the remaining selections — you don't lose the whole bet.
Horse Racing: If a horse in your Bet Builder becomes a non-runner, selections on that horse are voided and the Bet Builder is recalculated for the remaining selections. Prices may also be recalculated in line with standard Horse Racing rules if there's a non-runner in the field.
Tennis: If your Tennis Bet Builder includes a selection on a set that never takes place (because the match was won before that point), the Bet Builder is settled as a loss — not a void.
Australian Rules dead heat: If a selection results in a dead heat, your return is divided by the number of tied participants.
Bet Builder Tips
From experience, here are a few approaches that tend to work well when building bets on bet365:
- Stick to correlated markets. If you're backing a team to win, also back them on the Asian handicap or total goals — these markets naturally relate to each other and the odds won't be as dramatically reduced compared to adding random selections.
- Don't go above 5-6 selections. Each additional selection increases the chance of one leg failing. A 4-5 selection Bet Builder at 15/1 to 25/1 is often a sweeter spot than a 9-leg monster at 200/1.
- Research player markets carefully. Anytime scorer and card markets are popular but volatile. Check team news, injury status and recent form before adding player-specific selections.
- Use Bet Builder for bigger games. The more markets available, the more flexibility you have to build a genuinely informed bet. Top-flight football and tennis majors give you the most options.
- Consider smaller stakes. Because these bets are harder to win, treating them as high-reward punts with smaller stakes is sensible risk management.
Example of Bet Builder in Action
Let's say there's a Premier League match: Arsenal vs Chelsea.
Instead of just backing Arsenal to win at 8/11, you build a Bet Builder:
- Arsenal to win
- Over 2.5 goals in the match
- Bukayo Saka to score anytime
- Over 9 corners in the match
Each individual selection might be evens or under. Combined into a Bet Builder, the odds could land anywhere from 10/1 to 20/1+ — all in one bet, one stake, one result. That's the appeal.
FAQs
What is Bet Builder+ on bet365?
Bet Builder+ is the upgraded version of Bet Builder that lets you combine popular markets from multiple different events into one bet — not just within a single match. It gives you bigger price potential by building a cross-game accumulator with fully customised markets.
How does bet builder work on bet365?
Navigate to your chosen fixture, click the Bet Builder tab, then select as many markets as you want from those available. The combined odds recalculate with every selection. Once done, add to your bet slip, enter your stake and confirm.
What happens if you lose one bet in a bet builder?
If any single selection in your Bet Builder loses, the whole bet loses — just like a regular accumulator. All selections must win for the bet to pay out. The only exception is if a market is voided (see void rules above).
How many bet builders can you do on bet365?
There's no stated limit on how many Bet Builder bets you can place. Within a single Bet Builder, you can include up to 12 markets from a single sport. You can also combine multiple Bet Builder bets into a multiple.
Are bet builders a good way to bet?
They can be, when used smartly. The key advantage is getting bigger odds on specific outcomes you've researched. The risk is that more selections = more chances to lose. Stick to 4-6 well-researched selections rather than building 10-leg shots in the dark.
What's the difference between a Bet Builder and an accumulator?
A standard accumulator lets you combine multiple match results (or similar markets) across different events. A Bet Builder lets you combine any market — goalscorer, corners, cards, result — within a single event or across events (Bet Builder+). Bet Builders give you much more flexibility in what you back.
Why is my bet365 Bet Builder not working?
Common reasons include: the markets you're trying to combine are incompatible (some markets can't be combined within the same event), the feature isn't available for that specific event, or there's a temporary technical issue. bet365 notes it cannot guarantee availability at all times for technical reasons.
Final Verdict
Bet Builder+ is one of the best features bet365 offers, especially if you like football betting and want more than just backing a winner. The ability to customise your selections across multiple markets — and have them all priced up in real time — gives you genuine control over your bets rather than relying on whatever the standard markets offer. Just keep your selections focused, do your research on player markets, and treat these as high-reward bets with appropriate stakes.
