Related selections are betting picks where one outcome affects the chance, price or settlement of another. In bet builders, they are important because you are combining connected markets from the same match rather than treating every leg like a completely separate acca selection.
What Are Related Selections in Betting?
A related selection is a pick that is linked to another pick in the same bet. This is also known as a related contingency. The key point is simple: if one selection wins, loses or changes probability, it can affect the likelihood of another selection in the same bet.
For example, “Arsenal to win 2-0” and “Arsenal to win the match” are related because a 2-0 Arsenal scoreline already includes Arsenal winning. In a normal accumulator, many bookmakers will reject that kind of combination or settle it differently if it is accepted in error.
Bet builders exist partly because bookmakers can now price some of these connected same-match outcomes through a dedicated bet builder engine. That does not mean every related selection will be allowed, and it does not mean the odds are simply multiplied like a standard acca.
Related Selections vs Unrelated Selections
| Example Combination | Relationship | Why It Matters |
|---|---|---|
| Team to win and same team to win 2-0 | Strongly related | The correct score already includes the match result, so this is usually blocked as a normal multiple and must be specially priced if allowed. |
| Player to score and player to have 2 or more shots on target | Related | A player who scores must usually have at least one shot on target, so the selections are not independent. |
| Both teams to score and over 2.5 goals | Related but not identical | A 1-1 scoreline lands BTTS but not over 2.5 goals, while 2-1 lands both. The outcomes overlap but one does not always guarantee the other. |
| Team to win and opponent goalkeeper to make 4 or more saves | Potentially related | If the winning team dominates attacking play, the opposing goalkeeper may face more shots, but it depends on match flow. |
| Player to be carded and total match cards over 3.5 | Related | One player card contributes directly to the total card count. |
| Horse in Race 1 to win and football team in a later match to win | Usually unrelated | One result normally does not affect the probability of the other, so this is closer to a standard accumulator relationship. |
Why Related Selections Matter in Bet Builders
Related selections matter because they change how the bookmaker prices the bet. In a standard accumulator, selections are usually expected to be independent enough for the odds to roll together. In a bet builder, the selections are often from the same fixture, so the bookmaker has to account for how each leg connects with the others.
This is why the final bet builder price may be lower than you expect when you add each leg manually. The bookmaker is not just multiplying the displayed prices; it is adjusting for correlation, overlap, market rules and its own margin. For a deeper explanation of this, see our bet builder odds explained guide.
Positive correlation
Positive correlation means two selections support the same match story. For example, a strong favourite to win, that team to score over 1.5 goals, and one of its attacking players to have shots on target can all point towards the same attacking performance.
Negative correlation
Negative correlation means the selections work against each other. For example, backing a team to dominate possession and win comfortably while also backing its goalkeeper to make a high number of saves may tell two different stories. It can still happen, but the logic is weaker.
Duplicate or nested outcomes
Some selections are not just related; they are almost duplicates. “Team to win 3-1” and “team to win” is the clearest example. The more specific selection already contains the broader one, so a bookmaker may block it, reprice it, or only allow it through a bet builder market.
Related Selections and Standard Accumulators
The difference between a bet builder and a standard accumulator is one of the most important parts of this topic. A normal acca usually combines selections from different events. A bet builder combines selections within the same fixture, where related outcomes are much more common.
| Bet Type | How Selections Usually Work | Related Selection Issue |
|---|---|---|
| Standard accumulator | Selections are usually from different matches, races or events. | Related contingencies are often rejected because one leg can affect another. |
| Bet builder | Selections are usually from the same fixture and priced together. | Related outcomes may be allowed, but the odds are adjusted by the bet builder engine. |
| Same game multi | Another name for a same-match multi-leg bet, used more often outside the UK. | The same correlation issues apply because the selections come from one event. |

How Bookmakers Price Related Selections
Bookmakers price related selections by estimating how much each leg affects the others. If two legs are strongly connected, the combined price will normally be shorter than a simple multiplication would suggest. If two selections only have a weak relationship, the adjustment may be smaller.
This is why a bet builder can feel different from a normal multiple. Adding a short-priced leg might not increase the overall odds much if that leg is already heavily implied by another selection. On the other hand, adding a market that introduces a genuinely separate condition can increase the odds more, but it also gives the bet another way to lose.
A useful habit is to convert the final price into implied probability before placing a bet. Our implied probability calculator can help you see what the odds are really asking to happen.
Football Bet Builder Examples With Related Selections
The examples below are not match tips. They are simple illustrations of how related selections can fit together inside a football bet builder.
Attacking favourite example
- Arsenal to win
- Arsenal over 1.5 team goals
- Arsenal player to have 2 or more shots on target
This is a positively related bet builder because all three selections are built around the same match view: Arsenal control the game and create enough attacking chances. The risk is that the player leg adds a more specific condition, especially if the player’s role, minutes or starting position changes.
Cards and rivalry example
- Over 3.5 total cards
- One central midfielder to be carded
- Both teams to commit a set number of fouls if available
This type of bet builder is built around a physical or stop-start match. The selections are related because individual cards and fouls can contribute to the wider disciplinary picture. It is important to check referee style, fixture intensity and player role rather than adding card legs only because the price looks appealing.
Goalkeeper saves example
- Favourite to win
- Favourite over 5.5 shots on target if available
- Underdog goalkeeper to make 3 or more saves
This example is connected through match pressure. If the favourite attacks often, the opposing goalkeeper may have more save opportunities. However, it can fail if the favourite scores from low shot volume, misses the target, or the underdog blocks shots before they reach the goalkeeper.

Related Selections on bet365 Bet Builder
bet365 is the bookmaker we currently cover in detail, and its Bet Builder feature is one of the most relevant places to understand related selections. On eligible fixtures, bet365 lets users combine available markets into one bet, with the combined odds updating as selections are added.
The important point is that bet365 Bet Builder pricing can account for whether markets affect each other. A selection that looks valuable on its own may add less to the final price if it is already strongly connected to another leg.

|---|---|---|
| Same-fixture selections | Confirm the selections are available within the Bet Builder tab for that match. | bet365 Bet Builder Guide |
| Selection limits | Check the current maximum selections and any player limits before building a large slip. | bet365 Bet Builder Max Selections |
| In-play markets | Prices and availability can change quickly once a match starts. | bet365 In-Play Bet Builder |
| Multiples | Check whether your Bet Builder can be combined with other eligible selections or other Bet Builders. | bet365 Bet Builder Multiples |
| Void selections | Player non-runners, postponed fixtures and void markets may affect the whole bet or recalculate it depending on the rules. | bet365 Bet Builder Void Rules |
| Cash out | Cash out is not guaranteed and can depend on market status, live price movement and bookmaker availability. | bet365 Bet Builder Cash Out |
How to Spot Related Selections Before You Place a Bet
A quick way to test a bet builder is to ask whether each leg adds a new condition or simply repeats the same idea in another form. If a leg only restates something that another leg already requires, the price may not improve much and the bet may become less efficient.
- Ask whether one selection automatically helps another selection win.
- Check whether one selection is already included inside a more specific selection.
- Look for conflicting match stories, such as a team dominating while also facing unusually high defensive pressure.
- Keep the number of legs controlled, especially when using player props, cards or corners.
- Check lineups, likely minutes, tactical role and set-piece duties before using player markets.
- Review market rules for 90 minutes, extra time, stoppage time, cards, corners, shots and void selections.
- Use a clear pre-bet checklist rather than adding legs only because the combined odds look bigger.

Good Related Selections vs Poor Related Selections
| Type | What It Looks Like | Why It Helps or Hurts |
|---|---|---|
| Clear positive relationship | Team to win, team over 1.5 goals, attacking player shots | The selections support one match view, but each leg still needs to be checked on price and probability. |
| Overlapping but not duplicate | BTTS and over 2.5 goals | The selections are connected but not identical, so the combination can make sense if the price is fair. |
| Duplicate or nested | Team to win 2-0 and team to win | The broader selection is already included in the specific scoreline, so it may be blocked or heavily adjusted. |
| Conflicting story | Team to dominate corners while the same team’s goalkeeper makes many saves | Both can happen, but they do not naturally support the same match script. |
| Too many fragile props | Several player shots, fouls, assists and cards in one slip | Each extra player condition adds role, minutes and match-state risk. |
Common Mistakes With Related Selections
- Treating a bet builder like a normal accumulator and expecting the displayed prices to multiply cleanly.
- Adding a broad selection that is already covered by a more specific selection.
- Using too many short-priced legs because each one feels likely on its own.
- Combining selections that tell different match stories.
- Ignoring team news, player position, substitution risk and tactical changes.
- Forgetting that all legs normally need to win for the bet builder to return.
- Not checking settlement rules before adding cards, corners, shots, player props or in-play markets.
- Placing a bet because a promotion exists rather than because the selections make sense together.
Our common bet builder mistakes guide covers these errors in more detail.
UK Betting Rules and Responsible Gambling Considerations
UK players should remember that bet builders are still gambling products. They can make a football match more detailed to follow, but they should not be treated as a way to guarantee returns or chase losses.
- You must be 18 or over to gamble in the UK.
- Only use licensed operators that are available legally in your location.
- Set a budget before betting and avoid increasing stakes after losses.
- Check whether a football market settles over 90 minutes plus stoppage time or includes extra time.
- Read the bookmaker’s rules for void players, abandoned matches, cards, corners and settlement sources.
- Use tools such as deposit limits, time-outs and self-exclusion if betting stops feeling controlled.

A Simple Method for Building Related Selections
A cleaner bet builder usually starts with one match view, not a target price. Decide what you think the game will look like, then add only the selections that genuinely support that view.
| Step | Question to Ask | Example |
|---|---|---|
| 1. Pick the match story | What is the main idea behind the bet? | The favourite controls possession and creates most chances. |
| 2. Choose the core market | Which selection best represents that story? | Favourite to win or favourite over 1.5 team goals. |
| 3. Add supporting legs carefully | Does each extra leg add a useful condition? | Team corners, player shots or opponent goalkeeper saves. |
| 4. Remove duplicates | Does any leg simply repeat another leg? | Do not add team to win if the chosen correct score already requires that team to win. |
| 5. Check the final price | Does the implied probability still look realistic? | Use odds and probability tools before placing the bet. |

FAQ
What are related selections?
Related selections are betting picks where one outcome affects the chance or meaning of another outcome. In football, examples include a team to win and the same team to win by a specific score, or a player to score and that player to have shots on target.
Are related selections allowed in bet builders?
Some related selections are allowed in bet builders because the bookmaker prices the combination as one same-match bet. However, not every combination will be accepted, and the final odds can be adjusted to reflect the relationship between the selections.
Why are related selections not always allowed in normal accumulators?
Normal accumulators usually rely on selections being separate enough to combine at rolled-up odds. If one selection directly affects another, the combined price can become misleading, so bookmakers often reject related contingencies or settle them under special rules.
Why are bet builder odds lower than multiplying each leg?
Bet builder odds can be lower than simple multiplication because the bookmaker accounts for correlation. If one leg makes another leg more likely, the combined price is adjusted instead of being treated like two unrelated events.
Is positive correlation good in a bet builder?
Positive correlation can make a bet builder more logical because the selections support the same match view. It does not guarantee value or success, because the bookmaker may already reflect that relationship in the final price.
What is a related contingency?
A related contingency is another term for a related betting outcome. It describes selections where the result of one leg affects the probability, settlement or price of another leg.
Can a related selection be void?
Yes. A related selection can be void depending on the bookmaker’s rules and the reason for the void. Player non-participation, postponed fixtures, abandoned matches and market-specific rules can all affect how a bet builder is settled.
Is a bet builder the same as an accumulator?
A bet builder is similar to an accumulator because multiple selections are combined and all legs usually need to win. The main difference is that a bet builder normally combines markets from the same fixture, while a standard accumulator usually combines selections from different events.
How many related selections should I add?
There is no perfect number. A smaller bet builder with two or three well-explained selections is often easier to assess than a large slip with many fragile player props. Every added leg should have a clear reason for being included.
Are related selections available in-play?
Some bookmakers offer in-play bet builders on selected events, but available markets and prices can change quickly. Always check the live bet slip, market status and current rules before placing an in-play bet builder.
