A Goliath is the largest commonly named full-cover multiple bet, covering eight selections in 247 individual bets. Every possible combination from doubles to the eight-fold accumulator is included, except singles. At least two winners are required for any return.

What Is a Goliath Bet? (Definition & Overview)

The Core Definition of a Goliath

A Goliath bet is a full-cover multiple bet that automatically generates every possible combination of bets from a pool of eight selections. Unlike a standard accumulator, which requires all selections to win, a Goliath provides comprehensive coverage: if any two or more of your eight selections win, you will have winning bets within the structure.

The defining characteristic of a Goliath is its 247 individual bets, which breaks down as follows:

The structure is mathematically precise. With 8 selections, there are exactly 28 possible pairs (doubles), 56 possible triplets (trebles), and so on, up to the single combination of all 8 (the eight-fold accumulator). Crucially, no singles are included — a single winning selection returns nothing, no matter how high its odds.

Why Is It Called a "Goliath"?

The name "Goliath" derives from the biblical giant in the story of David and Goliath. Just as Goliath was famously enormous and imposing, the Goliath bet is named for its sheer scale — 247 bets, a massive structure, and a potentially enormous cost. The naming convention reflects the bet's dominance in the hierarchy of full-cover multiples.

The biblical reference also carries a subtle irony: while Goliath was a giant, he was ultimately defeated by a smaller, more nimble opponent (David). Similarly, while a Goliath bet appears formidable, it requires discipline and strong selection quality to be profitable. Many casual bettors place Goliaths hoping for a "giant" return, only to find that the high cost and complexity work against them.

How Does a Goliath Bet Work? (Mechanism & Structure)

Understanding the 247 Individual Bets

The Goliath's power lies in its comprehensive coverage. Instead of choosing one specific combination (e.g., "all 8 must win"), the Goliath automatically places bets on every meaningful combination of your 8 selections.

Imagine your eight selections are horses in different races:

• Doubles cover every pair: Horse A + Horse B, Horse A + Horse C, Horse B + Horse C, and so on.
• Trebles cover every triplet: Horse A + B + C, Horse A + B + D, and so on.
• Four-folds cover every group of four, and so on.

This systematic coverage means that if, say, four of your eight selections win, you will have winning bets across multiple combinations: 6 different doubles (from the 4 winners), 4 different trebles, and 1 four-fold. Each of these bets multiplies the odds of its constituent selections, creating a cascade of potential returns.

The mathematics behind 247 is the sum of all combinations (excluding singles):

C(8,2) + C(8,3) + C(8,4) + C(8,5) + C(8,6) + C(8,7) + C(8,8) = 28 + 56 + 70 + 56 + 28 + 8 + 1 = 247

The Eight-Fold Accumulator Explained

The eight-fold accumulator is the crown jewel of the Goliath. It is the single bet in which all eight selections must win. The odds for this bet are calculated by multiplying the odds of all eight selections together.

For example:

• If each of your 8 selections has odds of 2.0 (evens), the eight-fold pays 2.0⁸ = 256 times your unit stake.
• If the average odds are 3.0, the eight-fold pays 3.0⁸ = 6,561 times your unit stake.

At a 10p unit stake, hitting the eight-fold at 3.0 average odds would return £656.10 from just that one bet — a life-changing sum from a modest stake. This explosive upside potential is what attracts bettors to Goliaths, even though the probability of all eight selections winning is extremely low.

Minimum Winners Required for a Return

A critical question for any Goliath bettor: How many of my eight selections need to win for me to get any money back?

The answer is a minimum of 2 winners.

With 2 winners, you activate the doubles. A double is the lowest-value combination in the Goliath, and even at modest odds (e.g., 2.0 × 2.0 = 4.0), a double return on a 10p stake would be 40p — a small profit on your £24.70 total stake, but a profit nonetheless.

With only 1 winner, no bets in the Goliath return anything. The single winning selection has no partner, so no double, treble, or higher combination can be formed. This is a critical risk factor: a bettor could select seven winners and one loser, and still receive no return.

How Much Does a Goliath Bet Cost? (Cost Breakdown & Examples)

Calculating Total Stake

The total cost of a Goliath is straightforward: Unit Stake × 247.

Most recreational bettors place Goliaths at 5p or 10p per line to keep the total cost between £12–£25. Even professional bettors rarely exceed 25p per line unless they have exceptional conviction in their selections.

The cost reflects the sheer volume of bets being placed. A £1 Goliath is equivalent to placing 247 separate bets, each with its own stake. This is why bankroll management is critical: placing a Goliath at too high a unit stake can quickly deplete a betting account.

Each-Way Goliath (Doubles the Cost)

An each-way Goliath adds another layer of complexity and cost. In each-way betting, you place two separate bets for each outcome:

1. A win bet (selection must finish first)
2. A place bet (selection must finish in the top 2, 3, or 4, depending on the event)

An each-way Goliath therefore creates 494 total bets (247 win bets + 247 place bets), doubling the cost. A £1 each-way Goliath costs £494, and a 10p each-way Goliath costs £49.40.

The advantage of each-way Goliaths is that they provide more paths to a return. Even if a selection doesn't win, it may place, triggering place bet combinations. However, the doubled cost makes them even more expensive and suitable only for bettors with high conviction and adequate bankroll.

Bankroll Management Tips

Rule 1: Never stake more than you can afford to lose. A Goliath should represent a small percentage of your total betting budget — ideally no more than 2–5% of your monthly betting funds.

Rule 2: Match your unit stake to your selections' quality. If you have eight selections you are genuinely confident about, a 10p–25p unit stake is reasonable. If you are scraping together eight selections just to place a Goliath, reduce the stake to 5p or skip the bet entirely.

Rule 3: Consider your minimum return expectations. With a 10p Goliath costing £24.70, even two winners at 3.0 odds each would only return about £1.80 profit. Is that return worth the risk? Many bettors find it isn't, which is why they reserve Goliaths for occasions when they have multiple high-confidence selections.

Goliath Bet Examples: From 2 to 8 Winners (Practical Scenarios)

Scenario 1 – Exactly 2 Winners (Only Doubles Return)

Setup: 10p Goliath (£24.70 total cost). Selections A and B win at 3.0 and 4.0 respectively; the other six lose.

Calculation: Only one double is activated: A × B = 3.0 × 4.0 = 12.0.
Return: 0.10 × 12.0 = £1.20
Profit: £1.20 − £24.70 = −£23.50 (loss)

With only 2 winners, even at decent odds, the return barely scratches the surface of the stake. This illustrates why Goliaths are risky bets for bettors without multiple strong selections.

Scenario 2 – 3 Winners (Doubles + Trebles Return)

Setup: 10p Goliath. Selections A, B, and C win at 3.0, 4.0, and 2.5 respectively.

Winning bets activated:

• Doubles: A×B (12.0), A×C (7.5), B×C (10.0) = 3 doubles
• Trebles: A×B×C (30.0) = 1 treble

Calculation:

• Doubles: 0.10 × (12.0 + 7.5 + 10.0) = 0.10 × 29.5 = £2.95
• Trebles: 0.10 × 30.0 = £3.00
• Total return: £5.95
• Profit: £5.95 − £24.70 = −£18.75 (loss)

Even with 3 winners, the return remains negative. The Goliath structure only becomes profitable when you have 4 or more winners at reasonable odds.

Scenario 3 – 4+ Winners (Exponential Growth)

Setup: 10p Goliath. Selections A, B, C, and D win at 3.0, 4.0, 2.5, and 5.0 respectively.

Winning bets activated:

• Doubles: C(4,2) = 6 doubles
• Trebles: C(4,3) = 4 trebles
• Four-folds: C(4,4) = 1 four-fold

Calculation:

• Four-fold: 0.10 × (3.0 × 4.0 × 2.5 × 5.0) = 0.10 × 150 = £15.00
• Trebles and doubles add another £10–£20 depending on odds
• Total return: approximately £35–£45
• Profit: approximately £10–£20

With 4 winners, the Goliath finally becomes profitable. The four-fold accumulator is the turning point.

Scenario 4 – All 8 Winners (The Jackpot)

Setup: 10p Goliath. All eight selections win at an average of 3.0 odds.

The eight-fold accumulator:

• Return: 0.10 × (3.0⁸) = 0.10 × 6,561 = £656.10

Additional returns from all doubles, trebles, four-folds, five-folds, six-folds, and seven-folds:

• Estimated additional return: £300–£500 (depending on exact odds)

Total return: approximately £956–£1,156
Profit: approximately £931–£1,131

Hitting all 8 selections is rare, but when it happens, the returns can be extraordinary. A 10p stake becomes over £900 in profit.

Goliath vs Other Full-Cover Bets: How Do They Compare?

Goliath vs Heinz (6 Selections, 57 Bets)

A Heinz bet covers six selections in 57 bets (15 doubles, 20 trebles, 15 four-folds, 6 five-folds, 1 six-fold).

Key differences:

• Goliath has 2 more selections (8 vs 6), creating 247 bets instead of 57
• Goliath costs approximately 4.3× more at the same unit stake
• Goliath offers more comprehensive coverage but requires greater bankroll and selection quality
• Heinz is more suitable for bettors with 6 strong selections; Goliath requires 8

When to choose: Use a Heinz if you have exactly 6 selections you're confident about. Use a Goliath if you have 7–8 selections and want maximum coverage.

Goliath vs Super Heinz (7 Selections, 120 Bets)

A Super Heinz covers seven selections in 120 bets, sitting between the Heinz and the Goliath.

The Super Heinz is a middle ground. If you have seven selections, a Super Heinz is more efficient than a Goliath because it requires one fewer selection while still offering substantial coverage. However, if you have eight selections, the Goliath's additional coverage (127 extra bets) may be worth the extra cost.

Goliath vs Round Robin (Different Structure)

A Round Robin is fundamentally different from a Goliath. While a Goliath is a full-cover bet that automatically includes all combinations, a Round Robin is a user-selected combination bet where you choose specific combinations to include.

Key difference: A Goliath automatically generates all combinations; a Round Robin gives you control over which combinations to include. A Round Robin can be cheaper because you exclude unwanted combinations, but it requires more manual selection and offers less automatic coverage.

When Should You Place a Goliath Bet? (Strategy & Use Cases)

Ideal Conditions for a Goliath

A Goliath is only worth considering when all of the following are true:

1. You have 8 genuinely strong selections. Not "decent" or "interesting" — selections you have genuine conviction about based on form, odds, and analysis.
2. The odds are attractive. If your selections are all heavily favored (odds of 1.5 or lower), the potential returns from a Goliath are modest even if all win.
3. You can afford the cost without impacting your bankroll. A Goliath should never force you to reduce stakes on other bets or compromise your betting budget.
4. You understand the risk. With only a 2-winner minimum, a Goliath can return a small profit even with a poor hit rate, but it can also drain your bankroll quickly if selection quality is poor.

Common Use Cases in Horse Racing

Horse racing is the traditional home of Goliaths. A typical scenario:

Multi-race day (e.g., Royal Ascot, Cheltenham Festival): A racing analyst identifies eight races with strong selections. Rather than placing singles or doubles on each race, they place a 10p Goliath covering all eight selections. If four or five selections win, the Goliath returns a meaningful profit. If all eight win, the return is substantial.

Advantages in horse racing:

• Large cards with many races provide ample selection opportunities
• Odds tend to be higher (2.5–5.0 range) than football, creating better eight-fold potential
• Racing bettors are accustomed to managing multiple selections across events

Goliath in Football and Other Sports

Football is increasingly popular for Goliaths, especially during weekends with multiple matches or tournaments.

Example scenario: Champions League night with 8 matches. A bettor selects a strong team to win in each match (e.g., Manchester City, Liverpool, Real Madrid, PSG, Bayern Munich, Juventus, Inter Milan, Ajax). A 10p Goliath covers all 247 combinations. If 4–5 teams win, the Goliath is profitable.

Advantages in football:

• Multiple matches available on most weekends
• Odds are typically in the 1.8–3.0 range, suitable for Goliaths
• Clear win/loss outcomes (no place bets to complicate things)

When NOT to Place a Goliath

Avoid Goliaths when:

• You have fewer than 8 selections you're confident about (use a Heinz or Super Heinz instead)
• Your selections are all heavy favorites (odds below 1.5) — the potential return won't justify the cost
• You're placing a Goliath "just to have a bet" without genuine conviction in the selections
• Your bankroll can't sustain the cost without impacting other bets
• You're chasing losses and hoping a Goliath will recover your deficit

What Are the Key Advantages and Disadvantages?

Advantages of Goliath Bets

1. Comprehensive Coverage
A Goliath automatically covers every combination of your selections. You don't have to manually select which doubles, trebles, and accumulators to include — they're all there. This eliminates the risk of missing a winning combination because you didn't think to include it.

2. Potential for Massive Returns
The eight-fold accumulator can generate extraordinary returns. At average odds of 3.0, an eight-fold pays 6,561 times the unit stake. A 10p stake becomes £656.10 from a single bet. Combined with returns from lower-level accumulators, the total return can be life-changing.

3. Flexibility in Odds
Unlike a standard accumulator where all selections must win at their exact odds, a Goliath's structure means you profit from partial wins. With 4–5 winners, you're already in profit, even if some selections lost.

4. Psychological Appeal
There's something compelling about the Goliath's structure. The idea of placing 247 bets with a single stake has a certain elegance, and the potential for a huge return from a small stake is inherently attractive.

Disadvantages and Risks

1. High Cost
£247 for a £1 stake is substantial. Even at 10p per line (£24.70), the cost adds up quickly. Many bettors can't afford regular Goliaths and must reserve them for special occasions.

2. Requires 8 Strong Selections
Finding 8 selections you're genuinely confident about is hard. Most bettors have 3–4 strong opinions on any given day. Forcing yourself to find 8 selections just to place a Goliath often leads to weak selections and losses.

3. Complexity
Understanding how a Goliath works — the 247 combinations, the minimum 2-winner requirement, the impact of odds on returns — requires study. Many casual bettors place Goliaths without fully understanding the mechanics, leading to poor decisions.

4. Low Returns from 2–3 Winners
With only 2–3 winners, your return is often minimal or negative. You need at least 4 winners at decent odds to make a meaningful profit. This creates a "feast or famine" dynamic: either you hit 4+ winners and profit well, or you hit 2–3 and lose money.

5. No Singles
If you have one selection you're extremely confident about and seven weaker selections, a Goliath forces you to include all eight. You can't exclude the weak selections. This "all or nothing" structure can be frustrating.

Common Misconceptions About Goliaths

Misconception 1: "You need all 8 selections to win."
Truth: No. A Goliath returns money with just 2 winners (via the doubles). This is one of the Goliath's greatest strengths.

Misconception 2: "A single winner is worthless."
Truth: Correct. A single winner activates no bets in the Goliath (since there are no singles). This is a critical risk.

Misconception 3: "Goliaths are only for expert bettors."
Truth: Partially true. Understanding a Goliath doesn't require expertise, but using one profitably does. Casual bettors can place Goliaths, but they should do so rarely and only with genuine conviction in their selections.

Misconception 4: "A Goliath is always better than eight separate singles."
Truth: Not necessarily. Eight separate singles allow you to profit from each winner individually. A Goliath requires multiple winners to profit. The choice depends on your selection quality and risk tolerance.

How Do You Calculate Goliath Returns? (Calculation Methods)

Manual Calculation (Doubles Example)

For a simple double (two selections), the calculation is straightforward:

Return = Stake × Odds1 × Odds2

Example: 10p double at 3.0 and 4.0 odds.
Return = 0.10 × 3.0 × 4.0 = £1.20

For a treble (three selections):
Return = Stake × Odds1 × Odds2 × Odds3

Example: 10p treble at 3.0, 4.0, and 2.5 odds.
Return = 0.10 × 3.0 × 4.0 × 2.5 = £3.00

With a Goliath, you're calculating returns for all 247 combinations. Doing this manually is impractical, which is why calculators are essential.

Using a Goliath Bet Calculator

A Goliath bet calculator automates the process. You input:

1. Your unit stake (e.g., 10p)
2. The odds for each of your 8 selections
3. Whether it's a win bet or each-way bet

The calculator then computes:

• Total cost
• Return if all 8 selections win
• Return if 7, 6, 5, 4, 3, or 2 selections win
• Profit/loss at each level

Popular Goliath calculators:

• AceOdds Goliath Calculator
• Outplayed Goliath Calculator
• BetHQ Goliath Calculator
• William Hill Goliath Calculator

These are free and accessible on mobile and desktop. Using a calculator before placing a Goliath is essential to understand your potential returns.

Impact of Rule 4 Deductions

In horse racing, Rule 4 is a bookmaker rule that reduces odds if a horse is withdrawn or becomes a non-runner. The reduction is proportional to the withdrawn horse's odds.

Example: You place a 10p Goliath with one selection at 5.0 odds. That selection is withdrawn. The bookmaker applies a Rule 4 deduction to all bets involving that selection. If the deduction is 25%, the 5.0 odds become 3.75 odds for all bets involving that selection.

Rule 4 deductions reduce your potential returns but are unavoidable in horse racing. Most Goliath calculators have a Rule 4 feature that allows you to input deduction percentages and recalculate returns.

Frequently Asked Questions About Goliath Bets

Q: How many bets are in a Goliath?
A: 247 bets across eight selections, covering every combination from doubles up to the eight-fold accumulator. No singles are included. At £1 per line, a Goliath costs £247.

Q: How many winners are needed for a Goliath to return anything?
A: At least 2 winners, to activate one of the 28 doubles. Without singles, a single winner returns nothing.

Q: At what unit stake is a Goliath usually placed?
A: Most recreational bettors place Goliaths at very small unit stakes — 10p (£24.70 total) or 5p (£12.35 total) — to keep the total cost manageable while still covering all combinations.

Q: Is the Goliath the largest named bet type?
A: Yes, the Goliath is the largest commonly named full-cover bet. Larger full-cover bets on nine or more selections exist mathematically but are not standard named products at most bookmakers.

Q: Can you place a Goliath on the same event?
A: No. Multiple bet rules prevent all eight selections from coming from the same event. Selections must be spread across different events, typically on the same day or weekend.

Q: What is a Super Goliath?
A: A Super Goliath extends the Goliath to 9 selections, creating 2,187 bets. It is not a standard named product at most bookmakers and is rarely offered due to its extreme cost (£2,187 at £1 per line).

Q: Is a Goliath bet worth it?
A: A Goliath is worth it only if you have eight genuinely strong selections with high confidence in each one. The high cost and requirement for at least 2 winners make it unsuitable for casual bettors with weak selections. If you're unsure, use a Heinz or Super Heinz instead.

Conclusion

A Goliath bet is a powerful tool for experienced bettors who have identified eight strong selections and want comprehensive coverage of all possible combinations. The potential for a massive return — especially from the eight-fold accumulator — is genuinely exciting. However, the high cost, complexity, and requirement for multiple winners mean that Goliaths should be used sparingly and only with genuine conviction.

For most casual bettors, a Heinz or Super Heinz offers a more manageable entry point into full-cover betting. But for those with the bankroll, the selections, and the understanding of how Goliaths work, the potential rewards are substantial. Use a Goliath calculator before placing any bet, manage your bankroll carefully, and remember: a Goliath is a marathon bet, not a sprint. Patience and selection quality are key.
