A Goliath is the largest of the standard full cover bets. Pick eight outcomes and the bookmaker constructs 247 separate bets from them, every double, treble, four-fold and beyond. Nothing is left out. That density is its appeal and its cost: a £1 unit stake means £247 staked, and a single losing selection prunes the tree dramatically because the lines that needed it lose, even though dozens of others survive. This page walks through how a Goliath is built, how it settles, how the maths reads against a simpler accumulator, and where it sits among the full cover family.

Responsible Gambling

The Goliath is a high-volume bet. 247 lines, an outlay that rises with the unit stake, and a payoff dependent on a high proportion of picks landing. It is not the shape a bookmaker offers to make a punter’s life easy. Anyone considering a Goliath should set a deposit ceiling before opening the betting slip, decide the unit stake in advance, and treat the bet as an entertainment purchase rather than an investment.

GAMSTOP is the national multi-operator self-exclusion scheme. Every operator featured on this page is a GAMSTOP member, and registration with GAMSTOP blocks access to every licensed online bookmaker in Great Britain for the chosen period: six months, one year, five years, or five years with auto-renewal. After the minimum period, the exclusion continues for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps; betting shops use a separate service.

Since 7 May 2019, name, address and date of birth have been verified before a customer can deposit or gamble with a licensed operator. That check happens before the first bet, including with a free bet or bonus. Since 30 August 2024 a financial vulnerability check (LCCP condition 3.4.4) has applied to licensed remote betting when deposits minus withdrawals exceed £150 in a rolling 30 days. Since 28 February 2025 that check has been triggered at £150. It is a public-record check (bankruptcy, county court judgments), not an income or credit reference check. Operators must also offer a gross deposit limit on a fixed time frame.

The bookmaker’s margin sits inside every price a Goliath pays out on. The margin does not vanish because the bet is complex. The next sections explain where it lands.

Predictions, Strategy and Bankroll Thinking

A Goliath is not a search for a winner. It is a hedge. The structure lets a punter back eight opinions at once, knowing that some legs will lose, and the payoff from a well-chosen seven-out-of-eight still recovers the stake and pays a profit. The trade is volume for probability: a Goliath pays out across more combinations than a Yankee or a Heinz, so the payout surface is wider and the cliff edges are sharper when a key selection falls.

What the structure costs is the stake. At £1 a line, a Goliath costs £247. A punter building a Goliath is staking that the chosen eight outcomes are collectively strong, not that each one is a certainty. The realistic win scenario is six or seven legs landing with the eighth beaten by a late goal, an injury or a stewards’ enquiry. Those near-miss tickets do not pay on a standard accumulator. They do pay on a Goliath.

Bankroll thinking for full cover bets:

• Decide the unit stake before building the slip, not after.
• A Goliath that loses six legs returns nothing; a Goliath that wins six legs often returns less than the stake.
• Treat the full cover as a long-shot construction, not a core staking plan.
• Walk away when the calculation shows that each leg’s individual price already represents fair value. If the prices do, the multiplier built into the Goliath adds nothing.

No tipster or system knows an outcome in advance, and no sequence of bets converts a margin-loaded book into a margin-free one. What the punter controls is stake size, market choice, and the discipline to stop when the rules say stop.

Bet Types and Odds: How a Goliath Is Built

What the 247 Lines Are

A full cover bet is defined as all available multiple bets over a given number of selections. A Goliath covers eight selections and includes every double, treble, four-fold, five-fold, six-fold, seven-fold and eight-fold that can be constructed from them. The count is fixed: 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds, and one eight-fold accumulator. That sum, 28 + 56 + 70 + 56 + 28 + 8 + 1, is 247.

For settlement the bookmaker runs each line independently. The doubles are 28 in number because that is the number of distinct pairs available from eight items, calculated as eight choose 7 times two. The trebles, four-folds and beyond follow the same combinatorics. Each winning line pays at the multiplied odds of its legs, with the unit stake as the stake for that line.

How a Goliath Compares to Other Full Cover Bets

The full cover family has a recognisable shape, and each tier adds selections without changing the underlying logic: every multiple of every size, no singles.

A Lucky 15, Lucky 31 and Lucky 63 add singles to the full cover: 4 selections in 15 bets, 5 selections in 31 bets, and 6 selections in 63 bets respectively. A Goliath has no single-leg lines. Every winning bet is a multiple.

How a Goliath Settles

A Goliath settles line by line. Each combination of winning selections pays out at the multiplied odds of its legs. If seven of eight legs win, the eight seven-folds pay out. The 28 six-folds, 56 five-folds, 70 four-folds, 56 trebles and 28 doubles all settle as winning tickets. The single eight-fold accumulator pays if all eight win. If five of eight win, only the multiples that fit within those five settle. The six-folds, seven-folds and the eight-fold all need six or more winners.

The crucial consequence: a Goliath with one losing leg still produces dozens of winning tickets. The punter receives a return that reflects the multiplied odds of those surviving multiples, not a single accumulator payout.

Worked Example: Three Illustrative Prices

Take three illustrative selections at odds of 1/2 (1.50), evens (2.00) and 6/4 (2.50), with a stake of £10 for an accumulator or £2 per line for a full-cover bet. These are example prices for arithmetic, not quoted market prices.

A single accumulator across the three returns £10 × 1.50 × 2.00 × 2.50 = £75. Net profit is £65, and the payout share of the three-way market, summed from those illustrative prices, is 1 ÷ (1/1.50 + 1/2.00 + 1/2.50) = 1 ÷ (0.6667 + 0.5000 + 0.4000) = 1 ÷ 1.5667 = 63.83%. The margin on that illustrative market is therefore 36.17%, which sits well above a typical football 1X2 line because two of the three outcomes here are short prices where bookmakers load heavily. The arithmetic is illustrative; real markets carry their own margins.

A Goliath on eight such selections, all at comparable prices, sweeps hundreds of multiples, each paying a smaller amount than the single accumulator. The expected return on the unit stake is a function of how many legs win, multiplied by the combined odds of each surviving line. At £2 per line, the total stake is £494. Six winners across eight picks return a basket of doubles, trebles and four-folds, with no five-folds or beyond because those need five or six legs. That basket might recover something close to the £494 stake on strongly priced legs, or fall well short on a board of short-priced favourites.

The arithmetic shows why a Goliath is rarely the value structure. The accumulator concentrates the bet on the one outcome that needs every leg to land; the Goliath spreads the stake across hundreds of lines, most of which need more than the minimum number of winners. For an accumulator, one accumulator line must hit. For a Goliath, dozens of lines must hit for the bet to pay well, and most of the stake funds combinations that never settle as winners.

Odds Format and Margin in Practice

British bookmakers display odds in fractional form (5/1, 11/4, evens) by convention, with decimal form (6.00, 3.75, 2.00) shown alongside. The conversion is straightforward: fractional odds a/b map to decimal odds a ÷ b + 1. A Goliath paid in decimal form multiplies the leg decimals together for each line, then multiplies by the unit stake.

The bookmaker’s margin, sometimes called overround, is built into every price. On a three-way football market (home win, draw, away win), the payout share from the three implied probabilities is always below 100%, and the shortfall is the margin. The example above showed a margin of 36.17% on the illustrative three-way market, which is extreme. Real Premier League 1X2 margins typically run between 2% and 8% depending on the bookmaker and the timing of the price. A Goliath inherits the margin on every selection, so the overall margin compounds across the combinations.

Cash Out and Other Bet Features on a Goliath

Cash out is offered by some operators on full cover bets, settling the bet early at a price the operator states. Cash out availability is not guaranteed, and bets stand if cash out is unavailable. Midnite’s site lists an acca builder and price boosts with maximum-stake limits, which apply to singles and multiples alike. DAZN Bet lists Cash Out, Bet Builder, daily bet boosts and in-play betting. Cash out on a Goliath settles the entire bet at the operator’s stated price; it does not settle individual lines.

A bet builder constructs a single accumulator from markets within one event. A Goliath is different: it takes eight pre-existing selections and combines them into every multiple. The two features do not overlap.

Ten UK Bookmakers Offering Goliath Bets

The ten operators listed below all hold a Gambling Commission remote licence for general betting on real events, and each lists a full cover bet product in its sportsbook, although the tenured operators vary in which specific full cover sizes they support and how prominently they feature them. None of the offers below are recommendations to sign up; the table summarises the published headline terms and licence position so a punter can check each brand against the Commission’s public register before staking.

The Commission’s public register is the whole test of who holds a GB licence. The register can be searched by business name, trading name, domain or account number. A punter checking any of the brands above can confirm the licence by searching the register for the licence holder name or the account number. Licensed operators use both .com and .co.uk domains, so the domain alone proves nothing.

Fafabet

Fafabet runs on a Gambling Commission remote licence held by Taichi Tech Limited. Its headline racing feature is Best Odds Guaranteed on UK and Irish horse racing, win and each-way, from 9am on race days: if the starting price is bigger than the price the punter took, the bigger price is paid. That is a settled feature of the racing product rather than a Goliath-specific mechanic, but it sits alongside any Goliath punter’s racing slips. For Goliath users, Fafabet is a small-to-mid-sized bookmaker with a focused racing offer. The verdict: useful for racing-heavy Goliaths where BOG shifts a leg’s price, less relevant for football-only constructions.

Betway

Betway runs under Betway Limited on Gambling Commission account 39372. Its new-customer sports offer is £40 in free bet tokens (4 × £10) on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit card deposits only. The credit card ban at licensed operators means deposits funded via a credit card, including credit-card-funded e-wallet top-ups, are not permitted. Betway is one of the more established brands on the list and tends to support a broad range of multiples, including the Goliath. The verdict: a mainstream option for Goliath construction; the welcome offer’s minimum-odds and debit-card terms are ordinary for the UK market.

Bar One Racing

Bar One Racing, branded BAR 1 Betting, holds a Gambling Commission licence through Bar-One Racing Limited. It is an Irish independent bookmaker with shops across Ireland and horse racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. Its roots are in Irish racing, and its digital sportsbook carries the racing-heavy profile that follows. A Goliath at Bar One is most naturally built around its native racing markets. The verdict: a fit for Irish-racing Goliath construction where the racing markets are deepest, less of a fit for a punter whose eight selections are spread across football, tennis and basketball.

Unibet

Unibet has operated since 1999 and runs its UK site under Platinum Gaming Limited, Gibraltar, on Gambling Commission account 45322. The new-customer sports offer is “Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with free bets expiring within 7 days, for new GB customers using a debit card or instant bank transfer. Unibet is a long-tenured operator with a deep sportsbook and a recognised full cover product. The verdict: a Goliath is straightforward to build here, and the platform’s acca insurance on Premier League football is a relevant feature for any Goliath that includes Premier League legs.

DAZN Bet

DAZN Bet operates through DZBT Limited on Gambling Commission account 48756. Its site lists Cash Out, Bet Builder, daily bet boosts and in-play betting. Cash out availability is not guaranteed and bets stand if it is unavailable, which is the standard published position across the licensed market. DAZN Bet is a newer entrant to the market and its product breadth is still expanding. The verdict: useful for in-play and bet builder construction, and a Goliath can be built on the site, though the brand is less of a default choice than the longer-tenured operators for a Goliath-heavy staking plan.

Midnite

Midnite runs under Midnite Limited on Gambling Commission account 101839. Its site shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. The new-customer offer is £25 in free bets and 50 free spins for new customers who bet £5 or more on pre-match odds of EVS (2.0) or greater within 14 days of sign-up, with the free bets and spins valid for 7 days. Midnite positions itself around acca construction, and the price-boost feature is a relevant mechanic for any punter thinking about boosting one leg of a Goliath. The verdict: a good fit for a Goliath built around boosted legs, with the published stake limits on boosts being the headline constraint.

Sporting Index

Sporting Index operates through Sporting Index Limited on Gambling Commission account 27343. It is primarily a spread betting operator, but the new-customer offer runs through a fixed-odds path: a £10 fixed odds bet at minimum odds of 1/2 unlocks three £10 fixed odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets and a £1 Race Index spread bet. The qualifying fixed-odds bet cannot be placed in play or cashed out early. Sporting Index is the outlier on this list because its core product is spread betting rather than fixed odds. The verdict: a Goliath is buildable on the fixed-odds side, but the brand’s identity is in spread products, and a punter whose primary interest is Goliath construction may find the depth of fixed-odds markets narrower than at a mainstream sportsbook.

BetMGM

BetMGM UK is published by LeoVegas Gaming PLC on Gambling Commission account 39198. The new-customer offer is four £10 free bets, structured as two football accumulators of 4+ selections and two sports multiples of 2+, for new UK customers who deposit £10 or more and place a sports bet within 7 days, with minimum odds, 7-day validity and opt-in required. The structure of the free bets, which reward accumulator construction directly, is a relevant fit for any Goliath user. The verdict: a Goliath built around football selections maps directly to the football accumulator free bets, which is the clearest product-offer fit on the list for Goliath construction.

Fitzwilliam Sports

Fitzwilliam Sports operates through SBKI Limited on Gambling Commission account 48760. Its pricing model is notable: prices are based on Oddschecker’s average price for each selection. That is a different construction from a bookmaker setting its own line, and it means a Goliath built here reflects the broader market’s pricing rather than any single bookmaker’s view. The brand publishes Apple and Google mobile apps. The verdict: a sensible choice for a punter who wants the Goliath’s prices to reflect the market average rather than one operator’s margin; the trade-off is that the brand is smaller and the breadth of niche markets may be narrower.

Octobet

Octobet runs under Octopus Game Limited on Gambling Commission account 62545. Its headline feature is Best Odds Guaranteed on UK and Irish horse racing, up to £150 per customer per race. The cap is specific to that racing product. Like Fafabet, Octobet is a smaller, racing-focused brand on this list. The verdict: a fit for Goliath construction where racing legs are involved and BOG matters; less of a fit where the eight selections are spread across football and other sports.

Overview and Core Concepts

A Goliath is a full cover bet on 8 selections made up of 247 bets, covering all doubles, trebles and larger multiples. That single sentence is the definition. Everything else on this page expands it. The eight selections are picked first; the 247 lines are constructed automatically by the bookmaker from those eight; the punter chooses the unit stake, and the total outlay is that unit stake multiplied by 247.

The full cover family follows a recognisable pattern. A Canadian covers five selections in 26 bets. A Heinz covers six selections in 57 bets. A Super Heinz covers seven selections in 120 bets. The Goliath is the largest in the family. Beyond the Goliath, a Lucky 15, Lucky 31 and Lucky 63 add singles: 4 selections in 15 bets, 5 in 31 bets, 6 in 63 bets. A Goliath has no single-leg lines. Each leg must combine with at least one other to produce a winning line.

Three things make a Goliath distinctive:

1. Volume: 247 lines means 247 chances to win, but also 247 chances to pay for combinations that never settle as winners.
2. Survival payouts: even with one or two losing legs, the Goliath produces dozens of winning tickets because every multiple built from the surviving legs settles.
3. Stake structure: the total outlay is the unit stake multiplied by 247, so a £1 unit costs £247 and a £2 unit costs £494.

The Goliath pays best when six or seven of eight legs win. A perfect eight wins the single eight-fold accumulator plus every smaller combination, which compounds the price dramatically. A four-out-of-eight still produces some doubles and trebles, but rarely enough to recover the stake, and the return drops off sharply below five winners.

The book’s margin applies to every line. A Goliath pays out on lines whose multiplied odds reflect the margin on each leg and the compounded effect across combinations. The punter is not paying margin only on the eight-fold accumulator; the margin sits inside every line, and the overall expected return is reduced accordingly.

How a Goliath Differs From an Accumulator

An accumulator across eight selections is one line with eight legs, all of which must win for the bet to pay. A Goliath across eight selections is 247 lines built from those eight. The accumulator is a single ticket with a single payoff. The Goliath is a basket of tickets, most of which settle as losers but many of which survive when one or two legs drop.

The accumulator offers a clean trade: low probability of winning, but high return when it does. The Goliath offers the opposite trade: higher probability of producing a winning ticket, but a much wider spread of outcomes and a large portion of the stake funding combinations that never settle as winners.

For a punter who genuinely believes all eight picks will win, the accumulator is the cheaper way to express that view, because none of the stake funds combinations that are guaranteed losers. For a punter who expects six or seven wins out of eight, the Goliath’s survival payouts are the structure’s whole appeal. The difference is the bet’s underlying expectation, not the price.

When a Goliath Makes Sense

A Goliath fits when:

• The eight selections are independent events at prices that already look fair.
• The punter expects the eight to produce six or seven winners, not all eight.
• The unit stake can be set so that the total outlay (unit stake × 247) is an entertainment budget the punter can write off.

A Goliath does not fit when:

• The punter expects all eight to win: an accumulator is cheaper.
• The eight selections are heavily correlated (a same-game multi or bet builder would have built the same view in one line).
• The unit stake would push the total outlay past the punter’s entertainment budget.

Legality and Regulation in Great Britain

The Gambling Commission (UKGC) regulates the commercial gambling market in Great Britain under the Gambling Act 2005. The Act covers England, Scotland and Wales; Northern Ireland is outside it and runs on older law. The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport. Since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based, so a Curaçao, Maltese or Gibraltar licence is not a substitute for the GB licence. There is no state monopoly, no statutory cap on the number of licences, and no statutory list of permitted markets: an operator holds a licence for a category and offers markets under its own rules and the Licence Conditions and Codes of Practice (LCCP).

The relevant licence category for the operators on this page is remote general betting standard (real events). Other categories are remote general betting standard (virtual events), remote general betting limited, remote pool betting, and remote betting intermediary (the licence for betting exchanges). Spread betting that is a financial product is regulated by the Financial Conduct Authority, not the Commission.

Betting exchanges run under a betting intermediary licence, and rates and rules specific to exchanges are stated only from each exchange’s terms. Spread betting that is not a financial product is inside General Betting Duty. Off-course pool betting on horse or dog racing is a separate licence and duty.

Player Protection and Operator Duties

GAMSTOP is the national multi-operator online self-exclusion scheme, and it has been a mandatory licence condition for online operators since 31 March 2020. Every GB-licensed online operator is a GAMSTOP member. The minimum age is 18. Since 7 May 2019, name, address and date of birth are verified before a customer can deposit or gamble, including with a free bet or bonus. Since 30 August 2024 a financial vulnerability check has applied to licensed remote betting when deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025). That check is a public-record check (bankruptcy, county court judgments), not an income check or credit reference check.

Financial risk assessments (sometimes called affordability checks in the press) have been announced in a staged plan, with no start date confirmed. Deposit limits are required on a fixed time frame; the first changes applied from 31 October 2025, a second phase has been postponed to 30 September 2026, and whether the second phase is live is not established. There is no state-set deposit or loss ceiling for betting; limits are the customer’s choice, and the operator must offer the limit tool.

The bookmaker’s margin is set by the operator under its licence. The LCCP and Remote Technical Standards cover social responsibility, but the size of the margin is the operator’s commercial decision. No statutory cap on margin exists.

Bonuses, Free Bets and Promotions

The Commission does not license advertising. Advertising runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the LCCP marketing conditions. CAP Code section 16 requires marketing to be socially responsible, not of strong appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling or playing a significant role (with an exception for marketing placed where a bet can be made directly). That rule is about who appears in the advertisement, not who may bet.

Wagering requirements on bonuses are capped at 10x: a £10 bonus at 50x needed £500 of bets before the rule; under the cap no more than £100 of bets is needed. Mixed-product promotions, such as an offer that requires gambling on two or more product types, are banned under the rules in force since 19 January 2026. The cap applies to wagering requirements. Whether the cap applies to free bets with no wagering condition, and any cap on the money value of a bonus, are not established. The ten operators’ published welcome offers sit within this framework, but the £10 minimum-odds thresholds, debit card deposit restrictions, and 7-day expiries are each operator’s specific terms, and a punter claiming any of them reads the full terms first.

Tax

Players pay no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%, with a new remote betting rate of 25% applying from 1 April 2027 within it, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Spread betting has its own rates (3% financial, 10% other). Until 1 April 2027 the remote rate stays at 15%, and whether operators pass duty on through odds is not established. The Commission’s statutory levy is a separate charge from duty.

Offshore Operators

A GB licence is compulsory at the point of consumption. Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005 (on summary conviction up to 51 weeks’ imprisonment, a fine up to level 5, or both; six months in Scotland), aimed at the operator. No offence aimed at a customer who merely bets on an unlicensed site was found. The loss of protection is real: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and not bound by the 10x bonus cap or the £150 vulnerability check. Enforcement is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers; the Commission has been given, or is about to receive, court-order DNS blocking powers, though not yet in operation.

The honest framing: a GB licence means identity checks, deposit limits, GAMSTOP, and the bonus cap, but it also means verification before the first bet. An offshore brand runs on its own house rules, with no Commission recourse if funds are withheld. Neither is “the safe choice” by default; both have their own data-tax.

Checking a Licence on the Public Register

The Commission’s public register is the whole test of whether a brand holds a GB licence. The register can be searched by business name, trading name, domain or account number. The ten operators on this page all appear on the register with the account numbers listed earlier; the licence holders’ names and the registered domains are the verifiable entries. Punters checking any brand confirm the licence by searching the register for the licence holder name or the account number.

Frequently Asked Questions

What is a Goliath bet?

A Goliath is a full cover bet on 8 selections made up of 247 bets, covering all doubles, trebles and larger multiples. The bookmaker constructs 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds and 1 eight-fold accumulator from the eight picks. The punter chooses a unit stake, and the total outlay is that unit stake multiplied by 247. There are no single-leg lines. A Goliath settles line by line, so the structure pays out on combinations built from the winning legs even when one or two picks lose.

How many bets are in a Goliath?

1. The breakdown is 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds and 1 eight-fold accumulator, summing to 247. The number is fixed by the combinatorics of choosing multiples from eight items, and it does not change with the prices or selections involved. A unit stake of £1 makes the total outlay £247, while a £2 unit stake makes it £494. The full cover family uses the same combinatorics: a Canadian on 5 selections is 26 bets, a Heinz on 6 is 57, and a Super Heinz on 7 is 120.

How does a Goliath bet work?

The punter picks eight outcomes. The bookmaker constructs 247 separate bets from those eight, covering every possible multiple of every size. Each combination of winning selections pays out at the multiplied odds of its legs. The unit stake applies to each line. With seven of eight legs winning, the eight seven-folds pay, plus all the smaller combinations; with five of eight winning, only the doubles, trebles and four-folds built from those five settle, and the larger multiples need more winners. A Goliath pays best when six or seven legs win and pays poorly when fewer than five win. Cash out is offered by some operators on the entire bet, settling at the operator’s stated price.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is the whole test. The register can be searched by business name, trading name, domain or account number. The licence holders’ names for the ten operators on this page are Taichi Tech Limited (Fafabet), Betway Limited (Betway), Bar-One Racing Limited (Bar One Racing), Platinum Gaming Limited (Unibet), DZBT Limited (DAZN Bet), Midnite Limited (Midnite), Sporting Index Limited (Sporting Index), LeoVegas Gaming PLC (BetMGM), SBKI Limited (Fitzwilliam Sports) and Octopus Game Limited (Octobet). The Commission account numbers sit beside each entry. A search on any of those names returns the licence record. The register also lists the licence categories held: every operator on this page holds remote general betting standard (real events). Licensed operators use both .com and .co.uk domains, so the domain alone proves nothing.

How is the return on a bet worked out from the stake and the odds?

For a single bet, return = stake × odds. For a multiple, the odds of each leg multiply into one price, so an accumulator’s return is stake × (leg 1 odds × leg 2 odds × …). Net profit is return minus stake, which equals stake × (odds − 1). On a Goliath, each line is settled as a multiple, so the 247 returns are calculated line by line. A £10 stake at evens (2.00) returns £20, with £10 profit. A £10 accumulator across three legs at 1.50, 2.00 and 2.50 returns £10 × 7.50 = £75, with £65 profit. The bookmaker’s margin sits inside the odds and reduces the average return; the calculation above shows the gross return, not the net expected value.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the proportion of every unit staked that the bookmaker keeps on average. On a three-way market, the payout share is 1 ÷ (1/odds₁ + 1/odds₂ + 1/odds₃), and the margin is 1 minus that share. For example, illustrative prices 1.50, 2.00 and 2.50 give a payout share of 1 ÷ (0.6667 + 0.5000 + 0.4000) = 63.83%, and the margin is 36.17%. Real Premier League 1X2 margins typically run between 2% and 8% depending on the bookmaker and timing. A Goliath inherits the margin on every leg, so the overall expected return is reduced by the compounded margin across the 247 lines. The margin is visible by summing the implied probabilities: where the sum is below 100%, the bookmaker is operating at a margin below 100% (underround); where the sum is above 100%, the gap is the overround, the standard form of margin.
