A Super Heinz is a full-cover combination bet on seven selections: 120 bets total, including doubles, trebles, and higher multiples, with no standalone singles. It sits between a Heinz (six selections, 57 bets) and a Goliath (eight selections, 247 bets), paying out on any combination where at least two runners win. This page details how the bet is built, settled and priced, lists ten Gambling Commission-licensed bookmakers that support it, and gives a worked payout example using three illustrative odds.

Top 10 UK Bookmakers for a Super Heinz Bet

Ladbrokes — the high-street benchmark for Acca Insurance and BOG

Ladbrokes runs on a Gambling Commission remote licence held by LC International Limited (Commission account 54743, site Ladbrokes.com) and combines odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish racing, in-play markets and Acca Boosts. A Super Heinz built on its slip inherits the same settlement rules as any acca: a void leg drops to the next-lowest multiple, so a six-fold settles as a five-fold and a treble settles as a double, with one-stake-the-line across all 120 bets. It is a solid choice for any bettor who already uses BOG pricing or the in-play product, and the Acca Insurance feature can save a stake on the rare occasion a single leg lets an entire 120-bet sequence down.

BetMGM — the welcome offer in four free bets, each with its own minimum

BetMGM UK is published by LeoVegas Gaming PLC, lists Gambling Commission account 39198, and its sports welcome for new customers who deposit £10 or more and place a sports bet within 7 days is four £10 free bets — two on football accumulators of four selections or more and two on sports multiples of two selections or more — each valid for 7 days with minimum odds and an opt-in required. A £40 free-bet bundle split by product type is unusual: it is four stake-not-returned tokens, not a single credit, and the acca leg count differs from one token to the next. Worth it for a new customer willing to read four sets of terms; the structure is heavier than a flat £40 free bet on paper but tidy if four of the welcome legs line up with bets the punter was placing anyway.

NetBet — Daily Boosts and a Bet Builder that recalculates instantly

NetBet’s UK licence is held by Netbet Enterprises Limited (Commission account 39170), its product stack includes Daily Boosts, Profit Boosts and free bet offers alongside a Bet Builder with instant dynamic odds, and its app carries sports stats for major leagues. The instant-odds recalculation on the Bet Builder is what matters for a Super Heinz: any same-game leg the punter adds feeds straight into the multiples on the slip, with the 120 prices rebuilt without a delay-heavy refresh. It is a highly efficient platform for bettors who build same-game combinations and want the price to update live on the slip.

Fitzwilliam Sports — Oddschecker-averaged prices and a thin app footprint

Fitzwilliam Sports runs on a remote licence held by SBKI Limited (Commission account 48760), bases its prices on Oddschecker’s average price for each selection and ships an Apple and a Google mobile app. Pricing on the average rather than a single-source line tends to compress the headline price against competitors but tightens the spread across the seven legs of a Super Heinz, which can matter when the punter is paying a margin 120 times over. The platform is best suited for a bettor who prefers line-tracking over an aggressive headline price and is comfortable using a specialist app for the comparison backbone.

Fitzdares — racing, antepost and Lucky 15s the slip treats as a default

Fitzdares holds a Gambling Commission licence through Fitzdares Limited (Commission account 400) and the app covers horse racing, football, tennis, rugby, cricket, golf and American football, with cash out, accumulators, Lucky 15s, specials and antepost markets alongside in-play live odds. A Super Heinz built on antepost runners is a different risk shape from one built on the day — non-runner voids are routine in the antepost book, and a voided leg demotes a seven-fold to a six-fold without refunding the rest of the stake. Worth it for a racing-led punter who thinks in terms of Lucky 15s and four-fold combinations and is happy to carry the non-runner rule into seven-figure bets.

Kwiff — the Supercharge random price boost on any single or multi

Kwiff’s UK licence sits with Eaton Gate Gaming Limited (Commission account 44448), and its Supercharge feature can boost a bet’s odds instantly — for example from 2/1 to 20/1 — on singles or multis across any sport. A Supercharge landing on one leg of a 120-bet Super Heinz does not transform the bet’s expected value: it raises one price across all combinations containing that leg, which is a one-leg change dressed up as a multi-leg headline. This is an interesting option for a bettor who prefers unpredictable price boosts to standard promotions, though the volatility of Supercharge can sometimes lag behind real-time market movements.

Octobet — Best Odds Guaranteed up to £150 a customer, a race at a time

Octobet’s remote licence is held by Octopus Game Limited (Commission account 62545), and it offers Best Odds Guaranteed on UK and Irish horse racing up to £150 per customer per race. The BOG cap is a per-race limit rather than a daily one, so a customer betting on five consecutive races from the same meeting uses £150 of headroom per race, not a flat £150 across the day. Worth it for a racing punter who bets singles and small multiples into BOG and treats the Super Heinz as a singles-hedge rather than a primary bet type.

Matchbook — an exchange where the punter pays the other side of the bet

Matchbook operates on a remote licence held by Triplebet Limited (Commission account 39504) under both a remote general betting standard (real events) licence and a remote betting intermediary licence — the second of those is the licence category that funds betting exchanges. On an exchange, the punter backs or lays selections, the prices are set by the customers rather than the bookmaker, and a Super Heinz built on back prices pays out the same way as a bookmaker Super Heinz but without the overround the bookmaker embeds. It serves bettors who understand back-and-lay dynamics, though on small football markets, the thin liquidity may require more careful navigation for a full 120-bet Super Heinz.

Betfred — Bet Builder, Sub Switch and a racing-led data product

Betfred’s remote licence is held by Petfre (Gibraltar) Limited (Commission account 39544), and the app pairs Bet Builder and Sub Switch with Racing Post data and Extra Places, alongside live casino and bingo on the same account. Sub Switch is the rare feature that lets a punter swap a starting player out for a substitute before kick-off in named markets, which can save a Super Heinz leg that has been broken by a late team sheet. Worth it for a football punter betting into Bet Builder who treats player news as a price input rather than a closing factor.

QuinnBet — free bets valid 7 days, restricted on multiples

QuinnBet’s UK remote licence is held by QuinnBet (Gibraltar) Limited (Commission account 61011), and its free bets are valid for 7 days from credit, can be used on any market at odds of 1/2 (1.5) or greater, allow straight accumulators but exclude Trixies, Patents and Yankees, with maximum odds of 50/1. QuinnBet does not list the Super Heinz in its excluded-bet list, but a 120-bet full-cover combination is treated by most operators as a multiple rather than an accumulator, and the rule that bans Trixies, Patents and Yankees casts doubt on whether the Super Heinz qualifies. Worth it for a customer placing singles and short accumulators into a 7-day free-bet window; a Super Heinz with seven legs above evens is on shakier ground under the same terms.

What a Super Heinz Bet Actually Is

A Super Heinz is a full-cover combination bet on seven selections, and the word “full-cover” means every multiple from two selections up to seven is included. There are no singles. The 120 bets split as 21 doubles, 35 trebles, 35 four-folds, 21 five-folds, 7 six-folds and 1 seven-fold, which is the count that has held on bookmaker betting-type reference pages since the bet was first sold on the high street. The bet was named after the “57 varieties” marketing line of a Heinz food brand — itself a US reference that crossed into British betting nomenclature decades ago.

It belongs to a small family of full-cover bets named by the number of selections they cover. A Trixie covers three (4 bets), a Yankee four (11), a Canadian or Super Yankee five (26), a Heinz six (57), the Super Heinz seven (120) and the Goliath eight (247). A Super Heinz sits one rung above the Heinz and one below the Goliath. The arithmetic is the binomial coefficient C(n, k) for each leg count: with seven selections, the number of ways to pick 2 is 21, to pick 3 is 35, to pick 4 is 35, to pick 5 is 21, to pick 6 is 7 and to pick 7 is 1, summing to 120.

The unit stake is set by the punter — say £2 a line — and is multiplied by all 120 combinations, so a £2-per-line Super Heinz costs £240. Lowering the per-line stake to 50p brings the bill to £60; raising it to £10 brings it to £1,200. The punter does not pick which selections go into which combinations; the bookmaker does, by treating every possible multiple of two or more as a separate bet inside the slip.

How a Super Heinz settles

A Super Heinz pays out on any combination that contains only winners. With all seven selections winning, every one of the 120 bets settles — the doubles, the trebles, the four-folds and the seven-fold — and the total return stacks a seven-fold payout on top of a six-fold, a five-fold, and so on down to the doubles. With six winners and one loser, the seven-fold drops out, the six six-folds reduce to those not containing the loser, the five-folds stay whole where they don’t depend on the loser, and the trebles and doubles pay out where they fit. With five winners and two losers, the seven-fold, all six-folds and all five-folds are gone, but every treble and double drawn from the five survivors pays. With four or fewer winners, every line needs at least two selections to win before any payout occurs, and the return falls sharply as selections drop.

Void selections follow the same demotion rule as any multiple bet. A void leg in a treble makes the treble settle as a double on the remaining winners. A void leg in a Super Heinz folds the voided runner out of every combination it touched, and the lines that still have at least two live winners settle as their reduced multiples. Stakes on affected combinations are not refunded; the rest of the bet carries on.

Worked payout at three illustrative prices

The calculation below uses a unit stake of £2 per line and three illustrative prices — 1/2 (1.50), evens (2.00) and 6/4 (2.50) — applied across seven selections in this order: one selection at 1.50, two at 2.00 and four at 2.50. The figures are an example, not a quoted price, because no real Super Heinz payout can be calculated without seven real prices on seven real runners. The maths shows how the 120 lines combine.

Assuming all seven selections win, the seven-fold alone returns £2 × 1.50 × 2.00 × 2.00 × 2.50 × 2.50 × 2.50 × 2.50, which works out to £300. Every other multiple pays on top, and the total return across the 120 lines sits in the £540-to-£580 band, depending on the rounding of each line. The stake is £240, so a winning Super Heinz at those prices puts the net profit in the £300-to-£340 band. Two or three winners reduce the payout to the surviving doubles and trebles — a few pounds at those prices — and one winner pays nothing, because every line in a Super Heinz needs at least two winners to settle.

The number of separate combinations rises sharply as more selections win. One winner pays nothing. Two winners turn on exactly one double at the price of the two. Three winners turn on three doubles and one treble. Four winners turn on six doubles, four trebles and one four-fold. Five winners turn on ten doubles, ten trebles, five four-folds and one five-fold. Six winners turn on fifteen doubles, twenty trebles, fifteen four-folds, six five-folds and one six-fold, on top of all the smaller multiples. Seven winners turn on every line. The shape of the return rises with the number of winners, with most of the cash concentrated in the larger multiples.

How a Super Heinz differs from an accumulator

A Super Heinz is not an accumulator. An accumulator — an “acca” in British betting — is a single bet on all selections to win in one combination: a seven-fold accumulator pays only if all seven selections win, and the stake is one line. A Super Heinz pays out on every two-selection combination at minimum, which means it is not “all-or-nothing” and gives the punter a return when some — but not all — selections hold up. The drawback of an accumulator is that one loser takes the whole stake. The drawback of a Super Heinz is that the stake is 120 times larger for the same per-line return.

A Lucky 63 covers six selections across 63 bets (six singles included). A Super Heinz covers seven selections across 120 bets (no singles), so the Super Heinz is the same family shifted up one rung: a Lucky 63 is to six selections what a Super Heinz is to seven, minus the singles. A patent on three selections covers 7 bets including singles; a Trixie covers 4 bets excluding singles. The naming is consistent across the family, and the family is dense — there is no “Super Lucky 63” between them.

The Legal Landscape for a UK-licensed Super Heinz

In Great Britain there is no statutory list of permitted markets. A bookmaker holds a licence for a category and offers markets under its own rules and the Gambling Commission’s Licence Conditions and Codes of Practice, with the Gambling Act 2005 as the framework. The 2014 amending Act made a Commission licence compulsory for any operator whose remote facilities are used in Great Britain, regardless of where that operator is based — a Curaçao, Maltese or Gibraltar licence is not a substitute. The Commission’s public register can be searched by business name, trading name, domain or account number and is the whole test of whether a brand holds a licence.

Every operator listed on this page holds a remote general betting standard (real events) licence, and most run under a single licensee rather than a cluster — a brand is not the same as a licensee. Ladbrokes and Coral run under LC International Limited; Paddy Power and Betfair run under Flutter; the Ladbrokes account number is 54743 and the bet slip on Ladbrokes.com is the same product family as the Coral slip. Listing them as independent operators would overstate the competition on the Commission register. The licensee name is the legal party; the domain is the trading face.

Betting exchanges hold a separate licence category — remote betting intermediary — and Matchbook is the only exchange on the shortlist, running on a remote licence held by Triplebet Limited under both a general betting and an intermediary licence. Betting exchange rules (commission on net winnings, the back-and-lay mechanics, peer-to-peer liquidity) are stated only from each exchange’s own terms, and a Super Heinz on an exchange pays out on the same mathematical combinations as a bookmaker Super Heinz.

Financial spread betting is regulated by the Financial Conduct Authority, not the Gambling Commission — Spreadex is a useful example of a firm that holds both an FCA authorisation for spread betting and a Commission licence for fixed-odds betting, and the two products are governed by different rules. Spread betting losses can exceed the deposit, which is the structural warning that separates spread betting from fixed-odds staking.

The minimum age is 18, and since 7 May 2019 every licensed remote operator verifies a customer’s name, address and date of birth before the first deposit — including when a free bet or bonus is involved. Identity checks cover any gameplay, even before a stake is risked, and the deposit is the trigger, not the bet. Verification is mandatory at every licensed brand on the shortlist.

Safer Gambling Around a Super Heinz

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for every online operator licensed in Great Britain since 31 March 2020. Self-exclusion periods run six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. Every brand on the shortlist, including Matchbook, Betfred and QuinnBet, takes part in GAMSTOP, and operators have been required to enrol since 31 March 2020.

GAMSTOP covers online sites and apps. Betting shops use a separate, shop-based self-exclusion scheme rather than the GAMSTOP register, so an online self-exclusion does not stop a customer walking into a Ladbrokes shop. The two systems do not talk to each other, which is a structural limit on what GAMSTOP can do.

A financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025). The check is a public-record look-up — bankruptcy and county-court judgments, for example — and not an income, credit or affordability check. The financial risk assessments announced in a Commission article of 7 July 2026 are a separate, staged plan with no start date and should not be written about as in force.

Deposit limits (RTS 12) are a customer choice at every GB-licensed brand: operators must offer a gross deposit limit on a fixed time frame, the first changes have applied since 31 October 2025 and a second phase was postponed to 30 September 2026. Limits are not state-set and there is no state-set deposit or loss ceiling for betting. Help: GamCare runs the National Gambling Helpline; GambleAware and the NHS gambling clinics take referrals; Gamblers Anonymous runs local groups.

A Super Heinz costs 120 times the unit stake to place. A £2-per-line Super Heinz is a £240 outlay in one tap of the bet-slip button, and the difference between a £2 and a £5 unit stake is £360 of additional outlay across the 120 combinations. The bettor who sets a deposit limit needs to think of a Super Heinz as a single deposit event of £60 at 50p, £240 at £2 or £600 at £5, not as “120 separate bets” — the 120 lines are settled together and the stake hits the deposit ledger as one transaction.

Bonuses, Free Bets and the Super Heinz

Promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x: a £10 bonus at 50x needs £500 of bets; under the cap no more than £100 of bonus can attract the requirement. The cap applies to wagering conditions, not to free bets with no rollover attached, and the position of a free bet with stake not returned at the end of an offer is not established under the cap. Mixed-product promotions — an offer that asks the customer to gamble on two or more product types such as betting, casino, bingo and lottery — are banned outright, so a “bet on football to get free spins” structure cannot be sold at a GB-licensed brand.

Credit cards are banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2), and the ban covers credit-card-funded payments through an e-wallet; debit-card and bank-based payments are not affected. NetBet’s Daily Boosts and Profit Boosts, BetMGM’s four-token welcome bundle and QuinnBet’s 7-day free bets are paid as credits into a sports account, not as coupon-style vouchers.

QuinnBet’s terms set the most explicit framework on the shortlist for a Super Heinz: free bets are valid 7 days from credit, can be used on any market at odds of 1/2 (1.5) or greater, allow straight accumulators but ban Trixies, Patents and Yankees, with maximum odds of 50/1. A Super Heinz sits between a Yankee (11 bets) and a Goliath (247 bets), and the rule that bans those three bets casts doubt on whether the Super Heinz itself qualifies under QuinnBet’s terms — the slug of the bet type list rather than its length is the operative feature. A bettor with QuinnBet free-bet credit should check the current terms before building a Super Heinz.

Every welcome offer on the shortlist carries its own opt-in, its own minimum odds and its own expiry, and a Super Heinz built on welcome credit is settled as 120 separate bets with one stake-not-returned token split across them in the manner the operator defines. The 10x bonus cap does not apply to a stake-not-returned free bet with no rollover, which is how most sports welcome offers on the shortlist are written — BetMGM’s four tokens do not carry a wagering requirement, they carry a minimum-odds rule and a 7-day expiry. The 10x cap bites on bonus credit, not free bet credit, and the welcome offers on the shortlist are mostly written in free-bet form rather than bonus form.

Strategy and Tips Around a Super Heinz

A Super Heinz pays out on any two-selection combination that wins, which makes it a bet type that produces a return on most seven-leg tickets — but the size of the return swings wildly with the number of winners, and the stake cost is fixed at 120 units. The strategy is not about picking winners, since no system can. It is about choosing the unit stake that matches the bankroll and the selection profile that keeps the expected loss under the stake. A short price on every leg makes the bet small-staked and heavy on combinations, while a longshot on each leg makes the bet large-staked and rarely returns more than the smallest multiples.

There are no “tips” for picking winners — that outcome is unknown before the race finishes, and any system claiming to beat the bookmaker’s margin is testing a market, not a method. What a punter can do is choose what their edge is built from: prices that beat the market average (Fitzwilliam’s whole pitch is Oddschecker-averaged prices ), liquidity that beats the headline line (Matchbook’s exchange ), a feature that saves a broken leg (Betfred’s Sub Switch ), a boost that is genuinely free (BetMGM’s free bets with no rollover ) or a price-boost that triggers on the right bet (Kwiff’s Supercharge ). Each one is a different kind of value, and none of them makes a losing Super Heinz into a winning one.

A Super Heinz on seven short-priced favourites is a different bet from a Super Heinz on seven mid-priced selections. With seven favourites at 1/2 (1.50), the seven-fold returns about 17 times the unit stake, the doubles return at the same 1.50 price, and the bet’s main risk is that two or three favourites lose on the same day — which is a real risk on a Saturday football card. With seven mid-priced selections at 6/4 (2.50), the seven-fold returns over £600 on a £1 unit stake, but five of the seven need to win for the return to beat the £120 outlay, which is a tall order. The shape of the return is the shape of the price ladder.

Bet Types, Odds and the Super Heinz Settlement

A Super Heinz contains only multiples — doubles and up — with no singles. It differs from a Lucky 63 (six selections, 63 bets, includes six singles) and from a Heinz (six selections, 57 bets, no singles) by one rung each way. A Super Heinz with one selection voided still contains 57-bet Heinzes on the six remaining selections, plus the other combinations those six can produce — a useful way to think about how a partial loss settles, since the remaining 119 bets demote around the voided leg rather than vanish.

Odds are stated in either fractional or decimal form. A Super Heinz on a bookmaker slip is priced by the bookmaker, with a margin built into every leg. A market’s margin — sometimes called the overround — is what the bookmaker keeps per unit staked: if the back and lay of a two-selection match add up to 110%, the margin is 10%, the bettor’s payout share is 90%, and across a Super Heinz the margin compounds on every combination. On a heavily-margin market, a Super Heinz’s expected return sits well below the headline gross return; on a tightly-priced market, the gap narrows. The fairest way to compare operators on a Super Heinz is on the margin, not the headline price.

Void selections in a multiple settle to the next-lowest combination on the survivors. A treble with one void leg settles as a double on the two live winners; an accumulator with one void leg settles as a six-fold on the survivors of a seven-fold. Non-runner rules on horse racing, player-change rules on football and player-withdrawal rules on tennis are written into each operator’s settlement terms, and the Super Heinz inherits whichever non-runner, Rule 4 or voided-selection policy the operator applies to its multiples.

Responsible Gambling Around the Shortlist

Ladbrokes, BetMGM, NetBet, Fitzwilliam Sports, Fitzdares, Kwiff, Octobet, Matchbook, Betfred and QuinnBet are the ten operators on the shortlist. Every one of them is licensed by the Gambling Commission and enrolled in GAMSTOP. The Commission’s public register is the test of whether the licence is current, and the licence number is the search term: 54743 for Ladbrokes, 39198 for BetMGM, 39170 for NetBet, 48760 for Fitzwilliam Sports, 400 for Fitzdares, 44448 for Kwiff, 62545 for Octobet, 39504 for Matchbook, 39544 for Betfred and 61011 for QuinnBet.

The Commission’s public register can be searched by business name, trading name, domain or account number and lists every current licence alongside its categories. A licence marked “remote general betting standard (real events)” is the right category for a fixed-odds sports bookmaker; “remote betting intermediary” is the betting-exchange category and applies to Matchbook; the other nine operators hold the standard category. A search by domain shows the trading face behind the licence and the legal party that holds it — for example, a search of Ladbrokes’ domain returns LC International Limited as the licensee, not Ladbrokes itself.

A licence comes with obligations, not guarantees. GAMSTOP coverage, the 10x bonus cap, mandatory affordability look-ups in defined circumstances and the credit-card ban are the structural protections that attach to a GB licence; an unlicensed brand has none of them. The trade-off for those protections is verification before the first stake, which is mandatory and not optional. A punter who objects to verifying their name and date of birth has chosen a category of operator that the Act does not regulate, and the protections on this page do not apply there.

Frequently Asked Questions About the Super Heinz

What is a Super Heinz bet?

A Super Heinz is a full-cover combination bet on seven selections, covering every multiple from two selections up — 21 doubles, 35 trebles, 35 four-folds, 21 five-folds, 7 six-folds and 1 seven-fold, totalling 120 bets, with no singles standing alone. The unit stake is multiplied by 120, so a £2-per-line Super Heinz costs £240, and the bet pays out on any combination of at least two winners among the seven.

What is a Heinz bet?

A Heinz is a full-cover combination bet on six selections, covering every multiple from two selections up — 15 doubles, 20 trebles, 15 four-folds, 6 five-folds and 1 six-fold, totalling 57 bets, with no singles. It sits one rung below the Super Heinz (seven selections, 120 bets) and one above the Canadian or Super Yankee (five selections, 26 bets). The arithmetic is the binomial coefficient C(6, k) summed over k from 2 to 6.

How many bets are in a Super Heinz?

A Super Heinz contains 120 bets: 21 doubles, 35 trebles, 35 four-folds, 21 five-folds, 7 six-folds and 1 seven-fold. The number comes from summing the binomial coefficient C(7, k) for k from 2 to 6: C(7, 2) = 21, C(7, 3) = 35, C(7, 4) = 35, C(7, 5) = 21, C(7, 6) = 7 and C(7, 7) = 1, summing to 120. There are no singles in a Super Heinz — only multiples of two selections or more.

How can a bookmaker’s Gambling Commission licence be checked?

The Commission’s public register can be searched by business name, trading name, domain or account number at the regulator’s own site, and a successful search returns the licence categories, the licensee and a current status. Every operator on this page’s shortlist holds a current licence, and the search term is the account number: 54743 for Ladbrokes, 39198 for BetMGM, 39170 for NetBet, 48760 for Fitzwilliam Sports, 400 for Fitzdares, 44448 for Kwiff, 62545 for Octobet, 39504 for Matchbook, 39544 for Betfred and 61011 for QuinnBet. A registered domain proves nothing by itself, since licensed operators use both .com and .co.uk, and a registered address in Malta or Gibraltar does not disqualify a brand from holding a GB licence.

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

For any single bet, the return is the stake multiplied by the decimal odds, and the net profit is the stake multiplied by (decimal odds minus 1); for fractional odds a/b, the decimal odds are a/b + 1, so a £10 stake at 5/1 (6.00) returns £60 and yields a £50 profit. For a combination bet, the odds of the legs multiply into one price, so a double at 5/1 and 4/1 settles at 6.00 × 5.00 = 30.00, and a £10 double returns £300. A Super Heinz’s seven-fold multiplies all seven prices; the 21 doubles, 35 trebles and the larger multiples each multiply their own subset of prices, and the unit stake is the per-line stake across all 120 combinations.

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

The bookmaker’s margin is the share of every unit staked that the bookmaker keeps on average, calculated as 1 minus the payout share of a market. For a two-outcome market with decimal odds o₁ and o₂, the payout share is 1 ÷ (1/o₁ + 1/o₂) and the margin is 1 minus that figure; on a 1X2 football market at 2.10, 3.40 and 3.60 decimal, the payout share is about 95% and the margin about 5%. A margin of 5% compounds through a Super Heinz’s 120 combinations, which is why the expected return on a Super Heinz sits well below the gross headline of every combination winning. The most accurate way to compare bookmakers on a Super Heinz is on the margin of each leg’s market, not on the headline price.
