Highest payout online casino Australia: what the percentage actually buys you

Every comparison page in this corner of the web leads with a number. Ninety-six percent. Ninety-eight. A figure floating above the brand logo, untethered from any game, any studio or any measurement window. The number is the headline, and the headline is the pitch: deposit here, the maths is on your side.

The maths, in the Australian case, has a problem the headline never names. The Interactive Gambling Act 2001 makes it an offence to supply online casino games or online pokies to a person physically in Australia, and no state or territory licenses that product. Whatever licence a site flashes on its footer, no matter which offshore regulator issued it, the service is still prohibited for an Australian customer. A percentage advertised by an offshore operator is, for anyone playing from Sydney, Perth, Brisbane or a small town in between, a number attached to a product the law says they cannot lawfully be sold.

This page is not a leaderboard of which offshore brand has the kindest looking return-to-player figure. It is a working through of what that percentage actually measures, what it does not, what it costs a player who acts on it, and what the regulator is doing about the 11 brands the Australian Communications and Media Authority has named in formal warnings over the past four years. The angle is cost — what the offer is worth once the marketing is stripped off, what the mechanism takes from the punter, and what a session actually looks like under the rules the operator does publish.

Current as of 18 October 2026 · Verified against the Australian Communications and Media Authority formal warning register.

What the ACMA has actually been doing in 2026

The ACMA does not publish a leaderboard. It issues formal warnings, asks ISPs to block domains, and on a slow news day names the next dozen sites to disappear from Australian connections. The shape of that activity is the closest thing to a public scorecard for offshore operators who take Australian customers.

In a single round reported on 26 June 2026, the ACMA asked Australian internet service providers to block 12 more illegal gambling websites: 7Signs, ChromaBet, Donbet, Duospin, Freshbet, Slots Gem, Jacks Club, Lucky Start, Pointsbetz.com, Spinrise, Vinyl Casino and Wildsino. That round sat inside a running total: 1,751 illegal gambling and affiliate marketing websites blocked since the first blocking request in November 2019, and more than 230 unlicensed gambling services that had simply left the Australian market since the regulator sharpened its enforcement in 2017.

The rate is what makes the picture. Roughly 80 months between November 2019 and the end of the period reported in June 2026, taking out about 1,751 blocking actions across illegal sites and affiliate marketing pages. That arithmetic is not the regulator’s own number; it is what falls out of the totals research carries. The cleanest reading is a band rather than a single line: between roughly 20 and 25 sites blocked each month on average over the period, with the monthly pace climbing in the rounds reported through 2025 and the first half of 2026. The condition matters — the figure counts blocking actions, not unique operators, and a single brand sitting on a dozen mirror domains can populate several rows of the running total.

The economic backdrop is what gives those blocks their weight. H2 Gambling Capital’s 2025 estimate puts Australian losses to illegal gambling sites at about A$3.9 billion a year, with the share of gambling going through legal channels falling from 74% in 2021 to 64% in the most recent year reported. The illegal book is growing against a legal book that is shrinking as a share of the whole, which is the reverse of what the policy aims for and the reason the ACMA keeps adding names to the block list.

The licensed landscape, briefly

There is one Australian online wagering licence set worth knowing about, and it is the one the ACMA does not block. The Northern Territory Racing and Wagering Commission regulates 52 of Australia’s online bookmakers — including Sportsbet, Bet365 and Ladbrokes — and the licence exists for tax reasons rather than for consumer protection. The commission has no full-time staff and meets once a month in Darwin. Its job is to collect the Territory’s share of the wagering tax; the conduct rules are largely set by the federal regime. A “licensed” badge on an Australian-facing sports or racing book is real; a “licensed” badge on an Australian-facing casino is, by definition, not.

That is the legal frame in one line. The IGA permits wagering on races and sport placed before the event, lotteries and keno. It does not permit online casino games, online pokies or in-play betting, and no state or territory has stepped in to license them. Minimum age is 18. The player is not the target of prosecution; the operator is. That distinction does the punter no good when a withdrawal is refused, because an offshore operator gives no Australian complaints body and no enforceable right of recourse.

How an offshore casino’s payout percentage is actually measured

Return-to-player, or RTP, is the share of every dollar a game takes in that it returns to players over a long run. A 96% slot keeps, on average, four cents of every dollar wagered; the other 96 cents cycles back to the players who played it. That figure is a property of the game — the maths programmed into the random number generator — not of the casino. The casino chooses which games to host; the studio designs the math.

The advertising word “highest payout” is doing something else again. The number on the landing page is usually an aggregate the operator has chosen to publish, often a trailing average across the games on its floor, sometimes a single title’s RTP pulled forward. Some brands publish a “theoretical payout” of 96% to 98% and never quite explain the window. None of them publish the data that would let a punter check it: a per-game spin log, an audit trail, a time-stamped settlement report. Independent testing houses — eCOGRA, GLI, iTech Labs — certify games in batches before release, but they do not run a live audit of every spin on every site. Once the game is live, the only RTP being measured is the one the operator chooses to share, if any.

That gap between the certified RTP and the RTP a player experiences in a session is not small and it is not a trick. A 96% slot over ten million spins will sit close to 96%. Over fifty spins on a Tuesday night, anything can happen, and the only honest reading of “highest payout” is a long-run average the player will never personally hit. The punter looking for the kindest odds is buying a number that describes a population, not themselves.

Why ranking by advertised payout percentage is the wrong question

Two reasons, and they are different.

The first is legal. An Australian resident playing at an unlicensed offshore casino is on a product the IGA says cannot be supplied to them. The highest payout number in the world does not change that. Ranking the brands by who advertises 98% rather than 96% is sorting the prohibited pile by a criterion the law has already rejected.

The second is structural. A 2% gap in headline RTP is real over millions of spins and invisible over a session. A player who deposits A$200, plays fifty spins at A$2 each on a 96% slot, has wagered A$100 and lost about A$4 on average — well inside the noise of variance. The same player on a 98% slot loses about A$2. The difference is two dollars, smaller than a single losing spin’s swing. Anyone choosing between two offshore casinos on the basis of that 2% has lost the comparison before they started, because the comparison is not the lever that decides what the session costs them. The bet size, the game choice, the session length, the bonus terms if any — those are the levers.

What “highest payout” costs the punter in practice

The marketing word is “magic.” The math is not. Three levers decide what a session actually costs, and none of them is the headline number on the landing page.

The first is the house edge. A 96% RTP is a 4% edge to the house, which is the operator’s structural margin on every dollar wagered. Across a session, the player is, on average, paying 4 cents per dollar in expected loss. The expected loss on a A$200 deposit played through a single time at a 96% slot is around A$8 — the player finishes with, on average, A$192 from a starting balance of A$200. The “highest payout” casino simply charges less for the privilege of doing this. It does not make the privilege profitable.

The second lever is the wagering requirement on any bonus. A deposit bonus is rarely free money; it is a loan with a turnover condition attached, and the condition is what decides what the bonus actually costs. A A$100 bonus with a 40x wagering requirement needs A$4,000 of play to clear, at which point the expected loss on the bonus portion alone, played at a 96% slot, is A$160. The bonus paid A$100; clearing it cost more than the bonus was worth, before the player ever touched the original deposit. The headline number is, again, the wrong lever.

The third lever is the maximum cashout cap. Some operators limit how much of a bonus can be withdrawn, regardless of how well the player runs. A A$100 bonus with a 5x maximum cashout caps the withdrawable bonus-derived winnings at A$500, no matter how the session goes. Beyond the cap, the rest is forfeit. A bonus that looks generous on paper can pay less than a smaller bonus without a cap, even when the play goes well.

Where ACMA enforcement actually lands on the brands you see advertised

The 11 operators on the warning register below share one feature: the ACMA has formally named each of them for supplying prohibited interactive gambling services to Australians. The warning register is not a ranking, and “highest payout” is not the criterion that put any of them on it. The criterion is the Interactive Gambling Act 2001, applied to a service that should not have been offered to an Australian customer in the first place.

The table that follows lists each brand in the order the ACMA register suggests, with the operator named by the regulator, the date of the formal warning, and what research was able to confirm about the brand’s own footprint on Australian-facing listings. Where research carries nothing, the row carries an honest gap rather than a guess.

The right reading of this table is not “which one pays out best.” The right reading is: every brand on it has been formally told by Australia’s internet regulator that the product it is selling cannot lawfully be sold to the reader sitting in front of this page. The subject-support column does not change that — it is what third-party listings say about how the brand operates, not the regulator’s view. Where research carries nothing for that column, the row stays blank rather than padded.

What the brands on this register actually have in common

Three threads run through the 11 entries.

The first is that no state or territory in Australia has issued a casino licence to any of them, and no offshore licence cures the gap. The IGA targets the act of supplying prohibited services to a person in Australia, not the licence the supplier holds elsewhere. A Curacao or Anjouan credential is irrelevant to whether the service is lawful here.

The second is that the operator named by the ACMA is often a corporate vehicle rather than the brand on the landing page. Dama N.V. appears three times in this register under three different brand names. Consolutetish S.R.L. appears twice. The relationship between corporate entity and player-facing brand is itself information: when a regulator warns the parent, the brand is what changes, not the operation. The same management can stand up a new domain and re-run the same product the regulator has already told them to stop.

The third thread is the breadth of the products. Casino games, online pokies, sometimes sports betting layered on top — every category the IGA prohibits has shown up in the regulator’s warnings. The illegal market is not a single product; it is a stack of them, and the ACMA has been working through the stack since 2017.

What a player at one of these sites cannot do if things go wrong

This is the part the marketing never reaches.

There is no Australian complaints body with jurisdiction over an offshore casino. The brand may belong to a dispute resolution service — eCOGRA or AskGamblers, for the ones that bother — and that service can rule against the player, but it cannot enforce its ruling against an operator that does not pay. The path from a refused withdrawal to a recovered balance runs through the operator’s own terms, and the operator wrote those terms.

There is no protection from BetStop, the National Self-Exclusion Register. BetStop binds Australian-licensed online and phone wagering services; an offshore casino is not connected to it, and a self-exclusion lodged with an offshore operator is only as good as that operator’s willingness to honour it. The legal exclusion regime and the offshore product do not talk to each other.

There is no recourse if the operator disappears. A blocked site can leave a player holding a balance they cannot withdraw, because the same offshore corporate vehicle that ran the site has no obligation to honour balances after the domain goes dark. The regulator’s job is to keep the site from reaching new Australian customers in the first place; the player’s existing balance is not the regulator’s problem.

What the bank side does to the offshore route

Australian banks have spent the last several years making the offshore route harder to walk, regardless of what the regulator does at the domain level.

Westpac’s gambling block works at card level and refuses authorisation of transactions registered under the merchant category code “Betting/Casino Gambling” on eligible personal credit and debit cards. ANZ’s gambling transaction block, activated inside the ANZ app, also blocks gambling transactions made through a digital wallet such as Apple Pay on an eligible card — not just the physical card — and once turned on, removing it again requires a 48-hour waiting period. Commonwealth Bank’s gambling lock, applied to eligible cards through the CommBank app, automatically blocks most gambling transactions, with the same caveat the other banks carry: it cannot guarantee every gambling-related purchase will be stopped.

The wallet side matters because of how Australians pay. By the end of 2025, Apple Pay, Google Pay and Samsung Pay transactions collectively accounted for around 45% of all card payments in Australia by number. ANZ’s block treats a digital-wallet transaction the same as a physical-card transaction when the underlying card is on the block list; Westpac’s block operates on the merchant category code, so it catches the same transaction wherever it is initiated from. A player who adds a card to Apple Pay and tries to deposit at an offshore casino is, in practical terms, asking the bank to say no on the way through.

The bank block is not the only friction. Under the Interactive Gambling Act 2001 as amended in 2023, Australian-licensed online wagering services cannot accept payment by credit card or other credit-related products, and the practical effect is that a player trying to deposit with a credit card at an offshore site is using a payment method the legal Australian market has already rejected. The offshore operator may accept it anyway; the Australian side of the transaction has already said no.

The payment rails that work for legal wagering — and what they mean for the illegal side

Australian-licensed wagering services take deposits through debit card, bank transfer, PayID/Osko and BPAY. Each of those rails has a property the illegal market would prefer to keep quiet.

PayID and Osko run on the New Payments Platform, owned by New Payments Platform Australia Ltd, a non-profit whose 13 shareholders include the Reserve Bank of Australia and the country’s major banks. With Osko, a bank transfer between participating Australian banks arrives in under a minute, 24/7 including weekends, addressed to either a BSB and account number or a PayID. PayID-based instant transfers are available at over 100 Australian financial institutions, and more than 25 million PayID identifiers had been registered on the platform as of April 2025. When a punter pays to a PayID, the name of the account holder appears before the transfer is sent; AP+ warns that being asked to transfer money to a PayID on an illegal gambling site almost certainly means a scam site.

BPAY is a bill-payment service in online banking, run by Australian Payments Plus. The payer enters the Biller Code and the Customer Reference Number printed on the bill, and BPAY has been operating since 18 November 1997, available in the online banking of over 140 banks and financial institutions and offered by over 95,000 businesses. Its parent company is Cardlink Services Limited, owned equally by ANZ, Commonwealth Bank, National Australia Bank and Westpac. The Australian Payments Plus merger in September 2021 brought BPAY Group, eftpos and NPP Australia under one holding company, and the platform is required to keep monthly outages to no more than two minutes.

The reason this matters for an offshore casino is that none of these rails are quietly anonymous. The transfer carries a name, an account, a BSB and a transaction record. AUSTRAC’s threshold-transaction-report rule, which requires reporting of transfers of A$10,000 or more, applies only to physical cash; ordinary electronic bank transfers are not subject to that per-transaction reporting requirement, regardless of the amount sent. But the bank still sees the transfer, and the bank already has the rules about where the money goes. A player who deposits through PayID at an offshore casino is depositing through a rail designed for a regulated market and using it for a product that is not.

What the high-payout comparison actually looks like when it is honest

Honesty on this subject has three parts.

The first is the legal status. An Australian resident cannot lawfully be supplied with online casino games by an offshore operator, and the operator cannot lawfully offer them. The product is prohibited, and no comparison of advertised payout percentages changes that. A page that leads with a leaderboard of the “highest payout” offshore casinos is leading with the wrong number.

The second is what the percentage measures. RTP is a long-run average across millions of spins on a single game, certified before the game goes live and not re-audited spin by spin. A “96% payout casino” is a casino whose house edge across the games on its floor is, on average, 4%. That is a small edge, a meaningful edge, and a structural edge — the punter is, on average, paying 4 cents per dollar played. The figure describes the population; the session is a sample of one.

The third is what the operator does not publish. Most offshore brands do not publish per-game, time-stamped RTPs. They do not publish live withdrawal statistics. They do not publish how many of the previous month’s withdrawals were refused, capped, or delayed past the advertised payout window. The “highest payout” leaderboard ranks on the only number the operator chooses to share, and the only numbers the operator does not share are the ones that would let a punter check it.

What a session on a high-payout slot actually costs in expected loss

Assume the punter plays a 96% slot at A$1 a spin for 200 spins. That is A$200 wagered. Expected loss, on average across many such sessions, is A$200 multiplied by (1 minus 0.96), which is A$8. The punter finishes with, on average, A$192 of the original A$200 still on the balance, having played through A$200 in wagers across 200 spins.

The same arithmetic on a 98% slot — the “highest payout” end of the marketing — gives an expected loss of A$200 multiplied by (1 minus 0.98), which is A$4. The headline gap between 96% and 98% is two percentage points of RTP; the dollar gap on a A$200 session is, on average, A$4.

That is the scale of the comparison the leaderboard is selling. A$4 across a session the punter will remember. A bonus with a 40x wagering requirement on a A$100 deposit would need A$4,000 of play to clear, at which point the expected loss on the bonus portion is roughly A$160 — forty times the gap the leaderboard ranks on. The lever the comparison asks the punter to pull on is the smallest lever in the room.

Responsible gambling: what the percentage does not do

A high advertised payout rate is not a reason to deposit more, chase a loss, or run a session longer than planned. It does not change the variance of any individual session. It does not change the probability of winning any single spin. It does not protect a balance from a maximum cashout cap on a bonus. It does not give a player an Australian complaints path if the operator refuses a withdrawal. It does not connect the player to BetStop. It does not undo the Interactive Gambling Act 2001.

The National Gambling Helpline is 1800 858 858, free and 24/7, with chat at Gambling Help Online. BetStop, the National Self-Exclusion Register, has been live since August 2023 for Australian-licensed wagering services. For anyone whose gambling has stopped being a choice, those are the numbers that matter; the percentage on the offshore landing page is not.

How the regulator’s pace is changing

Two years ago the ACMA’s monthly pace of blocking actions was lower than the figure the 1,751-site total implies. The reported rounds of 2025 and 2026 have been heavier, the lists of named brands have been longer, and the operator vehicles have appeared more than once under different brand names. The block is becoming more routine, not less.

The reform timetable matters. The Interactive Gambling Amendment (Gambling Reform) Bill 2026 passed Parliament on 19 August 2026, and its advertising and inducement measures commence on 1 January 2027. On a 2026 page, that is a law that has been passed but has not yet commenced — a future tightening, not a current rule. The player reading the page now is governed by the law as it stands, which is the version that already prohibits the product.

Tax position for an Australian recreational player

Winnings of a recreational player are not assessable income, under section 6-5 of the ITAA 1997, and losses are not deductible — unless the person carries on a business of gambling. That is the model answer and it is the right one for almost everyone reading a comparison page. Anyone whose gambling has crossed the line into a business should be checking with the ATO rather than reading this paragraph.

Where the rest of the iGaming rule book sits

A few notes that do not fit anywhere above and matter for the Australian case.

American Express was established in 1850 as a freight-forwarding company, launched its first charge card on 1 October 1958 and runs as a three-party scheme — issuer, network and merchant in one — unlike Visa and Mastercard’s four-party model. The Reserve Bank of Australia’s July 2025 review proposes removing surcharges only on eftpos, Mastercard and Visa card transactions, leaving American Express outside the proposed surcharge ban. None of that makes an Amex deposit at an offshore casino lawful; it makes the surcharge arithmetic at a legal merchant different from the surcharge arithmetic at a card with interchange regulation. The IGA position is unchanged.

Apple does not charge Australian consumers for using Apple Pay in stores, online or in apps; any surcharge comes from the merchant’s card-processing fees, not from Apple. Apple also states that transaction limits and PIN requirements for Apple Pay purchases are set by the card issuer or merchant, not by Apple. The wallet is a rail; the rules come from the bank and the merchant. The bank already has the gambling block, and the merchant is the offshore casino the IGA has already addressed.

The eleven brands, one verdict each

Each brand below has been formally named by the ACMA for supplying prohibited interactive gambling services to Australians. The verdict is the same in every case: the service is unlawful for an Australian customer, and the advertised payout percentage does not change that. What differs between them is the regulatory history — the date of the warning, the corporate vehicle behind the brand, and what research was able to confirm about the brand’s footprint.

RocketPlay

The ACMA issued a formal warning to Pulsup Ltd over Rocketplay.com.au in March 2026, sitting on top of an earlier warning to Dama N.V. over the brand in May 2022. Gambling Insider listings describe it as a Curacao-licensed operator that has accepted Australian play; that is what the listing says, and the IGA position is what it is. The verdict is the one the regulator has already published: the service cannot lawfully be supplied to an Australian customer, and the corporate vehicle behind the brand has been through this conversation before.

Level Up Casino

The ACMA’s warning to Dama N.V. over Level Up Casino dates to May 2022, one of six Dama brands named in the same round. Westpac’s gambling block excludes Westpac-issued card transactions to this brand under the betting and casino MCC, which is one reason the brand has been harder to reach from a Westpac account since the block went live. The brand’s standing on the warning register is the standing the verdict addresses.

Woo Casino

The ACMA issued a further formal warning to Dama N.V. over Woo Casino in March 2025. This was an additional warning for a parent entity that had already faced regulatory scrutiny, marking this brand as part of a recurring pattern rather than an isolated incident for Dama N.V. Our assessment remains that this service is unauthorized for Australian customers.

Spirit Casino

The ACMA issued a formal warning to Dama N.V. over Spirit Casino in May 2025, just two months after the Woo Casino warning. Because Dama N.V. has been named by the ACMA multiple times for offering prohibited services, this brand falls firmly into the category of services that cannot be supplied to Australians. We maintain the regulatory conclusion that this is an unlawful offer.

National Casino

The ACMA issued a formal warning to Consolutetish S.R.L. over National Casino in July 2025, as part of a round that also named Bizzo Casino and Ignition Casino. Regulatory bodies including AUSTRAC and BetStop have also referenced this brand, suggesting a level of official scrutiny that exceeds many other offshore sites. Given this history, the service remains unequivocally blocked for Australian players.

Bizzo Casino

The ACMA issued a formal warning to Consolutetish S.R.L. over Bizzo Casino in July 2025, on top of an earlier 2022 warning to TechSolutions (CY) Group Limited and TechSolutions Group N.V. over the same brand. Gambling Insider listings describe it as a Curacao-licensed operator accepting Australian play. Two warnings, two corporate vehicles, one brand — that is the history the verdict sits on.

Ignition Casino

The ACMA issued a formal warning to Bamboo Media over Ignition Casino in July 2025. The brand’s footprint in Australian-facing listings is the thinnest of the three named in the same round, and the verdict is the regulatory one the ACMA has already published.

Instant Casino

The ACMA issued a formal warning to EOD Code SRL over Instant Casino in February 2025. Third-party sites have sometimes cited the availability of payment rails like PayID or ecoPayz as a convenience feature, but these methods are irrelevant to the legality of the service under the IGA. The regulator’s position is definitive: this service is not permitted for use by Australians.

Jackbit

The ACMA issued a formal warning to Ryker B.V. over Jackbit in April 2026, representing the most recent enforcement action on our list. This inclusion underscores that the regulator is actively expanding its efforts to curb offshore supply. Regardless of its recent marketing or site features, Jackbit does not possess a valid Australian licence for the services it offers.

Casino Intense

The ACMA issued a formal warning to Sterplay Holding Ltd over Casino Intense in April 2025. With official references from both AUSTRAC and BetStop, this operator has drawn significant attention from multiple Australian regulatory channels. As with all other brands on this list, it cannot lawfully accept Australian business.

Sky Crown

The ACMA issued a formal warning to Hollycorn N.V. over its Sky Crown and Blue Leo casino services, as published in the formal warning PDF dated September 2022. The verdict is the same as the others, and the dual-brand warning is the one feature worth noting.

What the comparison actually tells a reader who arrived looking for the highest payout

Three things, and they are not all the answer the reader came for.

The first is that the comparison has been made on a forbidden field. Ranking offshore casinos by advertised payout percentage is sorting the prohibited pile by a criterion the IGA has already excluded. The honest leaderboard of Australian online gambling is the legal wagering market — sports, racing, lotteries, keno — and the legal market does not offer the product the reader came here to compare.

The second is that the gap the reader came to measure is smaller than the marketing makes it look. A 2% RTP gap on a A$200 session is, on average, A$4. The levers that decide what the session costs are bet size, game choice, session length, and the terms of any bonus attached. None of those is on the landing page, all of them are inside the operator’s terms, and none of them is what the leaderboard ranks on.

The third is that the ACMA has already done the comparison that matters. Eleven brands, formal warnings, a regulator’s view that the product is unlawful. The leaderboard the regulator keeps is the only one that ends with an answer a reader can act on, and the answer is that none of the eleven are a lawful place for an Australian customer to play.

Frequently asked questions about payout percentages and Australian online casinos

What does a casino’s advertised payout percentage actually measure?

It measures the share of every dollar a game takes in that it returns to players over a long run, expressed as a percentage. A 96% slot keeps, on average, four cents of every dollar wagered. The number is a property of the game’s design — the maths programmed into the random number generator — not a guarantee of what any single session will pay back.

Does a high return-to-player rate mean a player is more likely to win on any single spin?

No. Each spin is independent, and the long-run average does not change the odds of any individual outcome. A 98% slot is not “more likely to pay” on the next spin than a 96% slot. The percentage describes what happens across millions of spins, not what happens on the next one.

How is an online casino’s payout rate different from a single game’s house edge?

They are two sides of the same coin. The house edge is 100% minus the RTP: a 96% RTP is a 4% edge to the house. The casino’s “payout rate” is usually an aggregate across the games it hosts; a single game’s house edge is the figure published for that title.

Can an advertised payout percentage be independently verified by a player?

Not in real time. Independent testing houses such as eCOGRA, GLI and iTech Labs certify games in batches before release, but they do not run a live audit of every spin on every site. The only RTP being measured after the game is live is the one the operator chooses to publish, if any. The data a player would need to check it is not shared.

Why might a game’s real-world payout differ from its advertised long-run average?

Because the long-run average is taken across millions of spins. Across fifty spins on a Tuesday night, anything can happen, and the actual payout for that session can sit well above or well below the long-run figure. Variance is not a bug; it is the shape of the game over a short window. A punter choosing a session length that lets the long-run figure come through is the only practical way to bring the two closer together — and a longer session also costs more in expected loss.
