£3 Minimum Deposit Casino UK: Where £3 Works and How to Make It Last (October 2026)

Quick answer: finding a £3 deposit casino and making £3 last

• Confirm £3 on the method you will pay with. The casino’s cashier floor and the payment method’s own floor both have to allow £3, and they can differ on one site. Read the payments help page before registering and the cashier after.
• Play 10p, not 20p. Three pounds is 30 stakes at 10p and 15 at 20p. On four model slots the higher stake cut the median session from 53 to 160 spins down to 22 to 52, and it did not lift the chance of touching £10.
• Check the RTP version before the stake. An hour of Book of Dead at 10p costs £2.27 on average at its 96.21% default and about £9.48 at its lowest version, a wider gap than doubling the stake creates.
• Know what the ranked offers ask for. The casinos ranked above are licensed offshore, beyond GamStop and the UK complaints route, and their packages start at £20 or €20 with wagering of 35x to 40x, so £3 does not qualify for any of them.
• The catch: a doubled £3 is still only £6. Reaching a £10 minimum withdrawal means more than tripling the deposit, which happened in 9.7% to 17.6% of simulated sessions at 10p, so check before paying in whether a smaller balance can be withdrawn in full.

A £3 deposit works at any licensed site whose cashier and payment method both take it. The Gambling Commission sets no minimum deposit. Casinos choose their own, payment methods can add theirs, and the two can differ on a single site, so the figure that counts is the one the cashier shows for the method you intend to use, read together with that method’s terms.

Three pounds converts into very different amounts of play depending on the stake: 30 spins at 10p, 15 at 20p, six at 50p or three at £1, before any winnings come back. At bingo it is thirty 10p tickets. At a roulette table it is three £1 bets, and three bets on red leave you ahead 48.0% of the time (two or three wins; exact for a single-zero wheel).

The rules that come with a licence do not shrink with the deposit. Age and identity are verified before any play, a deposit limit is offered before the first payment, credit cards are refused, cryptocurrency is in practice not offered, and any bonus attached to a small deposit is capped at 10x wagering and cannot require a sports bet.

Offshore sites target the same search with large percentage matches and “not on GamStop” marketing. They are not licensed in Great Britain, and the offshore section shows why a big match on £3 at offshore wagering has a negative value on the standard formula before any of the lost protections are counted.

What to compare on each £3 minimum deposit casino

Once a cashier accepts £3, the site’s other settings decide whether that money means thirty chances or fifteen, and whether anything it wins can be collected. Set these lines side by side for any two casinos you are weighing up; the figures come from this page’s simulations and price tables.

Rows two and three move the money most. The 10p stake gave roughly two and a half to three times as much play as 20p for the same £3, and a default RTP version keeps the hourly cost at a fraction of a low one. Neither choice costs anything, and neither features in casino advertising.

The fourth row is why the ranking above is a separate decision: its packages are built for £20 or €20 and up, and their play-through is priced in the offshore section. On £3 the questions are the cashier floor, the stake and the game.

10p or 20p: the stake that makes £3 last

A slot stake turns £3 into a number of chances. That number matters more than it looks, because a small balance survives on the count of stakes it holds rather than on its value in pounds. Staking the £3 once costs the same at any stake, 12p on average on a 96% slot; what the stake changes is how the money is sliced and how long the slices last.

How many spins £3 gives you at each stake

Read down the table and the trade is plain. Every row costs 12p on average for one pass through the money. The smaller the stake, the more spins those 12p are spread across, the longer the play and the better the chance of meeting a bonus round, the feature that holds most of a model slot’s big payouts. Each bonus-round figure is the complement of drawing a blank on every spin, at each model’s frequency: about 1 in 170 spins on Model A, 1 in 200 on B, 1 in 180 on C and 1 in 120 on D.

£3 at 10p against 20p: 40,000 simulated sessions per model and stake

Real play does not stop after one pass. Wins come back and get staked again until the balance can no longer cover a spin. The bankroll simulation followed exactly that, 40,000 sessions for each row, playing at one fixed stake until the money ran out or 1,440 spins had passed, the most the legal pace allows in sixty minutes. The four model slots differ in volatility, the spread of results around the average: Model A is medium at 96% RTP (return to player), Model B high at 96.21% and built to resemble Book of Dead, Model C medium-high at 96.71% and built to resemble Big Bass Bonanza, Model D low at 96%. None is a copy of a real game; real pay tables are not published.

What the lower stake gains you, and what it does not

The length of play changed most. Moving from 10p to 20p shortened the median session by 58% on Model B, 60% on A, 61% on C and 68% on D. After 50 spins, roughly seven in ten 10p sessions on Models A and C were still going, against one in four at 20p. After 100 spins the 10p sessions were also more often ahead, 14.3% to 33.9% against 7.7% to 23.8%, simply because most 20p sessions no longer existed by then.

The upside barely changed. The chance of touching £10 was identical on Model A (10.4% at both stakes) and between 0.6 and 1.0 percentage points lower at 20p on the other three. Doubling to £6 followed the same pattern. On no model did the larger stake improve either figure.

So the two stakes buy the same small chance of a withdrawable £10 at very different prices in time. If the deposit is meant to be played, 10p gives roughly two and a half to three times as much play for the same money. If the only aim were a quick result, 20p delivers that result sooner, and it is no more likely to be a good one.

How many minutes your £3 lasts

The assumed pace of 600 spins an hour, a spin each six seconds, sits close to what the official figures imply: the average session in January to March 2026 ran to 124 spins in 15 minutes, about one spin every seven seconds. On that basis a typical £3 session at 10p lasts somewhere between about five and sixteen minutes, and at 20p between about two and five.

Why a bigger stake will not improve your odds

Two effects pull against each other. A bigger stake means fewer spins to reach any target, and fewer spins means less of the house edge paid along the way, which on its own would raise the chance of getting to £10. But a balance only 15 stakes deep is more likely to run dry before a bonus round turns up: in 15 spins the round arrives 7.2% to 11.8% of the time on the four models, against 14.0% to 22.2% in 30. In the simulation those effects roughly cancelled, leaving the 20p sessions level with or slightly behind the 10p sessions.

There is also a fixed ceiling that both stakes share. On any game that pays back 100% or less, the average balance cannot rise above the £3 that started it, so the chance of touching £10 can never exceed three in ten, whatever the stake or system. Both stakes landed well under that ceiling and close to each other.

Pick the RTP version first: it can matter more than the stake

The stake is one dial on the cost of play; the version of the game is another, and often the bigger one. Several slots are supplied by their providers in more than one RTP version, and the version a casino runs appears in the game’s information screen. This page does not say which version any casino uses. The table prices an hour of play at an assumed 600 spins, at the default version and at the lowest version each provider lists.

Doubling the stake doubles the hourly cost. Dropping from a default version to the lowest can do far more: on Book of Dead the 10p hour rises from £2.27 to about £9.48, more than four times as much. A player at 20p on a default version therefore pays less per hour than a player at 10p on the lowest Book of Dead, Rainbow Riches or Wanted Dead or a Wild version. For £3 the practical rule is to check the information screen first and the stake second. How RTP, volatility and versions work across the catalogue is explained in the guide to online slots in the UK.

Bingo and roulette: other ways to spend £3

Away from slots the same £3 behaves differently. Thirty 10p bingo tickets can be spread thin or bunched. Six tickets a game for five games in a room of 50 tickets gave a 31.0% chance of a prize in each game in the 90-ball simulation, so about 16% of the time no prize would come in all five; one ticket a game stretches the same £3 across thirty games, which is about two and a half hours at an assumed 12 games an hour. Either way the long-run return is the room’s payback, illustrated here at 70% to 90%, so £2.10 to £2.70 back from £3 on average. Prizes are set by the room rather than an RTP, and under the Commission’s standard RTS 3 a bingo operator may publish how prizes are allocated in place of an RTP figure.

Roulette slices £3 into three £1 bets at most, with exact chances on a single-zero wheel. Three bets on red win all three times 11.5% of the time (£6 back), twice 36.5% (£4), once 38.5% (£2) and never 13.5%. Being ahead 48.0% of the time is a high figure because three bets give a 2.70% edge almost no time to work. The price is a session that lasts three spins of the wheel. UK stake limits and the 2.5-second rule do not apply at the table at all; the table’s own minimum decides whether a £1 bet is possible.

Make £3 go further: count it in stakes, not pounds

The simulation ran fourteen combinations of starting balance and stake on each model slot, and one pattern runs through all of them that is worth more than any single row: balances holding the same number of stakes behave alike, whatever they are worth in pounds. £1 at 10p, £5 at 50p and £10 at £1 all hold ten stakes, and on Model A all three lasted a median of 16 spins. £5 at 10p and £10 at 20p both hold fifty, and both lasted 135.

Two lessons follow. The first is that the stake works as the divisor of the deposit: halving the stake does to a balance’s life exactly what doubling the money would. £3 at 10p is a 30-stake balance and behaved like one; £3 at 20p is a 15-stake balance, which puts it much nearer to a single pound at 10p than to £5 at 20p. Choosing 20p does not turn £3 into a bigger deposit. It turns it into a smaller one.

The second is that life grows faster than the stakes do. On Model A a 10-stake balance lasted 1.6 spins for each stake it held, a 30-stake balance 2.3, a 50-stake balance 2.7 and a 100-stake balance 3.4. A deeper balance rides out the dry runs between wins, so more of the slot’s frequent small returns get recycled into further spins instead of arriving after the money has gone. That is why the gap between 15 and 30 stakes, the whole difference between 20p and 10p on £3, is worth more than double the play.

The same arithmetic explains why the chance of touching £10 hardly moved with the stake. Measured in stakes, the target shrinks along with the balance: from 30 stakes to 100 at 10p, from 15 to 50 at 20p. The ratio is three to ten either way, so both share a ceiling of 30% and both land a long way beneath it, close together.

Is £5 or £10 worth it over £3? What each extra pound buys

The other lever is the deposit itself. The 10p rows for £1, £3, £5 and £10 show what each extra pound buys, measured three ways: the chance of touching £10, the length of the session and the chance of doubling. All figures come from the same 40,000-session runs per model.

What each extra pound adds to your chance of £10

Each pound added between £1 and £5 lifted the chance of touching £10 by roughly 3.3 to 4.5 percentage points on Models A to C and 6.3 to 6.4 on Model D, against a ceiling that rises by 10 points for every pound. On every model the second pair of pounds bought a little more than the first, because a deeper balance stays alive long enough for more of its chances to land. A £10 deposit leaves this question behind, since it starts at £10.

How much longer each extra pound plays

Here the returns grow with every step, which is the stakes pattern again seen from the deposit side. On Model A £3 lasted 22.7 median spins per pound deposited and £10 lasted 33.6. At the 2.5-second minimum that is the difference between a median session of 2 minutes 50 seconds and one of 14 minutes; at an assumed 600 spins an hour, between 6 minutes 48 seconds and 33 minutes 36 seconds. Longer is not cheaper, though. A session that lasts longer pays the edge on more spins, and every extra pound deposited is an extra pound at risk.

Your chance of doubling from £3, £5 and £10

The chance of doubling barely depends on the size of the deposit: about one in five on Models A and C, a little less on B, close to three in ten on D. Model D’s £10 figure is held down by the simulation’s one-hour limit rather than by the game, because 38.7% of those sessions were still playing when the 1,440 spins ran out, many of them without ever having doubled. What the deposit changes is what a double is worth. A doubled £3 is £6, still short of a £10 minimum withdrawal; a doubled £5 is exactly £10; a doubled £10 is £20.

Your chance of being ahead after 100 and 500 spins

One more comparison separates time from odds. On Model A the share of sessions ahead after 100 spins was 17.9% from £3, 22.2% from £5 and 22.9% from £10; on Model D, 33.9%, 35.0% and 34.9%. Beyond £5, more money did not make a session more likely to be ahead at that point. After 500 spins the picture changes, 6.7%, 10.7% and 19.0% on Model A, because the smaller balances had mostly gone bust by then. Extra pounds buy survival, not a better position at any given moment.

Reaching a £10 minimum withdrawal from £3, £5 or £10

Taking £10 as the example minimum, the three measures line up like this. A £3 deposit must more than triple to reach it, and touched £10 in 9.7% to 17.6% of simulated sessions at 10p. A £5 deposit must double, which it did in 17.6% to 30.4%. A £10 deposit already meets the example minimum, so its question becomes doubling, at roughly one chance in five. None of these steps changes the average cost per pound staked, which stays at 4p on a 96% slot whatever the deposit.

Depositing more to improve the odds of a withdrawal is, in plain terms, a decision to gamble more, and the deposit limit set at registration is the place to make it deliberately rather than mid-session. Five pounds is followed game by game on the £5 deposit casino page, and the time a withdrawal takes once requested, from the casino’s approval to the bank, is broken down in the guide to fast withdrawal casinos.

How UK rules shield a £3 session

No rule sets the size of a deposit. Three groups of rules do bear on a small one: those that govern the slot, those that govern any bonus attached, and those that govern the account and the money leaving it.

On the slot: pace, display and stake caps

Since 31 October 2021 no online slot at a licensed site may spin faster than once every 2.5 seconds or offer autoplay, turbo, quick spin or slam stop, or use sounds and images that suggest a win when a spin returns the stake or less; each must also keep total wins or losses and time played on screen during the session. At 20p, a spin that hands back 10p cannot be dressed up as a win, and the 15 spins in £3 take at least 37.5 seconds. The stake limits of £5 a spin for players aged 25 and over (from 9 April 2025) and £2 for 18 to 24 year olds (from 21 May 2025) apply to slots only; 10p and 20p sit far below them, and they do not reach roulette or blackjack. Feature buy-ins, which let a player pay to jump straight to a slot’s bonus round, count as unavailable to British players: on 17 January 2020 the Commission warned operators against offering them, citing one game that charged more than £3,000 to enter its feature, a thousand times this page’s deposit.

On any bonus: the 10x cap and your own money

Since 19 January 2026 wagering at a licensed site cannot exceed ten times the bonus, and no promotion may require two kinds of gambling. On a hypothetical 100% match on £3, the £3 bonus could demand at most £30 of play-through and would be worth £1.80 on the standard formula at 96% RTP, if that play-through were completed. Your own £3 is protected as well. In February 2018 Ladbrokes, William Hill and PT Entertainment committed to the Competition and Markets Authority (CMA) that players can withdraw their own money while playing as part of a bonus promotion, and in March 2018 BGO Entertainment undertook not to make people play their own money through several times before withdrawing it.

On your account: checks, limits and withdrawals

Age and identity are verified before play, a duty since 7 May 2019, and since 31 October 2025 a deposit limit has to be offered before the first payment. The credit-card ban dates from 14 April 2020, crypto is missing from licensed cashiers even though there is no outright ban, and GamStop has covered every licensed online operator since 31 March 2020. Once a withdrawal has been requested, the site may not offer to reverse it or invite you to deposit the same funds again, a ban in force since 31 October 2021. The Commission’s guidance is that a business should not hold on to a customer’s money unnecessarily and should ask for any information it needs at the earliest opportunity, and a complaint has to run its full internal course within eight weeks, after which the business must name an independent ADR (alternative dispute resolution) provider you can escalate to.

Calculator: what your stake costs per session

The calculator turns a stake, a pace, a length of time and an RTP into the average cost of a session. It opens on 20p a spin at an assumed 600 spins an hour for a quarter of an hour on a 96% slot: 150 spins, £30 staked and £1.20 of average cost, which is £4.80 an hour. Set the stake to 0.10 and every money figure halves; set the RTP to 87.25, one of the lower Book of Dead versions, and the cost more than triples. The remaining outputs make the same point from the other side: on average 0.8p is kept from each 20p spin, and £28.80 of the £30 staked comes back. What the calculator cannot show is how long £3 survives that cost, which is what the bankroll tables are for: at 20p, half of all £3 sessions on the model slots were over within 22 to 52 spins.

UK casino brands for a £3 budget: what each type offers

Each brand’s cashier settles whether £3 goes through, method by method, and the answer can change between visits. What differs between brands is the kind of play they are built around and the shape of their offers, and those decide what £3 meets when it arrives. All the brands below hold a Gambling Commission licence, so the slot rules, the 10x wagering cap, verification before play and GamStop apply to every one of them.

Two threads run through the table. First, welcome offers across these groups are built around deposits the operator chooses, and that figure is separate from the cashier minimum, so a £3 deposit may be accepted and still sit outside the welcome. Second, at the casino-first brands slots and tables are the whole offer, so the stake and version decisions on this page are the ones that shape the £3.

Why you usually get one welcome per group

Welcome offers are usually limited to one per person and household, and often to one per group. Entain runs several brands behind one account structure, so a first deposit at Ladbrokes, Coral or Gala Casino can settle what the others will offer you. The same question is worth asking of any two brands with one owner, such as 32Red and Unibet, before treating each as a fresh start.

How to check a brand’s licence in a minute

Licensed brands print the name of their licence holder and their Commission account number in the site footer; Casumo, Midnite, Kwiff, Duelz, Magic Red and Mr Vegas are among those that do. The number can be checked on the Commission’s public register in under a minute, and enforcement action, when it comes, is published against that licence holder rather than the name on the website.

Offshore matches on £3: what clearing them costs

Offshore sites answer the search with bigger numbers. Matches above the 100% to 200% usual at licensed sites, such as 300% or 400%, are typically offshore offers, and wagering of 30x to 60x is common there. None of these sites is licensed in Great Britain, and the bigger numbers do not survive the arithmetic. The casinos in our ranking are offshore as well, with packages that begin at £20 or €20 and wagering of 35x to 40x, so the formula below applies to their bonuses too: price the play-through before deciding a package is worth chasing.

Run a 300% match on a £3 deposit through the standard formula, as an illustration rather than any site’s offer. The bonus is £9. At 40x the play-through is £360, which is 3,600 spins at 10p and two and a half hours even at the 2.5-second pace that offshore sites need not observe. Its value if that play-through were completed, on a 96% slot:

E = B × (1 − W × (1 − RTP)) = £9 × (1 − 40 × 0.04) = −£5.40

Under the UK’s 10x ceiling the same £9 would need £90 of play and be worth £5.40, the same figure with the sign reversed. A negative value is not a debt. It means the average cost of the required play is larger than the bonus, so most sessions run dry before the wagering is met and the few that finish are carried by rare large wins. In the site’s simulation of a larger case, a £10 deposit with a 300% match at 40x played at 20p on Model A, only 9.4% of sessions finished the wagering.

The names behind such marketing recur. Kinghills and NineWin, new arrivals from a family of sister sites registered in Curaçao, with no public record yet, are marketed to UK players through “not on GamStop” pages. Santeda International B.V. runs five Curaçao-licensed brands, Mystake, Goldenbet, Rolletto, Donbet and Velobet, which accept cryptocurrency and are absent from the UK register and GamStop; nothing limits their wagering, and a complaint about them falls outside the Commission’s powers. Rainbet, licensed in Anjouan and operated by RBGAMING N.V., is crypto-first; Roobet and Gamdom are Curaçao crypto casinos that started in the gaming-skins market. None of them is said here to run any particular offer.

For a player on £3 the losses are practical. The 2.5-second minimum and the bans on autoplay and turbo, which stretch 30 spins to at least 75 seconds at a licensed site, are licence conditions an offshore site does not carry. The £5 and £2 stake caps do not apply, GamStop does not reach these sites, and a dispute has no eight-week deadline and no ADR provider at the end of it. A crypto deposit removes any bank protection as well. Offering gambling in Great Britain without a licence is an offence for the operator; the player is not prosecuted, but keeps none of the protections. The homepage guide to spotting fake and offshore offers shows the signs.

How to deposit £3 and make it last, step by step

The order is the one any licensed site follows, with two decisions brought forward to before the deposit, because on £3 they matter more than anything the site does: the stake and the version of the game.

1. Check the licence holder. Read the footer for the company name and Commission account number, then confirm them on the public register.
2. Find both minimums. The cashier shows the minimum deposit for each method; the terms or the payments help page show the minimum withdrawal and whether a full balance below it can be taken out. If either is unclear, ask support in writing before paying in.
3. Choose the stake before the money goes in. At 10p, £3 holds 30 stakes; at 20p, 15. On every model the 10p stake lasted roughly two and a half to three times as long, and the 20p stake was never more likely to reach £10.
4. Choose the version of the game. Open the information screen and read the RTP. At 10p for an hour, the gap between a default and a low version of the same slot can be several pounds, more than the gap between 10p and 20p.
5. Set the deposit limit when prompted. The prompt comes before the first deposit. Size the limit for the whole period, so that a second or third £3 counts against it.
6. Verify, then pay with a method in your name. Identity checks come before any play; pay by debit card or bank transfer, since credit cards and crypto are not accepted at licensed sites.
7. Watch the session figures. Licensed slots show your net position and the time played. When the £3 is gone, the display says so plainly, and that is the natural end of the session.
8. Know your exit in advance. Decide what you will do if the balance touches the minimum withdrawal. Once a withdrawal is requested, the site may not offer to reverse it.

Red flags to spot before a small deposit

Small deposits attract big promises. Any of these signs means the site is not licensed for Britain, the offer is out of date, or the deal is worth less than it looks:

• “Deposit £3, get 300%” or more. Matches of that size are typically offshore, and at 40x the formula value of a 300% match on £3 is −£5.40.
• Wagering above 10x. Since 19 January 2026 no UK-licensed site may ask for more on any bonus.
• Autoplay, turbo or quick-spin buttons. Licensed slots have been barred from offering them since 31 October 2021, along with spins quicker than 2.5 seconds.
• Celebrations for a spin that lost money. A fanfare for 10p back on a 20p stake is banned on licensed slots.
• A “buy the bonus” button. The Commission warned operators against feature buy-ins on 17 January 2020; treat them as unavailable to British players.
• Credit cards or cryptocurrency in the cashier. No UK licensee may take credit cards, and a crypto option strongly suggests the site is not a UK licensee at all.
• “Not on GamStop”. GamStop has been compulsory for licensed online operators since 31 March 2020, so the phrase is an admission that the site is not licensed for Britain.
• A casino bonus that needs a sports bet. Promotions requiring two kinds of gambling have been banned since 19 January 2026.
• An invitation to cancel a pending withdrawal and play on. Licensed sites have been banned from offering it since 31 October 2021, and from inviting you to deposit the withdrawn funds again.
• No licence holder or account number in the footer. Without them there is nothing to check on the register.

£3 against £1, £5 and free spins: which gets you more

The table places £3 among the options either side of it, with every figure taken from the same simulations: the bankroll runs for deposits, the free-spin runs for spins, and the package runs for a deposit with spins attached.

Against a single pound, £3 holds three times the stakes and gave about three times the chance of touching £10; the £1 deposit casino page measures what that smallest deposit buys in each game and how rarely it grows. Against £5 at 10p, £3 is two pounds and about eight to nine percentage points short on Models A to C, and 12.8 points on Model D.

The two bottom rows show what offers change. Thirty free spins on a keep-what-you-win basis are the same £3 of play at 10p with nothing deposited: they returned a median of £1.37 to £2.46 on the four model slots, and the downside of a deposit is simply absent. A £5 deposit with 100 no-wagering spins ended with £10 or more 57.5% of the time in the package simulation, because the spins add £9.60 of average value (100 × 10p × 96%) on top of a deposit that is staked once. A £3 deposit on its own cannot compete with either on value; it can only be the cheaper way of playing with your own money.

Keeping a £3 budget at £3

Setting out with £3 is a sound instinct, and the simulation adds a practical point: the stake is a safety tool as well as a choice of play. Playing 10p rather than 20p does not change the average cost per pound, but it slows the rate at which £3 can disappear, which leaves more room for a considered decision to stop. The budget only works if it holds. A £3 deposit is close to the £3.82 the average slots session cost players in January to March 2026, and topping it up is where a small budget stops being one.

• Set the deposit limit to the budget, not the deposit. Answer the limit prompt with your budget for the whole period, so that a second and third £3 count against it.
• Keep the stake at the bottom of your range. The legal caps of £5 a spin, or £2 for 18 to 24 year olds, are ceilings, not targets.
• Fix both stopping points before the first spin. One is a loss point, which on a £3 budget is simply the moment the £3 is gone. The other is a win point, such as the minimum withdrawal. The simulation’s figures for touching £10 describe players who stop the moment they get there; a session that carries on can hand it back.
• Read the net position before any top-up. Licensed slots must display wins or losses and time played for the session.
• Take a time-out if a session has run past the point you planned; it locks the account for a set period.
• Self-exclude through GamStop if gambling has stopped being a choice; one registration covers every licensed online site.
• Call the National Gambling Helpline on 0808 8020 133 to talk to someone about your own gambling or a person close to you.

How we worked out the numbers

Every slot figure on this page was produced by repeated random play (a Monte Carlo method, written in numpy with fixed seeds) on four model slots. Their settings: medium volatility, 96% RTP, a bonus round every 170 spins on average and a 2,500x ceiling for Model A; high, 96.21%, every 200 and 5,000x for Model B; medium-high, 96.71%, every 180 and 2,100x for Model C; low, 96%, every 120 and 200x for Model D. The bankroll rows used 40,000 sessions for every combination of model, starting balance and stake, each held at one stake until the balance could not pay for a spin or the 1,440th spin was reached; a session counts as having touched £10, or doubled, if its balance got there at any point before it ran out. The per-pound increments, spins per stake and spins per pound are arithmetic on those published rows. The free-spin figures used 400,000 sessions per row and the deposit-and-spins package 100,000.

The cost-per-hour table is arithmetic: stake × spins × (1 − RTP), using the providers’ published versions and an assumed 600 spins an hour. The roulette chances follow exactly from the single-zero layout, with no simulation involved. Bingo figures rest on simulated 90-ball games using randomly built tickets, at illustrative paybacks of 70% to 90%, and the five-game figure applies the simulated chance per game five times over. The offshore example uses the standard formula, value = bonus × (1 − wagering × house edge), as a yardstick, not a forecast. Official statistics are the Gambling Commission’s for the period stated.

The limits are real. A model slot is a stand-in, since providers do not publish pay tables. Sessions never changed stake, so anyone who varies the stake or quits while in profit will see different outcomes. The one-hour cap trims the longest-lasting sessions, which mainly affects Model D at larger balances.
