Keep What You Win on 30 Free Spins: What the Promise Is Worth and How to Check It

Keeping what you win: the short version

• The promise is about the winnings, not the spins. A genuine offer credits whatever the thirty spins pay to your withdrawable balance with no turnover attached. At 10p a spin that is £2.88 on average, and our runs put the middle result at £1.79 with 77.4% of claims keeping at least £1.
• One sentence decides it, and it is in the spins clause. Look for the winnings being credited as cash with no wagering. The words that give a lookalike away are bonus funds, playthrough, turnover and conversion, and any of them moves the offer down two rows in the table below.
• A ten-times line costs far more than the formula admits. On paper it leaves £1.76 of £2.88. In 100,000 simulated sessions only 12.9% reached the end of the requirement, so the middle result fell from £1.79 to nothing at all.
• A ceiling is usually a detail, and a low one is not. A £60 ceiling took 7p off the average in our runs and a £12 ceiling took 34p, while neither moved the middle result by a penny. Below about £10 the line starts cutting into ordinary good nights.
• Above ten times, the site is not licensed here. British licensees have been held to that ceiling since 19 January 2026. A paid offshore package asks 35 to 40 times on a first payment of £20 or €20 under licences from Anjouan, Curaçao and Costa Rica, which means no Gamstop, no British wagering limit and no British complaints route.

One rule to keep: if the terms do not say the money is cash, assume it is not, and price the offer at the lower figure before you decide.

The four lines that make the promise true

Everything that matters can be read before you give anybody your details. Do it in this order, because the first line settles more than the other three together.

1. Find the spins clause and read what happens to the winnings. You are looking for a sentence putting them into the cash or withdrawable balance with no requirement. If it says the winnings become bonus funds, the three words in the headline are describing what happens after a play-through, which is a different offer worth about 60% as much on paper and far less in practice.
2. Read the line about a maximum. Keep what you win, up to a number, is still a genuine offer with its top sliced off, and on a batch this size that top is rarely reached. Our runs say a £60 ceiling costs 7p of a £2.87 average and a £12 ceiling 34p. Treat anything above £20 as a detail and anything under £10 as a real reduction.
3. Find the smallest withdrawal the cashier will send. This is the line that strands more kept winnings than any other. If the minimum is £10, only 2.3% of our simulated claims reached it from the spins alone, so the money is yours and sitting still. That is fine, as long as you know it before you start rather than after.
4. Check that nothing else has to happen first. A requirement to deposit before a first withdrawal turns the offer into the opening step of a deposit deal, which you should then value on its own terms. An expiry does the same job more quietly: spins usually lapse between a day and a week from crediting, and the thirty spins themselves take a minute and a quarter to play.
5. Only then look at the licence and the count. The company named at the foot of the site and its Commission account number can be checked on the public register in a minute, and that licence is what brings the ten-times ceiling, Gamstop cover and an eight-week deadline on complaints. The spin count, the number in the headline, is the last thing to compare, because five spins either way is worth 48p.

Four lines, perhaps sixty seconds of reading, and the difference between them is worth more than a pound on an offer whose whole face value is £3. That ratio is the reason this page exists.

What thirty kept spins actually put in your balance

The arithmetic first, since it is the part that travels. Thirty spins at 10p put £3 through the reels, and the average coming back is that stake multiplied by the game’s return.

30 × £0.10 × 96.1% = £2.88

Where the winnings are cash, that £2.88 is also what the offer is worth to you, with nothing to subtract. It is the number to use when you set this offer beside any other. What it does not tell you is what your own evening looks like, and thirty spins is a short evening.

So we ran 250,000 claims of thirty 10p spins on our House model slot, a medium-volatility model returning 96.1% with a win on 26.94% of spins, a feature about every 145 spins and a top prize of 2,500 times the stake. The simulated average came out at £2.87, a penny under the arithmetic, which is the check that the model behaves.

Two readings fall out of that. The first is that the average is not the plan: £2.87 sits above three quarters of all claims, because a thin band of big results carries it. Budget for the middle column instead, which means a pound or two, and treat £3 as a good night rather than the usual one. The second is how reliable the small win is. Not a single claim in 250,000 came back with literally nothing, 77.4% kept at least £1 and 11.1% reached £5, which is what thirty spins on a game paying out better than one spin in four buys you.

Where it stops being generous is the top. Only 2.3% of claims reached £10 and 1.3% reached £20, so a kept win is almost always small change rather than a withdrawal. That is not a criticism of the offer; it is the shape of every thirty-spin batch ever advertised, and a page that implies otherwise is selling you something.

The game sets the typical night, not the average

Two welcomes can carry the same three words, the same count and the same stake and still produce different evenings, because the game underneath is doing the work. We put the same thirty spins through two more of our model slots: the Easy model, low volatility at 96.4% with a win on 39.2% of spins and a top prize of 250 times the stake, and the Wild model, high volatility at 95.8% with a win on 15.0% of spins and a ceiling of 12,000 times.

The averages are within 3p of each other and the middle results are 92p apart. On the calm game nine claims in ten kept at least a pound and the typical player finished on £2.34; on the volatile one almost four claims in ten finished under a pound and the typical player on £1.42. What the volatile game gives back is the chance of something worth withdrawing, 3.9% reaching £10 against 1.5%.

So the honest advice depends on what you want from £3 of free play. If you want a small, near-certain win to keep, pick the calm game; the feature turns up on 27.2% of thirty-spin claims there against 10.9% on the spiky one, and that is where the steadiness comes from. If you would rather have a thin shot at a balance you can actually withdraw, the volatile game is the rational choice, and you should still expect to miss. Matching a spin offer to the game it runs on takes that trade across every batch size.

Six wordings, and what each one is really offering

Here are the six versions of this promise you are most likely to meet, priced on the House model runs above. The middle column is what the typical claimant walks away with, which is the column the adverts never show.

Rows one to four all hand the middle claimant the same £1.79, because the ceiling and the cashier floor only touch results that are rarer than the typical one. Rows five and six send the money back round the reels, and that is where the typical result collapses to nothing. If you take one thing from this page, take the gap between row one and row five: the same headline, the same thirty spins, and the difference between keeping £1.79 and keeping nothing at all.

The vocabulary is consistent enough to use as a filter. Cash balance, withdrawable balance and no wagering put an offer in the first row. Maximum win, maximum cash-out and up to £ put it in the second or third. Bonus funds, bonus balance, playthrough, turnover and converted to cash put it in the fifth. A deposit required before your first withdrawal is its own category, because it quietly makes the offer part of a deposit deal rather than a free one.

When the keeping happens after a play-through

This is the common lookalike at a British-licensed casino, because up to ten times is allowed here. The formula gives its paper value: multiply the winnings by one minus the multiple times the house edge, which on a 96.1% game is 3.9p in every pound.

£2.88 × (1 − 10 × 0.039) = £1.76, and at thirty-five times, −£1.05

The paper value assumes you finish. To find out how many people do, we took the same thirty-spin claims and staked whatever they won at one flat stake until either the target was reached or the balance could not cover another spin.

Three things in that table are worth saying out loud. The averages barely fall, from £2.87 to £2.33 and £2.01, which is why an operator can describe a wagered offer in warm language without lying. The middle result falls off a cliff, from £1.79 to nothing, because 87.1% of sessions ran out of money before the target. And the one honest argument for the wagered version sits in the final column: forced play pushed 5.4% of sessions to £10 or more, against 2.3% when the winnings were simply kept, so the requirement trades an almost certain small win for a slightly better shot at a withdrawable one.

Stake size does not rescue it. At 20p a spin the target arrives in half as many spins, and fewer sessions survive to reach it, 9.7% against 12.9%, because a balance of £2.88 absorbs fewer big bets than small ones. The requirement itself is modest in time: ten times £2.88 is £28.80 of stakes, 288 spins at 10p, about twelve minutes at the legal pace. Time was never the price.

10 × £2.88 = £28.80 of stakes, or 288 spins at 10p

One more line from the arithmetic, since it explains why offshore versions of this offer are hopeless. On a 96.1% game the formula value runs out just past twenty-five times, where the expected cost of the play-through catches up with the winnings being played through. Anything beyond that is negative before a reel turns, which is where the next two sections start.

Keep what you win, up to £60

The commonest qualification on a genuine offer is a maximum, usually somewhere between £20 and £100 and occasionally lower. It does not make the promise false. It removes the top of a distribution that most claimants never reach, and the only question worth asking is how far up it sits.

We re-scored the same 250,000 claims under two ceilings. A £60 maximum left an average of £2.80, taking 7p, and touched 0.3% of claims. A £12 maximum left £2.53, taking 34p, and touched 1.6%. Neither moved the middle result from £1.79 by so much as a penny, because the typical claim is nowhere near either line.

£2.87 − £2.80 = 7p at £60; £2.87 − £2.53 = 34p at £12

So the rule of thumb is simple. A ceiling at £20 or above is a detail you can ignore on thirty spins. A ceiling in single figures is a real reduction, and on a high-volatility game it is a larger one, because that is where the value is stored. What a ceiling never does is change what you are likely to walk away with.

The cashier minimum is the more annoying limit, and it applies to kept cash as much as to anything else. At a £10 floor, 2.3% of our claims could withdraw from the spins alone, which leaves 97.7% holding money that is genuinely theirs and genuinely stuck. The good news is that kept cash behaves differently from bonus funds: it does not expire with a promotion, it sits in the balance under the account terms, and it can leave later alongside other money. Bonus funds usually lapse within a few days to a month, taking anything unconverted with them.

If a licensed operator will not pay out something you believe you are owed, the licence is what gives you somewhere to go. The business has eight weeks to finish handling a complaint, escalation inside the company included, and must then tell you how to reach an independent dispute resolution service. The Competition and Markets Authority’s investigation into online gambling, opened in 2016, produced undertakings in 2018 that withdrawal minimums would not be used to stop players taking out a whole balance, and the Commission told operators in August that year to remove withdrawal restrictions that were unfair.

When an offshore welcome says its spins carry no requirement

At the October 2026 check, one set of offshore terms out there stated that the winnings from its free spins arrive with no wagering attached. If the terms you are reading still say that, then those spins are this page’s promise in its paid form, and the comparison is worth making carefully.

What would be the same: the winnings land as money rather than as something to turn over, so a batch of thirty spins at 10p on a 96% game would be worth about £2.88 on average and would leave the typical claimant a pound or two, exactly as the runs above show. What would be different is everything around it. The spins arrive after a payment of at least £20 or €20 rather than for nothing. The match money that comes with them keeps the package’s own wagering, which out there runs from 35 to 40 times. Identity documents are wanted before a first withdrawal. And the licence named in the terms is issued in Anjouan, in Curaçao or in Costa Rica, none of which brings Gamstop cover, the British ten-times ceiling or a British complaints route.

That last point is worth a worked illustration rather than an assertion, and this is an illustration, not the terms of a particular offer. Take a first payment of £20 matched at 200%, which gives £40 of bonus money, and apply a requirement of 40 times to the bonus alone.

£40 × 40 = £1,600 to stake; £40 × (1 − 40 × 0.04) = −£24.00

The spin half of a package and the match half behave completely differently, in other words, and an offer paying spin winnings as money is telling you something real about one half while the other half carries the number that decides the package. Read both lines, and remember that terms change: treat what is written here as a description of one check on one day rather than a standing fact about anybody. The deposit offers section compares the packages properly on minimum deposit, wagering and spin terms.

The honest summary for most readers is that the two things are not competing. A free batch of thirty kept spins costs nothing and returns a pound or two. A deposit package is a purchase, to be judged with money you had already decided to risk, and never a way to turn £1.79 into something bigger.

Offshore free chips wearing the same three words

Outside the British system the phrase usually sits on a free chip, a lump of bonus money rather than a batch of spins, with wagering of thirty to sixty times and a cash-out limited to £100 or less. The headline numbers are far bigger than anything a licensed site offers, and they have to be, because the terms take them back.

We priced one. A £30 chip at 50 times, staked at 25p a spin on our House model with a £100 ceiling applied at the end, needs £1,500 of stakes, which is 6,000 spins. Across 50,000 simulated sessions, 7.2% reached the end of it, 92.8% finished with nothing, and the average kept was £6.28, almost all of it belonging to the 6.3% who got past £50. The formula value before the ceiling is minus £28.50. Soften the requirement to 30 times and the same chip needs £900 of stakes, 3,600 spins, with 10.7% finishing, 89.3% left empty, an average of £8.82 and a formula value of minus £5.10.

Set that beside the licensed offer this page prices. Thirty kept spins take a minute and a quarter, return £2.87 on average and leave the typical player £1.79. A £30 chip at 50 times takes 6,000 spins, returns more on average and leaves the typical player nothing whatever. Averages are not the same thing as outcomes, and a chip is the clearest illustration of the difference in this whole corner of the market.

What is missing matters more than the maths. A self-exclusion registered through Gamstop does not reach these sites. The ten-times ceiling does not bind them, the stake limits of £5 a spin from the age of 25 and £2 below it do not apply, nobody prompts a deposit limit, no British body will hear a complaint, and a payment made in coin has no bank able to pull it back. Serving customers in Great Britain without a Commission licence is an offence, and the operator is the one who answers for it.

The names you will meet are worth knowing. Donbet, Velobet, Mystake, Rolletto and Goldenbet all belong to one Curaçao company, Santeda International B.V., so five shopfronts mean one counterparty; the five take coins, cap nothing, sit outside the British register and Gamstop, and are beyond the Commission’s reach if something goes wrong. NineWin and Kinghills are newer Curaçao arrivals running networks of sister sites with no public record behind them. Rainbet is licensed in Anjouan, in the Comoros, through RBGAMING N.V., and built around coin deposits. Gamdom and Roobet, also Curaçao, came out of the trade in in-game skins. The section on casinos outside GamStop covers what each of those licences does and does not carry.

Which British brands pay bonus winnings as cash

No brand is named here as running an offer this week, because these promotions change constantly and only each operator’s own promotions page is current. What is stable is policy, and on this particular question two brands have one.

MrQ, from Lindar Media, and PlayOJO, from SkillOnNet, do not attach wagering to any bonus. Whatever a spin wins at either is cash from the moment it lands, which makes the first row of the table above their default rather than a special offer. The trade is that their batches are usually modest in size, and on the figures here that trade is a good one: a cash batch of nineteen spins on a 96.1% game is worth £1.83, which already beats thirty spins carrying a ten-times line at £1.76.

Elsewhere you have to read, and the shape of the business tells you what to expect. The casino-led brand inside a large group is the likelier home of a batch that needs no payment: Sky Vegas within Flutter Entertainment, where Sky Bet, Betfair and Paddy Power start their casino welcomes from a deposit or a stake; 32Red within Kindred, beside the sportsbook-led Unibet; and 888 Casino within evoke, online since 1997 and an advertiser of no-deposit spins for a decade, with 777 Casino nearby and William Hill in the group since 2022. Betway runs sport and casino under one name with deposit-based welcomes, and bet365, whose licence also carries Heart Bingo, treats its casino as the second half of a betting business.

Group structure then limits how many of these you can take. Ladbrokes, Coral, Gala Casino, Gala Bingo, Foxy Bingo and PartyCasino share Entain’s account system and normally share a single welcome, so claiming at one can close the door at the rest. The same caution applies wherever a platform is shared: Jackpotjoy, Virgin Games, Monopoly Casino, Rainbow Riches Casino and Double Bubble Bingo all sit on Gamesys Operations Limited, Gambling Commission account 38905, where the usual welcome asks for £10 and gives you more to play with and the small extras arrive once you are a customer. Pink Casino runs on LeoVegas Gaming PLC, account 39198, in the mobile-first group that also carries Bet UK and BetMGM, whose British site has used the LeoVegas licence and platform since 2023.

One format is easy to mistake for this offer. Where a welcome is a single turn of a prize wheel after a first deposit, as at Amazon Slots on Jumpman Gaming’s account 39175, the spin count in the headline is the best segment on the wheel rather than the usual result, and you have paid in before you spin it. That is not keep what you win; it is a prize draw with a deposit attached.

For anyone who wants a business with a door, Admiral Casino, Genting Casino, Grosvenor Casinos and Betfred all run premises here, and Rank Interactive (Gibraltar) Limited holds Grosvenor Casinos and Magical Vegas on account 57924. For the rest, from All British Casino, Voodoo Dreams and Dream Vegas to Casumo, Videoslots, Mr Vegas, Midnite, Kwiff, NetBet and Duelz, the footer names the licensed company and its account number and the public register does the rest in a minute. Enforcement is published against that company rather than the brand, and the two largest figures on the records above are £19.2m for William Hill in 2023 and £17m for Entain in 2022, with Betway at £11.6m in 2020 and bet365 at £582,120 in 2024.

Price the offer and the chip

The first calculator opens on the lookalike rather than the real thing, because that is the case worth checking: thirty spins at 10p on a 96.1% game, winnings carrying ten times, with a £60 maximum. Set the wagering box to zero and you have the genuine version, and the value jumps from £1.76 to £2.88.

Three more things to try. Change the spin value to 0.20 and every figure doubles, which is why the stake matters more than the count. Set the maximum to 12 and watch how little the average moves. And set the wagering to 35 to see the figure turn negative, which is the formula’s way of saying the play-through is expected to cost more than the spins win.

The second calculator prices a free chip instead, which is a different shape of offer because the whole sum is staked rather than won first. It opens on the offshore case from the section above, £30 at 50 times on a 96.1% game with a £100 ceiling.

Neither tool can tell you how many people finish, which is the number that decides whether a requirement is worth attempting at all. For that, the simulated columns are the guide: 12.9% at ten times on the spins, 7.2% on the chip. For offers either side of this one, the twenty-five-spin registration guide works through the terms that separate two similar offers, the fifty no-wager spins guide takes the same promise to the top of the no-deposit range and the £5 no-deposit guide prices a small cash bonus, which behaves like a miniature chip.

A kept win is the easiest money to give back

The moment £1.79 lands in a cash balance it belongs to you, and from that moment every pound you stake again on a 96.1% game returns about 96p on average. Playing on is therefore the single most reliable way to make a kept win smaller, and the fact that it was free to begin with makes it easier to do.

Set the stopping point before the first spin, in words you will recognise later: whatever the thirty spins pay, that is the evening. If the balance sits below the cashier minimum, leave it there rather than playing it up, since most attempts to reach a £10 floor end at zero instead. A deposit limit chosen at sign-up costs nothing on an offer that needs no deposit and is already in place if you ever do pay in, and British slot rules add a floor of their own: no spin faster than two and a half seconds, no autoplay, and a ceiling of £5 a stake from the age of 25 and £2 between 18 and 24.

If claiming has stopped feeling like an occasional errand, the tools are free and they work together. One registration with Gamstop shuts every online operator licensed here in a single step, GamBan blocks gambling sites on the devices you own, and a block set with your bank closes the payment route. GamCare runs the National Gambling Helpline on 0808 8020 133, free and confidential at any hour, and it is there for anyone worried about someone else as well.

One closing comparison, since this is a bingo site. Keeping what you win is a promise a slot offer can make precisely because a slot publishes a return you can look up. A bingo room publishes nothing of the kind: the Commission’s technical standards let a bingo game set out how it shares prizes instead of quoting a return, and the one sector-wide figure worth having is that remote bingo handed back 83.25% of ticket money as prizes in 2025-26, down from 91.67% a decade earlier. The free bingo guide values a free ticket by the size of the room instead, which is a different and rather more sociable kind of arithmetic.

Where these figures come from

Three model slots carry the simulations, and none of them is a real game. The House model, which produces every figure not otherwise attributed, is medium volatility at a 96.1% return, pays on 26.94% of spins, finds its feature about every 145 spins and tops out at 2,500 times the stake. The Easy model is low volatility at 96.4%, paying on 39.2% of spins, with a feature about every 95 and a maximum of 250 times. The Wild model is high volatility at 95.8%, paying on 15.0% of spins, with a feature about every 260 and a maximum of 12,000 times.

Kept winnings come from 250,000 simulated claims of thirty spins at 10p on each model, and the £60 and £12 ceilings were applied afterwards to those same claims so that nothing else changed. The wagered rows are 100,000 sessions apiece at ten times and 50,000 at thirty-five times: the thirty spins are played, then the winnings go back at a flat 10p or 20p a spin until the target has been staked or the balance will not cover another spin, with a session that runs dry counting as nothing. The free chip is 50,000 sessions of a £30 bonus staked at 25p a spin on the House model, with the £100 ceiling applied at the very end. The chance of finding a feature in thirty spins is calculated from each model’s own frequency rather than simulated.

Two pieces of arithmetic run through the page. Average spin winnings are the count times the stake times the return, which is where £2.88 comes from. The value of a finished requirement is the winnings multiplied by one minus the multiple times the house edge, the house edge being whatever the game does not return; it describes the people who complete the play-through rather than the ones who go broke part-way, which is why the simulated columns sit beside it everywhere.

The rules behind the page belong to the Gambling Commission. The ten-times limit on bonus wagering and the end of promotions spanning more than one product type both took effect on 19 January 2026. Stake ceilings on online slots arrived on 9 April 2025 for players aged 25 and over and on 21 May 2025 for those aged 18 to 24. Operators have had to prompt a deposit limit before a first payment since 31 October 2025, to verify age and identity before any play since 7 May 2019, to belong to Gamstop since 31 March 2020 and to refuse credit cards since 14 April 2020, and the design rules that removed autoplay and set the two-and-a-half-second floor came into force on 31 October 2021. The eight-week complaints deadline and the independent dispute route are also the Commission’s; the 2018 undertakings on withdrawal limits come from the Competition and Markets Authority case file; the bingo payback figures are the Commission’s industry statistics. Where this page says “usually” about spin counts, ceilings, expiry windows or offshore wagering, it is describing a range rather than a rule, with the thirty-to-sixty-times band and the £100 cash-out limit taken from Gambling Insider’s 2026 guide. Brand facts come from our own brand sheet and never imply a live offer, and the offer descriptions reflect one check in October 2026.
