100 Free Spins No Deposit UK: Best Offers Compared on Deposit, Batches and Wagering (October 2026)

Quick answer: comparing 100-spin offers before you deposit

• Expect a deposit, and compare it. UK-licensed casinos usually tie 100 spins to a first deposit of £10 to £20, while the ranked packages start at £20 or €20 and spread 150 to 500 spins over several deposits. The deposit stays your own money, so judge each offer on what its spins add.
• Read the wagering before the spin count. At 10p, 100 spins are worth £9.60 as cash, £5.76 by the formula at 10x and −£3.84 at 35x. The ranking’s cards show 35x to 40x, and 93.7% of simulated 35x sessions at 10p stakes ended with nothing.
• Count the batches you will really collect. On a 10-a-day schedule each missed day costs 10 spins, 96p before wagering; at 20 a day it costs £1.92.
• Check the spin value. The same 100 spins average £4.80 at 5p and £19.20 at 20p, so a smaller count at a higher value can beat a bigger headline.
• Prefer wagering per batch, and watch for low caps. Ten batches each with their own 10x left 44.4% of simulated players with something, against 16.0% under one requirement on all 100 spins; a £20 cap on converted winnings holds the 10x average to £3.20 at most.

No-deposit spins at casinos licensed by the Gambling Commission usually come in counts of 5 to 20, occasionally up to 50, so a 100-spin offer that needs no payment is a rare find. Once an offer reaches 100 spins or more it usually needs a deposit, and the spins are often credited in daily batches rather than all at once.

In practice the UK version of the headline is built from three parts:

• A qualifying deposit. Usually £10 to £20 by debit card, made after your identity has been checked and after you have been prompted to set a deposit limit.
• A release schedule. The spins land on one named slot, normally at 10p each, often 10 or 20 a day, and each day’s batch can expire if it is not used.
• A payout rule. The winnings are either cash, with no wagering, or bonus funds that must be staked up to 10 times before they can be withdrawn.

Two rule changes on 19 January 2026 shaped what is left. Wagering on any bonus may not exceed 10 times the bonus, and promotions that mix gambling products are banned, the Commission’s own example being betting combined with slots, so a spin package can no longer hinge on a sports bet. Before that date nothing stopped a licensed casino from attaching 35x to the same spins, and the simulation further down shows what that meant for the people who claimed them.

The “no deposit” half of the search mostly leads offshore. Sites licensed in places such as Curaçao or Anjouan advertise large no-deposit spin counts and bonus “chips”, attach wagering of 30x to 60x and usually cap what a no-deposit bonus can pay out at £100 or less. None of GamStop, the 10x cap or a UK complaints service reaches them. The casinos in our ranking are licensed offshore as well, but what they offer is deposit packages, not no-deposit chips. If what you want is spins without paying anything in, the realistic licensed options are smaller, and the guide to 50 free spins with no wager covers the top of that range.

What to compare on each 100-spin package

A UK 100-spin offer and a package from the ranking can be set side by side on the same handful of lines, even though the ranked packages carry more spins and ask for more money. The table names each line, where to read it and what it is worth on 100 spins at 10p, using the formula and the Model A simulation from the sections that follow.

The deposit row looks like the biggest difference, but the wagering row is where the value moves. Between the UK’s 10x and the 35x at the bottom of the ranking’s range, the formula value of 100 spins at 10p swings by £9.60, the whole average the spins pay, and the simulated finish rate falls from 16.0% to 6.3%. A bigger package at a higher multiple can therefore be worth less than a smaller one at 10x, so read the wagering line before the spin total.

What 100 free spins pay at 5p, 10p and 20p

Each free spin is a wager made on your behalf: the casino fixes the stake and picks the game. What the spins are worth begins with two numbers, the total staked and the slot’s return to player (RTP), meaning the percentage of everything staked that the game hands back over millions of spins. At 10p, 100 spins are £10 of stakes, and a 96% slot returns £9.60 of that on average. If the winnings arrive as bonus funds, the wagering takes its share, and the site uses one formula for that throughout:

E = B × (1 − W × (1 − RTP))

B stands for what the spins win on average and W for the wagering multiple. For 10p spins at 10x, the play-through is 10 × £9.60 = £96, its expected cost at 4p per pound staked is £3.84, and the expected cash is £9.60 − £3.84 = £5.76. The table repeats the sum for the three spin values UK offers use.

A useful way to read the 10x column: by the formula, 100 spins at 10x and 60 spins with no wagering come out identical, at £5.76. A 10x requirement costs the equivalent of 40 of the 100 spins. At 35x the formula value turns negative, because £336 of play-through costs £13.44 on average, more than the spins pay. That does not mean anyone loses money on free spins: a bonus balance that hits zero simply ends, so no result can be negative. It means the play-through costs more than the spins win, and the next two sections show how that plays out in practice.

Two details change the sums for a real offer. First, the requirement is set on what you actually win, not on the average: a player whose spins paid £20 faces £200 of play-through at 10x, and one whose spins paid £3 faces £30. Second, under wagering the slot’s RTP counts twice. If the named game runs a 94% version, the spins’ average falls only from £9.60 to £9.40, but if the play-through is on the same game, every pound of it now costs 6p instead of 4p, and the 10x value falls from £5.76 to £3.76, a third lower. Check the RTP in the game’s information screen before you decide how good the offer is.

What 100 spins really pay: 400,000 simulated sessions

The £9.60 average hides a wide spread, so the simulation ran 100 spins at 10p 400,000 times on Model A, a 96% RTP model slot of medium volatility. On Model A, 27.9% of spins land a win of some kind, and about one spin in 170 triggers a bonus round paying from 8 to 2,500 times the stake. It illustrates a generic medium-volatility slot rather than copying any real game, since real pay tables are not published.

Put another way, out of every 100 sessions roughly 24 ended between £2 and £5, 53 between £5 and £10, 18 between £10 and £20, 4 between £20 and £50 and 1 above £50. For one player, that means a session of 100 spins almost never ends empty-handed, the most common outcome is somewhere between £5 and £10, only about one player in four reaches £10, and one in twenty reaches £20.

Why most players collect less than the £9.60 average

On Model A the bonus round supplies about 36p of every 96p returned; line wins in the base game supply the other 60p or so. In 100 spins, 55.4% of sessions never trigger a bonus round, and those sessions live on line wins worth about £6 on average. The sessions that do trigger one, and especially the rare large ones, lift the average to £9.57 while the median stays at £6.90. The slot’s character changes the gap. On Model D, a low-volatility model with a bonus round about once in 120 spins and a 200x maximum, the median for 100 spins is £8.92 and the 99th percentile £23.18, against £6.90 and £84.30 on Model A: a steadier typical result, with the big outcomes gone.

What a win cap costs a 100-spin package

No-deposit spin offers often cap what the spins can pay, typically somewhere between £20 and £100, and capped deposit packages work the same way. What a cap costs depends entirely on how many sessions climb past it:

At 100 spins the common caps cost little until they get small. A £20 cap affects one session in twenty and takes £1.47 from the average; a £10 cap affects nearly one in four and takes £2.53; a £5 cap touches three sessions in four and halves the offer. Caps on wagered winnings, which limit how much bonus money can be converted to cash, were not part of the simulation, but simple arithmetic bounds them. As the next section shows, only 16% of sessions finish 10x at 10p stakes, so a £20 conversion cap would hold the average after wagering to at most £3.20 (16% × £20), less than half the uncapped £7.56.

How much of 100 spins survives 10x or 35x wagering

For the wagering runs, a separate set of 100,000 sessions played 100 spins at 10p (their winnings averaged £9.60) and treated whatever each one won as bonus funds. Every session then kept betting that balance on Model A, one fixed stake per spin, until it had staked 10 or 35 times its own winnings or was left with less than one stake. Being left short meant losing the lot, as a bonus balance would at a casino. The play-through was run once at 10p a spin and once at 50p.

The table separates two ideas that the formula merges into one. After 10x at 10p stakes, the average cash is £7.56, above the formula’s £5.76 and not far below the £9.57 the spins paid. The median is £0.00. Both figures are correct, and the finish rate explains how they fit together:

1. The requirement dwarfs the balance. Half of all sessions start the wagering with £6.90 or less. At 10x that is £69 to stake, 690 spins at 10p, from a balance that covers 69 of them.
2. Most spins pay nothing. On Model A, 72.1% of spins return nothing at all, so a small balance drains steadily between wins, and one long dry run is enough to end the session.
3. Running out is final. Once the balance cannot cover a stake the session is over, however close it was to the target. The formula has no such floor; real play does.
4. More than half run out, so the middle result is zero. At 10x and 10p, 84 sessions in 100 ran out. Line all 100 up from lowest to highest and the 50th is zero, and so are the 30th and the 80th.
5. The few who finish carry the average. The 16% who finished ended with about £47 each on average (£7.56 ÷ 16.0%), and that alone holds the overall average at £7.56.

The same mechanism explains why the simulated average sits above the formula. A session that busts early never stakes the remainder of its £96, so it never pays the 4% edge on that remainder; the formula, by contrast, bills every player the full £3.84. Neither number is wrong. The formula is the right yardstick for comparing one offer with another; the finish rate and the median describe what usually happens to the person who claims it.

Which stake gives the better chance: 10p or 50p

Raising the stake to 50p meets the requirement in a fifth of the spins but makes each swing five times larger. The finish rate fell from 16.0% to 9.0%, the finishers’ average rose to about £88, and the overall average edged up to £7.89, because shorter sessions pay the edge on less money. The median stayed at zero. In plain terms, low stakes give more players a modest chance and higher stakes give fewer players a bigger result, and neither changes what happens to most of them.

35x and above: what offshore-level wagering leaves of 100 spins

Before 19 January 2026 a licensed casino could attach 35x to the same spins, and offshore sites still do; the ranking’s cards show 35x to 40x, so this is the row to set beside them wherever a package’s multiple covers its spin winnings. The formula value is −£3.84: staking £336 on a 96% slot costs £13.44 on average, more than the spins win. In the simulation, 93.7% of sessions ran out at 10p stakes and 6.3% finished, and those finishers averaged about £104, enough to keep the overall average at £6.56. So the honest summary of a 35x offer is that about 94 players in 100 ended with nothing and roughly 6 large results carried the average. The cap raised the share of 10p sessions that finish from 6.3% to 16.0%, and that is the real change the rule made for someone claiming 100 spins.

Daily batches: what a missed day costs and how wagering is split

A 100-spin package is often paid out over several days, which raises two questions the headline never answers: what a missed day costs, and whether each day’s winnings carry their own requirement or join one pot.

The first is plain arithmetic. If each batch expires 24 hours after it lands, a missed day is lost, not postponed. On a 10-a-day schedule each missed day removes 10 spins, worth 96p on average before wagering and 58p by the formula after 10x (75p on the simulated average). On a 20-a-day schedule a missed day removes £1.92 before wagering and £1.15 by the formula after it (£1.55 simulated).

The second question changes the odds far more than the value. The simulation’s 10-spin and 20-spin wagering runs let each batch be treated as its own session with its own 10x requirement, played at 10p, and set against one requirement on all 100 spins’ winnings:

The formula value is identical and the averages sit within 25p of each other, but the chance of ending with something rises from about one in six to more than two in five when each of ten batches is wagered on its own. The amounts are smaller: a 10-spin batch starts with about 96p, and the sessions that finish its requirement end with about £13 on average (£0.75 ÷ 5.7%). The terms tell you which row you are in; look for wording such as “winnings from each batch” or “winnings from all free spins”. The batch rows treat each batch as an independent session, which is how the underlying runs were simulated, and multiply out the chance that every one of them runs dry.

How long 100 spins take to clear, and the £10 minimum withdrawal

Since 31 October 2021, online slots in Great Britain have had to take at least 2.5 seconds a spin, and autoplay has been banned. The 100 free spins alone take 4 minutes 10 seconds at that pace, spread over several visits if they come in batches. Clearing a requirement on £9.60 of winnings takes much longer at the stakes most players use:

These are floors, not estimates: real sessions include pauses, loading screens and decisions. The quicker routes also come with lower finish rates, as the 50p rows above showed. The law also sets a ceiling on speed, £5 a spin from age 25 and £2 below it, and a bonus’s maximum-bet rule may set a lower one.

The minimum withdrawal matters at both ends of the offer. With no wagering, 23.1% of simulated 100-spin sessions reached £10 from the spins alone, so a £10 minimum leaves about three players in four holding cash they cannot yet withdraw. With 10x wagering at 10p stakes, 11.8% ended with £10 or more, and only 4.2% of all sessions finished the requirement with less than £10. Wagering has already removed most of the small balances, so the minimum gets in the way for only about a quarter of the few who finish.

Value any 100-spin package with the calculator

The tool below starts from the usual UK shape of this offer: 100 spins at 10p, 10x wagering on the winnings, a 96% slot and no cap. Enter the offer’s own figures: the number of spins you expect to use (not the headline, if you know you will miss batches), the spin value, the wagering multiple (0 if the winnings are paid as cash), the RTP from the slot’s information screen and any maximum win. The result is the value if the wagering is played through in full, the yardstick for comparing offers, together with how long the requirement takes to clear at 10p and at £1 a spin.

Keep in mind what it leaves out. On Model A at 10p stakes only 16% of sessions finished 10x, so read the result as the offer’s value on paper, not as what most players take home.

UK-licensed brands and how they build deposit spin packages

Because 100 spins usually need a deposit, the useful question is not which brand gives them away but how each group builds its welcome around a first payment. Offers change often, so what follows describes each group’s general approach rather than anything live on a given day. All of these brands hold Gambling Commission licences, which means the 10x cap, verification before play, GamStop participation and no credit cards; none of them offers cryptocurrency either.

Deposit-led casino and bingo brands: spins after a first payment

Bally’s (Gamesys) puts Double Bubble Bingo, Jackpotjoy, Monopoly Casino, Rainbow Riches Casino and Virgin Games on a single platform. Its welcomes typically follow the “deposit £10, play with more” formula, and existing players see frequent small promotions. When an offer in that mould takes the form of spins, the arithmetic on this page applies directly: the £10 stays your own money, and 100 spins at 10p add £9.60 on average before any wagering, or £5.76 by the formula after 10x.

At Jumpman Gaming’s three sites, Amazon Slots, Dream Jackpot and Prime Casino, a first deposit buys one turn of a prize wheel, which means the advertised figure is the top prize, not what a typical player receives. If a wheel’s top segment shows 100 spins, value the offer on what most players land on, not on the segment in the advert.

Sportsbook-led groups: casino spins tied to a first deposit

Flutter’s betting-first names, Sky Bet, Betfair and Paddy Power, as a rule link their casino welcomes to a first deposit or stake. bet365, sportsbook first and casino second, and Betway, which sells both under one brand, also use deposit-based casino welcomes. Entain’s high-street bookmakers, Ladbrokes and Coral, sit in a group that also runs Gala Casino, Gala Bingo, Foxy Bingo, PartyCasino and bwin, with several brands behind one account structure, so one welcome offer per group is the norm. The mixed-product ban matters most to these groups: since 19 January 2026, “bet £10 on football, get 100 casino spins” is exactly the kind of cross-product promotion a licensed operator can no longer run.

Casino-first and mobile-first brands: where no-deposit spins come from

Sky Vegas, Flutter’s casino-first brand, is the one in its group most associated with no-deposit spins, and 888 Casino, online since 1997 and now part of evoke with William Hill and 777 Casino, spent a decade advertising them. Kindred’s 32Red is casino-first as well. Brands like these are where a licensed no-deposit spin offer is most likely to come from, but the licensed norm for no-deposit spins is still 5 to 20, not 100. The LeoVegas group, owned by MGM Resorts and built mobile-first, runs LeoVegas, BetMGM and Bet UK; BetMGM arrived in Britain in 2023 using LeoVegas’s licence and platform, so the same licence holder answers for both.

No-wagering brands: fewer spins, cash winnings

PlayOJO (SkillOnNet) and MrQ (Lindar Media) work from the opposite end: no wagering on any bonus, so spin winnings are cash, with spin counts that tend to be smaller. Against a 100-spin offer at 10x the comparison is direct. Sixty no-wager spins at 10p have the same formula value, £5.76, and in the simulation even 50 no-wager spins have a median of £3.10, where 100 spins at 10x have a median of zero.

With your own money in, check the licence holder’s record

A deposit package puts £10 to £20 of your own money in the account, which makes the licence holder’s record more relevant than it is for a no-deposit offer. The Commission publishes enforcement action against licence holders rather than brands, and the largest fine or settlement for each runs from bet365 (£582,120, 2024) through Betfred (£3.25m, 2023), Kindred (£7.1m, 2023), 888 (£9.4m, 2022) and Betway (£11.6m, 2020) to Entain (£17m, 2022) and William Hill (£19.2m, 2023). Those figures show that the regulator acts; they are not a ranking of offers.

Betfred, Grosvenor Casinos (Rank), Genting Casino and Admiral Casino (Novomatic) have a physical presence on British high streets, which puts them among the simplest brands to check and the least likely to vanish. NetBet, 10bet, Pink Casino and Magic Red, like other licensed names, show the licence holder and the Commission account number at the bottom of every page, so the register can confirm who you are paying before the deposit goes in.

Offshore “100 free spins no deposit” offers: what they really pay

The no-deposit version of this headline belongs mostly to casinos without a licence for Great Britain. Their offers look larger because the terms behind them are heavier: wagering of 30x to 60x is common, no-deposit bonus “chips” usually cap withdrawals at £100 or less, and none of it is covered by GamStop, the 10x cap or a UK complaints body. Serving British customers without a Commission licence is an offence for the company, not for the customer, yet the customer is the one who loses the protections a licence brings.

The brands change, but the patterns repeat, and none of the following is licensed in Great Britain. Kinghills and NineWin are recent arrivals from a family of sister sites operated by companies registered in Curaçao; neither has a public track record, and both reach UK players via “not on GamStop” listings. Mystake, Goldenbet, Rolletto, Donbet and Velobet share one operator, Santeda International B.V., under a Curaçao licence: not on the UK register, not connected to GamStop, open to cryptocurrency, with uncapped wagering and no route for the Commission to act on a complaint. Rainbet (RBGAMING N.V., Anjouan licence) is built around crypto deposits. Roobet and Gamdom began in the trade in gaming skins and now run Curaçao-licensed crypto casinos; a British customer who sends coins there has no regulator to complain to, no ombudsman and no bank protection on the payment.

The simulation puts numbers on the typical terms. One hundred spins at 10p with 35x wagering finished 6.3% of the time at 10p stakes, with an average of £6.56 and a median of zero, and that run had no cash-out cap. By the formula, 40x gives −£5.76 and 60x gives −£13.44. The simulated £100 no-deposit chip, played on Model A at £1 a spin with a £100 withdrawal cap, was cleared by 6.3% of sessions at 40x (average £6.17) and by 4.6% at 60x (average £4.55). Either kind of offshore “100 free” ends with nothing for well over 90 players in 100, and the cap stops even the rare finisher at £100. For how such headlines are built, see the homepage section on offers that are fake or misleading.

Our ranking sits on the offshore side of that line as well: its casinos hold licences from Anjouan, Curaçao or Costa Rica, and each card names the one that applies. The offer is where they part company with the sites above, since every ranked package needs a deposit of £20 or €20 rather than handing out a no-deposit chip. The missing protections are shared, so weigh the licence line on a card as carefully as its spin count.

What each clause of a 100-spin package does to its value

The terms below are an illustration written for this page, not any casino’s real wording. They are assembled from the kinds of clause that decide the value of a batched deposit package, and the right-hand column shows what each one does to the numbers.

Clauses 2, 3 and 5 are where a 100-spin package differs from a small no-deposit offer: the count arrives in instalments, each instalment can be lost, and each may carry its own requirement. Read them together, then put the number of spins you will really collect into the calculator above.

How to claim 100 free spins, step by step

A 100-spin package involves your own money and several days, so the order matters more than it does for a handful of no-deposit spins. At a UK-licensed casino it runs like this:

1. Confirm the licence first. The footer of a licensed site names the licence holder and gives a Gambling Commission account number, which the Commission’s public register will confirm. Any wagering above 10x in the offer’s terms means you can stop there.
2. Open the account and get verified. Since 7 May 2019 no one may gamble at a licensed site until age and identity are confirmed, and that includes spins bought with a deposit. Automated checks clear most people; the rest are asked to upload a document.
3. Set the deposit limit you are prompted for. Since 31 October 2025 every new customer is asked to set one before the first deposit. A package that needs £10 or £20 is a good moment to decide what the month’s limit should be, not just the offer’s.
4. Make the qualifying deposit. Use a debit card or another accepted method; credit cards have not been accepted for gambling since 14 April 2020, and cryptocurrency is not among the methods licensed sites offer. Deposit the minimum the offer asks for unless you meant to deposit more anyway.
5. Collect each batch on the named slot. Note when each batch lands and when it expires. Ten spins take 25 seconds at the 2.5-second minimum, and 20 spins take 50.
6. Choose how to play any wagering. In the simulation, 10x at 10p stakes finished 16.0% of the time and at 50p 9.0%, with larger results for the finishers at 50p. Decide before you start rather than raising stakes to chase a balance.
7. Withdraw what converts. Check the minimum withdrawal and any cap on converted winnings, then take the money out rather than leaving it to be played.

Red flags to check before depositing for 100 spins

• “100 free spins, no deposit” with wagering above 10x. No licensed casino may ask for more since 19 January 2026, so the offer comes from outside UK regulation.
• “Up to 100 spins”. A prize wheel or a tiered offer: the headline is the best case, and most players land on less.
• A sports bet to unlock casino spins. Since 19 January 2026 a promotion may not require more than one type of gambling.
• Ten daily batches with 24-hour expiry. Not illegal, but the offer is only worth what you will really collect. Ten visits in ten days is a commitment worth pricing before you deposit.
• A low conversion cap on wagered winnings. The average after 10x rests on finishes of about £47. With only 16% finishing, a £30 cap limits the average to £4.80 at most, and a £20 cap to £3.20.
• Deposits in cryptocurrency. A site that takes them is in all likelihood not licensed in Great Britain: crypto is not banned outright, but licensed casinos do not offer it, and the Commission only started looking at a possible route in 2026.
• “No verification needed”. Verification before play is a licence condition, and free spins are not exempt.
• A footer with no licence details. Without a licence holder and account number there is no way to confirm who holds your deposit.

The common thread is that a large spin count is easy to advertise and expensive to deliver, so the terms that make it affordable for the casino are where the value goes. Read them before the deposit, not after.

100 spins or a nearby offer: which gives more value

The comparison below uses the site’s standard figures: 10p spins, 96% RTP, Model A for the simulation, and play-through at 10p stakes for the spin and cash rows. The formula column compares the offers on paper; the last three columns show what usually happens. If a deposit is acceptable, deposit £10, get 100 free spins works through the deposit version of this count, with the £10 and the spins in one ledger.

Size helps less than the headlines suggest. Doubling the count from 100 to 200 spins at 10x doubles the formula value but lifts the finish rate only from 16.0% to 21.0%, and the median stays at zero all the way up; the guides to 120 free spins for real money, 150-spin packages and 200 free spins cover how those bigger bundles are split across days and deposits. Removing the wagering does far more: the same 100 spins with no wagering have a median of £6.90, and even 70 no-wager spins beat 100 spins at 10x on the formula (£6.72 against £5.76) and on the median (£4.58 against zero), though not on the simulated average.

The two cash rows need a word of care. A free £10 no-deposit bonus at 10x is worth £6.00 by the formula, 24p more than 100 spins at 10x, and needs no deposit at all, but it is rarely offered. A 100% deposit bonus on £10 has the same £6.00 formula value; in the simulation, where deposit and bonus were played together at 20p, a third of sessions finished and the average ended £7.86 above the deposit, but 73.9% ended at or below the £10 that went in. That last figure is the reason a match is not a free offer, whatever it adds on average.

Playing safely while a batched offer runs

A batched offer brings you back to the site every day it runs, and every visit is a chance to deposit again. Recognise that before you start: collect the spins, decide in advance what happens to any winnings, and never treat a new batch as a reason to top up a balance.

The deposit that unlocks a 100-spin package is also the point at which a licensed casino must prompt you to set a deposit limit, a rule since 31 October 2025. Set the limit for the month, not for the offer. The legal stake ceilings (£5 a spin, or £2 if you are 18 to 24) limit single bets; a time-out pauses the account for a period you choose; and GamStop, compulsory for online operators since 31 March 2020, blocks every licensed site at once. Offshore “100 free spins” sites sit outside GamStop, which is why they are marketed to people who have used it.

Wagering is where time and money run away. At 10p a spin, 10x on £9.60 is at least 40 minutes of play, and 84% of simulated sessions still ended with nothing. If you notice yourself depositing again to chase what a bonus balance lost, that is the moment to stop. The National Gambling Helpline is on 0808 8020 133.

How we worked out the numbers

Two kinds of figure appear on this page, and they answer different questions. The paper values are arithmetic. Spins × spin value × RTP gives the average winnings, B. B × (1 − W × (1 − RTP)) gives what is left after a requirement of W times, on the assumption that every player stakes all of it. W × B gives the play-through, and the number of spins it needs × 2.5 seconds gives the shortest legal time to clear it. Unless a different RTP is named, the slot returns 96%, and every amount is rounded to the penny.

The spread of results comes from simulated play on Model A, whose settings are 96% RTP, a win on 27.9% of spins, a bonus round roughly every 170 spins and a top prize of 2,500 times the stake. For the 100 spins on their own, 400,000 sessions were run. Every wagering row is a separate run of 100,000 sessions in which each session bets its own winnings at one stake until the requirement is met or it can no longer afford a spin. Dividing a row’s average cash by its finish rate gives the finishers’ average. The batch table multiplies out the 10-spin and 20-spin wagering runs as if each batch were independent. The share of Model A’s return that comes from its bonus round is read from the model’s outcome table, and Model D (96% RTP, low volatility, bonus round about once in 120 spins, 200x top prize) provides the contrast. The match row comes from the site’s separate deposit-match simulation.

Three limits apply. The models describe volatility rather than any real game, because real pay tables are not public. Caps on converted bonus winnings were left out of the simulation, so an offer with such a cap is worth less than the averages here suggest. And batch terms in the wild vary more than two table rows can show. For how offers are assessed and ordered across the site, see our method for evaluating and ranking offers.
