Pragmatic Slots UK: The Best Pragmatic Play Games by Type, Where to Play Them and the 1000 Versions Explained (October 2026)

Quick answer: the best Pragmatic slots and where to play them

• Pick the type before the title. For fishing free spins with money symbols, Big Bass Splash and Bigger Bass Bonanza pair the series’ top default of 96.71% with published ceilings of 5,000x and 4,000x. For multiplier tumbles, Gates of Olympus 1000 keeps the original’s 96.50% and publishes 15,000x; for cluster pays, Sugar Rush also runs at 96.50%.
• Read the RTP version on the information screen. The casino chooses it, not you. Big Bass Bonanza at 94.6% costs £5.40 per 1,000 spins at 10p on average, against £3.29 at 96.71%, a wider gap than separates any two titles at their defaults.
• Take a 1000 version for the ceiling, never for the price. Big Bass Bonanza 1000 publishes 20,000x against the original’s 2,100x for 20p more per 1,000 spins at 10p. The trade is in session length: on the site’s model slots a £20 bankroll at 10p lasted a median 926 spins on the model built to Big Bass Bonanza’s figures and 611 on a high-volatility model with a 5,000x ceiling.
• Compare the ranking’s cards on wagering. The packages there carry wagering of 35x to 40x. At 35x, every £20 of bonus means £700 of stakes, which costs £23.03 on average on a 96.71% game and £27.51 on a 96.07% one, so clear a bonus on the higher-RTP titles and read the terms for excluded games and the largest bet allowed.
• Know the catch. The ranked casinos hold offshore licences, so none of the British rules on this page binds them: the £5 and £2 stake caps, the 2.5-second minimum, the bar on bonus buys, GamStop and the 10x wagering cap all come with a Gambling Commission licence and with nothing else.

Pragmatic slots are the video slots made by Pragmatic Play, a Gibraltar company whose product list puts slots next to live casino, Drops & Wins, jackpots, crash and arcade games. Its slot catalogue is organised around series. Big Bass is a fishing game first released in December 2020, with 14 titles in our sheet up to September 2026. Gates of Olympus, a pays-anywhere game built on multipliers, launched in February 2021 and has had three follow-ups. Sweet Bonanza 1000, Sugar Rush and Starlight Princess complete the list, alongside six new games from August and September 2026.

The returns sit in a narrow band. Across the 23 titles with a published default RTP, the range runs from 96.07% to 96.71%, which over 1,000 spins at 10p means an average cost of £3.29 to £3.93; twelve of the 23 sit between 96.50% and 96.54%. The default is not the whole story, though. Big Bass Bonanza is also supplied at 95.67% and 94.6%, the casino rather than the player chooses which version runs, and only the game’s information screen shows the choice.

The catalogue’s defining pattern is the high-ceiling remake. Big Bass Bonanza 1000 publishes a 20,000x maximum against the original’s 2,100x, at a default of 96.51% against 96.71%. Big Bass Splash 1000 raised 5,000x to 25,000x. Gates of Olympus went from multipliers of up to 500x to 1,000x and, in September 2026, 2,500x. Because the return stayed almost where it was, a bigger top prize usually means more of the same RTP sits in rare results and less in ordinary sessions, and the model-slot comparison further down shows what that does to a session.

In Great Britain these games run under the general slot rules: no bonus buys (Pragmatic reserves those for “select markets”), no stake above £5 a spin, or £2 for players aged 18 to 24, no autoplay or turbo, and at least 2.5 seconds per spin. The only operator statements about Pragmatic games in our fact sheets come from Entain, which agreed on 25 November 2025 to bring the Big Bass series into its Ladbrokes and Coral shops.

What to compare on each Pragmatic slot

Two Pragmatic games with similar artwork can differ in price, in the shape of their results and in the rules around them, and none of that shows in a lobby thumbnail. Each check below says where the answer sits and what it is worth in this guide’s own figures.

Two rows set most of the cost. The RTP version prices every spin, and the wagering on a bonus decides how many spins you have to buy: at 40x, £20 of bonus becomes £800 of stakes, an average cost of £26.32 on a 96.71% game against £31.44 on a 96.07% one. The other rows decide the shape: how much of the return waits in one rare top prize, and how long a small deposit lasts on the way there.

The best Pragmatic Play games by type, and all 24 compared

Most Pragmatic slots fall into a handful of types, and inside each type the published figures separate the titles more clearly than the themes do. The picks below take the highest default RTP within each type among the 24 verified games, then the published ceiling. They are picks on the numbers, not on popularity, and each still needs checking against the version a casino actually runs.

One pattern runs through the picks. The highest defaults belong to the early Big Bass games, while the five titles at 96.07% are the dearest in the list, 64p more per 1,000 spins at 10p than a 96.71% game. A pick with a bigger ceiling, such as either 25,000x game, is a choice about the shape of results rather than the price, which is what the section on 1000 versions measures.

Who makes Pragmatic slots

Pragmatic Play is headquartered in Gibraltar and describes its games as “certified or licensed in over 30 jurisdictions”. That tells you where the games have been approved; it says nothing about the casino in front of you. A British player is protected by the casino’s Gambling Commission licence, not by where the game was certified, which is why the footer check comes first in the step-by-step section below. The product list, from slots and live casino to Drops & Wins, jackpots, crash and arcade games, matters for one rule in particular: the UK stake limits cover online slots, not every product a provider makes.

All 24 Pragmatic games at a glance

Grouped by series and listed in order of announcement within each group. “Not published” means the provider material we checked gives no figure; where a game publishes a multiplier or money-symbol ceiling instead of a maximum win, that is shown in brackets.

What the full list tells you when choosing

Read as a whole, the table describes a provider that varies almost everything except the return. Of the 24 games, 23 have a published default RTP: four at 96.71%, one at 96.70%, five at 96.07%, one at 96.46% and twelve between 96.50% and 96.54%. The median is 96.51%. The full range is 0.64 of a point, the difference between an average cost of £3.29 and one of £3.93 over 1,000 spins at 10p, or £32.90 and £39.30 at £1.

Ten of the 24 publish a maximum win, from 2,100x (Big Bass Bonanza) to 25,000x (Big Bass Splash 1000 and Sweet Bonanza 1000). None of the six 2026 games does; for five of them Pragmatic publishes a multiplier or money-symbol ceiling instead. Volatility is described for only three: Big Bass Bonanza is classed as medium-high, Big Bass Bonanza Megaways as high, and the first Gates of Olympus as highly volatile. Big Bass Bonanza is the only game here with published lower-RTP versions, at 95.67% and 94.6%, which means none were found for the others in the material checked, not that none exist.

The Big Bass rows are also a reminder that a fact sheet is a floor, not a census. Pragmatic called Big Bass Hold & Spinner Megaways, announced in August 2023, “the landmark tenth release” in the franchise; it is the ninth Big Bass game in our list, so at least one earlier title is not in it.

The Pragmatic series game by game: Big Bass, Gates of Olympus, Sweet Bonanza and the rest

Big Bass: fishing free spins in at least 14 versions

The first Big Bass Bonanza, released in December 2020, is a 5×3 fishing game. Three, four or five scatters award 10, 15 or 20 free spins, and every fourth wild retriggers the round with multipliers of 2x, 3x and then 10x. Its default RTP is 96.71%, with versions at 95.67% and 94.6%; it is classed as medium-high volatility; its maximum win is 2,100x. What followed changed one dial at a time: a fourth row and a 4,000x Goldfish scatter in Bigger Bass Bonanza (2021), Megaways in Big Bass Bonanza Megaways (2021), up to five random modifiers before the free spins in Big Bass Splash (2022), golden wilds in Big Bass Keeping it Reel (2022), a hold-and-spin coin bonus in Big Bass Hold & Spinner (2023), sticky multipliers of up to 50x in Big Bass Floats My Boat (2024), and money symbols worth up to 1,000x in the three 1000 games of 2025 and 2026 (the first game’s went up to 2,000x).

Big Bass is also the one Pragmatic family an operator has spoken about publicly in our sources. In November 2025 Entain agreed to bring it into its Ladbrokes and Coral shops, a first for the series in any major operator’s retail estate, and reported that every title regularly sits among its 20 leading games at those two brands. Each game, the series’ RTP history and the shop deal are covered in depth on the Big Bass slots page, and promotional spins on the original game are valued under 20 free spins on Big Bass Bonanza.

Gates of Olympus: for players who want multiplier tumbles

The 2021 original has no paylines. Its 6×5 grid pays for any 8 or more matching symbols wherever they land, winning symbols tumble away and are replaced from above, and multiplier symbols worth 2x to 500x can appear. Four or more scatters award 15 free spins. Pragmatic describes it as highly volatile; the default RTP is 96.50% and no maximum win is published.

Three follow-ups have pushed the multipliers rather than the return. Gates of Olympus 1000 (December 2023) raised them to 1,000x, kept the 96.50% default and publishes a 15,000x maximum. Gates of Olympus POP (August 2026) switched to a 3×5 layout, kept multipliers at a 1,000x ceiling and added jackpot prizes as large as 25,000x, at 96.54%. Gates of Olympus 2500 (September 2026) returned to the 6×5 pays-anywhere grid, lifted the multipliers to 2,500x and added a wheel that picks one of two free-spins modes, at 96.51%. In five and a half years the multiplier ceiling has grown fivefold while the default RTP has moved by no more than 0.04 of a point.

Sweet Bonanza 1000: a 25,000x ceiling on candy bombs

Announced in June 2024, Sweet Bonanza 1000 defaults to 96.53% and publishes a 25,000x maximum, the joint highest in the catalogue with Big Bass Splash 1000. Its candy-bomb multipliers reach 1,000x, which Pragmatic presents as ten times the original’s, putting the original’s at up to 100x. The first Sweet Bonanza’s RTP and maximum win are not in our sheet, so the remake can be compared with it only on the multipliers.

Sugar Rush and Starlight Princess: grid multipliers at 96.50%

Sugar Rush (June 2022, 96.50%) is a 7×7 cluster-pays game, paying for groups of matching symbols rather than lines, with multipliers attached to grid positions that double each time, up to 128x. Starlight Princess (96.50%; release date not published) has multipliers of up to 500x, the same ceiling as the first Gates of Olympus. Neither publishes a maximum win.

The newest Pragmatic slots: six 2026 releases

Six games arrived between 13 August and 28 September 2026: Harvest Moon: Grave Profits (96.50%; money-collect respins and wild multipliers up to 1,000x), Eastern Fury (96.53%; a 5×5 grid with expanding wilds worth 2x to 100x on reel five), Gates of Olympus POP (96.54%), Helios: Triple Sun (96.46%; tumbles with up to three modifiers), Big Bass Vegas 1000 (96.53%) and Gates of Olympus 2500 (96.51%). The buy features that Pragmatic’s announcements reserve for “select markets” are not offered in Great Britain. How these games compare with other providers’ 2026 releases, and with slots of a decade ago, is set out under new online slots.

Original or 1000 version? Bigger ceilings at almost the same price

Pragmatic’s remakes with a number in the title follow one pattern. The number is the game’s largest multiplier or money-symbol value, the published ceiling or multiplier rises between two and ten times over, and the default RTP stays within a fraction of a point of the original’s. The first table puts the pairs side by side; the cost column is the average loss on 1,000 spins at 10p, that is £100 of stakes multiplied by the house’s share.

Where both games in a pair publish a maximum win, the ceiling rose at least fivefold: 9.5 times from Big Bass Bonanza to its 1000 version, 5 times from Big Bass Splash to its own. The default RTP moved the other way, down by 0.20 and 0.19 of a point, which adds 20p and 19p to the average cost of 1,000 spins at 10p, or £2.00 and £1.90 at £1. The Gates of Olympus line raised its multiplier ceiling twice, to 1,000x and then 2,500x, at defaults within 0.01 of a point of the original’s 96.50%. In price, the remakes are the same games; in shape, as the rest of this section shows, they are not.

What each top prize is worth at your stake

A published maximum is a multiple of the stake, so its value in money depends on the stake, and in Great Britain the stake has a legal ceiling of its own: £2 a spin for players aged 18 to 24 and £5 for those aged 25 and over.

At the 10p stake of a typical promotional free spin, the 1000 remake turns Big Bass Bonanza’s £210 top prize into £2,000. At the UK stake caps the remakes’ figures run to five and six digits. How often they land is not published, and the next table shows why that missing number matters more than the ceiling itself.

Who pays for a bigger top prize

A slot’s RTP is the sum of everything it pays, each prize multiplied by how often it lands. The top prize therefore uses up a share of the RTP equal to its size times its frequency. Pragmatic does not publish those frequencies, so the table uses three hypothetical ones to show the scale; none of them describes a real game.

Two things follow. A ceiling ten times higher that takes the same slice of the return must land ten times less often: a 20,000x prize landing once in 100,000 spins would use 20 points, about a fifth of everything a 96.51% game pays back. And the total cannot grow, because Big Bass Bonanza 1000’s default of 96.51% is no higher than the original’s 96.71%. If the top prize and the large wins just below it take a bigger slice, the ordinary wins have to give one up. Pragmatic does not publish how its 1000 versions share out their return, so the arithmetic shows the constraint, not the design.

How long your money lasts: three model slots compared

Real pay tables are not public, so this site uses model slots: outcome tables built to a stated RTP, volatility class and maximum win, not copies of real games. Three of them span the range that matters here. Model D is a low-volatility slot returning 96% with a 200x ceiling. Model C was built to match Big Bass Bonanza’s published RTP (96.71%), medium-high volatility and 2,100x maximum. Model B mirrors the published figures of Book of Dead: a 96.21% RTP, high volatility and a 5,000x ceiling. Their returns are similar; what differs is how much of each return sits in rare results. The structure rows come from the model definitions, the 100-spin rows from 400,000 simulated sessions per model, and the bankroll rows from 40,000 sessions per model, each played at a fixed 10p until the balance ran out or 1,440 spins (one hour at the 2.5-second minimum) had passed.

Read from left to right, the table is the 1000 effect in miniature. Moving from Model C to Model B raises the ceiling 2.4 times and the share of the return paid by wins of 100x or more from 20.7% to 37.4%. The average of 100 spins barely moves, £9.66 against £9.62, but the median falls from £7.18 to £5.88. A £20 bankroll at 10p lasts a median 611 spins instead of 926, and the share still playing after 500 spins drops from 86.1% to 62.5%. In exchange the top end fattens: 1.5% of Model B sessions turned 100 spins into £100 or more, against 0.2% on Model C, and the 99th percentile rose from £83.95 to £104.52. Model D runs the other way: a median of £8.92, almost every bankroll still going after 500 spins, no 100-spin session reaching £100, and few bankrolls doubling within the 1,440-spin limit because so little of its return arrives in lumps.

Two cautions keep the comparison honest. Model C’s RTP is half a point higher than Model B’s, worth 50p per 1,000 spins at 10p, which explains a little of the gap in bankroll life but not the shift in the median or the tails. And no model here has a 20,000x ceiling: the 1000 versions publish maximum wins three to five times Model B’s, while how much of their return sits in rare results is not published. The models show the direction of the change, not its size.

Original or 1000: how to choose

For almost the same price, within 20p per 1,000 spins at 10p, a 1000 version is likely to sell a different shape of result: a larger prize at the very top, paid for by thinner ordinary sessions. Neither shape is the better one. On the models’ evidence, a player with a small budget who wants the session to last gets more spins from a lower-ceiling game, while a player who accepts that most sessions end early, in exchange for a rare large result, is choosing the 1000 shape knowingly. The one thing a ceiling never changes is the average cost, which is set by the RTP version on the information screen.

In practice the guidance comes down to three questions. If the deposit is small and the aim is an evening’s play, start with an original at its top default, such as Big Bass Splash or Big Bass Bonanza at 96.71%. If you would trade a shorter session for a five- or six-figure ceiling at the stake caps, a 1000 version is the honest choice, provided the information screen shows its default rather than a lower version. And if a bonus is being cleared, the wagering multiplies whatever the RTP costs, so the higher default wins whichever ceiling comes with it.

How a UK licence changes a Pragmatic slot: stakes, speed and bonus buys

The version of a Pragmatic game a British player sees is shaped by the Gambling Commission’s rules rather than by the provider’s marketing. Six of those rules matter most for this catalogue.

• No bonus buys. Pragmatic’s announcements describe buy features for “select markets” only. The Commission’s warning of 17 January 2020 keeps them away from British customers: it had found one game asking more than £3,000 for entry to its bonus round, and all six operators it approached dropped the option. In Great Britain the free spins of Big Bass or Gates of Olympus are reached only by landing the scatters.
• Stakes are capped on slots, not on everything. Since 9 April 2025 the limit is £5 a game cycle for players aged 25 and over, and since 21 May 2025 £2 for those aged 18 to 24. That puts Big Bass Bonanza 1000’s 20,000x at no more than £100,000, or £40,000 for younger players. The limits cover online slots, which the guidance defines as reel-based games played online, and the guidance says they do not apply to other casino games such as roulette or blackjack. Pragmatic also makes live-casino, crash and arcade games, so the cap on its slots is not a cap on everything it makes.
• Speed is limited. Since 31 October 2021 autoplay has been banned, each spin must last at least 2.5 seconds, and turbo, quick-spin and slam-stop buttons have gone. The ceiling is therefore 1,440 spins an hour: a 10p player can put no more than £144 through any Pragmatic slot in that time, for an average cost of £5.03 at Big Bass Bonanza 1000’s default.
• No false wins, and the score stays on screen. Sounds and images may not celebrate a return equal to or below the stake, and the session’s total losses or wins and the time played must be displayed throughout, however busy the multiplier animations get.
• Verification first. Since 7 May 2019, age and identity have to be checked before any play, including the free-to-play demos that some players use to learn a Pragmatic game’s features.
• Promotions follow the general rules. Drops & Wins is on Pragmatic’s product list. Whatever promotion a UK-licensed casino runs, since 19 January 2026 any wagering attached to it is capped at 10 times, and it may not require two kinds of gambling.

None of these rules fixes the RTP. Pragmatic supplies Big Bass Bonanza at 96.71%, 95.67% and 94.6%, and the operator picks; only the game’s information screen tells you which version is in front of you. Of everything on this page, that single figure moves the average cost most: the step from 96.71% to 94.6% adds £2.11 per 1,000 spins at 10p, more than ten times what the step from the original to the 1000 version adds.

Price your Pragmatic session before you play

To price a session on a Pragmatic slot, fill in the stake, your likely spins per hour, the hours and the RTP read from the game’s information screen. It reports how many spins that comes to, the total you stake, the average loss for the session and per hour, what the game keeps from each spin on average, and how much comes back. It starts at 10p a spin, an assumed 600 spins in one hour and 96.51%, the default of Big Bass Bonanza 1000 and of Gates of Olympus 2500.

At those settings the hour costs £2.09 on average. Enter 96.71 for the original Big Bass Bonanza and the figure falls to £1.97; enter 94.6, its lowest published version, and it rises to £3.24. The version moves the cost far more than the step from original to remake does. Like every average, the result hides the spread: the model comparison above shows how differently individual sessions on a high-ceiling game turn out.

Pragmatic slots at UK-licensed brands: what the record shows

Which casino carries which Pragmatic game, and at which RTP version, is not published anywhere we can verify, so the lobby and the information screen remain the place to check. One operator has made public statements about Pragmatic content, and they are reported here as that operator’s statements. For every other brand, the useful facts concern the licence holder, the group and its record.

Entain: the one operator on record about Pragmatic games

Under an agreement dated 25 November 2025, Entain undertook to bring Big Bass Bonanza, Big Bass Splash, Big Bass Hold & Spinner and other Big Bass titles to more than 2,700 Ladbrokes and Coral shops; no major operator had taken the series into its retail estate before. In announcing it, Entain described every title as a consistent member of its top 20 games for those two brands and named Big Bass Splash as its top-performing UK online slot of 2025. Both claims measure what Entain’s own customers chose to play, not what the games return. In the same group sit PartyCasino, Party Poker, bwin, Sportingbet, Gala Casino, Gala Bingo and Foxy Bingo, with several brands behind one account structure, which is why one welcome offer per group is the norm. Entain’s largest Commission fine or settlement is £17m, from 2022.

At every other brand, check the version on screen

Because Pragmatic supplies Big Bass Bonanza at three RTPs, the same title can carry three prices. Over 1,000 spins at £1 the average cost is £32.90 at 96.71%, £43.30 at 95.67% and £54.00 at 94.6%, a £21.10 spread decided by the operator and invisible from the lobby. What a brand fact can tell you is the structure behind the logo and the record of the company holding the licence:

A prize wheel’s top segment and a 1000 remake’s ceiling are the same kind of number: the most that can happen, not what usually does. Other licensed brands, among them Casumo, NetBet, Pink Casino, Dream Vegas, Videoslots and Mr Vegas, print their licence holder and Gambling Commission account number in the site footer, where the public register can confirm them. All the brands in this section check age and identity before any play, take part in GamStop, refuse credit cards, leave crypto out of the cashier, and have worked to a 10x wagering ceiling since 19 January 2026.

Playing Pragmatic slots offshore: the rules you give up

Pragmatic’s certifications describe the games, not the sites that offer them. A casino without a Gambling Commission licence sits outside every rule on this page, whatever titles appear in its lobby, and that includes the four casinos in our ranking, whose cards show licences from Anjouan, Curaçao or Costa Rica. For a Pragmatic slot the two rules that fall away first are the ones with the most money attached: the ban on bonus buys and the stake cap.

The stake cap is the easier of the two to put in pounds. Assuming 600 spins an hour on a 96.51% game, £5 a spin loses £104.70 an hour on average; £20 a spin, four times the British ceiling, loses £418.80. Bonus buys, which the Commission’s warning keeps away from British customers, turn the feature into something bought rather than waited for. Add uncapped wagering on any bonus, no GamStop link, no eight-week deadline for complaints followed by an independent ADR provider, no 2.5-second floor and no on-screen net position.

None of the following offshore brands is licensed in Great Britain. Santeda International B.V. runs Mystake, Goldenbet, Rolletto, Donbet and Velobet under a Curaçao licence; none of the five appears on the UK register or links to GamStop, all take cryptocurrency, wagering is uncapped, and a complaint about them is beyond the Commission’s reach. Kinghills and NineWin are newly launched sister sites from a Curaçao-registered network, with no public track record, promoted to British players on “not on GamStop” pages. RBGAMING N.V. operates Rainbet, a crypto-first casino, under a licence from Anjouan in the Comoros. Roobet and Gamdom, Curaçao crypto casinos with roots in the gaming-skins market, leave a British customer without a regulator or an ombudsman, and a crypto deposit carries no bank protection. It is the operator that breaks the law by serving British customers without a Commission licence; the player faces no prosecution, but forfeits every protection listed above.

Reading a Pragmatic slot before you stake

Pragmatic’s titles carry information once the naming is decoded. Each meaning below is what the word stood for in the games in our fact sheet; where only one game carries a word, treat it as an example rather than a rule.

With the name read, six checks take a few minutes at a UK-licensed site:

1. Confirm the casino’s licence. The footer should name the licence holder and its Gambling Commission account number, and the public register confirms both. A game certified in over 30 jurisdictions does not stand in for this check.
2. Read the RTP in the information screen. Compare it with the defaults in the catalogue: 96.71% for Big Bass Bonanza (with versions at 95.67% and 94.6%), 96.51% to 96.53% for the three Big Bass 1000 games, 96.50% for the first two Gates of Olympus games. A figure below the default means a lower version.
3. Convert the ceiling into pounds. A number in the title signals a higher ceiling at a similar RTP. Turn the published maximum into money at your stake, 20,000x at 20p is £4,000, and treat it as a ceiling rather than a target.
4. Read how the feature starts. The paytable gives the trigger: on the original Big Bass Bonanza three, four or five scatters start 10, 15 or 20 free spins; on Gates of Olympus four or more start 15.
5. Check the stake range, and that nothing is for sale. At most £5 a spin, or £2 if you are 18 to 24, and no option to buy the feature.
6. Price the session and set limits. Use the calculator above, then set a deposit limit, prompted for every new customer since 31 October 2025, and a time limit before the first spin.

Pragmatic slot myths that cost players money

• “Every Pragmatic slot pays 96.5%.” Defaults run from 96.07% to 96.71%, and the version a casino runs can be lower: Big Bass Bonanza at 94.6% costs £5.40 per 1,000 spins at 10p, against £3.29 at its default.
• “The 1000 version pays more.” On Big Bass Bonanza its default is 0.2 of a point lower (96.51% against 96.71%) and its ceiling far higher, which on the model slots’ evidence means thinner ordinary sessions, not a better return.
• “A 2,500x multiplier means big wins are common.” The figure is a ceiling. Pragmatic publishes no frequency for its largest multipliers or prizes.
• “A popular game must pay more.” Entain’s statements measure what its customers played, not what the games return. Big Bass Splash, its top-performing online slot in the UK in 2025, defaults to 96.71%, exactly like the original Big Bass Bonanza.
• “You can buy straight into the free spins.” Not in Great Britain; the Commission warned operators off feature buy-ins in January 2020.

This page follows one provider. The guides around it cut the same games by series, by date, by rank or by offer:

If you already know you like Big Bass, the series page goes deeper on every title; if you are choosing between providers, the ranked and grouped lists set Pragmatic’s games beside other providers’ on the same published figures. This page’s own contribution is the catalogue as a whole and the 1000 effect, which neither list measures.

Keeping a Pragmatic session within budget

Pragmatic’s games are built around moments: a multiplier landing in a tumble, a fisherman collecting money symbols, a wheel picking a free-spins mode. Those moments are rare by design, and a 1000 version raises the size of the largest of them without raising the return. On the high-volatility Model B, half of all £20 bankrolls played at 10p were gone within 611 spins, about 25 and a half minutes at the 2.5-second minimum.

• Set a deposit limit at the prompt before your first deposit, at a level you would not miss.
• Decide the length of the session first. The net position and time played on screen tell you where you stand; use them as a stopping rule, not a scoreboard to chase.
• Keep the stake well below the cap on high-ceiling games. The cost per hour rises in step with the stake, while the chance of the ceiling does not.
• Use the time-out tool licensed sites offer when a run of near-misses on a multiplier game keeps you playing longer than planned.
• Register with GamStop to shut yourself out of all British-licensed online gambling in one step.

How we worked out the numbers

Every game figure on this page was taken from Pragmatic Play’s announcements and game pages and verified in October 2026; Big Bass Bonanza’s RTP versions, volatility class and maximum win are as listed in our main fact sheet. Dates are the dates Pragmatic announced each game. Where the source is silent the tables say “not published”, and nothing has been estimated. Entain’s statements are reported as Entain’s. Rules are the Gambling Commission’s, with the dates it gives.

The average cost of any session is stake × spins × (1 − RTP), which for 1,000 spins at 10p comes to (1 − RTP) × £100. Hourly figures assume 600 spins an hour where stated, against a maximum of 1,440 under the 2.5-second rule. Converting a ceiling into pounds means multiplying the published multiple by the stake. The top-prize table uses hypothetical frequencies and is pure arithmetic: a prize of X times the stake landing once in N spins uses X ÷ N of the RTP.

Points of RTP used = X ÷ N × 100

The session figures come from three model slots built for this site: Model D (low volatility, 96%, a bonus round about once in 120 spins, 200x maximum), Model C (built to Big Bass Bonanza’s published 96.71% RTP, medium-high volatility and 2,100x maximum; once in 180) and Model B (built to Book of Dead’s published 96.21% RTP, high volatility and 5,000x maximum; once in 200). The 100-spin results come from 400,000 sessions per model and the bankroll results from 40,000 sessions per model at a fixed 10p stake, stopped when the balance could not cover a spin or after 1,440 spins. The structure rows, such as the share of the return paid by wins of 100x or more, are computed from the same model definitions. No model copies a real game, and none was built to a 1000 version, since no real pay table is public.
