Big Bass slots in rank order: the return on every title, the ceiling, and what a trip costs

Big Bass in short: which title, what it costs, where to play

• Four titles share the top published return. Big Bass Splash, Bigger Bass Bonanza, the December 2020 original and its Christmas edition all publish 96.71%, which comes to £4.94 of average cost over 750 spins at 20p. Of the four, Big Bass Splash states the largest ceiling at 5,000x, so it is the one to open if nothing else on the list tempts you.
• The five cheapest titles to play are also the oldest. Every game released between October 2022 and March 2024 that publishes a figure at all publishes 96.07%, and that costs £5.90 over the same 750 spins. You are paying 96p for a coin bonus, golden wilds or sticky multipliers, which is a small price if you actually want the feature and a waste if you do not.
• Pay the premium for a ceiling, not for a return. The three 1000 editions sit at 96.51% to 96.53%, between the two older groups on price, and two of them publish the biggest top prizes in the series at 20,000x and 25,000x. At a 20p stake that is £4,000 and £5,000, against £420 on the original.
• Read the information screen before the first spin, every time. The original exists in copies returning about 95.67% and about 94.6% too, and the lower of those turns the same 750 spins at 20p from £4.94 into £8.10. Nothing on the reels tells you which copy you have been handed.
• For somewhere to play, work through the offshore options and search each lobby. Each is a deposit welcome from a casino licensed outside Britain, starting at £20 or €20 with 35x to 40x wagering, where a licensed British site has not been allowed past ten times since 19 January 2026. No such offer lists its games, so no promise about a particular fishing title can be read off one of them.

One rule to keep: stay inside the 96.71% group unless one of the later titles carries a feature you actually want to play, and set a stake that lets the trip run as long as you planned it.

The fourteen titles in rank order

Rank 1 goes to the highest published default return, and where two titles publish the same return the larger published ceiling comes first. That order puts price ahead of prizes deliberately: the return applies to every spin you ever make on the game, while the ceiling is a number most players will never see land. Where Pragmatic publishes no figure, the column says so rather than guessing, and the last title is unranked because neither of its two numbers is published.

Three things are worth taking from that table before any of the detail. The first is how little separates ranks 1 to 5: a penny over 750 spins at 20p, because 96.71% and 96.70% are a hundredth of a point apart. Choosing between those five is a choice about grids and features, not about money. The second is that the three remakes carrying the 1000 suffix are not the cheapest games in the series and never were, so anyone who assumes a newer release returns more has it backwards. The third is that rank 3, the original, is the only title in the series with lower settings on record, which is why it gets a section of its own further down.

The entry at the foot of the table matters too. Pragmatic described the August 2023 release as the landmark tenth game in the franchise and gave it up to 147,456 ways to win, but published neither a return nor a maximum win in the material behind this page. A game you cannot price is a game you cannot compare, and padding the table with an invented figure would be worse than leaving the row honest.

What 750 spins cost on each rung of the ladder

Cost on a slot is multiplication and nothing more. Your stake multiplied by the number of spins gives the money that passes through the game; multiply that by the share the game holds back, which is 100% minus the published return, and you have the average bill. Seven hundred and fifty spins is a useful block to think in, because it is a decent evening rather than a quick look.

750 spins × £0.20 = £150 staked    £150 × 3.29% = £4.94

The same block of spins at three stakes, rung by rung:

Read the table down the 20p column and the shape of the series appears. The first generation charges 3.29p in the pound. The middle generation charges 3.93p, which is about a fifth more per spin and 96p more over the block. The remakes pulled most of the way back to 3.47p, 3.48p and 3.49p, which is between 27p and 30p dearer than the first generation over 750 spins and between 66p and 69p cheaper than the middle one. That is the whole price history of the series in three sentences, and it has nothing to do with the ceilings.

Now read it across. The stake multiplies all of it: the best rung costs £1.23 at 5p and £12.34 at 50p, so moving your stake up from 5p to 50p on the cheapest game in the series costs you four times what moving from the cheapest game to the dearest setting costs at 5p. In other words, the stake selector decides your evening and the game lobby only fine-tunes it. That is worth remembering whenever a page tells you a title is “better value”.

The two bottom rows deserve their own warning, because they belong to one game rather than to the series. Alongside its 96.71% default, Big Bass Bonanza comes in copies returning about 95.67% and about 94.6%, and which one you meet is the casino’s decision rather than yours. On the lowest of those the block costs £8.10 instead of £4.94, a difference of £3.16, which is more than three times the 96p that separates the series’ own best and worst published defaults. Checking takes ten seconds in the game’s information screen, and it is the single most profitable ten seconds on this page. The guide to finding the top-paying version sets out the same check across other titles.

The ceilings in pounds, and the figure nobody publishes

Eight of the fourteen titles publish a maximum win. Multiply it by your own stake and the headline becomes a number you can actually picture, which is the only honest way to read a figure like 25,000x.

Across five years and nine months, from December 2020 to September 2026, the top published prize in the series grew to nearly twelve times its starting size while the published return ended slightly lower than it began. Those two movements are not connected by any arithmetic you can check, because a maximum win tells you how far the tail of a game’s prize distribution reaches and the return tells you what the whole distribution averages. A game can lengthen its tail without paying out a penny more in total, simply by making everything else a little thinner.

And here is the figure nobody publishes: how often any of those ceilings lands. Pragmatic states the maximum win and does not state its frequency, for this series or for any other, which means nobody outside the studio can price it. Treat a ceiling as the furthest point on the map rather than as a destination. The arithmetic you can do is the cost of looking for it, and the cost of looking is the 20p column in the price table above.

The practical reading, if a big number is what you are after: Big Bass Splash 1000 publishes the largest, 25,000x, which is £5,000 from a 20p spin, at 96.52% and 28p a block dearer than the cheapest group. Big Bass Bonanza 1000 publishes 20,000x, £4,000 at the same stake, at 96.51%. Nothing else in the series reaches half of either. If a big number is not what you are after, the first four ranks cost less per spin and that advantage applies to all 750 of them.

How £15 behaves at three stakes on the Bass-style model

An average cost describes thousands of evenings. It says nothing about one. To show the spread, these pages run a model slot called Bass-style, built to the published figures of Big Bass Bonanza, its 96.71% default return and its 2,100x maximum win, with a win of some size on 23.81% of spins and the free-games round arriving on average once in every 165 spins. The real pay table of the game is not public, so the model shows the shape of a fishing slot and not the game itself.

Each line below is 100,000 simulated sessions. Every session starts with £15, plays one fixed stake, and stops when the balance cannot cover the next spin or when 750 spins have gone.

The stake, not the game, decides how long you sit there. At 5p the £15 is 300 stakes and five sessions in six were still running after 750 spins; at 50p it is 30 stakes and seven sessions in ten had finished inside the first 100 spins. Yet the average closing balance barely moves across the three columns, from £13.65 down to £12.67, because a session that runs out of money stops losing money. What the small stake buys is time, and what the large stake buys is a quicker answer.

Look at the middle balance next to the average and you can see the shape of a fishing slot. At 20p the average session closed on £12.67 while the middle one closed on 12p, which is the small change left when a balance can no longer cover a spin. Most sessions end quietly and a minority end large enough to haul the average almost back to the starting stake money.

The 50p column holds the oddest result on the page, and it is worth a moment. At that stake more sessions ended on £50 or more, 4.4%, than ended somewhere between £15 and £50, 1.0%. There is no middle ground left: 30 stakes is not enough money to grind out a small profit, so a 50p session either finds a big round early or it is over. Thirty stakes is too few for a game built around a round that comes once in 165 spins.

The same runs on the original’s lower settings show how much less the version matters than the stake. At 20p, the default kept 15.8% of sessions alive to spin 750, the 95.67% setting 15.0% and the 94.6% setting 14.1%; the share finishing above £15 fell from 12.9% to 12.3% to 11.6%. The version moves those numbers by a point. Going from 20p to 50p moves them by ten.

Waiting for the free games, and what the wait costs

Every title in the series is built around the same moment: scatters land, the fisherman starts collecting the money symbols, and the round pays what the base game has been holding back. On the Bass-style model that round carries 38% of the game’s whole return, which means the other 62% arrives in dribs and drabs while you wait. Pragmatic does not publish how often the round lands in any of the real titles, so the frequency below is the model’s, set at one round in every 165 spins on average.

Two readings come out of that. The first is that a short sitting is mostly a bet on whether the round shows up: open a fishing game for sixty spins and seven times in ten you will close it again without seeing the thing it was designed around. That is the ordinary outcome and not bad luck. The second is that the average gap itself has a price. One hundred and sixty-five spins at 20p puts £33 through the game, which costs £1.09 on average before the round has paid anything at all.

165 spins × £0.20 = £33 staked    £33 × 3.29% = £1.09

That arithmetic is the argument for a small stake on this kind of game, and it is stronger than any argument about returns. A player who needs several hundred spins to give the round a fair chance should be buying those spins at 5p, where 750 of them cost £1.23 on average, rather than at 50p, where the same 750 cost £12.34 and most sessions never get there.

One warning about the later titles. The model is built to the original’s published figures, and the games with ceilings of 10,000x, 20,000x and 25,000x almost certainly park more of their return further out in the tail, which usually means a longer wait and a bigger payoff when the wait ends. Nothing published lets anyone put a number on that, so read the model as the gentler end of what a fishing slot can do.

What each title adds, and whether the price is worth it

The shared machinery is the original’s. Fish on a five-by-three grid of ten paylines carry money values reaching 2,000 times the stake. Land three scatters and the free games begin with ten spins, four scatters bring fifteen and five bring twenty. While the round runs, the fisherman wild sweeps up every fish on screen, and each fourth wild sends the round round again, carrying a 2x multiplier the first time, 3x the second and 10x the third. Pragmatic files the original under medium-high volatility, with the 2,100x ceiling above it.

What the later titles do is add something on top, and the table says what each addition costs you per 750 spins at 20p against the 96.71% baseline of £4.94.

The two free additions are the interesting rows. Bigger Bass Bonanza gives you an extra row of symbols and doubles the original’s ceiling without charging anything extra per spin, and Big Bass Splash adds its random modifiers at the same price. If you like the series and have no strong feelings about features, those two are where the published figures point, and Big Bass Splash leads on those figures because its 5,000x is the largest ceiling available at 3.29p in the pound.

At the other end, the five titles at 96.07% are the dearest in the series and the ones to be deliberate about. Ninety-six pence over 750 spins at 20p is not a disaster; it is the price of a feature, and a coin bonus or a sticky 50x multiplier is a real thing to want. What it is not is better value. Anyone who picks those games because they look newer and busier is paying about a fifth more per spin for the pleasure.

One mechanic the series advertises is simply not available to you in Britain. Pragmatic’s release notes mention an option to buy straight into the free spins “in select markets”, and that is not one of them: the Gambling Commission warned operators off selling entry to a bonus feature on 17 January 2020, after finding a game that charged more than £3,000 to get in, and the six operators it contacted dropped it. If you see a button offering to sell you the round, you are not on a British-licensed site.

Twenty-five spins on a fishing title, valued twice

Spin offers often name a game from this series, so it is worth knowing what a batch is really worth before the terms get involved. Take twenty-five spins valued at 20p each on a title running at 96.71%. The face value is £5, and the average winnings are the face value multiplied by the return.

25 spins × £0.20 × 96.71% = £4.84

Across 250,000 simulated batches on the Bass-style model, the average came in at £4.81 and the middle batch at £2.54. One batch in ten returned 71p or less, one in ten returned £8.37 or more, and the best batch in a hundred returned £51.42. Just under a quarter of batches, 24.2%, got back the £5 face value or more, 7.6% reached £10, and only 0.1% returned nothing whatever.

The spread is the point. The average is simply the face value times the return and tells you nothing a calculator cannot; the middle result, £2.54, is about half the average, because a minority of batches catch the free-games round and most do not. If a casino hands you twenty-five spins on a fishing game, the likeliest single outcome is a couple of pounds.

Now the terms. Say those winnings must be played through ten times at the same 20p stake, which is the most a British-licensed site has been allowed to ask since 19 January 2026. The formula value is the winnings shrunk by the cost of the play-through.

£4.8355 × (1 − 10 × 3.29%) = £3.24

That is the figure if the wagering is completed in full. In 100,000 simulated attempts only 8.7% of batches managed it, because the play-through is run from the winnings themselves and most balances cannot survive ten passes. The average cash left was £4.14, held up by a handful of large results, while 91.3% of attempts ended with nothing at all to withdraw. Both numbers are true and they describe the same thing: a wagered spin batch usually pays nothing and occasionally pays well.

A twenty-spin offer on the first game in the series is valued setting by setting on the Big Bass Bonanza spins page, and the free spins by slot guide explains why an identical batch is worth something different on a calm game and on a spiky one.

Where to play, and the one operator link on the record

Only one operator’s connection to this series can be stated as fact, and it is a big one. Entain announced on 25 November 2025 that the fishing games, among them the original, Big Bass Splash and Big Bass Hold & Spinner, were going into over 2,700 of its Ladbrokes and Coral branches. No shop estate on that scale had ever carried the series. Entain said at the time that every title ranks dependably inside its top 20 games at those two brands, and that during 2025 Big Bass Splash out-performed every other slot it ran online in this country.

Read that carefully, because it is a popularity statement and not a payback statement. It describes how often two brands’ customers open the games. Entain never said what “top-performing” was measuring, and Big Bass Splash publishes 96.71%, the identical default to three of its stablemates. Nor did the announcement say which version of any title those brands install online. The rankings belong to Ladbrokes and Coral customers rather than to the wider market.

Beyond that single documented link, the useful question is what sort of company stands behind the lobby you are opening, because the company settles your account rules and how many welcomes you are entitled to. Two British names attach no play-through to anything they hand you: MrQ, run by Lindar Media, and PlayOJO, run by SkillOnNet, so a batch of spins on a fishing title pays you in money you can take straight out, usually across fewer spins than a rival would offer. Amazon Slots greets a first deposit with a turn of a prize wheel, which makes the advertised prize the best segment on the wheel rather than the one most people land. Sky Vegas is Flutter’s casino-led name and the brand there whose advertising has leaned hardest on spins claimed without paying in, while the group’s bookmaking names, Paddy Power, Betfair and Sky Bet, as a rule hang a casino welcome on money going in first. At Kindred, now part of FDJ United, 32Red takes the casino side and Unibet the sport, and £7.1m from 2023 is the heaviest Commission figure on that group’s record.

Entain reaches a long way past its two shop brands online: Party Poker and PartyCasino, bwin and Sportingbet, Gala Casino, Gala Bingo and Foxy Bingo, a number of which run on shared accounts, so a welcome taken at one can quietly spend your entitlement at the next. The group carries £17m from 2022. Inside evoke sit 888 Casino, online since 1997 and built for a decade on advertising that led with spins needing no deposit, plus 777 Casino, 888sport and William Hill, which joined in 2022; the two largest figures there are £19.2m from 2023 and £9.4m from 2022. LeoVegas, owned by MGM Resorts, was designed around the phone and now carries Bet UK and Pink Casino beside BetMGM, whose British site opened during 2023 on the LeoVegas licence and technology. One Gamesys platform under Bally’s gathers Virgin Games, Jackpotjoy, Monopoly Casino, Double Bubble Bingo and Rainbow Riches Casino, where a welcome is usually a balance to play with rather than a percentage. bet365, privately held in Stoke-on-Trent and the owner of Heart Bingo, puts its sportsbook first and builds casino offers on a deposit, with £582,120 from 2024 on its record, while Betway runs both halves under a single name and carries £11.6m from 2020. Four more trade from addresses you can visit, which makes them the easiest of the lot to confirm and the slowest to disappear: Betfred, carrying £3.25m from 2023, Grosvenor Casinos under Rank, Genting Casino, and Admiral Casino, owned by Novomatic. Casumo, Videoslots, Mr Vegas and NetBet put the name of the company holding their licence, with its account number, at the very bottom of the page, and both take well under a minute to confirm on the Commission’s register.

Whichever of them you open, the rulebook on a fishing spin is identical. Your age and identity are confirmed before any play, free demo rounds included, which has been the rule since 7 May 2019. Your stake stops at £5 a spin from the age of 25 and at £2 from 18 to 24. No spin starts sooner than 2.5 seconds after the last, autoplay is gone, and no turbo or slam-stop button exists to hurry the reels. A return that gives back no more than you staked gets no celebration. Your running position and your time played stay on screen. Nobody may sell you entry to the free games. From 19 January 2026 the wagering attached to a bonus has been capped at ten times the bonus itself, and a single promotion may no longer call for two different products at once.

A fishing lobby outside the British licence

Casinos at this end of the market are regulated elsewhere, and what that changes for a Big Bass player is a list of absences rather than a single headline. No ceiling on your stake, so a spin can cost whatever the lobby allows. No floor under the spin speed, so the reels can turn as fast as you can tap. Autoplay and turbo buttons can come back. The paid entry to the free games that British operators were told to drop in January 2020 may be on sale. There is no on-screen running total, no prompt to set a deposit limit before you pay in, no ten-times ceiling on wagering, and no British body able to take up a complaint if a withdrawal stalls. The terms do say that identity papers are wanted before a first payout is released, which is a fair thing to ask and a thing to settle on your first day rather than your best one.

The ownership is no mystery, which is the one helpful thing about this corner of the market. Santeda International B.V. holds a single Curaçao licence behind five separate shopfronts, Rolletto, Velobet, Mystake, Donbet and Goldenbet, so five logos amount to one counterparty, with nothing capping the wagering and no complaint any British body can take up. NineWin and Kinghills came out of Curaçao-registered families of sister sites recently enough that nobody has a record to read, and they are sold to players here through pages advertising their distance from Gamstop. Rainbet operates as RBGAMING N.V. on a licence from Anjouan in the Comoros and takes deposits in Bitcoin and other coins, which no British licensee does. Gamdom and Roobet are two further coin-first Curaçao casinos, both with roots in the trade in game skins, and a payment made to either in coin has no bank behind it to pull back. Not one of those names is licensed for this country, so a player here keeps the games and gives up everything the licence carries. Doing business in Britain without a Commission licence is the operator’s offence rather than the customer’s, which is cold comfort when a balance goes missing and there is nobody to take the complaint. Our guide to offshore slot sites goes through them one at a time.

The cost side has no ceiling either. At 20p on a 96.71% title a British site can take at most £9.48 an hour from you on average, because the 2.5-second rule caps the hour at 1,440 spins. Remove the stake limit and the spin timer and there is no equivalent figure to quote at all, which is the honest answer to anyone who asks how much faster an offshore lobby costs.

Price your own trip

The calculator opens on this page’s own block: 20p a spin, 750 spins, one sitting, on a game returning 96.71%. Change the return to whatever your information screen shows and the bill moves with it. Type 96.07 for any of the five middle-generation titles, anything from 96.51 to 96.53 for a remake, or 94.6 if the original has been installed at the bottom of its ladder.

Whatever it gives you is an average across a great many evenings rather than a forecast for yours. The session table above is the honest companion to it: on the Bass-style model at 20p the average closing balance was £12.67 while the middle session closed on 12p, and both figures come from the same 100,000 runs.

Keeping the trip the length you planned

A slot has no closing time, which is why a British licensee has to keep your net position and your elapsed time on the screen while you play. Decide before you start which of those two numbers ends the session, and then let it.

Set a deposit limit while nothing is at stake. That choice has had to be put in front of every new customer at a licensed British site before a first payment since 31 October 2025, and a limit chosen in a quiet moment is worth more than a resolution made at spin 400. A time-out shuts one account for a stretch you pick. Gamstop shuts every licensed British site in a single step, every online licensee having had to be part of it since 31 March 2020, and it reaches no casino holding a licence outside Britain, which is the whole of the difference.

If chasing the next round has stopped feeling like a choice you are making, stop for today and put something in place before tomorrow. GamCare answers the National Gambling Helpline on 0808 8020 133, free of charge, in confidence, day or night. GamBan blocks gambling sites on every device you put it on, which covers ground Gamstop cannot. Most banks will refuse gambling payments on your debit card if you switch the block on. Our play safe page keeps all of it in one place.

Where every figure here comes from

Titles, announcement dates, default returns, lower settings, maximum wins, volatility classes and mechanics are all Pragmatic Play’s own, taken from the studio’s game pages and release announcements and logged in this site’s fact sheet during October 2026. Where the studio publishes nothing, the tables say so; no figure here has been filled in by guesswork, which is why the fourteenth title carries no rank. The Entain material comes from that operator’s announcement dated 25 November 2025.

Costs are arithmetic you can repeat: stake multiplied by spins multiplied by the share held back, which is 100% minus the published return. The block used throughout is 750 spins, priced at 5p, 20p and 50p, which is £37.50, £150 and £375 of stakes. The 1,440-spin hour is the most the 2.5-second minimum allows at a British site; no other pace is assumed anywhere on this page.

Simulated figures come from the Bass-style model slot, a model built to Big Bass Bonanza’s published 96.71% return and its 2,100x maximum win, paying something on 23.81% of spins and reaching its free-games round on average once in 165 spins, with 38% of its total return inside that round. The real pay table is not public, so the model reproduces the game’s headline figures and not the game. Session figures are 100,000 runs for each stake, each starting at £15 and ending when the next spin became unaffordable or when 750 spins had gone; the two lower-setting runs trim the base game and leave the round itself alone. Spin-batch figures are 250,000 runs of twenty-five 20p spins, and the wagering figures are 100,000 attempts at playing those winnings through ten times at the same stake. The model says nothing reliable about the titles with ceilings of 10,000x and above.

Rules, dates and the 2020 warning about selling entry to a bonus feature are the Gambling Commission’s. Brand facts cover ownership, offer formats and published enforcement figures only; nothing here says that a named brand is running a particular promotion or carrying a particular game today. The offshore packages are described as their terms stood in October 2026, and a cashier can change them from one week to the next.
