Big Bass Slots: 13 Fishing Games Rated by Price and Top Prize, and Where to Play Them

Big Bass slots in one minute: the picks and where to play

• Cheapest to play. Four titles share the top published default, 96.71%: Big Bass Splash, Bigger Bass Bonanza, the 2020 original and its Christmas edition. Of those, Big Bass Splash states the largest ceiling, 5,000x.
• Biggest top prize. Big Bass Splash 1000 states 25,000x at 96.52%, and Big Bass Bonanza 1000 states 20,000x at 96.51%. Each costs 23p or 24p more per evening than the 96.71% group.
• Pay the 96.07% price only for a feature you want. Five titles released from October 2022 to March 2024 add things such as a coin bonus or sticky multipliers, and cost 77p more per 1,200-spin evening at 10p.
• Where to play. One route is an offshore-licensed casino with a deposit package from £20 or €20; search each lobby for the title. Wherever you play, read the rules screen, because the original also runs at 95.67% or 94.6%.
• Your stake decides how long the evening lasts. On the Bass-style model, 16.3% of £10 sessions at 10p were still playing after 1,200 spins; at 50p, only 19.4% got past the first 100.

If you only remember one line: pick from the 96.71% group unless a later title has a feature you actually want, and keep the stake small enough that the evening is an evening.

Before you pick a Big Bass title: a two-minute check

Seven lines decide what a Big Bass session costs and what it can pay. Run through them before the first spin; most take seconds.

Of the seven, the third is the one players skip and the one that costs most. A 94.6% setting on the original adds £2.53 to an evening at 10p, more than three times the 77p that separates the series’ cheapest and dearest published defaults. Read the rules screen as routinely as you would check a price tag.

13 Big Bass titles, rated

The ratings sort titles first by price group, because the RTP sets the cost of every spin, and then by stated top prize, because inside each group the RTPs differ by 0.02 of a point at most, about 3p over an evening at 10p. “Evening” means 1,200 spins at 10p, £120 staked: about two hours at a relaxed pace of one spin every six seconds, or 50 minutes at the legal maximum.

Group one: the 96.71% titles (and one at 96.70%)

Group two: the 1000 editions, 96.51% to 96.53%

Group three: the 96.07% titles

Not rated: Big Bass Hold & Spinner Megaways (28 August 2023), which publishes neither an RTP nor a top prize in the sources used here and offers up to 147,456 ways. Pragmatic called it the franchise’s “landmark tenth release”, though it is only the ninth in this list, so at least one earlier title is missing from this list.

The ratings answer two different questions, and they point at different games. If you want the lowest price per spin, rank 1 is the answer. If you want the largest possible prize, rank 6 is. The rest of the page helps you decide which question is yours.

How often the free-games round turns up over an evening

Every Big Bass game saves its biggest moments for the free spins, so it helps to know how long the wait usually is. On the Bass-style model the round comes once every 175 spins on average, but averages hide streaks: the chance of seeing it at least once grows quickly at first and then slowly.

Chance of at least one round in n spins = 1 − (174 ÷ 175) to the power n

Two planning lessons. First, a short session is a coin toss for the round: more than half of 100-spin runs never see it, and that is the normal outcome, not bad luck. Second, the spins that do reach the round still have to pay for the wait. Even the full average gap, 175 spins, costs 58p at 10p and £1.44 at 25p before the round has paid a penny, which is why a modest stake and a long horizon suit these games better than a big stake and a short one.

The model’s round is the same on every setting, so a lower build does not delay it; it only thins the base-game wins you collect while you wait. Real titles with bigger ceilings, from the 10,000x games to Splash 1000, may space their best rounds further apart, and Pragmatic does not publish how often any of them land.

How the series’ price and ceiling moved

Lay the 14 releases end to end and two lines appear. The price drifted down and partly back; the ceiling climbed almost without pause.

Three price steps, in plain money. From December 2020 to June 2022 the titles published 96.71% (the Megaways one 96.70%): £3.95 an evening at 10p. Five of the six games from October 2022 to March 2024 published 96.07%: £4.72 an evening, so the house keeps 3.93p of every pound staked instead of 3.29p, nearly a fifth more. The 1000 editions of 2025 and 2026 came back to 96.51% to 96.53%: £4.16 to £4.19, which is 21p to 24p dearer than the first group and 53p to 56p cheaper than the middle one. Pragmatic’s published figures give no reason for any of the steps.

Evening cost = 1,200 spins × £0.10 × (1 − RTP); at 96.07%, £120 × 0.0393 = £4.72

At bigger stakes the gaps grow in proportion. At 25p a spin, £300 of stakes, an evening costs £9.87 at 96.71%, £10.44 at 96.52% and £11.79 at 96.07%. On the original at its 94.6% setting it would cost £16.20, more than any published default in the series. Meanwhile the stated top prize went from 2,100x on the first game to 25,000x on Big Bass Splash 1000, 11.9 times as large, at a published RTP that ended slightly lower.

Big Bass against the other fishing games

Pragmatic is not the only studio with a fisherman. Blueprint Gaming publishes Fishin’ Frenzy at 96.12% with settings down to 90% (94%, 93% and 92% in between), and lists Fishin’ Frenzy The Big Catch Gold Spins as a UK-only release at 95%, with settings down to 90% and a 2,500x top prize. Priced over the same 1,200-spin evening at 10p:

At their defaults, the cheapest Big Bass titles undercut both Blueprint games. At their lowest settings the gap widens sharply: 90% costs three times the 96.71% evening. Whichever fisherman you pick, the rules screen is still the deciding check.

Price your own evening

The calculator opens on the dearest group in the series: 10p a spin, 600 spins an hour for two hours, on a 96.07% title. That is the 1,200-spin evening used throughout this page, which by this page’s arithmetic costs about £4.72 on average. Change the stake, the pace, the hours and the RTP to match your plan; type 96.71 for the cheapest group, the 1000 edition’s figure for a remake, or whatever the rules screen shows if it is lower.

Treat the answer as the price of the evening, not a forecast of it. The session section below shows the spread around that price: most £10 budgets at 10p ran out before 1,200 spins, and roughly one in seven finished ahead.

What each title adds to the fishing formula

The original sets the pattern. On a 5×3 grid, fish symbols carry money values of up to 2,000x the stake; landing three scatters starts 10 free spins, four start 15 and five start 20; in the free spins the fisherman wild collects the fish, and every fourth wild retriggers the round with a multiplier of 2x, then 3x, then 10x. Pragmatic classes it as medium-high volatility with a 2,100x maximum. Every later title changes one or two of those dials.

• A bigger grid. Bigger Bass Bonanza stretches the reels to four rows. During its free spins a Goldfish scatter is worth 4,000x, which is also the game’s stated top prize.
• Ways instead of lines. The Megaways edition of the original drops fixed lines for a changing count of ways, lets fish reach 4,000x, and is the one title Pragmatic calls high volatility. The Hold & Spinner Megaways version goes up to 147,456 ways.
• Boosts before the free spins. Splash keeps the classic ten-line 5×3 grid and adds a lottery before the round: up to five random modifiers can be dealt before the free games start.
• Better wilds. Keeping it Reel adds golden wilds; Big Bass Vegas 1000 brings red and blue fisherman wilds.
• A second bonus. Hold & Spinner bolts a second feature onto the formula: coins that lock in place and respin, separate from the free games.
• Multipliers. Amazon Xtreme puts fish money up to 1,000x together with a random multiplier of up to 40x; Floats My Boat uses sticky multipliers of up to 50x.
• The 1000 editions. All three let a single fish carry up to 1,000x the stake (from 2x upwards on the original’s remake), and two of them state ceilings, 20,000x and 25,000x.
• More free spins. Vegas 1000 adds five free spins at every scatter level compared with the original: 15 for three scatters instead of 10, and up to 25 for five.

Day at the Races and the Christmas edition publish no extra mechanic in the sources used here. For how the same remake pattern runs through the studio’s other lines, from Gates of Olympus to Sweet Bonanza, see the Pragmatic Play slots guide.

How long £10 lasts: stake first, setting second

Price tells you what an evening costs on average. It does not tell you how long the money lasts, which is what most players actually notice. So each line below is 100,000 simulated £10 sessions on the Bass-style model, which matches Big Bass Bonanza’s published 96.71% RTP and 2,100x maximum, pays something on about 23.5% of spins and reaches its free-games round about once in 175. Each session played up to 1,200 spins and stopped early only when it could not cover the next spin.

Start with the stake. £10 covers 100 spins at 10p, 50 at 20p and 20 at 50p before any win comes back, and the table follows that arithmetic closely. At 50p, four sessions in five were over inside the first 100 spins, about four minutes at the fastest legal pace. At 10p, more than half were still going after 300 spins and one in six after the full 1,200.

Then the setting. The 94.6% build trims two to four points off every checkpoint from 300 spins (57.7% to 53.8% at 300 spins, 16.3% to 14.1% at 1,200) and the share ending ahead from 13.4% to 11.6%. It matters, but it matters less than the stake: going from 10p to 20p on the best setting costs far more session than going from the best setting to the worst at 10p.

Notice too what a bigger stake does not do. It does not raise your chances of walking away ahead: 13.4% of 10p sessions ended above their starting £10, against 6.9% at 20p and 2.7% at 50p, because the faster sessions mostly ended long before 1,200 spins. A small stake is the planner’s friend here. It buys time, and time is what the round needs to turn up.

Which Big Bass game for which evening

The Splash 1000 premium: £4.18 against £3.95 is 23p. The promotional-spins row is priced in full, setting by setting, on the 20 spins on Big Bass Bonanza page, and the free spins by slot guide shows how a game’s volatility changes what a spin offer is worth.

Big Bass on the high street: what the Entain deal tells you

Entain, owner of Ladbrokes and Coral, announced on 25 November 2025 that the fishing games, naming Big Bass Bonanza, Big Bass Splash and Big Bass Hold & Spinner among them, would go into more than 2,700 of those brands’ betting shops. No major operator had put the series into its shops before. The same announcement made two claims about online play: Entain said each title is a consistent member of its top 20 at both brands, and called Big Bass Splash its best-performing UK online slot of 2025.

Read those claims for what they are. They describe how much the games are played at two brands, not how much they pay back; Entain did not say what “top-performing” measured, and Big Bass Splash’s published default, 96.71%, is exactly what three other titles in the series publish. Popularity is a good reason to try a game and no reason to stake more on it.

The deal also says something about the brands. Ladbrokes and Coral are Entain’s high-street bookmakers, and Entain runs them alongside a large bingo and casino estate, Party Poker, Sportingbet, PartyCasino, Foxy Bingo and Gala Bingo among them, on shared accounts. A welcome claimed at one of those names usually counts for the others. Entain’s largest Commission fine or settlement on record is £17m, from 2022.

Where to play Big Bass slots online

An offshore deposit package is one option, with its terms in full view. As of October 2026 this part of the market held licences from Anjouan, Costa Rica or Curaçao; no Commission licence covers it, Gamstop does not reach it, and the licensing jurisdiction is named in the terms. A package out here starts at £20 or €20 per deposit, the wagering reads 35x to 40x, the spins (150 to 500 a package) arrive in stages, and the terms warn that documents come before the first withdrawal. Nothing in the terms says which games a casino carries, so search the lobby for the exact Big Bass title you want, then open its rules before you stake.

At casinos licensed in Great Britain, the brand facts on record point to where different kinds of player tend to look:

• Shops you can walk into. Four names have premises on British streets: Betfred, Admiral Casino (owned by Novomatic), Genting Casino and Grosvenor Casinos (Rank). A brand with a shop on your high street is quick to verify and slow to disappear. Betfred’s largest Commission penalty was £3.25m, in 2023.
• A long online record. At evoke, 888 Casino has been online since 1997, with 777 Casino and 888sport beside it; William Hill joined the group in 2022, and its £19.2m penalty of 2023 is the group’s largest.
• Winnings without wagering. Neither PlayOJO, run by SkillOnNet, nor MrQ, run by Lindar Media, attaches wagering to a bonus, so whatever a promotion pays on a Big Bass title is cash.
• Sport first. bet365, which also owns Heart Bingo, is a sportsbook first and bases its casino welcomes on a deposit; its largest penalty was £582,120 in 2024.

None of that tells you the setting a given casino runs on the original. Only the game’s rules page does, which is why the highest-payout casinos guide starts every check there.

The UK rules every Big Bass session runs under

To the regulator a fishing game is simply another online slot, so at a licensed casino it comes with the same five controls. Each changes how a session feels, and most change what it can cost.

1. Stakes are capped. Since 9 April 2025 a spin may cost no more than £5 once you are 25; since 21 May 2025, no more than £2 for anyone aged 18 to 24. At the fastest legal pace, 24 spins a minute, that still means £4.72 a minute of average cost at £5 on a 96.07% title, or £1.58 a minute at £2 on a 96.71% one.
2. Spins are slowed down. Since 31 October 2021 no spin may take less than 2.5 seconds, autoplay and turbo buttons are gone, and your net position and time played stay on screen throughout.
3. The bonus round cannot be bought. Pragmatic’s release notes mention buying the feature “in select markets”; British players are not among them, following the Commission’s warning to operators in January 2020.
4. You are verified before you play. That has applied since 7 May 2019 even to free demo play: no licensed site may let you try a fishing game, money or no money, before it knows who you are.
5. Withdrawals stay withdrawn. A withdrawal request at a licensed site has been final since 31 October 2021: the site may not invite you to reverse it and play on. Bonus wagering has been capped at 10x since 19 January 2026.

A planner’s reading: the rules set the speed limit, not the destination. Decide your own stake and stop time first; the rules only make sure you have time to notice them.

Big Bass at an offshore casino: what changes

An offshore casino holds its licence outside Britain, so none of the five rules above binds it. A bonus-buy button may appear, stakes can run past £5, spins can go faster than one every 2.5 seconds, and there is no on-screen running total, no Gamstop link and no UK complaints route. Wagering on their packages runs at 35x to 40x rather than the UK’s 10x cap.

Ten minutes at £10 a spin and full pace: 240 spins = £2,400 staked; at 96.07%, an average cost of £94.32

That figure is what speed and stake together can do to the same fishing game once the British limits are gone. If you do play offshore, write down the limits a licensed site would have imposed, a stake, a time and a total, and keep to them.

Four Big Bass myths that cost money

• “Newer means better value.” The opposite happened in the middle of the series: the titles of 2022 to 2024 dropped to 96.07%, and the 1000 editions came back only to 96.51% to 96.53%.
• “A 1000 edition pays ten times as much.” What grows almost tenfold is the ceiling, 20,000x against 2,100x for the original’s remake. The return does not grow at all: at 96.51% against 96.71%, the remake costs fractionally more per spin.
• “The most popular title must pay best.” Big Bass Splash leads Entain’s online figures and publishes 96.71%, the same as three other titles.
• “The free spins are due.” Every spin is independent. On the Bass-style model, with a round about once in 175 spins, 100 spins give a 43.6% chance of seeing it, so more than half of 100-spin runs never do.

Walk away, too, if a site that calls itself British-licensed shows any of these: a button to buy the feature or speed up the reels, a stake above £5, wagering above 10x on a fishing-game offer, a crypto cashier, or a footer with no licence details.

Keeping the fishing trip short

Big Bass games are built around waiting for the round, and waiting is where sessions stretch. Plan the trip before you leave: a stake, a stop time and a total. Fix the total when the casino asks you for a deposit limit, which licensed sites have had to do for new customers since 31 October 2025, and let the on-screen timer police the stop time.

If the round lands early, treat it as the end of the session rather than a reason to stay; if it never lands, the table above says that is normal, not a debt the game owes you. A time-out rests one account. Gamstop rests all of them, and since 31 March 2020 no licensed online operator has been allowed to stay outside it. The safer gambling page lists the tools, and the National Gambling Helpline takes free calls on 0808 8020 133, 24 hours a day.

Where the ratings come from

Titles, announcement dates, published RTPs, stated top prizes, volatility labels and mechanics are Pragmatic Play’s published figures from its game pages and press releases, checked in October 2026; the original’s medium-high volatility class and its 95.67% and 94.6% settings come from the same verified game facts. Where Pragmatic states no figure, the tables say “not stated” rather than estimating one. Entain’s statements are from its announcement of 25 November 2025.

Costs are exact averages: spins × stake × (1 − RTP). An evening is 1,200 spins at 10p (£120 staked); the 25p figures use £300. Ceilings in pounds multiply the stated maximum by the stake. The session table comes from the bankroll runs of this site’s simulation library on the Bass-style model: 100,000 sessions per line, each starting with £10 at a fixed stake of 10p, 20p or 50p, played for up to 1,200 spins and stopped early only when the balance could not cover the next spin; the 94.6% line lowers the base game and keeps the round unchanged. The model matches Big Bass Bonanza’s published RTP and its 2,100x ceiling, wins on 23.5% of spins and averages one round per 175 spins. The real pay table is not public, so the model’s results describe that shape, not the real game or any casino, and no model here stands in for the later titles’ bigger ceilings.

Round odds use 1 − (174 ÷ 175) raised to the number of spins. UK rules are the Gambling Commission’s, with dates as given above. For bonus terms around these games, the welcome bonus guides apply the same arithmetic to matches and spins.
