Big Bass Bonanza started life in 2020 as Pragmatic Play’s answer to Fishin’ Frenzy — and promptly out-bred it. Thirty-eight official sister slots later, this is the fastest-growing family in UK casinos — a 39th, Big Bass Vegas 1000, is already announced for September 2026. If you're after slots like Big Bass Bonanza, here’s every boat in the fleet compared: Splash, Megaways, Bonanza 1000, Splash 1000 and the rest, with RTPs, max wins and release order.
Where to Play Big Bass Slots
Every Big Bass Bonanza version at a glance
All Reel Kingdom games, published through Pragmatic Play. Two things stand out against rival families: the RTPs hold remarkably steady at the strong end of the industry (operators can select lower versions, so always check your casino’s paytable), and the release cadence — nothing else in UK slots ships this often.
| Game | Released | RTP | Max win | Volatility |
|---|---|---|---|---|
| Bigger Bass Bonanza | 16 Sep 2021 | 96.71% | 4,000x | High |
| Big Bass Bonanza Megaways | 18 Nov 2021 | 96.70% | 4,000x | High |
| Big Bass Splash | 23 Jun 2022 | 96.71% | 5,000x | High |

| Hold & Spinner | 27 Mar 2023 | 96.07% | 10,000x | High |

RTP and max win confirmed directly against each game’s own listing on pragmaticplay.com — checked 6 July 2026. Reel Kingdom titles ship in multiple operator-selectable RTP versions (typically the default shown here, plus lower 95.x%/94.x% builds), which makes paytable-checking more important in this family than any other on this site.

Every Big Bass sister slot, reviewed
In release order, because with this family the chronology is the story — each boat fixes or escalates the one before it.
1. Bigger Bass Bonanza
Nine months after the original, the first sequel did the obvious thing well: a fourth row, twelve paylines, and more scatters in the pool, making the all-important free spins noticeably easier to reach. It’s the original with the friction sanded off — and for many regulars it quietly replaced the 2020 game as their default cast. Pragmatic’s own listing confirms a 96.71% RTP and a 4,000x max win, both matching the original’s strong default.

2. Big Bass Bonanza Megaways
November 2021’s entry licensed Big Time Gaming’s engine and let the reels breathe — up to 46,656 ways with a 96.70% published default. The fisherman still collects every cash fish on screen; there are simply far more screens for the fish to hide in. The family’s first proof it could wear other studios’ engines without losing its accent.

3. Big Bass Splash
June 2022, and the moment the family found its modern shape. Splash added a feature-buy menu, dynamite scatters, and a 5,000x ceiling at a 96.71% default — and became arguably the most-streamed slot in Britain for a year. If the original is the family’s birthplace, Splash is its capital city.

4. Big Bass: Keeping it Reel
The engineers’ favourite. October 2022’s entry changed one rule with outsized consequences: the fisherman-wild multipliers persist through the whole bonus instead of resetting, so every extra wild compounds on the last. Sessions swing harder, and the late-bonus maths can turn genuinely silly. Pragmatic’s own page confirms a 96.07% RTP — the lowest default in the family so far — against a 10,000x ceiling. The thinking angler’s Big Bass.

5. Big Bass Bonanza: Hold & Spinner
December 2022 grafted the hold-and-win format onto the franchise: land the money symbols, lock them, respin the rest. It plays closer to a Gold Blitz-style collector than a classic Big Bass, which is exactly why it earns its place — it catches the players the main line doesn’t.

6. Bigger Bass Blizzard — Christmas Catch
The family’s December tradition, and the best of its seasonal line. Blizzard reskins Bigger Bass in snow, adds festive money symbols, and returns to lobby front pages every winter like a migratory bird. Mechanically familiar; commercially unstoppable.
7. Big Bass Amazon Xtreme
March 2023 took the boat up-river: piranha symbols that devour the low pays (leaving richer reels behind) and a jungle take on the escalating-multiplier bonus. It’s the family’s most aggressive redesign of its own basics, and the entry critics tend to rate above its fame.

8. Big Bass Secrets of the Golden Lake
February 2024’s entry is the family in its baroque phase — golden fish, lake-spirit upgrades, and layer upon layer of collection mechanics on the familiar chassis. Gorgeous to look at, and a good test of whether you find the modern additions delicious or busy.

9. Big Bass Bonanza 1000
Pragmatic’s own launch release quotes Irina Cornides, the studio’s Chief Operating Officer: “Big Bass Bonanza 1000 combines two of Pragmatic Play’s most popular slots series, pairing everyone’s favourite fisherman with 1,000x max money symbols and wins of up to 20,000x.” Released 24 April 2025, it gave the original the “1000” treatment Pragmatic first applied to Gates of Olympus: same game on the surface, substantially wilder distribution underneath, with the top fish rescaled toward a 1,000x-per-symbol logic. It exists for one kind of player, says so honestly, and closes the loop — the family’s first game, rebuilt for the players its own success created.

10. Big Bass Splash 1000
Released 8 December 2025, this is the franchise’s current record holder and the natural sequel to both Splash and Bonanza 1000 at once — the “1000-series” treatment applied to the game that already had the biggest mainline ceiling. Pragmatic’s own launch release, again quoting COO Irina Cornides, states: “Our Big Bass collection and supercharged ‘1000’ series of slots are popular with players across all demographics. Big Bass Splash 1000 augments both with bonus game modifiers, enhanced multipliers of up to 1,000x, and a massive 25,000x max win.” RTP sits at 96.52% by Pragmatic’s own listing, Very high volatility, and that 25,000x cap is the highest published figure anywhere in the family — a full ten times the original 2020 game’s ceiling.
Close cousins outside the family
The bloodline runs backwards to Blueprint’s Fishin’ Frenzy — the 2014 game whose fisherman-collects-fish formula Reel Kingdom borrowed and industrialised. Games Global’s Fishin’ Pots of Gold and Blueprint’s own Big Catch Bass Fishing fish the same waters. The genre now has three dynasties; this one just publishes fastest.

The family DNA: the catch, upgraded
Reel Kingdom took Fishin’ Frenzy’s one perfect idea and added the two ingredients that define this family.
The fisherman wild that collects
As in the elder game, fish land carrying cash values and the fisherman gathers every one on screen. The upgrade: here he’s a wild, so he pays his way even when the nets are empty.
The retrigger ladder
The family’s signature. Collect enough fisherman wilds during the bonus and you don’t just retrigger — you climb: +10 spins with a 2x multiplier on the fish, then 3x, then 10x. Every Big Bass session is really a question of how far up this ladder you get, and every sequel remixes exactly this climb (Keeping it Reel makes it persistent, Amazon Xtreme feeds it piranhas, 1000 steepens the whole staircase).
The escalation business model
The third ingredient isn’t a mechanic, it’s a schedule: seasonal editions every October and December, a crossover most summers, and a heavier-calibre remix every year or so. No other family treats its own catalogue as a release calendar quite like this.

The maths: strong defaults with an asterisk
At its published default the family is among the best-paying mainstream slots in the UK — 96.71% on the original and Splash beats almost everything in the Rainbow Riches or Age of the Gods stables. The asterisk: Pragmatic ships operator-selectable RTP versions, and plenty of UK sites run the 95% or 94% builds. Same game, same fish, quietly different deal — the in-game info screen tells you which version you’re holding, and in this family that check is worth thirty seconds every single time.
Expected average cost per 100 spins at the 96.71% default:
| Stake | 100 spins staked | Expected average cost (3.29%) |
|---|---|---|
| 10p | £10 | £0.33 |
| £1 | £100 | £3.29 |
| £5 | £500 | £16.45 |
✓ Calculated from the published 96.71% default RTP — checked 3 July 2026
High volatility means real sessions live far from these averages — the ladder pays rarely and hard. Budget like it’s fishing: most days, the water wins. Our responsible gambling tools are the life jacket.
History and legacy
In December 2020, Reel Kingdom — a small studio publishing through Pragmatic Play — released what looked like a straightforward tribute to Blueprint’s six-year-old Fishin’ Frenzy. What happened next reshaped UK slots: the imitation out-shipped, out-marketed and eventually out-grew the original. Bigger Bass within a year; Megaways within two; then Splash, which streaming culture adopted as a house game and turned into a phenomenon.
The family has since released at a pace no rival matches — seasonal editions on a fixed calendar, sports crossovers, engine borrowings, and now the 1000-series remixes. Where Fishin’ Frenzy aged into an institution, Big Bass turned itself into a production line.
Why this franchise still matters
Because it proved the fastest route to owning a genre is to publish relentlessly inside it. Big Bass took someone else’s mechanic and built the industry’s most disciplined release machine around it — a new boat for every season, every audience and every volatility appetite. Slot families used to be back-catalogues; this one behaves like a live service. The rest of the industry has spent five years learning to copy the copier.
Beyond the reels: seasons, sports and jackpot waters
The seasonal calendar
Halloween in October, Blizzard or Christmas Bash in December — the family’s seasonal editions are as reliable as supermarket mince pies, and lobbies promote them the same way. No other slot franchise has annualised itself so completely.
The sports crossovers
Day at the Races, Boxing Bonus Round, Football Bonanza: whenever Britain watches sport, the fisherman sells a tie-in. They’re light remixes, but they mark how far the brand has drifted from being merely a slot toward being a mascot.
Jackpot Bonanza
Several titles ship in Jackpot Bonanza builds with progressive tiers attached — the family’s answer to Blueprint’s Jackpot King editions of its rival. Same trade as ever: a slice of RTP for a ticket to a shared pot.
Who makes it, and is it licensed?
Reel Kingdom is a subsidiary studio publishing exclusively through Pragmatic Play, which is why every Big Bass title carries Pragmatic branding in casino lobbies and runs under Pragmatic’s own regulatory approvals rather than a separate licence of its own. Pragmatic Play (Gibraltar) Limited holds UK Gambling Commission account 56015, confirmed via the Commission’s public register.
What players say
Big Bass discourse splits by generation of player. Streamers and their audiences treat Splash and the 1000-series as canon and rate the family for its ceiling-chasing bonuses; longer-memoried players grumble that it’s Fishin’ Frenzy with a marketing department. Two complaints recur with real substance: the operator-selectable RTP versions (players discovering their casino runs the 94% build feel legitimately stung) and sequel fatigue — even fans struggle to say what separates boat twelve from boat fifteen. Nobody, notably, complains about the core loop. The ladder still lands.
The biggest Big Bass wins
The ceilings tell the family’s story in numbers: 2,100x on the 2020 original, 5,000x on Splash two years later, 20,000x on 2025’s Bonanza 1000, and 25,000x — the current family record — on December 2025’s Splash 1000. At Splash’s cap, a £1 spin pays £5,000 — and the retrigger ladder means the biggest recorded community wins overwhelmingly come from deep bonus runs at 10x, not lucky base hits. This is also the most-streamed slot family in Britain, so its biggest wins are unusually well documented; here’s a real Splash session for the flavour:

The best Big Bass Bonanza slot for your bankroll
| If you want… | Play | Why |
|---|---|---|
| The definitive modern entry | Big Bass Splash | The family at its peak, 5,000x on tap |
| The gentlest introduction | The 2020 original | Cleanest version of the loop |
| Compounding chaos | Keeping it Reel | Multipliers that never reset |
| Maximum ways | Megaways | 46,656 of them at 96.70% |
| A different format entirely | Hold & Spinner | Respins instead of spins |
| The deep end | Bonanza 1000 or Splash 1000 | The rebalanced heavy-calibre builds |
| December | Bigger Bass Blizzard | The ritual, refined |
Mechanic contrasts outside Big Bass Bonanza
Vikings Go, Templar Tumble and Action Bank do not share Big Bass Bonanza’s fishing lineage. They are contrast picks for sticky-wild progression, maximum-volatility mystery reveals and a pub-style bank bonus. Big Bass remains the collection-free-spins choice, where fisherman wilds gather the visible fish values.
| Series | Choose them if… | Choose Big Bass Bonanza if… |
|---|---|---|
| Vikings Go (Yggdrasil Gaming) | You'd rather have medium-high volatility, closer to The Vikings Go Berzerk sticky-wild feature | A high-volatility session centred on Fisherman wilds collect all fish values suits you better |
| Templar Tumble (Relax Gaming) | A maximum (5/5)-volatility session built around Mystery Reveal appeals more | You're after Reel Kingdom's take instead — Fisherman wilds collect all fish values |
| Action Bank (Barcrest — now part of Light & Wonder) | A medium-volatility session built around The Big Bank Bonus appeals more | You'd rather have high volatility, built around Fisherman wilds collect all fish values |

Our verdict on the original
Sister Slots score: 8/10 — the borrowed idea that built an empire.
| Features | 8/10 — the retrigger ladder is the genre’s best single upgrade |
|---|---|
| Win potential | 7/10 — 2,100x is honest for the era, dwarfed by its own children |
| Design | 7/10 — clean, warm, built to be understood at a glance |
| Playability | 9/10 — ten lines, 10p, and a bonus everyone chases the same way |
Play the original if you want the loop at its purest and a strong default RTP. Pick a sister slot if you’ve outgrown it — that’s what the fleet is for, and the fleet knows it.
