Which Big Bass Slot Is Best? Every Game Ranked and Compared

There are now over 30 Big Bass slots available as of 2026, and working out which one deserves your time is no small task. The series launched in December 2020 with Big Bass Bonanza, developed by Reel Kingdom and distributed by Pragmatic Play, and has since expanded into four distinct sub-series spanning original titles, supercharged 1000 editions, Megaways variants, and jackpot integrations. This guide ranks every Big Bass slot game based on RTP, max win potential, feature depth, and replay value, giving you a clear answer to which Big Bass game pays out the most and which suits your style of play. Whether you are brand new to the series or have played every release, this breakdown covers the full picture.

The Big Bass Series at a Glance

• Developer: Reel Kingdom
• Distributor: Pragmatic Play
• First Release: December 2020 (Big Bass Bonanza)
• Total Games in Series: 30+ titles
• Typical RTP Range: 94.60% to 96.71% (varies by operator configuration)
• Typical Volatility: High (4/5 or 5/5 on Pragmatic Play’s internal scale)
• Shared Mechanics: Fisherman Wild symbol, Money Fish value collection, Free Spins as the primary bonus feature, collect-trail upgrades in later titles

Every Big Bass title shares the same fishing theme and core collect mechanic, but the differences between entries are significant. Some offer max wins of 2,100x your stake, while others reach 25,000x. Understanding these distinctions is the entire point of this guide, and it starts with knowing what ties the series together.

What Every Big Bass Game Has in Common

Despite the growing number of titles, the Big Bass series shares a recognisable DNA that makes moving between games feel familiar. The standard layout is a 5×3 grid with 10 fixed paylines, though certain entries like the Megaways versions and the 3 Reeler break from this template entirely.

The central mechanic across the series is the Fisherman Wild. During Free Spins, a Fisherman symbol lands on the reels and collects the values displayed on all visible Money Fish symbols on that same spin. This creates a concentrated payout moment that can stack up significantly when multiple Money Fish appear alongside the Fisherman. It is this mechanic that gives every Big Bass game its characteristic rhythm: relatively quiet base game sessions punctuated by high-potential Free Spins rounds.

Later entries in the series introduced a collect-trail upgrade system, where the Fisherman can level up during Free Spins to gain multipliers (2x, 3x, or even 10x) applied to collected Money Fish values. Some titles also added extra Fishermen, Hold and Spin mechanics, and dynamic reel modifiers. But at their core, all Big Bass games revolve around triggering Free Spins and landing the right combination of Fisherman Wilds and Money Fish.

The Four Big Bass Sub-Series, Explained

One of the most useful ways to navigate the Big Bass catalogue is to group the games by sub-series. Each branch targets a slightly different player preference.

Original Line

This is where it all started. Titles include Big Bass Bonanza, Bigger Bass Bonanza, Big Bass Splash, Bigger Bass Splash, Big Bass Amazon Xtreme, Big Bass Day at the Races, and several seasonal editions. These games generally feature 5×3 grids, 10 paylines, and max wins ranging from 2,100x to 5,000x stake. They suit players who want the classic Big Bass experience without additional complexity.

1000 Series

The 1000 series takes existing fan favourites and supercharges them. Big Bass Bonanza 1000 and Big Bass Splash 1000 are the headline entries, offering max wins of 20,000x and 25,000x respectively. These remakes retain the original game structure but add enhanced multiplier trails and significantly higher win ceilings, making them the go-to choice for players chasing the biggest possible payouts.

Megaways Line

Big Bass Bonanza Megaways and Big Bass Hold & Spinner Megaways swap the fixed 10-payline structure for up to 46,656 ways to win. The variable reel sizes on each spin create a different feel to the standard games, and the Hold & Spinner variant adds a respins mechanic on top. These are for players who enjoy the unpredictability of the Megaways engine combined with the familiar Big Bass collect feature.

Jackpot Bonanza Line

Titles like Big Bass Surf’s Up and Big Bass It’s a Whopper integrate jackpot features into the Big Bass formula. These games connect to progressive or fixed jackpot pools, adding an extra layer of potential reward. If you enjoy jackpot slot games, this sub-series bridges two popular slot formats in a single package.

The Complete List: Every Big Bass Slot Compared

The table below covers every Big Bass slot released to date, sorted by release date from oldest to newest. RTP figures reflect the highest available configuration, though operators may run lower RTP versions. Always check the information tab within the game itself before playing.

Note: RTP values shown reflect the highest published configuration from Pragmatic Play. The version available at your chosen operator may differ. Always verify within the game’s information tab.

Our Ranking Methodology

Ranking over 30 slots from a single series requires a consistent framework. Every Big Bass game in our top 10 was assessed across four factors:

1. Max Win Potential: The theoretical maximum payout expressed as a multiple of the stake. Higher ceilings reflect greater upside during bonus rounds.
2. RTP (Highest Available Version): The return to player percentage in its most favourable configuration. A higher RTP means a lower theoretical house edge over time.
3. Feature Depth and Bonus Variety: Games with multiple Fishermen, collect trails, multiplier upgrades, or hybrid mechanics score higher than straightforward single-feature titles.
4. Replay Value and Player Engagement: How well the game holds up over multiple sessions, considering theme variety, visual polish, and community reception among UK players.

UK availability is also a factor. Under UKGC rules, the Bonus Buy feature is not available to players in the United Kingdom. Titles that rely heavily on Bonus Buy as their primary appeal are noted but not penalised, since all games still function through natural Free Spins triggers.

The Big Bass Series Ranked: Top 10

#1 Big Bass Bonanza 1000

Released in January 2024, Big Bass Bonanza 1000 takes the original game’s formula and amplifies it dramatically. The max win jumps to 20,000x stake, thanks to a supercharged multiplier trail that can push the Fisherman’s collect value up to 1000x. RTP sits at 96.08% in its highest configuration, and volatility is rated 5/5, the highest on Pragmatic Play’s scale.

The game retains the familiar 5×3 grid and 10 paylines but adds escalating multiplier tiers during Free Spins that the original never offered. Each Fisherman catch can grow exponentially as the trail progresses, creating a snowball effect that accounts for those headline max win figures. For players asking which Big Bass game pays out the most in a single hit, this is the standout answer on paper.

Verdict: The best Big Bass slot game for players who want the original’s simplicity combined with genuine max win firepower.

#2 Big Bass Hold & Spinner Megaways

This March 2024 release merges two popular mechanics: the Megaways engine (up to 46,656 ways to win) and a Hold and Spin respin feature layered on top of the standard Fisherman collect. RTP is 96.07% and the max win reaches 10,000x, with volatility at 5/5.

What sets this apart from Big Bass Bonanza Megaways is the addition of the Hold and Spin round, which creates a secondary feature within Free Spins. Money Fish can lock in place and respin, giving more chances to fill the grid with value symbols before the Fisherman sweeps them up. The variable reel sizes on every spin mean payline potential shifts constantly, keeping sessions unpredictable.

Verdict: The strongest Megaways entry in the series, blending collect mechanics with respin tension for players who enjoy a layered feature set.

#3 Big Bass Splash

Big Bass Splash, released in June 2022, is widely regarded as the point where the series truly found its stride. With an RTP of 96.71% and a max win of 5,000x, it introduced multiple Fishermen during Free Spins for the first time. Up to four Fishermen can appear on the reels simultaneously, each collecting visible Money Fish values independently.

The extra lives mechanic was another series first. Collecting enough Fishermen during a round can extend the Free Spins feature, giving more opportunities for value accumulation. Volatility is 4/5, making it slightly more approachable than the 1000 series entries while still offering meaningful win potential. Among online slots from Pragmatic Play, this remains one of the most popular titles in the UK.

Verdict: The fan favourite for good reason, balancing accessibility, feature innovation, and a strong max win ceiling.

#4 Big Bass Bonanza

The one that started it all. Released in December 2020, Big Bass Bonanza offers the highest RTP in the series at 96.71% and a max win of 2,100x. Volatility is rated 4/5. The mechanics are stripped back to essentials: trigger Free Spins, land Fisherman Wilds, collect Money Fish values.

There are no multiplier trails, no multiple Fishermen, and no Hold and Spin rounds. This simplicity is the entire appeal. For anyone asking which Big Bass game has the highest RTP, the original shares the top spot with several other titles at 96.71%, but its straightforward design makes that favourable house edge particularly accessible. It is the ideal starting point for new players and remains a genuine classic within the Reel Kingdom catalogue.

Verdict: The cleanest, simplest Big Bass experience with the joint-highest RTP in the series, perfect for first-timers.

#5 Big Bass Splash 1000

The newest entry in the 1000 series arrived in December 2024 and holds the record for the highest max win across all Big Bass games at 25,000x stake. It takes the multi-fisherman mechanics of Big Bass Splash and applies the supercharged 1000 treatment, with multiplier trails that can escalate to extraordinary levels.

RTP is 96.08% with volatility at 5/5. The combination of multiple Fishermen (each with their own multiplier progression) and the 1000-series ceiling creates the most volatile and theoretically rewarding Big Bass game available. Sessions can be extremely dry, but the bonus rounds carry the highest upside of any title in the franchise.

Verdict: The absolute ceiling for max win potential in the Big Bass series, built for players comfortable with extreme volatility.

#6 Big Bass Amazon Xtreme

Released in May 2024, this jungle-themed entry swaps the traditional fishing lake for the Amazon river and replaces standard bass with piranha Money Fish. RTP is 96.71% and the max win sits at 5,000x with 4/5 volatility.

Beyond the visual refresh, Amazon Xtreme features an expanded collect mechanic with tiered piranha values and environmental modifiers during Free Spins that can boost the Fisherman’s effectiveness. The theme change alone gives it strong replay value for players who have logged hundreds of spins on the lake-themed originals.

Verdict: A strong mid-series entry that combines the proven collect formula with a genuinely fresh setting and solid feature depth.

#7 Big Bass Halloween

This September 2023 seasonal release proves that themed reskins can offer more than just new visuals. Big Bass Halloween carries a 96.71% RTP, a 4,000x max win, and 4/5 volatility. The Fisherman is reimagined with a spooky twist, and the Money Fish take on Halloween forms with adjusted value distributions.

The mechanics build on the Bigger Bass Bonanza template with upgraded Fisherman multiplier trails, but the Halloween presentation gives the entire package a distinct identity. It tends to see a surge in popularity each autumn and has carved out a niche as the strongest seasonal Big Bass title.

Verdict: The best seasonal Big Bass game, with genuine mechanical substance behind the themed visuals.

#8 Big Bass Bonanza Megaways

The first Megaways entry in the series launched in March 2022 with up to 46,656 ways to win. RTP is 96.07% and the max win reaches 4,000x at 4/5 volatility. It translates the core Fisherman collect mechanic onto the Megaways engine, where the number of symbols on each reel varies between 2 and 6 per spin.

While the Hold & Spinner Megaways version has since surpassed it in feature depth, this original Megaways entry remains a solid choice for players who want the variable-ways format without the additional complexity of respin mechanics. The base game generates more frequent small wins than the standard 10-payline games, though the bonus round remains the primary source of meaningful payouts.

Verdict: A clean Megaways adaptation that introduced the series to a new format, now slightly overshadowed by its successor but still worth playing.

#9 Big Bass Day at the Races

Released in July 2024, this crossover title brings horse racing theming to the Big Bass framework. The Fisherman is replaced by a jockey character, and the Money Fish become racing-themed value symbols. RTP is 96.71%, max win is 4,000x, and volatility sits at 4/5.

The racing theme is more than cosmetic. A race-based progression during Free Spins determines the Fisherman’s multiplier level, adding a visual narrative to the collect mechanic that most Big Bass games lack. It is a niche entry, but the thematic crossover works surprisingly well and gives the game a distinct personality within the catalogue.

Verdict: The most creative theme crossover in the series, pairing the collect mechanic with a racing progression that adds genuine variety.

#10 Big Bass Trophy Catch

The newest Big Bass slot at the time of writing, Trophy Catch launched in April 2026 with a headline feature: three distinct Fishermen, each with unique multiplier traits and trophy targets. RTP is 96.08%, max win is 5,000x, and volatility is rated 4/5.

The three-fisherman mechanic creates a dynamic where each Fisherman contributes differently to the overall Free Spins payout. One may specialise in high multipliers, another in collection range, and the third in extra spins. Achieving all three trophy targets unlocks a final bonus round. As the latest release, it represents the current evolution of the series and suggests where future Big Bass titles may head.

Verdict: A promising new entry with the deepest Fisherman variation yet, though it needs more time to establish its position among players.

Best Big Bass Slot by Player Type

Not every Big Bass game suits every player. Here are targeted recommendations based on what you are looking for:

• Best for New Players: Big Bass Bonanza. The simplest mechanics in the series, the joint-highest RTP at 96.71%, and a clean introduction to how the Fisherman collect system works.
• Best for Max Win Hunters: Big Bass Splash 1000. The 25,000x ceiling is the highest in the entire franchise, backed by multi-fisherman multiplier trails that can compound dramatically.
• Best for Megaways Fans: Big Bass Hold & Spinner Megaways. Combines 46,656 ways to win with a Hold and Spin respin layer, offering the deepest Megaways experience in the series.
• Best for Casual Sessions: Big Bass Bonanza 3 Reeler. A compact 3-reel format designed for shorter play sessions with a lower max win ceiling but quicker feature triggers.
• Best for Seasonal Play: Big Bass Halloween or Christmas Big Bass Bash. Both offer themed versions of proven mechanics with seasonal presentation that adds variety.
• Best for Fans of the Original: Bigger Bass Bonanza. Takes the original game’s structure and adds the multiplier trail, feeling like a natural upgrade rather than a reinvention.

A Note on RTP and Volatility

Most Big Bass games are published in two or three RTP configurations. The most common tiers are 96.71%, 95.50%, and 94.60%. The version you play depends entirely on which configuration your operator runs. At Funky Jackpot, you can check which RTP version is active by opening the game’s information tab or paytable before spinning. This is worth doing every time, as the difference between 96.71% and 94.60% represents a meaningful shift in the theoretical house edge over extended sessions.

All Big Bass titles carry high volatility ratings, either 4/5 or 5/5 on Pragmatic Play’s internal scale. In practical terms, this means you should expect longer stretches between bonus triggers, with the majority of significant wins concentrated within Free Spins rounds rather than the base game. The 1000 series entries (rated 5/5) are the most volatile, producing the longest dry spells but also the highest potential payouts when the bonus does land.

It is also worth knowing that the Bonus Buy feature, which allows players to pay a premium to trigger Free Spins instantly, is not available to UK players. This is a UKGC regulation that applies across all licensed operators. All Big Bass games at a UK casino must be played through natural spin-triggered features only.
