Bigger Bass Bonanza Slot: Complete Review 2026

Bigger Bass Bonanza is the highly anticipated sequel to Pragmatic Play's enormously popular Big Bass Bonanza slot, and as the name suggests, everything about this fishing-themed adventure has been scaled up for an even more thrilling experience. Released on 16th September 2021, this slot takes players from the original lakeside setting to the neon-lit waters of Miami, Florida, delivering a vibrant visual upgrade whilst retaining the beloved mechanics that made its predecessor such a massive hit among slot enthusiasts. With a 5x4 grid layout offering 12 paylines, Bigger Bass Bonanza provides more opportunities to land winning combinations than the original 5x3 version. The game maintains an impressive RTP of 96.71% whilst cranking up the volatility to very high levels, promising those heart-pounding moments that experienced players crave. The maximum win potential has nearly doubled compared to the original, now offering a spectacular 4,000x your stake. Whether you are a fan of the original Big Bass Bonanza or discovering this fishing franchise for the first time, this sequel delivers enhanced gameplay with multipliers reaching up to 10x during the Free Spins feature, making it an essential title for any slot enthusiast seeking big win potential.

Theme and Graphics

Bigger Bass Bonanza transports players to a stunning Miami-inspired setting, complete with palm trees silhouetted against a vibrant night sky and the unmistakable glow of neon lights reflecting off the water. The visual upgrade from the original Big Bass Bonanza is immediately apparent, with Pragmatic Play opting for a more polished and atmospheric aesthetic that perfectly captures the excitement of night fishing in the Magic City. The reels are set underwater, providing a unique perspective as various fish symbols swim across your screen whilst the cityscape twinkles in the background.

The symbol design maintains the fishing theme established in the original game whilst benefiting from enhanced graphics and more detailed artwork. Lower-paying symbols consist of the classic royal card values from 10 through to Ace, each designed with a clean, readable style that does not distract from the action. The higher-paying symbols are where the theme truly comes alive, featuring beautifully rendered fishing equipment including a tackle box, fishing hooks, a fishing rod, and the premium fishing boat symbol that can trigger wins with just two matching symbols on a payline.

The colour palette is dominated by deep blues and purples of the underwater environment, contrasted brilliantly by the bright oranges and yellows of the fish symbols and the vivid neon accents from the Miami backdrop. The soundtrack deserves special mention, featuring an upbeat synthwave composition that perfectly complements the neon aesthetic and keeps the energy high during extended play sessions. Sound effects are crisp and satisfying, with each win accompanied by appropriate audio cues that enhance the overall gaming experience. The Fisherman character, who serves as the Wild symbol, is rendered with charming detail, complete with his fishing net ready to scoop up any valuable fish that swim into view.

Gameplay Mechanics

Bigger Bass Bonanza operates on a 5-reel, 4-row grid with 12 fixed paylines, representing an upgrade from the original game's 5x3 layout with 10 paylines. This expanded grid provides additional winning opportunities whilst maintaining the straightforward gameplay that made the series so accessible to players of all experience levels. Wins are formed by landing three or more matching symbols on a payline, starting from the leftmost reel, with the exception of the premium fishing boat symbol which pays out with just two matching symbols.

The betting range is impressively flexible, catering to both casual players and high rollers alike. The minimum stake is set at just £0.12 per spin, making it accessible for those who prefer to play conservatively, whilst the maximum bet reaches £240.00 for players seeking maximum excitement and win potential. This broad range ensures that Bigger Bass Bonanza can accommodate virtually any bankroll and playing style.

The hit frequency rate stands at approximately 12.11%, meaning players can expect to land a winning combination roughly once every 8.26 spins on average during base game play. However, it is important to note that due to the very high volatility, these wins can vary significantly in size, with many smaller wins punctuated by occasional larger payouts. The Free Spins feature, which is where the real excitement lies, triggers on average once every 121.84 spins.

Symbol values in the base game are structured to provide a balanced paytable. The royal card symbols (10, J, Q, K, A) all share the same return of 10x your total bet for a five-of-a-kind combination. Moving up to the themed symbols, the tackle box and fishing hook both pay 50x for five matching symbols, the fishing rod delivers 100x, and the premium fishing boat symbol offers the highest regular payout at 200x your stake for a complete payline. The fish symbols serve a dual purpose, acting both as regular paying symbols and as Money symbols carrying random cash values.

The Fisherman Wild symbol substitutes for all regular paying symbols, helping to complete winning combinations. However, his true value becomes apparent during the Free Spins feature, where his collection abilities and connection to the multiplier system can lead to truly spectacular wins. Understanding how these mechanics interact is crucial for appreciating the full potential of Bigger Bass Bonanza.

Bonus Features

The bonus features in Bigger Bass Bonanza represent the heart and soul of the game, with the Free Spins round offering exceptional win potential through a clever combination of Money symbol collection and progressive multipliers. Whilst the feature set may appear similar to the original Big Bass Bonanza at first glance, the upgraded mechanics deliver significantly enhanced winning possibilities.

Free Spins Feature

The Free Spins feature is triggered by landing three or more Hooked Bass Scatter symbols anywhere on the reels during base game play. The number of free spins awarded depends on how many Scatters you land: three Scatters award 10 free spins, four Scatters provide 15 free spins, and landing all five Scatters delivers a generous 20 free spins to begin the bonus round. This feature is the gateway to the game's biggest wins and introduces the Money symbol collection mechanic that can produce truly remarkable payouts.

During the Free Spins, the game dynamics shift significantly. Money symbols now appear on the reels displaying random cash values ranging from 2x up to an incredible 4,000x your total bet. These values are not paid out directly when they land; instead, they wait on the reels to be collected by the Fisherman Wild symbol. This creates a dynamic where every spin holds potential, as a well-timed Fisherman Wild appearance can scoop up multiple high-value Money symbols simultaneously.

Fisherman Wild and Collection Mechanic

The Fisherman Wild symbol is the star of the show during Free Spins, appearing on all five reels with the power to collect every Money symbol currently visible on the grid. When the Fisherman lands, he casts his net and gathers all Money symbol values, adding their combined worth to your winnings. This collection mechanic creates moments of genuine excitement, particularly when multiple high-value Money symbols are waiting to be caught.

The Fisherman also acts as a standard Wild symbol, substituting for regular paying symbols to help complete winning combinations. This dual functionality makes his appearance doubly valuable, potentially contributing to both line wins and Money symbol collections in a single spin.

Multiplier Progression System

Above the reels sits a progression meter that tracks your Fisherman Wild collections throughout the Free Spins feature. Every time a Fisherman Wild lands and collects Money symbols, the meter advances by one position. For every four Fisherman Wilds collected, players receive a retrigger bonus consisting of additional free spins and, crucially, an increase to the Money symbol multiplier.

The multiplier progression works as follows: upon the first retrigger (4 Fisherman Wilds collected), you receive 10 additional free spins and the multiplier increases to 2x. The second retrigger boosts the multiplier to 3x with another 10 free spins. Reaching the third retrigger level pushes the multiplier to an impressive 10x, dramatically amplifying the value of every Money symbol collection for the remainder of the feature. This progressive system means that extended Free Spins sessions with multiple retriggered spins can lead to extraordinary payouts.

Goldfish Symbol

Within the Free Spins feature, players may encounter the elusive Goldfish symbol, which represents the ultimate prize in Bigger Bass Bonanza. This special Money symbol carries a fixed value of 4,000x your total stake, and when collected by the Fisherman Wild with an active multiplier, the results can be absolutely massive. Landing a Goldfish whilst the 10x multiplier is active represents the pathway to the game's maximum win potential.

Random Bazooka Feature

An exciting random element during the Free Spins is the Bazooka feature, which can trigger when only a single Fisherman Wild appears on the reels. When activated, the Bazooka shoots additional Money symbols onto the reels, which are then immediately collected by the Fisherman. This feature adds an extra layer of excitement and unpredictability to the bonus round, occasionally transforming what might have been a modest collection into a substantial win.

RTP and Volatility Analysis

Bigger Bass Bonanza maintains the same generous Return to Player percentage as its predecessor, offering a theoretical RTP of 96.71% in its standard configuration. This places the slot comfortably above the industry average of approximately 96%, indicating fair return potential over extended play sessions. However, players should be aware that Pragmatic Play has released multiple RTP versions of this game, with some casinos offering reduced RTP variants at 95.67% or 94.62%. It is always advisable to check the game information at your chosen casino to confirm which version you are playing.

The volatility rating has been increased to very high (5 out of 5) compared to the medium-high volatility of the original Big Bass Bonanza. This shift has significant implications for gameplay experience and bankroll management. High volatility means that wins tend to be less frequent but larger when they do occur. Players can expect longer dry spells between significant payouts, punctuated by occasional impressive wins, particularly during the Free Spins feature.

Statistical analysis reveals some interesting insights into the game's behaviour. The probability of triggering the Free Spins feature is approximately 1 in 122 spins, making it a relatively rare but achievable event during most sessions. Once triggered, the feature's potential is substantial, though reaching the maximum win requires perfect alignment of high-value Money symbols and the 10x multiplier.

The maximum win probability is calculated at approximately 1 in 981,884 spins, highlighting just how rare achieving the full 4,000x potential truly is. This extreme rarity is typical of very high volatility slots and should inform players' expectations and bankroll planning. The game is designed to provide entertainment through frequent smaller wins whilst offering the tantalising possibility of life-changing payouts for the extraordinarily lucky.

For players accustomed to lower volatility games, Bigger Bass Bonanza requires a mental adjustment and appropriate bankroll management. Sessions can swing dramatically between profit and loss, and patience is essential when pursuing the bonus features. The reward for this patience is the potential for wins that simply are not possible in lower volatility titles.

Max Win Potential

The maximum win in Bigger Bass Bonanza stands at an impressive 4,000x your total stake, representing a near-doubling of the original Big Bass Bonanza's 2,100x maximum. At the highest bet level of £240, this translates to a theoretical maximum win of £960,000, though more typically players will be pursuing this potential at lower stake levels.

Achieving the maximum win requires a perfect storm of favourable conditions during the Free Spins feature. Players must first accumulate enough Fisherman Wild symbols to reach the third retrigger level, activating the 10x multiplier. With this multiplier active, landing the elusive Goldfish symbol worth 4,000x alongside other high-value Money symbols, all collected by a well-timed Fisherman Wild, can push the total payout to the maximum cap.

Whilst the 4,000x maximum may appear modest compared to some modern slots offering 10,000x or higher potential, it represents a substantial improvement over the original game and sits well within the range of what most players can realistically hope to achieve during particularly fortunate sessions. The progressive multiplier system means that even without reaching the absolute maximum, impressive wins in the thousands of times stake are regularly achievable during productive Free Spins rounds.

The mathematical distribution of wins in Bigger Bass Bonanza follows the typical pattern for very high volatility slots, with the majority of spins returning less than the stake, a significant portion returning between 1x and 50x, and rare but exciting instances producing wins of 100x and above. The Free Spins feature is where almost all significant wins occur, with the base game primarily serving to maintain player engagement whilst waiting for the bonus to trigger.

Mobile Compatibility

Bigger Bass Bonanza has been developed using HTML5 technology, ensuring seamless compatibility across all modern devices and platforms. Whether you prefer playing on desktop, tablet, or smartphone, the game delivers an identical experience with no compromise in visual quality or feature functionality. The interface automatically adapts to different screen sizes, with touch controls optimised for mobile play.

On mobile devices, the game loads quickly and runs smoothly even on mid-range smartphones. The larger 5x4 grid translates well to portrait orientation on phones, with symbols remaining clear and easily distinguishable. The control buttons are positioned intuitively for thumb access, and the spin button responds reliably to touch input.

The sound design translates excellently to mobile play, with the synthwave soundtrack and sound effects maintaining their quality through headphones or device speakers. Players can easily toggle sound on or off depending on their environment, making Bigger Bass Bonanza equally suitable for home play or gaming on the go. Battery consumption is reasonable for a modern video slot, allowing for extended mobile sessions without rapidly draining your device.

Expert Verdict

Bigger Bass Bonanza successfully delivers on its promise of being a bigger, better version of the beloved original. Pragmatic Play has expertly enhanced the formula without fundamentally altering what made Big Bass Bonanza such a phenomenon in the slot world. The expanded grid, doubled maximum win potential, and refined visual presentation combine to create a sequel that respects its heritage whilst offering meaningful improvements.

The progressive multiplier system during Free Spins is the standout feature, creating genuine excitement as players work towards the 10x multiplier level. The potential for massive wins during extended bonus rounds, particularly when high-value Money symbols align with active multipliers, provides the kind of adrenaline rush that keeps players returning to the reels.

However, the very high volatility is not for everyone. Players who prefer regular, modest wins will find the extended dry spells challenging, and the bankroll requirements for serious sessions are substantial. The relatively infrequent bonus triggers can test patience, though the potential rewards justify the wait for those willing to embrace the variance.

For fans of the original Big Bass Bonanza, this sequel is an essential play. For newcomers to the series, it represents an excellent entry point with superior graphics and enhanced win potential. The fishing theme may be well-worn territory in the slot world, but Pragmatic Play's execution here is exemplary.

Rating: 4.2 out of 5

Bigger Bass Bonanza earns its rating through exceptional production values, fair RTP, and genuinely exciting bonus mechanics. The deduction reflects the extreme volatility that limits appeal for casual players and the modest innovation over the original release. Nevertheless, for players who appreciate high-variance slots with substantial win potential, this remains one of the finest fishing-themed releases available.
