Big Bass Bonanza

By Becky M. | Updated 17 July 2026

Big Bass Bonanza, developed by Pragmatic Play and Reel Kingdom, is a highly volatile video slot with an RTP of 96.71%. Boasting features such as wilds, scatters, and free spins, it promises rewarding gameplay and up to 2,100x the bet.

Pragmatic Play has made significant progress in recent years, as evidenced by the quality and number of monthly slots landing at UK online casinos.

This developer releases at least five new titles every month. Each game is innovative, immersive, and packed with unique features and exciting gameplay.

The Big Bass Bonanza slot is one of Pragmatic Play’s most popular slots, inspired by the traditional sport of fishing. Developed with Reel Kingdom, the Big Bass Bonanza slot is set to be the first of many in this series.

Big Bass Bonanza Technical Features

Big Bass Bonanza is played on a 5-reel, 3-row layout with 10 fixed paylines. Winning combinations are formed by landing three or more matching symbols from left to right, starting on the leftmost reel.

The slot is available on desktop and mobile devices, with stakes ranging from 10p to £250 per spin. Big Bass Bonanza has an RTP of up to 96.71% and medium to high volatility, although lower RTP versions are also available at some online casinos.

The maximum win is 2,100x the bet. The biggest payouts come from the Free Spins feature. Fisherman Wilds collect cash values from fish symbols and retrigger bonuses to unlock increasing multipliers.

Design & Symbols

Big Bass Bonanza takes players beneath the water’s surface, where transparent blue reels sit against an underwater backdrop filled with bubbles and aquatic scenery. The cartoon-style artwork gives the slot a light-hearted feel, while the upbeat soundtrack complements the relaxed fishing theme without distracting from the gameplay.

The lower-paying symbols are the colourful A, K, Q, J, 10 and 9 royals. The premium symbols reflect the fishing theme and include fish, tackle boxes, dragonflies and fishing rods. The fishing float is the highest-paying symbol, awarding 200x the bet for five of a kind.

The Fisherman Wild only appears during the Free Spins feature. It substitutes for all regular paying symbols except the Scatter. The Fisherman Wild’s main role is to collect the cash values attached to fish symbols whenever they land. Multiple Fisherman symbols can land on the same spin, with each one collecting the full value of every fish symbol on the reels.

The cheerful fisherman has become one of the most recognisable characters in modern online slots, appearing throughout the Big Bass Bonanza series in many guises.

Big Bass Bonanza Bonus Features

The slot includes a collect game similar to Fishin’ Frenzy, along with the free spins bonus round. Let’s take a more in-depth look at the Big Bass Bonanza bonus features.

You’ll need between 3 and 5 scatters anywhere on the reels to trigger the free spins. Once triggered, the number of triggering scatters determines the free spins you’ll play.

3 scatters = 10 free spins

4 scatters = 15 free spins

5 scatters = 20 free spins

Remember I spoke of the fish symbols? These all have cash values and now crop up in this bonus feature. If the fisherman symbol appears on the reels, he collects all the cash values from the fish symbols. He uses his fishing rod to do this. In a nutshell, the more fish symbols in view, the bigger your prize. The fisherman also has another role. He is a wild symbol and replaces all symbols except the scatter. This leads to much bigger wins.

Things ramp up if you land more than one fisherman on a single spin. If this happens, all the fishermen collect all the fish cash values individually. For instance, if you land two fishermen on a spin, and the fish’s value adds up to £30, you’ll get £60.

Each time a wild lands, it is collected in a meter located above the reels. After collecting four wilds in the meter, the free spins bonus round retriggers, and 10 spins are awarded. Any fish symbols in view are multiplied thanks to the active multiplier.

To win the possible 10x multiplier, you need to collect up to 12 wilds. You can also get a total of 50 free spins. There’s a chance to retrigger the feature up to three times; after that, no more retriggers are possible.

The Big Bass Bonanza Series

The success of Big Bass Bonanza turned a standalone slot into one of Pragmatic Play’s most recognisable franchises. Since its release in 2020, the developer has expanded the series with numerous sequels, each introducing new mechanics while keeping the fisherman collect feature at the heart of the gameplay.

Bigger Bass Bonanza was the first sequel, increasing the maximum win and adding more volatility for players chasing larger payouts. Pragmatic Play then released Big Bass Bonanza Megaways, combining the original collect mechanic with the popular Megaways system to deliver thousands of ways to win.

Seasonal releases soon followed, including Christmas Big Bass Bonanza and Big Bass Halloween, while games such as Big Bass Splash, Big Bass Amazon Xtreme, Big Bass Hold & Spinner and Big Bass Return to the Races introduced fresh settings and additional bonus features without straying too far from the formula that made the original so successful.

Despite the growing number of sequels, the original Big Bass Bonanza remains the benchmark for the series. Its straightforward gameplay, memorable fisherman mechanic and accessible bonus feature continue to attract both new and experienced slot players, making it one of Pragmatic Play’s most enduring releases.

Many well-known software developers have upgraded their popular slots with the Megaways mechanic. This mechanic allows up to 44,696 ways to win. Pragmatic Play incorporated the Megaways mechanic and has since released Big Bass Bonanza Megaways. It comes with the same top prize of 4000x, and the collect feature and wilds are present as with the first two slots in the series.

Christmas Big Bass Bonanza

In 2021, Pragmatic released Christmas Big Bass Bonanza just in time for the festive season. Once more, the slot looks very similar to the first two. The only difference is the festive details in the visuals. All the fish wear Christmas hats, the royal symbols are covered in snow, and various Christmas-themed icons appear on the reels. If festive-themed slots are your thing, then Christmas Big Bass Bonanza will be up your street. All the games in the Big Bass series are fun. They offer entertaining gameplay and chances to win big prizes. The festive game is sure to do the same.

After the successful release of the original Big Bass Bonanza video slot, it was a no-brainer. Pragmatic would release a series of Big Bass slots. Although these are all similar to the original, they are unique due to a new mechanic, theme, and top prize payouts.

Why Big Bass Bonanza Is Still One of the Most Popular Online Slots

Few online slots have enjoyed the longevity of Big Bass Bonanza. Released in 2020, it remains one of the most recognisable titles from Pragmatic Play and continues to feature prominently at online casinos worldwide.

One reason for its longevity is its widespread use in UK online casino promotions. Many operators include the Big Bass Bonanza slot and other slots in the series as part of welcome offers, free spins promotions, slot tournaments, and network campaigns. Because the gameplay is familiar and appeals to a broad audience, casino operators know the games will attract new and returning players.

The Big Bass series benefits from Pragmatic Play’s promotional network. Games are frequently selected for campaigns such as Drops & Wins, in which participating casinos award cash prizes with regular gameplay. These types of promotions help keep Big Bass Bonanza front and centre long after the original release and introduce the series to new audiences throughout the year.

Another factor behind its popularity is the steady expansion of the franchise. Rather than moving on after the original’s success, Pragmatic Play has released numerous sequels featuring new themes and mechanics while retaining the fisherman collect feature that made the original so memorable. This helped build a recognisable brand, with players often returning to compare the latest release with the original.

Perhaps the biggest measure of Big Bass Bonanza’s success is its influence on the wider slot industry. The collect mechanic wasn’t new when the game launched, but its success helped popularise the format and inspired a wave of fishing-themed slots from other developers. Even today, new releases are regularly compared with Big Bass Bonanza, highlighting its status as one of the defining online slots of the modern era.

For many players, the original remains the benchmark. Its straightforward mechanics, familiar bonus feature and enduring popularity have helped it outlast countless new releases, making Big Bass Bonanza one of the few modern slots that can genuinely be described as a classic.
