Big Bass Slot Series – Play Online for Real Money at Top UK Casinos

Big Bass slots are some of the most popular fishing-themed games you can play online for real money. With exciting bonus rounds and vibrant graphics, they’ve become a favorite at top UK casinos.

What is Big Bass? 

Big Bass is a slot series built around a simple idea — fishing. No fantasy worlds, no ancient temples. Just reels, symbols, and a calm atmosphere that feels familiar from the first spin. The games focus on light visuals, clear rules, and gameplay that doesn’t require a manual. 

Created by Pragmatic Play, Big Bass began with a single title — Big Bass Bonanza — and quickly found an audience. It offered something accessible. Players didn’t need to figure out complex features. They just spun the reels, looked for fish, and hoped the fisherman would show up during free spins to collect the prize. 

As our research has shown, over time, Big Bass became more than one game. It turned into a series. Variations appeared — with new mechanics, seasonal themes, and higher volatility for those who want a faster pace. Yet the appeal remains steady: casual play, strong visuals, and real chances to win. 

Big Bass Review: Features of the Popular Game Series 

The Big Bass games by Pragmatic Play are built around clarity, reward, and variety. Each game in the lineup shares a foundation — but every release introduces a different rhythm, structure, or visual focus. 

Structure of Reels and Paylines 

Most Big Bass titles stick to a 5-reel, 3-row format with 10 fixed paylines. This traditional setup ensures intuitive gameplay, where wins count from left to right and feature mechanics are easy to follow. In contrast, certain entries — like Big Bass Bonanza Megaways — expand the grid and introduce cascading reels with up to 46,656 ways to win. 

Volatility ranges from medium to very high, giving players the option to choose between steadier outcomes or high-risk sessions with bigger potential returns. The average Big Bass Bonanza RTP sits at 96.71%, though some variations may differ slightly depending on the edition. 

Bonus Rounds and Features 

The bonus rounds in the Big Bass slots are a key attraction — simple in concept but packed with potential. In nearly every version, landing three or more scatter symbols activates Big Bass Bonanza free spins, often starting at 10, 15, or 20 spins, depending on the number of scatters. 

During free spins, the fisherman wild becomes active. Whenever he lands alongside fish symbols, he collects their cash values and adds them to your win. In many titles, collecting four fishermen unlocks another retrigger — with added multipliers like 2x, 3x, or even 10x in the later stages. It’s a mechanic that builds tension and offers escalating rewards without overwhelming complexity. 

Some versions, like Big Bass Bonanza Splash, introduce pre-bonus modifiers — granting extra fishermen, more fish symbols, or boosted starting spins. In Big Bass Hold & Spinner, the bonus takes a different turn entirely, using sticky coins that trigger a respin sequence, where each new coin resets the counter and builds toward larger wins. 

Symbols Across the Series 

Although each game may include slight visual tweaks, the symbol set stays largely consistent. As our tests have shown, you will most often find on the reels: 

The symbols are designed to be easily recognizable and straightforward. Even first-time players will quickly understand the paytable and bonus triggers — and for many, that’s the appeal. 

The Popularity of Big Bass Slot in the UK 

Big Bass isn’t just another slot — it’s a UK favourite. The game’s fishing theme, simple rules, and casual tone appeal to a wide audience. It works equally well for newcomers and experienced players, whether on desktop or mobile.

The game feels light, fun, and familiar. And thanks to smooth mobile optimisation, you can cast your line anytime — whether you’re commuting, relaxing at home, or on a weekend getaway. 

Popular Big Bass Slot Versions 

The Big Bass series launched in 2020, when Pragmatic Play released the original Big Bass Bonanza. What started as a single fishing-themed slot quickly grew into a full franchise — with over ten versions available today across desktop and mobile casinos. Each new title builds on the last, offering tweaks in volatility, visuals, or bonus mechanics. Some stay close to the original formula. Others bring bold changes. 

Below, we’ve highlighted the most popular and innovative entries in the series — the ones that have stood out for UK players and beyond. 

Big Bass Bonanza 

The Big Bass Bonanza is where it all started. This slot quickly became a casino classic. It offers a clean layout, medium volatility, and a steady RTP of 96.71%. The free spins round with the fisherman wild catching cash-bearing fish remains its signature. Ideal for players who want straightforward fun without complex features. 

Big Bass Splash 

Compared to the previous version, Big Bass Splash raises the tempo. Before free spins start, random modifiers can trigger — such as extra wilds, more fish symbols, or more spins. The volatility is higher than the original, adding tension to every spin. The Big Bass Splash RTP remains at 96.71%, but the excitement level jumps. 

Big Bass Vegas Double Down Deluxe 

This is where things get intense. Launched in 2024, Big Bass Vegas Double Down Deluxe adds new modifiers, larger win potential, and very high volatility. With an RTP of 96.50%, it’s tailored for players looking for risk, speed, and the bright lights of a Vegas-style fishing adventure. When people type Big Bass Vegas, they’re after serious thrills. 

Big Bass Mission Fishin 

Here, you don’t just spin. You complete objectives. The Big Bass Mission Fishin introduces a task system layered on top of traditional gameplay. It’s built for those who enjoy progression and structured goals, while still keeping the same 5x3 grid and familiar mechanics. 

Big Bass Secrets of the Golden Lake 

More atmospheric and mysterious, this 2023 title plays on the theme of discovery. Hidden prizes, foggy lake visuals, and sound design give it a different pace. It’s not just about the bonus round — it's about what lies beneath. RTP holds at 96.07%, and volatility is high. 

Big Bass Halloween 2 

Released in late 2023, this seasonal edition swaps out fish for festive frights — think pumpkins, haunted boats, and eerie effects. The gameplay of Big Bass Halloween 2 sticks closely to the original Bonanza format, but with a fresh coat of Halloween. RTP: 96.71%, volatility: medium. 

Big Bass Hold & Spinner 

This 2022 release is remembered for a new mechanic, Hold & Win. Special coin symbols lock in place and launch a respin round with big win potential. It feels faster, sharper, and suited to players who prefer dynamic gameplay over traditional free spins. RTP: 96.07%.  

A year later, the company released an innovative linked slot, Big Bass Hold & Spinner Megaways. As Irina Cornides, COO at Pragmatic Play, noted: “The gameplay is supercharged by the Hold & Spinner feature and the star power of Megaways to create plenty of opportunities for players to reel in big prizes.” 

Big Bass Bonanza Megaways 

Launched in 2021, this version leverages the Megaways engine to create up to 46,656 ways to win. During the spins, the symbols cascade out, so there are no restrictions on the lines. With very high volatility and a strong RTP of 96.70%, it’s a favourite for experienced players chasing unpredictable results. 

Big Bass Floats My Boat 

This 2024 release brings a refreshing twist to the series, both visually and mechanically. This slot introduces animated boat scenes, dynamic weather effects, and a new bonus feature where players collect fuel tanks to extend the free spins session. The core gameplay remains tied to the classic fishing mechanic, but additional modifiers make each round feel more varied. 

Where to Play Big Bass Slots 

Big Bass slots are widely available across UK-facing online casinos, but not all platforms offer the same level of user experience, bonuses, or game variety. The best place to play Big Bass Bonanza is Paddy Power. With a dedicated focus on popular titles, reliable performance, and exclusive promotions, Paddy Power offers one of the most complete environments for fans of the series.  

Their version of Big Bass Splash slot is especially well-regarded, frequently highlighted by players for its seamless mobile integration and regular free spin offers. Newcomers will also be able to appreciate the slot with 100 free spins - you just need to make a first deposit of at least £100. 

Other top-rated platforms include: 

• PlayOJO – Known for its no-wagering policy. What you win, you keep. Ideal for players who value transparency and straightforward terms. 
• LeoVegas – Strong on mobile and often among the first to offer newly released Big Bass titles like Big Bass Vegas Double Down Deluxe. 
• MrQ – A casual, user-friendly site that excels in offering free spins, including regular promotions on Big Bass Bonanza. 

Wherever you decide to cast your line, make sure the casino holds a valid UKGC licence and check for available Big Bass Bonanza free spins — these often come as part of welcome packages or ongoing player rewards.
