Big Bass Splash Slot Review
Big Bass Splash isn’t the first in the series – that title belongs to Big Bass Bonanza. Still, this sequel has become one of the most well-known, even with over 25 other slots, crash games, and instant win games in the franchise.
Since its release in 2022, the Big Bass Splash slot has carved out a loyal fanbase, popping up across many of the UK’s top online casinos and even forming part of their promotions.
So why has it caught on? For starters, it adds a few welcome tweaks to the usual format without straying too far from what made the original popular. These include randomly triggered modifiers before the bonus round, slicker animations, and a more modern look overall. It’s familiar but sharper, and most importantly, it’s suitable for novice players as well as slot veterans.
The Appeal of Big Bass Splash: Why Players Love It
Big Bass Splash doesn’t try to reinvent the wheel, but it gets a lot right. These features are a big part of its ongoing appeal:
- Pre-Bonus Modifiers: Random boosters like extra fish, dynamite, and playing in an upgraded level make gameplay unpredictable before free spins even begin.
- Playable on Any Budget: With permitted bets ranging between 10p and £250 per spin, the Big Bass Splash casino game is suitable for casual players and high rollers alike.
- Collect-and-Upgrade Bonus: The iconic fisherman returns to reel in fish and level up your round, boosting money symbol payouts throughout the bonus.
- Clean, Crisp Design: No clutter or chaos, just bold visuals and smooth gameplay that work well across desktop and mobile.
- Above-Average RTP: The Big Bass Splash slot RTP sits at 96.71%, which is on the higher end for most slot games in the UK.
🤔 Did You Know? The slot return to player (RTP) percentage can vary depending on the casino. Developers often release multiple RTP versions of the same game, and it’s up to the operator to choose which one to offer. Some casinos opt for the higher setting while others may use a lower one, such as 94% or even less.
Is Big Bass Splash Easy Slot to Play?
Yes, it’s not a particularly complicated slot at all. As with most of the games in this series, you should picks things up fairly easily after a small time spent playing the game.
How to Play Big Bass Splash Slot Game
This slot’s gameplay is quite simple, which is part of its charm. Whether you're new to online slots or just fancy a change, the controls are easy to get the hang of. Here’s how to get started:
Step 1: Set Your Stake
Click the ‘+’ or ‘-‘ buttons beside the spin icon to adjust your total bet per spin. You can adjust the ‘Coins Per Line’, the ‘Coin Value’, or, to keep things simple, just the ‘Total Bet’.Step 2: Spin the Reels
Hit the spin button once you’re happy with your stake. The reels will activate and then stop in sequence.Step 3: Watch Out for Any Payouts
Once the reels have come to a complete stop, any winning combinations in view will be automatically identified. Payouts are instantly transferred to your account. If a bonus feature is triggered, this will play out right after any payouts.Step 4: Consider the Autoplay Function
If tapping spin every few seconds feels like effort, click the ‘Autoplay’ button to set up multiple automatic spins. You can also activate ‘Turbo Spin’ or ‘Quick Spin’ for shorter rounds.
🤔 Did You Know? If you’re playing the Big Bass Splash demo or real money version at a UK-licensed casino, you won’t see the ‘Autoplay’ function. This option has been removed following the new slot rules published by the UK Gambling Commission (UKGC).
Understanding Big Bass Splash Payouts
Winning combinations are formed by landing matching symbols on adjacent reels from left to right, starting from the first reel. The game uses a fixed set of 10 paylines across its five-reel, three-row setup, and only the highest win per line is paid. Symbol values vary, with premium icons like the monster truck and fishing rod offering higher payouts, while standard card symbols cover the lower end.
The following table outlines the prizes paid by the 10 payout symbols:
Payout Symbol | 2 Matches | 3 Matches | 4 Matches | 5 Matches |
Monster Truck | 0.5x | 5x | 20x | 200x |
Fishing Rod | – | 3x | 15x | 100x |
Dragonfly | – | 2x | 10x | 50x |
Tackle Box | – | 2x | 10x | 50x |
Fish | – | 1x | 5x | 20x |
A | – | 0.2x | 2.5x | 10x |
K | – | 0.2x | 2.5x | 10x |
Q | – | 0.2x | 1x | 5x |
J | – | 0.2x | 1x | 5x |
10 | – | 0.2x | 1x | 5x |
Fish symbols serve a dual purpose in this slot game. During the base and bonus rounds, they can form standard winning combinations and pay out according to the paytable. In addition, during free spins, they can award the cash prize displayed on them.
Bonus Features in Big Bass Splash
Pragmatic Play’s Big Bass Splash casino game offers a handful of features that can kick in before and during the bonus round. It doesn’t flood the reels, but the few extras it does include are well worth paying attention to. You can even enhance your experience by playing the game using no wager free spins or other enticing bonuses.
The slot’s main event is the free spins feature, triggered by landing three or more scatter symbols. Depending on how many scatters you hit, you’ll get 10, 15, or 20 free spins. But before the bonus even begins, the game might throw in up to five modifiers:
- More Fish: Increases the number of money-carrying fish symbols during free spins, which boosts your chances of a decent haul.
- More Fishermen: Adds extra wilds to the bonus round, making it easier to collect fish and level up.
- More Dynamites, Hooks & Bazookas: Raises the odds of those fun little animations that toss fish on the reels or drag in extra scatters.
- Start from Level 2: Skips the initial bonus stage and begins free spins with a 2x multiplier already active.
- +2 Spins: Adds two extra spins at the start and awards two more each time you retrigger the bonus.
Big Bass Splash RTP & Volatility
If you’ve ever wondered how often a slot pays out and how much it might give when it does, this is the section that explains it. RTP stands for Return to Player, and this slot has a solid rate of 96.71%, which is a touch above the industry norm.
The game is also known for its high volatility. That means you’re more likely to experience longer dry spells, but with the potential for bigger payouts when things go your way. Think of it like waiting for a big wave forming across multiple spins – you won’t catch small rewards often, but when you do, they can be significant.
This slot has also been certified for fairness by top testing labs like Gaming Labs International (GLI) and BMM Testlabs. These independent bodies ensure the RTP and volatility are accurate and that the game meets UK regulatory standards.
Big Bass Splash Free Spins
This is the feature most players are angling for. It’s where the game swaps steady spins for chaotic bursts of potential, complete with collectors, multipliers, and the odd explosive rescue. We’ve already covered the initial bonus modifiers earlier in this Big Bass Splash slot review, but there’s plenty more going on once you’re in.
During the bonus, any fisherman wild symbol that lands will collect the values from all visible fish money symbols on the screen. These amounts can be anything from 2x to 5,000x your total bet.
What makes the feature more interesting is its progressive mechanic. Every fourth wild you collect retriggers the bonus, giving you 10 more spins and bumping up the multiplier for fish values:
- Level 2 = 2x multiplier
- Level 3 = 3x multiplier
- Level 4 = 10x multiplier
You can only retrigger free spins up to three times, and after that, the bonus ends naturally when your spins run out. However, if you’re in search of no deposit free spins, you’ll find several casino sites offering them to UK players.
There are also a few random modifiers that can help you out mid-bonus. If you have a fisherman but no fish, dynamite might drop a few money symbols onto the reels. Similarly, if you have fish but no fisherman, a hook might swing in and drag one onto the screen.
However, if the spin is a complete bust, a bazooka might wipe most of the screen, except any fishermen, and respin the whole lot.
Bonus Buy Option
For those who don’t fancy waiting around, this online slot includes an optional bonus buy feature. For 100x your current stake, you can jump straight into the free spins round without needing to land three scatters naturally. The number of triggering scatters is still random, but you’ll bypass the base game entirely.
As always, this option isn’t available if you’re playing Big Bass Splash on a UK site due to regulations. You can, however, play it at offshore casino sites, since these are not governed by the UKGC.

Top Tips on How to Win on Big Bass Splash
While no strategy guarantees a slot game win, our Big Bass Splash tips should help you play smarter and avoid common mistakes.
- Start with a Budget: Set a fixed amount before you play and stop playing as soon as you’ve spent it. This helps you enjoy the game while gambling responsibly and avoiding chasing losses.
- Time Your Sessions Around Bonus Potential: Since most of the game’s payout potential lies in the free spins round, consider walking away if it’s not triggering after about 20 or so spins. Playing in shorter sessions helps avoid long dry spells and keeps your gameplay focused on when the game is actually doing something.
- Play at a Comfortable Stake: Don’t go big hoping for fast wins. A lower, steady stake keeps you in the game longer, giving more chances to hit bonus features.
- Check the RTP at Your Casino: Some sites offer lower RTP versions of this and other slot games. If possible, play the game on sites that unlock its highest payout percentage of 96.71%.
- Don’t Rely on Autoplay: Autoplay is convenient, but it’s easier to lose track of your spending. Manual spins keep you more engaged and aware of your balance.
Our Verdict on Big Bass Splash
The Big Bass Splash slot is one of those sequels that undoubtedly deserves praise. We’ve found that it’s instantly recognisable by fans of the series, but offers just enough extra features to make it distinct. It doesn’t try to dazzle with over-the-top features or convoluted mechanics, and that’s part of the charm.
Moreover, its wide betting limits and mobile compatibility make it a solid pick that holds up well against other popular slots in the UK.
