Slot Details

The Big Bass Splash slot is played with 5 reels, 3 rows and 10 fixed paylines. You need 3 or more matching symbols from left to right, beginning on the leftmost reel and across any of the paylines to form a winning combination. With the monster truck symbol, 2 or more are required for a win. Like with most other online slot games, only the highest win per payline is awarded.

Catering to all pockets, you can play Big Bass Splash from as little as 10p per spin. The max bet ranges up to £250 with some UK casino sites limiting the max bet limit to £100, £50 or even £20. To change your bet, use the plus/minus buttons below the reels. Located in the UK? You won’t be able to use Autoplay or the Turbo/Quick Spin mode.

When it comes to returns, the Big Bass Splash RTP rate is 96.71%. A lot higher than the standard 96%, Pragmatic Play has produced 2 other RTP versions: 95.67% and 94.6%. Check with the game’s Paytable for the rate you’re playing with.

High volatility and ranked by the studio as 5/5, the hit frequency rate is 13.66%. This means a winning combination will land every 7.32 spins on average.

Lastly, the Big Bass Splash online slot can reward you with 5,000 times bet max wins. With bigger wins coming in the Free Spins feature, the max win probability is 1 in 3,086,876 spins. Winning 1,000 times your total bet or higher will occur once every 85,761 spins on average too.

Theme, Audio + Symbols

Released on the 23rd of June 2022, the Big Bass Splash slot is the fifth game in the Big Bass slot series. With an obvious fishing theme, it’s time again to pick up the fish rod and return to the shoreline. This time you head a canyon where the reels are set under the water.

With a Wild West influence, you’ll notice to banjo-inspired, upbeat soundtrack. On the reels, you will see colourful A, K, Q, J and 10 royals as well as standard ‘Big Bass’ symbols such as different-sized fish money, bait boxes, dragonflies, fishing rods and, oddly, a monster truck. The monster truck symbol pays the most with 5 across a payline awarding a 200 times bet payout.

As with other games in the series, there is a Fisherman Wild symbol. He, bearded and wearing a cowboy hat, substitutes for all symbols bar the Hooked Bass Scatter and appears on all reels during the Free Spins feature only. The latter triggers the free spins when 3 or more appear anywhere during a base game spin. Below you’ll find a list of payouts and functions for all symbols:

  • Q/J/10: 3, 4 or 5 = 0.2, 1 or 5 x bet
  • A/K: 3, 4 or 5 = 0.2, 2.5 or 10 x bet
  • Fish Money: 3, 4 or 5 = 1, 5 or 20 x bet
  • Dragonfly/Bait Box: 3, 4 or 5 = 2, 10 or 50 x bet
  • Fishing Rod: 3, 4 or 5 = 3, 15 or 100 x bet
  • Monster Truck: 2, 3, 4 or 5 = 0.5, 5, 20 or 200 x bet
  • Fisherman Wild: Substitutes for paying symbols
  • Hooked Bass Scatter: 3+ triggers Free Spins feature

Big Bass Splash Mobile

With Pragmatic Play creating all their slot games using HTML5 technology, Big Bass Splash is available to play on all devices including laptops, PCs, tablets, MACs and smartphones. The colourful graphics, cheery soundtrack and simple 5x3 reel layout make it perfect for playing at online mobile casinos.

Bonus Features

Whilst everything centres around the Free Spins feature, the Big Bass Splash slot comes with a total of 6 bonus features. In the free spins, there are plenty of extras which I go into in more detail below.

Free Spins

Triggering the Free Spins feature will require you landing 3 or more Hooked Bass Scatter symbols anywhere during a base game spin. The chances of this occurring is 1 every 113 spins on average (free spins hit frequency rate). Anyway, 3, 4 or 5 scatters will result in 10, 15 or 20 free spins respectively.  

Random features

If you only manage to land 2 scatters in the base game, the Respin feature can randomly activate. All reels with a scatter symbol will respin which gives you another opportunity to land an extra scatter symbol. There is also a randomly triggered Hook feature which can come into play with 2 scatters land. A fishing hook will pill up 1 of the reels to add another scatter to the reels.

Before you start playing, up to 5 modifiers are randomly awarded. You could get none too. Here is what they offer:

Modifier Description
More Fish More fish money symbols appear on the reels
More Fisherman Wilds Extra Fisherman Wilds appear on the reels
More Dynamite, Hooks + Bazookas Increased chance of triggering these bonus features
Start from Level 2 Start on level 2 (with a 2x multiplier)
2 Extra Free Spins 2 more free spins plus 2 more free spins on each retrigger

Once you’re in the free spins, bear in mind that the Fisherman Wild symbol can land on all 5 reels. When he does, all the fish money symbol values on the reels are collected and won. There’s also a series of random-triggered features to enjoy:

  • Bazooka feature: This can trigger if a Fisherman Wild symbol lands with no fish money symbols on the reels, Fish money symbols will then randomly appear which are then collected.
  • Dynamite feature: If fish money symbols land with no Fisherman Wilds, this feature adds Fisherman Wilds to the reels which then collects the fish money symbol values.
  • Hook feature: When fish money symbols land with no Fisherman Wilds, a hook pulls up a random reel to add a Fisherman Wild.

Finally, all Fisherman Wild symbols landing during the feature are collected. Collecting 4 will see you retrigger the feature with an extra 10 free spins awarded. With each retrigger, a multiplier applies to fish money symbols collected by Fisherman Wilds.

There are 4 levels with a total of 58 free spins to play in total. Also, a multiplier of up to 10x will be applied to fish money symbols collected. There is a progress bar at the top of the screen by the way but below is a table showing all the details:

Level Fisherman Wilds Collected Extra Free Spins Fish Money Multiplier
2 4 10-12 2x
3 8 in total 10-12 3x
4 12 in total 10-12 10x

Buy Free Spins

For players outside the UK, there is an optional Buy Free Spins feature. This allows you to buy your way into the Free Spins feature for 100 times your total bet. Randomly awarding 3, 4 or 5 scatters, the RTP rate remains the same (i.e. 96.71%).

Expert Verdict

Big Bass Splash slot OLBG rating banner

With so many Big Bass games, the Big Bass Splash slot has become one of the most popular in the series. Influenced by the Wild West which is evident in the Hillbilly soundtrack, the graphics are pretty good. I don’t know why Pragmatic Play decided to introduce a monster truck symbol though. Maybe it’s because rednecks go out on fishing trips in their trucks and beers and fishing equipment in tow.  

The gameplay centres around the Free Spins feature. Triggered in the traditional way (3+ scatters), there are a couple of randomly-triggered options when you land 2 scatters. I like the fact you can win up to 5 modifiers before the free spins begin which can set you up nicely once you’re in the feature.

You also have 3 randomly triggered features which may arise when no Fisherman Wilds and fish money symbols appear on the reels. They basically allow you to collect fish money values. That said, the key to winning big is by retriggering the feature and winning extra free spins and benefitting from a multiplier up to 10x on fish money symbol wins. From the screenshot above, you’ll see I did well when I retriggered the feature 3 times.

The levels and fish money multipliers are also present in Big Bass Bonanza but that slot offers 2,100 times bet max wins whereas Big Big Splash can reward you to the tune of 5,000 times your total bet. If it’s win potential you’re after, Big Bass Hold and Spinner Megaways is the clear winner with 20,000 times bet max wins up for grabs.

Want to reel in bigger catches? Push Gaming’s Razor Returns has a 96.55% RTP rate and 100,000 times bet max wins. Another good option is Nolimit City’s Ugliest Catch which offers 50,000 times bet payouts and a dirty take on the traditional fishing theme.
