Big Bass Bonanza™ Slot Overview

If you can’t imagine a more perfect day than relaxing by a lake with a fishing rod in hand, hoping to land a big catch, then you’ll absolutely love Pragmatic Play’s Big Bass Bonanza™ series. This iconic collection reunites no less than seven video slots with a maritime theme, featuring the same happy-go-lucky fisherman character. Whether he is out at sea or on holiday, his lure never misses!

Today, for our online slot reviews page, we’ll analyse the classic Big Bass Bonanza™, the first launch of the series that set the mood and general frame for the following sequels. Released on 3 December 2020, Big Bass Bonanza™ has a retro structure of five reels, three rows, and 10 paylines.

Developed in collaboration with Reel Kingdom studio (joining forces proved to be an inspired choice for both companies), this game enjoyed massive success not long after the official release, and it’s still wildly popular today.

This fun title invites players to take a deep dive underwater with our bearded protagonist, hoping for the green fish to bite and reward random money values! The slot has an estimated RTP score of 96.71%, which is not too shabby for a peaceful fishing adventure.

Based on Pragmatic Play’s custom ranking system for variance, this title received a 4/5, meaning it’s quite volatile, but less so than the other sequels, such as Bigger Bass Bonanza™ (5/5).

Triggering the Free Spins Triggering the Free Spins

There is a one in 113 chance of triggering free spins — this hit frequency is once again quite good, especially for a mid-high volatility title.

In terms of features, we are seeing a lot of originality from both studios —aside from Wilds and Scatters, the game introduces us to special money symbols to boost our wins. We also have a Free Spins bonus round, where the maximum win of the slot — 2,100x your stake — can be achieved. The betting range is very flexible, in tune with Pragmatic Play’s usual recipe of 0.1 (min) and 250 (max).

So, without further ado, let’s get that hook ready and take a closer look with our Big Bass Bonanza™ slot review!

Big Bass Bonanza™ Features

A classic in terms of reel layout and extras, Big Bass Bonanza™ doesn’t appear to make a splash at first. Like a slow day out on the boat waiting for the fish to bite, the base game is quite dull and uneventful; no Wild symbols fall and there are no win reactions, either. Even more annoyingly, we have a tacky, cartoonish soundtrack to keep us company until we trigger the bonus game!

Once we are in the ring, though, things really pick up speed, as free spins complete with multipliers, Wild substitutions, and instant cash prizes await!

Money Symbols

Big Bass Bonanza™ has three types of special symbols: Wilds, Scatters, and special money symbols, shaped like green fish. The latter can fall on the reels at any time during the base game or free spins, and when they do, they will be accompanied by a random money value.

Free Spins

As there is no Buy Pass offered, in order to trigger the Free Spins feature through regular play, you need to land at least three Scatter symbols in any position. The Scatter appears on all reels, and is shaped like a fish in a hook, with the word ‘Scatter’ embedded below.

Depending on the number of triggering Scatters, you’ll be granted a different number of extra spins, like so:

  • Three fish Scatter symbols – 10 free spins
  • Four fish Scatter symbols – 15 free spins
  • Five fish Scatter symbols – 20 free spins

Wild symbols will only fall during the Free Spins feature (the fisherman). Wilds can replace any other regular paying icon, aside from the Scatter. In addition, if the fisherman Wild lands at the same time as the fish money symbols, he will collect all the cash values listed on the screen for the player.

Wild symbols also get collected on a metre, located on top of the main reels.

Big Bass Bonanza Free Spins 2

If you manage to collect at least four wild symbols, you can re-trigger the free spins feature. This will result in extra spins, with a progressive win multiplier added on top, as such:

  • First re-trigger – 10 extra spins, with a 2x win multiplier
  • Second re-trigger – 10 extra spins, with a 3x win multiplier
  • Third re-trigger – 10 extra spins, with a 10x win multiplier

The multiplier values only apply to the re-triggered free spins, and only three re-triggers are possible in total. Lastly, if only a single fisherman Wild symbol lands at the end of a free spin, fish money symbols appear on the reels in random positions.

Big Bass Bonanza™ RTP & Volatility

Big Bass Bonanza™ has an estimated RTP score of 96.71%, which is slightly above average, so the return on investment can be quite good over a longer game session. Because it received a 4/5 on Pragmatic Play’s volatility scale, the game can be ranked as a medium-high variance title.

Some online casinos host this game in a lower RTP mode of 95.67%, so don’t forget to check the slot description before proceeding.

Symbols & Paytable

Our boat trip is embellished by a wide range of maritime symbols, such as fishing rods, bait, and multiple types of fish.

Pragmatic Play also sprinkled in some original special symbols aside from the well-known Scatters and Wilds. The game’s paytable is very clear, as it’s accompanied by explanations and visuals:

  • Low-Value Symbols – card suits 10, J, Q, K and A, with each paying up to 10x your stake for five of a kind
  • Green Fish Money Symbols – pay up to 20x your stake for five of a kind
  • Tackle Box – pays up to 50x your stake for a matching five
  • Blue Dragonfly – pays up to 50x your stake for five of a kind
  • Fishing Rod – premium icon, pays up to 100x your stake for five of the same symbol
  • Green & Blue Fishing Float – premium icon, pays up to 200x your stake for five of a kind
  • Fisherman – Wild symbol, only appears during free spins, replaces regular paying icons
  • Fish Scatter Symbol – 3+ trigger the Free Spins feature

Theme, Graphics, Soundtrack & User Experience

A trademark of many Pragmatic Play slots is the insertion of cartoonish graphics and colourful visuals. This can also be seen in other titles with vastly different themes, like The Dog House Megaways™ or Bomb Bonanza.

Because it’s a fishing-themed video slot, the developer opted for simplicity in its presentation: the main reels are filled with handy tools for a big catch, such as rods or bait, and they are submerged in the ocean, alongside underwater vegetation and corals.

The later versions of the Big Bass Bonanza™ slot phenomenon were improved with realistic waves and water bubbles, but for a first attempt, it still manages to create some form of atmosphere. The cheerful soundtrack accompanying our spins also instils a feeling of relaxation in the player, similar to the real-life experience of fishing.

Stakes & Betting Range

Both high rollers and low-stakes players can explore these calm waters to their heart’s content, as the betting range is very flexible, starting at only 0.1 per spin and going up to a generous 250, making it perfect for both a top low-stake slot and a high-stake slot.

The maximum win can be obtained during the bonus game, and it’s capped at 2,100x your stake, which is disappointingly low. You can only obtain a significant win in real money if you play with the maximum betting range.

Big Bass Bonanza™ Mobile Play

Given that it was released quite recently, in the year 2020, Pragmatic Play utilised the latest HTML5/Java Script technologies when developing this title. As a result, you can try it out straight from your mobile or web browser in insta-play format. The slot is compatible with smartphones running on Android/iOS software, tablets, and desktop devices.

Although the symbols on the reels are not rendered in 3D, the bright colours pop, even on a smaller screen, creating an equally rewarding experience for a mobile user. Just make sure you use landscape orientation!

Big Bass Bonanza™ — Pros & Cons

Do we have the potential to lure massive wins in our hook, as the slot name promises? Let’s fish around for the answers together:


  • High RTP score
  • Broad betting range
  • The fisherman helps us gain instant cash prizes
  • Popular maritime theme
  • Free spins can be re-triggered, with increasing win multipliers


  • Low maximum win
  • Relatively small number of extras
  • Rudimentary visuals (2D symbols)
  • No unlimited win multipliers during free spins
  • Dull base game (no cascading reels or Wild substitutions present)

Big Bass Bonanza™ vs Floating Dragon Hold & Spin

It’s time for the battle of the giants! How do these two hit titles from Pragmatic Play fare against each other in terms of RTP, win potential, and features? Let’s find out!

When it comes to layout, betting range and RTP, we have a tie: both slots have five reels, three rows, and 10 paylines, an identical RTP score of 96.71% and betting options of 0.10-250. However, when talking about maximum wins, the crown goes to Floating Dragon Hold & Spin (5,000x), compared to the modest 2,100x that we can get from Big Bass Bonanza™.

The bonus features are quite similar: free spins, Wilds, and money symbols. With that said, Floating Dragon is slightly more advantageous because, even if you don’t win 20x your stake during the Hold & Spin feature, you’ll still be guaranteed three more respins. In terms of volatility, Big Bass Bonanza™ incurs less risk (4/5) compared to Floating Dragon Hold & Spin (5/5).

As for themes and visuals, we have a close call: both games feature wildly popular themes (Asia and fishing). The graphics are quite polished, though a bit more detail-oriented in Floating Dragon — here, we have the realistic movement of birds flying in the background, and the temple name tag swinging alongside them, creating a dream-like state for the players.

All things considered, our team now has the verdict:

  Big Bass Bonanza Floating Dragon Hold & Spin
Winning Potential 50% 75%
RTP 50% 50%
Bonus Features 50% 75%
Theme 50% 50%
Visuals and Audio 50% 75%

Other Big Bass Bonanza™ Games

There is something uniquely appealing about online slots set out at sea — perhaps it’s the call of the unknown and unexplored stretches of water sparking our thirst for adventure. This would explain the growing popularity of fishing-themed and pirate-themed video slots, by extension. After all, we know less about the Earth’s own oceans than outer space!

That is also why Pragmatic Play released an entire series of Big Bonanza games to capitalise on all of the below.

Big Bass Bonanza Megaways™

When Big Time Gaming began to license their uber popular Megaways™ engine, many developers took this opportunity to add multiple paylines and other extras to original slots. Thus, Big Bass Bonanza Megaways™ was born — a six-reel video slot with up to 46,656 ways to win and a 96.7% RTP. Although this layout is more restrictive compared to other Megaways™ slots, it’s a fantastic start!

Big Bass Bonanza Megaways™ kept the same underwater design we’re accustomed to, only in a high- volatility format. What’s more, the base game was improved with the famous tumbles, which destroy winning symbols and make room for new ones, helping you score consecutive wins.

The fisherman and the fish symbols were kept, rewarding us with free spins, win multipliers, and cash prizes. The biggest improvements are the Bazooka and Dynamite features, which add fish symbols onto the screen or destroy all symbols, aside from the fish.

#2 Big Bass Bonanza – Keeping It Reel

Reel Kingdom and Pragmatic Play once again joined forces in October 2022 with Big Bass Bonanza – Keeping It Reel. This time, the soundtrack rolling in the background is different, but just as energetic!

The layout chosen is quite basic: five reels, three rows, and 10 paylines, with a predictable RTP score of 96.07%. However, we’re pleased to see an upgrade in the maximum win potential to 10,000x.

A very volatile slot, this game is fantastic for high rollers due to its flexible betting range: 0.10 – 250 per spin. The Free Spins bonus round was also improved with the regular Wild and golden Wild symbols, both of which get collected on the multiplier trail.

Lastly, if you don’t have the patience, you can buy the bonus for a cost of 100x or activate the Ante Bet to increase your chances of triggering free spins.

#3 Big Bass Splash


A base game screenshot of Pragmatic Play’s Big Bass Splash slot. (Source: Pragmatic Play)

Launched in the summer of 2022, Big Bass Splash came with mild changes in design and colour saturation, signalling that our fisherman is exercising his passion in broad daylight this time.

The usual five-reel, three-row, and 10 payline configuration was kept, the volatility levels are set at mid-high, and the maximum win is a decent 5,000x. So far so good, especially if we factor in the high RTP of 96.71%.

Now for the bread and butter: the features. The Free Spins bonus is back with a catch (no pun intended). If two Scatters fall, a random feature gets triggered, bringing another Scatter onto the reels. If these two Scatters move down one position, the reels without any Scatters get a respin. Buying the bonus is possible, as well, for 100x your stake.

#4 Christmas Big Bass Bonanza™

It’s the season to be…fishing? Yes, precisely! Our friendly protagonist has probably moved somewhere closer to the Nordics and is fishing under frozen water. The fish wear Christmas hats, the sea vegetation is replaced by a decorated Christmas tree, and even our fishing equipment is wrapped in a fancy bow!

With such presentation, Christmas Big Bass Bonanza™ immediately tugged at our seasonal slots-loving strings. Launched at the start of December 2021, this Christmas extravaganza has the same layout we’re used to: five reels, three rows, and 10 paylines, a medium level of volatility and a high RTP of 96.71%.

Santa gifts us with a smaller maximum win of 2,100x, but we have a few more extras present, such as up to 20 free spins with fish money symbols that award cash prizes. In addition, we have a Father Christmas Wild symbol, which collects these money values on our behalf!

#5 Bigger Bass Bonanza

It’s back — bigger, brighter, and better! Launched in September 2021, Bigger Bass Bonanza proposes a slightly different layout of five reels, four rows, and 12 paylines. Moreover, the scenery also has some interesting changes. It appears that our fisherman character is presently on holiday — somewhere in Vegas, judging by the palm trees and electronic 80s music!

With a high level of volatility and an RTP of 96.71%, we’re starting our vacation quite nicely. On top of this, we’re also granted up to 20 free spins with Wild symbols and fish money icons, whose values get collected by the angler. Another cool fact is that your wins during the free spins can reach a maximum of 4,000x, which is a welcome uptick!

#6 Bigger Bass Blizzard


A base game screenshot of Pragmatic Play’s Bigger Bass Blizzard slot. (Source: Pragmatic Play)

Last on our list we have the Bigger Bass Blizzard, released on 28 November 2022. Same as the previous Christmas title, we are back among snowy ice caps and trees — our fisherman is even equipped with a snowmobile to reach his next fishing spot! If that’s not dedication, we don’t know what it is!

This game has a layout of five reels, four rows, and 12 paylines. The RTP has been slightly lowered — 96.08%, but the maximum win remains a decent 4,000x. If we land two Scatters, a hook appears on the screen to bring the third one in view.

Both Wild symbols and fish money symbols are present during free spins, with a 10x maximum multiplier possible. Paying 100x your bet will instantly trigger the bonus. Furthermore, the Extra Chance option doubles your stake and your chances of triggering free spins!

Our Big Bass Bonanza™ Slot Verdict

Big Bass Bonanza™ remains a classic in the maritime genre. It builds on the success of Blueprint Gaming’s Fishin’ Frenzy, which first opened our appetite for the big catch. Our main character, the fisherman himself, can help us turn random symbols into fish and grace us with a 10x multiplier! Alongside free games and a generous RTP, there’s plenty to hook in our fishing rod, so we’ll be parking our boat and lying in wait!

Other Slots To Try Out

Big Bass Bonanza™ FAQs:

This game has an estimated RTP score of 96.71%. This is the range given by the developer, so do keep in mind that some online casinos may lower the RTP.

We’re glad you asked! There are many existing and new slot games with similar themes available, for example Fishin’ Frenzy, Ocean Rush, and Golden Catch.

The maximum win is capped at 2,100x. Depending on the stakes used, this puts the real- money values between £/€/$210 and £/€/$525,000.
