Big Bass Bonanza

By Becky Mosley | Updated 28 May 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.

About Big Bass Bonanza Slot

The slot is played across 5 reels, 3 rows, and 10 fixed paylines. The betting ranges between 10p up to £250 per spin, suitable to all players, whatever their budget.

The main draw of the Big Bass Bonanza slot is the free spins. During this feature, if a fisherman symbol appears, he collects all the values on the fish symbols. Wilds retrigger the bonus feature where multipliers are present, and a top prize of 2,100x is up for grabs.

Design

Reel Kingdom has paired back the slot, opting for a more simplistic design with only one feature.

Fishing is Big Bass Bonanza’s inspiration, which is apparent as soon as you load the game. The transparent reels sit underwater and are separated by bubbles. All aspects of fishing are on the reels, including various fishing tackle equipment.

Symbols on the reels include the usual low-value royal card suits and numerous species of fish and fishing tackle. The most lucrative symbol is the fishing float; if 5 lands on a pay line on a single spin, it awards 200x the bet.

The fisherman stands for the wild. He only shows up in the bonus feature. He can replace all symbols except the Big Bass Scatter symbol.

Big Bass Bonanza RTP and Volatility

Big Bass Bonanza is perfect if you do not like highly volatile slots. It’s at a medium level, and the bigger wins come from the bonus feature. This is due to the collect mechanic and multipliers that can award a top prize of 2,100 times the bet. Expect to see more frequent wins but not massive amounts.

Big Bass Bonanza has a decent RTP of 96.7%. This is slightly higher than the industry average. However, I mentioned above that Pragmatic Play offers its games to online casinos with varying RTP.

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 to 5 scatters to activate the free spins anywhere on the reels. Once triggered, the number of triggering scatters determines the free spins you’ll play.

3 scatters = 10 free spins

4 scatters = 15 free spins and

5 scatters = 20 free spins

Remember I spoke of the fish symbols? These all have cash values attached 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 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

Big Bass Bonanza slots were released in 2020. After such huge success, Pragmatic Play has since developed more slots in the series.

The Bigger Bass Bonanza Slot was the second released in the fishing series of slots. Bigger Bass Bonanza offers a top prize of 4000x. Additionally, the slot is similar to the original, but it features higher volatility. The original may be better if you feel comfortable playing a slot with less risk.

Many well-known software developers have decided to improve their popular games with the Megaways feature. This mechanic allows for 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. The fish all have Christmas hats, the royal symbols are covered in snow, and various Christmas-related 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 good 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.

Big Bass Bonanza – Our Verdict

Big Bass Bonanza has become something of a modern classic – a staple in the slots world and the game that kicked off one of the most recognisable series in online casino history. Developed by Pragmatic Play in partnership with Reel Kingdom, this cheerful, fishing-themed slot combines simple gameplay, high volatility, and just the right splash of bonus potential to keep players hooked.

At the heart of the game is the Free Spins feature, where fish symbols carry instant cash values, and the fisherman Wild reels them in when he appears. The more fishermen you collect, the more free spins and multiplier boosts you unlock – adding a nice bit of tension and anticipation to every bonus round.

Visually, Big Bass Bonanza keeps things colourful and light-hearted, with cartoon-style graphics and a laid-back soundtrack that perfectly fits the fishing theme. It’s not groundbreaking in terms of design, but it doesn’t need to be – the charm is in its simplicity.

With a 96.71% RTP, a 5,000x max win, and a betting range from 10p to £250 per spin, it caters to just about every type of player, from casual spinners to more serious punters. And let’s be honest – who doesn’t enjoy seeing the fisherman land just in time to scoop a screen full of juicy cash fish?

While the game doesn’t reinvent the wheel, it delivers on all fronts: clear mechanics, good win potential, and just enough unpredictability to keep things exciting. It’s easy to see why Big Bass Bonanza became such a hit – and why it’s still one of the most played slots at UK casinos today.
