Big Bass Bonanza (Pragmatic Play): RTP 96.71%, 2100× – 2026 Test

Big Bass Bonanza by Pragmatic Play has been the undisputed benchmark for fishing slots since December 2020. With a 96.71% RTP, high volatility (5/5), and a max win capped at 2100× stake, this one reshaped the niche. We ran it hard for 18 months on CrazyBet, logging over 18,000 spins to break it down properly: bonus mechanics, real free spins frequency, bankroll approach, and how it stacks up against the rest of the Big Bass line-up. New to slots or already deep into high-volatility games, this guide lays everything out on this iconic title.

What is Big Bass Bonanza?

The first release in the Big Bass series, Big Bass Bonanza sits in that “classic online slot” category. Well… “classic” is a stretch. It dropped in December 2020 and felt like a shift straight away—Reel Kingdom behind it, in partnership with Pragmatic Play.

On paper, it’s as straightforward as it gets: 5 reels, 3 rows, 10 paylines, and a volatility rating locked at 5/5.

The max win? 2100× your stake. Nothing outrageous compared to other titles from the same provider. So why did this one blow up the way it did?

The fishing theme. At the time, it was barely touched in the slot space. Fast forward a few years and we’ve now got around ten Big Bass versions (lost count, honestly). Safe to say Pragmatic Play nailed it.

Big Bass Bonanza – Technical Sheet

How to Play Big Bass Bonanza?

No suspense here, you’ll see straight away that Big Bass Bonanza is very easy to play. We’ll go step by step for beginners. If you’re more experienced, you can skip ahead, we won’t blame you.

1. As soon as the game loads, decide whether you want the music on or off. We keep it on—and not by chance. You can actually tell when free spins might be coming just from the sound intensity… we genuinely like that detail.
2. Next, choose your auto spins: anywhere between 10 and 1,000, up to you. We usually run 100 spins to get a feel for the slot—see how it behaves, whether it’s paying or just burning through balance early.

1. Fast? Slow? Full speed? Pragmatic Play still gives you the choice, which is always a plus. For us, it depends entirely on the mood. Sometimes we let the spins roll slowly to enjoy the atmosphere… other times, we’re just hunting the bonus trigger and slam turbo on to get there as quickly as possible.

And that’s it. As simple as it gets.

Symbols and Payouts on Big Bass Bonanza

Here’s the value of each symbol based on a €1 stake.

Payouts on Big Bass Bonanza by Pragmatic Play

There are 10 different paylines on Big Bass Bonanza. For a win to land, a symbol needs to appear at least once across the first 2 or 3 reels (depending on the symbol) and follow a valid payline.

As you’d expect, the further a symbol connects across the reels, the bigger the payout. One key thing: the slot only pays from left to right.

Bonus Features on Big Bass Bonanza

What really makes Big Bass Bonanza stand out, in our view, is how its bonus worked at launch. Back in 2020, this setup felt genuinely fresh.

Money Symbols and Cash Fish

The fish are the core of the game (makes sense…). But on Big Bass Bonanza, some of them actually carry cash values. From ×2 up to ×2000, the potential can get serious.

There’s a catch though. To collect those fish, you need the fisherman—and he only shows up in the bonus. So forget about chasing max win potential in the base game. It simply doesn’t happen.

Free Spins on Big Bass Bonanza

Free spins… you’ll need at least 3 Scatter symbols in a single spin to trigger them. On this slot, it actually feels like bonuses land fairly often. In our sessions, we saw one roughly every 90 spins on average—which is rare, considering most slots sit well above 100 spins per trigger.

That said, it can be seriously frustrating. The amount of bait on this slot is brutal. You’ll often go through at least ten near-misses before the feature finally fires.

Trigger:

The Fisherman’s Role During the Bonus

The fisherman is the core of the bonus and the key feature of the slot. It’s very straightforward, every time he lands, he collects all the fish with cash values currently on the grid.

If you land 2 fishermen? Both of them collect all the fish. 3 fishermen? Same story… and 4 fishermen? Don’t even think about it—it just doesn’t happen.

Sorry, we like to kill the suspense.

Multipliers and Retriggers up to ×10

You start the free spins with a ×1 multiplier. But there’s a progression meter in play, and every 4 fishermen collected, you move up to the next level.

Every time you hit a new tier, you’re awarded 10 extra free spins and the fisherman multiplier increases. First ×2, then ×3, and finally ×10. We’ve never managed to reach ×10, but we’ve hit ×3 several times.

As you’d expect, those are the moments where you’re praying for high-value fish—×50, ×100, and beyond. We did land a ×200 fish once with a ×3 fisherman… ×600 in a single spin. That one felt good.

Retriggering:

The only way to retrigger during the bonus is by climbing the tiers through fisherman symbols. One thing we noticed: the scatter symbol disappears entirely once the bonus starts.

Dynamite Feature and Random Effects

Sometimes, a fisherman lands with no fish on the screen. When that happens, he can start throwing dynamite onto certain positions.

What’s the point? Behind those explosions, fish with cash values can appear. First time we saw it, it genuinely caught us off guard.

Strategy and Bankroll Management on Big Bass Bonanza

Managing your balance on Big Bass Bonanza is crucial. After more than 18 months on this slot, we’ve put together OUR approach.

It won’t guarantee profit, and it definitely won’t turn the game into a money printer. What it does do is help you stay in the game longer without your balance getting wiped too quickly.

3 Bankroll Tips:

• Bankroll ≥ 150–200× your minimum bet
• Sessions capped at 100–200 spins with clear stop-win/stop-loss limits

Never increase your stake after a bonus drought
