Big Bass Bonanza is a fishing-themed online slot built by Reel Kingdom and distributed by Pragmatic Play, released back in 2020. If you want to know how to play Big Bass Bonanza slot Australia players will find the setup straightforward: pick a stake, spin five reels, and watch for the fish. Below is a walkthrough of a single round, a breakdown of the free-spins feature, and some things worth checking before you commit real money.
The Grid and the Symbols
The game runs on a 5-reel, 3-row grid with 10 fixed paylines. Fixed means you can't switch lines on or off — all ten are always active.
Wins are formed by landing three or more matching symbols left to right across those paylines, starting from the leftmost reel. If the matching run doesn't begin on reel one, it doesn't count.
The paytable splits into two tiers:
- Lower pays: the card royals — 10, J, Q, K and A.
- Higher pays: dragonflies, tackle boxes, rods and floaters.
Then there are two special symbols: the Bass Scatter, which triggers the bonus, and the money (fish) symbols that do the heavy lifting once you're in free spins.
Walking Through a Single Round
Here's what actually happens from start to finish.
- Set your stake. Use the plus or minus buttons on either side of the Spin tab. Stakes run from a low limit of $0.10 up to $250. That range works out to $0.01 to $25 on each of the 10 paylines.
- Start the spin. Hit Spin and the five reels start turning.
- Wait for all five reels to stop. The round isn't settled until the last reel lands.
- Check the highlighted wins. The game checks your result against the ten paylines and the paytable, and any winning lines light up.
- Watch the Scatters. Three or more Bass Scatters landing in their final positions trigger the free spins feature.
That's the whole loop in the base game. Set a stake you're comfortable with and keep it there — that's the simplest way to play within your limits over a session.
How to Trigger the Free Spins
The bonus round is where this slot earns its reputation. You need at least three Bass Scatters on the reels:
| Scatters landed | Free spins awarded |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
During free spins, the money (fish) symbols come into play properly. Each one carries a cash value, and those values can reach up to 2,000x. On their own they just sit on the reels — you need the Fisherman to cash them in.
How the Fisherman Wild Multiplier Works
This is the mechanic that drives the big results, so it's worth understanding clearly.
- When a Fisherman Wild lands during free spins, it collects the values of every visible money symbol on that same feature spin.
- Every fourth wild you collect retriggers the feature, adding 10 more spins and raising a multiplier.
- The multiplier climbs with each retrigger: 2x on the first, 3x on the second, and 10x on the third.
- After the third retrigger, the feature can't be retriggered again. The 10x is the ceiling.
So the dream run looks like this: fish symbols with decent values stacked on the reels, a Fisherman landing to sweep them, and enough wilds collected to push you through retriggers until that 10x is applied to your collections. It doesn't happen often, but that's the sequence the whole game is built around.
What the Maximum Win Is
The win is capped at 2,100x the stake. At the top wager of $250, that cap equals $525,000. It's a hard ceiling — the game won't pay beyond it on a single round, no matter how the fish and multipliers fall.
RTP: Check Your Own Casino's Version
This is the part Australian players should pay attention to, because the figures published around the web don't agree.
- Several review sites list the RTP as 96.71%, described as one of the highest in the Big Bass franchise.
- One operator, Midnite, lists 94.02%.
- Betty.ca lists 95.67%, dropping to 94.2% in the Alberta market.
That spread tells you something important: operators can run different RTP versions of the same game. A slot that returns 96.71% at one site might be configured at a lower percentage somewhere else. The number on a generic review page isn't necessarily the number running in the game you've loaded.
Before you play, open the game's own information screen (usually the menu or 'i' button) and read the RTP stated there. That's the figure that applies to your session — not the one on a third-party list.
High or Medium Volatility?
Most sources publish the volatility as high, meaning results are spread less evenly than a medium slot — longer gaps between wins, with the bulk of the value concentrated in the free-spins feature. That matches how the game plays, since so much depends on triggering the bonus.
It's worth noting the sources aren't unanimous here either: Swiss4win lists it as Medium, and USA Today's FTW lists it as Medium-High. Either way, expect the base game to feel quiet and the feature to carry the session.
Does It Have a Bonus Buy?
The answer depends on who you ask, which again points back to version differences.
- SlotsMate states the base game has no bonus buy and no ante bet — you can only reach free spins by landing scatters naturally.
- CasinoTop, citing SlotIndex, states a feature-buy option is listed, letting players pay to trigger the bonus directly.
If buying into the bonus matters to you, check the game's interface at your chosen casino. If there's no buy button visible, you're on the standard build and scatters are the only route in.
Is There a Free Demo?
Yes. A free demo of Big Bass Bonanza is available to play online with no download required. The demo runs the same reels and feature as the real-money game, so it's the ideal place to see a few spins, find the stake buttons, and watch the Fisherman Wild collect fish before you decide whether the game suits you.
Running the demo first is the cheapest way to learn the retrigger sequence, since you can let it play out without risking anything.
Big Bass Bonanza vs the Sequels
The franchise has grown, and the names are easy to mix up. Here's what separates the three most commonly confused versions.
Big Bass Bonanza (the original)
The 2020 release covered above: 5 reels, 3 rows, 10 fixed paylines, money symbols up to 2,000x, and a 2,100x max win.
Bigger Bass Bonanza
A different game, not just a reskin. It's played on a 5×4 grid with 12 ways to win and a maximum win of 4,000x the bet. The bigger grid and the ways-to-win structure change how wins are formed compared with the fixed-payline original.
Big Bass Bonanza 1000
A supercharged version with wins up to 20,000x and money symbol values up to 1,000x. The far higher win ceiling makes it the most extreme of the three.
If you load a game expecting the original and find a four-row grid or a 20,000x figure in the info screen, you've opened a sequel. Check the title on the loading screen so you know which maths you're playing.
Before You Start
The original Big Bass Bonanza is a simple slot to operate and a volatile one to play — most of the value sits in a feature you won't hit every session. Set a stake you can run across many spins, try the demo to see the Fisherman mechanic in action, and read the RTP and feature options stated in your own casino's game screen rather than trusting a generic figure. Those three habits cover most of what a new player needs to know.
