For total beginners. Read this once and you'll understand the game well enough to spin sensibly. ~10 minute read.
Bigger Bass Splash looks simple from the lobby — a tropical fishing slot with cartoon fish, a fisherman in a Hawaiian shirt, and a big spin button. And it is simple. But there are five or six small choices (bet size, Ante Bet on/off, auto-spin limits, Bonus Buy, where to put your stop-loss) that turn a 20-minute session from a fun introduction into either a costly mistake or your first taste of the 5,000× ceiling. This walkthrough takes you from "I just opened the game" to "I know what I'm doing" without any of the affiliate-pitch fluff.

Step 1 — Demo first, real money second
Every honest beginner walkthrough starts the same way: play the free demo for at least 50-100 spins before depositing. There's no AUD on the line, the math is identical to the real-money version, and you'll see at least one or two near-bonus situations that teach you the rhythm of the game.
In demo mode you'll learn the answer to questions you didn't know you had: Does the auto-spin button stop on bonus trigger? How loud is the bonus animation? How long does a single spin take if I'm doing 100 in a row? All of that is free to discover in demo. Once you're spinning real money it's too late to be experimenting with settings.
Vegasnova, Joe Fortune, GreatSlots, and CasinoRocket all offer the demo without forcing you to register first. The Pragmatic Play official product page also has a built-in demo if you want a neutral environment.
Step 2 — Understand the grid before you spin
Bigger Bass Splash is a 5-reel, 4-row slot with 12 fixed paylines. "Fixed" means you can't turn paylines on or off — they're always active. You bet a total stake per spin and the game divides it across the 12 lines automatically.
The reels spin from left to right. Wins are formed when three or more matching symbols land on adjacent reels starting from the leftmost reel along one of the 12 lines. The leftmost-reel rule is important — five matching K symbols spanning reels 2, 3, 4, and 5 with a gap on reel 1 do not pay. They have to start at reel 1.
The exception is the scatter (the bobber/buoy symbol), which pays from anywhere — and the money fish symbols, which we'll cover in step 5.
Step 3 — Set your bet size
Click the small "+" and "-" buttons next to the spin button to cycle through bet sizes. Bigger Bass Splash accepts bets from A$0.10 to A$200 per spin in AUD.
The right bet size is the one that lets you spin for a reasonable length of time without burning your session bankroll on a dry stretch. A useful rule for high-volatility slots like this:
| Your session bankroll | Suggested bet size | Spin count if no wins |
|---|---|---|
| A$20 | A$0.20 | 100 spins |
| A$50 | A$0.50 | 100 spins |
| A$100 | A$1.00 | 100 spins |
| A$200 | A$2.00 | 100 spins |
| A$500 | A$5.00 | 100 spins |
The math: bet roughly 1% of your session bankroll per spin. That gives you about 100 dry spins before you're out of budget, and 100 spins is usually enough to see one bonus trigger or several near-misses on a 96.50% RTP slot of this volatility class.
Step 4 — Decide on Ante Bet (yes or no)
This is the most important decision in your first session, and almost every new player gets it wrong by ignoring the question.
Ante Bet is a toggle in the side menu (look for a button labelled "Ante Bet" or a small "+25%" indicator). When ON:
- Your total stake per spin increases by 25% (A$1.00 → A$1.25).
- The natural frequency of scatter symbols appearing doubles.
- All other math is unchanged — same RTP, same max win, same paylines.
The math works out: you're paying 25% more per spin for roughly double the bonus trigger rate. Most simulations show Ante Bet ON is marginally better long-term value than Ante Bet OFF if you're playing for bonus rounds (which is where most of the game's RTP lives in a high-volatility slot). If you're casually spinning for the tumble entertainment, leave it OFF and stick to base game.
Step 5 — Recognise the money fish symbols
The money fish symbols are why Bigger Bass Splash exists. They look like cartoon fish with a dollar value printed on them — anything from 2× to 5,000× your spin stake. The values are pre-set on each individual fish symbol that lands on the reels in a given spin.
Here's the key trick: money fish symbols pay nothing in the base game on their own. They only count when a fisherman wild lands on the same screen. When that happens, the fisherman "collects" every money fish on the grid and pays out the sum of their values.
So in base play, you'll see big-value money fish (say a 500× and a 200× fish on screen) and nothing happens because there's no fisherman to collect them. This is intentional — the money fish mechanic only becomes lucrative in the free spins round, where fishermen become sticky and collect fish on every spin until the round ends.
Step 6 — Trigger the bonus (free spins)
The scatter symbol is a bobber/buoy floating on water. Land 3 anywhere on the grid and you're in:
| Scatters landed | Free spins awarded |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 (full grid) | 20 |
In the round, fishermen become sticky wilds with a personal multiplier. Each time a sticky fisherman collects fish, his multiplier ticks up — by 1×, 2×, or 3× — capped at 10×. When his 10× multiplier collects a 500× money fish, that's a 5,000× hit from a single symbol. That's the math behind the max-win cap.
You can retrigger the bonus from within the bonus — land 3+ more scatters and you'll add more free spins on the same scale (3 → +10, 4 → +15, 5 → +20).
Step 7 — Auto-spin sensibly
Auto-spin is your friend during long sessions and your enemy during emotional ones. To open auto-spin, click the icon next to the spin button (looks like a circular arrow). You'll see options for 10, 25, 50, 75, or 100 spins.
Always set a loss limit before launching auto-spin. Use the "Stop on balance decrease by A$X" option to halt the queue if you've lost more than you're comfortable with. Auto-spin without a stop condition is the most common cause of bankroll blow-ups in pokies of this volatility class.
Step 8 — Know when to walk away
This isn't slot-strategy waffle, it's the only piece of actually-useful advice in any pokie article: set a session time limit and a loss limit before you start spinning, and walk away when either is hit. Bigger Bass Splash is fun because of the bonus rounds, and bonus rounds are statistically rare. If you've spun 150 times with no bonus, the next spin is not "due" — every spin is independent. Walk away, come back tomorrow, or switch to demo for a while.

Beginner FAQ
How long does one spin take? ~2.5 seconds default. Faster in "turbo" mode if your casino supports it (usually ~1.5s).
Can I influence the outcome? No — every spin is determined by the casino's certified RNG. There's no skill, no pattern, no "hot streak" you can predict.
What happens if I close the game during free spins? Your bonus state is saved. Reopen the game and you'll resume from where you left off. Don't worry about disconnections.
Do free spins use my real bet level? Yes — free spins are calculated at the bet level you triggered them at. Don't trigger at A$0.10 and expect A$20 free spin payouts.
Can I play multiple Pragmatic Play games at once? On desktop yes (in separate browser tabs). On mobile no (one tab at a time).
Is Bigger Bass Splash fixed (rigged)? No — RNG certified by GLI and BMM Testlabs. The casino can't influence individual outcomes. They can choose which RTP variant to run (always verify in-game; the four featured AU casinos run the 96.50% default).
