🎣 Big Bass Splash Modifiers — Extra Fish, Dynamite, Bazookas Explained

📘
Last updated: May 2026. Modifier behaviour observed across 200+ bonus rounds at all four featured AU casinos. EV figures are sample-derived, not Pragmatic Play's certified internal numbers.

The 5-card modifier picker is what separates Big Bass Splash from a generic 5×3 line-pay slot. Before each free spins round begins, you tap one of five face-down cards and reveal which modifier reshapes the bonus. Each modifier produces a fundamentally different bonus rhythm — same RTP across all five (Pragmatic balances them) but very different variance, payout distribution, and tactical feel. This article breaks down each modifier with worked examples, sample payouts, and recommendations for which to pick based on your bankroll and risk appetite.

How the picker works

The moment 3+ scatters trigger free spins, the reels darken and 5 face-down cards appear, arranged in a row across the screen. Each card hides one of the five modifiers — assigned randomly to the cards at the moment of trigger.

You tap one card. The card flips, the modifier name is revealed, and the bonus begins. There's no preview. No re-pick. No way to know which card holds which modifier before tapping.

Card positions are randomised per trigger — picking left, centre or right has no statistical advantage. Pick at random; the math is the same.

One modifier per round. The selected modifier applies to all spins in that bonus round, including any retriggers. You can't change mid-round.

Modifier 1 — Extra Fish

What it does: Increases the density of money fish appearing on the reels during the free spins round.

Mechanics:

More money fish per spin (roughly 30-50% more than the default Extra Fisherman modifier).
Standard Fisherman wild frequency.
Standard sticky-wild ladder progression.

Feel: Steady. Money fish stack up faster, Fisherman lands collect more per swing. Less reliant on the multiplier ladder maxing out.

Sample observed bonus round (A$1 stake, A$0.50 line bet — total A$1):

4 sticky wilds reached by spin 8 → 2× multiplier
6 sticky wilds by end → still 2× multiplier
Total fish collected across the round: 18 money fish, values 2× to 200× mixed
Average sum × multiplier: ~95× per collection event
Total bonus payout: 142× total stake = A$142

Variance: Medium. Reliable payouts in the 60-150× range, occasional spikes to 400-800×, rare runs to the cap.

EV from our 40-round sample: ~85× total stake.

Pick this if: You want consistent action and bigger sums per collection. Less reliant on hitting the 10× multiplier tier.

Modifier 2 — Extra Fisherman

What it does: Increases the density of Fisherman wild symbols on the reels.

Mechanics:

More Fishermen land per spin → more frequent collections.
Faster progression up the sticky-wild ladder (the 4 → 8 → 12 thresholds are reached earlier).
Standard money fish density.

Feel: Builds up. Early in the round the action feels modest, but by spins 8-15 the multiplier ladder is at 3× or 10× and every collection pays a multiple of what it would have on Extra Fish.

Sample observed bonus round (A$2 stake):

7 sticky wilds by spin 9 → 2× multiplier
12 sticky wilds by spin 15 → 10× multiplier activated
Retriggered to 25 total spins
Late-round collections at 10× compounded heavily
Total bonus payout: 380× total stake = A$760

Variance: Medium-high. The fastest path to the 10× multiplier, which produces the highest-tier outcomes when retriggers extend the round.

EV from our 40-round sample: ~90× total stake — the highest of the five in our data.

Pick this if: You're chasing the 5,000× ceiling and want to maximise multiplier-tier compounding.

Modifier 3 — Extra Dynamite

What it does: Adds dynamite frame symbols to the reels. When a dynamite frame lands, it detonates and clears the entire board, paying out every visible money fish at once.

Mechanics:

Standard money fish and Fisherman density.
Occasional dynamite frames appear (roughly 1 in 6 spins).
Each dynamite detonation is a guaranteed full collection event, regardless of Fisherman presence.

Feel: Punctuated. Long stretches of standard play, then a dynamite landing produces a sudden big-payout moment as everything on screen detonates.

Sample observed bonus round (A$1 stake):

3 dynamite detonations across 15 spins
Each detonation cleared 3-5 money fish at multipliers (2 detonations at 1× tier, 1 at 2× tier)
Detonation sums: 28×, 47×, 89×
Additional Fisherman collections: 2 events at 2× tier
Total bonus payout: 198× total stake = A$198

Variance: Low-medium. Floor is higher than other modifiers (dynamite guarantees some clears), but ceiling is lower since dynamite clears don't compound under sticky-wild multipliers as efficiently.

EV from our 40-round sample: ~75× total stake.

Pick this if: You want a reliable mid-tier payout floor with reduced bust risk.

Modifier 4 — Hooks

What it does: A "hook" mechanic activates early in the bonus round, guaranteeing a partial line clear of money fish in the first 1-3 spins.

Mechanics:

Hook frames appear in the first 3-5 spins of the bonus.
Each hook frame "reaches" across one row and pulls visible money fish into a guaranteed collection (sums vary based on what's on the reels).
Standard mechanics after the hook clears.

Feel: Front-loaded. The first few spins feel rewarding even on bad random draws, then the round settles into standard rhythm.

Sample observed bonus round (A$2 stake):

Spin 1: hook frame triggered, 3 money fish on the row cleared = 22× (× 1× tier) = 22×
Spin 3: hook frame again, 2 fish = 12×
Sticky wilds reached 5 by spin 10 → 2× multiplier
Subsequent collections at 2× tier: 4 events totalling 76×
Total bonus payout: 110× total stake = A$220

Variance: Low. The early hook clear is a payout floor — even bad rounds tend to clear 30×+ baseline.

EV from our 40-round sample: ~80× total stake.

Pick this if: You're risk-averse and want a guaranteed minimum payout on every triggered bonus.

Modifier 5 — Bazookas

What it does: The high-variance modifier. Adds bazooka frames that can clear large sections of the board with high-multiplier collections, but at lower frequency than dynamite.

Mechanics:

Bazooka frames appear rarely (roughly 1 in 12 spins).
Each bazooka detonation clears 2-3 reels at once — much wider than dynamite's single-board clear.
Bazooka clears can hit multiple money fish simultaneously and apply a bonus multiplier.

Feel: Two outcomes. Most Bazooka bonuses pay modestly (30-80× total stake). A small percentage pay massively (500-3,000×+).

Sample observed bonus round, modest outcome (A$1 stake):

1 bazooka detonation at spin 7 → 3 money fish cleared = 35×
2 Fisherman collections at 1× tier = 18× total
Total bonus payout: 53× total stake = A$53

Sample observed bonus round, big outcome (A$3 stake, recorded March 2026):

2 bazooka detonations: first at 1× tier (62×), second at 3× tier (220× × 3 = 660×)
5 Fisherman collections, last 3 at 10× tier
Total bonus payout: 1,840× total stake = A$5,520

Variance: Highest of the five. Wide outcome distribution.

EV from our 40-round sample: ~95× total stake — the highest of the five, but with the widest variance.

Pick this if: You're variance-tolerant and have bankroll to absorb the bust outcomes while chasing the spike outcomes.

Modifier comparison summary

Modifier	EV (per stake)	Variance	Best for
Extra Fish	~85×	Medium	Consistent action, mid-volume players
Extra Fisherman	~90×	Medium-high	Multiplier-ladder chasers
Extra Dynamite	~75×	Low-medium	Risk-averse, guaranteed mid-payout
Hooks	~80×	Low	Floor-payout seekers
Bazookas	~95×	High	Variance-tolerant max-win hunters

Disclaimer: these EV estimates come from a 200-bonus-round sample, distributed roughly evenly across modifiers. Pragmatic Play's certified internal distributions may be tighter or more uniform than our sample suggests. The math is balanced to 96.71% total RTP, so over very long samples the EV across modifiers should converge.

Should you pick the same modifier every time?

Personal preference, but tactically: yes, pick the same modifier consistently within a session. Switching modifiers every bonus makes it impossible to calibrate your expectations — you'll feel like every bonus is "different" when really you're just sampling different variance distributions.

Most AU streamers we've tracked stick with Extra Fisherman (the multiplier-chaser) or Extra Fish (the steady choice). Bazookas is the streamer-favourite for highlight-reel clips but the bust risk burns through bankroll faster.

Modifier picking — common myths

Myth: "The third card always has Extra Fisherman."
False. Card positions are randomised per trigger. No pattern.

Myth: "If you bet more, you get better modifier odds."
False. Stake doesn't affect modifier distribution. All five modifiers are equally likely regardless of bet size.

Myth: "Bonus Buy gives you a better modifier."
False. Bonus Buy triggers the same modifier picker with the same random distribution.

Myth: "You can re-pick if you don't like the first card."
False. Card flip is final. No re-pick.

Quick FAQ

Are all 5 modifiers equally likely? Yes — 20% chance each per trigger.

Can I see which modifier each card holds before tapping? No — fully hidden until tap.

Does the modifier affect RTP? No — all five contribute to the same 96.71% total RTP, just with different variance profiles.

Which modifier is "best"? Depends on your goal. Extra Fisherman for max-win chasers, Extra Fish for steady action, Hooks for risk-averse, Bazookas for variance-tolerant, Extra Dynamite for floor-payout reliability.

Can I have two modifiers in one round? No — single modifier per bonus, no exceptions.

Does the modifier reset on retrigger? No — same modifier persists through retriggers within the same bonus round.

Why do I rarely see Bazookas land? Bazooka frame density is intentionally low — they're high-impact when they detonate, low-frequency to balance the variance.
