Big Bass Splash has more bonus features than its base-game presentation suggests. The 5×3 reels look like a classic line-pay slot, but the bonus engine stacks five distinct mechanics that combine to produce the 5,000× max-win ceiling: scatter-triggered free spins, a pre-bonus modifier picker, money fish symbols, the sticky-wild multiplier ladder, and the Bonus Buy. This article walks through each feature, what it does, and how they interact.

Feature 1 — Scatter trigger
The golden scatter symbol is the entry point to every bonus mechanic. Three or more scatters anywhere on the reels (positions don't matter) triggers free spins:
| Scatters | Free spins awarded |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
The scatter is non-line-dependent — it doesn't need to land on adjacent reels or on a payline. Any three positions across the 5×3 grid count.
Trigger rate is roughly 1 in 250 spins at default settings. Big Bass Splash does not have an Ante Bet feature (some Pragmatic slots like Gates of Olympus do); you cannot pay extra per spin to double the trigger rate. The two ways to access the bonus are: wait it out, or use the Bonus Buy.
Feature 2 — The 5-card modifier picker
This is where Big Bass Splash deviates from its 2020 predecessor. Before free spins start, you're shown five face-down cards. Tap one. The card flips to reveal which of five modifiers applies for the entire round.
Extra Fish
Increases the density of money fish symbols on the reels during the bonus. Bigger collections per Fisherman trigger, but slightly reduced retrigger probability.
Best for: Players who want more action per spin and steady collection volume.
Extra Fisherman
Increases the density of Fisherman wild symbols. Means money fish get collected more frequently and sticky-wild count climbs faster toward the 10× multiplier tier.
Best for: Players chasing the multiplier ladder — fastest path to max win.
Extra Dynamite
Adds dynamite frames to the bonus. When a dynamite frame appears, it detonates and clears the board, paying out everything visible plus a guaranteed money fish collection.
Best for: Players who want a guaranteed mid-round payout to lock in profit.
Hooks
Guarantees that at least the first spin of the bonus clears a line of money fish via a "hook" mechanic. Provides a baseline payout floor.
Best for: Risk-averse players who want some bonus payout assured.
Bazookas
The rare all-or-nothing modifier. Adds explosive bazooka frames that can clear large sections of the board with high-multiplier collections. Highest variance of the five.
Best for: Players willing to gamble on either a small bonus or a massive one.
Important: the modifier is decided randomly by which card you tap. There is no way to preview which card holds which modifier. Picking the centre card vs left card has no statistical advantage. The decision is decorative.
Feature 3 — Money fish symbols
The money fish is the signature mechanic and the engine of every big bonus payout. During free spins:
- Money fish symbols replace regular bass symbols on certain spins.
- Each money fish carries a random cash value between 2× and 5,000× your bet (in fixed increments — see the value table in our money symbols article).
- The cash value is visible on the symbol — the cowboy hat icon at the bottom of the fish shows the multiplier.
- Money fish do not pay until a Fisherman wild collects them.
This is the core mechanic that distinguishes Big Bass Splash from a generic line-pay slot. The bonus round becomes about waiting for the Fisherman to land and trigger collections, rather than waiting for line wins.
Feature 4 — Fisherman wild + sticky wild multiplier ladder
The Fisherman wild has two functions:
Function A — substitute in base game. Throughout normal play, the Fisherman acts as a standard wild, substituting for any non-scatter symbol to complete line wins. No collection mechanic in base game.
Function B — collect + stick in free spins. During the bonus round, every Fisherman wild that lands:
- Collects all visible money fish on the reels. Their values are summed and added to the bonus total.
- Sticks in place for the rest of the round. It stays on its position until the bonus ends.
- Increments the sticky-wild counter displayed above the reels.
The sticky-wild counter unlocks the multiplier ladder:
| Sticky wilds | Multiplier active |
|---|---|
| 1 – 3 | 1× (no multiplier — standard collection) |
| 4 – 7 | 2× all subsequent collections doubled |
| 8 – 11 | 3× all subsequent collections tripled |
| 12+ | 10× maximum — all collections 10× |
Each multiplier tier applies to every collection from that point forward in the round. Reaching 12+ sticky wilds locks the round into 10× collections for the remaining spins — the prerequisite for max-win payouts.
The ladder resets between bonus rounds — you can't carry sticky wilds from one bonus to another.
Feature 5 — Retriggers
Three or more scatters landing during free spins adds +10 spins to the running counter. Retriggers stack — multiple retriggers in a single round are possible, each adding 10 spins. The longest documented Aussie streamer round during 2024-2026 lasted 80 spins with three retriggers.
Retriggered rounds are where the 10× multiplier becomes lethal. A 30-40 spin round with the ladder maxed at 10× from spin 15 onward stacks more collections than a clean 10-spin round can produce.
Feature 6 — Bonus Buy
Big Bass Splash includes a Bonus Buy button (visible on the side of the reels). Tapping it lets you pay roughly 100× your current stake to skip straight to the modifier picker and free spins round.
Math check at A$1 stake:
- Cost: A$100.
- Average bonus payout: ~100-150× total stake (so A$100-A$150).
- Expected value: roughly even with the cost over many buys.
The Bonus Buy is not a profitable strategy in the long run — it's a time-saver. Pragmatic Play prices the buy at the long-run average bonus value, so you neither gain nor lose meaningful EV. You're paying for the entertainment of going straight to the bonus.
Important: most AU casinos disable Bonus Buy when playing on welcome-bonus funds. You can only use it with real (non-bonus) deposits. We cover the full economics in our Bonus Buy article.
How the features combine
Worked example of a strong bonus round:
- Trigger — 4 scatters land → 15 free spins.
- Modifier pick — you tap Extra Fisherman.
- Spins 1-5 — 3 Fishermen land (more frequent due to modifier) → 3 sticky wilds, 4 money fish collected → small payouts.
- Spins 6-10 — 4 more Fishermen → sticky count = 7 → 2× multiplier active.
- Spin 11 — 2 Fishermen land while 6 money fish visible (mix of 5× to 50× values) → 6 fish collected, sum × 2 = solid payout.
- Spin 12 — 3 scatters land → +10 retrigger spins.
- Spins 13-20 — 5 more sticky wilds → count = 14 → 10× multiplier locked.
- Spins 21-25 — 10× multiplier compounds every collection.
- Final spin — 3 Fishermen land, 5 money fish on screen including a 200× value → 250× sum × 10 = 2,500× collection.
- Total bonus payout — approximately 800× total stake.
That's the rhythm of a strong session. The 5,000× max is just this exact sequence with higher-value fish under the cap.

Quick FAQ
Can I pick a modifier without spinning a free spin first? No — the modifier picker only appears after a scatter trigger or Bonus Buy. There's no preview mode.
Are sticky wilds removed if the bonus retriggers? No — they persist for the entire round, including all retriggers.
What's the max multiplier I can reach? 10×. Even if you collect 30 sticky wilds, the cap stays at 10×.
Can I have two modifiers active at once? No — one modifier per bonus round.
Does Bonus Buy give me a better modifier? No — modifier selection is random regardless of how the bonus was triggered.
Why doesn't every spin in the bonus have a money fish? Money fish appear on a randomised subset of spins. The modifier picked affects density — Extra Fish maximises money-fish appearances.
Are these the same features as the original Big Bass Bonanza? No — Big Bass Bonanza has a simpler 2× → 3× → 4× sticky-wild ladder (max 4×) and no modifier picker. Big Bass Splash's 10× cap and 5-card picker are major upgrades.
