Tour of every bonus mechanic. Free spins, money fish, sticky wilds, modifiers, Ante Bet, Bonus Buy — what each one does and how they interact.
Bigger Bass Splash crams more bonus features into a single pokie than most Pragmatic Play releases. There's the headline free spins round, the money fish symbol mechanic, sticky multiplier fishermen, five different pre-bonus modifiers (Extra Fish, Extra Fisherman, Extra Dynamite, Hooks, Bazookas), the Ante Bet scatter-boost option, and the Bonus Buy path. Each feature interacts with the others. This article walks through every one without skipping the interactions, so you understand what's actually happening when the screen erupts during a bonus round.

Feature 1 — Money fish symbols
The defining feature of the entire Big Bass franchise. Money fish symbols are special icons that land on the reels carrying a pre-printed cash value between 2× and 5,000× your stake. Each individual money fish symbol that lands has its own value, drawn from the reel-strip distribution.
- In base play, money fish symbols pay nothing on their own. They sit on the grid as decoration unless a fisherman wild lands too.
- In free spins, money fish are everywhere. Each one a fisherman wild collects pays out at its printed value.
Most money fish carry small values (2×-25×). A handful carry mid-range (50×-200×). Very rarely you'll see a 500× or 1,000× fish, and exceptionally rarely a 5,000× fish.
Feature 2 — Fisherman wild symbol
The fisherman is the wild — a cartoon Hawaiian-shirted angler with a fishing rod. He substitutes for all regular symbols (low-pays, mid-pays, high-pays) on standard payline wins, but his real power is in the bonus round.
- In base play, the fisherman is a standard wild substituting in paylines.
- In free spins, the fisherman becomes a sticky wild with a personal multiplier. He stays on the reels for the rest of the round, collects all money fish on screen each time he appears, and his personal multiplier grows by 1×, 2×, or 3× each collection cycle. Cap: 10× per fisherman.
Feature 3 — Free spins round (the main event)
Trigger by landing 3 or more scatter symbols (the bobber/buoy) anywhere on the grid:
| Scatters | Free spins |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
In the round:
- The grid stays 5×4 with the same 12 paylines.
- Each fisherman that lands becomes sticky for the remainder of the round.
- Each sticky fisherman has a personal multiplier that increases each time he collects money fish.
- Money fish landing on the grid are collected by every sticky fisherman present when they appear.
- Retriggers: 3+ more scatters during the round adds more free spins on the same scaling (3 → +10, 4 → +15, 5 → +20).
Feature 4 — Sticky wild multipliers
This is the math engine of the free spins round. When a fisherman lands during free spins:
- He becomes sticky.
- He gets a starting personal multiplier of 1×.
- Each time he collects money fish (on any subsequent spin during the round), his multiplier increments by 1×, 2×, or 3× (randomly).
- His multiplier caps at 10×.
When he collects a 100× money fish at his 5× multiplier, that's a 500× payout from that single fish-fisherman interaction. When two sticky fishermen each at 6×-8× multipliers both collect on the same screen of money fish, the compounding gets impressive fast.
Feature 5 — Pre-bonus modifiers (the wildcard feature)
Bigger Bass Splash adds a layer that the original Big Bass Splash didn't have: random pre-bonus modifiers can fire at the start of certain bonus rounds. There are five of them:
| Modifier | Effect |
|---|---|
| Extra Fish | Additional money fish symbols are added to the reels for the round, increasing collection density. |
| Extra Fisherman | Additional fisherman symbols are seeded onto the reels at round start, accelerating sticky-wild stacking. |
| Extra Dynamite | Random explosions clear card-royal symbols mid-round, replacing them with money fish or fishermen. |
| Hooks | Hooks attached to fishermen pull money fish from adjacent positions into the collection zone. |
| Bazookas | A spectacular round-finale modifier — a "bazooka" fires money fish onto the grid in the round's final spin. |
Modifiers don't trigger on every bonus. They're random extras that can elevate a standard 50× round into a 300×+ round. There's no way to influence which modifier (if any) fires.
Feature 6 — Ante Bet
The single biggest change vs the original Big Bass Splash. Ante Bet is a toggle in the game settings:
- OFF: standard stake, standard scatter frequency. Bonus triggers around 1 in 220 spins.
- ON: stake is increased by 25% (A$1.00 → A$1.25), and scatter frequency is doubled. Bonus triggers around 1 in 110 spins.
Ante Bet doesn't change the RTP (Pragmatic publishes both modes at 96.50%). It just shifts how the volatility falls — you pay slightly more per spin in exchange for more bonus rounds, which is where the game's RTP lives. Most analytical players run Ante Bet ON.
Feature 7 — Bonus Buy
For when you don't want to grind the base game waiting for scatters. Bonus Buy lets you pay roughly 100× your current stake to launch straight into the free spins round.
| Stake | Bonus Buy cost |
|---|---|
| A$1.00 | A$100 |
| A$2.00 | A$200 |
| A$5.00 | A$500 |
| A$10.00 | A$1,000 |
Bonus Buy guarantees you a 10-spin bonus (you don't get to choose which scatter-count trigger you'd buy — most casinos give the 10-spin minimum unless you specifically pay extra for higher tiers, which most AU casinos don't offer). RTP on the Bonus Buy path is published at ~96.70%, slightly higher than the base game.
Watch out: Bonus Buy is usually excluded from welcome bonus play. If you're playing on bonus funds, the casino won't let you click the Bonus Buy button.
How the features interact
A typical strong bonus round combines several features:
- Ante Bet ON doubles your trigger rate.
- You hit a 5-scatter trigger → 20 free spins.
- The round opens with a random Extra Fisherman modifier → 2 sticky fishermen seeded at round start.
- Both fishermen accumulate 10× multipliers by round end.
- A retrigger at spin 12 adds another 15 spins.
- Bazookas modifier fires on the final spin, painting the screen with money fish.
That's the recipe for a 1,000×+ result. Most rounds don't combine that many positives — but understanding which features compound helps you appreciate when they do.

Bonus features FAQ
Do modifiers always fire? No — they're random. Some bonus rounds have zero modifiers; some have one. None of the rounds we've tested fire more than one modifier at a time.
Can the sticky fisherman multiplier exceed 10×? No — capped at 10×. This is what holds the max-win ceiling at 5,000×.
Does Ante Bet improve sticky wild stacking? Indirectly — more bonus triggers means more chances for high-multiplier rounds. The math inside each round is unchanged.
Can I use Bonus Buy with bonus funds? Almost never — most casinos disable Bonus Buy when playing on welcome-bonus credit. Use real cash deposits for Bonus Buy access.
Are bonus rounds the same length whether I trigger or buy? Bonus Buy usually gives the minimum 10-spin trigger. Natural triggers can give 10, 15, or 20 depending on scatter count.
Does the retrigger reset my fisherman multipliers? No — sticky fishermen keep their accumulated multipliers across retriggers within the same round.
