The 12 paylines explained
Bigger Bass Splash uses 12 fixed paylines on a 5×4 grid. They're standard left-to-right lines that visit every position on the grid at least once across the 12 lines. Because they're fixed, your bet is divided evenly across all 12 — you don't need to "select" which lines to play.
Paylines pay left to right starting from the leftmost reel. A matching combination that doesn't begin on reel 1 is not a win. The only exception is the scatter, which pays from anywhere.
RTP variants — the trap
Pragmatic Play distributes Bigger Bass Splash in three RTP versions so operators can choose which to host:
| Variant | RTP | Where it's used |
|---|---|---|
| Default (high) | 96.50% | Trusted brands, full transparency |
| Reduced (med) | 95.50% | Some EU regulated markets, mid-tier offshore |
| Reduced (low) | 94.50% | Aggressive-margin offshore operators |
A 1.0 percentage point RTP drop translates to roughly $10 less return per $1,000 wagered over the long run. It's not a small thing.
The four featured AU casinos (Vegasnova, Joe Fortune, GreatSlots, CasinoRocket) run the 96.50% certified default version. Verify in-game by opening the info panel ("i" icon, usually top-right). The first line of the info panel states the RTP for the build you're actually playing.
Volatility classification
Pragmatic Play's official volatility rating for Bigger Bass Splash is 5/5 (high) on their internal scale. In practice this means:
- Long dry stretches between bonus triggers.
- When a bonus triggers, the variance inside the round is also high — most bonuses land 30×-100×, occasional 500×-1,000× hits, and the very rare 5,000× max-win outcomes.
- Standard deviation of returns per 100 spins is significantly higher than mid-volatility slots like Gates of Olympus 1000 or Sweet Bonanza.
If you're new to high-volatility slots, expect more variance than you've seen on classic Aussie pubs pokies.

Spec FAQ
Is the paytable different in the lower RTP versions? No — same paytable, same symbols, same animations. The difference is in the reel-strip composition (how often each symbol appears on each reel). It's invisible to the player but materially shifts long-run RTP.
Are the 12 paylines configurable? No — they're fixed. You always play all 12.
Why is the money fish payout structure not in the standard paytable? Because money fish carry pre-printed values per individual symbol (one fish might be 5×, another 100× on the same screen). The values are drawn randomly per fish landing.
Is the max win 5,000× per spin or per round? Per spin in base game (unreachable in practice; max base hit is ~50×), and per round (cumulative) in free spins. Once total accumulated wins reach 5,000× during a bonus, the round terminates.
Are there any progressive jackpots? No — Bigger Bass Splash has no progressive jackpot pool. The 5,000× cap is the entire ceiling.
