Guide · Updated July 2026
Big Bass Bonanza is a Pragmatic Play video slot with a relaxed fishing-trip theme — a fisherman on a jetty, tackle boxes, lures and a cast of freshwater fish symbols fill the reels instead of the mythology or candy themes of its stablemates. It's one of the three Pragmatic Play titles confirmed at Pantherbet, and it sits at the far end of the welcome package specifically: 100 free spins on Big Bass Bonanza are tied to the third deposit tier, arriving after the Gates of Olympus spins on your first deposit and the Aviator-linked "Avia Spins" on your second.
Structurally, Big Bass Bonanza is a more traditional slot than Gates of Olympus or Sweet Bonanza — it uses a standard reel-and-payline format rather than a tumbling cluster grid, which makes it a slightly gentler entry point for players who find cluster-pays mechanics unfamiliar. What makes it distinctive isn't its base game structure but its bonus round, built around a money-symbol collection mechanic that's become one of the most widely copied bonus formats in the modern slot industry.
How it plays
Landing the fisherman scatter symbol enough times across the reels during base-game play activates the free spins bonus round.
Throughout the free spins feature, a fisherman symbol can land on the reels and "catch" any money-value symbols present elsewhere on the same spin.
Fish and money-value symbols that land during the feature each carry their own cash amount, which is added to a running total collector displayed on screen.
As more money symbols are caught across successive free spins within the feature, the collected total keeps growing rather than resetting between individual spins.
If additional scatter symbols land during the free spins round itself, extra spins are added to the feature, extending how long you have to keep collecting money symbols.
Once the feature's spins are exhausted, the full collected total from every money symbol caught during the round is paid out as your bonus round win.
This retrigger-and-collect format is a different bonus structure to the accumulating-multiplier free spins used in Gates of Olympus — see our Gates of Olympus guide for that comparison.
The ability to retrigger extra spins during the free spins feature is what gives Big Bass Bonanza's bonus round its distinctive rhythm compared to a one-shot bonus round with a fixed number of spins. Every additional scatter landed during the feature extends the round, which extends the window in which more money symbols can be caught and added to the collector total — meaning a bonus round that keeps retriggering can, in principle, run for a meaningfully longer stretch and accumulate a larger combined total than a round that ends after its initial allotment of spins.
This design gives Big Bass Bonanza a slightly different volatility feel to Gates of Olympus or Sweet Bonanza's multiplier-driven rounds. Rather than a single dramatic multiplier moment deciding the bulk of a win, Big Bass Bonanza's payout builds incrementally across a series of individual catches, which can feel more like a steady accumulation than an all-or-nothing multiplier spike — though the overall size of any given bonus round, including how many retriggers occur and how many high-value money symbols land, is still entirely governed by the game's RNG and can vary widely between one triggering of the feature and the next.

Mzansi Pro-Tip
Because your Big Bass Bonanza free spins only unlock with your third deposit at Pantherbet, plan your deposit sequence deliberately if this is the title you're most interested in — depositing three smaller amounts across separate sessions gets you through all three welcome tiers, including Gates of Olympus on deposit one, Aviator spins on deposit two, and Big Bass Bonanza on deposit three, rather than depositing your full intended budget in one go and missing later tiers.
Once you're in the bonus round, resist the temptation to think a slow start to the feature means it's "over" — retriggers can arrive at any point up until the very last spin of the round, and a feature that looks quiet through its first several spins can still extend significantly with a well-timed scatter.
The clearest distinction between Pantherbet's three headline titles is structural. Gates of Olympus and Sweet Bonanza both use tumbling or cluster-based grids with multiplier symbols that can produce a single dramatic spike in a winning sequence. Big Bass Bonanza uses a traditional reel-and-payline base game and delivers its biggest payouts through a retriggerable collection mechanic instead — a bonus round that builds value incrementally across potentially many spins rather than through one large multiplier moment. Both approaches are widely regarded as capable of producing significant wins, but the way a session actually feels differs: Big Bass Bonanza's collection format tends to give more visible, incremental feedback throughout a bonus round, while Gates of Olympus and Sweet Bonanza's multiplier systems tend to concentrate excitement into a smaller number of standout tumbles. See our Gates of Olympus guide and Sweet Bonanza guide for the full mechanics of each, and our best Pragmatic Play slots guide for the complete comparison across all three.
If you're drawn to Big Bass Bonanza's collection-style bonus specifically, it's a mechanic that appears across a number of other fishing- and treasure-themed slots industry-wide, though we can only confirm this specific title's availability at Pantherbet among the casinos we track.
A common mistake is assuming the base game's fish symbols always carry a cash value — outside the free spins feature, most symbols pay according to a standard fixed paytable rather than a collected cash total, and the money-collection mechanic specifically applies during the bonus round. Another mistake is misunderstanding what triggers a retrigger — it's landing additional scatter symbols during the feature itself, not simply landing more fish or money symbols, that extends the round with extra spins.
A third common mistake, relevant specifically to Pantherbet's welcome package, is depositing the full intended bankroll on the first visit and missing out on the Big Bass Bonanza tier entirely — since that tier only unlocks with a third separate deposit, spreading deposits across the structure the operator has designed is the only way to claim all three tiers of free spins. And as with any slot, judging the game's overall generosity from a single bonus round — whether it retriggered heavily or ended early — isn't a reliable read on the underlying math, since retrigger frequency and money symbol values vary randomly round to round.
The retrigger mechanic in Big Bass Bonanza's bonus round can make a feature feel like it's always "about to extend again," which is exactly the kind of design that calls for a firm session budget set in advance rather than an open-ended one. Decide what you're comfortable losing before you start playing, treat it as entertainment spend, and use your casino's deposit or session limit tools if you find a bonus round pulling you past your planned budget.
