Released in November 2020, Big Bass Bonanza spawned an entire franchise. There are now over 20 titles carrying the Big Bass name, every one of them built around the same core idea. To understand why the original holds up alongside its sequels — and where it falls short — you need to understand exactly what it does with a 5×3 grid and one deceptively simple mechanic.
Base Game: What You’re Actually Playing For
The 5×3 grid runs 10 fixed paylines, pays left to right from reel 1, and needs at least three matching symbols to form a win. Standard setup, nothing unusual. The symbols divide into low-pay card suits (10, J, Q, K, A) and fishing-themed highs: tackle box, fishing rod, hat, and the golden fish, which is the most valuable regular symbol at 750× stake for five of a kind.

Two special symbols carry the game. The Fisherman is the wild — he substitutes for everything except the scatter bass fish, and landing him in the base game completes standard payline wins. His real job, though, is in the bonus. The scatter bass fish, when it appears, does nothing in the base game except count toward the free spins trigger threshold.
There are also Money Fish symbols scattered across the reels during both the base game and free spins. These green fish each carry a printed cash value — anywhere from fractions of your stake to multiples of it. The catch: in the base game, those values are entirely decorative. You can watch a 15× value fish sit on the grid for the whole spin and collect nothing. Money Fish only pay out when a Fisherman Wild lands on the same spin and hoovers up every visible fish value on the board simultaneously. That gap between “fish visible” and “fish collectible” is where most of the game’s tension lives.
Free Spins: How the Collect Mechanic Works
Three or more scatter bass fish trigger the feature. Three gets you 10 spins, four gets 15, five gets 20. Once inside, the rules shift meaningfully. Money Fish now appear more frequently and with higher printed values. Every time a Fisherman Wild lands on any reel, he instantly collects the combined total of every Money Fish visible on the grid at that moment — not just those on his payline, every single one in view.
Here’s what that means practically. Say three Money Fish are visible on a free spin showing values of 4×, 7×, and 12× your stake. A Fisherman Wild lands on reel 3. He collects all three simultaneously, awarding 23× stake from a single symbol landing. No payline alignment needed. The collection pays directly on top of any regular wins that same spin also produces.
This is why the free spins feel structurally different from most bonus rounds. You are not building wins from symbol combinations — you are waiting for the fisherman to arrive and sweep up whatever fish values have accumulated on the board. Spins with no Fisherman contribute nothing. Spins where three Fishermen land across five or six visible Money Fish at meaningful values are where the session-defining moments happen.
The bonus triggers every 120–150 spins on average, which is reasonably frequent for a high-volatility title. You will not be grinding 400 spins between features as a routine experience the way you might with a 5/5 volatility slot.
Retriggers and Multipliers
Landing three or more scatter bass fish during free spins awards five additional spins. More importantly, every fourth Fisherman Wild collected during the feature activates a permanent multiplier on all subsequent spins in that round.
The multiplier ladder runs: collect 4 Fishermen → 2× multiplier active. Collect 8 total → 3× multiplier. Collect 12 total → 10× multiplier. That 10× is applied to every Money Fish collection and every payline win for the remainder of the bonus. A late-stage collection of three fish worth 5×, 8×, and 14× stake under the 10× multiplier pays 270× stake from a single symbol landing.
Reaching the 10× tier requires collecting 12 Fishermen during a single bonus round. In practice, this demands retriggers — getting there in an initial allocation of 10 spins is mathematically possible but uncommon. Sessions that retrigger twice or more and accumulate 12+ Fishermen are where the 2,100× maximum lives. Most bonus rounds end well short of that, typically returning between 15× and 80× stake, which is why the max win probability sits at roughly 1 in 3.8 million spins.
Pros and Cons
- RTP of 96.71% is one of the highest default figures among Pragmatic Play’s catalogue and comfortably above the industry 96% average. This matters over any meaningful session length.
- Collect mechanic is genuinely intuitive — unlike cluster pays or Megaways multiplier stacking, you can read a Big Bass Bonanza bonus round at a glance. Fish values add up, fisherman collects them, total is paid. New players understand it within two spins.
- Feature triggers every 120–150 spins on average — medium-high volatility rather than extreme, meaning bankrolls of moderate size can expect to see the bonus within a reasonable session rather than chasing it indefinitely.
- Multiplier retrigger structure creates escalating stakes — the 2× → 3× → 10× ladder gives the bonus a narrative shape. Sessions that climb the ladder feel earned rather than random, which is part of why the franchise has sustained popularity since 2020.
- Franchise depth — if you enjoy the core collect mechanic, 20+ variants explore it in different ways: Megaways grids, Hold & Spinner bonuses, Amazon jungle settings, Vegas aesthetics. The original is the easiest entry point into an extensive catalogue.
- Max win of 2,100× is modest for a high-volatility slot — the ceiling ranks among the lower ones in Pragmatic’s own library. Gates of Olympus caps at 5,000×, Sweet Bonanza at 21,100×. Players chasing life-changing numbers should look elsewhere; this slot is built for sessions where 50–200× bonuses are the realistic ambition.
- RTP operator flexibility is wider than comfortable — the gap between 96.71% and 94.02% is significant, and not all casinos disclose which version is deployed without you checking the in-game info panel manually. A 2.7% difference in RTP changes expected session losses meaningfully over time.
- Base game contribution is largely cosmetic — Money Fish values sit visible on the reels for entire spins without paying. For players who prefer every spin to feel consequential, the base game can feel like waiting time between bonuses rather than gameplay in its own right.
- No bonus buy option in the original — unlike many Pragmatic titles, the original Big Bass Bonanza does not offer a direct bonus purchase. If you want bonus-buy access to the collect mechanic, you need one of the later series entries (Bigger Bass Bonanza and others added it).
About Pragmatic Play
Pragmatic Play was founded in 2015 in Malta and operates as one of the largest multi-product content providers in the iGaming industry, supplying slots, live casino, bingo, and virtual sports to thousands of operators globally under a single API integration. Their slots catalogue runs to 300+ titles, with roughly five new releases per month maintained consistently since 2018.
Big Bass Bonanza was developed under the Reel Kingdom label, a studio that works in close collaboration with Pragmatic Play and whose titles are distributed exclusively through the Pragmatic platform. Reel Kingdom originated the collect mechanic that defines the Big Bass series, applying it across the expanding franchise while Pragmatic handles distribution and operator relationships.
One practical note that applies across the entire Pragmatic/Reel Kingdom catalogue: the company offers operators multiple RTP configurations for the same game. This is standard industry practice, but Pragmatic’s floor (as low as 94% on some titles) is lower than many premium studios. Opening the information panel and noting the active RTP setting before any real-money session is a 30-second habit worth developing at any casino in Canada running their games.
FAQ
The printed values on Money Fish in the base game are not decorative mistakes — they create anticipation and signal potential. When a Fisherman Wild does land in the base game, he collects all visible Money Fish values exactly as he does in free spins. Base-game Fisherman collections are relatively rare and typically smaller in scale than feature collections, but they do happen and provide the only meaningful base-game wins beyond standard payline hits. The primary purpose of showing the values at all times is to build session tension: watching three high-value fish sit uncollected for several spins before a Fisherman lands is the game’s core emotional loop, condensed into the base game as a preview of what the bonus delivers at scale.
Yes, but the ceiling without retriggers is much lower. A standard 10-spin bonus with no retriggers limits your total Fisherman collections and makes reaching the 3× or 10× multiplier tier mathematically unlikely. Most solid-but-unremarkable bonus rounds — the kind that return 30–60× stake — achieve that purely on the quality of Money Fish values present during initial spins, with one or two Fisherman collections landing at the right moment. Retriggers matter because they increase your total spin count and your chance of accumulating enough Fishermen to climb the multiplier ladder. The 2,100× maximum requires reaching the 10× tier, which in practice means collecting 12+ Fishermen — something that almost exclusively happens in extended, retriggered bonus rounds.
The original is the cleanest introduction to the mechanic: 10 paylines, straightforward collect structure, no additional layers. Bigger Bass Bonanza (2021) adds a random Bazooka feature that drops extra Money Fish mid-bonus, increasing volatility and raising the max win to 4,000×. Big Bass Bonanza Megaways (2021) puts the same collect mechanic on a 6-reel Megaways grid with up to 46,656 ways to win and a 4,000× ceiling. Big Bass Splash (2022) extends the feature with a progressive scatter respin, and later entries add Hold & Spinner rounds, mission-based modifiers, and themed variants. Start with the original to understand the mechanic, then move to Bigger Bass Bonanza or Megaways for more win potential, or Big Bass Splash if you prefer longer-running bonus rounds. The RTP on the original (96.71%) remains among the highest in the series.
