About Big Bass Bonanza Megaways
Big Bass Bonanza Megaways is part of Pragmatic Play's popular fishing-themed slot series, released in November 2021. It takes the familiar Big Bass Bonanza formula — the Fisherman collector mechanic and cash-valued fish symbols — and supercharges it with the Megaways™ engine, adding tumbling wins and up to 46,656 ways to win per spin.
With high volatility and a maximum win of 4,000× your stake, the game is designed for players who enjoy chasing big bonus rounds and are comfortable with longer dry spells in the base game.

Big Bass Bonanza Megaways Overview
Built around a fishing theme, the game replaces the original's fixed 5-reel, 10-payline layout with 6 variable reels using the Megaways™ engine, licensed from Big Time Gaming. The number of symbols displayed on each reel changes with every spin, generating anywhere up to 46,656 ways to win. Wins pay left to right across consecutive reels — no fixed paylines.
The base game is deliberately straightforward to follow, keeping the focus on building toward Free Spins, where the Fisherman collector mechanic, progressive multipliers, and bonus modifiers all come together.
RTP and Volatility Explained
Big Bass Bonanza Megaways has a published RTP of 96.70%, though the game supports configurable RTP settings — individual UK operators can deploy it at a lower figure. A rate of 94.62% has appeared on some UK casino pages. Always check the RTP displayed in the in-game information panel before playing, as it reflects the actual version you're on.
The game is classified as high to highest volatility, meaning:
- Base game wins are infrequent; long stretches without meaningful returns are normal.
- Most payout potential sits inside the Free Spins feature, particularly at Stage 3 and Stage 4.
- Session results can swing sharply — a run of cold base game spins can be offset by a single strong bonus round.
For players managing their bankroll, smaller bet sizes can help extend playtime while waiting for Free Spins to trigger.
How Big Bass Bonanza Megaways Works
The Tumble feature activates after every winning spin. Winning symbols are removed, remaining symbols fall down to fill the gaps, and new symbols drop in from above. The game checks for new wins and repeats the process until no further winning combination forms. This can chain multiple consecutive payouts from a single spin.
Alongside standard symbols, the game includes three special mechanics:
- Wild – substitutes for regular symbols. Appears exclusively on the independent top-row positions of reels 2–5.
- Scatter – triggers the Free Spins round when three or more appear anywhere on the reels. Scatters do not tumble.
- Fisherman – the collector symbol, active only during Free Spins. When it lands, it collects the total value of all Money/Fish symbols currently visible on the reels.
Free Spins Feature
The Free Spins bonus activates when three or more Scatter symbols land on the reels.
- 3 Scatters – 10 Free Spins
- 4 Scatters – 15 Free Spins
- 5 Scatters – 20 Free Spins
- 6 Scatters – 25 Free Spins
During the feature, Money/Fish symbols stay on the reels rather than tumbling away, accumulating across spins. When a Fisherman lands, it collects the total value of all visible fish and pays it out instantly. The more fish on screen, and the higher their values, the bigger the collection payout.
Progressive Multiplier System
Free Spins are divided into four stages, each applying a multiplier to Fisherman collection payouts. Every fourth Fisherman collection advances the stage and awards an additional 10 Free Spins.
- Stage 1 – ×1
- Stage 2 – ×2
- Stage 3 – ×3
- Stage 4 – ×10
Reaching Stage 4 and landing collections under the ×10 multiplier is where the game's largest payouts originate. Getting there requires consistent Fisherman appearances — this is where the high volatility is most keenly felt.
Random Bonus Enhancements
Two modifiers can trigger during Free Spins, acting as rescue mechanics when the feature runs dry:
- Dynamite – adds Money/Fish symbols to random reel positions when Fishermen land with few or no fish to collect, manufacturing collection opportunities.
- Bazooka – clears all non-Fisherman symbols from the reels entirely, triggering a fresh cascade of new symbols that can set up a stronger position.
Both modifiers add unpredictability to the feature and can turn a slow-starting bonus into something more productive, though their appearance is not guaranteed.
Maximum Win Potential
Big Bass Bonanza Megaways offers a maximum theoretical win of 4,000× your total bet. At the highest UK stake of £5 per spin, this represents a potential payout of £20,000. If a Free Spins round hits the cap at any point, the feature ends immediately and remaining spins are forfeited. Compared to other Megaways titles — some of which advertise caps of 10,000× or higher — the 4,000× ceiling is a commonly noted limitation of the game.
Who Should Play Big Bass Bonanza Megaways
- Players who enjoy high-volatility slots where the bonus is the main event
- Fans of collector mechanics and building-toward-a-moment gameplay
- Players comfortable with tumbling reels and chained wins
- Megaways players looking for a familiar format with a fishing theme
Final Verdict
Big Bass Bonanza Megaways builds on the original Big Bass Bonanza formula with the added complexity of the Megaways engine, tumbling wins, and a four-stage multiplier ladder inside Free Spins. The mechanics are intuitive once learned, and the progressive stage system gives the bonus a goal-oriented feel that keeps it engaging across sessions.
For players who enjoy high-volatility gameplay and the satisfaction of watching fish accumulate before a Fisherman sweeps them up, it's a compelling slot — provided you're comfortable with variance, aware of the configurable RTP, and realistic about the 4,000× win cap.
Big Bass Bonanza Megaways is a game of chance. The theoretical RTP for this slot is up to 96.70%, though this may vary by operator.
