Big Bass Bonanza Megaways slot takes everything that made the original work and drops it onto a much larger playing field, adding up to 46,656 ways to win and a Tumble mechanic that keeps base game chains alive.
Mechanically, it is one of the most complete versions of the core Big Bass formula. The 4,000x maximum win, however, is likely to raise a few eyebrows for a Megaways slot.
This review breaks down what the game actually offers — and whether those trade-offs make it worth playing.
What Is the Big Bass Bonanza Megaways Slot?
Big Bass Bonanza Megaways is a video slot developed by Reel Kingdom and released through Pragmatic Play in November 2021.
It is the third entry in the Big Bass series, following the original Big Bass Bonanza and Bigger Bass Bonanza, and the first to use Big Time Gaming’s licensed Megaways engine. The game runs on six reels with a variable row layout, producing up to 46,656 ways to win.
The core numbers are solid: 96.72% RTP, maximum volatility rated 5/5, and a 4,000x maximum win cap.
Megaways introduces a tumble mechanic. Winning symbols disappear, new ones fall from above, and cascades continue until no new wins form.
The free spins round keeps the Fisherman Wild collection system from the original game, with up to three retriggers and multipliers that climb from 2x to 3x and eventually 10x.
Two extra modifiers appear during the bonus: Dynamite and Bazooka, both designed to help dead spins recover. Unlike later Big Bass releases, there is no bonus buy option here.
Big Bass Bonanza Megaways Graphics and Theme
The visuals return to the original Big Bass Bonanza style. The reels sit underwater in clear blue water, with rising bubbles separating the columns and fish drifting in the background.
Above the surface, you can see a bright sky, and the overall colour palette stays warm and light. It is familiar and easy on the eye, even if it does not try to reinvent anything.
Symbol design sticks to the usual fishing gear: a float, rod, dragonfly, and tackle box as the premium symbols, with card ranks covering the low end. Fish symbols double as Money symbols and are visually distinct, which helps when tracking them across the Megaways grid.
The Fisherman Wild appears only in free spins, and the collection animation (along with the Dynamite and Bazooka sequences) provides the most memorable moments in the game.
The soundtrack keeps the reggae-style tune from the original Big Bass Bonanza. It fits the relaxed theme, though it can feel repetitive over longer sessions.
Despite the variable Megaways layout, the grid stays visually clean. Symbol sizes change every spin, but the reels never feel cluttered.

RTP (Return to Player)
The Big Bass Bonanza Megaways slot carries an RTP of 96.72%, which is higher than average. This is even higher than many other Pragmatic products, including the original Big Bass Bonanza (96.71%).
Volatility
High volatility at 5/5 (on Pragmatic Play's own scale) means most of the game's return is concentrated in the free spins feature rather than spread across base game spins.
The Tumble feature provides more base game activity than a standard payline slot — chains can generate multiple wins from a single spin — but you should still expect stretches without significant returns between features.
Min/Max Bet
At Gamdom, the Big Bass Bonanza Megaways slot runs from $0.20 per spin up to $500.00. The minimum is higher than most Big Bass entries because all wins are multiplied by the total bet rather than per-line, which is standard for Megaways titles.
Maximum Win
The Big Bass Bonanza Megaways slot caps out at 4,000x your total bet. At the $500.00 maximum stake on Gamdom, that is a theoretical maximum win of $2,000,000.
Big Bass Bonanza Megaways Slot Features, Paylines, and More
Symbols and Paylines
Big Bass Bonanza Megaways uses a Megaways ways-to-win system rather than fixed paylines. Wins land when three or more matching symbols appear on adjacent reels from left to right.
The number of winning ways changes every spin depending on how many symbols land per reel, with a maximum of 46,656 ways when the grid is fully expanded.
The float is the top premium symbol, followed by the fishing rod, dragonfly, and tackle box. Fish symbols pay as regular symbols in the base game, but also carry Money values.
Card ranks cover the low end. Because Megaways calculates wins from the total bet rather than per line, premium symbol payouts appear larger than in the original Big Bass Bonanza.
Wilds
The Wild symbol in Big Bass Bonanza Megaways appears exclusively on the horizontal top reel in the base game and on all reels during free spins. It substitutes for all regular paying symbols but cannot replace the Scatter, Fisherman, or Money fish symbols.
In the base game, its appearance on the horizontal reel can form wins with symbols on the reels directly below it.
In free spins, the Fisherman takes over as the collector Wild, and the standard Wild's role shifts to a supporting substitution function. The Fisherman Wild, when it lands during free spins, collects all visible Money fish values from anywhere on the screen simultaneously.
Scatters
The Scatter symbol is a leaping bass fish, in line with the rest of the Big Bass series. Landing three, four, five, or six Scatters anywhere on the reels triggers free spins, awarding 10, 15, 20, or 25 spins, respectively.
The six-Scatter tier is specific to the Megaways layout and reflects the larger grid. Scatters can appear on any reel.
Unlike some later Big Bass releases, there is no assist mechanic here. If three Scatters do not land naturally, there are no respins, hooks, or near-miss triggers to force the feature.
Tumble Feature
The Tumble feature activates after every winning spin in both the base game and free spins. All symbols that form part of a winning combination disappear from the reels, and the remaining symbols fall to the bottom while new ones drop in from above to fill empty positions.
If the new configuration produces another win, the process repeats. Tumble chains continue until no new wins form. All wins from a chain are added together before being paid.
This mechanic is inherent to the Megaways engine and adds meaningful base game activity — a single triggering spin can generate several consecutive wins without any additional cost.
In free spins, Fish Money symbols behave differently: instead of disappearing as part of the Tumble, they fall to the bottom of the screen and remain in place, staying visible to be collected by the Fisherman Wild.
Money Symbols
Fish symbols on the reels serve a dual function. In the base game, they can form standard winning combinations as regular paying symbols. They also carry randomly assigned cash values on every spin, visible on the symbol.
Possible values are 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 4,000x total bet. In the base game, fish symbols explode and tumble as normal when they form wins.
In free spins, they do not explode. Instead, they fall to the bottom of the grid and accumulate there, remaining visible for the Fisherman to collect. This makes a full grid of fish during a free spins tumble chain a particularly valuable outcome, as multiple high-value fish can sit waiting to be collected on the next spin.
Free Spins Feature
The free spins round is where most of the slot’s value sits. During the feature, the Fisherman Wild can appear on any reel and collects the value of every visible Money fish on the screen.
If multiple Fishermen land on the same spin, each one collects the full total independently, which can produce large single-spin payouts.
Fisherman symbols are tracked on a meter beside the reels. Every fourth Fisherman retriggers the feature with 10 extra spins and increases the multiplier applied to future Money collections.
Level 2 activates a 2x multiplier, Level 3 raises it to 3x, and Level 4 jumps to 10x. After the third retrigger, the feature cannot extend further.
Two modifiers can also activate to rescue otherwise dead spins. Dynamite adds Money fish symbols when Fishermen appear without fish on screen.
Bazooka replaces all non-Fisherman symbols when Fishermen land, but no fish are present. Both mechanics exist to give quiet bonus spins a chance to recover.
Top Tips for Playing Big Bass Bonanza Megaways
Test the Big Bass Bonanza Megaways Slot in Demo Mode
The Megaways engine and Tumble mechanic make this feel very different from the standard payline Big Bass games, even in the base game. The grid expands and contracts each spin, and Tumble chains can produce several consecutive wins from a single spin.
If you are used to fixed grids, it can take a few sessions to adjust. Spending time in demo mode helps you understand how the cascades behave, how wins form across the wider grid, and how the Fisherman, Dynamite, and Bazooka mechanics actually play out in the bonus round.
Plan Your Budget and Stick to It
Big Bass Bonanza Megaways does not include a bonus buy. The only way into the feature is by landing Scatters naturally, so your bankroll has to cover the base game while you wait for the trigger.
In practice, that also removes the temptation to burn through funds on repeated feature buys, which became common in later Big Bass releases.
A sensible baseline is budgeting around 100 to 150 spins at your chosen stake. At $0.20 per spin, that means roughly $20–$30 before expecting the feature to appear. At $1.00 per spin, a $100–$150 session budget is more realistic.
Know When to Increase or Decrease Your Bet
Without a bonus buy, your bet size becomes the main lever for managing both session length and potential payouts.
Because the Tumble mechanic can produce several consecutive wins from a single spin, the stake you are playing at during those cascades matters more than in a standard slot.
A sensible approach is to stick to a stake you are comfortable losing across multiple dead spins rather than increasing bets while waiting for a feature that has no fixed trigger point.
If you hit a strong bonus round, dropping your stake afterwards is a simple way to extend the session and protect your winnings. There is no mechanical advantage to increasing your bet after a feature lands.

Recommended Games if You Liked the Big Bass Bonanza Megaways Slot
- Big Bass Bonanza (Pragmatic Play): The original that started the series. A 5x3 grid with 10 fixed paylines, a simpler structure, and a 2,100x max win. If the Megaways grid feels too large or the absence of a buy option frustrates you, the original offers the same collector mechanic in a more compact format. Good for understanding the base formula before exploring the expanded versions.
- Big Bass Splash (Pragmatic Play): A later series entry with a 5,000x max win, a bonus buy, and pre-round modifiers that Big Bass Bonanza Megaways does not have. If the 4,000x ceiling on Megaways felt limiting, Splash offers more upside with the same core collection mechanic on a standard 5x3 grid.
- Sweet Bonanza (Pragmatic Play): Another Pragmatic Play cascade slot, but with scatter pays rather than paylines, a tumble mechanic, and a 21,000x maximum win. A good option if you enjoyed the chain-win dynamic of the Tumble feature in Big Bass Bonanza Megaways, but want significantly more upside potential and more active base gameplay.
