Big Bass Hold & Spinner Megaways is the 10th entry in the series and easily one of the most ambitious. Pragmatic Play and Reel Kingdom combine two proven mechanics — a Hold & Spin respin bonus and Big Time Gaming’s Megaways engine.
The result is a slot with up to 147,456 ways to win and a 20,000x maximum payout, comfortably the highest ceiling in the Big Bass catalogue.
For players already familiar with the series, that headline number is the main attraction.
In this review, we break down the RTP, volatility, both bonus features, and the real payout potential to see whether the added complexity actually improves the game.
What is the Big Bass Hold & Spinner Megaways Slot?
Big Bass Hold & Spinner Megaways is a high-volatility slot from Pragmatic Play and Reel Kingdom, released on 28 August 2023. It runs on Big Time Gaming’s Megaways engine, using six reels with a variable layout that expands to 147,456 ways to win.
The top RTP setting is 96.70%, and the maximum win is capped at 20,000x your bet, the highest ceiling in the Big Bass series.
Mechanically, this is one of the most feature-heavy Big Bass games. It combines Megaways tumbles, Mystery symbols, Fish Money symbols collected during Free Spins, and a Hold & Spin respin bonus triggered by Coin Money symbols. The grid can also unlock three additional top rows, increasing the number of ways on each spin.
Two feature buys are available: Free Spins for 100x the bet and Hold & Spin for 120x. Overall, it is the most complex and feature-dense entry the Big Bass franchise has produced so far.
Big Bass Hold & Spinner Megaways Graphics and Theme
Big Bass Hold & Spinner Megaways sticks closely to the series’ usual visual style. The setting is a bright underwater scene with bubbles drifting between the reels, fish moving in the background, and reeds and lily pads along the surface. It is a lighter, daytime look compared to darker entries like Mission Fishin'.
Symbol design follows the familiar Big Bass formula: a fishing float, rod, tackle box, dragonfly, and fish as the main paying symbols, with card royals covering the low end.
The Fisherman Wild appears during free spins, unchanged from earlier games. Above the main six-reel grid sits a separate three-row top reel section, clearly split from the base grid below.
The presentation is clean and functional. Anyone who has played a Big Bass slot will recognise the layout immediately.
The soundtrack is upbeat and fishing-themed without standing out much. It stays in the background and does not become irritating over long sessions.
Animations are simple, but the Tumble mechanic keeps the reels moving and stops the screen from feeling static during quiet base game stretches.

RTP (Return to Player)
Big Bass Hold & Spinner Megaways has a top RTP of 96.70%, slightly above the industry baseline of around 96% and higher than most Big Bass titles.
Like most Pragmatic Play slots, the game runs in multiple RTP configurations: 96.70%, 95.69%, and 94.62%, depending on the casino. The good news is that the version you can play here on Gamdom uses the highest RTP setting.
Volatility
The Big Bass Hold & Spinner Megaways slot is rated at maximum volatility, 5 out of 5. The base game hit frequency is roughly 1 in 5 spins, or about 20%, which is actually better than many high-volatility slots.
Min/Max Bet
At Gamdom Casino, the Big Bass Hold & Spinner Megaways slot runs from a minimum of $0.20 per spin up to $250.00 per spin. The minimum is slightly higher than many Pragmatic Play titles, which commonly start at $0.10, reflecting the more complex Megaways mechanics.
At $0.20 minimum, a Buy Free Spins purchase costs $20, and a Buy Hold & Spin costs $24, which makes these accessible even at lower stakes.
At the $250 maximum, a Free Spins buy is $25,000 and Hold & Spin is $30,000, strictly for high-roller territory. Keep in mind, these figures are specific to Gamdom Casino and may differ on other platforms.
Maximum Win
The Big Bass Hold & Spinner Megaways slot carries a 20,000x maximum win, double that of most other Big Bass titles, including Big Bass Splash and Big Bass Mission Fishin' (both 5,000x).
In cash terms, that is $5,000,000 at the $250 maximum bet, or $4,000 at the minimum $0.20 bet. The 20,000x ceiling is accessible in the base game, during Free Spins, and during the Hold & Spin bonus, and the round ends immediately once it is reached.
Big Bass Hold & Spinner Megaways Slot Features, Paylines, and More
Symbols and Paylines
Big Bass Hold & Spinner Megaways uses the Megaways system, so traditional paylines are replaced by ways to win across adjacent reels.
With all top rows unlocked, the grid can reach 147,456 ways, though the exact number varies with each spin based on the reel layout.
Wins pay left to right, starting from the first reel. Most combinations require three matching symbols, while the top symbol — the fishing float — pays from two of a kind and reaches 50x for six.
The dragonfly and fishing rod follow as the next highest-value regular symbols. Fish Money symbols also count as standard paying symbols and carry cash values.
Card royals (10, J, Q, K, A) sit at the bottom of the table, returning 0.10x to 1.50x for six of a kind. On their own, they rarely matter, but they can extend Tumble chains when the grid starts cascading.
Wilds
The Wild in Big Bass Hold & Spinner Megaways is a fishing net symbol, and it only appears on the top horizontal row above the main reels.
It substitutes for all regular paying symbols but not for Scatters, Fisherman Wilds, or Coin Money symbols.
Because it exists only on the top row, its impact depends on whether those rows are unlocked on the spin. If the top rows are locked, the Wild cannot appear. When they are active, a landing net can connect with multiple combinations across the expanded Megaways grid.
It is a more restricted Wild than usual, but when it does appear in an active top row, it can contribute to a much larger number of winning ways than a typical payline Wild.
Scatters
The Scatter in the Big Bass Hold & Spinner Megaways slot is a leaping fish symbol that appears across all reels. Landing three or more Scatters anywhere on the screen during a base game spin triggers the Free Spins feature.
Three Scatters award 10 free spins, four award 15, five award 20, and six award 25. The Scatter does not carry a direct cash value, its function is purely to unlock the bonus.
Landing Scatters during the Free Spins round does not retrigger the feature; retriggering is instead handled by the Fisherman mechanic described below.
Fish Money Symbol
The Fish Money symbol is one of the core engines of the Big Bass Hold & Spinner Megaways slot. These symbols land with a random cash value attached, drawn from a preset range: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 5,000x the total bet.
In the base game, they behave as regular symbols for the purposes of winning combinations and are removed by the Tumble mechanic when they contribute to a win. Their cash values cannot be claimed in the base game.
During Free Spins, they do not explode on wins but instead fall to the bottom of the screen as tumbles occur, where they wait to be collected by the Fisherman Wild. A 5,000x Fish Money symbol collected during a late-stage multiplier spin is the primary route to the game's maximum win potential.
Mystery Symbols
The Mystery symbol, depicted as a glowing lantern, adds an element of variance management to both the base game and Free Spins.
In the base game, all Mystery symbols that land on the same spin reveal themselves as the same paying symbol. These can potentially fill the rows with a high-value match, thus generating significant ways-to-win combinations that would not otherwise appear.
In Free Spins, the mechanic works differently. If a spin contains only Fisherman symbols with no Fish Money symbols present, Mystery symbols can randomly appear and reveal as any symbol.
This acts as a partial substitute for fish collection in otherwise dry free spins, giving the round more opportunities to generate meaningful values even when the primary collection mechanic is quiet.
Coin Money Symbol
The Coin Money symbol is a gold coin that triggers the Hold & Spin bonus. It appears on all reels except the topmost row, and each spin it lands on it carries a random value between 1x and 30x the total bet.
A Diamond Money symbol also appears during the Hold & Spin, carrying a value between 50x and 2,000x the total bet. These are the premium symbols of the respin round, and landing even one significantly elevates the bonus outcome.
The Hold & Spin is the simpler and more contained of the two bonus features. This makes it the lower-variance option for players who want more predictable bonus outcomes.
Free Spins
The Free Spins feature is the primary source of the Big Bass Hold & Spinner Megaways slot's biggest wins. During the bonus, the Fisherman symbol appears on all reels except the topmost row.
Each time a Fisherman lands on the same spin as Fish Money symbols, he collects all the cash values from those fish and accumulates them in a running total.
Importantly, all Fishermen that land throughout the entire round continue collecting. So, the more Fishermen that land across all spins, the more values are gathered.
Every fourth Fisherman collected retriggers the feature for 10 additional free spins and applies a multiplier to all future Fish Money collections. The first retrigger sets the multiplier to 2x, the second to 3x, the third to 10x, and every subsequent retrigger adds a further 10x with no upper limit.
This is the key differentiator from most Big Bass free spins rounds: the multiplier growth is unlimited. A fourth or fifth retrigger with a 20x or 30x multiplier collecting multiple 5,000x fish symbols in a single spin, is how truly exceptional outcomes happen in this game.
The feature plays out after the previous batch of spins ends, so retriggered spins stack rather than interrupt. If a spin has only Fishermen but no Fish Money symbols, a dynamite animation can randomly produce fish symbols from nowhere.
Hold & Spin Bonus
The Hold & Spin feature triggers when three or more Coin Money symbols land on the same spin.
Once activated, the grid freezes at the same size as the triggering spin. All other symbols disappear, and only Coin Money symbols or blanks can land. The feature starts with three respins.
Unlike most hold-and-win games, the coins here do not lock in place. When new Coin Money symbols land, the values of all visible coins are added to the total, after which the coins disappear, and the respins continue with a fresh grid.
This design allows the same positions to generate value repeatedly, rather than filling the grid and stalling the bonus.
The feature guarantees a minimum win of 20x the bet. If that threshold has not been reached when respins run out, the game awards three additional respins. Diamond Money symbols, worth 50x to 2,000x, can also appear during the bonus round.
Top Tips for Playing Big Bass Hold & Spinner Megaways
Test the Big Bass Hold & Spinner Megaways Slot in Demo Mode
The Big Bass Hold & Spinner Megaways slot is notably more complex than standard entries in the series. The unlockable top rows, Tumble mechanic, two bonus features, and the Fisherman collection system all interact at the same time.
On paper, the rules are straightforward, but the way they combine is easier to understand by actually watching the game play out.
Before risking real money, run the demo for 50–100 spins. Focus on how the top rows change the ways-to-win count, and watch how Tumble chains build from a single base-game win.
Getting a feel for that Megaways rhythm makes the real-money session much easier to manage.
Know When to Pay for a Bonus Feature
Two Buy Feature options exist in the Big Bass Hold & Spinner Megaways slot: Buy Free Spins at 100x the bet and Buy Hold & Spin at 120x.
The Free Spins option is the higher-variance choice but offers the route to the game's largest wins due to the unlimited multiplier potential. The Hold & Spin buy is the safer route if you want a more contained, predictable bonus experience.
What matters is context. Buying into the Free Spins at a $5 bet ($500 cost) and landing a first-level retrigger with a 2x multiplier will likely not break even.
This feature pays well when Fishermen accumulate quickly, and retriggering happens multiple times. That is statistically rare. Buy features make most sense when they represent a modest fraction of your session budget, not a significant portion of it.
Plan Your Budget and Stick to It
Despite its 20% base game hit frequency being better than many of its peers, the Big Bass Hold & Spinner Megaways slot can still drain a bankroll steadily in the base game.
Small Tumble chain wins at 0.2x to 2x your bet happen relatively often, but these rarely offset the cost of spinning at any meaningful stake.
The free spins trigger rate of 1 in 319 spins means variance over a typical session is substantial. A reasonable starting point is to enter with 150 to 200 spins worth of budget. At $1.00 per spin, that means $150 to $200 reserved purely for this slot.
Decide your stop-loss before you begin. The base game's activity can create a false sense of momentum; more frequent small returns do not reduce the long-term risk of a losing session.
