Up to 147,456 Ways to Win | 20,000x Maximum Payout
Every spin generates between 324 and 147,456 ways to win. Winning symbols explode and tumble, with new symbols cascading down for consecutive wins from a single spin. The dynamic reel grid changes height each spin, with 2-6 symbols appearing per reel plus three bonus rows above reels 2-5.
Land 3 or more coin money symbols to trigger Hold & Spin with 3 respins. Every new coin that lands resets the counter back to 3. Coins display values from 1x to 2000x your bet. Diamond symbols award mega prizes from 50x to 2000x. Minimum win guaranteed at 20x bet.
3+ scatter symbols award 10-25 free spins. During the feature, fisherman symbols collect all fish money values on screen. Every 4th fisherman retriggers the feature with +10 spins and increasing multipliers: x2, x3, x10, then +x10 for each subsequent retrigger with no limit.
This isn't your typical fishing slot. Pragmatic Play and Reel Kingdom have combined three of the most player-friendly mechanics into one high-volatility package: the Megaways engine licensed from Big Time Gaming, the proven Big Bass fisherman collection system, and the popular Hold & Spin respin feature. The result is a slot that offers multiple routes to the 20,000x maximum win.
The Megaways system means the number of ways to win changes dramatically with every spin. You might get a modest 1,728 ways on one spin, then 147,456 ways on the next. This variability is key to the game's appeal - any spin could explode into a massive grid with maximum win potential.
After every winning combination, those symbols disappear and remaining symbols tumble down to fill the gaps. New symbols cascade from above, potentially creating new wins. This continues until no new winning combinations form. During a hot streak, a single spin can generate five, ten, or even more consecutive tumbles, with wins accumulating throughout.
What makes this implementation interesting: the reel structure stays fixed at its initial size throughout the tumble sequence. If you started with 6 symbols on reel 1, it stays at 6 symbols as new ones drop in. This consistency means your ways to win remain stable during the tumble chain.
When you land 3 or more coin money symbols anywhere on the grid, the Hold & Spin bonus launches. Those triggering coins lock in place while empty positions spin independently. You start with 3 respins. Each time a new coin or diamond lands, it sticks and the respin counter resets to 3.
The clever bit: there's a guaranteed minimum win of 20x your total bet. If respins expire and you haven't reached that threshold, the game awards 3 more respins. This continues until you hit at least 20x, ensuring the feature never disappoints completely.
Coin values range from 1x to 2000x your bet. Diamond symbols are rarer but award premium values between 50x and 2000x. Fill the entire grid and you're looking at a serious payday - potentially thousands of times your stake if high-value symbols dominate.
Pro tip: You can buy direct entry to Hold & Spin for 120x your bet, or free spins for 100x bet. At maximum £250 stake, that's £30,000 for instant Hold & Spin access - only for high rollers with deep pockets and strong nerves.
Landing 3, 4, 5, or 6 scatter symbols triggers 10, 15, 20, or 25 free spins respectively. This is where the Big Bass DNA really shines. During free spins, fish money symbols can land showing values from 2x to 5000x your bet. These don't pay immediately - they need to be collected.
That's where the fisherman comes in. When a fisherman symbol lands, he collects the values of all fish money symbols currently on screen. Those values get added to your total win. The game counts every fisherman that lands during the feature.
Here's the escalation mechanic: every 4th fisherman collected retriggers the feature with 10 additional spins and applies a multiplier to future fish collections:
This creates genuine escalation potential. If you keep retriggering and collecting fishermen, multipliers can reach x50, x100, or theoretically unlimited values. The 5000x fish combined with high multipliers is how players reach the 20,000x maximum win.
There's even a dynamite feature: if you land only fisherman symbols with no fish money on screen, a random dynamite animation can trigger, adding fish money symbols to random positions so the fisherman has something to collect.
The highest-paying regular symbol is the bass fish itself, awarding £100 for six of a kind at a £2 bet (50x). The tackle box pays £10 for six (5x), whilst the fishing rod, dragonfly, and reel pay progressively less. Card symbols 10 through A fill out the lower pays at 1x to 1.5x for a full way.
Wild symbols appear only in the top bonus row above the main grid, substituting for all symbols except scatters, fishermen, and money symbols. The top row spins independently from right to left and can lock or unlock randomly - when locked, those positions don't spin, and locked wilds can persist for multiple spins.
The 96.70% RTP sits well above the 96% industry standard and matches across base game and both buy features. This is the full RTP version - some operators may offer lower configurations, so always check before playing.
The 5/5 volatility rating means extremely high variance. You'll experience lengthy dry spells punctuated by occasional significant wins. Base game hits tend to be modest, with the real money concentrated in the bonus features. This suits patient players who can weather 50-100+ dead spins waiting for a bonus to land.
Typical sessions will see you grinding through base game spins with small tumble wins keeping you afloat, then spiking dramatically when Hold & Spin or free spins trigger. The free spins feature offers the highest win potential due to the unlimited multiplier escalation, but Hold & Spin provides more consistent value with its guaranteed minimum.
Big Bass Hold & Spinner Megaways combines proven mechanics into a feature-rich package that offers multiple paths to significant wins. The Megaways tumble system provides base game engagement, Hold & Spin delivers guaranteed value with respin excitement, and the free spins fisherman collection system creates those viral big win moments that players chase.
At 96.70% RTP and 5/5 volatility, it's mathematically fair but emotionally draining. You need patience and bankroll management. The £0.20 minimum bet makes it accessible, whilst the £250 maximum and 20,000x potential means genuinely life-changing wins are possible for high stakes players.
If you enjoyed previous Big Bass slots but wanted more features and win potential, this Megaways version delivers. If you're new to the series, start with the demo to understand how the fisherman collection system works - it's the key to unlocking the slot's maximum potential.
