Hell of a Fishing Trip!
Zombie fishermen trapped in a bait shop surrounded by the undead. Cast your line into murky waters where rotting fish carry massive cash prizes up to 3,333x your stake. This isn't your typical fishing trip.
Every spin brings you closer to the zombie horde's hidden treasures
Two distinct Wild Fisherman symbols (blue and red) appear during Free Spins. Each collects all zombie fish Money symbols on screen. Track them separately on dual metres – every 4th Wild of each colour awards 10 extra spins and increases the multiplier.
Decayed fish carry random cash values from 2x to 5,000x your total bet. These undead catches only pay out when a Wild Fisherman lands to collect them during the Free Spins feature. The more Wilds you accumulate, the higher the multiplier.
Land 3, 4, or 5 Scatter symbols to trigger 15, 20, or 25 Free Spins. Collect Wild Fishermen to retrigger with escalating multipliers: 2x after first retrigger, 3x after second, and a massive 10x after the third. Maximum volatility meets maximum rewards.
When 2 Scatters land without the third, random features activate. Scatters may shift down one position whilst other reels respin, or a hook pulls reels up to reveal that crucial third Scatter. These mechanics significantly increase feature hit frequency.
During Free Spins, if you've got fishermen but no fish, dynamite explodes to add fish Money symbols. If you've got fish but no collectors, a hook drags fishermen onto the screen. A shark can even transform all symbols except Wilds.
Bypass the base game entirely. Buy regular Free Spins for 100x your bet, or splash out 300x for Super Free Spins where you only need 3 Wilds total (not 4 per colour) to retrigger. Ante Bet mode (15x stake) increases natural Scatter frequency but disables buy options.
Pragmatic Play's Big Bass series has built a cult following amongst UK slots players, and this Halloween instalment delivers the franchise's signature collecting mechanic wrapped in genuine horror atmosphere. You're locked in a bait shop with glass doors barely holding back a zombie horde, casting into an aquarium filled with undead fish whilst blood-stained handprints smear the windows behind you.
This is where Big Bass Halloween III separates itself from standard fish-themed slots. During Free Spins, two types of Wild Fisherman appear – one in blue kit, one in bloodied red gear. When either lands, it hoovers up the cash values from every zombie fish Money symbol visible on that spin. Here's the crucial bit: blue and red Wilds are tracked on separate collection metres.
Every 4th Wild of each colour triggers a retrigger, awarding 10 additional Free Spins and bumping up the collection multiplier. The progression runs: 1x (base level) → 2x → 3x → 10x. That final jump to 10x is where the slot's 3,333x max win potential comes into play. You can progress both metres independently, potentially reaching 10x multipliers on both blue and red collectors in a single bonus round.
The zombie fish symbols are the money carriers. On every single spin – base game included – each fish is randomly assigned a multiplier value: 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, or 5,000x your total bet. These values are purely cosmetic in the base game; they only pay when collected by a Wild Fisherman during Free Spins.
At a £2 bet, for example, fish values range from £4 (2x) to £10,000 (5,000x). The 5,000x fish is exceptionally rare, but it's what makes those max win screenshots possible when combined with the 10x collector multiplier (50,000x theoretical if it weren't capped at 3,333x).
Unlike many slots where near-miss features are pure theatre, Big Bass Halloween III's mechanics genuinely affect outcomes. When exactly 2 Scatters land in the base game, two random events can occur:
These aren't guaranteed – they trigger randomly – but they're common enough to feel impactful. You'll see them activate roughly 30-40% of the time when you land 2 Scatters, which significantly boosts your Free Spins hit rate compared to a standard 3-Scatter trigger slot.
Once you're in Free Spins, three random events keep dead spins from killing momentum:
If you've got Wilds on screen but no fish, sticks of dynamite explode and plant fish Money symbols in random positions.
If you've got fish but no Wilds to collect them, a hook drags a reel upward, pulling fishermen symbols into view.
A shark swims across and transforms all non-Wild symbols into something else – usually used to convert low-value letters into premium symbols or more fish.
These modifiers don't trigger every spin, but they're weighted to activate when you need them most. It's Pragmatic's way of preventing the bonus from bricking completely when RNG deals a bad sequence.
You have three ways to play:
Maths: At £2 base bet, Ante Bet costs £3 per spin. Buying regular Free Spins costs £200. Buying Super Free Spins costs £600. The RTP is 96.50% across all modes, meaning the buy features are priced fairly relative to natural triggers, but they obviously drain your balance faster if the bonus doesn't deliver.
This is a 5/5 volatility slot. That rating isn't decorative. In 100 spins at £2 stake (£200 invested), you might trigger Free Spins twice, win £80 total, and walk away down £120. Or you might hit one bonus at 600x (£1,200) and be up £1,000. The swings are violent.
The base game is deliberately dry. You'll land 3-of-a-kind letter wins for £1-£2 frequently, but premium symbol combinations are rare. The game wants you in Free Spins, where all the real money is. If you're playing with a £100 balance, expect it to fluctuate between £50 and £150 for long stretches before a bonus either rescues you or puts you deep into profit.
Big Bass Halloween III works because it combines proven mathematics (the Big Bass collecting system has paid out millions across the series) with a theme that's executed properly, not just slapped on. The zombie apocalypse bait shop setting is coherent. The blood-splattered fishermen, decayed fish, and barbed wire number symbols all fit. It's not a generic Halloween skin.
For UK players specifically, the slot's available at all major UKGC-licensed casinos. The RTP is locked at 96.50% – there's no lower RTP version being pushed to UK operators like some Pragmatic titles. And the £0.10 to £375 bet range accommodates both casual £0.20 spinners and high rollers chasing that £125k max win (3,333x at £375 stake).
Play Responsibly: Big Bass Halloween III is a high volatility slot. The maximum win is capped at 3,333x your bet. When you reach this cap, the feature ends immediately and remaining spins are forfeited. Set deposit limits before you play.
