Big Bass Halloween 3: Frightful Fishing in a Zombie Outbreak Slot

March 2, 2026

Ever wondered what fishing would be like in a zombie apocalypse? Well, Big Bass Halloween 3, played on PokerStars, takes the familiar Big Bass setup and gives it a spooky online casino overhaul for online slots fans.

The core of the experience stays easy to follow because wins pay left to right on adjacent reels from the leftmost reel, and the bigger moments come with the Free Spins feature, where Money values can be collected by the Wild Fisherman symbols and boosted through two separate meters.

Theme and Design: Big Bass Becomes a Horror

Instead of the usual calm fishing style, Big Bass Halloween 3 leans into a horror-fueled theme. The background styling is darker, with zombie hands seen pressing against the glass of a fishing cabin. Even one of the fisherman characters has become a zombie, although his love for fishing hasn’t died off yet.

This time, the large lake has been replaced by a small fish tank in the centre of the room, which is the only thing that hasn’t been trashed by the undead horde. Despite the appearance, this online slot is still recognisable as a Big Bass title, but the new Halloween presentation makes it feel a lot sharper, especially once the Free Spins feature starts stacking collectors and values on the screen.

When it comes to the soundscape of this online slot, it leans into the creepy aesthetic with mysterious 80s-style music that would fit well in the Dawn of the Dead movie. Beneath that are separate ambient noises that people would expect to hear during a zombie apocalypse, such as wailing cries and wind blowing through the fishing cabin.  

Core Gameplay: 10 Paylines with Spooky Symbols

All symbols pay left to right on adjacent reels starting from the leftmost reel, and only the highest win is paid per line. When wins land across multiple paylines, those wins are added together. Also, all wins are multiplied by the bet per line, with win values shown as coins, which keeps everything consistent across paylines and payout amounts.

Symbol Values

The paytable of this online casino game mixes classic card symbols, stitched together like flesh, along with a handful of larger horror-themed picture icons. At the top sits the camper van symbol, which pays £200.00 for five of a kind, £20.00 for four, £5.00 for three, and £0.50 for two (based on a £1.00 bet). Just below that, the blood-stained fishing lure pays £100.00 for five, £15.00 for four, and £3.00 for three. The next tier includes the axe and the survival backpack, and both follow the same payouts. Each one pays £50.00 for five, £10.00 for four, and £2.00 for three. The fish pile symbol pays £20.00 for five, £5.00 for four, and £1.00 for three.

​The lower end is handled by the card ranks. The A and K each pay £10.00 for five, £2.50 for four, and £0.20 for three. The Q, J, and 10 each pay £5.00 for five, £1.00 for four, and £0.20 for three. It is a straightforward ladder, with the bigger spikes coming with the premium icons, while the bonus mechanics are where the biggest moments happen.

Special Symbols: Wild Fisherman, Scatter, and Money Values

Big Bass Halloween 3 uses two Wild Fisherman symbols, shown as a blue zombie and a red fisherman trying to survive. These Wild Fisherman symbols appear on all reels during the Free Spins round and substitute for all symbols except the Scatter and the Money symbol.

The Scatter symbol is shown as a fish badge and it shows up on all reels. Landing three or more Scatter symbols triggers the Free Spins feature. The Money symbol is tied to the fish paying symbols, which are also Money symbols, and with every spin the fish take a random Money value. Those possible Money values are 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, or 5000x the total bet. This basically means that the fish can act as standard paying symbols in the base game, then carry a separate value layer that matters most once Free Spins is running and collectors are landing.

Free Spins Triggers

Hitting three Scatter symbols triggers the Free Spins feature and awards 15 free spins, four Scatters award 20 free spins, and five Scatters award 25 free spins. There’s also a built-in second-chance moment in the base game when two Scatters land without a third, as a random feature can bring an extra Scatter onto the screen. One option is a respin where, if the Scatters on the screen can move down one position without leaving the reel area, a respin is triggered. In that respin, the reels with Scatters move one position down and the reels without Scatters respin. The other option is a hook feature, where a hook can pull one of the reels up to reveal another Scatter.

Free Spins: Two Collectors and Two Meters

Once the Free Spins feature is triggered, the Wild Fisherman symbols take over as the core mechanic. During the Free Spins feature, each Wild Fisherman symbol collects all the values from Money symbols on the screen. Those Wild Fisherman symbols also feed two separate trackers. Blue and red Wild Fisherman symbols that hit during the round are collected separately on a blue or red meter, so progress is tracked by colour rather than being combined into one single ladder.

Each meter has its own retrigger pacing and its own multiplier progression. Every fourth Wild Fisherman symbol of a given colour collected in its connected meter retriggers the feature, awards 10 more free spins, and increases the multiplier for Money symbol collection with the Wild Fisherman of that colour. The multiplier increases to 2x for the second level, 3x for the third level, and 10x for the fourth level. After the fourth level on each meter, the feature can’t be retriggered anymore, so there’s only so far each track can climb. Having two meters ticking forward, with two chances of triggering Free Spins, makes the pacing feel quicker, especially when one type of fisherman symbol starts landing more often than the other.

End-of-Spin Events in Free Spins

This online slot also adds a few random end-of-spin events during Free Spins that are designed to keep the collector mechanic active, even if things didn’t land right during the actual feature. When there are fisherman symbols on the grid but no fish, there’s a chance that, at the end of a free spin, fish Money symbols can appear in random places using the dynamite spin feature.

When there are fish symbols on the screen but no fisherman, there’s a chance that, at the end of a free spin, a hook will show up to pull a random reel up to bring fisherman symbols onto the screen. There’s also a third random event for when there’s no fish, where an animated shark can appear at the end of a free spin to change all the symbols on the reels, except for fisherman symbols, to something else. This can help turn a near miss into a payout if the player is lucky after the shark does its work.

Ante Bet: Increasing Scatters at a Price

When playing on PokerStars, Big Bass Halloween 3 has an Ante Bet option, which increases the chance of hitting Scatter symbols. When activated, the RTP stays the same as the base game, at 94.50%, so the change comes with the pacing and mechanics of a session, instead of promising improved or more frequent payouts. The casino game also keeps its high volatility rating, which means it pays out less often on average, but there’s a chance for bigger hits in a short time span.

Final Thoughts: A Familiar Big Bass with a Darker Bonus Focus

Big Bass Halloween 3 keeps the base game rules simple and familiar, then puts the emphasis where Big Bass slots usually shine, which is the Free Spins feature. The collectors do the work, Money values set the targets, and the blue and red meters give the bonus round a sense of progression without making it feel complicated or frustrating. Add in the second-chance Scatter mechanic in the base game, plus the Dynamite, Hook and Shark events during Free Spins, the features are built to keep collector moments happening, even when the fish stop biting.
