Big Bass Halloween 3 is a spooky fishing slot from Reel Kingdom, launched in October 2025 and built on a 5-reel, 3-row grid with 10 fixed paylines. There is no progressive jackpot here, but the game caps out at a solid 5,000x your stake, wrapped in very high volatility and a default 96.5% RTP. In this Big Bass Halloween 3 slot review, I will walk through how the features, maths profile, and horror reskin of the classic Big Bass formula actually play out in practice, so you can decide if this is your kind of seasonal grind or one to skip.



Big Bass Halloween 3 runs on a tight 5-reel, 3-row setup with 10 fixed paylines. Nothing fancy in terms of layout; it is the classic Big Bass grid wearing a Halloween mask. The betting range is broad enough for most players, starting at £0.10 per spin and reaching £250, or £375 if you switch on the Ante Bet. The coin value adjusts automatically based on your stake, so you never have to fiddle with extra settings.
The slot game uses a 96.5% RTP by default, which is slightly above average, though casinos can run lower versions at 95.5% or 94.5%. The volatility is on the extreme end, so the balance will sway a bit until the bonus decides to show up. As for top-end potential, the max win is capped at 5,000x your stake. There is no jackpot layered on top: everything comes from the features, multipliers, and sheer luck during the Free Spins round.
Big Bass Halloween 3 is available at some of the top online casinos in the UK right now. Here are the best slot sites hosting the game:



Reel Kingdom went full Halloween this time around, and the slot wears it proudly. The backdrop is a dark swamp lit by a sickly full moon, with fog drifting across the water and pumpkins glowing along the reel frame. It feels like a fishing trip someone organised after watching a late-night zombie marathon. The soundtrack sits in that sweet spot between eerie and playful, with rattles, distant croaks, and the odd horror sting. It works well because the Big Bass formula is still light-hearted under all the gloom.
The paytable mixes the usual fishing gear with spooky twists. Your low symbols are 10, J, Q, K, and A. They handle the filler wins and pay between 5x and 10x for five-of-a-kind. Premiums include the lure, the backpack, the axe, and the van, with the van sitting at the top at 200x for a full line. Fish symbols also act as Money Symbols and take random values up to 5,000x.
Wilds only appear in Free Spins, and this slot has two of them: the red zombie fisherman and the blue hunter fisherman. They step in for regular symbols and collect fish values. Scatters come in the form of spooky pumpkins, and landing three or more starts the bonus round.

Big Bass Halloween 3 is built on modern HTML5 tech, so it behaves exactly as you expect from a recent Reel Kingdom release. The interface snaps into place on smaller screens, the buttons stay large enough to tap without squinting, and the reels sit comfortably in the centre. The controls collapse neatly into a compact menu, so you have space to follow the action without your thumbs covering half the lake.
The animations hold up well on phones and tablets, and nothing feels cramped, even during the busier moments in Free Spins. It is a clean, mobile-first experience from top to bottom.



The slot packs a handful of features, most of them centred around the Free Spins round. The Fishermen Wilds, Money Symbols, random modifiers, and dual multiplier trails all come together there, so the bonus is the only place where things can actually escalate.
The game does include an Ante Bet and a Feature Buy, though most players will treat those as optional boosters rather than features in their own right. Below is a breakdown of each mechanic.
You trigger Free Spins by landing three, four, or five pumpkin Scatters, which award 15, 20, or 25 spins. This is the core of the slot and the only phase where serious wins can happen. The round introduces the blue and red Fishermen, who serve as Wilds and collectors. Whenever they appear with fish on the reels, they scoop up the values and feed their respective meters.
Filling a meter with four fishermen retriggers +10 spins and upgrades its multiplier from 1x to 2x, 3x, and eventually 10x. Random events like dynamite, hook pulls, and the shark transform to help keep the round alive, especially during dry stretches.
You can hit values up to 5,000x if the fish cooperate, which could be pretty hard most of the time.

Fish symbols double as Money Symbols, appearing with random cash values ranging from 2x to 5,000x your stake. These values do nothing in the base game. They only come into play during Free Spins, where the Fishermen Wilds collect them. If you hit a spin packed with high-value fish and both wilds show up, the round can escalate quickly.
The blue and red Fishermen only appear during Free Spins. They act as standard Wilds and collect Money Symbol values on sight. After they collect, they are sucked into their meters at the top. Each meter has its own multiplier track, so upgrading both can give you a rare double-engine setup where big fish get multiplied twice within the same feature.
Three random modifiers step in during the bonus. The dynamite drop adds fish symbols when wilds appear without anything to collect. The hook pull drags in one or more Fishermen when fish symbols land alone.
The shark transform changes all symbols except the fishermen into fish, which can be the nudge you need to turn a dead spin into a big payout. These modifiers do not guarantee huge wins, but they do help bridge the gaps.
The Ante Bet increases your stake by 50% and bumps the scatter frequency, making the Free Spins trigger a little more reachable. It does not change the maths in a dramatic way, but if you are the impatient type, it smooths out the wait.
Now, if for any reason you are playing from outside the UK, you can buy straight into the action.
The standard buy costs 100x your bet and awards a normal Free Spins entry with at least three Scatters. The Super Free Spins option costs 300x and makes each retrigger require only three collected fishermen instead of four.
It is expensive (and not recommended for beginners at all), but players who enjoy the volatility often go straight for the super option.

I enjoyed this one more than I expected, given how saturated the Big Bass series has become.
The Halloween coat of paint feels oddly fitting for a slot that already thrives on chaos. The gloomy swamp, the zombie fisherman, the awkward mix of humour and horror … it all comes together in a way that makes the game feel a bit lighter than its volatility might suggest.
I have seen the dual-trail setup before, though, and that familiarity cuts both ways. It is reliable, but it no longer surprises. The 1-in-113 bonus hit rate softens the grind, and the modifiers do their best to keep the round afloat, but you still rely on the fisherman showing up at the right moment.
I walked away thinking it is fun for a seasonal run, but it is not a game I would park myself in for months.
I settled on a six because Big Bass Halloween 3 does everything competently but leaves little to get excited about. The theme is fresh enough, the animations are neat, and the numbers are reasonable.
Yet, the base game is thin, the formula is well-worn, and the most interesting parts sit behind a bonus round that may or may not cooperate. The Halloween twist gives it personality, but underneath that, it is basically Big Bass running through a haunted house with a coat of fake blood.
