Big Bass Halloween Online Slot Review

A hugely popular series of online casino games gets a horror-themed makeover in the Big Bass Halloween slot. It’s the work of Pragmatic Play and their partner studio Reel Kingdom and takes a humorous twist on the classic fishing theme.

Symbols include stitched together playing card emblems, a crow eating a dragonfly, and a murderous fisherman. They appear across 5 reels, and 3 rows of symbols, crossed by 10 paylines.

Features include free spins where the fisherman can reel in fish money prizes of up to 2,000x your stake from blood-soaked waters. The free games can retrigger, and fish values increase each time, to a maximum of 10x. 

Big Bass Halloween is a medium to high volatility game with generous returns of 96.04%. You can unleash the fearsome fisherman across desktop and mobile platforms at the best Slot Sites featured here.

How to Play the Big Bass Halloween Slot Machine

If you have played any of the others in the extensive Big Bass series, you’ll recognise many of the symbols, but the setting has now moved from a peaceful river to darker waters. The muted colours include a black fishing tackle box, life ring with a bite taken out of it, while the free-flying dragonfly from other games has come to a sticky end and is being picked apart by a red-eyed crow. 

Even some of the controls have a horror style. Otherwise, they are similar to those find across the Pragmatic Play / Reel Kingdom range that ensures ease of use on PCs, Android, iOS, and Windows mobiles on your chosen Betting Apps. Click the plus or minus tabs to the sides of the main Spin button to pick from the wide bet range of 0.10 to 250.00 per spin. 

A side bet of 50% extra improves the odds of entry to free spins and players can buy right into the feature for 100x the stake. Autoplay and Quick Spin options are also available.

The ‘I’ button below the reels opens the Big Bass Halloween slot paytable. You can see symbol values here, along with details on features such as free spins with fish money symbol collections and upgrades. This is a 10-line slot and in the base games, you win with matched symbols across line, starting on the left. 

Free Spins & Other Big Bass Halloween Slot Features

Like others in the range, most of the action in the Big Bass Halloween slot is held back for the free spins feature. Leaping bass in any 3, 4, or 5 places at once will award 10, 15, or 20 free spins in that order. 

Several things change here, as the evil, hook-swinging fisherman can now appear, substituting for others if he can then complete winning combinations. Fish money symbols in red waters pay line wins in the base games, but now the money values attached to them become available. Fish are worth 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x the total bet and any fisherman symbols landing at the same time will reel them in. If multiple fishermen are in view, each will collect all fish values for even greater rewards. Randomly, if the fisherman is in view, but no fish, a dynamite symbol brings fish onto the reels. 

A bonus trail also appears above the reels during the free spins. Fishermen collect on the trail, and you need to land 4 of them to retrigger the feature. Once the current spins have played out, you get 10 extra free games with fish money symbols doubled in value. You can retrigger the free spins twice more with 4 fishermen each time, and fish multipliers increase to 3x, then a maximum of 10x. Beyond this point you can’t retrigger the free games.

Big Bass Halloween Slot Maximum Wins, Volatility, & Average Returns

Maximum wins in any spin or over the course of the free games are 2,100x the stake, or 525,000.00 at the highest stake of 250.00. It’s rated at 4/5 on the Pragmatic Play scale of volatility and the Big Bass Halloween slot has long-term payback percentage of 96.06%.

Our Big Bass Halloween Slot Verdict

The horror theme is certainly played for laughs, so there’s nothing to fear from the Big Bass Halloween slot machine. The gameplay and features are identical to the standard version, so you get somewhat bland base games without even a wild symbol to help complete wins, combined with a fantastic free spins round. 

Once the free games begin you can win big prizes as the fisherman collects fish money values, and there’s the chance to retrigger the games over and over for greater rewards as multipliers become active. 

The maximum win is nothing special, at just 2,100x the stake, but it makes it a little more achievable as a result. If you want a fun change from the usual fishing-themed slot style, be sure to enjoy this killer game at the best Online Casino sites. 


Big Bass Halloween blends fishing and horror in a fun way. Symbols include playing card emblems held together with stitches, a crow eating a dragonfly, and a fisherman in black coat, wielding a big hook.

This is a 10 payline game, so there are 10 different ways to match symbols across the 5 reels and 3 rows of the Big Bass Halloween slot. Paylines start from the left reel, and you win from 3, 4, or 5 matched symbols on a line.

Trigger the Big Bass Halloween slot free spins feature and the murderous fisherman now appears. He’s a wild symbol who can act as others, and also collects the values of any fish money symbols in view at the same time. They can pay up to 2,000x the stake.
