Something Wicked This Way Swims
Plunge into the darkest depths where zombie bass lurk and the grim reaper fisherman haunts. Trigger free spins with wild collection, multipliers up to 10x, and a terrifying max win of 2,100x your stake.
During free spins, every fisherman wild that lands collects all money symbol values on screen. Stack up wilds to retrigger with increasing multipliers: 2x, 3x, then a massive 10x on the third retrigger.
Golden piranha-like fish carry random values from 2x up to a staggering 2,000x your bet. These appear on special reels during the bonus and can be randomly added when only 1 wild is on screen.
Rated maximum volatility with 5 out of 5 lightning bolts. Wins are infrequent but the potential for huge payouts in a short session is real. Perfect for players who prefer big swings over steady drips.
Can't wait for scatters? Purchase free spins instantly for 100x your total bet. Jump straight into the action where the real money is won with wilds collecting fish values.
Boost your scatter frequency by selecting the 1.5x ante bet multiplier. More scatters on the reels means more natural free spins triggers, though the bonus buy is disabled with this option active.
The round ends immediately if you hit the 2,100x total bet cap, whether in base game or free spins. All remaining features are forfeited, but you walk away with the maximum prize up to AUD $787,500 at max bet.
Big Bass Halloween is a 5-reel, 3-row video pokies machine with 10 fixed paylines, developed by Reel Kingdom exclusively for Pragmatic Play's platform. This Halloween horror twist on the popular Big Bass series takes the fishing theme underwater into a dark, eerie environment populated by zombie bass and overseen by a grim reaper fisherman.
Wins pay left to right on adjacent reels starting from the leftmost position. The life ring buoy is your top-paying regular symbol, awarding AUD $5,000 for five of a kind at a AUD $25 bet level. Following that are the fishing hook (AUD $2,500 for 5OAK), the sinister crow with glowing red eyes, and the blood-splattered tackle box (both paying AUD $1,250 for 5OAK).
Lower-value symbols are playing card ranks A, K, Q, J, and 10, each designed with a Frankenstein-style stitched aesthetic in different colours: purple ace, blue king, red queen, green jack, and golden ten. These card symbols all pay identically: AUD $250 for five, AUD $62.50 for four, and AUD $12.50 for three of a kind.
The key to big wins is the fish money symbol system. On every spin, fish symbols can land displaying random monetary values. These golden piranha-like fish on crimson backgrounds show multipliers of 2x, 5x, 10x, 15x, 20x, 25x, 50x, or an enormous 2,000x your total bet. However, in the base game these values sit dormant—they're only collected during the free spins feature when a fisherman wild lands.
Critical Rule: Fish money symbols only pay their values when collected by a wild symbol during free spins. In the base game, they're merely teasing what could be won in the bonus.
Land 3, 4, or 5 scatter symbols anywhere on the reels to trigger 10, 15, or 20 free spins respectively. The scatter is the zombie bass fish emblem—a green-skinned fish with exposed bones and a red "SCATTER" banner beneath it.
During free spins, the grim reaper fisherman appears as a wild symbol on all reels. Each wild substitutes for all symbols except scatters, but more importantly, each wild that lands collects all money symbol values currently visible on the screen. Multiple wilds on the same spin each collect the full value independently, meaning two wilds on a spin with AUD $500 worth of fish symbols awards AUD $1,000 total.
Here's where Big Bass Halloween separates itself from standard free spins pokies: every 4th wild symbol you collect during the feature retriggers the round, awarding 10 additional spins. But it gets better—each retrigger increases a multiplier applied to all subsequent money symbol collections:
After the third retrigger, you cannot retrigger again, but you're playing with a 10x multiplier on every fish collected, which can lead to massive wins especially if high-value 2,000x fish symbols appear.
Additionally, when only a single wild lands on a free spin, fish money symbols can randomly appear on empty positions at the end of that spin, giving you more values to collect on subsequent spins.
Big Bass Halloween offers two ways to increase your scatter frequency or skip straight to the action:
Ante Bet (1.5x): Activate the "Extra Chance of Scatters" feature from the left panel, which multiplies your total bet by 1.5x. This adds more scatter symbols to the reels, giving you a higher natural chance to trigger free spins. Note that the bonus buy feature is disabled when ante bet is active.
Buy Free Spins: Pay 100x your current total bet to instantly trigger the free spins bonus with 10 spins. At a AUD $2.50 bet this costs AUD $250, at AUD $25 bet it's AUD $2,500, and at the maximum AUD $250 bet you're paying AUD $25,000 to buy the feature. A confirmation screen with a blood-splattered wooden sign appears, giving you the option to decline (red X button) or accept (green tick button).
Bets range from AUD $0.10 to AUD $375. The minimum is 1 coin per line at AUD $0.01 coin value across 10 lines. Maximum is 10 coins per line at AUD $2.50 coin value, which totals AUD $250, or AUD $375 with the 1.5x ante bet multiplier active.
The maximum win is capped at 2,100x your total bet. If your cumulative win in any round reaches this cap, the round immediately ends, you're awarded the win up to 2,100x, and all remaining free spins or features are forfeited. At maximum bet of AUD $375, this cap represents AUD $787,500.
Player Strategy Tip: The maximum win cap applies to the total round win, not individual spin wins. During free spins with retriggered multipliers, it's possible to hit this cap rapidly if multiple high-value fish symbols are collected. Monitor your cumulative win counter during big bonus rounds.
All payouts below are based on a AUD $25 total bet (AUD $2.50 per line). Payouts scale proportionally with your bet level.
All five card symbols pay identically: AUD $250 for five of a kind, AUD $62.50 for four, and AUD $12.50 for three. These stitched, Frankenstein-style symbols appear in purple (A), blue (K), red (Q), green (J), and gold (10).
Wild (Fisherman): Appears only during free spins on all reels. Substitutes for all symbols except scatter. Collects all money symbol values on screen when landing.
Scatter (Zombie Bass): Triggers free spins when 3+ land anywhere. Awards 10, 15, or 20 free spins for 3, 4, or 5 scatters respectively.
Money Symbol (Golden Fish): Displays random values of 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x total bet. Only pays when collected by a wild during free spins.
Big Bass Halloween carries an RTP of 96.06% across all game modes—base game, ante bet, and bonus buy all maintain the same return to player percentage. This is slightly above the industry average of 95-96% and indicates a fair long-term return.
Volatility is rated at the maximum level: 5 out of 5 lightning bolts. In practical terms, this means you'll experience longer dry spells between wins, but when wins arrive—particularly during free spins with multipliers—they can be substantial. High volatility pokies suit players with larger bankrolls who can withstand variance and are chasing significant multiplier wins rather than frequent small payouts.
Hit frequency isn't explicitly stated, but player experience suggests approximately 1 in 4-5 spins return a win in the base game, with the majority being low-value card symbol combinations. Scatter frequency increases notably when the ante bet is active.
The visual design immerses you in a dark underwater Halloween environment. The background depicts a misty lake surface with silhouettes of dead, leafless trees and mountains against a dark blue-grey sky showing faint aurora effects. Below the waterline, the scene transitions to murky underwater depths in deep blue-green tones with seaweed silhouettes and bubble effects creating an eerie, haunted atmosphere.
The game logo features distressed horror-style green lettering for "BIG BASS" with zombie texture, and "HALLOWEEN" on a red blood-splatter banner. Two small zombie bass fish perch on either side of the logo at the top of the screen. The reels are separated by vertical chains of bubbles, enhancing the underwater aesthetic.
Symbol design is detailed and thematic: the crow has glowing red eyes and clutches a rabbit in its talons, the tackle box shows blood splatters and rust, the life ring has the "RK" Reel Kingdom branding, and the card symbols feature cross-stitching reminiscent of Frankenstein's monster. The fisherman wild is portrayed as a grim reaper figure in a dark hooded cloak with long beard and pale skin, wielding a fishing rod.
Audio design matches the spooky theme with ambient underwater sounds, eerie music during the base game, and intensifying tracks during free spins, particularly when wilds land and collect money symbols.
