Play Big Bass Vegas Double Down Deluxe Slot Game

Big Bass Vegas Double Down Deluxe is one of the most innovative slots in Pragmatic Play and Reel Kingdom's expanding Big Bass franchise. Released on 12 September 2024, the Big Bass Vegas Double Down Deluxe slot replaces the traditional Big Bass lakeside setting with neon-lit Las Vegas, layering the iconic Strip skyline above an aquatic grid below.

The Big Bass Vegas Double Down Deluxe slot introduces a genuine first to the Big Bass series: two separate Fisherman Wild characters (a Red Fisherman and a Blue Fisherman), each with their own dedicated multiplier upgrade trail. This dual collector system is what gives the game its "Double Down" name and what sets it apart from the rest of the franchise. Every four Wilds of the same colour fill the corresponding meter, awarding +10 extra Free Spins and upgrading that colour's multiplier from 1x to 2x to 3x to a maximum of 10x.

Set across a 5x3 grid with 10 fixed paylines, the Big Bass Vegas Double Down Deluxe slot delivers very high volatility gameplay (rated 5 out of 5 on the volatility scale) with a 5,000x stake maximum win. Below we cover everything you need to know about playing the Big Bass Vegas Double Down Deluxe slot at Smooth Spins.

The Big Bass Vegas Double Down Deluxe slot splits its visual layout between two contrasting environments. Above the reels, a neon-lit Las Vegas Strip skyline at night plays out behind the title bar, with towering resorts, hotels, and the iconic Vegas neon palette. Below the reels, the action moves underwater into an aquatic grid where the fish symbols swim into view. The split background creates a deliberately playful "Vegas underwater" aesthetic that no other Big Bass slot has used.

All symbols on the Big Bass Vegas Double Down Deluxe slot are designed in Pragmatic Play's signature cartoon format with solid lines and bright neon contrast. The premium symbols include a hot pink speedboat (the highest-paying icon), a flamingo, fishing rod, money stack, and the regular fish group symbols. Card royals (10, J, Q, K, A) fill the lower-paying tier, all rendered in glowing neon colours that match the Vegas theme.

Reel activity includes effects like Hook pulls, Dynamite explosions, and Bazooka symbol shifts, all triggered during specific Free Spins sequences. The upbeat showy soundtrack matches the glitzy palette, leaning into the Vegas glamour and shifting tone during the bonus round to amplify the dual fisherman collection action.

The Big Bass Vegas Double Down Deluxe slot uses a tiered symbol structure with the pink speedboat as the top-paying premium symbol. The neon Vegas card royals fill the lower-paying tier. The Wild symbols and Money symbols only become active during the Free Spins round.

Premium Symbols

The top-paying symbols on the Big Bass Vegas Double Down Deluxe slot are themed around the Vegas + fishing crossover concept:

• Pink Speedboat (highest-paying premium, pays from 2 of a kind)
• Flamingo
• Fishing Rod
• Money Stack
• Fish Group

The pink speedboat is the only premium symbol that pays for as few as two of a kind on consecutive reels from left to right.

Card Royal Symbols

The standard 10, J, Q, K and A card royals fill out the lower-paying tier on the Big Bass Vegas Double Down Deluxe slot. All five are rendered in glowing neon colours to match the Vegas aesthetic.

Dual Fisherman Wild Symbols

The Big Bass Vegas Double Down Deluxe slot features two separate Fisherman Wild symbols (a Red Fisherman and a Blue Fisherman), both of which only appear during the Free Spins round. Both substitute for all paying symbols (but not for Scatters or Money symbols) and both feed their own dedicated multiplier upgrade meter.

Vegas Bass Scatter Symbol

The Scatter symbol is the Vegas Bass, which can land on any reel. Three or more Vegas Bass Scatters anywhere on the reels trigger the Free Spins round. Even with only 2 scatters in view, the Scatter Nudge mechanic can sometimes nudge in a third scatter from a reel above to trigger the bonus.

Fish Money Symbols

Fish Money symbols carry fixed multiplier values ranging from 2x up to 5,000x your stake. They appear during the Free Spins round only and are collected exclusively by the Red and Blue Fisherman Wilds when they land on the reels.

Big Bass Vegas Double Down Deluxe Paytable

The Big Bass Vegas Double Down Deluxe slot is built around the most layered Free Spins system in the entire Big Bass franchise. The Dual Fisherman Wild collector mechanic, the Double Down meters, the random Dynamite/Hook/Bazooka features, and the persistent multiplier upgrades all combine to give Big Bass Vegas Double Down Deluxe more depth than any earlier Big Bass slot.

Free Spins Feature

Land three or more Vegas Bass Scatter symbols anywhere on the reels to trigger the Big Bass Vegas Double Down Deluxe Free Spins round. The number of free spins awarded scales with the number of Scatters that land:

• 3 Vegas Bass scatters: 15 free spins (higher than original Big Bass Bonanza's 10)
• 4 Vegas Bass scatters: 20 free spins
• 5 Vegas Bass scatters: 25 free spins

Even when only 2 scatters land, the Scatter Nudge mechanic can sometimes nudge a third scatter into view from a reel above, awarding the Free Spins round.

Dual Fisherman Wild Collectors

The defining feature of the Big Bass Vegas Double Down Deluxe slot. Once Free Spins begin, the two Fisherman characters become active:

• Red Fisherman Wild substitutes for regular symbols and collects Money symbol values into the Red Meter.
• Blue Fisherman Wild substitutes for regular symbols and collects Money symbol values into the Blue Meter.

When a Fisherman of either colour lands alongside Money symbols on the reels, all their values are collected and paid out immediately. Multiple Fishermen of the same colour can stack together for combined collections on the same spin.

Double Down Meters and Retriggers

Every four Fisherman Wilds of the same colour fill that colour's Double Down Meter. When a meter is filled, two things happen simultaneously:

• +10 additional Free Spins are added to your remaining count.
• The multiplier for that colour upgrades through the progression.

The multiplier progression for each colour goes through three stages:

• First filled meter: 2x multiplier on that colour's Fish Money collections
• Second filled meter: 3x multiplier
• Third filled meter: 10x multiplier (maximum)

The two meters operate independently, so a player could reach 10x on Red while still on 2x on Blue, or any combination in between.

Random Dynamite, Hook and Bazooka Features

Three random features can trigger during the Free Spins round, each addressing a different gameplay scenario:

• Dynamite Feature: Triggers if a Fisherman Wild appears without any Fish Money symbols on the reels. The dynamite explodes and adds several random Money symbols to the reels for that spin.
• Hook Feature: Triggers if Fish Money symbols appear without any Fisherman Wild on the reels. The hook attempts to pull a random reel and reveal a Fisherman to collect the visible values.
• Bazooka Feature: Triggers if a Fisherman Wild appears without Fish Money symbols. The bazooka replaces all regular symbols (except Wilds and Scatters) with new symbols for that spin.

The Big Bass Vegas Double Down Deluxe slot operates on a 5x3 grid with 10 fixed paylines. Winning combinations are formed from left to right using standard reel logic, with matching symbols on consecutive reels starting from reel 1.

All symbols appear across clearly defined lines, with no dynamic modifiers in the base game. During regular spins, the Big Bass Vegas Double Down Deluxe slot uses a traditional setup without Wilds or multipliers (the Fisherman Wilds and Multiplier Meters only become active during the Free Spins round). The Free Spins round introduces all the additional mechanics including the dual collector features and the random Dynamite/Hook/Bazooka enhancements.

The base game hit frequency is approximately 1 in 7.7 spins, while the Free Spins round triggers roughly once every 113 spins on average. The maximum 5,000x stake payout is achieved roughly once in every 2,544,391 spins. There are no cascading effects or shifting reels in the Big Bass Vegas Double Down Deluxe slot, keeping the gameplay structure clean and easy to follow despite the depth of the Free Spins feature.

• Big Bass Christmas Bash combines classic fishing mechanics with festive visuals and seasonal Free Spins bonuses. 
• Big Bass Hold Spinner includes a Hold and Spin feature alongside traditional fish collection mechanics. 
• Big Bass Xmas Extreme introduces advanced multipliers and additional features within a winter themed slot environment. 

The Big Bass Vegas Double Down Deluxe slot game delivers an unusual combination of themes while keeping its core mechanics aligned with the fishing series. Pragmatic Play introduces new visual contrast without changing the underlying structure too drastically. Double meters and coloured retriggers provide variation during Free Spins, while random enhancements offer some unpredictability within a contained format. This version remains consistent with other titles in the series, offering long gaps between major wins due to its high volatility. The slot fits best for players already familiar with this feature style and is well represented in the wider Smooth Spins Casino lineup.
