Play Big Bass Bonanza Slot

Big Bass Bonanza is one of the most popular online slots in the UK regulated market. Released by Pragmatic Play in December 2020 in collaboration with Reel Kingdom, the original Big Bass Bonanza slot kicked off what has become one of the largest slot franchises in modern iGaming history, with more than 15 sequels and spinoffs released across the past five years.

The Big Bass Bonanza online slot plays out across 5 reels and 3 rows with 10 fixed paylines. Set beneath the surface of a still blue lake, the visuals capture the calm anticipation of casting a line and waiting for a big catch. The reels feature fishing-themed symbols including rods, tackle boxes, dragonflies and various fish, plus the all-important Fisherman Wild and the Fish Money symbols that drive the bonus round.

What made Big Bass Bonanza an instant UK favourite is the deceptively simple gameplay loop. The base game pays out clean line wins against a competitive 96.71% RTP, while the Free Spins round shifts the entire game into a money collection mechanic that gradually builds multipliers up to 10x with each set of four Fisherman Wilds collected.

Steps to Play the Big Bass Bonanza Base Game

1. Set your stake using the plus and minus buttons beneath the reels. Big Bass Bonanza accepts bets from £0.10 up to £250 per spin.
2. Press the spin button to start each round. The 5x3 grid lands fresh symbol combinations every spin.

4. Use Autoplay if you want to set a number of automatic spins, with optional loss and win limit settings to keep yourself in control.

Big Bass Bonanza features a familiar fishing-themed symbol set built around clearly tiered payouts. The top-paying symbols are themed around the fishing trip itself, while the lower-paying symbols use classic playing card royals.

Premium Symbols

The top-tier paying symbols on the Big Bass Bonanza slot are the fishing float, the fishing rod, the dragonfly, and the tackle box. These deliver the biggest base game line wins and are the symbols you want stacking up on the reels during the Free Spins round.

Card Royal Symbols

The standard A, K, Q, J and 10 card royals fill out the lower-paying tier. These appear more frequently than the premium symbols and help keep the base game flowing between bigger wins.

The Fisherman Wild

The Fisherman is the Big Bass Bonanza slot's Wild symbol. He substitutes for every other symbol on the reels except the Scatter, helping complete winning combinations across the 10 paylines. The Fisherman is also the key to the bonus round, where he collects the values from any Fish Money symbols on the reels.

The Fishing Boat Scatter

The Fishing Boat is the Scatter symbol. Three or more Fishing Boats anywhere on the reels trigger the Big Bass Bonanza Free Spins bonus.

Big Bass Bonanza Slot Paytable

All payouts shown are multipliers of the line bet, not the total stake.

The Big Bass Bonanza slot keeps its bonus mechanics focused on one central feature: the Free Spins round and its layered collection mechanics. The result is a bonus that builds tension across multiple stages without overcomplicating the gameplay.

Free Spins Feature

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

• 3 Fishing Boat scatters: 10 free spins
• 4 Fishing Boat scatters: 15 free spins
• 5 Fishing Boat scatters: 20 free spins

The bonus round triggers approximately once every 113 spins on average across long-term play.

Fish Money Symbols

Fish Money symbols are the key to the biggest payouts on the Big Bass Bonanza slot. These appear during the Free Spins round, each one displaying a cash value attached to the symbol. The values range from 2x your stake up to 50x your stake per individual fish.

Fisherman Wild Collection Mechanic

When a Fisherman Wild lands anywhere on the reels during the Free Spins round, he automatically collects every Fish Money symbol value currently on screen. If multiple Fisherman Wilds land on the same spin, they each collect the full Fish Money total together. This is where the biggest single-spin payouts come from, often delivering hundreds of times your stake when the timing is right.

Multiplier Progression Meter

The Big Bass Bonanza slot tracks every Fisherman Wild that lands during the Free Spins round in a meter at the top of the screen. Every fourth Fisherman collected triggers two effects at the same time:

• A multiplier upgrade applied to all future Fish Money collections during the round.
• +10 additional free spins added to your remaining count.

The multiplier progression goes through three stages: 2x → 3x → 10x. Reaching the 10x stage at 12 Fisherman Wilds collected is where the maximum 2,100x stake payout becomes possible.

Random Dynamite Feature

The Big Bass Bonanza slot also includes a random Dynamite feature that can trigger on any spin where exactly one Fisherman Wild lands. When triggered, the dynamite transforms several random symbols on the reels into Fish Money symbols, giving you extra collection potential for that spin and any retriggers that follow.

About the Big Bass Bonanza Slot Series

The original Big Bass Bonanza slot is the foundation of one of the largest slot franchises in modern iGaming. Pragmatic Play, in collaboration with Reel Kingdom, has released more than 15 follow-up titles since the original December 2020 debut, making the Big Bass series one of the most prolific slot franchises in the UK regulated market.

The Direct Sequels

The first direct sequel was Bigger Bass Bonanza, released in September 2021. Reel Kingdom led the development and stepped the format up to 5 reels with 12 paylines, raised the max win to 4,000x your stake, and added a random Bazooka feature that adds extra Fish Money symbols to the reels. Big Bass Bonanza Megaways followed in November 2021, applying the licensed Big Time Gaming Megaways engine to offer up to 46,656 ways to win per spin with the same Fisherman Wild collection mechanic.

The Big Bass Splash Branch

Big Bass Splash introduced new modifiers to the Free Spins round including stacked Wilds and Mystery Fish symbols. The Splash branch has since spawned Big Bass Halloween and Big Bass Halloween 2 (October 2024), the latter featuring a horror twist with dead bass, infected bugs and a chainsaw-wielding fisherman. Both deliver up to 5,000x your stake in max win.

Themed Spinoffs

Pragmatic Play has experimented with themed spinoffs across the Big Bass franchise too. Bigger Bass Blizzard wraps the format in snow for a winter aesthetic. Club Tropicana sends the fisherman to a tropical cocktail bar. Big Bass Day at the Races combines fishing slot mechanics with a horse racing theme. Big Bass Secrets of the Golden Lake layers on an Arthurian Legend twist, while Big Bass Xmas Xtreme sets the action in Antarctica with the fisherman ice-fishing through Christmas.

High-Stakes Versions

For players who want bigger max wins, Big Bass Bonanza Keeping it Reel (October 2022) raised the cap to 10,000x your stake. Big Bass Amazon Xtreme matches that ceiling, while Big Bass Bonanza 1000 pushes things further still with a 20,000x maximum win for the highest-volatility version in the series so far.

The Latest Releases

Recent additions to the franchise include Big Bass Bonanza Reel Action (May 2024) and the Big Bass Bonanza 3 Reeler (December 2024), the first title in the series to drop the format down to a compact 3-reel, 5-payline layout while keeping the core Fisherman Wild collection mechanic intact.

Smooth Spins typically carries the most popular Big Bass slots in our lobby alongside the original, giving you the full franchise to explore once you have got the hang of the base Big Bass Bonanza game.

Big Bass Bonanza keeps its mechanics straightforward, making it a recognisable choice for those who prefer a structured slot experience. Bigger Bass Bonanza expands on the original with increased multipliers and a larger reel setup. Fishin’ Frenzy sticks to a classic format with a focus on symbol collection, keeping gameplay clear and easy to follow. Big Bass Splash introduces added modifiers that adjust the free spins round, offering slight variations while staying true to the fishing theme.
