Gus Goes Fishin’ Slot Review
iSoftBet has established itself as a developer unafraid to revisit successful formats and refine them. Gus Goes Fishin’ sees the beloved character venture away from the mines into entirely new territory. Released in September 2023, this fishing-themed slot taps into a genre that has proven phenomenally successful in recent years—a market dominated by titles like Big Bass Bonanza. The question isn’t whether iSoftBet can deliver quality mechanics; it’s whether they’ve crafted something distinctive enough to stand out among established fishing slots.

Base Game & Features
Gus Goes Fishin’ operates on a familiar 5×3 grid with 20 paylines, a structure that feels comfortable without being uninspired. The fishing theme permeates every visual element—golden reels against a tropical backdrop with smooth animations throughout. iSoftBet wastes no time throwing players into the action with multiple Fishin’ Bonanza Modifiers that can trigger during base play.
The base game modifiers include three distinct options. Reel ‘Em In automatically collects all fish symbols on the reels. Big Catch delivers a random multiplier of 2x to 5x applied to any winning combination. Bonus Boost adds extra scatter symbols when two or more scatters are already in view, making bonus triggers feel more frequent than they might otherwise. These modifiers create meaningful variance in base gameplay, ensuring sessions don’t feel repetitive before the bonus round activates.
There’s also a Gold Coin Side Bet available for eligible players, which increases spin cost by 50% but boosts modifier activation frequency. The side bet lifts RTP from 96% to 96.01%—a modest improvement that reflects the additional feature triggering. The distinction matters for players weighing cost against feature engagement.
Bonus Features & Free Spins
The heart of Gus Goes Fishin’ lies in the Deep Spins bonus round, triggered by landing 3, 4, or 5 fishing boat scatter symbols. Land 3 scatters and you’ll receive 8 free spins; 4 scatters award 10 spins; 5 scatters deliver 12 spins. The scatter requirement feels balanced—achievable without feeling trivialised. During Deep Spins, a distinct underwater setting replaces the beach backdrop, signalling a shift in visual presentation that reinforces the thematic transition.
The Sticky Golden Fish symbol appears exclusively during Deep Spins and functions as a special wild with collected random values. Unlike standard wilds, the golden fish can be collected and held across spins, building a multiplier trail. Only one golden fish can remain on the reels at any given time during the bonus round, which tempers the feature’s potential without eliminating it entirely.
Central to bonus excitement is the Fish Collection Multiplier system. As players land symbols during Deep Spins, fish are collected progressively. Reaching 8 collected fish activates a 2x multiplier; 16 fish unlock 5x; achieving 24 fish triggers a 10x multiplier. This progression mechanic creates a secondary objective within free spins, maintaining engagement throughout the bonus window. The multiplier ladder feels achievable during a typical bonus round, avoiding the frustration of unrealistic collection targets.
Players can purchase bonus access directly via Bonus Buy options. The regular bonus buy costs 60x stake and awards a random 3, 4, or 5 scatter trigger with standard gameplay. The premium Golden Deep Spins Bonus Buy costs 200x stake but guarantees 5 scatters plus an immediate sticky golden fish symbol, skipping the ramp-up phase. The cost-to-value ratio differs substantially between options—the golden variant costs 3.3x more but delivers maximum spins and a bonus mechanic head start.

Our Honest Verdict
Gus Goes Fishin’ succeeds at what it sets out to accomplish: a competent fishing slot that combines recognisable mechanics with polished execution. The 96% base RTP with medium volatility positions it comfortably within the fishing slot landscape, particularly competing with titles like Big Bass Bonanza. The 5,840x maximum win sits squarely in the middle range—impressive without being exceptional for a game with this feature density.
What elevates the title is the balance between base game engagement and bonus focus. Many fishing slots delegate all fun to the bonus round, leaving base play feeling thin. Gus Goes Fishin’ avoids this trap through the Fishin’ Bonanza Modifiers, which trigger frequently enough that sessions feel varied before Deep Spins activates. The fish collection mechanic during free spins provides satisfying progression without dominating the experience.
The limitations are equally transparent. The sticky golden fish mechanic, whilst thematic, is restricted to a single instance per bonus round—a constraint that prevents the feature from becoming truly explosive. Players seeking mid-tier entertainment will find plenty to enjoy; those chasing high-volatility eruptions or six-figure win potential should look elsewhere. The game understands its lane and occupies it capably.
Overall Verdict: 7.5/10 – iSoftBet delivers a solid addition to the fishing slot genre that respects player time without demanding constant attention to bonus triggers. Recommended for those who appreciate medium volatility gameplay with thematic polish.
