Boat Bonanza Colossal Catch Slot Review
Play’n GO have built a recognisable style across their portfolio with fishing-themed releases, and Boat Bonanza Colossal Catch continues that tradition with a refined approach to volatility balance. Released in August 2023 as a follow-on from the original Boat Bonanza, this sequel simplifies the mechanic landscape whilst introducing the distinctive Colossal Catch feature. The game delivers medium-paced gameplay rather than the high-intensity action of competitors like Big Bass Bonanza and Fishin’ Frenzy, positioning itself as an accessible entry point for those seeking a more relaxed fishing experience.
Base Game & Features
Boat Bonanza Colossal Catch operates on a 5-reel, 4-row grid with 12 fixed paylines. The game uses a straightforward win-from-left-to-right mechanic, requiring three or more matching symbols to form winning combinations. The theoretical RTP sits at 96.20% with a minimum bet of 0.10 and maximum stake of 50 per spin, providing flexibility across different betting profiles. The hit frequency averages 1 in 4 spins, supporting regular small-to-medium wins that maintain engagement without extended dry spells.
The symbol set comprises standard card values (Ace, King, Queen, Jack, Ten) forming the lower-paying tier, whilst themed symbols—the Seagull, Can of Worms, Harpoon, and Anchor—deliver higher payouts. Notably, the game features no traditional wild symbols, instead relying on the Catch and Colossal Catch mechanics as its primary win-enhancing feature.

The Catch Feature
Two fishing boats activate randomly on base game spins, positioned above the reels. These boats collect Catch symbols that land directly below them, with each Catch symbol carrying a random value between 1x and 50x the total bet. Values accumulate automatically, creating a secondary win path alongside the standard payline wins. This mechanic ensures base game engagement, as players remain invested across every spin waiting for Catch symbol combinations.
Colossal Catch Feature
The distinguishing feature triggers when both boats align above the same reel. When this occurs, all Catch symbols across all five reels are collected simultaneously and added to the total win, creating the game’s largest base game payouts. This mechanic replaces the Boat Multipliers and Respins system from the original Boat Bonanza, simplifying gameplay whilst maintaining excitement. The maximum win cap sits at 3,000x stake, representing a decrease from the original game’s 5,000x ceiling.

Boat Bonanza Colossal Catch Free Spins
Landing three or more scatter symbols across the reels triggers the Free Spins round, awarding 10 initial free spins. Landing four scatters provides a bonus payout of 20x the bet, whilst landing five scatters delivers 100x the bet bonus. Free Spins feature a mechanically distinct setup from the base game: both boats become permanently active on every spin, guaranteeing Catch symbol collection throughout the round.

The Swordfish Multiplier System
During Free Spins, the Swordfish symbol appears exclusively, collecting only through boats positioned directly above its reel. Each Swordfish collected increases the Colossal Catch Multiplier level. Three Swordfish symbols are required to advance to the next multiplier tier, with the maximum multiplier reaching 25x. Each multiplier level progression awards an additional 8 free spins, except the final level which grants 2 extra spins. This escalation system means the maximum free spins achievable during a round reaches 30, though reaching this threshold requires consistent Swordfish collection throughout the sequence.
Our Honest Verdict
Boat Bonanza Colossal Catch delivers a measured fishing-themed experience that prioritises accessibility over spectacle. The medium volatility positioning clearly differentiates this from high-intensity competitors, offering a jolly fishing trip when the ocean was calm. Both Boat Bonanza titles shouldn’t be marked down for their laid-back appearance or straightforward gameplay; this design philosophy serves a specific player segment well. For casual players seeking consistent engagement without extended dry spells, the game succeeds. The 96.20% RTP and 25% hit frequency create a rhythm of regular wins punctuated by feature opportunities, making sessions feel rewarding rather than gruelling.
The reduced maximum win (3,000x versus 5,000x in the original) does represent a lower ceiling for explosive payouts, which won’t satisfy players chasing massive multipliers. The feature replacement from Boat Multipliers and Respins to Colossal Catch, whilst simpler mechanically, still offers meaningful win potential during free spins through the Swordfish multiplier system. The route-one formula comparison to the original is fair—this is recognisably a Boat Bonanza game rather than a groundbreaking departure. However, the free spins both boats permanent mechanic and multiplier escalation provide sufficient depth for engaged play across repeated sessions.
Boat Bonanza Colossal Catch is a trip worth taking at least once, particularly if you appreciate the fishing aesthetic without demanding white-knuckle volatility. The game’s strength lies in its simplicity and balance. It will more than suffice for franchise enthusiasts and players seeking a peaceful slot experience, though those new to the Boat Bonanza series might find similar mechanics elsewhere in Play’n GO’s broader catalogue. This is an accessible, reliable entry point rather than an innovative standout—solid in execution and pleasant in tone, just not revolutionary.
