Golden Fish Tank 2 Gigablox Slot Review
Yggdrasil Gaming demonstrated their approach to sequels with Golden Fish Tank 2 Gigablox, released on 28 October 2021. Rather than overhauling their 2016 original, they integrated the Gigablox mechanic whilst preserving the underwater theme that established the first game as a fan favourite. This represents a measured enhancement strategy: maintain proven aesthetics whilst incorporating contemporary mechanical innovations. The result positions Golden Fish Tank 2 Gigablox as a sequel that respects its heritage rather than chasing complete reinvention.
The game targets players seeking feature-rich gameplay within a relaxing atmosphere. With medium-high volatility and a maximum win potential of 10,000x stake, it sits between casual and high-variance offerings. The Gigablox mechanic adds substantial depth to what was previously a straightforward 25-payline slot, creating engagement across both base game and bonus rounds.
Base Game & Features
Golden Fish Tank 2 Gigablox operates on a 6-reel, 4-row grid with 25 fixed paylines in base configuration. The reel structure expands to 6×6 with 40 paylines when the Expanded Reels modifier triggers during free spins. Bet range spans £0.25 to £100, extending to £120 when Golden Bet is active. This provides flexibility for casual players through to higher-stake enthusiasts.
Symbol hierarchy follows standard structure with card suits (hearts, spades, clubs, diamonds) as low-paying symbols and colourful fish as premiums. Wild symbols substitute for all symbols except scatters, functioning across both regular and Gigablox formations. The RTP sits at 96.00% with medium-high volatility, delivering a hit frequency of 26% (approximately one winning spin in four).
Gigablox Mechanic
The defining mechanic sees at least two adjacent reels connect on every spin to form Gigablox, oversized symbols appearing as 2×2, 3×3, or 4×4 formations in base gameplay. These colossal symbols count as multiple instances of the same symbol, significantly increasing win potential when premium fish or wilds land as Gigablox. During free spins with Expanded Reels active, Gigablox can reach 6×6 size, covering the entire grid. This mechanic injects considerable variance into standard spin outcomes, transforming base game pacing from the original’s modest potential.
Treasure Chest Feature
Treasure Chests land on the fifth reel and guarantee a prize when at least partially visible. In base gameplay, chests award either 2-500x stake instant cash prizes or 5, 9, or 16 free spins. The visual presentation sees bubbles pop to reveal the award, adding tactile feedback to the mechanic. Treasure Chests appearing as Gigablox count as single symbols but tend to award higher average prizes due to their enhanced reel presence. This feature provides consistent engagement across both base and bonus modes, with awards adjusted appropriately for each context.
Golden Bet
Golden Bet is an optional stake enhancement increasing bet cost by 20% (raising the maximum from £100 to £120). The benefit manifests during free spins, granting one additional feature pick beyond the standard 3-7 picks. This allows access to up to six modifiers simultaneously rather than the five available without Golden Bet. For players prioritising maximum modifier combinations in bonus rounds, the 20% premium offers measurable value, though base game functionality remains unchanged. Strategic players can toggle Golden Bet based on bankroll and feature preference.
Golden Fish Tank 2 Gigablox Free Spins
Landing 5 or more scatter symbols triggers the free spins feature, with the number of scatters in view determining initial spin count. Scatter symbols can land as Gigablox, with 2×2 formations containing 4 scatters and 4×4 formations containing 9 scatters, making bonus trigger substantially easier when oversized scatters appear. Players enter a Pick and Click game awarding 3-7 feature picks randomly, with Golden Bet guaranteeing one extra pick.
Six modifiers are available for selection during the pick phase:
- x2 Multiplier: Doubles all wins throughout the bonus round
- Expanded Reels: Adds two rows to create 6×6 grid with 40 paylines and potential 6×6 Gigablox
- Extra Wild: Adds 1-2 wild symbols to random positions per free spin
- Fish Stacks: Allows one premium fish symbol type to land stacked on reels
- Extra Free Spins: Awards 1-5 additional spins to extend the round
- Additional Modifier: Sixth modifier available but mechanics vary by pick outcome
Modifier combinations determine win potential, with Expanded Reels plus x2 Multiplier representing the optimal pairing for maximum 10,000x outcomes. During free spins, Treasure Chests award either 2-500x stake cash prizes or 1, 2, 3, or 5 extra spins, allowing round extension beyond initial allocation.
Gamble Option
After receiving initial feature picks, players can gamble to increase their total up to eight picks maximum. Three starfish appear on screen. Selecting a golden starfish awards an extra pick, whilst a black starfish returns players to base game, forfeiting the entire bonus round. This high-risk mechanic offers 2:1 favourable odds but carries complete loss potential. Players seeking maximum modifiers can gamble conservatively, whilst risk-averse players can proceed with guaranteed picks. The gamble resets after each successful pick, allowing multiple consecutive attempts.
Bonus Buy
Bonus Buy is available for non-UK players only due to UKGC regulations. Two purchase options exist: standard free spins with 5-16 spins and 3-5 feature picks for 60x stake, or Golden Bet version with 5-16 spins and 4-6 feature picks for 83.3x stake. The Golden Bet purchase includes the extra pick benefit without requiring continuous 20% stake increase during base gameplay. UK players access free spins exclusively through natural scatter triggers, maintaining regulatory compliance whilst preserving core feature accessibility.
Our Honest Verdict
Golden Fish Tank 2 Gigablox achieves its objective: enhancing a proven formula without alienating the original’s fanbase. The Gigablox mechanic transforms base game potential from modest to engaging, addressing the first game’s primary limitation whilst maintaining the relaxing underwater aesthetic. Maximum win potential of 10,000x stake (double the original’s ceiling) positions this firmly in medium-high variance territory, though won’t satisfy those chasing truly extreme multipliers available in contemporary high-volatility releases.
The feature richness is substantial. Gigablox in base game, Treasure Chest guaranteed awards, six modifiers across free spins, and optional Golden Bet create multiple engagement layers. Community feedback highlights this variety positively, with players praising the excitement of modifier combinations and frequent bonus triggers. Graphics receive mixed assessment: some reviews note the fish symbols have “Pixar-like loveable goofiness” that lifts mood, whilst others suggest the visual style feels dated compared to more recent releases. The simplified blue sea background and peaceful music contribute to the relaxing atmosphere, appealing to players experiencing theme fatigue from high-intensity mythological slots.
This game suits specific player segments. Fans of the original will appreciate the familiar comfort with gameplay improvements. Feature-focused players seeking bonus round complexity and choice will engage with the modifier system. Mobile players receive excellent optimisation with graphics and navigation matching desktop quality. However, those expecting dramatic departure or cutting-edge visual innovation will find Golden Fish Tank 2 conservative in its approach. Some experienced players note the feature picks can feel tedious when Extra Free Spins dominates picks without complementary modifiers, reducing excitement despite extended play.
Golden Fish Tank 2 Gigablox delivers on its promise: a measured sequel that modernises mechanics whilst preserving charm. It represents solid evolution rather than revolution. For players valuing feature variety and relaxing themes over visual spectacle and extreme variance, this merits consideration. It won’t redefine expectations, but successfully occupies its niche.
