Golden Fish Tank 2 Gigablox is the sequel to Yggdrasil Gaming's original underwater slot, rebuilt around the studio's Gigablox mechanic. It runs on a 6-reel grid where reels merge each spin to create oversized 2x2, 3x3 or 4x4 symbol blocks, offering between 25 and 40 paylines depending on how the grid falls.
The aquatic setting returns with plenty of sand, swaying weeds and rising bubbles, and the fish themselves carry a loveable, slightly cartoonish charm across the transparent game grid. Gentle underwater music and satisfying popping sound effects on wins keep the tone relaxed, even as the Gigablox mechanic ramps up the visual scale of winning combinations. When a Gigablox symbol forms part of a win, it breaks down into standard 1x1 symbols for payout purposes, so the bigger blocks translate directly into bigger wins.
Golden Fish Tank 2 Gigablox is set at a 96% return to player, a solid, above-average figure. Over a large number of spins, the game is mathematically designed to pay back £96 for every £100 wagered — a dependable benchmark, even though any individual session can swing well above or below that long-run average.
The volatility here sits between medium and high, and the published hit frequency of 26% means roughly one in four spins produces a win. That's a reasonably active pace for a game with this level of swing, helped along by the Gigablox mechanic's tendency to occasionally produce outsized single-spin results.
The maximum win is capped at 5,000x your stake, with bets running from 25p up to £100 a spin. The game's Golden Bet option increases your stake by 20% in exchange for an extra feature pick when free spins trigger, giving players a way to nudge the odds in their favour for a modest cost.
Low-value symbols cover familiar playing-card style icons, while the fish-themed premiums carry the bulk of the paytable. Wins are formed by landing matching symbols on consecutive reels from left to right, and the free spins round is reached through a scatter trigger, with feature picks determining exactly what bonus mechanics come into play during the round.
Golden Fish Tank 2 Gigablox takes a proven underwater theme and gives it real scale through the Gigablox block mechanic, delivering a solid 96% RTP with medium-to-high volatility and a healthy 5,000x ceiling. It's a strong option for players who enjoyed the original and want bigger single-spin potential. Dive into the free demo on johnessyslots to see the Gigablox blocks in action before playing for real.
