Golden Fish Tank Slot Review
Sunlight slants down through a rippling water surface and fades into pale turquoise, over reels that sit on a sandy seafloor fringed with pink, purple and orange coral. This tank has personality. Golden Fish Tank asks you to pick the modifiers its free spins round runs on, from hidden objects at the bottom of that seabed, and that choice does more for the game than any amount of gloss on the coral.
Yggdrasil’s underwater outing runs on a 5×3 grid with 20 paylines, a 96.4% RTP and medium volatility, with a top prize of 2,000x the bet. Stakes run from 0.2 to 100 per spin. It’s the game Golden Fish Tank 2 Gigablox built on, and it sits alongside studio favourites like Cazino Cosmos and Vikings Go To Olympus in the Yggdrasil catalogue.
Base Game & Features
All 20 paylines pay from the left, and eight regular symbols win when three or more line up in sequence starting from the leftmost reel. The number of lines is fixed. Only the highest winning combination per line is paid, and if a winning line starts with wilds, only the best interpretation of that line counts.
To work out a payline win, count identical symbols in sequence from the far left and find the matching row in the paytable. The bet is one coin per payline, so your stake is always coins times lines, and wins in coins convert to your currency through the coin value. Nothing here departs from the standard left-to-right formula.
The medium volatility and a hit rate of 33.5% mean the reels connect often enough to keep sessions moving. Wilds substitute for all symbols except the Free Spins symbol, and they always stand in for the highest winning combination from left to right. Beyond that, the base game keeps things simple: the real work happens once the bonus triggers.
The Golden Bet
Golden Bet is an optional ante that costs 25% extra per spin. In exchange, triggering free spins grants one additional feature pick in the bonus game. It’s a modest price for a genuinely useful upgrade, and it’s the one base game decision that matters here.
Autoplay is on hand if you’d rather set a round count and conditions, including a loss limit, and let it run. Wins during the base game are added up line by line. When the free spins round finishes, its total is added to any win from the spin that triggered it, so nothing is lost between modes.
Symbol Values
The four low-paying card symbols carry the smaller end of the paytable, with values below shown at the default stake of 1.40:
- Heart: 3 pays 0.25, 4 pays 1.25, 5 pays 3.75
- Spade: 3 pays 0.25, 4 pays 1.00, 5 pays 3.00
- Club: 3 pays 0.20, 4 pays 1.00, 5 pays 2.50
- Diamond: 3 pays 0.20, 4 pays 0.75, 5 pays 2.50
Four fish symbols sit above the royals, again at the default 1.40 stake:
- Highest fish: 3 pays 1.25, 4 pays 3.50, 5 pays 12.50
- Second fish: 3 pays 1.00, 4 pays 3.00, 5 pays 10.00
- Third fish: 3 pays 0.75, 4 pays 2.75, 5 pays 8.75
- Fourth fish: 3 pays 0.50, 4 pays 2.50, 5 pays 7.50
The gaps tell the story. Five of a kind is worth ten times the three-of-a-kind pay on the top fish, while the royals barely double from three to five. The fish are where the real money is, and the feature picks that turn them wild or stack them are built around exactly that.
Golden Fish Tank Free Spins & Feature Picks
Three or more Free Spins symbols anywhere on the screen activate the free spins mode, which plays with the same bet and lines that triggered it:
- 3 Free Spins symbols: 6 free spins with 3 feature picks
- 4 Free Spins symbols: 8 free spins with 4 feature picks
- 5 Free Spins symbols: 10 free spins with 5 feature picks
Before the round begins, 18 objects rise from the bottom of the tank and you pick from them. Each hides a feature that stays active for the entire free spins session, so the picks you make shape the whole round. With Golden Bet active, one extra pick is added on top.
What the Picks Contain
The 18 objects hide the following features:
- Extra free spins: 2 or 4 additional spins
- x2 multiplier on all wins
- 1-2 random wilds added to random positions each free spin
- A sticky wild locked to the middle position of reel two, three or four for the whole session
- One of the four fish symbols acting as a wild
- High stacks of one fish symbol across the reels
Only one fish type can be stacked in a round, and picking a stacked fish disables the other three stacked-fish objects. There are no Free Spins symbols during free spins, so the round can’t retrigger and the initial spin count is final unless extra spins are picked.
The wilds deserve a closer look, because there are three distinct types. The regular wild appears in the base game and as random wilds in free spins. The sticky wild exists only in free spins, holding its position once placed.
The fish wilds are the picked symbols that gain wild behaviour, and each of the four fish ranks has its own object in the pool, so a pick can turn the highest, second, third or fourth fish wild. A sticky wild on a middle reel pairs well with the multiplier, since the wild sits in the highest-traffic position for every remaining spin. Random wilds suit shorter rounds, where a wild landing somewhere new each spin adds up quickly.
Stacked fish reward patience, because a high stack of a top-paying symbol can cover a whole reel at once. That’s the pick with the biggest single-spin upside.
Our Honest Verdict
Overall Rating: 7.7/10
This is a game you drift through, and the drifting is the point. The base game spins along on a steady hit rate while you wait for the tank to open, and the one reason to choose it over a dozen prettier fish slots is that when the bonus arrives, you’re the one stocking it. That pick-and-click moment is the best thing here, and it still works a decade on: choosing between a sticky wild and a 2x multiplier is a real decision, and the good rounds feel earned because you built them.
A 2,000x maximum win caps what all that clever picking can add up to, and with no retrigger, a great round ends when the last spin ends. It also looks its age next to the sequel.
For players who enjoy shaping a bonus rather than just receiving it, this is still one of the more satisfying ways to do it in calm water. The big-multiplier hunters were never going to stop at this tank anyway.
