Symbols and Payouts
The paytable is short and clear. Four card suits fill the low end, four cartoon fish make up the premium tier, and two special symbols drive the action. Wins pay for 3, 4 or 5 matching symbols on a line from the leftmost reel.
The top-paying regular symbol is the yellow-and-green striped fish. Landing five on a line pays 12.5x your total stake.
| Hearts, Clubs, Spades, Diamonds | Low-paying symbols |
| Blue fish, pink fish, orange fish | Mid to high-paying symbols |
| Yellow-and-green striped fish | Top regular symbol, 12.5x stake for five |
| Wild | Replaces every regular symbol except Free Spins |
| Free Spins fish | Scatter that starts the bonus round |
Golden Bet
Golden Bet is an optional side setting on the bet panel. It adds 25% to each spin, so a $1.00 spin becomes $1.25. Your reward is an extra feature pick every time free spins begin.
That extra pick is more important than it seems. With five scatters and Golden Bet active, you make six picks from six possible features, playing the round with all modifiers on.
- Cost: a 25% increase to every spin
- Reward: an additional feature pick per bonus round
- RTP effect: the full 96.8% applies only with Golden Bet active
- Best use: for longer sessions where you aim for the bonus round
Free Spins and Feature Picks
Three or more Free Spins fish trigger the bonus. Before spinning, 18 objects float up from the tank bottom. Each hides a unique modifier that lasts the entire round.
| Free Spins symbols | Free spins | Feature picks |
|---|---|---|
| 3 | 6 | 3 |
| 4 | 8 | 4 |
| 5 | 10 | 5 |
The Six Modifiers
Each modifier changes the round differently, and you cannot select the same feature twice.
- Extra Free Spins: adds either 2 or 4 spins to the round
- Multiplier Wins: every free spins win pays 2x
- High Fish Stacks: one fish appears in tall stacks on the reels
- Fish Wild: a selected fish becomes a second wild symbol
- Random Wilds: 1 or 2 wilds land randomly on each spin
- Sticky Wild: one wild stays fixed until the round finishes
Best Feature Combinations
Modifiers combine, and some pairs work exceptionally well together. Fish Wild alongside High Fish Stacks fills entire reels with wilds. Sticky Wild plus Random Wilds creates a grid where most lines connect.
- Multiplier Wins and High Fish Stacks: tall fish symbols land on multiple lines and trigger double payouts
- Sticky Wild and Random Wilds: a permanent wild remains, and new wilds appear on each spin
- Fish Wild and High Fish Stacks: stacked fish symbols can transform into wilds covering full reels
- Extra Free Spins and Multiplier Wins: win additional spins with doubled payout values
The picks are random, so you cannot control the result. You only choose how many picks you receive, based on your scatter symbols and Golden Bet selection.
RTP, Volatility and Max Win
Golden Fish Tank has an RTP of up to 96.8%, which is higher than the 96% slot average. Medium-high volatility delivers small, frequent wins in the base game. The largest payouts almost always come from the free spins feature.
The $100,000 maximum prize requires the highest bet. With smaller stakes, the biggest wins happen when the bonus round combines multipliers and stacked fish.
- Base game: regular small wins from card suit symbols and lower-value fish
- Bonus round: this is where the major prizes are found
- Bankroll: expect quiet periods between bonus triggers
- Session tip: decide your loss limit beforehand and do not exceed it
Theme and Graphics
The game shows a bright aquarium floor with coral, plants and rising bubbles. Cartoon fish with big eyes move between spins. The reels appear in clear water without a border.
During free spins, the tank darkens to a deep purple and wilds appear inside glowing bubbles. A mellow jazz soundtrack and gentle water sounds play.
- Art style: colourful cartoon fish and shiny gem-like card suits
- Free spins scene: darker water, luminous wilds, and floating bubble effects
- Sound: laid-back jazz mixed with underwater audio
- Format: 16:9 widescreen ratio, full-screen on mobile devices

The Golden Fish Tank Series
The first game expanded into a three-title series. Each follow-up retains the aquarium setting and fish characters but introduces a fresh main mechanic.
| Game | Release | Layout | RTP | Max win | Key mechanic |
|---|---|---|---|---|---|
| Golden Fish Tank | 2016 | 5x3, 20 lines | 96.8% | $100,000 | Feature picks in free spins |
| Golden Fish Tank 2 Gigablox | 2021 | 6 reels, 25-40 lines | 96% | 5,000x | Gigablox giant symbols |
| Golden Fish Tank Party | 2024 | 6x4, 4,096 ways | 94% | 6,000x | Cash and Collect with two bonus modes |
The original still offers the highest RTP among the three. The sequels sacrifice some of that return for bigger maximum wins and more volatile gameplay.
