This listing covers Golden Fishtank, a serene underwater-themed video slot carrying the Yggdrasil name, played on a 5-reel, 3-row grid with 20 fixed paylines. It's built around a relaxing aquarium setting and a pick-and-click free spins round that lets players choose their own bonus path.
Expect a colourful, peaceful underwater world of tropical fish, coral reefs, bubbles and shimmering treasure, rendered with fluid animation and gentle water effects throughout. Symbols cover a mix of sea creatures, shells and aquatic elements, and the overall tone is vibrant and calming rather than tense — a good fit for players who want their slot session to feel unhurried. The classic 5x3 layout also keeps the interface familiar for anyone coming from more traditional payline slots.
Golden Fishtank is set at a 95.9% return to player, a solid, slightly-above-average figure for the online slot market. Over a large sample of spins, the game is mathematically designed to pay back £95.90 for every £100 wagered, giving players a fair long-run benchmark to weigh against other titles in the genre.
The game runs at medium volatility, aiming for a reasonably even balance between how often wins land and how large they tend to be. No specific hit-frequency figure is published for this listing, so the free demo is the most reliable way to get a feel for its actual pace before wagering real money, and it's worth running a good number of spins before drawing firm conclusions.
The maximum win is set at 5,000x your stake, a strong ceiling for a medium-volatility game, with bets ranging from 20p up to £100 a spin — flexible enough for both cautious and more confident players.
Landing three or more free spin symbols triggers the bonus round, where players choose from 18 different underwater objects (19 if the Golden Bet option is active), each one revealing a unique feature that stays active for the entire round. That structure gives every free spins trigger a slightly different flavour, since the combination of features selected genuinely changes how the bonus plays out, whether that's added wilds, multipliers, or extra spins.
Golden Fishtank delivers a dependable 95.9% RTP alongside medium volatility and a genuinely strong 5,000x ceiling, wrapped in one of the more calming underwater themes in the slot space. The pick-and-click free spins round is the real draw, giving players a sense of control over how their bonus unfolds.
