Big Bass Bonanza by Pragmatic Play

Ask most players which is the best fishing casino game, and Big Bass Bonanza by Pragmatic Play is going to be right up there. This 5×3 slot carries an above-average RTP of 96.71% and has a high volatility rating. There are 10 payline configurations. It means you might have to wait a little longer for payouts, but when they come, they are worth waiting for.
The 10 to A card symbols are the low payers, each being worth $ 0.60 for 3 of the same, $3 for 4, and $12 for 5 of the same. The highest paying symbol is the Float – you win $0.60 for 2, $6 for 3, $24 for 4, and $240 for 5. The Wild is the Fisherman, and the Scatter is the Leaping, Hooked Fish. 3 Scatter trigger 10 Free Spins, 4 triggers 15, and 5 triggers 20 Free Spins.
The Shoal of Fish in the money symbol the value of which is random, anywhere from 2x to 2,000x your stake. The smallest bet is $0.10 per spin, and the maximum, $250. The maximum win is limited up to 2,100x your wager.
Golden Fish Tank 2 Gigablox by Yggdrasil

The second of the best fishing themed slot games in this GamBonus review is Golden Fish Tank 2 Gigablox by Yggdrasil. The graphics in this 5×4 slot are simple but beautifully designed. The fishes are cartoon-type caricatures with smiley faces and gazes of big-eyed wonderment. The symbols, including what look like aquatic 3-Leaf Clover Leaves, Ruby Red Hearts, Blue Diamonds, and Inverted Purple Spades, bob gently up and down against a serene ocean-blue background.
The Wild is the word ‘Wild,’ and as well as substituting for all regular symbols, it also has its own paytable. There is also a Fish Free Spins Scatter. With each spin, a minimum of 2 adjacent reels combine to form a 4×4 Gigablox, which can expand to a 6×6 Gigablox with extended reels. There’s also a Golden Bet feature, which awards a feature pick when the Free Spins are triggered. There is also a treasure chest feature, which appears on the 5th reel, awarding 2-500x wager cash wins and 1 to 16 extra Free Spins.
For many players, this is the best fishing casino game thanks to its many features. It has an RTP of 96% and a medium to high volatility rating.
Razor Shark by Push Gaming

The 20-payline 5×4 Razor Shark slot is the antithesis of the colourful plaything-type fishing slots. This slot has a sense of menace about it courtesy of the subdued green setting of the reels and the array of debris, including an aqualung, a pair of flippers and a diving mask lying abandoned on the ocean floor. The animation of the evil grinning shark as it opens and closes its jaws reminds you that you are in grave danger as you seek out winning paylines.
Razor Shark is a feature-rich slot including:
- The Razor Reveal awards multipliers to significantly increase your winnings.
- Seaweed symbols that change into matching symbols.
- Free spins each with progressive multipliers.
- Nudgeable Mystery Stacks during the free spins rounds.
The soundtrack keeps the pulse racing. It’s a race against time as you attempt to land the x85,475 multiplier on this high-volatility slot. With its 96,7% RTP, since its launch in 2019, Razor Shark is reckoned by many to be one of the best fishing themed slot games of all time.
Big Bass Mission Fishin’ by Pragmatic Play

Pragmatic Play’s Big Bass fishing slots series welcomes another member to its family in the form of Big Bass Mission Fishin. In this game, you’re taken deep down beneath the ocean surface where you’ll find various treasures, prizes and bonus features culminating in a top win of 5,000x your wager.
This latest instalment of the Big Bass story is of a noticeably darker mood, with its symbols that consist of dragonflies, harpoons, and tackleboxes. You’ll still find the 10, J, Q, K, and A symbols, albeit with higher values than on the original. The speedboat is the highest-paying symbol, with 5 of them being worth £400. Like the Big Bass fishing slot games’ predecessors, the bearded fisherman still fulfils the role of the Wild, as does the Leaping Sea Bass in its job as the Scatter.
The paylines are activated by landing 3 like symbols on consecutive reels from left to right; the only exception is the speed boat, which pays even if you land only 2.
Big Bass Mission Fishin introduces a new feature – the Stack the Cash game. It’s a Hold and Win bonus game in which Cash Coins carry a value of up to 25x your stake. This new Big Bass game has an above-average RTP of 96.5% and carries a high volatility rating.
4 Fantastic Fish by Yggdrasil

The 4 Fantastic Fish slot from 4ThePlayer is a 6-reel slot that provides you with 4,096 ways to win. To grab a winning combination, you’ll need to land 3 or more, or 2 plus of the higher paying symbols, from left to right, starting from reel 1.
The game’s Cash Ways feature, where the Giant Squid appears to lend a helping tentacle, is a fun round but is also a good example of how the gameplay can be a little confusing to begin with, so our GamBonus team definitely recommend trying a free demo version first, like the one on Zotabet Casino.
The fishing slot’s Fish symbols can appear on any of the 6 reels. Each little fish has its own unique Cash value, which can be anywhere from 0.2x to 100x. In a similar way to Big Bass Bonanza, the larger the fish, the larger the win. You need 3 or more to form a winning combination. When the Cash Ways feature is triggered, the cash value of each of the fish gets added together to form the cash prize.
It can be quite difficult to get those little Fish symbols to form a winning combo. They miss out more than not. Thank goodness that 4ThePlayer has included a Giant Squid in the game, which helps to realign the little money fish, improving the Cash Ways win, or creating a new one.
Now you’ll see why 4 Fantastic Fish is one of the best fishing themed slot games. On reel 6, 4 special Fish symbols might appear, and if you manage to land a winning combo of fish symbols that corresponds to one of the Specials, you’ll trigger one of 4 jackpots.
- The Big Jackpot, which is worth 100x your wager.
- The Super Jackpot, which is worth 500x your wager.
- The Mega Jackpot, which is worth 2,000x your wager.
- The Ultra Jackpot, which is worth 10,000x your wager.
That’s some serious winnings right there. With 4,096 ways to win, 4 Fantastic Fish has a 96% RTP and is a low-volatility slot.
Fish and Cash by Popiplay

The 3D slot from Scandinavian software designer Popiplay. Fish and Cash is a typical Popiplay game with excellent, memorable, cartoon-figured characters and symbols that are part and parcel of their amusing slot worlds.
Fish and Cash is a high volatility 6×5 cluster pays slot. At 98.08%, it has the highest RTP of all of the fishing slot games we’ve reviewed. The game’s features include a buy bonus, and a chance booster, free spins, and a maximum payout of 10,200 your wager. The free spins are triggered by the Treasure Chest Scatter, which also pays out up to 100x your wager if you can land 6.
The game features a determined, grim-looking fisherman bobbing precariously up and down in his boat, which, from time to time, nearly gets overturned by a surfacing whale.
Small wins come thick and fast, which is great for keeping your interest, but typical of high volatility slots, you have to persevere to land bigger wins.
Golden Fish by KA Gaming

Next on our list of the best fishing themed slot games is the Golden Fish slot from KA Gaming. It’s a 5×3 oriental fish-themed slot with an admittedly annoying soundtrack, made worse by the fact that it starts and stops with each spin. In our humble opinion, it would be less annoying if it continued to play. However, you can always turn it off.
This slot is all about the fabled Golden Fish of China, a symbol that represents luck and prosperity, and which, according to Chinese folklore, can only be discovered by the chosen.
The format of this slot game is 5×3 with 25 fixed paylines. In its true quirky fashion, KA Gaming introduces a variety of Chinese symbols, including a Red Money Bag, the Chinese Gourd (wine bottle), the Ancient Chinese Golden Coin, and a Golden Chinese God Hat. The Scatter is the Yuan Bao Wealth Ingot (a symbol of wealth in China). The Wild in the Chinese Golden Carp.
Although the Golden Fish slot is fun to play, and therefore worthy of being included in our list of the best fishing themed slot games, you won’t strike it rich. The maximum bet size is £125, and the biggest multiplier is 15x your stake, so the biggest payout is £1,500. Another disappointment is that this game has a below-average RTP of 94%, which is why it’s placed lower down our fishing slot games list.
Fish and Bird by Elf Studios

As we come to end of our review of the best fishing themed slot games, we introduce a strong contender for the winner. Fish and Bird by Elf Studios is a brand new game released in August 2025. It’s a delightful change from the run-of-the-mill fishing slot gams with its amusing animations and jaunty backing track, enhanced by the bubbling and gurgling sounds as its 4×4 reels spin.
When the old, fat old fisherman rows out, he’s not afraid of swiping his net overhead to see if he can catch a seagull or two, and for each one he catches, you’ll be rewarded.
The slot features spreading Wilds both horizontal and vertical, plus prize fish and multipliers. If the old man catches a mermaid, it can trigger the bonus or super bonus feature.
Look out for the Elk Studios ‘X-iter,’ a feature granting you five different game modes with a variety of bet sizes and bonus trigger rates.
Even though the Fish and Bird RTP is only 94%, we think you’ll have great fun trying to land the top prize of 10,000x your wager. Seriously, people, the team here at GamBonus rates this as one of the best fishing themed slot games around at the moment and is well worth a try.
Jellyfish Flow by Habanero
Hats off to Habanero. Its Jellyfish Flow slot has some of the best graphics our expert team here at GamBonus has come across in a long time. Especially when you land a big win. Not only that, but the soundtrack is also refreshingly good, with its haunting background and beautiful choral choir backing during the special bonus feature. The entertainment doesn’t stop here, though.
Jellyfish Flow might start off looking like one of those basic 3×3 fishing slot games with 27 ways to win, but as you know, looks can be deceiving. The grid can expand up to 7×7, giving you a massive 823,543 ways to win. It’s triggered by the Wild.
With a maximum win of 150,000, Jellyfish Flow is a triumph that blends imaginative creation with some truly innovative features and its flexible gameplay. The RTP is 96.76%.In our opinion, Jellyfish Flows is the best of the fishing themed slot games. If you haven’t tried it yet, you are in for a real treat. However, it’s the sort of slot that can be really addictive to play, so please remember to always gamble responsibly.
