Fishin’ Frenzy

I’m kicking off my list of the best fish slots online with the game that started it all – Fishin’ Frenzy. This classic has been hooking players for years with its simple but effective gameplay. Match those wily fish symbols across the 5 reels and 10 paylines to earn prizes galore. The fish collect feature was making waves long before Playtech brought their Cash Collect bonus to the market, and it is still the first and best way to collect cash prizes. 

Fishin’ Frenzy Even Bigger Catch

There are over 16 Fishin Frenzy slots in the at the time I wrote this, making it arguably the biggest and most popular fish slots collection. As well as the usual fish collect bonus with multipliers, this one has free games with a fish upgrade feature, and a 10,000 max haul. The graphics aren’t much to speak of, but that’s not why thousands of OJOers play this game every month.

Big Bass Bonanza

The original Reel Kingdom aquatic adventure may have been surpassed by over 10 more recent games in the series, but it’s no small fry. It’s slightly less volatile than the others games, but with money symbols galore, free spins and retriggers with multipliers, Big Bass Bonanza is a classic. Maybe that’s why it is also the slot you’ll get free spins for when you make your first deposit at PlayOJO! No wagering, terms apply. 

Big Bass Splash

Big Bass Splash is probably the most successful Big Bass slot, probably because of the reel modifiers that are added during free spins. There’s up to 20 free spins up for grabs in the bonus round, and if you’re lucky, you’ll hook more fish, more fisherman wilds, or more spins. The cash collect feature has money symbols that range from 2x to a whopping 5,000x in free spins. If you play one fish slots game after reading this article, make it this one.  

Big Bass Amazon Xtreme

The Amazon river is legendary for its monsters and in this game, it’s the money symbols that are lurking in the deep. In the base game, they go up to 50x and in the free spins bonus, they get as big as 1,000x. The free spins bonus has a nice respin twist, the graphics are as impressive as you’d expect from a Big Bass slot, and with a max win of 10,000x, this one’s a worthy addition to the series.

Fishin’ Pots of Gold Gold Blitz

They say there’s a pot of gold at the end of the rainbow, but in this slot, you’ll be angling for golden riches under the sea. Collect symbols on reels 1 and 6 are the primary way to catch prizes in this game, though the main draw is the scatter, which gives you the choice of up to 30 regular free spins or 7 Gold Blitz free spins. Both have 2x, 3x or 5x multiplier wilds, and the Gold Blitz produces wins on every spin.

Fishin’ BIGGER Pots of Gold

This is the slot that asked “How can we make Fishin’ Pots of Gold even better?” And the answer was to go BIGGER – with BIGGER paylines, and BIGGER win potential. You get 10 more paylines in the free spins feature, and the Accumulation Trail is my favourite of the lot.

Nice Catch 2

Like all Yggdrasil slots, this one is packed with great features, including the cash symbols that are compulsory in fish themed slots. There DoubleMax multipliers of up to 32x in the base game when you land fish symbols on consecutive reels, a Hold & Win respin game and scatters can trigger up to 20 free spins. It’s nice to see a 729 Ways game being released into the slots sea too.

4 Fantastic Fish

As the name implies, this slot is all about four fantastic fish that can make your wildest wins come true. There’s a 15,000x top prize and some outstanding features, my favourite being the Giant Squid bonus. This game is all about collecting cash fish of differing values. I love the sticky fish during respins, plus the Big Reel mode in phone portrait mode is a very nice touch.

Mighty Fish Blue Marlin

Last but not least, we have the mighty Mighty Fish Blue Marlin, an unusual fishing slots game with no paylines and no base game symbols. It’s basically a Cash Collect style slot with jackpots and a 2,500x max win. You can pick your own volatility level too, which I particularly like in a slot.

Bait up, take the plunge, and reel in some fishy fun.

What are fish games? 

Fish games are a new type of online gambling game from Asia that is not to be confused with fish casino slots. Although they use slot mechanics, fish games are a type of shooting game where players target fish moving across the screen. Fish come in various shapes and sizes, with bigger fish more likely to trigger bonus features, rather than instant cash prizes.  
Instead of placing bets, players wager real money by using weapons to catch fish, with bigger more valuable fish requiring higher value weaponry. Although fish games are incredibly popular in the Far East, they have not yet arrived at UK online casinos, but given their popularity, it’s only a matter of time!
