Dive into an underwater realm of cartoon jellyfish, anglerfish, and seashells with the Shark Abyss online slot. Dipping into this desktop and mobile game I found cascades on every win plus a great white shark that can substitute for others, and acts as the trigger for an exciting Pressure Pays mechanism. The shark replaces lower value symbols, adding multipliers and can drop right into the depths for greater payouts at the end. There are also free spins with ever-increasing multipliers throughout and this is where I saw my biggest wins.

Fans of online slots with an underwater theme will love the cartoon critters here. You’ll find a cute Dumbo octopus, wise-looking jellyfish, scary anglerfish and bug-eyed pufferfish here, alongside a range of seashells and starfish. The apex predator of the Shark Abyss slot machine is a grinning great white and a giant squid bonus symbol awards free spins.
I like the theme, bright colors, and plentiful animations as winning symbol positions crack under the pressure, fish come to life, and the shark appears to leap from the reels when he’s part of a win. Developed by Tornado Games, it’s a good example of the type, that comes in desktop and mobile versions, so you can explore the ocean from wherever you may be.
Casual players will appreciate a low 0.1 credit entry point, while higher rollers can jump right in with stakes of up to 160 credits. Symbols land on five reels, and six rows, with 50 lines crossing this grid from the left. It’s a game that tends to pay higher prizes, but with more losing spins than winners, so set your bet at a level where the game can take a few bites out of your bankroll. The return to players of 96.20% is right around where I expect from high volatility games such as this.
I usually read through the payable of games new to me, then play the free version on VegasSlotsOnline. Spinning the reels of the Shark Abyss slot, I soon found out that even though there’s no mention of this on the payable, every win triggers cascades, as the winning symbols vanish and new ones drop into replace them. It was a nice surprise that often saw several winning combinations from a single paid spin.
The shark is your friend here. He’s a 2x2 wild symbol who can act as others and if he lands on lower value symbols, a Pressure Pays feature triggers. The wild crushes the shells, taking their places, then applying a 2x multiplier to all adjacent positions. It can drop down multiple rows as long as low paying shells are underneath, applying more multipliers which boost any wins from the feature. I managed a couple of big wins this way, but in my experience, the wild shark is a rare species, and Pressure Pays didn’t trigger very often.
The fearsome giant squid in any three places grabs 10 free spins from the Shark Abyss online slot. There’s a nice animation as the backdrop changes from shallower waters to the depth of the ocean, where symbols gain a luminous green color. The other big difference between the free spins and base games is that any multipliers from Pressure Pays remain in place, building in value any time the shark crushes shells. You also get an extra five, eight, and 12 free games if three, four, or five bonus symbols land at once.
Here’s a list of symbol values shown as multiples of the total bet -
The artists at Tornado Games have done a great job, with lots of character and personality to the various sea creatures. I like the excitement of highly volatile games, where there’s the chance of a big win at any time, but as mentioned, set your stakes accordingly and don’t bet too much of your bankroll on each spin. Patience can pay off as you get through to features. I was a little let down by the Pressure Pays feature, which is enjoyable, but very uncommon.
If you want to play games with a similar theme to Shark Abyss, then popular alternatives include the Razor Shark slot machine from Push Gaming and the Shark Meet online slot by Booming Games.
A few more Pressure Pays triggers would be good, although maybe I was just a little unlucky as I played the Shark Abyss slot online. It looks great, with lots of enjoyable animations and in terms of the graphics, perhaps among the best online slots with an underwater theme. Cascades on every win, giant wilds, multipliers, and free spins give the gameplay some depth, while wins can hit up to 5,000x the stake over the course of the bonus round.
