Top Underwater Slots Banner

One of the most popular themes in online slot games is underwater, ocean-themed or fishing slots. These games explore the vast treasures that lie beneath the surface of the ocean and often feature mermaids, dolphins, pirates, ships, and more. Often, you will be on the trail of sunken treasures when playing an underwater-themed games game.

The best part about these titles is that they usually have unique symbols, features, and bonuses that are specially designed for each game. Rarely will you find the same features in two different games of this genre. Moreover, the ocean is often associated with hidden treasures, buried centuries ago. This is perhaps why this theme continues to be so popular with slot a-fish-ionados.

Eye of the Kraken

Experience the power of a legendary sea creature. The Kraken guards a valuable treasure hidden deep in the ocean, and you must confront the beast to claim it. Eye of the Kraken is played on a 3x3 grid with dynamic eight paylines. You also have the chance to win up to x500 times your original bet. Originally released back in 2015, this title remains a fan favourite to this day.

The animations in this game make you feel as if you’re aboard the submarine in search of the kraken. Each symbol, including a compass and diving gear, seamlessly matches the underwater kraken theme. The bonus symbols drop frequently. The Wild Kraken’s tentacles appear on the grid and drop Wild symbols. Collecting 50 torpedoes will trigger the Conquer the Kraken bonus which lets you open treasure chests. Five or more helmets activate the Dive Mode where you get Free Spins and additional Wilds. Better get diving!

Boat Bonanza

Reel in a big catch as Boat Bonanza offers you an opportunity to embark on an exciting treasure hunt across the sea. This slot game has a 5x3 grid and 12 paylines. You can win a maximum possible of 5,000x your bet – upping potential tenfold.

The high-quality graphics and animation bring the oceanic theme to life on your screen. 

Symbols like seagulls, lobster cages, and lifebuoys can be found on the reels along with many unique features that make for a fun gameplay experience.

This feature-rich game offers four main features. First, there are Free Spins which are triggered by landing three Scatters. Then, there is the Mega Catch. In this, a huge net is cast across your grid to reel in prizes from all reels. There are also Instant Prizes up for grabs throughout the game. Finally, there is the coveted Golden Lobster. Land this and you can get 1000x of your total bet. 

Let’s go fishing!

Octopus Treasure

Accompany the octopus in a legendary treasure hunt at the bottom of the ocean. The game was released in September 2020 and comes with five reels, three rows, and 20 fixed paylines.

Spades, diamonds, hearts, and clubs, looking like precious artefacts, are the low-paying symbols here. Together with the higher-paying symbols like an oyster and silver trinkets, the overall graphics and animation complemented by the soundtrack adds further to the immersion of the gameplay as you dive to the depths of the deep blue sea.

A big gold key symbol landing on reel 3 will unlock a slew of features and Multipliers. A treasure chest will open to reveal one of four bonus features. Each of these triggers a different Multiplier. The Pearl Scatter will trigger the Key Re-Spins if it lands on reels 1, 3, and 5 simultaneously. In the Treasure Spins feature, you can get between five and 10 Free Spins. 

Are you ready to take on the tentacles?

Sea Hunter

Be prepared to dive deep into the sea in this 3x5 reel game. Released in 2017, Sea Hunter remains a modern Play’n GO classic to this day. This game comes with four special cannons that appear on the sides of the grid and fire at the reels to get you more wins.

The slot is heavily inspired by sea creatures of all sorts which might remind you a little of Finding Nemo. Various fish symbols on the reels appear against a slightly blurry backdrop where you can see the treasures on the bed of the sea, waiting to be found. 

The Cannon Meter is the main feature of this game where you get to see four different types of cannons. You can power up the cannon by landing two or more winning combinations consecutively, which triggers some explosive features.

However, every non-winning spin will reset the meter and you begin from scratch. All the cannons give you different rewards depending on which one appears on your screen – Growth Gun, Sticky Shot, Wild Warhead, or Multiply Mortar. The key to landing rewards in this game is to get consecutive winning spins.

Let the hunt begin...
