10 Best Ocean Themed Slots in 2022
Win with the help of a beautiful mermaid.
Meet a beautiful mermaid born in the Microgaming factory and spin the reels to form winning combinations over 25 pay lines. The catch of the day, amounting to 30,000 credits, could be taken home thanks to expanding symbols. During the base game, any full symbol stack on reel 1 expands all matching symbols on the other reels and while in the free games mode, the same will also happen to wild icons.
#9. Maritime Maidens
Pick free spins or cash in the bonus round.
This lovely video slot by Genesis Gaming comes with 5 reels, 25 pay lines, and no less than 5 enchanting mermaids.
Wilds can pay as much as 1,000x your line bet and Scatters activate a bonus round that offers you a choice. You can either select Maritime Free Spins with random wilds added to the reels on each spin or Oyster Picks, which is a pick-and-click affair awarding cash prizes.

The Super Free Spins feature rewards you with up to 25 free spins played on a new set of reels. Wild multipliers are once again present and extra stacks of the highest value mermaid symbol are thrown in.
Queen of Atlantis can be found at Videoslots.
#7. Under the Sea
Discover the treasures hiding under the sea.
Under the Sea features amazing 3D visuals and attention to detail that’s characteristic of BetSoft games.
The reel area sits at the bottom of the ocean, among starfish, corals, and sea plants, providing 30 lines to match the symbols and collect the prize.

This ocean-themed slot from Microgaming features 5 reels and 50 pay lines, giving you the chance to collect as much as 300,000 credits.
You’ll have two wild icons to benefit from—a standard one that does only the substitution (though it can also appear stacked), and a wild Scatter that triggers the Dolphin Quest Bonus. You’ll get a new set of reels containing prize amounts and all you have to do is press the Stop button to collect the one displayed on the win line.
You can play this game at Playluck
#5. Reef Run
Tons of free games and multipliers.
This visually appealing Yggdrasil 5-reel and 20-payline slot can score you a max of 20,000 coins per line.
Although there aren’t tons of features to take advantage of, they do offer enough to claim respectable wins. The Free Spins symbols will let you play as many as 60 free games, while the additional Level-up Feature awards increase multipliers and additional free spins each time you win with the same character.
You can enjoy Reef Run at the William Hill.
#4. Dolphin Cash
Xtra win mode adds expanding wilds.
Playtech takes us to an exotic tropical location and provides a set of semi-transparent reels with 30 pay lines.
The golden coin launches free games and the full moon awards the Dolphin Cash Bonus. You’ll have to help the dolphin collect coins for instant cash rewards by pressing the Jump arrow. Each coin win equals your total stake. Investing an additional 50% of your bet will activate the Xtra Win mode, during which the wild icon on reel 5 expands up or down, depending on its original position. Both then become shifting wilds, meaning they’ll move one step to the left with each spin.
#3. Eye of the Kraken
Scary monster, scary big wins.
Play’n Go has produced a unique and feature-packed slot that will provide an engaging underwater experience (if you don’t let the sea monster scare you, that is).
The 3-reel slot comes with 8 pay lines that run horizontally, vertically, and diagonally, and an occasional appearance of the Kraken, who will wrap his tentacles around the reels to change symbols into wilds. Collect 50 torpedoes and you’ll activate the Conquer the Kraken bonus feature, which lets you pick 3 treasure chests to win cash prizes of up to 500x your stake. Moreover, helmets will launch Dive Mode, in which you’ll get to collect special prizes while spinning for free.
This visually stunning and exciting game can be played at Mr. Green.
#2. Silent Run
Torpedo enemy ships to win.
The 5-reel and 25-payline NetEnt slot will engage you in an underwater battle and expose you to a couple of truly unique features. The echo bonus symbol sends out 3 sonar signals to locate the torpedoes, which you’ll later use in the bonus game.
Choose an enemy ship, aim, and fire to reveal the reward boosted by a multiplier attached to each torpedo. While a standard wild does its regular job, Echo wilds send signals to search the reel area for other hidden wilds.
The game is available at William Hill
Unique slot packed with features
Featuring clips and scenes from the original movie, this Bally video slot has so much going on that it’s impossible to describe in a few sentences.
It’s different from the moment you launch it, offering 3 choices as far as your stakes go. A line bet of 0.01 will buy you a 3rd class ticket that comes with Wheel and Mystery features. Invest between 0.02 and 0.04 and you’ll receive a 2nd class ticket which adds Mystery Jackpots. The 1st class ticket costs 0.05 and throws in Top Award Jackpots.
The wheel feature prompts you to spin the wheel to either win cash prizes or launch Make It Count free games, Heart of the Ocean free games, the Pick-and-Click Safe bonus round, or the Pick-Up feature, which delivers cash prizes and multipliers. Randomly awarded Mystery features include the Double Wilds feature, Wild Reel feature, and the Jacks drawing feature, which can pay as much as 2,000x your line stake.
