Adorable aquatic creatures such as multi-colored jellyfish, octopus, goldfish, squids, pufferfish, angelfish, and turtles occupy the gameboard. These aquatic animals award payouts of up to 32x the bet per line for combinations of three or more. 

As for the bonus symbols, the game logo Scatter activates an exciting Free Games feature where you’ll win up to 20 Free Spins complete with a double Multiplier. The toothy-grinned Shark acts as the Wild, swimming into action to replace low-paying symbols and increase your chances of landing a huge win. 

Bursting Wilds are also a given during the base game and Free Games feature in this slot. These move onto the reels to also increase your chances of bagging a payout, which, if you’re as lucky as the game name implies, could be a top payout of up to 20,000 times the bet per line. 

Mermaid’s Pearls

Mermaid's Pearls slot

Set on a 5×5 grid with 25 paylines to wager on, Mermaid’s Pearls entices players down to the sea bed. Dive down to where playful, fish-tailed women butterfly stroke their way through the game grid. Soon they reveal the most magical treasures when certain combinations of symbols make their way onto the reels. 

Chests packed with long-lost artifacts and bonus goodies are embedded into the ocean floor, each one packed out with prizes like Free Spins, Multipliers, and a colossal top prize worth up to 2,500x your stake. 

One of the most interesting features of this game is the Pearl Meter, which collects and stores all the pearls you score during the base game. It eventually unlocks a Ship Wreck bonus feature once it hits the 300 mark. Landing 600 pearls in the meter unlocks yet another action-packed bonus round called the Treasure Pearl. There you’ll instantly snag 20 Free Spins and a huge 5x Multiplier. 

With a whopping 3125 ways to win, Mermaid’s Pearls is sure to capture your heart as you dive for huge wins and the shinest of prizes. 

Scuba Fishing

Scuba Fishing slot

Another ocean-themed slot adventure by RTG that can “sea” players rack up a whirlpool of prizes while having a whale of a time doing so is Scuba Fishing. This exciting ocean slot features a classic 3-reel slot with 27 ways to win big. 

Head on down below on excursion to bottom feed for Jackpots and hidden treasures like Free Spins. You’ll encounter various marine creatures and fish ranging from oysters, jellyfish, anemones, and other colorful inhabitants of the ocean. The Shark, as menacing as he may appear, is actually your good friend in this slot and acts as the Wild. He’ll stand (or should we say swim) in place for all low-paying icons to help you hit bigger returns. 

The Scatter is the Scuba Diver, who, aside from taking snaps of you on his Polaroid when you achieve a winning line, activates the Free Games feature when 3 or more line up anywhere on the reels. Once active, you’ll instantly net 20 Free Spins. Wilds may also appear during Free Spins and appear stacked on the reels to increase your chances of hitting a big payout even further. 

As for the top prize, the maximum payout in this slot is a whopping 7,500 times your original stake. While there is no Progressive Jackpot up for the catch, players can look to bring some impressive payouts back to the surface with them in this slot.

Get ready to submerge yourself in the watery antics and fun of the Megaquarium. This 5-reel, 25-payline underwater party is packed to the max with bonus features and prizes to win on every fin. 

Set on a calming blue backdrop littered with exotic marine life and soothing soundscapes to immerse you in this magical aquatic adventure, you’ll come across symbols such as coral, treasure chests, clownfish, lionfish, seaweed, crabs, no fishing signs, and other things you would and wouldn’t expect to find rooted into the sea floor. 

You’ll receive a generous payout for combinations of three to five of these symbols when they appear on the reels. However, it’s the Bonus Games symbol and the Free Games symbol you’ll want to keep your fish eye out for, as these both activate two incredibly exciting bonus rounds. 

The Free Games symbol will only ever appear on reels 1 and 5, which awards 7 Free Spins with a x5 Multiplier if you land three or more anywhere. The Bonus Games symbol will only ever show up on reels 1, 2, and 3. And on the seventh spin, you’ll win 3 extra games and extended gameplay with the chance to win a Multiplier worth up to 200x your bet.

The Clownfish Wild replaces low-paying symbols while you play, doubling your prizes when it appears in a winning combination. Progressive Jackpots are also available to win in this exciting underwater escapade, which you can win on any random spin. 

Ocean Oddities

Ocean Oddities slot

Explore the sandy ocean floor and uncover a multitude of odds and ends and lots of winning possibilities in the Ocean Oddities slot, a high-volatility aquatic-themed adventure from Realtime Gaming. 

Featuring 25 adjustable paylines and 5 reels, this comical underwater journey is jam-packed with delightful surprises. Concealed behind each coral reef are exciting bonus features, free spins, and jackpots. What makes it so “odd,” you might ask? The fact you have a fish dressed in a cape and a snail riding a seahorse as some of the game symbols, for a start. You’ve also got strange, Wild West country music as the soundtrack. Oh, and a shark that barks like a dog as the Wild symbol. Rather odd.

We’re not quite sure what planet RTG was on when it came up with the theme for this one. Luckily, the developers kept the prizes and rewards relatively normal. Landing 3 or more pearl Scatters triggers 10 Free Games with the chance for retriggers, while the barking Shark (known as Rex) doubles your wins while acting as the substitute symbol. 

With a top reward of 2,500x your stake up for grabs, Ocean Oddities is a must-try game for any slots enthusiast looking for something extremely obscure but rewarding.
