Darling, it’s better
Down where it’s wetter
Take it from me ♪♫♬

1. Queen of Atlantis by Pragmatic Play
Queen of Atlantis is a 5-reel, 4-row video slot game with 1,024 ways to win! There are no fixed paylines; at least 3 identical symbols on consecutive reels from the leftmost automatically reward a payout. Symbols include various sea creatures and hidden treasures, card suits, and the Queen of Atlantis herself. In her case and with the diamond card symbol, you’ll get a payout with just 2 symbols appearing consecutively. The Queen also appears stacked on all reels!
As with most slot games, there’s a Wild symbol that substitutes for all symbols except the two Scatters. During both Free Spins rounds, any Wild that appears on reels 2 to 4 will multiply the total win by either 2x or 3x!
The Golden Clam symbol with the white pearl is the game’s Scatter. 3 or more will trigger the Free Spins round, giving 8, 15, or 20 free spins with 3, 4, and 5 symbols, respectively. 3 or more during free spins will grant 5 additional spins! You may also win 5 more spins with one Scatter on reels 1 to 4 plus one on reel 5.
Super Free Spins
The Golden Clam symbol with the gold pearl is the Super Scatter, which only appears on the 5th reel during the base game. Any two or more regular Scatter symbols on reels 1 to 4 plus the Super Scatter on reel 5 will trigger the Super Free Spins feature. Before the reels spin, additional Queen of Atlantis symbols are added, giving more chances of winning big! 3 or more regular Scatter symbols during Super Free Spins will grant up to 25 more free spins! Like the free spins, you may also win 5 more spins with one Scatter on reels 1 to 4 plus one on reel 5.
Second Chance Bonus
Getting one Scatter anywhere on reels 1 to 4 plus a second on reel 5 will grant its own rewards as well! In the base game, it will give you the Second Chance Bonus. Here, you choose between three sunken ships to win Free Spins or Super Free Spins.
Queen of Atlantis welcomes you to explore the sunken kingdom, with all the special features to help you along the way. Play now on OppaBet!
2. Atlantic Treasures by Spinomenal
Atlantic Treasures has 5 reels, 3 rows, and 50 fixed paylines! The game’s medium-win symbols include a red-haired mermaid, pearl oyster, crab, starfish, and sea turtle. The low-win symbols are Jack to Ace card symbols. Additionally, there are special symbols as well, including Free Spins, Wild, and Bonus symbols!
Free Spins and Multiplier
3 or more scattered Free Spins seahorse symbols will trigger a number of free spins with their own bet multiplier. 3 symbols award 7 free spins and a x3 multiplier; 4 symbols award 12 free spins and a x5 multiplier; and 5 symbols award 15 free spins and a x7 multiplier.
King Poseidon himself appears as a Wild, replacing all symbols except Free Spins and Bonus. When 3 or 4 Wilds appear on a winning payline, the payout is immediately multiplied by x3 and x5 respectively. When a Wild appears on reel 2, 4, or both, the symbol expands to fill the entire reel, giving you a full view of the mighty Poseidon. Expanding Wilds can occur in both the base game and free spins.
Catch the Sparkle Bonus
A view of Atlantis serves as the Bonus symbol; 3 or more will trigger the Catch the Sparkle Bonus game. Here, you’ll see Atlantis’ silhouette in a shroud of darkness. Every so often, a small sparkle of light will shine through the darkness. You need to catch a number of sparkles – each one rewards its own payout!

3. Siren’s Treasures by Spinomenal
Spinomenal makes a second appearance on our list of favorites under the sea! Siren’s Treasures is a 5×3 reel video slot game with 50 fixed paylines. A Viking ship and some Viking treasures make up the medium win symbols, while Ten to Ace card symbols are low win. On top of that, you’ll also see a treasure chest as the Bonus, the red-haired siren as the Wild, and the handsome sailor as the Free Spins.
Mystery Symbol and Win Multiplier
After the reels in the base game stop spinning, you may encounter either or both of these special features. The Mystery Symbol is the siren up close and will uncover 1 random regular symbol. The Win Multiplier is a pink oyster and will open up to reveal a x2, x3, x4, or x5 multiplier at random!
The Siren Wild substitutes for all symbols except the Free Spins and Bonus. If 3 Wilds fill the entire reel, they’ll animate and expand to fill the entire reel, thus triggering a free respin while the Stacked Wild remains in place. In the base game, the Stacked Wild can only appear in reels 2 and 4. However, during respins, another Stacked Wild may appear on reel 3.
The Treasure Chest symbol activates the Bonus game. Here, you’ll need to choose 4 of 7 treasure chests. Each chest holds a cash prize at random.
Free Spins and Sticky Wilds
3 or more scattered Free Spins will reward 10 free spins and a x3 bet multiplier, regardless of how many Free Spins symbols trigger the feature. While reels are spinning during the free spins, a Sticky Wild may pop up at random. These symbols will remain in place after each spin until the end of the feature.
Siren’s Treasures takes you both under the sea and above land but either way, you’ll never be happier to see that mermaid! Play now on OppaBet!

Wild Symbol Multiplier
The Wild symbol is a scary-looking fish and substitutes for all symbols except the Scatter and Bonus. During the free spins, the Wild also triples all wins when substituting in a winning payline. Your chances of landing a Wild in free spins are higher, too!
Scatter Free Spins
A busty mermaid acts as the game’s Scatter symbol; 3 or more will reward up to 23 free spins. To determine the number of free spins you’ll be playing with, choose one of the five mermaid dancers that pop up on the screen.
King Neptune Bonus Game
3 King Neptune Bonus symbols on reels 2, 3, and 4 will activate the Bonus Game. Before the game starts, choose between black or red. Once you’ve chosen, King Neptune will pull out 9 crabs from the hermit shell. The more crabs that match the color you’ve chosen, the bigger your bonus prize will be! You could win up to x500 of your bet!
After each win in the base game, you can opt to gamble your winnings. All you need to do is guess whether the next hidden card will be red or black! Choose correctly and double your winnings; choose wrongly and lose it all.

A red-haired siren’s face is the base game’s Wild symbol and substitutes for all symbols except the Free Spin. When she appears at the top position of any reel, she will reveal her entire body to cover the whole reel. Additional pays will be rewarded from this Expanding Wild.
When you see a golden octopus holding up an orb, that’s your Free Spins symbol! 3 or more of these will reward a number of free spins depending on the number of triggering symbols. 3 symbols will reward 14 free spins; 4 symbols will reward 25 free spins; 5 symbols will reward 36 free spins!
Expanding Sticky Wilds
Yet another beautiful (this time purple-haired) mermaid is a Wild symbol during the Free Spins. Whenever she appears on screen, she expands in two different directions and stays in place for the next spin.
