Mysterious Atlantis slot has the theme of the mythical underwater city, which has stayed hidden for several years. The game allows you to explore the waters to find the hidden treasures of this city.

Owing to this theme, the slot has been spectacularly developed. You will find the remains of the mythical Atlantis city underwater, which forms the background of the game. The reels are set in a transparent setting. There are two lines of water bubbles present to distinguish the middle reels from the rest.

We liked the graphics of the game, which are showcased in top quality. The game settings are present under the reels grid for easy access.

Mysterious Atlantis has a total of 8 regular symbols in the game. Players have to land a combination of 3 to 5 same symbols on the payline to grab a payout.

The ship, fish, antique vase, and anchor form the high-paying symbols in this slot. The ship is the best symbol paying up to 100x the stake for 5 of its icons on payline.

Furthermore, there are card suit symbols of Ace, King, Queen, and Jack, which form the low-value symbols in the game. All the low-valued symbols pay equally.

The special symbols of the Mysterious Atlantis slot are Wild, Scatter/bonus, and Mermaid Respins.

Bonus Rounds & Free Spins

Wild Respins

The Scatter symbol of the game is represented by a compass. You have to land it on the middle reel to activate Wild Respins. You get 3 Wild Respins which are played with a randomly chosen Extra Wild symbol. These respins are represented by 3 different mermaids – Dione, Melite, and Thalia. The Extra Wild symbols can replace all symbols except the bonus.

  • Dione Respins: It begins with 3 Extra Wild symbols. For every respin, you gain 1 Extra Wild symbol on the reels. The original Extra Wild symbols shuffle to take new positions on the reels. Then the next Respin round begins
  • Melite Respins: During this respin round, the Extra Wild symbols become expanded to cover the entire reel. Furthermore, the Extra Wilds move to new positions with every Respin. For the first Respin, the Extra Wilds appear on the 1st and 5th reels. For the second Respin, you will see the Extra Wild on the 2nd and 4th reels. For the third respin, the Extra Wild merges into 1 symbol on the 3rd reel. When this Extra Wild on the 3rd reel substitutes other symbols to form wins, the winnings are multiplied by 2x
  • Thalia Respins: During every Respin, the symbol with the highest occurrence on the reels is selected to transform into the Extra Wild symbol. The Wild symbol is not counted for the transformation.
