Mysterious Atlantis Bonus Features

After playing this game for quite some time, I’ve only found 2 bonus features in this slot. Let’s have a closer look at how these features operate:

Wild Respins

A compass is used in the game as the Scatter symbol. For Wild Respins to begin, it must land on the middle reel. You are given three wild respins, each with a randomly selected extra wild symbol. Dione, Melite, and Thalia are three different mermaids, each representing one of these respins. All symbols besides the bonus can be replaced by the Extra Wild symbols.

  • Initial Dione Respins: You get an additional Wild symbol on the reels for each respin. The original Extra Wild symbols are moved around as new reel positions are filled. The next Respin round then starts.
  • Melite Respins: The Extra Wild symbols expand to fill the entire reel during this respin round. With each Respin, the Extra Wilds also take up new positions. The Extra Wilds appear on the first and fifth reels for the first Respin. The Extra Wild will appear on the second and fourth reels for the second Respin. The Extra Wild on the third reel combines with another symbol for the third respin. The winnings are multiplied by 2x when this Extra Wild on the third reel forms winning combinations with other symbols.
  • Thalia Respins: The symbol on the reels with the highest frequency is chosen to change into the Extra Wild symbol during each Respin. The transformation does not include the Wild symbol.

Gamble Feature

After each win in Mysterious Atlantis, a gambling feature is activated. You can take the chance to have this feature double your winnings. You receive a face-down card on the screen as part of the gamble feature. You have to guess whether the card is red or black in color. The rewards for a correct guess are doubled. Your winnings are forfeited for a wrong guess.

Gamble Feature

You also have a Halve feature if you want to be safe. This lets you keep half your winnings and gamble with the other half.

RTP and Volatility

Mysterious Atlantis is a medium variance game with an RTP of 96.24%. The slot machine has some excellent gaming components that will give you good returns on your bet. Therefore, the fact that the RTP is above the industry average at 96.24% is unsurprising. Additionally, the medium volatility of the game ensures a balance of winning and losing spins.


The mythical underwater city of Mysterious Atlantis, which has been kept secret for many years, serves as the theme of the slot machine game. You can search the waters of this city for its undiscovered treasures in the game.

This theme has allowed for a spectacular development of the slot. The game’s background is made up of the underwater ruins of the legendary city of Atlantis. The reels are placed in a transparent environment. The middle reels are distinguished from the others by two lines of water bubbles.

We enjoyed the game’s graphics, which are of the highest caliber. For convenience, the game options are located under the grid of reels.

Symbols and Payouts

There are a total of 8 regular symbols in Mysterious Atlantis. To receive a payout, players must line up three to five identical symbols on the payline.

The high-paying symbols in this slot machine are the ship, fish, antique vase, and anchor. The best symbol is the ship, which will pay up to 100 times the stake for five of its icons on a payline.

The game’s low-value symbols include the Ace, King, Queen, and Jack card suit symbols. Low-valued symbols all have the same payout.

Wild, Scatter/bonus, and Mermaid Respins are the slot machine’s unique symbols in Mysterious Atlantis.

Tips & Tricks

You can win money if you line up matching symbols along a payline from left to right, with the first matching symbol appearing on reel 1 and subsequent matches on neighboring reels. Playing card symbols represent lower-value symbols on the reels of Mysterious Atlantis. When three matching symbols appear on a payline, your wager is returned; when five matching symbols appear, your wager is multiplied by ten.

You can win 25 times your wager by spinning five a kind of anchor and the green water carrier middle-value symbols. The top payout is 100x your bet for matching five sailing ships across a payline, which increases to 50x your bet for landing five fish symbols.

How to Play Mysterious Atlantis

Mysterious Atlantis has a wide variety of wagering options, which indicates that it is made to appeal to all different types of players. So, regardless of your risk tolerance or bankroll level, you can find a betting level that suits you. Play for as little as 0.20 per Spin or as much as 100.00 per Spin; then press the Spin button to see where the reels take you.

Use the Autoplay feature, which you can set to 10 to 1,000 automatic spins if you plan to play at the same stake level for a while. If you’re daring, there’s even an “infinite spins” option. However, you can stop Autoplay anytime by pressing Spin while running, giving you full control over the reels. The Gamble feature is not available when Autoplay is activated, so if you like the chance to double your winnings, you should steer clear of this choice.
