Secrets of Atlantis Slot Game Review

In the introductory video at the beginning of the Secrets of Atlantis game, we start above water and slowly descend beneath the waves to the bottom of the sea.

The game is themed after the fabled lost city of Atlantis, said to have been submerged beneath the oceans, and behind the reels we can see the ghostly ruins of this mysterious city.

The three lowest value symbols are a crab, turtle and jellyfish, all of which appear to be floating within bubbles.

The higher value symbols are jewels to represent the three animals, a blue ‘jellyfish’ stone, a green emerald shaped to look like a turtle, and the ruby encased in crab shaped gold. Highest ofall the symbols is an oyster, open to display a giant pearl.

Mythical Mermaids

Befitting for a legendary city, there is a mythical creature swimming on the reels as well. This is the mermaid, who is also the wild symbol.

The mermaid appears full length, and if she does not cover the entire reel – which is four rows in height – she ‘nudges’ up or downs to fill the reel.

It’s a nice touch, and one with the possibility of granting some improved winnings. When you first play this game, you may be bemused by the fact that parts of the three centre reels appear to behighlighted in white.

In fact this is a crucial element of the game, as there are no traditional scatters or bonus rounds in this game.

Colossal Symbols

If the highlighted sections of reels 2, 3, and 4 all match, then you have unlocked the special feature of the game.

Note that all the symbols on the three centre reels must be highlighted, if even one is not then there is no bonus feature.

Assuming you have highlighted the three middle reels, then a colossal respin launches. The centre reels are transformed into one giant symbol, and it could even be the mermaid if you are reallyin luck.

When the colossal reel stops, one symbol may cover the entire 12 spaces, or you could see part of two symbols. In the case of the wild mermaid, if she only partially appears then she will nudgeup or down so as to cover the whole centre area.

Once the colossal reel has stopped, now reels 1 and 5 will spin. This is a win both ways game, so you could get a win from either direction. If the reel featuring the colossal symbol is fullyhighlighted, then you will get another re-spin.

The gratifying thing about this bonus feature is that it seems to occur quite regularly. For example, I got three colossal reels within the space of around 50 spins, and won a big prize with oneof them.

This is another fabulous looking game from NetEnt, and the colossal bonus feature is a nice change from the norm. The return to player is an extremely generous 97.07%, and there is a potentialcoin jackpot of 320,000 hidden in the depths if the colossal reels work in your favour.

This dreamy, underwater adventure is a winner, making the City of Atlantis slot game worth discovering.
