There are pros of this slot:
it is a high RTP slot (97. 07%)
top-notch quality of the sound
HTML5 is supported (it is available on mobile devices)
There are cons of this slot:
quite an ordinary theme (even though, it is well-implemented and has its own interpretation)
low possible winning (but, on the other side, as you could get that if the volatility level is low and your winnings will appear more often)
there is no free spins multiplier
Now let’s summarize the information that we have. Secrets of Atlantis is a perfectly-made slot developed by NetEnt provider. Alongside with a good design, it also offers a high RTP and a low volatility level which is quite a rare combination. Moreover, visuals and audio effects have high quality and help to dive into the atmosphere of the slot’s theme which is an undersea world.
As for me, I see only one disadvantage, it has tricky re-spins mechanics that is surely a matter of taste. And what is for the low volatility level, I like such, so to say, safe games, but maybe the low possible winnings are not your choice at all.
So, I would recommend this slot to an average player, but the decision is yours.
