Secrets of Atlantis is a beauty of a game, its relaxing music the perfect aural backdrop to your gaming session and the symbols and graphics transporting you to a serene underwater landscape.

The reels are inhabited by sea creatures and bejewelled symbols, giving players the sensation that they are discovering the secrets of these uncharted waters as they play.

You’ll see plenty of bubbles, pearls and gems on the reels but the real treasure is the mysterious mermaid. When she shows up, you can be sure the reels are about to spin in your favour.


Packed with great features and a dreamy soundtrack, Secrets of Atlantis is set to become a firm favourite with slot maniacs. The reel layout will be familiar to most but it’s the game features that really make this title from NetEnt stand out.

Let’s take a look at this slot’s special features, which we’re sure you’re going to enjoy while playing this nautical slot.


The Highlight feature can randomly highlight symbols on reels 2 to 4, activating a Colossal symbols Re-Spin.


During a Colossal Re-Spin, reels 2 to 4 transform into a single reel with giant symbols. This 3×4 symbol block can only appear when the Colossal Re-Spins feature is activated.

If the reel with the Colossal symbols is fully highlighted, this triggers an additional Re-Spin.


The mermaid symbol comes in here, triggering the Nudge Wilds feature. The symbol may be fully or partially displayed on the reel but it doesn’t matter – once it appears, it will be nudged upwards or downwards to take up the whole reel. When a Colossal Stacked Wild lands partially on the reel during a Re-Spin, it too will be nudged upwards or downwards to cover the whole reel.


Coin values and bet limits are both adjustable on Secrets of Atlantis. Set your coin value to a minimum of 0.01 or a maximum of 1 and choose from a bet limit range between €0.20 and €200. There are 10 default bet levels in total.


The maximum default win on a single bet way or bet line on Secrets of Atlantis is €4000 or 4000 in coins.
