Sirenas is a Novomatic-powered slot with 5 reels and 10 paylines. Playable from 40p to £100 per spin across desktop, mobile and tablet devices, this mermaid themed game takes you on an underwater adventure in search of the treasures that the beautiful mermaids hoard.

With an enchanting soundtrack, it’s set underwater – with fish swimming across the reels, you will come across lucky red 7s, cherries, oranges, lemons, grapes, sailing ships and anchors on the reels. The highest value symbol is the Sirenas logo which rewards you with 5,000 times your line stake for 5 on a payline.

There’s a Starfish Bonus feature which is randomly triggered in the base game – this may occur after a spin without a winning combination. You will then either win 10 free spins or a cash prize.

The other way to trigger the Free Spins feature is to get 3 or more Sirena (mermaid) wild symbols anywhere on the reels. As the wild, she substitutes for all other symbols. If you manage to get 5 on a payline, you will be rewarded with 500 times your stake. You will also receive 10 free spins.

Now, look out for the bonus symbol (clams with ‘Bonos’ written on them) as 3 of them on reels 1, 3 and 5 will trigger the Crab, Fish or Chest Bonus features. Look out for the clam above the reels which will trigger the corresponding feature. The good news is that there are standard and super versions of each bonus feature!

Crab Bonus feature – in the standard Crab Bonus feature, 1 crab will blow bubbles and give you cash prizes or free spins. In the Super Crab Bonus feature, all 3 crabs blow bubbles to give you more prizes and/or free spins.

Fish Bonus feature – the standard Fish Bonus feature gives you free spins or a cash prize for fish caught. The Super Fish Bonus feature sees 3 fish being caught with all prizes/free spins totalled.

Treasure Bonus feature – in the standard Treasure Bonus feature, you simply pick a treasure chest to win a cash prize or free spins. In the Super Treasure Bonus feature, you will get the contents of all 3 treasure chests.

All cash prizes are added to your balance with free spins added in the Free Spins feature that you are already playing. Despite the graphics being simply Novomatic standard, the way to win big is via the Free Games feature where the pick me features within it can be quite rewarding due to additional free spins and cash prizes. Variance wise it’s in the middle with more volatility available in the classic Lord of the Ocean.
