Undine's Deep review: introduction

Undine is a mythological figure originating in Europe. The stories tell of a water nymph who fell in love with a man and sold her soul to become human and join him on the land; however, she would die should he be unfaithful.

In this underwater adventure slot by Endorphina, you will join Undine as she searches to find a way to join her human love on the land. The 5x3 reel grid provides 10 paylines and is filled with sea life to help this water nymph on her quest.

To win in Undine’s Deep, you will need to land combinations of three+ matching symbols along a payline, starting on the leftmost reel. Undine’s golden fish friend acts as the wild symbol in this slot, capable of helping you on your quest by substituting for any other symbol - excluding the scatter - to help you win bigger and better prizes. He will even double your winnings when he is part of a winning combination!

Undine herself is the scatter symbol in Undine’s Deep. Find three+ of her likeness in any position on the reels to trigger the free spins bonus round in this mythology themed slot. We will look at this round in the bonus features section of this slot review.

In addition to the base and bonus games, Undine’s Deep offers the chance to gamble your winnings in a double-or-nothing gamble feature in which you need to beat the dealer to double your winnings. If you don’t beat the dealer, you lose the lot!

Theme, graphics & soundtrack

For a slot based on the story of a water nymph, it makes sense for Undine’s Deep to be set beneath the seas. This simply designed slot allows you to see sunlight piercing the water, with seaweed growing up the sides of the transparent reels. The symbols in this slot include a variety of sea creatures, such as a starfish and jellyfish, to help you on your quest. The soundtrack is dark and filled with suspense, which is the perfect addition to the storyline of a water nymph who may lose her life.

Conclusion

Overall, we really enjoyed Undine’s Deep. It is fairly unusual to find European mythology making it into the world of online slots and we thought Endorphina did a great job of bringing this story to life. We are still not completely sold on the control layout Endorphina uses, but the graphics, soundtrack and winning potential certainly make up for it! We were particularly impressed by the prizes available when wilds come into play in this slot, and the 3x multiplier in the free spins round gave us plenty to be happy about.
