Undine's Deep Slot is currently available only in free play mode in your country.

Undine’s Deep is a colourful 10-payline video slot which runs on the Endorphina software platform. This underwater-themed game’s most important symbols are the Gold Fish, which is the wild card and the scatter in the form of a Mermaid. Players can try the slot on this page for free or choose any of the featured Endorphina casinos to play the game for real money.

In order to dive in and explore the splendour of the deep waters, players should adjust their bet first. The coin value, ranging from 0.01 to 5, is altered by pressing the coin-shaped button. The total bet is regulated by clicking the up and down arrows in the lower left corner and the number of paylines played is selected by choosing to click on “Lines”. The “Spin” button initiates the game and “Auto” offers players the option to spin multiple times without interruption.

Clicking the “Take Risk” button may lead to a boost of one’s winnings. As the dealer reveals their card, the player picks one of the 4 face-down cards. If the player’s card is higher than the dealer’s, the sum is increased. If it is lower, though, the amount is lost and the gamble round is over. Players can terminate the feature and save their winnings by pressing the “Take Win” button.

If 3 or more scatters appear on the reels, 15 Free Games are triggered. During this feature, all wins are tripled. Free Games can be retriggered.

The jackpot of 9000 coins will be awarded when 5 wilds emerge on any activated payline.

I've played this slot for a bit over 2000 spins now and I enjoy the simplicity of it, it's fast, works well and gives a solid gambling experience in that way.

DISLIKED

In those 2000+ spins I got 0 bonuses and 1 win that was 10x or more, seems to be very low odds.

“Undine's Deep” is a slot manufactured by the company “Endorphina” whose theme is based on a mythological character like a mermaid that inhabits the deep sea and whose blue design conveys calm and provides a relaxing environment to the player.

Indeed, calm and patience are qualities much needed when we are facing a video slot provided with only 10 pay lines and where they are only validated lines formed from left to right; slots of this type are usually not so dynamic and, in some cases, also boring, and in an attempt to neutralize these weaknesses, Endorphina has decided to include a wild symbol represented with the image of a goldfish, which on one hand is a very active symbol that sometimes makes even massive incursions on the reels and, in addition, this wild has the power to double wins when it helps to get any hit.

There is also a round of 15 free games where all wins are multiplied by 3x; however, in my opinion, this pair of features fail to be sufficient to make “Undine's Deep” in a video slot really interesting because, even with their help, we usually get very long losing streaks and, somehow, free spins inherit the same low hit average shown during the base game.

I think a bonus round would not suit bad this slot; I also think that perhaps paying for the lines formed in both directions, from left to right and right to left, it would be a good alternative for improving hit average in this slot.

On the other hand, if it weren’t so hard to get the three scatters necessary to trigger the round of free spins, it is possible that my image of this game would be more positive, however, definitely I have not managed to connect very well with this video slot and what I think is that “Undine's Deep” is not a bad game but not very good either, in other words, this is another mermaids themed slot; not my cup of tea, as the English say.
