Undine’s Deep Slot Review

Submerge into a magical world filled with majestic sea creatures like mermaids and seahorses. Take a deep breath and get ready to explore the bottom of the ocean to find long lost treasures. Will you be the one to succeed in spinning the underwater reels to riches?

Undine’s Deep features a simple yet elegant visual style. In the background you see a field of seaweeds moving by the waves as seahorses show up now and then. At the top, you’ll find the logo while right below it you see the reels encased in a slim dark marble border.

Mechanics-wise the slots reels start spinning altogether and stop individually in consecutive order. Symbols participating in winning combinations become animated. If you want to check similar titles we’d recommend Playtech’s “Ariana” and Pragmatic Play’s “Queen of Atlantis”.

Water-themed slots are one of the biggest attractions when it comes to online gambling. So without further ado let’s check out how the game works.

How to Play Undine’s Deep

The game has 3 rows and 5 reels as well as 10 non-fixed paylines. The controls are located at the bottom of the screen allowing the player to change the number of active paylines, select the bet amount, and enable the autoplay function among other options. The in-game menu offers even more customization possibilities.

Bet limits start at $0.01 (1 payline, minimum line bet) and are capped at $100 (10 paylines, maximum line bet).

The high variance of the slot means you won’t get regular wins but any potential wins will most likely be fairly rewarding. That said, the maximum win is $90,000!

Moving on to the symbols, there are 6 low-paying and 5 high-paying. Starting with the least rewarding, these symbols come in the form of card values 9 – A. The high paying symbols consist of a seahorse, a seashell, a jellyfish, a starfish, and finally an urchin.

Regarding the special symbols, you will find:

  • Wild – The slot’s wild is a goldfish. It can substitute for all symbols except for the scatter to form winning combinations. It doubles the win when substituting.
  • Scatter – The slot’s scatter symbol is the mermaid Undine. Getting 3 or more will activate the free games feature, awarding you 15 free spins with a 3x win multiplier.

Game Rules

Undine’s Deep Features

This certainly is one of the simpler Endorphina slots you can find. As a result, there only are two available bonus features.

Free Games

3 or more of the scatter symbol will activate the free games feature. The player will be awarded 15 free spins. All wins are multiplied by 3x.

This is where things become interesting as the scatter symbol can also appear during the free spins. In theory, this means that the free games feature can be retriggered infinite times.

Free Games
Risk Game

Similar to most of the provider’s other slots, Undine’s Deep offers you a chance to double your earnings after a winning spin. Every time you win you will be prompted to either take your win as is or to gamble.

If you choose to gamble, a risk mini-game will be triggered. During this, you will be presented with 5 cards. The first and only revealed card is that of the dealer.

Your job is to pick one of the 4 hidden cards and if your card is of a higher value than the dealer’s you win and double your win. You can continue gambling for up to 10 rounds. In the case of a draw, you have the choice to try gambling again or cash out. You can also cash out after any winning round.

If at any point you lose to the dealer, all your winnings up to that point including the bet of the spin that triggered the mini-game will be lost.

Finally, there is a chance the card you pick is a Joker. That beats all other cards. The dealer’s card can never be a Joker.
