How to Play

Playing this slot is quite simple:

  1. Find one of the best online casinos on our site
  2. Make your choice by clicking on the button and going to the site
  3. Sign up if you think it is necessary.
  4. Start enjoying the game

The Deep Descent video slot has an action-packed beginning with 5 reels, 3 rows, and up to 3,125 different chances to win. Bet levels here vary from €0.1 to €50 for each spin. To change your bet amount, use the “+” and “-” buttons next to the box labelled Total Bet.

Deep Descent RTP and Volatility

7.5 

Deep Descent offers 95% RTP and high variance.

The Return to Player percentage in Deep Descent is 95%, significantly lower than what we often find in slots developed by Relax Gaming. The percentage is, therefore, a little disheartening, given that slots produced by this manufacturer often have payout rates greater than 96%.

This is a highly volatile slot game in terms of its potential payouts.

Theme

9.2 

The game's concept is based on a fishing theme, and it takes place in the open ocean, where the player and a seasoned angler go on an expedition to fish. There is a school of fish swimming erratically in the backdrop of the reels, and the actual valuable fish have been placed on the reels themselves in this game. Music that is both fascinating and evocative is played while the submarine is spinning, which helps to generate the ideal feeling of excitement for this underwater excursion.

Here you will find regular symbols stylized for the underwater world. Thus, the clubs, diamonds, hearts, and spades are in water bubbles and represent the lowest elements. Green, yellow, and red fish are middle-pay symbols with the highest payout of 2.5x the bet for a 5-of-a-kind line. And the explorer pays the most – 1x, 2x, 4x, and 10x.

Wild symbols will stay in position and offer re-spins whenever they occur on reels. Re-spins are awarded based on the current number indicated on the wild card. Therefore, the more Wilds you get, the more respins you get. Re-spins are feasible in enormous numbers because of the unique number assigned to each wild.

Bonus Rounds & Free Spins

Wild Respin

Relax Gaming's Deep Descent slot features a respin function that keeps players entertained as they spin the reels. To add another degree of complexity to the games, we've never seen Wilds activate respins with a counter before.

Deep Descent Progression

As an added perk, the Descent Bonus is lovely. Expansion reels, which have been popping up in an increasing number of slots, get a makeover in this new variation. While not a free spins bonus, it offers enormous earning possibilities and extends your respin for a long time. This function may be a little more challenging to activate for you, though. To win with 7 low-paying symbols, you'll need patience. And we are not talking about 21 elements.
