Deep Descent Online Slot Review

Take an in-depth look at the Deep Descent online slot from Relax Gaming. Cartoon fish and a high-paying diver appear across 5 reels, and you have 243 different ways to line them up for a win. Respins with sticky wild symbols help to create extra winning combinations, and you can explore the virtual ocean as extra rows unlock.

You can grab a win of 18,814x your wager from the sea floor. Deep Descent is a high volatility game with average returns of 95% and you can play desktop and mobile versions at our favorite New Jersey and Pennsylvania slots sites.

How to Play the Deep Descent Slots Game

A gentle, tinkling tune plays out as the reels spin, accompanied by the sounds of the ocean. It’s a peaceful environment, filled with 3 brightly colored fish and a Jacque Cousteau-type character peeking from the porthole of his submarine. Playing card suit symbols also feature here, and while they don’t look as nice as the fish, they are the trigger to expanding the number of rows and winning ways.

The game starts just below the surface, in light blue waters that splash on rocks in the background. Head deeper with the extra rows, and you enter forests of seaweed and a dark cave. You can enjoy this aquatic scene on PCs, iOS, Android, or Windows mobiles.

Relax Gaming’s Deep Descent slot offers a wager range of 0.10 to 50.00, and it’s easy to choose a level with a click on the stack of coins on the controls. A Spin button sits below this, and you descend the controls to find an arrow tab which spins the reels automatically.

The 3 little lines right at the bottom take you to the paytable of the Deep Descent online slot. It shows you how much you win at your chosen wager level from each symbol when you match at least 3 of the same kind on any row, starting from the left reel.

Respins & Other Deep Descent Online Slot Features

A golden ‘W’ is the wild symbol of the Deep Descent slots game. It doesn’t pay any prizes on its own, but does what wilds are known for, and acts as other symbols if can then complete or improve a winning combination.

Whether it’s part of a win or not, the wild then locks in place as other symbol position respin for free. The number of respins is revealed on the wild, with a maximum of 5 rounds, while any new wilds also lock in place and award extra respins.

A Collection feature is active at all times. A porthole to the side of the reels displays a random low-value symbol on each spin. If the symbol is part of a win, it collects in the meter and once you have 7 of a kind in there, you start the descent to the ocean floor.

There are 3 levels here. The first is where the basic respins play out and at the second level, an extra row of symbols is added to the mix, along with the wild on each respin. Like some of the best slot games, you now have 1,024 different ways to win. Collect 21 symbols in the meter and you reach the third and deepest level, where a fifth row of symbols gives you 3,125 winning ways. Another wild appears in the respins, adding extra rounds to continue the sequence.

Once the respins come to an end, you return to the shallows and start all over again, hopefully with a generous bounty from the depths.

It’s possible to win up to 18,814x your wager from the Deep Descent slot. At the maximum wager of 50.00, you can dredge up a prize of 940,700.00 over a long enough series of respins. It’s a high volatility slot with a disappointing average return to players percentage of 95%.

Our Deep Descent Slot Rating

That low payback percentage is the only real issue we have with the Deep Descent slot, as high volatility games should really return 96% or more to players. But it’s a cheerful game with lots of colorful symbols and an exciting respins bonus feature.

Getting to the bottom of the ocean over a series of respins won’t always happen, but with extra wilds and rows, once you begin the descent, it becomes easier to continue the round. See if the Deep Descent slot sinks or swims when you play it at the top Relax Gaming online casinos, and don’t forget to claim the biggest welcome bonuses when you sign up.


Wild symbols award between 2 and 5 respins of the Deep Descent slot reels. You collect symbols to descend down a further 2 levels, where it becomes easier to continue the respin feature. Once you run out of respins, you return to the base games at the surface.

The Deep Descent slot has a maximum win equal to 18,814x your wager, or 940,700.00 at the highest possible stake. That’s a generous multiplier and you can win this if the respins carry on for long enough.

There are no fixed paylines in the Deep Descent slot. You win from matched symbols on any row from the left reel, and there’s an initial 243 different ways this can happen. In the lower levels, you get 1,024 and finally 3,125 ways to win.

The Deep Descent slot has a high level of volatility so the reels may spin for longer than average between wins. Low volatility slots pay smaller prizes, but more frequently, while medium volatility games, as the name suggests, are somewhere in the middle.

You can play the Deep Descent slot for just 0.10 per spin. The maximum is 50.00, which is a wide enough range to cover most budgets, but perhaps a little low for high rollers. There are many options between these limits and it’s an easy game to set up and play.

The Deep Descent slot has an underwater theme and features a variety of colorful fish symbols against an ocean backdrop. A diver in a submarine also appears, plus a golden wild symbol. Playing card suits in bubbles pay smaller prizes.

Games with an underwater theme such as the Deep Descent slot are very popular. Similar slots include Fishin’ Frenzy Megaways from Blueprint Gaming, and Blue Fortune from Quickspin. You’ll find these and more at our favorite online casinos.

The Deep Descent slot comes from Relax Gaming and joins a sought-after range that includes slots such as Marching Legions, Wild Chapo, and Money Cart 2 among others.

Relax Gaming launched the Deep Descent slots game on August 3rd 2021.
