Game information


Deep Descent


Relax Gaming









Deep Descent is a Relax Gaming video slot takes you on an underwater adventure. The playing field has 5 reels, 3 rows, with 243 ways to win in total. You can expand it further via the bonus rounds up to 3,125 ways to win, which is nice. There are both pluses and minuses to this slot and we’ll go through them all in this online slot review.

The action is highly volatile almost extreme. The hit rate is 25.66%, so you’ll get a win once per 4 spins on average. The max win of 18,814x is sweet, a jackpot worth playing for. If you like it, give Deep Descent a shot at one of our trustworthy mobile casinos online for slots players!

Betting Range, RTP & Symbols

The betting range is wide enough to allow everyone to play. The min bet is as low as $0.10, while high rollers can stake $50 per game round.

The theoretical RTP of Deep Descent is 95%. That’s a little bit on the low side, a full percentage point below the industry average. Remember, that’s 96% globally, so Relax Gaming didn’t stick to that in this one.

The theme is all about going underwater to see some fish. We’ve seen such themes before, but it’s never bad to see something similar again. At least these sea slots aren’t as overused as Egyptian-themed slots. The symbols consist of low and high pays.

The former is all about card suits. That means spades, diamonds, hearts, and clubs. The high pays have fish of different colors and one character symbol. Note that this character symbol pays out even in sets of two and more. Unfortunately, the production values of Deep Descent are hardly great. They are even slightly below average, well below par for top Relax Gaming slots. Our best legal offshore online casinos for Americans list slots like Wild Drops.

Bonus Rounds

Respin Wilds

The Wilds look like big boxes in Deep Descent. They always come with a number as well. This number signifies the number of respins they’ll give you. You’ll get those straight away and each will decrease the number on the box by one. It’s a fresh idea that works perhaps not as well as it could if it was in full flow.

Collectible Symbols

At the start of each spin, one of the symbols becomes a collectable. You’ll see it highlighted on the left side of the field, so it’s easy to identify. You’ll collect these symbols only if you manage to get them in a winning combination, however.

There are 3 levels in total and you can move through them by collecting the symbols. On the first level, your goal is to collect 7 symbols in a single spin. Respins count, though, so getting Respin Wilds makes things easier.

If you get the collection, you’ll move to the second level. Here, there’s an additional row and you’ll also get another Wild. This means 1,024 ways to win in total. You’ll have to collect 21 symbols in total to get to the third level, though. It’s the same thing again, another row and another Wild. In this setup, the number of ways to win increases to 3,125. You can’t go anywhere higher, though, that’s the game’s limit.



Deep Descent is more or less a missed opportunity. Relax Gaming wanted to go for something simpler with this release and they certainly did. They overshot the target by a decent margin, though. The end result is an overly simplistic video slot that feels shallow – ironic given the theme, eh?

The top jackpot is nice, sitting at 18,814x your bet. That’s the only positive that can allow the slot to stand out, though. The road is incredibly narrow as well, so don’t expect to win it anytime soon.

For a better alternative, we recommend you go for Just For The Win’s excellent Scarab Kingdom slot. It’s an Egyptian-themed affair, but with a bit greener scenery than you’d expect. It has plenty of bonus rounds as well.

You can collect Scarab symbols to get to them guaranteed, which is nice. You’ll get to the juicy bits through loyalty alone, so you’ll want to stay for a while. It’s volatile stuff, but the 30.99% hit rate will leave you unscathed. The production values are through the roof, so no complaints anywhere. Like Deep Descent, it’s available across our top European online casinos.
