Deep Descent

Relax Gaming sends Deep Descent into three descending layers of the same ocean, using rock formations, drifting clouds and passing fish rather than an explosion of colour to build its underwater mood. An orchestral score with layered bubbling effects sits over the visuals, aiming for a relaxed, sleepy atmosphere instead of the frantic energy typical of a high-volatility title.

The game opens across five reels, starting shallow at three rows deep for 243 ways to win, with standard 3-to-5-symbol combinations landing from the first reel outward. Low pays are card suits held inside bubbles, worth up to 0.8 times the stake for five of a kind; the premium tier runs through green, orange and red fish before reaching a diver character whose five-symbol combination pays 1.5 to 10 times the bet, and who also pays out from just two matching symbols. Wild symbols appear as golden boxes marked with a number, substitute for every paying symbol, and award a respin when they land, locking in place while the number they display determines what happens next.

Deep Descent's depth mechanic drives the whole session. Every spin selects a random low-value symbol to be the collectable of the moment, tracked on a counter beside the grid; using that symbol in a winning combination adds to the total. Reaching 7 collected symbols in a single spin or run of respins drops the game to its second layer, adding a row and a wild symbol and expanding the grid to 1,024 ways to win. Pushing the count to 21 collected symbols overall sends play to the third and final layer, where another wild joins the reels, a fifth row appears, and the win ways figure rises to 3,125.

Relax Gaming rates Deep Descent at 5 out of 5 for volatility with a 95% return to player and a 25.66% hit frequency, backing the slow-build design with numbers that favour patience over frequent small returns. Stakes run from 0.10 to 50 per spin, and the maximum win reaches 18,814 times the bet, achievable once a session has worked its way down through all three depth levels. Released in August 2021, Deep Descent asks players to build toward its biggest multipliers rather than encountering them from the first spin.
