Deep Descent

Deep Descent by Relaxgaming is a video slot set in a tranquil underwater world where players descend through three depth levels in search of hidden ocean treasures. The game begins on a 5-reel by 3-row grid offering 243 ways to win, and as you collect special symbols the grid can expand by unlocking extra rows and wilds up to a 5-row format with 3,125 ways to win. Each spin one low-value symbol is randomly chosen as “collectable,” and when that symbol appears in a winning combination it fills a meter. Gathering seven of these symbols unlocks the second level with a fourth row and an additional wild; collecting 21 advances you to level three, adding a fifth row and yet another wild. Wild symbols substitute for other regular symbols and trigger respins: when a wild lands it locks in place for a number of respins displayed on the wild (between two and five respins), and resonates with extra wilds to extend those respins further. The wild respins persist as long as there is at least one wild symbol on the board. Deep Descent does not include free spins rounds in a traditional scatter-triggered sense, nor is there a Bonus Buy option. The game’s maximum win potential reaches up to 18,814× the stake when you reach the deepest level with full features active. The theme is soothing and aquatic, with symbols including fishes and card suits styled as bubbles, wilds that sparkle and collectables that map your descent in a layered, progressive format.
