Wild Stack Frenzy Slot Review 2024

Today’s word of the day brought to you by Collins Dictionary is spelunking – a verb defined as “the leisure activity of going into underground caves and tunnels.” Amazing what slots can teach you.

It’s clearly what Swedish outfit Yggdrasil Gaming had in mind when designing their colourful October 2023 release Wild Stack Frenzy – a game evoking a measure of magic set several hundred metres below sea level – and way in the past.

So if you’re in the mood for some frenzied spelunking, grab your hard hat and get ready to burrow into subterranean labyrinths as we seek to establish how the game fares.

Wild Stack Frenzy Base Game

Wild Stack Frenzy Base Game and Features

Upon first inspection, it seems like prehistoric animals, or as Yggdrasil put it, “biological wonders” of some kind, have beaten us to our destination by several hundred, or thousand, or even million years, indicated by skeletal leftovers scattered around and adorning the game’s 5×3 grid. Taking the suspiciously large mushrooms out of the equation, it’s a scene that wouldn’t look totally out of place during an episode of The Flinstones. Wiilllmaaaaa!

And is that a T-rex mandible to the right? Hard to say for sure, but it helps wind back the clock to a simpler time when cave exploration was likely performed with survival in mind, rather than fuelled by leisurely motives. Wonder what caveman existing aeons ago would have made of all this on-reel spelunking lark. Presumably, they were too busy dodging the attentions of woolly mammoths and the like to even care.

Anyway, back to matters at hand, and Wild Stack Frenzy is a highly volatile, pays-both-ways game offering 20 fixed pay lines that sees winning combos start at either outermost reel.

Pay symbols are split between low-paying playing card suits encrusted into rocks a little like runestones, and a shell, rib bones, claws and jaws used to represent the premiums that fetch a max 5x the stake for 5OAK wins. Values that are on the low side, no doubt, but a suite of features is on hand to pick up the slack, starting with Avalanches.

Avalanches blast symbols belonging to winning combinations from the reels, prompting more to fill their positions from on high. This leads to potentially lengthy snowballs of wins, only ceasing when no new winning lines materialise.

The Wild symbol takes on added potency in Wild Stack Frenzy. Not only does it replace all other regular symbols, but also appears in Super Stacked form while displaying a multiplier that gets applied to any wins it contributes to. During the base game, Wild symbols can land between 3 and 6 rows high, expanding up to a max 10 rows high in the bonus round.

Finally, for each additional wild placed on top of an existing wild, the multiplier augments by 1x, topping out at 6x in the base game and 10x in Free Spins.

Wild Stack Frenzy: Our Verdict

As far as games of this ilk go, Wild Stack Frenzy has to rank as one of the most creative, enjoyable, and unexpected contributions we’ve encountered. Slots have a habit of throwing up surprises, and so it was with this Yggdrasil entry – beckoning intrepid adventurers deep down below to discover a wondrous cave replete with glowing, lifesize mushrooms, glistening gems and even animal bones dotted about to up the surreal factor.

Sure, the game’s 5,000x max win won’t exactly set the gaming world alight, and its features are ever so slightly underwhelming, but it’s easy to say past those minor gripes when the provider is capable of immersing players in such a magical game world that sparks the imagination, helped by some mesmerising visuals.

For an underground adventure of discovery enveloped in an air of magic and mystique, Wild Stack Frenzy is well worth a look
