A Review of the Slot Game Wild Stack Frenzy

There are a wide variety of mining games accessible, and if you’ve played enough slots, you’ve probably participated in at least one that takes you deep into the earth to smash rocks in quest of valuable minerals or metals. Have you ever gone spelunking on the reels? Thanks to Yggdrasil Gaming and their slot machine Wild Stack Frenzy, you’re going to. Those who enjoy exploring underground caverns (or “spelunking,” if you must know) would have a blast in the Wild Stack Frenzy universe. You’ll find wild Super Stacks with multipliers, avalanching dropdown wins, free spins, and a bonus purchase in these caverns of a lifetime.

The world of Wild Stack Frenzy is a visual treat, and I encourage you to return there. Explorers down here will find enormous dinosaur bones, crystals, and mushrooms of colossal proportions imbedded in the cave walls. Wild Stack Frenzy has an element of the primeval and the mysterious about it, with prehistoric allusions and some of the typefaces reminding one of Raptor DoubleMax. The assessment was conducted before the release of Wild Stack Frenzy, so players will be pleased to learn that the game will have two “graphical improvements that no one sees coming” and more sound effects. The aesthetics aren’t terrible, so we’re curious to see how they develop.

There are 20 paylines in Wild Stack Frenzy, and players may choose to have them pay either left to right or right to left. Winning combos can originate from either the left or right side of the grid. The mathematical model is very risky, with a default RTP of 96% and a hit frequency of 35% supported by a cascading dropdown win concept. But you should know that models with a lower expected return have also been developed. Players may start their cave exploration with a bet of 10 pence or more, up to £/€200, and 60 times their initial wager can be spent on free spins.

Card suits (clubs, spades, diamonds, and hearts) etched on rocks serve as the game’s low-pay symbols, followed by the shell, rib bones, claws, and jaws, which have a little more occult feel. A victory with 5 low-pay symbols pays out at 1x the wager, while a win with 5 OAK premium symbols pays out at 2x to 5x the wager.

Video Slot Functions in Wild Stack Frenzy

Since line wins aren’t worth a lot of money on their own, you’ll want to use Wild Stack Frenzy’s other features like avalanches, Super Stacked wilds, and free spins to boost your bankroll.


After a player collects a win, the winning symbols vanish from the screen and the reward is collected. This clears the way for new symbols to fall into play, increasing the number of possible outcomes from a single spin. The total win is paid out once the avalanche process has run its course and no new combinations may be formed. A stack of wilds hovers over a random reel, waiting to fall into place following a victory (it appears on the first spin).


In Wild Stack Frenzy, the wild symbols are Super Stacked across the reels and feature a numerical value. If the wild contributes to a victory, the multiplier shown will be applied to that win. Super Stacked wilds last for 3–6 spins during the main game and 3–10 during the free games. Each wild stack has a multiplier of x1 in the main game and can increase by +1 to x6 or x10 in free spins. The wild card can be used in place of any non-wild pay symbol.

Bonus Turns

Free games are triggered by getting 3, 4, or 5 scatter symbols anywhere in the main game. The bonus round can be retriggered while playing the free games. As was previously established, the Super Stacked wilds in the free spins bonus round are far longer than those in the main game.

Slot Game with Wild Stacks and a Verdict

After everything was said and done, I had to admit that Wild Stack Frenzy gave a heaping helping of fun. This is hardly the type of ground-breaking slot machine that Yggdrasil Gaming probably whipped up in its lab a few years ago. Wild Stack Frenzy, on the other hand, keeps its nose to the grindstone and goes to work activating a solid suite of features within a fantastic underground realm replete with bones, crystals, and enormous, maybe magical mushrooms.

What works well is that there is a nice chonk of avalanche action going on, which means that it is possible to score really long streaks of consecutive wins from a single spin or a free spin. Wild Stack Frenzy’s aesthetic movements are delightful, attracting players with its rich visuals and engrossing audio while symbols are being smashed and replaced.There’s no denying that Wild Stack Frenzy is a visually pleasing title. The Super Stacks of wilds become relevant throughout the avalanche; you shouldn’t forget about them, as their multipliers are crucial to boosting normal line wins. However, during the standard game, stacks are only guaranteed to go as high as 5 high, while during free spins, they can go as high as 10. If my recollection serves me correctly, a new stack of 3 wilds may arise on top of an existing stack of 3 wilds, resulting in the beginning of a new multiplier trail. That’s just the way it is with slot machines, I guess.

Wild Stack Frenzy’s spelunking feature is a nice change of pace from the usual underground mining, and the game’s 5,000x bet jackpot isn’t exactly mind-blowing, but it’s respectable, and the super stacks of wilds help a lot.
