The Wild Stack Frenzy Slot Game

For those who’ve played slots from Yggdrasil Gaming before, you already know that most of them use top-quality visuals. As such, you should expect a visually appealing atmosphere when loading this particular game.

Access the Wild Stack Frenzy demo at no cost here at GoodLuckMate! That way, it’s possible to practise the gameplay alongside this review.

The game loads into a cavern made from crystalline walls packed with humongous dino skulls beside other pre-historic elements. But the gameplay itself isn’t set in the primordial period. Instead, the crisp visuals and rhythmical sounds are a sign of modernity.

When playing, I found the animations to be the most interesting design feature.

All the Wild Stack Frenzy slot machine controls rest underneath the reels, making it seamless to navigate during your gameplay.

Symbols and Payouts

The game uses a total of 10 symbols, which is the standard number for most online slots. As such, you should expect a typical winning process when spinning the reels. Also, it’s worth mentioning that all the Wild Stack Frenzy online slot game symbols are thematic.

Every player’s objective is to align 3+ of the same symbols consecutively from the furthest left or right columns and along valid paylines to trigger payouts.

Wins are paid dynamically, depending on the current stake!

The low-win symbols are stone-crafted signs culminating into a Club (Green), a Spade (Blue), a Diamond (Purple), and a Heart (Red). When you hit up to 5-of-a-kind, they give out 0.2x to 0.5x the total bet!

As for the high-paying symbols in the Wild Stack Frenzy slot, they are the Shell, Rib Bones, Claws, and Jaws. As for these, they pay up to 1x, 1.5x, 2x, and 2.5x the bet for at least 3 of each.

That’s it for the regular symbols. However, users should also watch out for the Wild Crystals, which typically substitute for all regular icons besides being super stacked.

Also, the Mushroom ‘Free Spins’ symbols can appear and trigger the bonus games. Come along with me to the next segment of this Wild Stack Frenzy slot review for the complete bonus details!

Wild Stack Frenzy Slot Bonus Features

The game’s 5,000x stake max win is achievable, thanks to the Avalanche, Wild Stacks, and Free Spins features.


Like most Yggdrasil slots, this game adopts a cascading system where winning games can increase payouts. Whenever you manage a win, the paying symbols explode from the screen, leaving room for new icons to cascade into and grow the potential win.

This Wild Stack Frenzy bonus progresses until no more new paying icons appear on-screen. At this point, the total win pays out.

Wild Stacks

All Wilds appear as Super Stacked symbols, covering 3-6 rows tall in the main game and 3-10 positions in Wild Stack Frenzy free spins. Each stack begins with a 1x multiplier, increasing by one (1) up to 6x or 10x in the base and bonus rounds, respectively.

The higher the segments, the higher the attached multiplier, which applies to any win the multiplier is a part of.

Free Spins

Hit 3 to 5 scatters for seven (7), nine (9), or eleven (11) Wild Stack Frenzy free play rounds, respectively. It’s possible to retrigger more games in the bonus rounds. Also, the free spins are played with the same stake and lines as the triggering game.

Buy Bonus

If you have enough bankroll, you can pay 60x the bet for an instant trigger of 7 free plays from the base game.

How to Win at Wild Stack Frenzy Slot

This video slot is not a complicated affair, meaning it should be easily understood by every player. Nonetheless, I encourage you to practise the Wild Stack Frenzy free demo from before playing with real money.

After launching the game, it exposes a standard 5-reel and 3-row layout. Digging deeper reveals that the grid plays on 20 fixed paylines paying both ways.

As such, the aim is to land 3+ identical symbols from both left to right and vice versa.

Wild Stacks always appear above a random column, ready to drop in a cascade after a payout.

Before playing any round, choose between the €0.20 and €200 stake range. Afterwards, press Spin for a single Wild Stack Frenzy slot game round. Otherwise, the Autoplay option triggers preselected auto-spins that are limited by optional settings.

While the Speaker icon regulates the game’s sounds, using the Menu key reveals other options, including the paytable, system settings, and game rules.

Wild Stack Frenzy Slot RTP & Volatility

The theoretical Wild Stack Frenzy RTP of 96% is average, but it’s highly volatile. Despite the alluring 5,000x max payout, be watchful of your selected bets since the insignificant single payouts may destabilize your playing balance.

The Final Thoughts

If you’ve been a frequent player of online slots, you’ve most certainly gone into caves for mining activities. But to take players for speleology was such an innovative thought from Yggdrasil Gaming!

And with that came some spellbinding entertainment from appealing features.

Agreeably, the free spins are an everyday sighting in the online slot world. But the slot’s main attraction has to be the Wild Stacks, which can cover up to 6 and 10 positions in the base and bonus games, respectively. Besides giving you an extra winning boost, the stacks come with growing multipliers!

And just as I’ve mentioned somewhere in this Wild Stack Frenzy slot review, the best part for me had to be the graphical animations when symbols are destroyed from the screen.

Yes, the gameplay may be appealing. But don’t forget that it bears high volatility, which can impose a significant risk on your bankroll if you’re not careful.
