Would you like to enter into the world of fossils and biological wonders? If you were going to embark upon a journey like this, it would be preferable that you’d be doing so in an open space – we’ve all seen the horrors of what can happen when people get trapped in these claustrophobic conditions.
There’s no open air for us today though, as Yggdrasil Gaming invite us to go spelunking – which is the official term for exploring caves, if you didn’t know – into a cave full of the aforementioned fossils and hidden riches. Avalanches are intended to occur here, as Yggdrasil Gaming enable players to enjoy chain wins through Wilds waiting to drop at every spin, in Wild Stack Frenzy.
With RTP options available up to 96.0%, this highly volatile release can produce wins up to 5,000x bet.
No visual surprises today as we do indeed find ourselves inside a cave. It won’t take long for our explorers to stumble across magnificent fossils or riches, as diamonds, bones and skulls line the walls – belonging to creatures much bigger than us. As far as cave imagery goes, this one looks more friendly and lighthearted than most (here’s looking at you, Dead Canary).
Aside from the fairly attractive background, players can an immediate look at the Wild Stacks that await them upon loading this one up, with increasing multipliers as we move up the reels. All in all, a pretty picture – finished off with an upbeat and slightly foreboding tune to tie it all together.
Wild Stack Frenzy Base Features
Taking place across 5 reels, wins are formed on Wild Stack Frenzy by matching at least 3 symbols on adjacent reels, across 1 of 20 fixed win lines beginning with the leftmost or rightmost reel – as wins pay both ways. Symbols available begin with non premiums, with four rocks with icons etched upon them. Land between 3 and 5 of a kind of any non premium to see wins between 0.20 and 0.50x bet.
At the premium end, we find four fossils that match in colour to their non premium counterpart. Land 3 of a kind of any premium to see wins between 0.30 and 0.50x bet, increasing to values between 1 and 2.50x bet for 5 of a kind matches. Finally, Wild symbols are available and substitute for all symbols except Free Spins symbols, but we’ll get to those soon.
Alright, the first thing to cover in Wild Stack Frenzy is the cascade feature. On every spin, all symbols involved in a winning combination will be removed from the reels, with all remaining symbols dropping down to the bottommost available position on their respective reels.
New symbols will then drop in from above to fill the remaining gaps, with cascades continuing until no new wins are formed.
Working hand in hand with cascades are the star of the show – Wild Stacks. Wild Stacks can be from 3 to 6 segments tall in the base game. For each new segment, the multiplier of the Wild symbol in that segment increases by +x1. These multipliers are then applied to all wins that pass through the respective Wild symbol.
A Wild Stack is always present above one reel, waiting to drop in during cascades.
Wild Stack Frenzy Bonus
Land 3 or more Free Spins symbols to trigger Free Spins.
- 3 Free Spins symbols – 7 Free Spins
- 4 Free Spins symbols – 9 Free Spins
- 5 Free Spins symbols – 11 Free Spins
Everything continues as normal during Free Spins, with one notable exception – Wild Stacks will now be between 3 and 10 segments tall, meaning their multipliers can now climb as high as x10.
Land 3, 4 or 5 Free Spins symbols during Free Spins to trigger an additional +7, 9 or 11 spins respectively.
Players in appropriate regions can take advantage of the Buy Bonus option, wherein for a cost of 60x bet, they can buy 7 Free Spins. RTP remains the same when buying the bonus.
The maximum win available in Wild Stack Frenzy is 5,000x bet. If the sum of a single game round exceeds this, the game round will end and 5,000x bet will be awarded.
There’s nothing particularly groundbreaking about Wild Stack Frenzy, but it does incorporate some player favourites in interesting ways – both from Yggdrasil Gaming and from the wider market. There are elements of Raptor DoubleMax in here with Wilds falling in and increasing multipliers (although not to the same extent), and the usual stacked wilds that players love to see.
In both the base game and Free Spins Wild Stacks working with cascades carry the bulk of the weight to help things feel exciting, however in Free Spins these can be up to 10 segments tall, creating multipliers up to x10 if you can continue to cascade and move stacks downward. When the right combinations occur, wins are possible up to 5,000x bet.
Finally, maths is highly volatile and RTP options are available up to 96.0%, so as always it’s worth checking this. If you’re a fan of stacked Wilds and both way wins, Wild Stack Frenzy could be a good option for you.
