Wild Stack Frenzy slot review

Digging deep beneath the earth, Wild Stack Frenzy is a video slot from super-maker Yggdrasil. Journey deep into mysterious caverns and you might just find treasure lurking there, such as free spins and stacked wilds, leading to a max total win potential of 5,000x.

What is the theme of the Wild Stack Frenzy slot?

You have to admire Yggdrasil for spotting a gap in the slots market and going with it. There may be lots of Wild West-themed slots such as Deadwood and Ancient Egyptian games such as Cleopatra Millions, but we haven’t seen any spelunking-focussed games - until now!

Spelunking, in case you don’t know, is the process of exploring caves. You might only find more caves, but you might find hidden treasures. The caves in Wild Stack Frenzy are full of hidden treasures, from long-buried dinosaur bones to precious gems and even fantastical fungi that have grown to such a size that there is not mush-room for anything else.

How to win at Wild Stack Frenzy

Wild Stack Frenzy is played on a five-reel, three-row grid. There are 20 fixed paylines running across the board from both left to right and right to left. Payouts are awarded for landing at least three matching symbols on one of the paylines. 

The game is home to a tumble mechanism, which means any winning symbols are removed from the board and replaced with fresh ones, potentially leading to another winning combination. This can be made better by a wild, which appears over a random reel on every spin and can drop down at any time. 

Top symbols

Wild Stack Frenzy’s low-paying symbols take the form of the usual playing cards; however, they have been carved into rocks. These have a top win of 1x the bet for five of a kind. The high-paying winning symbols are the dinosaur fossils and bones, which have a top payout potential of 2.5x.

Betting limits

Stakes in the Wild Stack Frenzy begin at 0.1.

Wild Stack Frenzy bonus features

Wild Stack Frenzy is home to several bonus features, most notably the stacked wilds. You will also find a generous free spins bonus

Super-stacked wilds

Wilds come super-stacked in this game. You will notice that they have a number on them that indicates a win multiplier value that will apply to any winning combinations the wild helps to form. They can behave slightly differently depending on whether you are playing in the base game or the bonus round:

• Super-stacked wilds can be three to six spaces high in the base game and three to ten spaces high in the bonus rounds. 
• Every wild stack starts with a 1x win multiplier, which increases by +1 to a maximum of 6x in the base game and 10x in the free spins round. 
• As with most slots, wilds can take the place of any other symbol to help you complete winning combinations. 

Free spins

The free spins bonus is triggered by landing three, four or five of the game’s scatter symbol, giving you 7, 9, or 11 free spins respectively. More free spins can be retriggered during this round. During the free spins, the super-stacked wilds can be longer and help you land more prizes.

Wild Stack Frenzy review summary

Wild Stack is an unusual sort of game. The theme isn’t something we have come across before, but it works pretty well and it was a great idea to add a tumble mechanism to replicate falling rocks to match the subterranean exploration focus. 

The wilds add even more to the game, and the stacked wilds are brilliant. There are also retriggering free spins to spice things up if it ever looks like it is starting to slow down.

Wild Stack Frenzy also does the basics well. The high volatility and limited payouts are offset by the tumble feature, while the graphics and overall playing experience are as good as you would expect from the maker of online slots such as Vikings Go To Hell and Orient Express.
