Wild Stack Frenzy

Wild Stack Frenzy: Slot Overview

If you've played a fair share of slots, there's a good chance some of them will have taken you beneath the earth's surface to break rocks while searching for precious minerals or metals via the plethora of mining games available. Ever been spelunking on the reels, though? Well, you're about to, courtesy of Yggdrasil Gaming and its slot Wild Stack Frenzy. Spelunking, if you need a translation (we did), is the activity of exploring caves, and keen spelunkers would have a field day exploring the world of Wild Stack Frenzy. Down here are caves of a lifetime filled with all sorts of wondrous eye candy, as well as wild Super Stacks with multipliers, avalanching dropdown wins, free spins, and a bonus buy.

Back to Wild Stack Frenzy's game world, and it is quite a visual feast. Down in these caverns, explorers will discover all manner of crystals embedded in the walls, masses of huge dinosaur bones, as well as monstrously sized mushrooms. There's a slight Raptor DoubleMax touch to the place, from the prehistoric references and some of the fonts, plus the rhythmical tunes give Wild Stack Frenzy a primal yet mystical feel. Other sound effects weren't built in at the time of the review, so that's something to look forward to when Wild Stack Frenzy goes live, as are two 'graphical improvements that no one expects'. Since the visuals aren't half bad already, it'll be interesting to see what they might be.

Wild Stack Frenzy plays out on a 5-reel, 3-row gaming panel with 20 paylines that pay both ways – left to right and right to left. Winning combinations may start from the leftmost or the rightmost side of the grid. With a hit frequency of 35% backed up by a cascading dropdown win mechanic, the math model is highly volatile and has a default RTP of 96%. However, just to be aware, lower return models have been designed, as well. To get spelunking, players pick a stake of 10 p/c to $/€200, and free spins can be bought for a cost of 60 times the bet.

The game's low-pay symbols have a faintly esoteric quality about them, being card suits – clubs, spades, diamonds, and hearts imprinted on rocks, which are followed by the higher-paying shell, rib bones, claws, and jaws. A winning line of 5 low pay symbols is worth 1 times the bet, whereas a 5 OAK premium win gets you 2 to 5 times the bet.

Wild Stack Frenzy: Slot Features

Since line wins aren't worth masses of dosh on their own, you're probably going to want to combine them with Wild Stack Frenzy's features, which include avalanches, Super Stacked wilds, and free spins.

Avalanche

Whenever a player lands a win, the payout is collected, then the winning symbols explode from the reels. This makes space for symbols to drop down, creating another chance to win on the same spin. Avalanches continue like this until no new combination is made, then the total win is paid out. Wild stacks are always present above a random reel, ready to cascade in after a win (on the initial spin, it seems).

Wilds

The wilds in Wild Stack Frenzy are a bit special because they are Super Stacked on their reels and appear with a number on them. The number indicates a multiplier which is applied to any win the wild is part of. The length of Super Stacked wilds in the base game is 3-6, increasing to 3-10 in free spins. Each wild stack starts with an x1 multiplier and goes up by +1 to x6 in the base game or x10 in free spins. Wilds substitute for all regular pay symbols.

Free Spins

Landing 3, 4, or 5 scatter symbols in the base game awards 7, 9, or 11 free spins. Within free spins, the feature can be retriggered. As mentioned, what changes in free spins is the Super Stacked wilds are longer than in the base game.

Wild Stack Frenzy: Slot Verdict

Got to say Wild Stack Frenzy delivered a satisfying stack of entertainment when all was said and done. It's not the sort of slot Yggdrasil Gaming likely cooked up in the bowls of its workshop to revolutionise the industry. Instead, Wild Stack Frenzy puts its head down, gets to work, and sets in motion a nice set of features within a wondrously cavernous region full of bones, crystals, and massive, maybe magic, mushrooms.

What works well is that you get a good chonk of avalanche action going on, meaning decent runs of repeat runs on a single spin or free spin may be possible. The graphical animations while Wild Stack Frenzy is smashing symbols and dropping in new ones are satisfying, alluring players with its rich graphics and immersive soundscape.Wild Stack Frenzy is undoubtedly an attractive game. The avalanching is where the Super Stacks of wilds come into play, as well; better not forget them since their multipliers are instrumental in increasing regular line wins. Stacks aren't guaranteed to reach their full 6 high in the base game or 10 high in free spins, though. Sometimes, if memory serves, a new stack of 3 may appear on top of a stack of 3 wilds already in view, meaning a new multiplier trail starts rather than continuing one. Ah, well, such is slots.

Super Stacks of wilds are there to help Wild Stack Frenzy push out winning potential of 5,000 times the bet, which, like the rest of the game as a whole, isn't amazing perhaps, but is solid, sturdy, totally respectable, and spelunking makes a nice change from just mining while underground for a change.
