Review of Dark Vortex

With this release being in October of 2018, it is perfectly suiting to the current month as everyone is mostly feeling in the Halloween spirit. Yggdrasil released another Halloween themed slot game called Wolf Hunters just a few weeks ago, and now Dark Vortex has its time to shine with its dark, dreary and spooky theme.

The aim of the game is to open a spooky portal which leads to the netherworld entering a land filled with some fantastic wins. Players will be able to open an ancient vortex containing taller reels leading to high pays and stacked wilds! Yes there are a lot of very cool features in this Yggdrasil slot game and we can’t wait to fully get into them with you.

How to Play Dark Vortex on UK Casinos

Upon entering the Dark Vortex slot game you notice a scary looking backdrop and an intro that will make the hairs stand up on your arms. This is a game for those looking for a little spookiness with the chance of earning some great wins, but before you get too carried away in this eerie world it would be wise to adjust your betting limits to what you feel appropriate.

The minimum amount in which you can bet is £0.10, and the maximum amount you can bet is £50. You can alter your bet amount by using the Coin Value tab at the bottom of the screen, once this is complete you are free to begin spinning in this vortex surrounded world on any of your most loved casino sites in the UK!

Vortex Reels

The main symbol in the Dark Vortex slot game is of course the Vortex symbol. This is represented by...yes, you guessed it, a Vortex. By landing with two of the Vortex symbols on adjacent reels will convert them into Vortex Reels which will last for 3 spins. Each additional adjacent Vortex Symbol on your reels will award you with an extra Vortex reel and two extra spins on top of that.

If you change the coin value whilst a Vortex reel is open, it will close all Vortex reels and reset any Free Spins you have gained in the portals. Another thing good to note about Vortex reels is that it is possible to open Vortex reels on reels 1 and 2, along with a separate set of Vortex reels on reels 4 and 5. When this part of the feature happens 3 Vortex Spins will be rewarded to you for opening the first Vortex, and 4 Vortex Spins for the second. The way in which this feature ends is if all of the Vortex Spins have been bet without expanding to all 4 reels, your Vortex reels will be reverted back to the base game reels.

Orb Collection

There are a collection of Orb symbols in the Dark Vortex slot game and they are only able to appear on Vortex reels. Once you have managed to open the Vortex, 2 beautifully bright Pink Orbs, and 5 Blue Orbs will be added to your collection. These collections will collect up until the Vortex reels have closed and then it will be reset. The pink orbs and the blue orbs each have a different purpose in the game, the Pink Orbs will add 1 Wild to the Stacked Wilds on the 3 center reels in Vortex Free Spins. Pink Orbs are only able to land on reels 1 and 5. The Blue Orbs will add 1 extra Free Spin during Vortex Free Spins, and Blue Orbs can only land on reels 2, 3 and 4.

Dark Vortex Free Spins

The Dark Vortex Free Spins have got to be everyone’s favourite feature in this slot game. By opening all 5 Vortex Reels before running out of the Vortex Spins will award you with Vortex Free Spins! One Free Spin will be rewarded to you for each Blue Orb you have collected, and the best part of all is that Vortex Free Spins have 5x5 reels and a whopping 3125 ways to win. During Free Spins, the center 3 reels will all have Stacked Wilds, and the stack is increased by 1 Wild for every Pink Orb added to the collection.

During Free Spins, the center 3 reels will all have Stacked Wilds

Buy Bonus Feature

The Buy Bonus feature is probably the most exciting part of the Dark Vortex slot game because not only is it a Bonus game, but it is also a Pick and Click feature, good job Yggdrasil Gaming, we love a good Pick and Click feature! This is where players will be able to pay 80x their bet to activate Vortex Free Spins with 5-20 Free Spins and 2-10 tall Wild stacks depending on the cards you end up choosing in the pick and click feature.

During the first Pick and Click feature you will need to choose 1 of a selection of 5 cards on your screen which will decide exactly how tall the Wild Stacks are. During the second Pick and Click feature you will choose 1 of 5 cards again but these will decide how many Free Spins you will be awarded. Keep in mind that this feature is only available when there are no Vortex reels open.
