General overview 

Upgradium, a Playtech slot, that is surely a little masterpiece on its own. If we are to tell one thing about this slot that would be that is marvelously different! Slot itself features 5 reels and 25 paylines and great coin value size, so, it can be played as little as 25p up to very high amount of 250£. This particular slot is something every true slot lover must try at least once. 

 

Design 

The game design is something to talk about, that’s for sure. Game is set in cave-like ambient where beautiful attractive colors with most amazing color spills we have ever witnessed. The symbols come in form of various crystals with each and one of them have a unique little animation and glow. And yeah, they do come with perfect sound effects and background music. Full house! 

 

Wild Symbol Feature 

The Red Crystal with ‘W’ in it is wild symbol of the game and it has two main features. 

First one is that it will substitute all other game symbols and act as a multiplier giving you 3,4,5,8 or 40 times your stake.  

The second feature wild symbol has is something called the Upgrading Wild Feature. This particular and really unique slot feature is triggered only when you make a winning combination that involves a wild symbol in it. Once you do, the symbol that was involved in winning combo will be upgraded to next highest paying symbol of the game and thus boost your payouts to the great amount. Now since, wild symbol is appearing often in this game, it is more than fair assumption that you will get this payout very frequently – and you will. 

 

Crystallization Respin Feature 

While Upgrading Wild feature is really generous and nice what this game needs is some high-paying bonus round…and it got it in form of Crystallization Respin bonus feature. During the normal spins if you get Orange Crystal symbol in the central reel you will trigger this bonus round. Once round is triggered you will notice that there are 3 hotspots in it. As long as you have at least one orange symbol in hotspot, the game will keep going and upgrading your reel symbols to the next highest paying one. We didn’t come across something like this in any other slot game apart from Starburst slot so we give this feature 10/10 stars. Like that isn’t enough, the Upgrading Wild feature can also be triggered within this bonus game! 

 

Final Words 

This hefty little slot game is truly a wonder of free casino games. With ability to get as high as 1,000 times of your stake (if you are lucky enough with wilds) this game will and is on all top lists of no deposit required online casinos
