Upgradium – An Uninspiring Slot Game from Playtech
Jun 29, 2018
Glowing crystalsSome of the most beautiful objects naturally occurring in nature are crystals composed of lattices perfectly arranged with beautiful results. With this in mind, the reels are at the forefront of a glowing cave shimmering in shades of blue and green. The dark reels house no less than ten non-feature symbols composed of an assortment of crystals: colour, geometric shape and size. The graphics are relatively simple, compared to some other slots, but serve their purpose. There is a musical tune which occupies the background of the slot which is frequently overlaid with the sound of audio effects culminating from the creation of a winning payline or triggered feature.
Upgrading wildThe upgrading wild can substitute for all of the other symbols when appearing on any of the reels. In the formation of part of a winning payline, the combination upgrades which in game terms means they level up.
Crystallization RespinWhen the star-shaped crystal called Upgradium arises on the centre space of the third reel, referred to as a Hot Spot, the Crystallization Respin feature is triggered where all the symbols upgrade to the next highest value in the paytable. All of the spaces in the third, fourth and fifth reels become Hot Spots for a free respin which you can retrigger if another Upgradium symbol lands within the Hot Spots.
Simple slot with popular crystal themeUpgradium slot has been designed to be played from your pc as well as tablet/mobile provided you are using Android, iOS or Windows Phone. The 5-reel slot is played with anywhere from 1 to 25 variable play lines, and we suggest you use all of them for the best chance at wins. The RTP is a tiny bit towards the lower end of what the developer usually offers at 95.07%. The variance is middle of the road so you may find wins of any sizable amount difficult to trigger, but there is a chance of larger prizes when you do. While the game doesn’t break any new ground when it comes to graphics or features, in fact, there are only two, the simplicity the game along with the popularity of crystal themes may appeal to many players.
