Upgradium slot machineUpgradium is one of those rare slots where you wonder if the world has just been turned upside down- it’s a novel game where the fun begins in an icy cave, below the earth’s surface, or maybe on an alien planet- who knows! We’re somewhere remote and looking for rare elements, Playtech’s newly thought up “Upgradium Slot” will not only make a lot of ore-lovers happy but gives you slot lovers a chance of uncovering some tasty wins- listen up! This is a slick looking slot on the level with the Moby Dick slot– let’s just say it’s very easy on the eye.

No one can say ‘no’ to an upgrade; and “Upgradium” is just the game for those who like to have a little of what you fancy with a game that is centred on boosting your winning chances.

Look and feel

We find ourselves in a barren icy cavern, with crystals surrounding the reels and entombing us in a frosty spot – but don’t worry; the reels are here to keep us busy! In a dark blue metal frame some scientific endeavour is underway! The colours remind us a lot of Berryburst and Starburst- those 2 NetEnt mega slots.

In the middle of the third reel you’ll notice a purple frame, this shows you where there’s a spot of special scientific interest – a hot spot that’s key to triggering the bonus game.

Watch out for some pretty cheesy lift music with some uplifting sounds and electronic bleeps to accompany your reel spin! This is one of those games (like the Fortunium slot) that really shines on a mobile. It’s obvious they have designed it with phones in mind.


Upgradium is a 5 reel, 3 row and 25 pay line slot to inspire your inner scientist!

Unsurprisingly the big hitters and their friends on the reels are a set of icons that come straight out of a geology manual. First is an orange spiky crystal on a pink background, a similar yellow crystal, and then a series of three rather similar crystals in differing shades of green. There are also a family of three blue rocks which go from spiky to a square shape and finally a pinky coloured diamond and pyramid!

Upgradium’s Wild which with 5 across the reels earn you a stunning x40 your bet, is a red crystal Wild with a subtle letter “W” (!) and this mighty beast of an icon substitutes for all other icons.

Upgrading Wild

If you make a winning combo involving the game’s Wild then you’re in luck. Now the icons that make up your win are all moved one grade up the values to basically upgrade your win- now that’s worth getting all scientific over!

Crystalisation Re-spin

If you can land that massive orange crystal onto that special hot spot on reel three, then you activate the free spinning action that is the wordy Crystalisation Re-spin. This activation gives you a free spin with a difference, in this mode, the icons on the reels upgrade themselves (with the exception of the Wild) to make you bigger bucks, now that is actually the kind of “Upgradium” I’m after!

And there’s more, or should I say “ore” good news. During the bonus feature with reels 2, 3 and 4 turning into further hotspots- and this is a generous game, if you lure that big orange crystal back into the reels then you can even re-trigger the bonus game. Now that’s making winning crystal clear!


Upgradium is a slot game with boosting your win on its mind which can only be welcome, but the game itself is pretty basic and I have to admit it didn’t do much to float my boat. The upgrading concept is a good one and on the right day could make you some serious dosh.
