Upgradium Slot

Upgradium slot machineThe Upgradium slot is one of those games that is a bit different from the norm- the fun begins in an icy cave, below the earth’s surface, and upgrading gems is the name of the game.

This is Playtech’s attempt to take on Starburst, and they have done a pretty decent job. Although it’s never going to take the place of that smash hit game.

We’re somewhere remote looking for rare elements: the Upgradium Slot will make a geologist out of you. It’s a slick-looking slot on the level with the Moby Dick slot– very easy on the eye.

Everyone likes an upgrade, and that’s the feature that Upgradium delivers on.

Look and Feel

The game is set in a barren icy cavern, with crystals surrounding the reels. 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 hot spot that’s the key to triggering the upgrades.

Listen out for some pretty cheesy lift music mixed with electronic bleeps to set the scene for your reel play.

This is one of those games (like the Fortunium slot) that shines on a mobile. Playtech designed it with phones in mind.

Upgradium Game Play

Upgradium is a five-reel, three-row and 25 pay line slot that might just get you back into science in a big way!

The big hitters 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 yellow crystal, and then three other gems in different shades of green. A family of three blue rocks, a pink coloured diamond and a pyramid make up the remaining symbols.

Upgradium’s Wild (five across the reels will earn you 40x your bet), is the red crystal Wild with a subtle letter “W” which substitutes for all other icons.

Upgrading Wild

If you make a winning combo involving a Wild then you’re in luck.

The icons that make up your win are all moved one grade up to boost your win.

Crystalisation Re-spins

If you can land the big orange crystal onto that hot spot on reel three, then you activate a Crystalisation Re-spin.

This gives you a free spin with a difference, as in this mode the icons on the reels upgrade (except the Wild) to make you bigger wins.

And there’s more good news. During the bonus feature, reels 2, 3 and 4 also pick up hotspots- and if you land that big orange crystal back onto the reels into one of these, you can re-trigger the bonus game. 


The Upgradium slot is a game that has win boosts on its mind which is fine by me. The game itself is pretty basic, but the upgrading concept is good and on the right day could take you on some nice runs.

Upgradium Slot FAQs

  • What is the coolest feature on Upgradium?
    I think that is the Upgrading Wild feature (hence the name). When you get a winning combo involving a wild – the symbols that make up the win will be upgraded to the next highest-paying symbol, boosting your wins. It’s a great little feature.
  • What are Crystallization Re-spins?
    When the Orange Crystal symbol lands on the hotspot in the middle of the middle reel during the base game, you get a re-spin. The Upgrading Wild feature also runs with the symbols on the reels upgrading to the next highest-paying symbol.
