Playtech releases in Upgradium a game with a slightly different gameplay style and theme than most from their collection. First of all, you get a theme here that almost looks like it’s from an alien world, using materials that you’d hear about from comic books. The things you see on the reels aren’t too far off from that idea, the whole thing looking like a geological survey of an alien planet.

Upgradium’s different enough if you look at its design, but it doesn’t stray too much from the pack when it comes to the way it works on the 5 reels. You have 25 active lines, and that’s the best-case scenario. You win a top prize of $10,000 if you’re really lucky, but you also encounter wild symbols which can be upgraded, along with Crystallization Respins.

Betting and Prizes

Full control is being offered to the player in Upgradium, and it starts with the number of lines that will be active, as it should be. Once you decide how many chances to win you want each round, it’s time to pick a value for the line bet. For that part, you have a setting that goes from the $0.01 minimum, to a $10 maximum. When you play this game, you get the option to spend $0.01 to $250 per spin.

You may rely on the wild symbol when it comes to big payouts that can be yours, with 1,000 coins coming from its winning combinations, worth $10,000 at most. You don’t get the best RTP though, the figure being announced at 95.07%.

Upgradium Slot Features

A lot of the game’s appeal comes from its focus on the possibility to upgrade your features as you go along. It’s in the title and in the way that everything works.

Let’s start with the W Logo, the wild obviously. The symbol is normally both capable of forming combinations and substituting for others so that they can do the same. There are no exceptions, since no other feature symbols exist in the slot. If a winning combo forms with a wild in it, then the payout will be upgraded to the next level. It’s all from the same initial win, not a new combo that is being formed.

The Hotspot is a position in which a certain type of symbol needs to land, in order for it to be of any good to you. The symbol in question is the one that offers the second-best payout of the slot, the orange crystal formation with the pink background. Have it appear in the middle of reel 3, where the hotspot is located, and you trigger a Crystallization Respin. All the symbols get upgraded to the next symbol in line, during each respin. All positions from the middle reels are turned into hotspots, so it’s easier to retrigger the feature.

Theme & Design

Upgradium sounds like it’s inspired by some yet-undiscovered material, something that could revolutionize the world. The idea of the upgrade is built into the game and in its features, though you couldn’t tell based on what you’re seeing on the reels. The images are of logos for the feature and of colored crystal formations for the rest. The lower the payout offered, the closer to a gemstone shape the symbol is. The colors vary, ranging from green to yellow, orange and then red.


If nothing else, I’d recommend you try the game out because of its unique way of doing things. Among the thousands of slot machines that are boring, finding a gem like Upgradium is a real treat.
