Upgradium is an online slot powered by Playtech. The crystal-themed casino game features a 5×3 layout with 25 paylines. Set inside an enchanting crystal cave on an alien planet, Upgradium invites players on a mission to look for exotic, valuable gemstones that will reward you with lots of riches.

Symbols you can find on the reels of Upgradium include crystals of different shapes and colours such as yellow, red, green, orange, blue and purple. Offering several entertaining bonus features alongside some excellent visuals, it’s no surprise that Upgradium has gained its fan base in a short period of time.

How To Play

Before players go looking for crystals, the first thing to do is register and deposit at an online casino offering the slot. Once you’ve done that, you can launch Upgradium and adjust your overall bet and the number of paylines by clicking the ‘+’ and ‘-‘ buttons beside the ‘Line Bet’ and ‘Lines’ selector. When everything is all set, you can hit the spin button to start spinning the reels!

You can also turn on autoplay if you don’t want to have to keep pressing the spin button. The feature can be enabled by clicking the ‘Autoplay’ button and selecting the number of times you want the reels to spin automatically. Feeling like a high roller? Hit ‘Bet Max’ to spin the reels with the largest bet.

Special Features


In Upgradium, the red crystal with the ‘W’ acts as the Wild symbol which can substitute all other symbols. Landing three, four or five Wild symbols will give you 4, 8 or 40 times your stake, which is amazing!

Upgrading Wild

The game also features an Upgrading Wild feature which is triggered when players create a winning combination with a Wild symbol. When this happens, the winning combination will be upgraded to the next highest-paying symbol.

Crystallisation Re-spins

There’s also the Crystallisation Re-spins feature which is triggered when the Orange Crystal symbol lands in the middle of the third reel during the base game. The Upgrading Wild feature can also be used here. When this happens, players will see the reels spin again with the symbols upgrading to the next highest-paying symbol to award players with a bigger payout.

After this, new hotspots appear on the second, third and fourth reels and if the Orange Crystal symbol lands on them, the symbols upgrade once more. Players can keep getting re-spins if the Orange Crystal symbol keeps landing on hotspots.


Upgradium is a great slot game that features some excellent crystal visuals. The Upgrading Wild feature is unique to this slot game and it’s something we’ve never seen before. It makes the game much more interesting. The combination of detailed graphics, innovative, rewarding features and straightforward gameplay means the online slot is suitable for both new and regular slot players.

We highly recommend you try out Upgradium at reputable online casinos such as Mansion Casino, BGO and Bet365.
