Upgradium is a 5 reel, 25 payline slot from Playtech that can be played on all devices from 25p to £250 per spin. With a futuristic, crystals feel, it benefits from an Upgrading Wild feature where the symbols that are part of the winning combination. It also comes with a Crystallization Respin feature where you get a free respin with all symbols upgrading for enhanced wins.

Visually, Upgradium is set in a gem-filled cave which looks like it’s the place where Superman gets his kryptonite! With a futuristic feel to it, symbols on the reels include a variety of 3D shapes and crystals. The Red Crystal W is the wild symbol and replaces all symbols to give you the best possible combination – it’s also the most lucrative with 3, 4 or 5 giving you 4, 8 or 40 times your stake.

Upgradium comes with an Upgrading Wild feature which is played when you get a winning combination involving the wild – when this happens, the symbols involved in the win will be upgraded to the next highest-paying symbol. This will basically give you enhanced wins.

Now, the Upgrading Wild feature also applies in the Crystallization Respin feature which is played when the Orange Crystal symbol lands on the hotspot in the middle of the central reel (reel 3) during the base game. You will then see the reels spin again with the symbols on the reels upgrading to the next highest-paying symbol (bar the wild as it’s the most lucrative).

New hotspots appear on reels 2, 3 and 4 with those symbols upgraded for bigger wins. If you get a wild, those symbols upgrade again. You can continue to get respins as long as Orange Crystal symbols appear in hotspots or there are no hotspots left.

Basically, Upgradium is a simple slot that looks quite a bit like NetEnt’s Starburst – it’s all about upgrading symbols for enhanced wins. Variance wise, it’s in the middle with maximum wins of 1,000 times your stake if you manage to fill the reels with wilds. I recommend you try some of Playtech’s more volatile offerings like Dragon Champions which offer more in the way of bonus features.
