Playtech’s crystal-themed Upgradium slot features five reels and 25 paylines. It features several fun bonus features alongside some excellent visuals.
How to Play
Before players go looking for crystals, they should adjust their bets and bet lines by clicking the ‘+/-‘ buttons. Players can also turn on autoplay if they don’t want to have to keep pressing the ‘Spin’ button.
In the game, the red crystal with a ‘W’ acts as the wild symbol which can substitute all other symbols except the scatter symbol. Landing three, four or five wild symbols will give players four, eight or 40 times their stake, which is amazing! 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.
There’s also the Crystallization Respin 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 against 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 respins if the Orange Crystal symbol keeps landing in 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 and we highly recommend you try it out.
