Quartz Sio2 takes you on a mining mission in deep space to collect lucrative space rocks that can be used to create minerals and precious gems back home on Earth. The game is played over five reels, three rows, and 10 paylines and offers some impressive top prizes of up to 250x your wager.

To win in Quartz Sio2, all you need to do is line up three or more matching symbols along a payline. Wins are paid either way in Quartz Sio2, so as long as you land matching symbols along one of the 10 paylines in adjacent reels running left to right or right to left, you can take home some awesome rewards.

Quartz Sio2 also features a Wild symbol, which can substitute for all symbols on the reels to help you land more frequent and larger winning combinations. In addition to acting as a substitution, the Wild will also Expand to fill the entire reel it lands on and trigger a Respin to further increase your winning chances.

Quartz Sio2 also incorporates a double-or-nothing Gamble Feature to give you the chance to win even more on every spin!

We’ll look at the bonus features for Quartz Sio2 in more detail later in this slot review.

Theme, Graphics & Soundtrack

Quartz Sio2 is a beautifully designed futuristic slot set in deep space and filled with dark symbols with just a hint of colour running through them. This eerie and midnight appearance of the slot does a great job of pulling you into the game and suits the Sci-Fi theme brilliantly.

The soundtrack also adds to the atmospheric sensation of this slot, with a dark and spacey tune playing throughout the game.

Quartz Sio2 Bonus Features

There are a few bonus features to look out for in Quartz Sio2. To make this easier for you, we’ve broken these up below.

Wild Respin

The Wild symbol can substitute for all others on the reels to help you land bigger and better winning combinations. Whenever a Wild lands, it will expand to fill all positions on the reel and will trigger a respin with the expanded Wild remaining sticky on the reel.

Gamble Feature

With any winning combination, you’ll be given the chance to gamble your winnings in the Quartz Sio2 double-or-nothing gamble feature. In this game, all you need to do is accurately guess whether the face-down card will reveal a red or black colour to double your winnings, or accurately guess the suit of the card to quadruple your prizes. Be wary, however, as one incorrect guess could see you losing the lot!


Overall, we thought Quartz Sio2 was a brilliantly designed futuristic slot with some impressive prizes and decent bonus features. We might have liked to have seen a free spins bonus round in this slot, but the Wild Respins did give us plenty of opportunity to increase our winnings, and the gamble feature was a rewarding extra. We were particularly impressed with the graphics and soundtrack in this slot producing an incredibly atmospheric and immersive gaming experience.
