How to Play Quartz Sio2

At Slots Temple, whenever we get a new Lady Luck slot demo to play, the first thing we do is find out how we can control it and then go through the game’s rules. For Quartz Sio2, they are all under the reels as follows:

1. Begin by searching for the ‘?’ symbol in the lower right-hand side of the monitor, which will pop up game information with unique abilities and RTP attached to it.

2. Then, press on the ‘I’ icon which is situated at the furthest left of the control panel to access details such as paytable, paylines and bonus features.

3. First, understand the terms of trade for the slots and then place your bet by simply clicking on “+” or “-“ buttons which are located on the right side of the ‘I’ icon just next to ‘Total Bet’.

4. If you’ve got the right bet, select the biggest Spin key on the extreme right of your dashboard to roll one time. But if you want, you might use ‘Auto’ option for turning it on or off. Besides this button is “Turbo” mode’s on/off switch. This is a rewrite whose goal was to capture all ideas in the original text but in different words and stylistic variation.

5. You can constantly watch your overall balance at the bottom of the operational switchboard.

Quartz Sio2 Bonus Features

There are a few additional features to watch out for in Quartz Sio2. To make this easier for you, we’ve separated these below.

Wild Respin

In the reels you can find a wild symbol which can replace any other on the reel for better winning combinations. A wild will expand and fill all places in case it lands there, this would trigger an extra spin and the wild remains active.

Gamble Feature

Quartz Sio2 possesses a double-or-nothing feature called the gamble where you can stake your prize money of any winning combination. In this game, you have to predict if the face-down card will expose red or black color and own double your winnings or predict a correct suit on the card to quadruple your bonuses. Nevertheless, take caution for even one wrong guess could make you lose everything!


In general, we found Quartz Sio2 to be a well-designed futuristic slot machine that offered some amazing rewards as well as decent bonus features. Though for example it would have been nice to have had a round of free spins in this game, but then the Wild Respins gave us many chances to raise our earnings and the gamble feature was an added benefit. However, we were struck by the excellent graphics and soundtrack in this game that made it feel very atmospheric indeed and therefore highly immersive while playing.

There is a chance that you may like Quartz Sio2, if so, you could check out Machina Megaways Slot from Kalamba Games and Relax Gaming with more futuristic spinning potential.
