Quartz SiO2 Theme
As common as quartz is on the Earth, players will enjoy a unique gaming experience with Quartz SiO2, further enhanced by the superior audio background composed by Andrew Vasilyev. The game is set on the outskirts of the universe, where only the bravest of all players dare to go. As dark and gloomy as the background is, it is also very compelling.
The 5×3 playing grid is transparent, providing a view of the mysterious dark space behind it. The game visuals include four mysterious stones, hiding glowing gems beneath their black surface, as well as four playing card suits. Lady Luck Games has done a wonderful job of combining the themes of space and gems to produce an engrossing gaming experience.
How Quartz SiO2 Compares to Other Slot Games
Playtech’s Space Digger is very similar to Lady Luck Games’ Quartz SIO2 in terms of theme and symbols. Both games offer an intergalactic adventure with the promise to uncover precious gems and big rewards. As far as game metrics are concerned, however, there are some differences. Space Digger makes use of 20 fixed paylines and bets vary from 0.10 to 500.00. The game is equipped with Stacked Wilds that move one reel to the left until casino enthusiasts land a win. Additionally, the game comes with a proprietary Game Modifier Feature, enabling customized play for selected players.

Quartz SiO2 Symbols and Payouts
With the themes of space and precious stones set at the centre of attention, the slot symbols include 8 regulars and a Wild. Players can choose to activate either 5 or 10 paylines. The slot’s symbols pay both ways – this gives players the chance to land wins from left to right and from right to left across their paylines.
The four high-value symbols are depicted as dark stones, with a hint of a mysteriously glowing material beneath the surface. When players score a win through any of these four stones, their dark shell is shattered and a glowing precious stone gets revealed in the process. Landing five matches of the red, green, blue, and yellow stones generates returns of 250x, 120x, 60x, and 50x the line bet.
The low-value payouts come from four card suites. The top prizes that diamonds can generate for five-of-a-kind combinations amount to 40x the line bet. Hearts, spades and clubs produce payouts of 25x the line bet as long as players align five copies on a payline.

Bonus Features Overview
Quartz SIO2 includes a multitasking Wild symbol, which acts as a substitute for the rest of the symbols from the paytable. It also expands to cover the whole reel and triggers a special feature. Furthermore, players can pick between collecting their wins or taking advantage of the optional Gamble feature.
Wilds and Scatters
As mentioned above, the Wild symbol in Quartz SiO2 performs several important functions. Firstly, it substitutes for all other symbols from the game, thus enhancing players’ chances of landing more winning combinations. Secondly, once the Wild lands on any of the inner reels, it expands and covers the whole reel. This produces more winning combinations, along with the added advantage of triggering a Respin for free.
Respin
While the Respin feature is on, the Wild remains sticky. Once players land one or two extra Expanding Wilds after the Respin, a second Respin will be generated.
Gamble Feature
When players score a win that does not exceed 100x the stake, they can take advantage of the optional Gamble feature. It is present in many slots produced by Lady Luck Games and enables casino enthusiasts to double or quadruple their wins or lose them. To double their original bet, players must pick a card colour, with a 50% chance to win. To quadruple their original bet, they must pick a card suit, with a 25% chance to win.
