Quartz SiO2 comes to us from Lady Luck Games, finished with a clean, modern look. It runs on a 5-reel grid running 10 paylines with high volatility, and 95.57% RTP.
The mechanics are what make Quartz SiO2 interesting. Look out for scatter symbols that unlock free spins and extra bonus rounds. With high variance, this one is aimed at players who can ride out the swings for the top wins. All told, it's a solid entry in the Lady Luck Games catalogue.
At 95.57%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
High volatility means longer gaps between wins, but when wins do land, they can be significantly larger. A bigger bankroll and patience are recommended for this type of slot.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Quartz SiO2 features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
