Quartz SiO2 by Lady Luck Games is a 5x3 slot with medium-high volatility, 5, 10 or 15 paylines, and an RTP range of 88% to 95.9%. The game follows a space-themed setting and is built around black stones, with a layout that places the main features on reels 2, 3 and 4.
The main mechanic is the Expanding Wild. When a wild lands, it spreads across the full reel and can help complete winning combinations. Each Expanding Wild can trigger a respin, during which the covered reels remain in place. If one or two more Expanding Wilds appear during the respin, another respin is awarded.
Players who want to test the slot can use the demo version to play for free and practice before playing for real money. Quartz SiO2 also includes a gamble feature, where wins can be risked on red or black for a double result, or on card suits for a four-times increase. The maximum win is listed at 900x the bet, with a minimum stake of €0.05 and a maximum of €100.
