Crystal Miners

Crystal Miners by Apollo Play is a video slot with 5 reels and 4 rows, based on 40 fixed paylines. The theme takes players into a mining environment filled with glowing crystals and quirky lava creatures digging for treasures deep underground. Wild symbols are present and substitute for other symbols (except the bonus symbol) to complete winning combinations. The bonus symbols (scatters) trigger a free spins round: landing 3, 4, or 5 bonus symbols awards 5, 10, or 15 free spins. During the free spins, additional random wilds are frequently added to the reels to increase winning chances. There is a mining modifier: occasionally, lava floods reels 2-4, and small miners shift or extract symbols into new positions that can form winning combinations. A colossal respin feature is activated when four identical high-paying symbols land on a single reel, transforming them into a large symbol and respinning the other reels. After each winning spin, the gamble feature is offered, providing the opportunity to double a win by guessing the color of a face-down card. There is no bonus buy option in this game.
