Gold Mine Mistress

Gold Mine Mistress by Red Tiger is a video slot played on a 5×3 reel grid with 20 fixed paylines. The game is set in an underground gold mine with a Mistress character overseeing dwarves mining gems and gold nuggets in dark caverns. There is a “Work Shift” feature that works in cycles of eight spins: during spins 1 through 7 you collect Golden Nugget symbols on the third reel, which determine a bonus effect on the eighth spin. On the eighth spin respins occur if no winning combination appears, continuing until at least one win results, and any Golden Nuggets collected trigger a Mistress Wild on that spin. The Mistress Wild can appear as a 1×1 wild with a 2× multiplier, a 1×2 wild with a 5× multiplier, or a 1×3 wild with a 50× multiplier depending on the number of Nuggets gathered. Free Spins are awarded if an Apple scatter lands on reel 5 during the eighth Work Shift spin; this activates a Free Spins round. In free spins the Apple scatter becomes a moving marker that shifts one reel position each spin, and the Mistress Wild may appear on any of the middle three reels. Multiple Mistress Wilds can land in free spins and if more than one appears on a winning line their multipliers multiply together. There is no option to buy the bonus round.
