Social casino studio Plumbee has expanded the range of games it offers on Mirrorball Slots with the launch of Quickspin’s winter-themed slot Crystal Queen.

Crystal Queen is a 5x3-reel, 20-line slot which can expand into 5x6-reel, 56-line game, and offers multiple chances to win with its swooping reels feature.

After each win a layer of ice melts away, dropping an additional row of symbols into play, with up to six rows and a win multiplier of up to 5x the stake to unlock. It also comes with a spreading wilds feature in which a special symbol adds up to 5 extra wild symbols around the triggering symbol.

Three free spins symbols also unlocks the a free spins bonus game, where all rows are unlocked and wins count in both directions to allow for even larger jackpots.

Crystal Queen becomes the latest title released by Plumbee this year after the likes of Sevens High, Mermaid’s Treasure and most recently Titan Thunder, available on Android and iOS devices.

“The team here at Plumbee have worked hard at deploying our games schedule on time and we’re delighted to announce the launch of our latest, QuickSpin developed game, Crystal Queen,” Plumbee’s slots producer Mark Claxton said. “The free spins bonus is pretty unique as it starts with all rows unlocked plus the ability to win on lines in both directions, we really think players will love this new feature.”
