iSoftBet introduces Night Queen
The unique Switching Stacks mechanic means any full stack of one symbol can switch with any other full stack of a different symbol to help create wins, while three consecutive matching stacks will form a colossal symbol, with a chance for a win multiplier of up to 30x to be applied to it.
Meanwhile, on every spin, one symbol will randomly be selected to become super-stacked on all five reels, while in free spins these super stacks are even longer, leading to huge win potential.
Three or more Night Queen symbols will trigger the Free Spins bonus, where added mystery symbols always land as stacks and will transform into any other random symbol. These stacked mystery symbols also have the potential to switch with any other stacks, producing even more colossal wins.
Mark Claxton, Head of Games at iSoftBet, said: "Night Queen combines tried and tested land-based gameplay with a ghoulish, haunting theme inspired by classic novels of the era.
"Loaded with both stacked and mystery symbols, alongside our unique Switching Stacks mechanic and colossal multipliers, our new slot's compelling gameplay will keep players entranced as they enter the domain of the mysterious Night Queen."
