Leading online and mobile casino content provider iSoftBet, has announced the release of its latest slot game, the gothic-themed Night Queen.

The new 5 reel, 3 row and 20 pay line ‘Night Queen’ is a medium variance slot with a set RTP of 96.26 per cent that is playable from £0.20 up to £100 per spin.

A unique Switching Stacks mechanic in the slot game sees any full stack of one symbol switching with any other full stack of a different symbol helping to create wins, while three consecutive matching stacks form a colossal symbol, with a chance for a win multiplier of up to 30 X to be applied to it.

One symbol is randomly selected on every spin to become super-stacked on all 5 reels with the super-stacks being even longer in the Free Spins, leading to lucrative win potential.

The Free Spins bonus is triggered by 3 or more Night Queen symbols with added mystery symbols always landing in stacks to transform into any other random symbol.  These stacked mystery symbols can also switch with any other stacks to produce even more colossal wins.

Mark Claxton, the Head of Games at iSoftBet, commented on the new release by saying that ‘Night Queen’ combines tried and tested land-based game-play with a ghoulish, haunting theme that has been inspired by classic novels of the era.

Claxton went on to say that loaded with both stacked and mystery symbols, alongside their unique Switching Stacks mechanic and colossal multipliers, their new slot game’s compelling game-play will keep players entranced as they enter the domain of the mysterious Night Queen.
