At first glance, the Castle of Terror slot seems to invite you into a fairy-tale world, with a beautiful castle set in glorious scenery.

Castle of Terror Slot Features

Like many of the best new slot games, this game comes chock-a-block with features. Though there is one surprise: the wild symbols are part of a larger feature, rather than a symbol that lands on its own! Let’s explore them.

  • Holy Water: Triggered at random, this feature will see at least two positions on the centre four reels get a splash of holy water. This instantly turns any of the vampire characters into wilds with a win multiplier that adds a 1x to the general win multiplier at the top of the grid. At the end of the spin, your total win is multiplied by the value shown at the top before it gets reset.
  • Free Spins: Landing three Silver scatters will award you 12 free spins, with any additional scatter symbols being worth an extra three spins each. During this feature, the Holy Water feature is constantly active and doesn't until the end of the feature.
  • Enhanced Free Spins: Landing at lead one Gold Mega Scatter – which appears on Reel 6 only – will activate the Enhanced Free Spins. During these spins, the Holy Water feature is active, turning character symbols in wilds with a win multiplier that doubles each time (2x). Moreover, you’ll be awarded an additional six free spins if the win multiplier reaches 20x.
  • Bonus Buy: If you don’t want to wait for the free spins feature to drop, you can pay 70x- or 200x-your-bet-per-spin to buy into the 12 Free Spins or the 12 Enhanced Free Spins feature, respectively.
