Castle of Terror Slot Features

  • 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.

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. This feature is not available at UKGC casinos.
