• Holy Water Feature:
  • Holy Water is randomly splashed on 2 or more positions on the middle reels during base game spins. If it hits a vampire character, that symbol turns into a wild and boosts the win multiplier by +1 for that spin.
• Free Spins and Enhanced Free Spins:
  • Triggered by landing 3 or more Silver Castle Scatters, awarding 12 free spins. Additional scatters add 3 more spins each. Holy Water is activated on every spin during the Free Spins round, and the win multiplier persists and grows with every wild transformation. If you trigger the round with a Gold Castle Scatter, you unlock the Enhanced Free Spins, where the multiplier starts at 2x and increases by +2 for each wild conversion.
• Win Exchange Feature:
  • If you score a win of 100x your bet or more, you can exchange it for 12 free spins. Alternatively, for wins between 25x and 100x, you can gamble your winnings on a wheel for a chance to trigger free spins.
• Bonus Buy:
  • For players outside the UK, you can buy your way into the free spins round. The regular free spins cost 70x your bet, while Enhanced Free Spins cost 200x.
