Castle of Terror RTP and Volatility
Theme

Walking on a sunny morning, you will find a beautiful old castle that stands alone on a hill. When you want to get closer to it and get acquainted with the local inhabitants, you will meet ordinary peaceful people, but when the full moon comes, they will turn into evil vampires. As an experienced gambler, you know that Wild Holy Water will help you in this matter. If you defeat these vampires, you will receive a very high reward.
In the ancient Castle of Terror, you will come across mystical symbols that can be exchanged for credits. For example, for card symbols are the lowest-paying ones, for a gardener, a maid, and a gentleman are the medium symbols, and an evil lady pays the highest wins. The wild symbol in the form of holy water can replace symbols and increase the multiplier for the winning spin by +1. Scatter symbols start the game with free spins, and Mega Scatter will be able to open the round with Enhanced Free Spins.
