                        Inside of the High Stone Building: Castle of Terror Overview

                        Nature is beautiful, but there’s also an untamed side to it. That’s exactly how vampire creatures came to be. And that’s also what you’ll find if you look into the depths of this game.

                        At first sight, the background of this slot seems like it was borrowed from a fairy tale. The gorgeous meadows and the entrance to a silver gothic castle is really a Narnia-like scene.

                        But as soon as you start playing, holy water can change the whole setting and the meek symbols into a creepy place full of vampires. The synthesiser sounds also make the gameplay spooky.

                        The Castle of Terror gameplay is smooth and features several special symbols. For instance, some scatters can trigger free spin rounds. Both rounds feature a multiplier option set at different levels.

                        If you hit a “big win”, which is x100 your bet or greater, you can exchange the won coins for 12 free spins. Additionally, for wins that range from x25 to x100 your stake amount, you can take your potential winnings or spin the wheel and be in for a chance of getting free spins.

                        Vampires’ Heaven: Castle of Terror Gameplay

                        The Castle of Terror Big Time Gaming is a high-quality game with nice graphics. Firstly, the reel spinning motion is top-notch. The speed they land is somewhere between too slow and too fast.

                        Hitting a win also comes with interesting animations. The symbols change their colour, and the potential amount you won appears on the screen. When holy water shows up, it hits the reels in the middle, and everything changes its colour and its looks.

                        On the right-hand side, you will find all the clickable buttons. The spin button is in the bottom right corner. Above the spin button, you can see the settings button and the button to activate free spins, turn the loss limits, etc. Going further, you can adjust your bet size and use the buy bonus feature.

                        You can even jump into the Castle of Terror slot demo play and test this game before playing the real funds version.

                        The Nature of Transylvania and the Horror of the Castle: Castle of Terror Graphics and Sounds

                        As mentioned, the resolution and the graphics quality has never been brought into question here. The visually appealing symbols and nice images are the main attractions of this game.

                        The animations are also pretty interesting. For example, when holy water appears, it gets splashed into the middle reels. Once this happens, the whole background changes its colour, and the symbols change their appearance.

                        For every small win, gold coins appear on the screen. The same goes for “big wins”, but the only difference is that we see a golden coin showering. One of the most peculiar animations happens during the free spin rounds.

                        Once Castle of Terror bonus triggers are activated, you move into a castle with a very dark ambient. There’s also thunder with lightning flashing everywhere.

                        The sounds of this resemble detective and horror movies. It’s kind of weird hearing these sounds and seeing the beautiful nature in the background. But once you get into the castle, everything starts to make sense.

                        From Ordinary People to Vampires: Castle of Terror Payout Table

                        At first glance, this slot features some ordinary people symbols. However, their ability to transform brings special value to them. The rest of the symbols are levelled so that there’s a great hierarchy here.

                        Castle of Terror Bonus Rounds

                        It’s obvious that this game wouldn’t be the same without bonus rounds. So, 3 regular Silver Castle Scatters symbols active 12 free spins. Every new symbol of this type brings 3 additional free spins. In these rounds, the 1x multiplier option gets activated. It goes up every time one of the vampire symbols becomes wild.

                        If at least 3 scatters appear, and one of them is a Gold Castle Megascatter, you will enter the enhanced free spins bonus rounds. Here, the win multiplier is at x2 and increases by x2 every time one of the vampire symbols turns wild.

                        You can even get a retrigger once the multiplier reaches the x20 level. If this occurs, you will get 6 additional free spins.

                        Plus, there’s a win exchange feature. It’s about hitting the win, which is at least x100 your bet. Then, you will be able to either take your potential winnings or get 12 free spins. Also, for each win between x25 and x100, your stake amount lets you play your winnings for 12 free spins.

                        Lastly, you can use the bonus buy option. With it, you can either buy 12 regular or 12 enhanced free spins. The cheapest regular free spin package is £14, while the most expensive one is £1,050. As for the enhanced free spins, the least you can pay for them is £40. Their highest price is £3,000.

                        Castle of Terror Symbols

                        This game is set in the 19th century. That being said, some of the symbols are people who lived in the castle at this time. With some regular and bonus symbols, the entire set is complete and ready to be part of the waterfall motion.
