Those of you who enjoy horror-themed online slots are going to love the Castle of Terror. As its name might have given away, this Big Time Gaming slot is based on a mysterious castle – one that comes complete with a terrifying lady and gentleman couple who, quite clearly, have a tendency for sucking blood. It’s all in the name of fun, and Big Time Gaming has loaded this up with some spooky bonus features, too. Check out the best casino bonuses and take a more detailed look at this Castle of Terror slot review.
You might be quite surprised when you load up the Castle of Terror slot to find that the base game actually takes place in a really colorful setting. The castle itself sits in the background of the slot, overlooking a small, leafy town that looks as though it has been taken straight from the hills of Central or Eastern Europe. This is accompanied by a slightly eerie soundtrack, though, one that foreshadows the darkness that you enter when you trigger one of the bonus rounds. Players then move inside the dark halls of the castle and are greeted with a much darker color palette as well as some haunting imagery. It’s all very well-designed and is definitely one of the best-looking Big Time Gaming slots.
You can get spooked by the Castle of Terror on both your desktop and mobile devices. The game has been fully optimized to work on a range of different screen sizes and operating systems and can be played at a range of top mobile slot sites. The Castle of Terror mobile slot offers the exact same gameplay mechanics and bonus features as the desktop version.
Thankfully, there is nothing terrifying about Castle of Terror. The action unfolds across a 6x4 grid. This larger grid, along with a pay ways system allows for up to 4,096 different ways to win on each spin.
The stake is displayed on the right-hand side of the grid and is adjusted by clicking on the arrows on either side of it. The minimum bet in the game is $0.20 and the maximum is $15, making for a small betting range that will suit those on more conservative budgets. The standard autoplay options are also available in the game.
The Castle of Terror springs from its slumber for its bonus features collection. Firstly, there is the Holy Water bonus.
On any random spin, the middle four reels can be splashed with Holy Water. When this happens, any of the four character symbols that are on those reels will be turned into a Wild. A win multiplier is then added by one for that spin. All wins are then evaluated after the symbols have turned Wild.
The other main feature of the slot is the Free Spins. These are launched by landing three or more of the Scatter symbols. There is both a Gold Scatter and a Silver in the game. Twelve spins are launched, with three additional spins for each Scatter past the third that triggers the round.
During the round, the Holy Water feature is active, and any multipliers that are triggered through the Wilds don’t reset between each spin. If you triggered the round with Silver Scatters, then this starts at 1x and increases by one, and if you did it with a Gold Scatter, then you get the Enhanced Free Spins, with the multiplier starting at 2x and increasing by two. Every time the multiplier reaches 20, an additional six spins are added.
There are some seriously big wins on offer in the Castle of Terror slot. The maximum amount that can be won in the game is 51,720x the player’s stake, which is a really nice number. The RTP of the game is 96.72%, which puts it comfortably above the industry average for real money slots online which is 96%. The slot is considered highly volatile.
Castle of Terror is a really strong offering from Big Time Gaming. The game has a great design and shifts seamlessly between two different settings. The bonus features, while not groundbreaking or wholly original, complement the slot really nicely and provide some big winning potential. Building up a strong multiplier in combination with the Holy Water feature can lead to some really nice opportunities during the Free Spins round. On the whole, this is a castle that is well worth exploring at one of our selected slot sites.
