Castle of Terror Slot Review

Deck the halls with all things gory because we're about to enter the Castle of Terror! Big Time Gaming's latest slot is an ode to the vampire genre, and these blood-sucking creatures are ready to hypnotise and devour you! Castle of Terror feeds on the classics of the genre. Think Sir Christopher Lee's Dracula rather than Robert Pattinson's Edward Cullen, and you'll get a picture.

Theme and Graphics

As you walk through peaceful villages somewhere in Transylvania, you'll notice a mysterious castle up on the hill. Gothic in style, it looks regal and far more inviting when bathed in sunlight than the small cottages scattered in the field. It captures the imagination effectively.

The general setting of the Castle of Terror online slot is relatively peaceful and vibrant. However, keep a close eye on the servant, the gardener, the lady and the gentleman, and you might catch a glimpse of their true nature. The animation transforming basic-looking characters into grinning creatures with fangs was quite surprising and a nice touch.

Although we loved the horror theme and the general idea behind the game (especially when you hit the Free Spins bonus and find yourself in one of the castle's chambers), we can't ignore the fact that the game's design could be more contemporary. Plus, the musical score is a bit too much reliant on 1990s SNES vibes, if you know what we mean.

Castle of Terror Slot RTP and Variance

Castle of Terror has an RTP of 96.72%. Thanks to it, it ranks much higher than average online slots you can find. Big Time Gaming made Castle of Terror a volatile game in which you have to play more than a few spins to win. Still, the maximum payout of 61,720x your stake makes it worthwhile.

Free Spins and Bonuses

Castle of Terror is full of extraordinary features, so we better see what they are all about!

Free Spins and Enhanced Free Spins

There are two kinds of free spins bonuses in this slot:

• Standard Free Spins bonus, triggered with at least 3 silver castles
• Enhanced Free Spins bonus, triggered with at least one golden castle of the 3

This is the main difference between the two kinds of bonus rounds:

• During the standard Free Spins round, the win multiplier starts at x1. It increases by +1 every time a high-paying symbol transforms into Wild.
• Enhanced Free Spins start with an x2 multiplier that increases by +2 when one of the high-paying symbols turns Wild.

Holy Water

Holy Water is a feature that triggers at random and may happen on any base game spin. The holy water from a small vial is splashed on the middle 4 reels, and 2 or more high-paying symbols will become Wild, increasing the multiplier by +1.

Win Exchange

Win Exchange is yet another way to get your hands on some free spins, but you must first trigger a win of at least 100x the stake. Once you achieve such a great win, the game will offer you to keep the money or choose 12 free spins instead.

Castle of Terror Review – Our Verdict

Regarding vampires, things can only go two ways - be a hit or a total miss. Vampirism has always been an essential part of penny-dreadful literature and B-productions, and no matter how hard certain artists try, it is almost impossible to run away from the banality of it.

Enter the Castle of Terror

Big Time Gaming dodged the bullet and created a compelling game with great payout potential and features that lift it to a new level. With two kinds of spins and two Scatters, it is more dynamic and attractive than most other Halloween slots. This is one online slot that will impress fans of Immortal Romance, Baron Bloodmore And The Crimson Castle, and the like.

Is it Worth a Few Spins?

Although it could do better in terms of graphics, the gameplay Castle of Terror offers is spot on. Every new spin is a new adventure thanks to the Holy Water feature, and the fact you can try and swap your wins to win free spins and even trigger two kinds of spin games speaks for itself. We can imagine the Castle of Terror by Big Time Gaming being one of those games you'll always come back to, regardless of the freaky faces on the reels.
