We were really drawn into the atmosphere of Castle of Terror and give top marks to the production team for the sound and visuals. The classic gothic theme also makes plenty of appeal in a genre heavily populated by comic book/video games style offerings.

Aside from the theme and atmosphere, it’s hard to knock a game with an above-average RTP and huge max win potential. No doubt this is a highly volatile game, but that only serves to add to the hair-raising experience.

For those scouting online casinos for a horrific slot experience, this release from Big Time Gaming rates a fang-tastic option.

Castle of Terror Slot Review

Top developer Big Time Gaming has provided a real treat for online slots players who like their games to come with a little added bite.

Set against a serene backdrop, Castle of Terror initially has the vibe of a rather beautiful autumn painting. Blue skies, rays of sunshine, all in all, a relaxing place for a stroll.

But hold on, those characters on the reels don’t look entirely trustworthy, do they? Once the sinister synths and twinkling pianos of the driving soundtrack kick in, it quickly becomes clear that all is not well in this part of town. What could lie inside that castle on the hill? Terror, you would imagine, given the title, but it turns out that the imposing castle is in fact home to the rewarding bonus game.

Featuring transformative wild symbols, multipliers, and two bloodcurdling bonus rounds, should you escape this castle intact, you may emerge with a Max Win of a whopping 61,720x your stake!

Castle of Terror Slot How to Play

The game takes place on a standard 6×4 layout, offering a total of 4096 winning ways. The reels themselves are set into the gateway leading to the castle, but you will need to make it through to one of the bonus rounds to enter the castle itself.

10, J, Q, K, and A playing card values provide the games low-value symbols, with the residents of the creepy castle acting as the higher paying icons – namely the Gardener, Maid, Gentleman, and Lady. Of these, the Lady is the most by far the most rewarding – paying out 50x for six in a row. Wins are recorded by landing matching symbols on adjacent reels, beginning with the leftmost reel and moving to the right.

Castle of Terror on Mobile

Fans of ghoulish gaming on the go will be happy to learn that Castle of Terror is available on mobile and other small-screen devices. Whether you be an iOs or Android user, you will find all of the gameplay, features, and sinister setting intact.

Castle of Terror RTP and Volatility

Castle of Terror has an RTP of 96.72% – 0.72% over the industry average of 96%. That may not sound like much but is an excellent return for a game of this nature and high Max Win potential.

The game falls firmly into the High volatility category, meaning that, on average, players may need to ride out periods of low wins and dead spins, before reaching the potentially rich rewards of the Bonus Rounds.

Castle of Terror Slot Bonus Round and Free Spins

Holy Water Feature

The base game is livened up by the randomly triggered Holy Water Feature. The sky dims as a bottle of the blessed liquid appears on screen, before crashing onto the four central reels – leaving a random number of spots soaked in water.

Should one of the four “human” characters then land in a saturated position, they will briefly reveal their true vampiric nature, before transforming into a Wild Symbol. Not only that, but each character that turns wild will also add +1 to the winnings multiplier for that spin.

A Deadly Double of Free Spins Rounds

The Holy Water feature does provide the opportunity to land decent-sized wins in the base game, but the really fiendish fun lies in the two Free Spins Bonus Rounds.

The game features two types of Scatter Symbol; the Silver Castle Scatter which can appear on any reel, and the Golden Castle Scatter which will only show up on reel six.

Land 3,4,5, or 6 scatters anywhere on the reels to win 12, 15, 18 or 21 Standard Free Spins.

However, should a Golden Castle Symbol help to trigger the bonus, you will instead move into the Enhanced Free Spins Round.

Standard Free Spins Bonus Round

The action moves inside the castle for the Bonus Round, taking place in a ghastly gothic room, complete with crimson curtains, candles, and a general feeling of unease. The synth soundtrack becomes still more sinister, adding nicely to the level of tension.

Free Spins take place on the same reels as the base game, with the only difference being that the game’s characters are now permanently in vampire mode.

The Holy Water Feature is in play for every spin during Free Spins, triggering Wilds and Multipliers in the same manner as the base game.

During the Bonus Round, all multipliers remain in play for all remaining spins, granting the possibility of rapidly escalating wins. Should your multiplier tally reach 20x, you will be awarded 6 further free spins. This process then repeats for every multiple of 20, i.e., when the winnings multiplier hits 40x, 60x, 80x etc.

The round ends when your spins run out, setting off an unsettling wailing scream in the background before your winnings are tallied.

Enhanced Bonus Round

Good as the standard Free Spins round is, things are ramped up a notch in the Enhanced Free Spins Round triggered by the Golden Castle Scatter.

The setting is once again the haunting interior of the castle, but this time it is not only the curtains which are red – a blood-red moon also shines through the window adding a further layer of horror to the proceedings.

The enhanced round plays out in much the same way as the standard round, but the multipliers receive a serious boost. Starting at 2x, each Wild triggered by the Holy Water Feature will see +2 added to the multiplier, enhancing winnings, and greatly increasing your chances of hitting the 20x target to win six further free spins.

Make a Devilish Deal with Win Exchange

Landing scatter symbols is not the only way in which to reach the Bonus Round. Should you win 100x your stake, or more, on any spin in the base game, you will be given the option to purchase 12 Free Spins for 100x.

Win between 25x and 99x on a single spin, and you will instead be granted the opportunity to gamble for 12 Free Spins. You may keep what you have won, or risk it all on the spinning wheel.
