Castle of Terror Slot Review

Castle of Terror is not a Megaways game. Instead, this is a spinning reel slot with 4,096 ways to win.

“W” is Wild, and these symbols substitute all symbols except the two types of scatters.

There are two types of Scatters – the regular Silver Castle Scatter, which appears on reels 1-5, and the Gold Castle Megascatter appears only on reel 6.

The other symbols are Lady, Gentleman, Maid, and Gardener, the high-paying symbols, paying 0.6x to 50x on the bet for six of a kind. The lower value symbols are 9 to Ace cards, paying 0.3 to 0.5x your stake for six.

In the base game, you need three or more scatter symbols to trigger the Free Spins.

Castle of Terror Free Spins Award

Holy Water Feature

Land some Holy Water for a bit of extra protection. With every spin, there is a chance that Holy Water will splash two or more positions on the center four reels. When this event happens, any high-paying symbol hit by Holy Water becomes Wild and increases the win multiplier for that spin by one.

Free Spins

Three of any Scatters will trigger 12 Free Spins, plus three additional spins for each Scatter beyond the third. However, one triggering Scatters must be a Megascatter to enter the Enhanced Free Spins.

The Holy Water feature happens on every Free Spin for bigger wins. The win multiplier starts at one and increases by one every time a high-paying symbol becomes Wild.

Castle of Terror Free Spins

Enhanced Free Spins

You can enter this feature when one of the triggering Scatters is a Gold Castle Megascatter. The Holy Water feature emerges on every Free Spin. Bigger wins can be hit in the Enhanced Free Spins, where the win multiplier starts at two and increases by two each time. Every time the win multiplier reaches a multiple of 20, you hit the blood bank and receive an additional 6 Free Spins.

Castle of Terror Holly Water Feature

Win Exchange Feature

It is another way of possibly starting free spins. Whenever you win between 25 and 100 times the stake, you can exchange the entire win for the chance to be awarded 12 Free Spins. The possibility of winning the gamble is shown in green on a wheel. Whenever you win 100 times a stake or more, you can exchange 100 times your stake for 12 Free Spins.

Bonus Buy

You only need to press the Bonus Buy icon to purchase 12 Free Spins for 70 times stake or 12 Enhanced Free Spins for 200 times stake!

The result of the Castle of Terror review

Castle of Terror is a very high-volatility slot game. RTP is 96.72%

In our opinion, this time, Big Time Gaming has managed to create an intriguing and exciting online slot game with a theme we didn’t expect from BTG, knowing their portfolio. The graphics of Castle of Terror are fantastic and extraordinarily detailed. Mainly the backdrop looks like a painting. It depicts a fall scene of a picturesque landscape with a cemetery in the foreground and the Castle of Terror on a hill.

On the gaming side, the Holly Water and the progressive multiplier that doesn’t reset between spins make up for the lack of Megaways, considering excitement and intrigue. In addition, the game’s potential is impressive, 61,720 times your stake. So, as we said before, Big Time Gaming created another exciting online slot game worth your attention visually and gaming-wise.
