Castle of Terror Slot Review

By : Category : Casino Slots

Castle of Terror is an acceptable name for this slot even though, based on the backdrop image, it could appear to be a castle from a fairy tale. There are times when this castle changes, but you have to play the newest game from Big Time Gaming to get there.

Castle of Terror provides a total of 6 reels. One of the key features of the slot machine is free spins with infinite multipliers and wilds.

Betting and Prizes

With this slot machine, you can choose the bet that initiates the subsequent round, and your options are between $0.20 and $8. The Terror can be played on any device with a bet range of 20 percent to 15 pounds or euros each spin. The math model is very unstable, as we have come to expect from BTG, and the return to player fluctuates very slightly from 96.72% overall to 96.73% when purchasing a bonus.

Due to the grid’s design, it might come as a surprise, but Castle of Terror is not a Megaways game. Instead, there are 4,096 chances to win when playing on a 6-reel, 4-row panel. When matching symbols land on neighboring reels starting from the leftmost one, wins are generated.

Features of Castle of Terror Slot

The W wild is going to be one of Castle of Terror’s helpful features. Since this is a regular replacement sign, it will eventually assist you in obtaining more wins.

Additionally, you receive free spins, a bonus that offers an endless win multiplier. The multiplier will increase when wilds appear, and there is no upper limit to how high it may go. Each round in this mode also has the Holy Water modifier in effect.

Holy Water is a randomly triggered feature that splashes liquid on the middle four reels on any base game spin. When activated, the Gardener, Maid, Gentleman, or Lady appear in 2 or more locations and become wild symbols. The win multiplier for that spin is increased by one for each symbol that turns into a wild symbol. After the wild transformation, wins are assessed, and the multiplier resets for the following base game spin.

Theme & Design

During the day, it appears to be a fairly typical fairy tale castle, as shown in the background picture. With slaves and nobles used as premium symbols, the characters displayed on the reels also appear typical for such a setting. The lowest paying symbols are those that include Royals. As soon as the free spins start, the game’s layout changes, and we start playing at night. At this point, the major characters transform into vampires.


The strange slot known as Castle of Terror initially caught us off guard. It seems to be a blend of literature and art, comparable to Apollo Pays Megaways but perhaps even more so in its tone. The gloomy vibe isn’t off-putting; rather, it increased Castle of Terror’s intrigue. Castle of Terror takes a more sober approach to vampire culture; its vibe is more akin to Immortal Romance than, say, Baron Bloodmore.
