Castle of Terror 2 Slot Machine Review

Players Slot Rating

Rate this slot

With Halloween nearby, it’s the perfect time for Castle of Terror 2 to be released by Big Time Gaming. It’s a developer that has always stood out in this industry, with unique mechanics and big prizes offering players exactly what they want. They manage to deliver a decent-looking theme here as well, though it’s usually not a strong point for them.

Castle of Terror 2 is going to be a slot with 1,024 ways to win that are available via 5x4 reels. With a prize of up to 20,160x the stake, there will be high volatility as well, but the RTP does go up to 96.48%. Among its major features, you get respins with different modifiers, as well as wilds and free spins.

Betting and Prizes

Giving it a spin requires a very small bet, of $0.10, but there is always the option of going higher, up to $10.

An excellent prize, 20,160x the round’s bet, awaits the player in Castle of Terror 2. High volatility is an unfortunate side effect of this sort of prize, but the slot remains fair if you pick the version with the 96.48% RTP (the game’s long-term odds are not the same as a single player’s results, though).

Castle of Terror 2 Game Features

You can get wild symbols to assist you in the formation of new combinations, but that’s all they will do for you. These substitute symbols can only land on reels 2-5, so paying you directly is out of the question.

Interestingly enough, the scatter symbols can be useful even if they only land once. When they show up just once, the reel they’re on will decide what kind of modifier will be active for the respin that follows. These modifiers are also available during free spins, but more on that below.

  • Brains (1st reel): additional Brain symbols in the game area.
  • Alive (2nd reel): up to 10x multiplier improves all the wins of that respin.
  • Shock (3rd reel): up to 5x multiplier wilds available.
  • Monster (4th reel): high-value symbols get turned into wilds when landing on the last four reels.
  • Horror (5th reel): one of the last four reels gets covered by wilds.

Should you land 2-3 scatters, then you get 10 free spins. You can also get there by getting at least one scatter during respins. The modifiers associated with the triggering scatters will be active for the free spins. There is also an increasing multiplier, going up by 1x after each win.

Theme & Design

It’s a Halloween-inspired design, with scary characters and creepy cemeteries, all shown next to or inside a Gothic-style castle that could very well be located in Transylvania. As symbols, you do get the six Royals, 9 to A, but you’re also looking at images of some toxic-looking lung, a Woman, an Old Man, and Brains.

Conclusion

Overall, Castle of Terror is a fun one to check out, especially with those modifiers and respins becoming so easily available (not that it’s easy to get a scatter, but it’s not quite at the difficulty of getting free spins, either). Want a slot with great potential, and you don’t mind high volatility? I suggest you check out Castle of Terror 2.
