Castle of Terror 2 Slot Verdict
The Castle of Terror 2 slot from Big Time Gaming is a far superior game than the first. It is more immersive, more entertaining, it has better design, and yes, it’s just a general improvement. With that said, this Halloween slot, compared to others from other developers, does come across as being somewhat mediocre. The features and bonuses are lacking, and the only real gaming benefit is the bonus multiplier. It feels that this game should have offered more, but what do you think?
Play the free slots demo with or without the aid of a seance or Ouija board by joining Casinos.com, where 75% of the services aren’t as bad as our slot reviews.

[The following takes place in the Land of the Dead]
Greetings from the Land of the Dead. I have been contacted from the Human realm to present you with the online slot of The Castle of Terror 2 from Big Time Gaming. On first glance, it is one of the most impressive upgrades from an original slot that I have seen. The game is darker, more sinister, and generally looks better.
Is the gameplay an improvement? Only one way to find out. I set the stake value to $3 per spin and play twenty-five auto spins. The immersive quality makes this slot machine a white-knuckle-ride that comes with frequent hits. Of the first ten spins, three wins land, amounting to $8. The hit rate then dropped to zero for the next thirteen spins until the next win, which came in at $12.
I decided to play ten more spins with an increased betting value of $5 per spin. The gaming improves, and with the seventh spin of my $5 bet, I land three scatters to unlock the bonus game and play ten free spins.
The gaming propels me into the castle, where I play the bonus round within the mad scientist's laboratory. Ghouls and Frankenstein appear, and the round plays out with an energy that was completely void in the first game. As wins land, the multiplier grows and grows, reaching 12x, resulting in a big win of $140. As the bonus ends, I settle the game and cash out my winnings to spend in the Land of the Dead tourist gift shop. Mmmwahahaha.
