Big Time Gaming (BTG) invites players back into the eerie laboratory of Castle of Terror II, the sequel to its chilling original slot. This new release amplifies every aspect of the first game—bigger bonuses, more electrifying features, and even scarier thrills.
The horror-themed slot places players in a sinister lab where experimental chaos reigns. The experience kicks off with Bonus Respins, which are triggered by landing Scatter symbols. Each Scatter brings a different type of monstrous twist to the reels depending on where it lands, unleashing features such as:
- Brains: Extra Brains appear across the reels.
- Alive: A random Win Multiplier is applied to all wins.
- Shock: Wilds activate random multipliers.
- Monster: A random symbol transforms into a Wild across reels two to five.
- Horror: A random reel becomes completely Wild.
If another Scatter lands during a Bonus Respin, the mayhem escalates, unlocking 10 Free Spins for a truly “spine-tingling time.” Two or three Scatters intensify the experiment further, awarding another set of 10 Free Spins.
Free Spins with Electrifying Enhancements
During Free Spins, the Win Multiplier starts at 1x but increases with every successful spin, amplifying potential rewards with each electric surge. Every Free Spin also carries additional Bonuses based on the position of the triggering Scatters. The bonuses interact and collide, creating a sequence of unpredictable and thrilling moments that keep players on edge.
As the chaos unfolds, the potential for extra spins grows—when multiple Scatters land during Free Spins, the “machine gun” of bonuses surges again, granting four additional spins plus two more for every Scatter beyond the second.
Control the Madness with Bonus Buy
Players who can’t wait to unleash the horror can opt for the Bonus Buy feature. For 100x their stake, they can instantly trigger 10 Free Spins with two active bonuses. Those craving greater intensity can invest 300x their stake to unlock 10 Enhanced Free Spins featuring three bonuses for maximum volatility and fright-filled excitement.
Castle of Terror II delivers a high-voltage experience that blends creativity, suspense, and explosive win potential. With an RTP of 96.48%, the slot challenges players to take on a monstrous experiment that grows wilder with every spin.
A Word from Big Time Gaming
Nik Robinson, CEO at Big Time Gaming, said: “Castle of Terror II is a terrifying slot that’s not for the faint-hearted. Players find themselves in a spooky lab where creepy experiments take place, but if they can hold their nerve, there are plenty of bonus features to discover.”
Robinson added, “Castle of Terror II really does put players on the edge of their seats with heart-stopping action and plenty of unexpected jump scares. Think you have what it takes to enter the Castle of Terror for the second time? There’s only one way to find out.”

Big time gaming has always been a power house of high octane slots that can bring explosive wins and great times. It's good to see them making a second Version of an already great game with even more terrifying bonus action.
