Slot Mechanics & Feature Breakdown

Castle of Terror 2 plays on a 5x4 grid with 1,024 paylines, offering wins from left to right. Symbols include 9-A royals and high-paying icons like Brains, Lady, Old Man, and Lungs. Wilds appear on reels 2–5 and substitute for all symbols except scatters. The game’s core mechanics revolve around reel-triggered modifiers and escalating features that evolve during free spins, creating a dynamic and suspenseful gameplay loop.

Bonus Respin Modifiers

Landing a single scatter in the base game triggers a Bonus Respin, with the effect depending on the reel:

• Brains (Reel 1): Adds extra Brains symbols to all reels
• Alive (Reel 2): Applies a random win multiplier of x3–x10
• Shock (Reel 3): Wilds gain a random multiplier of x2–x5
• Monster (Reel 4): Random high-pay symbol becomes wild on reels 2–5
• Horror (Reel 5): Fills a random reel with wilds

These modifiers add strategic depth and unpredictability to every spin.

Free Spins Bonus

Triggered by 2 or 3 scatters—or via Bonus Respins—players receive 10 free spins. The round includes 2 or 3 active bonuses based on the triggering reels. A win multiplier starts at x1 and increases after each win. Features include:

• Brains: More Brains symbols on all reels
• Alive: Multiplier starts at x3–x10
• Shock: Wilds gain x2–x5 multipliers
• Monster: Random high-pay symbol becomes wild
• Horror: Random reel filled with wilds each spin

Landing 2+ scatters during free spins awards +4 spins, with each extra scatter adding +2 more.

Wild Mutation Feature

The Monster modifier transforms one of the high-paying symbols—Brains, Lady, Old Man, or Lungs—into wilds across reels 2–5. This mutation can occur during Bonus Respins or be carried into free spins, amplifying win potential. The feature adds thematic flair and strategic variability, especially when paired with multipliers.

Increasing Multiplier

During free spins, a win multiplier starts at x1 and increases by +1 after every winning spin. If the Alive modifier is active, the multiplier begins at x3, x5, x8, or x10. This escalating mechanic creates momentum and can lead to massive payouts, especially when combined with wild reels and symbol mutations.

Bonus Buy

Castle of Terror 2 offers two Bonus Buy options:

• 100x bet: Free spins with 2 active bonuses
• 300x bet: Free spins with 3 active bonuses

These options allow players to bypass the base game and dive straight into the slot’s most lucrative features, maintaining the top RTP of 96.48%.

Payout Potential: RTP, Volatility & Max Win
