Cathedral 9 is designed for high-risk, high-reward players who enjoy complex features and dark, atmospheric themes. The game’s scatter pays system means wins occur when 8 or more matching symbols appear anywhere on the grid, rather than traditional paylines.

Theme and Visual Design

The first thing you’ll notice about Cathedral 9 is its gothic aesthetic. The game is set inside a crumbling cathedral, with stained glass windows, eerie statues, and flickering candlelight creating a haunting atmosphere. The soundtrack features choral chants and organ music, adding to the sense of mystery and grandeur.

Unlike bright and cheerful slots, Cathedral 9 leans into dark fantasy vibes, similar to titles like Phoenix Graveyard or Nightmaker. This makes it perfect for players who love immersive storytelling and moody visuals.

Symbols and Payouts

Cathedral 9 uses a scatter pays mechanic, meaning you need at least 8 matching symbols anywhere on the grid to score a win. Here’s a breakdown:

• Low-paying symbols: Four pip-style icons (clubs, diamonds, hearts, spades).
• High-paying symbols: Gothic artifacts like chalices, crosses, and relics.
• Wild Symbol: Substitutes for all pay symbols and offers the highest payout when forming a full grid.

Big Symbols (2×2, 3×3, or 4×4) can also appear, covering multiple positions and boosting your chances of landing massive wins.

Core Features and Mechanics

Cascading Wins

Every time you land a winning combination, the symbols disappear, and new ones drop from above. This can trigger chain reactions, leading to multiple wins in a single spin.

Feature Reel

Above the main grid is a 2×6 Feature Reel that holds special symbols like multipliers, mystery coffins, and blockers. When wins occur, these features can drop into the main grid, activating powerful modifiers.

Mystery Coffins

These are the heart of Cathedral 9’s gameplay. When a coffin reaches the bottom of the grid, it activates and reveals a random symbol. Super Mystery Coffins add multipliers to the Global Multiplier, which persists during bonus rounds.

Holy Collect

Triggered randomly, this feature adds 3–6 coffins to the grid, increasing your chances of unlocking big wins.

Entombed Feature

When the Entombed symbol covers the entire feature reel, all symbols on the grid transform into a single payout symbol, guaranteeing a massive win.

Bonus Rounds and Free Spins

Landing 3 or more Bonus Symbols triggers the Free Drop Bonus Game. Each bonus symbol awards 2–4 free drops, and additional symbols during the bonus add extra spins.

The ultimate goal? Unlock the Super Bonus, which is played exclusively with Super Mystery Coffins. This is where the game’s full potential shines, as multipliers stack and payouts can skyrocket toward the 25,000x max win.

X-iter™ Feature Buy Options

ELK Studios includes its signature X-iter™ system, allowing players to buy into different bonus modes:

• 3x Bet: Increased chance of triggering the bonus.
• 10x Bet: Guaranteed feature activation.
• 500x Bet: Direct entry into the Super Bonus round.

This feature is ideal for players who prefer instant action rather than waiting for bonuses to land naturally.

RTP, Volatility, and Hit Frequency

• RTP: 94% (lower than the industry average of 96%).
• Volatility: High – expect long dry spells but massive payouts when features align.
• Hit Frequency: Around 24.9%, meaning roughly 1 in 4 spins results in a win.

Cathedral 9 is not for casual players. Its high volatility and low RTP make it a game for those who enjoy big risks and epic rewards.

Mobile Compatibility

Like all ELK Studios titles, Cathedral 9 is fully optimized for mobile and desktop play. The game runs smoothly on iOS and Android devices, maintaining its rich graphics and immersive sound design.

Tips to Maximize Your Experience

1. Start Small: With high volatility, it’s wise to begin with smaller bets to gauge the game’s rhythm.
2. Use X-iter Wisely: If your bankroll allows, buying into the Super Bonus can significantly increase your chances of hitting the max win.
3. Manage Your Bankroll: Set limits and stick to them. Cathedral 9 can be streaky, so patience is key.
4. Play for Fun First: Try the free demo mode before wagering real money to understand the mechanics.
