Cathedral 9 by ELK Studios is a visually striking 6-reel, 5-row video slot that plunges players into a mystical world of ancient relics and divine riches. With a Pay Anywhere mechanic, cascading symbols, and a feature row packed with wilds and multipliers, this high-volatility game offers a thrilling chase for up to 25,000x your bet. The slot’s religious theme is woven into every detail—from the sacred coffins to the nine legendary artifacts that unlock the super bonus. Cathedral 9 is a bold blend of spiritual symbolism and explosive gameplay, ideal for players who crave immersive slots with layered features and high payout potential.
Cathedral 9 is played on a 6x5 grid with a dynamic feature row above the reels. The game uses a Pay Anywhere system, allowing wins from symbol clusters across the grid. Cascading symbols and synced reels enhance the gameplay, while the feature row introduces wilds, blockers, and multipliers. With a hit frequency of 24.9%, the slot balances frequent action with high-risk rewards.
Mystery Coffins appear on the grid and activate when they reach the bottom. All coffins in view reveal the same symbol, creating powerful payout clusters. Super Mystery Coffins add their multiplier value to the persistent global multiplier, which applies to all wins. This feature adds suspense and strategic depth to each spin, especially when multiple coffins align.
The Entombed feature triggers when the entombed symbol fully covers the feature reel. When activated, all symbols on the grid are replaced with a single payout symbol, creating massive win potential. This transformation mechanic is one of Cathedral 9’s most visually dramatic and rewarding moments, especially when paired with active multipliers or synced reels.
Holy Collect can trigger during any initial drop. Holy blockers from the feature reel contribute to the collect meter, which persists between rounds. Once activated, it adds 3–6 coffins to the grid, increasing the chance of triggering Mystery Coffins and boosting symbol synergy. This feature rewards long-term play and builds anticipation across spins.
Landing 3 or more bonus symbols triggers the Free Drop Bonus Game. Each bonus symbol awards 2–4 free drops, and additional bonus symbols during the round add more. Winning on all nine payout symbol types during the bonus unlocks the Super Bonus, played exclusively with Super Mystery Coffins. This layered bonus system offers escalating rewards and a clear path to the game’s highest payouts.
Cathedral 9 includes ELK Studios’ signature X-iter feature, allowing players to buy into various bonus modes. Options include:
These buy-in options cater to high rollers and strategic players looking to bypass base game variance and dive straight into the action.
Cathedral 9 offers a RTP of 94%, which is slightly below the industry average but balanced by its high reward ceiling. The slot’s volatility is rated 4/5, meaning wins are less frequent but potentially massive. The standout figure is the max win of 25,000x your bet, achievable through the Super Bonus and global multipliers. This makes Cathedral 9 a high-risk, high-reward experience for seasoned slot enthusiasts.
