Cathedral 9 by ELK Studios is a 6-reel, 5-row slot with a feature reel at the top of the grid and a stated maximum win potential of 25,000x bet. The game includes wilds, a global multiplier, symbol collect mechanics, synced symbols, and state-based features that remain active between rounds.
Core features include Mystery Coffins, which reveal matching symbols across the grid, and the Entombed mechanic, where the full feature reel can transform symbols into payout symbols. Holy Collect can carry state between game rounds and add 3 to 6 coffins when triggered, while the feature reel controls how feature symbols enter play.
Players can use the demo version to play for free and practice before playing for real money. Cathedral 9 also includes a free drop bonus game triggered by 3 or more bonus symbols, with extra free drops awarded during the round. Landing all 9 payout symbol types unlocks the super bonus, which is played with only super mystery coffins.
