Asylum Files Slot Review – Demo, RTP & Features

Asylum Files is a horror-themed video slot from Revolver Gaming, taking players into Blackwood Asylum, a disturbing institution filled with restrained patients, unsettling medical staff, and mysterious experiments.

This slot machine game combines the developer’s Coins series mechanics with stacked symbols, eyeball collections, Free Spins, multipliers, and a Bonus Wheel featuring a Progressive Jackpot opportunity.

The atmosphere draws on classic asylum horror, with gloomy corridors, industrial machinery, and characters that look as though they belong in a sinister medical experiment. A nurse, a doctor with an exposed brain, and chained patients contribute to the game’s unsettling appearance.

The laboratory theme also extends into the bonus mechanics. Eyeballs collected from the reels are transferred into vats of bubbling liquid, while a mechanical Bonus Wheel presents rewards through classified patient files.

Asylum Files slot machine uses 5 reels, 3 rows, and 20 paylines. It has medium to high volatility, a highest listed RTP of 96.20%, and a maximum advertised payout of 12,321x the stake. Bets range from €0.20 to €20 per spin.
