Black Souls

Black Souls is a slot from developer OneSpin, confirmed with a 96% RTP, though detailed reel, payline and volatility information hasn't been published for this title yet. Going purely by the name, this reads as a dark-fantasy or gothic-horror themed release — the kind of atmospheric, shadow-drenched slot built around spectral imagery, cursed relics or tormented spirits rather than anything bright or cheerful.

A gothic, atmospheric theme

OneSpin's naming choice here suggests a game leaning into moody lighting, haunting sound design and a symbol set built around skulls, wraiths or dark magic iconography — the kind of visual language that's become a reliable staple for slots aimed at players who prefer their reels a little sinister. Without confirmed screenshots or feature breakdowns available yet, it's worth checking the developer's own preview material once the game is closer to release for the exact visual direction.

Reading the 96% RTP

A 96% RTP is exactly the figure most players in the industry point to as the benchmark for a "fair" slot. Over a sufficiently large number of spins, Black Souls is designed to return £96 for every £100 staked, with the house holding onto a standard 4% edge. It's not the most generous RTP featured in this roundup, but it's a solid, dependable number that won't leave players feeling short-changed compared with the wider market.

Volatility: currently unconfirmed

OneSpin hasn't published an official volatility rating for Black Souls, so treat the first handful of sessions as reconnaissance. Playing smaller stakes initially will help you get a feel for the game's natural rhythm — how often it pays, and roughly how big those payouts tend to run — before you decide whether to commit larger bets.

Max win and stake range: to be confirmed

There's no published maximum win multiplier or bet range for Black Souls at this stage. As with any newly listed slot, check the paytable and info screen directly inside the game once it's live, since these figures are frequently added or revised closer to a full release.

Final verdict

A dependable 96% RTP paired with a suitably ominous gothic theme makes Black Souls worth keeping an eye on, even with several details still to be confirmed. Once it's available, the smartest first move is to spin through the free demo at johnessyslots to get a feel for the atmosphere and pacing before deciding whether to wager real money on it.
