SLOT SESSION // 1,500 SPINS
At ELK Studios's declared 94%, a run of 1,500 spins at this bet averages out around -90× stake, shown as the dashed line. This one ended at 86.9×, close to where the average run lands. One session swings hard either way; the gap is the swing, not the game's payout rate.
The driest stretch ran 19 spins without a single win, spins 622 to 640.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -54.9× the stake, while 3 finished in profit, the best at +211.8×. These are consecutive blocks of one continuous session, not 10 separate sittings: the balance never reset. Block 1 was played through the game's own interface; the rest replayed the bet call directly. Same numbers either way; only the first can be photographed.
5 frames captured by the rig during the recorded session. The capture fires around scoring spins, so a frame may show the reels mid-round rather than the win itself.
Our review of Cathedral 9
I spent October 2026 playing Cathedral 9 from ELK Studios, and this Cathedral 9 review covers the full run: 10 separate sessions, about 150 spins each, 1,500 spins in total, all at a flat €1.00 stake. Short version: this is a high-volatility slot that treated me well, and if you can handle real swings, it's worth playing. My run returned 105.8% against a stated RTP of 94.00%, and my single biggest hit was 124.1x!
Two things before the numbers. Each session was a fresh launch of the game in its own browser with its own balance, so the balance reset between sessions, and every spin ran on play money, not real cash. And the 105.8% was luck over this one sample, not a property of the slot and not a promise of what it'll do for you.
Cathedral 9 is rated high volatility, and my 1,500 spins backed that up. Wins landed on 23.9% of spins, so roughly three spins out of four paid nothing, and my longest run without any win at all was 19 spins. The worst drawdown went 221x the stake deep.
Only 3 of the 10 sessions finished above water. But when the slot paid, it paid properly: 4 wins of 100x+, peaking at 124.1x! That's the whole game in one line, long quiet patches and then a hit that flips the session. Added up across the full set, my balance ended at +87x the stake.
Pros
Cons
Cathedral 9 is for players who enjoy high volatility and can sit through a deep drawdown without tilting. The worst dip and the longest dry spell, both covered above, show what you're signing up for, so you want a balance where that kind of drop is a bad evening, not a bust. If dry spells rattle you or you want steady small returns, skip it.
I'm scoring it 10/10, and I'll own what that score is: it's about this run, 105.8% back, 4 wins of 100x+, and a finish at +87x the stake. As I said up top, that was luck, and a slot's payout rate only settles over tens of thousands of spins. My verdict from the lead stands, though: for a player who likes swingy games, this one is easy to recommend.
18+. Gamble responsibly: slots don't make money, so only bet what you can afford to lose.

Cathedral 9 arrives from ELK Studios as an October 2025 release. The slot wraps a grim medieval horror aesthetic around a high-volatility engine with a 25,000x max win ceiling.
The 6x5 grid operates with tumbling mechanics, where winning combinations vanish and fresh symbols cascade into place, allowing multiple wins from a single spin. Wilds substitute for standard symbols, while multipliers amplify payouts when they factor into winning combinations. Mystery symbols add unpredictability by revealing matching symbols when they land, and a symbol collection mechanic tracks specific symbols toward some form of accumulated goal. The buy bonus option allows direct access to the bonus.
Free spins function as the core bonus round.
The 94.00% RTP sits noticeably below the ~96% industry average. Coupled with high volatility, Cathedral 9 demands both patience and a substantial bankroll cushion; dry spells between significant hits run long, and the below-average return rate compounds the risk. The 25,000x max win qualifies as high-potential territory.
Medieval horror provides the atmospheric foundation. The visual approach likely emphasizes shadow and creeping dread.
Cathedral 9 earns its 4/10 rating through a punishing math model. The below-average RTP paired with high volatility creates a demanding experience. Dedicated high-volatility hunters with substantial bankrolls might still enjoy it, particularly those drawn to dark atmospheric settings.
