SLOT SESSION // 1,500 SPINS
At Endorphina's declared 96.03%, a run of 1,500 spins at this bet averages out around -60× stake, shown as the dashed line. This one ended at -37×, 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 30 spins without a single win, spins 807 to 836.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -102× the stake, while 3 finished in profit, the best at +207.5×. 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.
One frame 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 Book of Lady
I spent October 2026 playing Book of Lady from Endorphina, and this Book of Lady review comes straight from that run: 10 separate sessions, about 150 spins each, 1,500 spins total at a flat 0.10 stake. Short version: it's a 5/10, an okay pick for casual players who like medium volatility, and nothing more. The run returned 97.5% against a stated RTP of 96.03%, my best single hit was 206.5x, and the whole test still ended at -37x the stake.
That 96.03% was read from the game's own server during the run, not copied from a catalog. And 97.5% is what this one recorded run paid back, not the game's payout rate; that only settles over tens of thousands of spins. All 1,500 spins ran in free-play mode, so the stake sat in a play-money wallet, not in real money.
Book of Lady is listed at medium volatility, and the run matched that label. Wins landed at a 29.5% rate, so small hits kept the balance ticking and quiet patches stayed short most of the time. The bigger ones were rare: 3 hits of 100x+ over 1,500 spins, with 206.5x the best of the lot.
Medium doesn't mean gentle, though. The longest stretch without any win at all ran 30 spins, and watching the counter climb that high on a flat stake gets old fast. The deepest slide across the combined run cost 307x the stake, a deep dip for a mid-volatility game.
Pros:
Cons:
Book of Lady suits casual players who want a medium-volatility slot with frequent small wins and modest stakes. Anyone chasing the 5,000x max win should know the best I saw in 1,500 spins was 206.5x.
Expect swings along the way. The deepest drawdown in this test reached 307x the stake, a reminder that even a medium-volatility slot can lean against you for a long stretch.
My score is 5/10: the run paid back above the stated RTP, yet most sessions lost money and the top end never showed. It's an honest, middle-of-the-road slot, fine for a relaxed spin and easy to skip if you want fireworks.
18+. Play responsibly: slots are entertainment, not a way to make money, so only bet what you can afford to lose.

The 96.03% RTP sits around the 96% industry average. Medium volatility strikes a balance between hit frequency and payout size, producing steadier sessions than high-variance play without the frequent small wins of low-volatility play. The 5,000x max win marks a solid ceiling — respectable potential without reaching the highest tiers.
Luxury and Royal themes combine to evoke rank, opulence, and ceremonial formality. The expected mood leans toward prestige.
Book of Lady is a 5/10 release. The RTP sits only at the average, the 5,000x ceiling is solid rather than exceptional, and the feature list reads like a checklist. Players who appreciate medium-volatility pacing may find it serviceable. Try the free demo to judge whether the atmosphere suits your taste.
