SLOT SESSION // 1,500 SPINS
At Endorphina's declared 96.04%, a run of 1,500 spins at this bet averages out around -59× stake, shown as the dashed line. This one ended at -507×, about 8.5× further down than the average run. 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 470 to 488.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -100× the stake, and the only one in profit finished at +26.5×. 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 Vlad
This Book of Vlad review comes from 1,500 spins I played in October 2026, split into 10 separate sessions of about 150 spins each at a flat 0.10 stake. My verdict up front: I wouldn't bother again. The run returned 66.2% against a stated RTP of 96.04%, only 1 of the 10 sessions finished above water, and my biggest hit was 100x.
Each session was a fresh launch of the game in its own browser with its own balance, and every spin ran in free play mode, so the stake sat in a play-money wallet, not real money. The numbers below are the whole set added up.
One thing to be clear about: 66.2% is the return this run recorded, not the game's payout rate. A game's payout rate only shows up over a far longer sample.
Book of Vlad is labeled medium volatility, and the 26.8% hit frequency fits that label, since wins showed up regularly. The problem is what they paid. A hit frequency like that combined with a 66.2% return implies most hits were small. The balance kept sliding, and the deepest hole I sat in was 513x the stake.
The worst cold patch was 19 spins without a single win. The one moment that broke the pattern was a 100x hit, my only big win of the whole test.
Did it feel like medium? Not to me. One run can't prove or disprove a label, but a 513x drawdown and a finish at -507x felt heavier than the word "medium" suggests.
Pros
Cons
Who might still give Book of Vlad a shot: someone who likes frequent small wins and treats the advertised 5,000x as background noise, because my best in 1,500 spins was 100x. Even then, the bankroll has to sit through holes like the 513x drawdown I recorded. Surviving a dip that deep doesn't mean the money comes back.
Who should skip it: anyone expecting the stated 96.04% to show up in an evening. After a 66.2% run with 1 winning session in 10, I put myself in that group. The 2/10 reflects what I recorded: a return far under the stated figure, one big win, and a combined result that ended at -507x.
18+. Gamble responsibly: slots don't make money, so only stake what you can afford to lose.

Book of Vlad arrives from Endorphina with Expanding Symbols as its headline mechanic, backed by a crowded feature set that tries to cover every base. The slot layers Free Spins, Symbol Collection, Buy Bonus, Gamble, and Jackpot elements onto a 5x3 grid, making it a busy package that may please players who want options more than focus.
The action unfolds on a fixed 5x3 grid. Wild symbols substitute for regular pays, while Scatter symbols count wherever they land. The base game also incorporates Symbol Collection, gathering designated symbols toward a goal that unlocks something.
Expanding Symbols can grow to cover entire reels. Free Spins open a bonus round played without further stakes.
The Buy Bonus lets players pay to enter the bonus directly. The Gamble feature lets players risk a win for a larger one.
The 96.04% RTP sits essentially at the industry average of 96%. Medium volatility produces a balanced session profile with moderate dry spells between hits. The 5,000x max win qualifies as solid potential.
This is a Vampire, Horror, and Gothic slot, trading on a dark, undead atmosphere.
Book of Vlad is a 5/10 release that tries to do too much with too little focus. The Expanding Symbols mechanic delivers genuine tension, but the surrounding feature bloat dilutes the experience. The medium volatility and average RTP offer no particular hook. Players who appreciate Symbol Collection and a long feature list may find enough to occupy them; those seeking a tight, memorable vampire slot will likely move on.
