SLOT SESSION // 1,500 SPINS
At Relax Gaming's declared 96.11%, a run of 1,500 spins at this bet averages out around -58× stake, shown as the dashed line. This one ended at -147.5×, about 2.5× 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 12 spins without a single win, spins 1,445 to 1,456. The best win of the whole session had landed 30 spins before it began.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -103× the stake, while 3 finished in profit, the best at +163×. 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 Power
This Book of Power review comes out of 1,500 spins I played in October 2026 on Relax Gaming's slot, split into 10 separate sessions of about 150 spins each. Each session was a fresh launch with a balance that reset between sessions, all at a flat 2.00 stake in free play, and the figures below are the whole set added up. The short answer: I'd skip it. My return across the set came to 90.2% against a stated RTP of 96.11%, my best single win was 160x, and only 3 of the 10 sessions finished above water.
One thing to be clear about: even added together, the 1,500 spins from 10 separate sessions are not a measurement of the game's payout rate. That only settles over tens of thousands of spins.
The stated volatility is high, and the behavior matched it, just in the least rewarding way: big wins stayed rare and the slide between them ran deep. A 33.0% hit frequency meant something landed about every third spin, and the longest stretch without any win at all was 12 spins, so dead spells stayed short. The frustration was what those hits paid. The whole test produced 1 (100x+) big win, and the best result, 160x, sat a long way from the advertised 15,000x.
The deepest drawdown reached 527x the stake, and the set closed at -147x. A best win that size barely makes a dent in a hole that deep.
Pros:
Cons:
The only player I could point toward this slot is a committed high-volatility fan with a bankroll deep enough to sit through a 527x drawdown, and even then I'd say judge it in free play first. Anyone after steadier sessions, or hoping to see anything close to the advertised 15,000x, won't find encouragement in my run.
I score it 2/10. The stated 96.11% and the 15,000x ceiling read well on paper, but 1,500 spins gave me a best win of 160x, a long slide, and not much else.
18+. Gamble responsibly: slots don't make money, so only bet what you can afford to lose.

The standout figure in Book of Power is right there in the numbers: a 15,000x max win that puts this Relax Gaming slot firmly in high-potential territory. That ceiling, paired with high volatility, signals a game built for players who can stomach dry spells.
The action unfolds on a straightforward 5x3 grid. Wild symbols substitute for regular symbols to complete winning combinations, while Scatter symbols count wherever they land. The Expanding Symbols mechanic can stretch winning combinations across the reels, and Multipliers ramp up the value of successful spins.
Free Spins open a bonus round played without further stakes. The Gamble option lets players risk their winnings for a shot at bigger payouts.
Players who prefer direct access can use Buy Bonus to enter the bonus directly. Ante Bet offers an alternative path, increasing the stake to improve bonus trigger odds without guaranteeing entry.
The 96.11% RTP sits just above the 96% industry average. The real character of Book of Power comes from its high volatility. Expect fewer hits overall, longer stretches between meaningful wins, and the need for disciplined bankroll management.
That 15,000x max win is the headline attraction. For most players, the ceiling represents aspiration rather than expectation.
Book of Power draws from Egyptian and Mythology themes, evoking ancient rituals, forgotten deities, and desert mystery.
Book of Power is a 6/10 release that delivers exactly what the numbers suggest: a high-variance Egyptian slot with genuine upside but long dry spells. The 15,000x max win and above-average RTP give it mathematical credibility. Players who can tolerate volatility will find a competent entry. Those seeking steadier sessions are poorly served here.
