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 -105×, 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 17 spins without a single win, spins 698 to 714.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -98× the stake, while 4 finished in profit, the best at +149.5×. 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.
7 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 Book of Sam
This Book of Sam review comes from a full test I ran in October 2026: 10 separate sessions, 1,500 spins in total, all at a flat €1.00 stake. My honest advice: skip this one. Across the whole run the slot returned 93.0% against a stated RTP of 94.00%, my best hit was 137x, and only 4 of the 10 sessions ended in profit. Every spin ran in free mode with play money, so no real cash was on the line.
Book of Sam carries a high volatility rating, and my run matched it. Wins landed on 23.2% of spins, so most spins paid nothing. The dry patches were the real grind: my longest winless stretch ran 17 spins, and at its deepest point the combined run across all 10 sessions sat 380x the stake in the red.
Every session was a fresh launch of the game with its own balance. Only 4 of the 10 finished above water.
The one moment that broke the pattern was a 137x hit, my only 100x+ win of the whole test. Against an advertised max win of 10,000x, that was the best the game showed me, and it came nowhere near saving the run: the test finished at -105x the stake overall.
Pros:
Cons:
Book of Sam suits one kind of player: someone who genuinely enjoys high volatility and has a balance deep enough for swings like mine, where the combined run across all 10 sessions went 380x the stake into the red at its lowest point. That depth only says how much pain you can absorb; nothing in my run suggests the game pays you back for waiting. Everyone else, especially anyone hoping the stated 94.00% means steady returns, should stay away.
To be fair, 1,500 spins is one recorded run, not a measurement of the game's true payout rate, which only settles over tens of thousands of spins. But I can only judge what I saw, and what I saw was a long grind with one decent hit.
The 2/10 comes down to simple math: 1,500 spins, one 100x+ win, 40% of sessions in profit, and a final balance of -105x the stake.

Book of Sam arrives as a January 2023 release with a 10,000x max win that immediately signals high-stakes potential. The rest of the package will need scrutiny before you decide whether the juice is worth the squeeze.
The 5x3 grid keeps things familiar, a straightforward Egyptian slot foundation with five reels and three rows. Wild symbols substitute for regular icons to complete winning lines, while Scatter symbols serve as the gateway to bonus content. Respins give you extra shots at connecting combinations without an additional bet. The Expanding Symbols mechanic means certain icons can stretch to cover entire reels, amplifying your chances on any given spin.
The feature set layers in several modern mechanics. Free Spins form the core bonus round. The Buy Bonus option lets you purchase direct entry to bonus play. Multipliers weave throughout, compounding wins when conditions align.
Book of Sam occupies crowded territory: the Egyptian slot genre, filtered through a Vegas lens with American styling and the "Book of" format. Fantasy elements mingle with the desert aesthetic, creating a hybrid atmosphere that borrows from multiple visual traditions. The result feels less like a coherent world and more like a checklist of proven slot motifs assembled for market-tested appeal.
The 94.00% RTP sits clearly below the 96% industry average, meaning the house edge runs steeper than most contemporary releases. For a high volatility slot, this combination proves particularly punishing: the math model already favors fewer, larger hits over steady returns, and the below-average RTP extends the dry spells between those moments. The 10,000x max win is genuinely impressive, high-potential territory that explains why some players will tolerate the rougher math. But that ceiling exists as theoretical possibility rather than practical expectation, and the path to reaching it demands significant bankroll headroom and tolerance for variance.
Book of Sam earns its 3/10 rating through a fundamental tension: the features and max win suggest ambition, while the execution undercuts itself with below-average returns and a derivative theme mashup. The 94.00% RTP in a high-volatility package creates a demanding experience that rewards only the most fortunate or most patient. For players specifically seeking that 10,000x ceiling and willing to endure the grind, the math might justify the attempt. You can test whether the volatility suits your taste using the free demo.
