SLOT SESSION // 1,500 SPINS
At Endorphina's declared 96.05%, a run of 1,500 spins at this bet averages out around -59× stake, shown as the dashed line. This one ended at 100×, about -1.7× 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 20 spins without a single win, spins 1,273 to 1,292.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -109× the stake, while 5 finished in profit, the best at +202.5×. 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.
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 Book of Santa Dice
This Book of Santa Dice review comes from my own play: I'm a casual player, and in October 2026 I ran 10 separate sessions of about 150 spins each, 1,500 spins in total, all at a flat 0.10 bet. Short answer: yes, it's worth playing if high volatility is your thing, because my run returned 106.7% against a stated RTP of 96.05%, and my biggest hit was 223.5x!
Each session was a fresh launch of the game in its own browser, with its own balance, so the balance reset between sessions. Every spin ran on play money, not real cash. The +100x I finished up across the whole test was pure luck over one sample: a slot's payout rate only settles over tens of thousands of spins, so treat everything below as one recorded run, nothing more.
Book of Santa Dice is an Endorphina release; the stated 96.05% RTP was read from the game's own server during the run, not copied from a catalog.
The stated volatility is high, and my 1,500 spins matched it. Wins landed on 27.5% of spins, and the four hits of 100x or better are what carried the run. The longest stretch without any win at all was 20 spins, and at my lowest point I was down 364x the stake.
The best moment of the whole test was the 223.5x hit! On a 0.10 bet, one spin paying like that is the whole reason to sit through the dry spells. Half of my sessions still ended in the red, so the swings are real on both sides.
Pros:
Cons:
Book of Santa Dice suits players who like high volatility and can sit through a 364x drawdown without flinching. If a 20-spin dead run or half your sessions ending in the red sounds miserable, this one isn't for you: the 27.5% hit frequency keeps small wins coming, but the game is built around rare bigger hits, with an advertised ceiling of 5,000x.
I'm giving it 10/10: it plays exactly like the high-volatility game it claims to be, and a run like this one shows what the good side of that can look like. That's one lucky sample talking, not a guarantee, and your run can look completely different. After 1,500 spins and a finish at +100x, though, I'm not pretending I didn't have a blast.
18+. Gamble responsibly: slots don't make money, so treat them as paid entertainment and only bet what you can afford to lose.
The RTP is 96.05%, which sits right around the industry average of about 96%.
The maximum win is 5,000x the player's bet.
Yes, a free demo is available to try the game without risk.
Endorphina's Book of Santa Dice, a December 2024 release, arrives with numbers that define what to expect: 96.05% RTP, high volatility, and a 5,000x max win. These figures set the tone before the first spin: this is a slot built for players who can tolerate variance in pursuit of larger payouts rather than steady, incremental returns.
The game operates on a 5x3 grid. Wild symbols substitute for regular icons to complete paying combinations, while Scatter symbols count wherever they land.
Free Spins open a bonus round played without further stakes. Expanding Symbols can stretch to cover entire reels. Buy Bonus lets players pay to enter the bonus directly. The Gamble feature lets players risk a win to try to increase it, though the statistical reality favors the house over repeated attempts.
At 96.05%, Book of Santa Dice sits essentially at the industry average of around 96%. Where the game makes its statement is volatility. High volatility translates to sessions characterized by longer dry spells punctuated by occasional substantial hits. Bankroll management matters here; stretches without wins are expected, and the 5,000x ceiling represents solid potential.
Christmas and Dice converge here, suggesting a holiday-season aesthetic applied to straightforward, symbol-matching mechanics. Expect a festive presentation.
Book of Santa Dice earns its 5/10 rating through competent execution without standout distinction. The RTP is average and the volatility demands patience. It suits players who specifically want a Christmas-themed slot with buyable bonuses and are comfortable with high-variance sessions. The free demo lets you test whether the rhythm matches your preference.
