RTP Verdict

Industry-Standard Maths

Book of Shadows sits within a percentage point of the 96.00% industry norm, so its return is neither an argument for nor against playing it. What separates it from its neighbours is how it pays — the rhythm of small wins against rare big ones — which is what the measured data further down describes.

Frequently Asked Questions

What is the RTP of Book of Shadows?
Book of Shadows by Nolimit City has a theoretical RTP of 96.01%, which is average for online slots. This is the figure the game's maths returns over its full lifetime, certified by an independent testing lab — not a reading from recent play.
Is Book of Shadows paying well right now?
There is no honest way to answer that, and we would rather say so than invent a number. Reading a single slot's actual return to within a percent takes tens of millions of spins on that one game, because one large hit outweighs weeks of ordinary play. Any site quoting you a slot's "RTP today" is quoting noise. What we do publish, where our tracker has recorded enough real bets, is how often the game pays at all — a figure that settles far faster and is shown on this page with its confidence interval.
Do slots go hot or cold?
Not in any way you can use. We tested our own recorded bet series for the serial correlation a genuine streak would leave behind, using Ljung-Box autocorrelation tests, and found none — the results are indistinguishable from independent draws, which is exactly what a certified random number generator is meant to produce. A game that has paid well recently is no more and no less likely to pay on the next spin.
Who made Book of Shadows and where can I play it?
Book of Shadows is developed by Nolimit City. You can play it on Duel.com and other crypto casinos that carry Nolimit City titles. The game's maths is identical wherever you play it — operators cannot change a certified RTP, though some games ship in several certified versions and an operator may choose which to run.
How does Book of Shadows's RTP compare to other Nolimit City slots?
Book of Shadows returns 96.01%, which is average for the industry (average 96.00%). The spread within a single studio is usually wider than the gap between studios, so it is worth comparing title by title — our Nolimit City page lists every one we hold with its published return.
What does the industry-standard maths verdict mean for Book of Shadows?
Book of Shadows sits within a percentage point of the 96.00% industry norm, so its return is neither an argument for nor against playing it. What separates it from its neighbours is how it pays — the rhythm of small wins against rare big ones — which is what the measured data further down describes.
Is Book of Shadows worth playing?
Book of Shadows offers a 96.01% return, which matches industry norms. On the maths it is neither a bargain nor a trap. Pick it if the theme and the feature set appeal — and check its measured hit frequency on this page if you want to know whether it pays in a steady trickle or in rare bursts.
