Book of Shadows (Nolimit City) RTP review: 96.01% (configurable)
What 96.01% RTP means on Book of Shadows
Book of Shadows carries a published RTP of 96.01%, a theoretical house edge of roughly 3.99% over the long run. Because Nolimit City ships this game in multiple RTP builds, that edge only holds where a casino licenses the top version; a lower build quietly raises the edge against you, which is exactly why we flag configurable titles instead of quoting the headline unqualified. As always, RTP is a long-run average over millions of spins, not a per-session promise: the edge is real and permanent, and a high RTP never turns a slot into a reliable source of income.
Volatility, max win & features
Volatility is rated very high (5/5). Expect long gaps between meaningful wins, with most of the return concentrated in the bonus — a friendly RTP does not make this a smooth, low-risk grind. The top prize is capped at 30,338x your stake, and the headline features are shadow rows, lucky locks respins, expanding symbol, free spins.
What to know before you play Book of Shadows
- Check the RTP build. Nolimit City licenses Book of Shadows at 96.19% / 96.07% / 96.01% — open the in-game "i" screen and confirm you're on 96.01% before you commit a bankroll.
- Bankroll for variance. At very high volatility the bonus carries the return — size your stake for long dry spells, not the 30,338x ceiling.
- Feature-buy (not in the UK). Buying the bonus shifts the effective RTP — the in-game info screen shows the buy-specific figure.
- High RTP is not profit. 96.01% still leaves a 3.99% long-run house edge; it lowers the cost of play, it never flips the odds in your favour.
Strengths & weaknesses
Strengths
- 30,338x max-win ceiling
- Mechanics that stand out: Shadow Rows, Lucky Locks respins, Expanding symbol
- Transparent, provider-sourced RTP figure with a stated source
Weaknesses
- Configurable — some casinos license a lower RTP build, so you must check the paytable
- The headline RTP applies only at a specific stake (RTP is row-dependent: 96.01% at 3 rows / 10 lines (default), 96.07% at 4 rows, 96.19% at 5 rows — selecting more Shadow Rows raises both the bet and the RTP. Lower operator builds (~94%) and buy-RTPs are database-sourced.)
- High volatility — long dry spells; not a bankroll-preserver despite the RTP
- Feature-buy is unavailable to UK players

Our verdict on Book of Shadows
Skip if: your casino only offers a lower-RTP build of this game
Book of Shadows is Nolimit City's gothic-horror take on the Book genre, a 5-reel game where the player selects 3, 4 or 5 Shadow Rows (10/15/20 lines), an expanding special symbol and Lucky Locks respins feed a 30,338x ceiling. Crucially this title is genuinely bet-dependent: choosing more Shadow Rows raises both the stake and the certified RTP — 96.01% at 3 rows (default), 96.07% at 4 rows and 96.19% at 5 rows — so the row selection is a real RTP lever, not just a cosmetic bet change (lower ~94% operator and buy builds are database-sourced). Very High (5/5) volatility is true to the studio's house style, with the big wins funded by rare expanding-symbol hits during free spins. It suits Book-slot players who want extreme variance and will deliberately play 5 rows for the best return; the Bonus Buy is blocked in the UK.
