How Book of Shadows plays
The base layout starts as a conventional line slot. Matching symbols pay from left to right, with card ranks below the themed occult premiums.
Shadow Rows can add positions above the standard grid. The taller reel set creates more room for the chosen expanding symbol during Free Spins.
Three or more book scatters award the bonus and select one regular symbol to expand. A full-reel expansion pays on all eligible lines according to the feature rules.
Nolimit City released the game on 19 August 2020. Its 5 reels × 3–6 rows layout uses 20, with variable reel height with expanding symbols. The provider does not currently offer an accessible official demo for this title.
Bonus features
Shadow Rows
Extra rows can open above the reels and increase the active grid height. Their appearance changes the number of positions, not the stake already confirmed for that spin.
Expanding symbol
One regular symbol is selected when Free Spins begin. Enough matching symbols can expand to cover their reels and create multiple line wins.
Book wild/scatter
The book substitutes for standard symbols in ordinary wins and also triggers Free Spins when at least three land anywhere in view.

The standard RTP is 96.01%. Nolimit City frequently supplies several mathematical models, so confirm the exact game build.
High volatility is typical of expanding-symbol book slots. Many bonuses may return modest line wins, while a rare full premium expansion accounts for much of the ceiling.
RTP describes a theoretical return across a very large number of rounds. It does not mean that a short session will return 96.01%. Volatility describes how unevenly results may be distributed, while the 30,338× maximum is a mathematical ceiling rather than a forecast.
Our Book of Shadows verdict
Book of Shadows adds a meaningful grid extension to a familiar book-slot formula. Shadow Rows provide more than a visual change because they alter the space available for expansions.
The design remains heavily bonus-dependent and can be unforgiving between features. It suits players who already understand expanding-symbol volatility and want a more elaborate version.
