Book of Shadows Overview
Book of Shadows is an extreme-volatility Nolimit City slot in which the player can alter the board before and after a normal spin. Shadow Rows expand the grid from 5x3 to 5x4 or 5x5, Lucky Locks hold selected reels for a priced respin, and the free-spin feature lets the player exchange rows for a different number of spins.
Released on 20 August 2020, the game uses 10, 15 or 20 paylines and advertises a maximum payout of 30,338x bet. A Golden symbol can expand during free spins, while the Book acts as Wild and Scatter. Feature Buy, a 50/50 gamble and a Wheel of Bonus may appear depending on the regulated build.
Published versions include 96.01%, 94.09% and 90.15% RTP models. Book of Shadows is an 18+ gambling product: its extensive controls offer choices about cost and presentation, not a way to predict random results.

The variable grid is not decorative. Every added row supplies five more paylines and changes the price of a spin. The feature round uses the same row system, so a reader must distinguish active rows, awarded spins and total wager rather than treating “bigger screen” as a free upgrade.

Verified Data and Source Status
| Data point | Current provider evidence | Other verified configuration | Editorial treatment |
|---|---|---|---|
| Base RTP | 96.01% | DX1 94.09%; DX3 90.15% | The loaded help screen controls |
| Volatility | Extreme (10) | Current market review says high | Use the provider’s stronger label |
| Hit frequency | Product page 33.33% | Game sheet 33.18% simulated | Preserve methodology/date difference |
| Free-spin frequency | 1 in 154 | Game sheet also says bonus round 1 in 154 | Long-run model, not a schedule |
| 100× win frequency | Not shown on current card | Game sheet: 1 in 843 simulated spins | Applies to the documented simulation/build |
| Bet range | Current card €1–€100 | Sheet €0.10–€100 or €200 boosted | Configuration conflict; not universal |
| Maximum payout | 30,338× | Rules call it a simulated maximum | Ceiling, not an expected result |
The provider’s affiliate sheet is particularly detailed: it identifies the three game IDs, HTML5 delivery, mobile/desktop support, 19 languages and more than 100 currencies. An English operator rules file then adds row-mode RTPs, Lucky Locks conditions, free-spin ranges and gamble limits. Together they are stronger than a generic review.
The official display is not perfectly static. Its current 33.33% hit-frequency card differs slightly from the 33.18% simulated sheet, and its €1 minimum conflicts with the sheet’s €0.10. These small differences are a reason to date data and inspect the exact loaded version, not to average the figures.
Book of Shadows guide
Theme, Graphics and Design
Book of Shadows leaves Ancient Egypt behind for an occult forest. Fog, bare trees, candles and ritual marks surround the reel frame, while jars, ravens, cats, mystical objects and a dark central character populate the paytable. The Book looks like a forbidden grimoire rather than a golden tomb relic.
Adding a fourth or fifth row causes the reel area to rise into the shadowed space above it. Locks appear on individual reels after a spin, making the extra decision legible without replacing the grid with a separate screen. Golden-symbol expansions use brighter colouring so the feature result can be followed across several active rows.
The grim art and sound are unusually cohesive for a book-style slot. They remain presentation only: a whisper, flicker or near line of Books does not reveal the next random outcome.
Book of Shadows guide
Rules and Win Structure
Regular combinations pay from left to right along an active payline. Coinciding wins on different combinations are paid, and a Wild substitutes into the highest valid combination according to the paytable. The number of lines depends on the board: three rows use ten, four use fifteen and five use twenty.
Changing rows changes both coverage and the displayed wager. The rules describe each added row as an additional cost of a spin. That wording should be understood through the dynamic total shown by the interface; it is not permission to calculate an assumed universal multiplier from a screenshot.
Different reel configurations can apply in the main game and bonus modes. All payouts should therefore be checked against the active paytable, selected row count and total bet. Multiple choices do not remove the house edge.
Book of Shadows guide
Shadow Rows Base-Game Mechanic
Shadow Rows lets the player activate three, four or five rows before a normal spin. Clicking the upper part of the reel frame adds a row and five paylines. The expanded 5x4 or 5x5 area offers more visible symbol positions, but the price rises at the same time.
In the examined 96.01% rules build, four-row play is listed at 96.07% and five-row play at 96.19%. A regulated 94.09% build instead lists 94.30% and 94.42%. These mode figures are specific to their respective math packages; they should not be moved between versions.
More rows can create more frequent winning combinations and a larger display, but they do not guarantee that the extra return covers the higher cost in a session. The total bet shown before Spin is the meaningful exposure figure.
Book of Shadows guide
Free Spins and the Golden Expanding Symbol
Three or more Book symbols trigger free spins. The initial award represents 10 spins at the row count active when the feature was won. Before the round, the game randomly selects one regular Golden symbol and permits one redraw. During each spin, that symbol expands across all active positions on its reel when doing so creates additional paytable wins.
The player can change the row count before beginning, but the number of free spins changes in exchange. Official rules give ranges based on the trigger setup: a three-row trigger can result in 6–10 spins, four rows in 8–12, and five rows in 10–14. Keeping the trigger row count produces the original 10. More rows means fewer spins; fewer rows means more.
Three or more Books during free spins retrigger the feature. The rules do not support a promise of regular retriggers. They also state that free-spin entry clears any pending Lucky Locks alterations.
Book of Shadows guide
Book Wild and Scatter
Every Book of Shadows symbol acts as a Wild and substitutes for regular symbols to form the highest valid paytable combination. The same image is the Scatter: three or more Books anywhere start free spins, and the symbol can retrigger the feature during the bonus.
Lucky Locks may be used to hold Book Scatters while other reels respin, but the rules allow no more than two Scatters to be locked. This restriction prevents a player from freezing a completed three-Book trigger and repeatedly extending it.
The Golden symbol selected for free spins is separate from the Book. It does not acquire the Book’s Scatter role; it expands only under the feature’s additional-win condition.
Book of Shadows guide
Lucky Locks and Gamble Choices
After a main-game spin, Lucky Locks can hold chosen reels while the others respin for an adjusted price. Up to four reels may be locked, but impossible-to-win states cannot be held, and no more than two Scatter reels may be locked. The cost appears beside each lock, so every proposed combination should be reviewed before confirming.
Changing the bet, entering free spins or using Feature Buy clears the locks. The 96.01 rules build lists Lucky Locks at 96.10% and states that locking two Scatters is the optimal return configuration. That is a mathematical instruction for the documented mode, not a guarantee that the third Book will land or that the respin will be profitable.
Eligible wins can also enter a 50/50 colour gamble for double or nothing, limited to five consecutive attempts. The Wheel of Bonus risks a win for a chance to enter free spins and is available only under stated conditions, including a win no higher than 60x bet and no active Lucky Locks in the examined rules.
Book of Shadows guide
Payouts, Rows and Bet Examples
| Triggering setup | Active paylines at trigger | Free spins if rows stay unchanged | Official range if bonus rows change |
|---|---|---|---|
| 3 Shadow Rows | 10 | 10 | 6–10 |
| 4 Shadow Rows | 15 | 10 | 8–12 |
| 5 Shadow Rows | 20 | 10 | 10–14 |
The table does not mean a five-row trigger always awards 14 spins. It awards 10 if the player keeps five rows; a higher spin count belongs to choosing fewer rows for the feature. Conversely, moving from a three-row trigger to a larger bonus board reduces the number from 10.
For a simple spending example, suppose the interface displays 1.00 for a three-row spin and 1.50 after a fourth row is added. The second choice spends 50% more in that operator build. The actual screen, not this illustration, must provide the price because currencies, boosted-bet settings and configurations vary.
The current provider page shows €1–€100, while its game sheet shows €0.10–€100 and up to €200 with boosted bet. These are source-specific limits. The 30,338x maximum is expressed against bet, but a player should check which displayed bet basis the live rules apply.
Book of Shadows guide
Mobile Play and Controls
Nolimit City lists Book of Shadows as an HTML5 game for mobile and desktop, optimised around a 1280x720, 16:9 presentation. Responsive delivery can reorganise controls on a phone while preserving the same active mathematical build.
Touch controls allow row changes, reel locks, bet adjustment, Spin and access to information. Because Lucky Locks prices appear beside small lock icons, a phone user should pause to verify the adjusted total before confirming. Landscape mode may make the full 5x5 board and payline markers easier to read.
Autoplay, where offered, collects wins automatically and can move through wagers faster. Neither autoplay nor quick presentation changes RTP. A demo is useful for learning where Shadow Rows and locks are located, but its outcomes cannot establish a future bonus frequency.

RTP, Volatility and Maximum-Win Analysis
How the 96.01%, 94.09% and 90.15% Builds Differ
Nolimit City identifies three base models: 96.01%, DX1 at 94.09% and DX3 at 90.15%. The same interface can therefore represent materially different house edges. Row modes, Lucky Locks and Feature Buy also carry build-specific RTP values, so one isolated percentage cannot describe every possible route.
RTP is a theoretical long-run return, not a session forecast. A 96.01% label does not mean a player receives 96.01 units back from 100 units wagered, and the 90.15% version can still produce a large isolated result. All else equal, the higher configuration has the smaller mathematical house edge.
What Extreme Volatility and Frequency Figures Mean
The provider rates volatility Extreme at level 10. That is stronger wording than the “high” label used by a current market review. The practical warning is that results can be heavily uneven and the balance may decline through long periods without a substantial recovery.
The current product card shows 33.33% hit frequency, while the affiliate sheet reports 33.18% from simulation. The same sheet models a bonus round at 1 in 154 spins and a 100x-or-greater result at 1 in 843. These are long-run figures for documented builds, not timers. Passing 154 spins without a bonus does not make one due.
Understanding the 30,338x Maximum
Provider material publishes a maximum payout of 30,338x bet. The rules describe it as the maximum observed in a ten-billion-round simulation, which is not the same as declaring an exact one-in-ten-billion probability. No official max-win probability is supplied on the current product card.
At a 0.20 bet, the multiplier corresponds to 6,067.60 in the same denomination before operator limits. That arithmetic does not estimate likelihood. Gamble caps, stake limits and local maximum-payout conditions may also affect how a build presents awards.

Responsible play
How to Play Responsibly
Set a fixed loss limit and time limit before starting, and use only money reserved for entertainment. Never use funds needed for housing, food, bills or repayments. Stop at the planned limit instead of adding money after an extreme-volatility downswing.
Read the adjusted total every time Shadow Rows or Lucky Locks changes. A familiar base denomination can hide a much larger cost when extra rows, held reels or boosted bets are active. Treat Feature Buy and the Wheel of Bonus as separate high-cost decisions, not shortcuts to profit.
Avoid chasing a third Book after locking two Scatters. The provider’s optimal-return instruction does not guarantee a trigger. Use autoplay limits, time-outs, deposit controls and self-exclusion where needed. If gambling becomes difficult to stop, contact a recognised support service. Play only at 18+ and where lawful.

Editorial Verdict
Book of Shadows is one of the more purposeful variations on the book-slot formula. Shadow Rows alter the board and line count, Lucky Locks turn selected reels into a priced decision, and the bonus lets the player trade rows against spins before a Golden image begins expanding. The occult design supports those mechanics rather than merely reskinning them.
Its flexibility demands careful reading. Three RTP builds, mode-specific returns, two official minimum-bet displays and conditional gamble tools make a single specification card insufficient. For players comfortable with extreme volatility, it is a mechanically rich slot; for everyone else, the most important feature is the information screen showing the actual build and total cost.

Frequently Asked Questions
What is the RTP of Book of Shadows?
Nolimit City lists 96.01%, 94.09% DX1 and 90.15% DX3 builds. Row modes and optional features can have separate values. Confirm the exact percentage in the loaded game.
How many rows and paylines are available?
Three rows use 10 paylines, four rows use 15 and five rows use 20. Each added row raises the displayed price of a spin.
How are free spins triggered?
Three or more Book Wild/Scatters anywhere trigger the feature. Keeping the same row count provides 10 spins; changing rows alters the award.
Why can free spins range from 6 to 14?
The range depends on the row count that triggered the bonus and the row count chosen for the feature. More rows exchange spins for a larger grid; fewer rows exchange grid size for more spins.
What does the Golden symbol do?
One regular symbol is chosen randomly and may be redrawn once. It expands over the active positions on its reel when expansion creates additional paytable wins.
How do Lucky Locks work?
After a main-game spin, eligible reels can be held while the others respin for an adjusted price. Up to four reels but no more than two Scatter reels may be locked.
Can the bonus be purchased?
Nolimit Bonus may provide direct free-spin access. The provider states that Feature Buy and gamble-to-bonus can be removed in regulated markets, so availability is not universal.
What is the maximum payout?
Provider material states 30,338x bet. Rules describe it as a simulated maximum from ten billion rounds, not an exact published probability of one in ten billion.
Is the hit frequency exactly 33.33%?
The current provider card shows 33.33%, while its game sheet reports 33.18% simulated. The difference likely reflects display methodology or source version; neither predicts when the next win will occur.

Player Reviews
No verified player testimonials, win screenshots or session records were supplied for this page. Future submissions should be labelled as user contributions, moderated for personal information, affiliate promotion and unsupported claims, and kept distinct from the verified game specification.
A comment that Lucky Locks “always” finds the third Book or that a bonus appeared after a set number of spins is anecdotal and mathematically misleading. Useful feedback can cover mobile readability, whether adjusted prices were clear and which rules build was displayed, without sharing account identifiers, payment information or other private data.
