Book of Cats Slot Review: Rules, Features and Conflicting Game Data Explained
Book of Cats is a BGaming video slot that reshapes Ancient Egyptian imagery around stylised felines. Its 6×3 framework gives the sixth reel a special role in longer base-game wins and free-spin expansions.
Released on 8 July 2020 under game ID `BookOfCats`, it has ten fixed paylines, a Golden Book Wild/Scatter and an optional Gamble round. Published RTP, volatility, maximum-win and bet figures conflict, so this review keeps each data set visible.
Book of Cats is an 18+ gambling product. A demo, where legally available, uses virtual credits and cannot provide withdrawable winnings. Real-money play can lose the full amount staked, and no feature described below creates a predictable outcome.

Book of Cats Overview
| Category | Editorial overview |
|---|---|
| Provider | BGaming |
| Official game ID | `BookOfCats` |
| Release date | 8 July 2020 |
| Framework | 6 reels × 3 rows, with a special sixth reel |
| Paylines | 10 fixed lines |
| Direction | Left to right on consecutive reels in the base game |
| Core features | Winline Expanding, free spins, selected expanding symbol, Golden Book Wild/Scatter, Gamble |
| Optional tools | Buy Bonus, Auto Mode and Quick Spin where the operator’s licence allows them |
| Devices | Optimised for smartphones and desktop according to the provider |
| Randomness | Provider states that a certified RNG is used |
The first five reels form the normal base-game area. Two cells on reel six are covered, leaving one visible symbol that can extend a qualifying five-reel result through Winline Expanding. The clearest description is therefore a 6×3 framework with a special sixth reel.

Verified Data and Source Status
| Data point | Current provider page | Older or supplied material | Editorial treatment |
|---|---|---|---|
| RTP | 96.99% | 94% | Configuration conflict; verify in-game |
| Volatility | Very high | Medium-high | Current label prioritised, older label retained |
| Maximum multiplier | 8,202× | 10,000× | Do not present either as universal |
| Maximum win | €246,060 | Not stated in the supplied review | Current page figure, subject to version and stake |
| Bet range | Not resolved in live template | 0.20–50 | Treat as one source configuration |
| Hit Rate field | 2.78 | Not provided | Unit is not defined on the visible product page |
| FS Rate field | 140 | Not provided | Unit is not defined on the visible product page |
The live rules template uses `{RTP.main}`, `{RTP.bonus_buy}`, `{min_bet}` and `{max_bet}` rather than universal figures. Operator builds can therefore inject configuration data, making the in-game help screen the controlling reference.
The units for Hit Rate 2.78 and FS Rate 140 are not defined publicly. Do not convert them into a percentage or a fixed “one bonus per 140 spins” claim without version-specific rules.

Theme, Graphics and Design
Book of Cats makes felines the visual leads of its Egyptian setting. The paytable includes a green pharaonic cat, a supernatural-looking purple cat and an Ankh-themed cat. A human Pharaoh remains the highest-paying regular image in the supplied examples.
Lower A, K, Q, J and 10 symbols also carry feline details, while the Golden Book preserves the familiar book-slot connection.
Nile scenery, palms and desert tones frame the grid, accompanied by restrained music. The clean presentation keeps reel six readable. Graphics and sound are aesthetic only and never signal a pending win.
Book of Cats guide
Rules and Fixed Paylines
Book of Cats uses ten fixed paylines. In the base game, ordinary line wins begin on the leftmost reel and continue across consecutive reels. If more than one payline wins on the same spin, the qualifying amounts are added. Where multiple combinations could be evaluated on one line, only the highest line win is paid according to the official rules.
The player cannot reduce the ten lines. Changing total bet scales the stake across that fixed structure, so check the full displayed amount. A larger bet raises exposure and cash payouts but does not create an exploitable result pattern.
The Golden Book has separate Scatter rules, so its wins do not need to follow the same consecutive-line logic. Scatter prizes are calculated from total bet and can be paid alongside ordinary line wins. Exact multipliers must be read from the paytable of the active configuration.
Book of Cats guide
Winline Expanding Feature
During a standard spin, the first five reels work normally while the sixth shows only one uncovered cell. Suppose a symbol creates a qualifying line combination across the first five reels and the same symbol appears in that visible sixth position. The sixth-reel image then expands over all three cells, allowing the game to complete the longer combination according to the relevant payline.
That is why six-symbol awards exist despite the five-reel appearance. Reel six responds to a matching-symbol rule; a near miss does not make a later match more likely.
Book of Cats guide
Free Spins and the Expanding Symbol
Three or more Golden Books trigger 10 free spins. At the moment the bonus is awarded, the regular symbol visible in the sixth-reel cell becomes the selected expanding symbol. The Golden Book itself cannot be chosen. During the feature, the sixth reel is fully unlocked rather than mostly covered.
Ordinary payouts are evaluated first. The chosen symbol can then expand and pay on the ten lines from non-adjacent positions when enough matches appear, unlike conventional base-game combinations. The loaded rules define the exact threshold.
Three more Books retrigger the feature. Current rules state no hard retrigger cap, but repeated bonuses are never guaranteed.
Book of Cats guide
Golden Book Wild and Scatter
The Golden Book substitutes for regular pay symbols when it functions as Wild. It can help complete line combinations, subject to the exclusions and evaluation rules in the active paytable. As Scatter, three or more Books start the ten-spin feature and may produce a Scatter payout based on total bet.
Scatter and line wins can pay together. The Book cannot become the selected expanding symbol; Wild substitution, Scatter payment and bonus expansion remain separate calculations.
Book of Cats guide
Gamble Feature
After an eligible base-game win, Book of Cats may offer a card-based Gamble round. Guessing the card colour correctly pays 2× the amount risked. Identifying the exact suit correctly pays 4×. A wrong selection loses the amount committed to the feature. Gamble does not change the reel outcome or provide a long-term player advantage.
Gamble remains available only while the win is below one quarter of the maximum limit and the next outcome cannot exceed the cap. Licensing may remove it. Declining preserves the eligible win.
Book of Cats guide
Buy Bonus and Licence Restrictions
Where permitted, Buy Bonus lets the player purchase immediate entry to the free-spin round. Its price scales with the selected total bet. Paying for access does not guarantee that the resulting ten spins return more than their purchase cost, and the bonus RTP may be configured separately from the main-game RTP.
Licensing can disable Buy Bonus, Auto Mode and Quick Spin. Their absence is not necessarily a fault; use only controls supplied by a lawful local operator.
Book of Cats guide
Payouts and Bet Examples
The following multipliers come from the supplied paytable summary. They are retained as source examples and must be checked inside the active game, particularly because the current maximum-multiplier claim differs from the older one.
| Six-symbol line | Source payout example |
|---|---|
| Pharaoh | 7,500× |
| Green cat | 2,500× |
| Purple cat | 1,000× |
| Ankh cat | 1,000× |
| Golden Book | 400× |
| A, K or Q | 375× |
| J or 10 | 250× |
The supplied review gives a 0.20–50 stake range, without specifying currency. Live rules use bet placeholders, so this is one configuration example. Let the interface calculate multiplier payouts against the applicable bet basis.
Raising total bet from 0.20 to 1.00 multiplies exposure and cash payout values by five, not the probability of a symbol result. Do not reverse-engineer 8,202× and €246,060 into a universal stake cap.
Book of Cats guide
Mobile Play and Controls
The provider lists smartphone and desktop optimisation. Screen layout can vary, but an identical certified version should retain the same mathematics.
Controls include total-bet adjustment, Spin, sound and a desktop spacebar shortcut. Licensed builds may add Autospins and Quick Spin. Faster play changes wagering pace, not outcomes.
Before paid play, confirm RTP, bet limits, paytable and feature availability. Demo outcomes contain no information about later spins.

RTP, Volatility and Maximum-Win Conflicts
Why RTP Appears as 94% and 96.99%
The supplied editorial source and the archived rules dated 26 May 2020 state 94% RTP. The current BGaming product page displays 96.99%. Meanwhile, the live rules template contains separate placeholders for the main game and bonus-buy RTP. The most plausible editorial explanation is configuration by operator, market or game mode, but that should be presented as a possibility rather than proven history. The in-game value at the selected licensed operator controls.
RTP is a statistical long-run model, not a refund. Neither 94% nor 96.99% predicts what one person will receive in a session. A higher listed configuration is mathematically preferable all else being equal, yet short-term loss remains possible.
Medium-high or Very High Volatility?
The older review calls volatility medium-high. The current provider page labels it very high. This guide prioritises the current provider label while preserving the older description. The difference could reflect changed classification, configuration or editorial judgement. Volatility categories are not perfectly standardised across publishers, so bankroll guidance should focus on the practical point: returns can be uneven and long gaps between notable wins are possible.
10,000×, 8,202× or €246,060?
The supplied source and a 2022 provider marketing item refer to 10,000×. The current product page shows 8,202× and a maximum win of €246,060. These values may relate to different releases, caps or stake configurations. There is not enough public information in the live template to declare one universal number. A responsible page should display the current provider figures, retain the older claim as historical context, and direct readers to the live paytable.

How to Play Responsibly
Decide on a loss limit and time limit before pressing Spin. Use money reserved for entertainment, never funds needed for housing, food, bills or debt payments. A free-spin trigger, an exposed matching symbol on reel six or a long losing run does not make a future win due. Do not raise the stake in an attempt to recover previous losses.
Buy Bonus deserves separate budgeting because one purchase can cost many base-game spins. Compare the price with the full session limit before confirming. Gamble can erase an existing win immediately; decline it whenever losing that amount would cause frustration or exceed the plan. Autospins and Quick Spin can accelerate spending, so use available stop conditions and review the balance frequently.
If gambling begins to feel difficult to control, stop playing. Use deposit limits, time-outs and self-exclusion tools, and contact a specialist support organisation. Book of Cats is for adults aged 18 or over and only in jurisdictions where the operator and game are authorised.

Editorial Verdict
Book of Cats earns its identity through more than cat artwork. The restricted sixth reel gives the base game a clear visual question on every spin, while the unlocked bonus reel and selected expanding symbol change how free-spin wins are evaluated. The Golden Book ties the structure together without overwhelming the interface with unrelated features.
Its data presentation is less tidy. A visitor can encounter two RTP values, two volatility labels and three ways of describing the maximum return. Those conflicts do not make the mechanics unknowable, but they make version checking essential. The best description is therefore conditional: Book of Cats is a distinctive, very-high-volatility slot in its current provider listing, with specifications that must be confirmed in the exact licensed build before play.

Frequently Asked Questions
What is the RTP of Book of Cats?
The archived 2020 rules and supplied review state 94%, while the current provider page shows 96.99%. Live rules use configuration placeholders. Check the in-game help screen at the selected licensed operator for the controlling value.
Is Book of Cats a 5×3 or 6×3 slot?
It is best described as a 6×3 framework with a special sixth reel. In the base game only one cell of that reel is visible, so the first five reels form the ordinary win area. The sixth can expand for qualifying wins and becomes fully available in free spins.
How many paylines are there?
There are ten fixed paylines. Base-game line wins run left to right on consecutive reels, while Scatter and selected-symbol rules are evaluated separately.
How are free spins triggered?
Three or more Golden Books award ten free spins. The regular symbol visible in the sixth-reel cell becomes the selected expanding symbol; the Book cannot be selected. Three or more Books during the feature retrigger the round, with no hard retrigger limit stated in the current rules.
What does Winline Expanding do?
If a qualifying symbol win appears across the first five reels and the same symbol is visible on reel six, that sixth-reel image expands over its three positions and completes the longer line result according to the paytable.
What is the maximum win?
The current provider page displays 8,202× and €246,060. Older material cites 10,000×. These should be treated as version- or configuration-dependent until the active help screen confirms the applicable cap.
Can the free spins be purchased?
Buy Bonus may be available and its price scales with total bet. Licensing rules can remove it, and the purchased feature does not guarantee a return greater than its cost.
Does Gamble improve the RTP?
It offers a 2× result for a correct colour or 4× for a correct suit, while an incorrect guess loses the risked win. It is optional and should not be treated as a strategy for overcoming the house edge.
Is Book of Cats Megaways the same game?
No. Book of Cats Megaways is a separate later title. Its reel system, mathematics and product figures should not be mixed with the original Book of Cats reviewed here.

Player Reviews
No real-player testimonials or claimed wins are supplied for this page. Any future review must be labelled as a user contribution, moderated for personal data and promotional links, and kept separate from verified game facts. A comment about a large win, bonus frequency or withdrawal speed is anecdotal and cannot establish RTP, fairness or likely outcomes for another player.
The review area should invite readers to discuss interface clarity, mobile usability and whether the rules were easy to locate, while reminding them not to publish account numbers, payment details or identifying information. Editorial ratings should disclose their methodology and must not be presented as evidence that the slot will pay.
