Book of Power is a Relax Gaming pokie with an Egyptian book setup, 10 fixed paylines and two Free Spins paths. The regular feature focuses on expanding symbols, while Power Free Spins add upgrades and golden reels. We checked the rules, paytable and bet tools because the extra options matter here more than the base game.

Game Overview
Book of Power is a 5-reel, 3-row Relax Gaming slot with 10 fixed paylines and a high-volatility profile. The theme is classic Egyptian treasure hunting, but the feature design is busier than a plain book slot. Blue Book symbols work as Wilds and Scatters, opening regular Free Spins with a randomly selected expanding symbol. The red Power Book matters when Power Bet is active, because it can unlock Power Free Spins and golden reels. We checked the reviewed version at 96.11% RTP and a max win of 15,000x the total bet. The base game is easy to understand, but the real value sits in the bonus structure, especially retriggers, expanding-symbol upgrades, Power Bet and the two Bonus Buy options.
Game Features & Mechanics
-
Fixed Line Setup
The game uses 10 fixed paylines across the 5x3 grid. Regular wins pay from left to right on selected lines.
-
Scatter Awards
Landing 3, 4 or 5 Book symbols triggers 10, 15 or 20 Free Spins. The same counts also award scatter payouts.
-
Retrigger Books
During Free Spins, 2 Book symbols award 5 extra spins. They can add another expanding symbol or improve an existing one.
-
Max Win Limit
The maximum win is 15,000x the total bet. Once that ceiling is reached, the game pays the win and ends the round.
Technical Specifications
-
Volatility Level
Book of Power is a high-volatility pokie. The bonus features can hit hard, but quiet base-game stretches are part of the setup.
-
RTP Explained
The checked version uses 96.11% RTP. Feature Buy modes can show 96.50%, while some operator versions may run lower RTP settings.
-
Bet Range
The official listed range runs from $0.10 to $60 per spin. Casino settings can affect the available stake levels, so the exact range may not look identical everywhere.
Paytable & Symbol Values
Book of Power uses card ranks and Egyptian relic symbols for regular line wins. The Explorer is the strongest standard symbol, paying 1x, 10x, 100x and 500x for 2, 3, 4 or 5 on a payline. The Death Mask follows with 0.5x, 4x, 40x and 200x. The Pyramid and Scarab Chest both pay 0.5x, 3x, 10x and 75x. Lower symbols are A, K, Q, J and 10. A and K pay 0.5x, 4x and 15x for 3, 4 or 5, while Q, J and 10 pay 0.5x, 2.5x and 10x. Regular wins start from the leftmost reel and pay across the 10 fixed paylines.
Special Symbols
Blue Book
The Blue Book works as a Wild and Scatter. It pays 1x, 10x, 100x and 500x for 2, 3, 4 or 5 symbols.
Power Book
The Power Book is the red book symbol. It carries the same 1x to 500x pay range and is tied to the stronger bonus route.
Expanding Symbol
At the start of Free Spins, a random symbol is selected as the Expanding Symbol. When it lands during the feature, it can expand and pay across all 10 paylines according to its paytable value.
Graphics, Animations & Sound Design
-
Graphics
Book of Power uses a polished temple setting with stone reels, Egyptian relics, gold details and an explorer as the top regular symbol. The style is darker than many old book slots, but the pay symbols stay clear. We found the blue and red books easy to separate during play.
-
Animations
Base-game movement is restrained, with most visual action saved for books, expanding symbols and golden reel changes. Free Spins show symbols expanding cleanly across the reels instead of covering the screen with effects. Power Free Spins feel sharper because gold reels remain visible between spins.
-
Sound Design
The sound uses dramatic Egyptian-style music, reel effects and stronger hits around books and bonus entry. It suits the treasure-hunt theme without making the rules harder to follow. The important information still comes from symbol positions, reel colour and the feature meter beside the grid.
-
Visual Feel & Interactivity
The game feels calm in base spins and much busier once Free Spins begin. Expanding symbols, special symbol meters and golden reels give the screen more to track. It is still readable, but Power Free Spins need more attention than a basic book-slot bonus.

Book of Power on Mobile Devices and Other Platforms
Book of Power works well on mobile because the reel grid is simple, but the feature information needs enough space. During Free Spins, the chosen expanding symbol, active upgrades, book symbols and golden reels all matter at the same time. We found the base game easy on phones, while Power Free Spins are clearer on tablet or desktop. Smaller screens can still handle the game, but the side meter and reel colour changes are easier to read when the display is not cramped. Feature Buy and Power Bet controls also need a quick check before play, especially if you are adjusting stakes between regular spins and boosted spins.
-
Android
Android play works fine on current devices. Larger phones help when checking the expanding-symbol meter and book positions during Free Spins.
-
iOS
iOS keeps Book of Power smooth and simple to control. Bigger iPhone screens make golden reels and feature counters easier to read.
-
Tablet
Tablet gives the best mobile view. The reels, side meter, book symbols and bet controls have more room without stretching the layout.
-
Desktop
Desktop is the clearest option for longer sessions. Paytable values, Power Bet settings and Feature Buy prices are easier to check.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialFree Spins and Power Free Spins can include retriggers, upgrades and reel changes. A stable connection helps those sequences complete without interruption.
-
Landscape Mode Recommended
RecommendedLandscape mode gives the reels more width and helps separate the blue book, red book, selected symbol and golden reels.
-
Audio Settings
OptionalSound supports the temple theme and bonus moments, but the game remains readable through symbols, paytable panels and reel changes.
-
Full Screen Mode
RecommendedFull screen is useful here because the feature meter matters. It also makes paytable checks and Power Bet settings easier to read.

About Relax Gaming — The Developer Behind the Game
Relax Gaming is a B2B iGaming provider and aggregator known for online casino content, partner distribution and in-house slot development. Its portfolio includes proprietary games, third-party aggregation and supporting tools for operators. The company is also connected with several regulated jurisdictions, including Great Britain licensing, which matters when casinos need supplier content that can fit stricter market requirements.
The provider’s slot style is usually more experimental than purely traditional. Relax often takes a familiar base idea, then adds a sharper feature layer around it. That can mean high-volatility bonus rounds, unusual multipliers, feature buys, special reel states or mechanics that make the bonus feel different from the base game. We usually expect Relax titles to explain their core rules clearly, but still reward players who read the details before playing. Book of Power follows that pattern well: the grid is simple, but the Power Bet, Power Free Spins and golden reels need proper attention.
-
Aggregation Network
Relax Gaming works as both a studio and aggregator, giving operators access to in-house titles and selected partner games.
-
Licensed Supply
The provider operates with licensing across regulated markets, which helps casinos source games under stricter compliance requirements.
-
Experimental Features
Relax slots often take familiar themes and add sharper bonus mechanics, higher volatility or unusual feature structures.
Final Verdict
Why It’s Worth Playing
- Power Free Spins give the slot a stronger bonus route than a standard expanding-symbol book game
- Golden reels make the middle reels more important once Power Books start changing the feature screen
- Symbol upgrades can improve the selected expanding symbol, so the bonus is not locked to its first pick
- Power Bet gives a clearer route towards stronger features, although the spin cost doubles while active
- The 15,000x max win gives Book of Power a much higher ceiling than many simple Egyptian pokies
Things to Consider
- High volatility can make the base game feel dry, especially when the feature does not trigger for longer stretches
- Power Bet doubles the spin cost, so it needs tighter budget control than standard base-game spins
- The feature rules are more detailed than a basic book slot, so checking the paytable first really matters
Overall Rating
8.6
Bottom Line
Book of Power works best as a high-volatility book slot for players who want more than one expanding-symbol route. The regular Free Spins are familiar enough, but Power Free Spins, golden reels and symbol upgrades give the game its stronger identity. We like that the base grid stays simple while the feature design carries the depth. The trade-off is cost and volatility. Power Bet and Feature Buy can make play more expensive, and the best outcomes sit behind bonus action. It is a better fit for patient players than for quick, low-risk sessions.
