Book of Power is a high-volatility Egyptian-themed slot developed by Relax Gaming in collaboration with Casinogrounds. The game features dual book symbols, expanding symbols, and an innovative Power Bet mechanic that enhances bonus trigger rates by 170%.
Book of Power represents Relax Gaming's collaboration with Casinogrounds to deliver a sophisticated take on the Egyptian book slot genre. While the theme follows familiar territory, the execution combines polished visuals with mechanical innovations that distinguish it from standard book slots. The game targets experienced players seeking high-volatility action with strategic betting options that directly influence bonus frequency and potential.
The visual design of Book of Power strikes a balance between classic Egyptian aesthetics and modern graphical fidelity. Unlike older book slots that rely heavily on stylized artwork, this release incorporates realistic background imagery reminiscent of Push Gaming's Mystery Museum. The game grid sits against detailed temple architecture, while symbols feature crisp rendering that maintains clarity across different screen sizes.
The interface provides clear numerical indicators for all game parameters, making it accessible for both newcomers to the genre and veterans. The overall presentation avoids excessive animation that can distract from gameplay, instead focusing on smooth reel mechanics and clear win presentations. This design philosophy ensures the game remains functional during extended sessions without visual fatigue.
Book of Power utilizes a straightforward 5-reel, 3-row configuration with 10 fixed paylines. Winning combinations form from left to right, requiring at least three matching symbols on adjacent reels starting from the leftmost position. The paytable divides into low-value card royals and high-value thematic symbols, with the explorer character serving as the premium symbol at 500x stake for a five-of-a-kind combination.
The low-paying symbols consist of five card ranks from 10 through Ace, each rendered with ornate Egyptian styling. These symbols deliver payouts ranging from 10x to 15x stake for five matching symbols. The premium tier includes three Egyptian-themed symbols plus the explorer, with payouts scaling from 75x to 500x stake for maximum combinations.
Both Book symbols function as wilds, substituting for all regular pay symbols to complete winning combinations. This dual-wild system increases hit frequency during base game play while serving the critical role of scatter symbols for bonus activation. The distinction between regular and Power Books becomes significant only when the Power Bet feature is engaged.
The Power Bet represents the game's primary strategic element. Activating this feature doubles the base stake but provides two substantial benefits. First, it increases the probability of triggering any free spins feature by 170%, significantly improving bonus frequency. Second, it enables access to Power Free Spins through a gamble feature when regular free spins are awarded.
This mechanic creates a meaningful decision point for players. Those prioritizing bonus frequency and willing to accept higher per-spin costs will find the Power Bet mathematically favorable over extended sessions. Conservative players can opt for standard betting, accepting lower bonus frequency in exchange for reduced volatility and extended playtime per bankroll unit.
Landing three, four, or five Book symbols anywhere on the reels triggers the free spins feature, awarding 10, 15, or 20 spins respectively. The trigger also delivers immediate payouts of 10x, 100x, or 500x stake based on the number of scatters, providing instant value before the bonus round begins.
At the start of free spins, the game randomly selects one pay symbol to serve as the special expanding symbol for the duration of the feature. This selection occurs through an animated book-opening sequence that builds anticipation. The chosen symbol gains the ability to expand across entire reels when winning combinations are possible, fundamentally changing the payout structure.
During free spins, the special expanding symbol operates under different rules than base game symbols. When enough expanding symbols land to form a win, they first pay according to standard payline rules. Then, they expand to fill their respective reels completely and pay as scatter symbols, requiring only that sufficient symbols appear anywhere on the reels rather than on specific paylines.
This mechanic dramatically increases win potential, particularly when high-value symbols are selected as the expanding symbol. A screen filled with expanded premium symbols can deliver wins exceeding 1000x stake. The feature can retrigger by landing additional Book symbols during free spins, with each retrigger adding spins according to the same structure as the initial trigger.
Book of Power operates on a classic 5-reel, 3-row layout with 10 fixed paylines. The game employs a traditional Egyptian book slot structure enhanced with modern mechanics. Players can activate the Power Bet feature by doubling their stake, which significantly increases bonus trigger probability and unlocks access to Power Free Spins through the gamble feature.
The mathematical model balances high volatility with competitive RTP values. The expanding symbol mechanic during free spins allows symbols to cover entire reels and pay as scatters, creating substantial win potential. Maximum win potential reaches impressive levels through the combination of expanding symbols and multiple retriggers during bonus rounds.
When playing with the Power Bet active and triggering regular free spins, players receive the option to gamble their awarded spins for a chance at Power Free Spins. This gamble feature presents a risk-reward decision: success upgrades the bonus to the enhanced version, while failure forfeits the free spins entirely.
Power Free Spins function identically to regular free spins with one critical enhancement: two symbols are selected as special expanding symbols instead of one. This doubles the potential for expanded symbol wins and significantly increases the maximum win potential of the feature. The presence of two expanding symbols creates scenarios where multiple reels fill with high-value symbols simultaneously, generating the game's largest payouts.
The gamble decision requires careful consideration of risk tolerance. Players with sufficient bankroll to absorb potential losses may find the enhanced win potential of Power Free Spins worth the risk. Conservative players can decline the gamble and accept the standard free spins, which still offer substantial win potential through the single expanding symbol mechanic.
Book of Power includes bonus buy functionality for jurisdictions where this feature is permitted. Players can purchase direct entry to either regular free spins or Power Free Spins, bypassing base game play entirely. The bonus buy RTP increases to 96.5%, slightly higher than the base game's 96.11%, reflecting the mathematical advantage of guaranteed bonus access.
The cost of bonus buys scales with the enhanced win potential. Regular free spins typically cost around 75x to 100x the base stake, while Power Free Spins command a premium price reflecting their dual expanding symbol advantage. These options suit players who prefer concentrated bonus round action over extended base game sessions.
Book of Power carries a high volatility rating, meaning wins occur less frequently but tend toward larger amounts when they hit. This volatility profile suits experienced players with adequate bankrolls to weather extended losing streaks while pursuing substantial bonus round payouts. The game's hit frequency in base play remains moderate, with small wins maintaining engagement between bonus triggers.
The RTP values demonstrate competitive positioning within the market. The base game RTP of 96.11% sits slightly above industry average, while the bonus buy RTP of 96.5% provides mathematical justification for the feature buy cost. These figures represent long-term theoretical return and should not be interpreted as guarantees for individual sessions, particularly given the high volatility profile.
Optimal play in Book of Power centers on bankroll management appropriate to the high volatility. Players should ensure their bankroll can sustain at least 100 to 150 base game spins to provide reasonable probability of triggering bonuses through natural play. The Power Bet feature, while mathematically favorable for bonus frequency, requires doubling this bankroll recommendation due to the increased per-spin cost.
Symbol selection during free spins significantly impacts potential returns. High-value symbols as expanding symbols offer the largest win potential but require fewer symbols to appear for wins to register. Low-value symbols appear more frequently but deliver smaller payouts even when expanded. The random selection process means players cannot influence this outcome, but understanding the implications helps set appropriate expectations for each bonus round.
Within the crowded Egyptian book slot category, Book of Power distinguishes itself through the Power Bet mechanic and dual book system. While games like Book of Dead and Legacy of Dead established the genre template, this release adds strategic depth through player-controlled variance adjustment. The visual presentation also exceeds many competitors, particularly older releases that have not received graphical updates.
The dual expanding symbol potential in Power Free Spins creates win scenarios unavailable in standard book slots. This feature alone justifies consideration for players familiar with the genre seeking enhanced volatility and win potential. However, the core gameplay remains recognizable to book slot veterans, ensuring accessibility despite the mechanical additions.
Book of Power successfully iterates on the Egyptian book slot formula by introducing meaningful mechanical innovations without abandoning the genre's proven appeal. The Power Bet system provides strategic depth, while the dual book mechanics and Power Free Spins variant offer enhanced win potential for players willing to accept increased risk. The high volatility profile and competitive RTP values position the game favorably for experienced players seeking substantial payout potential.
Relax Gaming's collaboration with Casinogrounds has produced a polished, feature-rich slot that respects genre conventions while pushing boundaries through thoughtful mechanical additions. Players who appreciate book slots but seek more strategic control and enhanced bonus potential will find Book of Power delivers on both fronts. The game succeeds in offering something new to a well-established category without alienating fans of traditional book slot gameplay.
Book of Power has an RTP of 96.11% for standard play with or without the Power Bet active. When using the bonus buy feature, the RTP increases to 96.5%. These values represent long-term theoretical return to player percentages.
The Power Bet doubles your stake and increases the chance of triggering free spins by 170%. It also enables the gamble feature when free spins are awarded, allowing you to risk your spins for a chance at Power Free Spins with two expanding symbols instead of one.
While the exact maximum win is not specified in available documentation, the combination of dual expanding symbols during Power Free Spins, high-value premium symbols paying 500x for five-of-a-kind, and the scatter pay mechanic creates potential for wins exceeding several thousand times stake during optimal bonus rounds.
Yes, free spins can retrigger by landing three or more Book symbols during the bonus round. Retriggers award additional spins using the same structure as the initial trigger: 10 spins for three Books, 15 for four Books, and 20 for five Books.
Book of Power is rated as high volatility, meaning wins occur less frequently but tend toward larger amounts. This volatility profile requires appropriate bankroll management and suits experienced players comfortable with significant balance fluctuations.
Book of Power uses 10 fixed paylines across its 5-reel, 3-row grid. Winning combinations form from left to right on these paylines, though expanding symbols during free spins pay as scatters regardless of payline position.
