Book Of Power

Book Of Power separates itself from the crowded book-slot category by stacking two separate Book symbols and a tiered Power Spins upgrade system on top of the familiar expanding-symbol mechanic. Relax Gaming built it on 5x3 reels with 10 paylines, high volatility, and a 15,000x maximum win. The game runs on desktop and mobile at Wild.io, where crypto deposits get you into the feature fast with the Power Bet option.

What is Book Of Power?

Book Of Power is a 5x3 video slot from Relax Gaming with a 94.0% RTP, high volatility, and a top win of 15,000x your bet. It plays on 10 paylines and carries two Book symbols, a regular Book and a Power Book, each acting as both wild and scatter.

Three or more Books landing anywhere in view award 10, 15, or 20 free spins for 3, 4, or 5 symbols respectively, alongside an upfront payout of 10x, 100x, or 500x the stake. Before free spins begin, the book opens and selects a special expanding symbol. During the bonus, that symbol needs just 2 instances anywhere in view to expand and fill entire reels, paying regardless of adjacency. Retriggers during Power Spins upgrade the expanding symbol tier by tier and attach climbing multipliers when the top Explorer tier is reached.

Book Of Power Slot Theme & Graphics

Book Of Power sets its story in an ancient world of mystical artifacts and arcane knowledge. The 5x3 reels sit against a stone chamber backdrop, with glowing manuscript pages and golden ornamental details framing the symbols. The visual palette leans into deep blues, gold, and aged parchment tones, giving the game a heavier, more dramatic feel than most Egyptian-adjacent book slots.

Character symbols are drawn with clear detail at their default size and snap into focus as expanded versions during the free spins, filling the reel with the kind of full-size artwork that makes an expanding mechanic feel satisfying. The Power Book symbol has a distinct visual treatment from the regular Book, with additional glowing effects that signal its higher scatter value. Sound design pairs a slow orchestral build for the base game with an escalating intensity during free spins that matches the retrigger progression.

Book Of Power Slot Symbols & Paytables

Book Of Power uses a dual-book symbol structure that sets it apart from standard book slots. Both book variants are wild and scatter simultaneously, while the expanding symbol changes per bonus round depending on what the opening animation selects.

Low Value Symbols

The low-value symbols are royal card ranks styled with ancient manuscript borders: A, K, Q, J, and 10. These are the most common symbols on the 10-payline grid and provide frequent baseline wins that keep the game ticking through the base game. They can also become the expanding symbol during free spins, though when a royal is selected it requires 3 instances in view rather than 2 to trigger its expansion.

High Value Symbols

The high-value symbols are thematic character and artifact designs representing mythical figures and mystical items. Among these, the top-tier Explorer symbol holds a special position: it is the pinnacle of the retrigger upgrade path in Power Spins, and reaching it attaches multipliers that climb further with each subsequent retrigger. Landing the Explorer as the expanding symbol and then retriggering to increase its multiplier is the primary route to the 15,000x maximum win.

Special Symbols

The regular Book and the Power Book each function as both wild and scatter. As wilds, they substitute for all paying symbols on the 10 paylines. As scatters, landing 3 of either or any combination awards free spins: 3 symbols give 10 spins and a 10x upfront payout, 4 give 15 spins and 100x, and 5 give 20 spins plus 500x. The presence of two book variants doubles the frequency of scatter hits compared to a single-book title. During free spins, the book opens to select the special expanding symbol; this expands across entire reels whenever 2 or more instances appear anywhere in view, with royal symbols requiring 3 to trigger expansion.

Book Of Power Bonus Feature & Special Features

Free Spins with Expanding Symbol

Landing 3, 4, or 5 Book symbols anywhere in view triggers the main free spins feature, awarding 10, 15, or 20 spins along with an immediate cash payout of 10x, 100x, or 500x the stake. Before the round begins, a book-opening animation selects one symbol to gain expanding powers for the entire session. During free spins, any spin where that selected symbol appears at least twice on the reels causes it to expand and fill every position on those reels, creating full-reel wins that pay across all 10 paylines regardless of symbol adjacency. A character symbol needs 2 instances anywhere in view to expand; a royal card symbol requires 3. The expanding behavior is fixed for the entire bonus round, so the feature outcome depends substantially on which symbol is chosen at the start.

Power Spins Retrigger and Multiplier Upgrade

When 3 or more Book scatters land during the base free spins round, a retrigger is awarded and the Power Spins system activates. Each retrigger either adds an extra expanding symbol to the round or upgrades the current expanding symbol to the next tier. When the top-tier Explorer symbol is reached through repeated upgrades, the multiplier attached to it starts at a base value and increments with each subsequent retrigger. This escalating multiplier is the primary amplifier behind the 15,000x top win: a sequence of retriggers that upgrades to Explorer and then keeps adding multiplier increments creates exponentially larger expanding-symbol payouts across the 10 paylines.

Power Bet

Power Bet is an optional base-game modifier that costs 2x the regular stake per spin. Activating it increases the probability of triggering the bonus round by 170% compared to the standard bet. For players focused on maximizing bonus frequency rather than grinding the base game, it is a meaningful lever: the increased entry rate can offset the higher cost per spin depending on session length. Power Bet is available at Wild.io and is the equivalent of a light bonus buy option without the full buy-in cost, making it accessible across a wider range of bet sizes.
