Play Book of Power Online

Book of Power is a Relax Gaming video slot released on 8 March 2023 and developed with CasinoGrounds. The Ancient Egyptian game uses a five-reel, three-row layout with 10 fixed paylines, two Free Spins modes and expanding symbols. Regular Books open the standard round, while a red Power Book can lead to the enhanced feature with golden reels.

Book of Power Game Overview

Book of Power follows the familiar structure of a book-themed slot but adds separate progression systems to its two bonus modes. The base game evaluates matching symbols from left to right across 10 active lines, and the Book acts as both a wild and a scatter. Wins remain random on every paid game cycle, whether the Books appear or not.

Book of Power gives the feature design most of its detail through expanding symbols, retriggers and the Power Book. Standard Free Spins can collect several expanding symbols or add multipliers to symbols already selected. Power Free Spins instead upgrade one expanding symbol through the paytable and can make reels two, three and four count as golden reels.

Book of Power is listed by Wildz with an RTP of 96.11%, volatility of 8/10 and demo play enabled. Relax Gaming publishes a 15,000x stake maximum and a provider range of €0.10 to €60, although the controls and currency shown by an operator can differ. The information panel inside the opened game is the relevant place to confirm the active stake options and mathematical configuration.

How Does Book of Power Work?

Book of Power starts each paid round with all 10 paylines active. Matching ordinary symbols pay from the leftmost reel according to the paytable, while the Book can substitute for ordinary symbols and also serve as the scatter. The reels stop independently under the game’s random number generator before wins and feature triggers are evaluated.

Book of Power awards its main bonus when at least three Books appear. Three Books provide 10 Free Spins, four provide 15, and five provide 20; the presence of a Power Book can change the awarded mode to Power Free Spins. A higher stake changes the amount risked and the monetary value of a payout, but it cannot force Books or a bonus trigger to appear.

Book of Power Wild Book Symbols

Book of Power uses a blue Book as the standard wild and scatter symbol. The Book can replace ordinary paying symbols in line combinations, while three or more Books activate the regular Free Spins round. This dual function means the same symbol can contribute to a line result and to bonus qualification under the game rules.

Book of Power also carries a red Power Book when the relevant enhanced options are active. A triggering combination that includes the Power Book awards Power Free Spins rather than the regular mode. Neither Book can be summoned by a timing method or betting sequence, because its appearance remains part of the programmed random result.

Book of Power Expanding Symbols

Book of Power selects one of its nine ordinary pay symbols as an Expanding Symbol at the beginning of regular Free Spins. When enough copies land on separate reels, the symbol expands to cover those reels and then pays across all 10 lines after ordinary line wins have been counted. Premium symbols require two qualifying reels, while lower-paying symbols require three.

Book of Power can add another Expanding Symbol when at least two Books land during regular Free Spins, together with 5 additional spins. If the randomly selected symbol is already active, its multiplier rises by one instead, up to 9x. These upgrades affect later feature spins but do not guarantee that the required symbol will land in a paying arrangement.

Book of Power Power Free Spins

Book of Power awards Power Free Spins when the triggering set contains at least one Power Book. The initial award remains 10, 15 or 20 spins for three, four or five Books, but a retrigger upgrades the active Expanding Symbol to the next more valuable symbol and adds 5 spins. Once the top-paying symbol has been reached, later upgrades add one to its multiplier, up to 9x.

Book of Power can also turn reels two, three or four golden when a Power Book lands on the corresponding reel during this mode. A golden reel counts as though the active Expanding Symbol had landed there for the rest of that feature, even when the symbol is not visible on that reel. Golden reels improve the feature conditions but cannot ensure that enough other reels qualify for an expanding-symbol payout.

Book of Power Power Bet and Bonus Buy

Book of Power offers Power Bet outside Great Britain where operator and local rules permit it. Power Bet adds 100% to the regular stake, raises the stated chance of entering either Free Spins mode by 170%, enables Power Free Spins and can offer a gamble from regular Free Spins to the enhanced mode. The higher feature-entry chance is not a promise that a bonus will occur within any set number of rounds.

Book of Power also has provider-designed Bonus Buy prices of 100x the stake for regular Free Spins and 200x for Power Free Spins where permitted. Gambling Commission requirements mean feature-buy functionality is not offered by GB-licensed operators, so British play proceeds through the available reel triggers instead. Buying a feature in another permitted market changes the route and cost of entry, not the randomness of the resulting bonus round.

Book of Power Free Spins

Book of Power regular Free Spins combine the initial expanding symbol with the possibility of collecting further expanding symbols. Landing at least two Books during the feature adds five spins, and each new selection either activates another symbol or strengthens one already active. Expanded symbols are assessed after standard line wins and pay across all 10 lines when their reel requirement is met.

Book of Power Power Free Spins use a different progression path by upgrading one symbol rather than collecting a separate random set. Golden reels can then support that chosen symbol throughout the remaining round. Both modes can develop over time, but the number and position of Books and expanding symbols cannot be predicted from earlier spins.

Book of Power RTP

Book of Power has an RTP of 96.11% in the MGA configuration listed by Wildz. RTP is a long-run theoretical return calculated over a very large number of game rounds, rather than a forecast for one player or one session. Short results can finish above or below the published percentage.

Book of Power may exist in other mathematical versions for different jurisdictions, so figures from another market should not be substituted for the Wildz configuration. Players should open the information panel to verify the percentage attached to the version actually loaded. RTP does not remove the house edge or create a point at which a return becomes due.

Book of Power Volatility

Book of Power has a volatility rating of 8/10, which places it in the high-volatility range used by Wildz. High volatility generally means results can be uneven, with many low or non-winning rounds separated from less frequent larger outcomes. The two evolving bonus modes support that wider spread of possible results.

Book of Power volatility describes the distribution of results rather than the direction of the next spin. A losing sequence does not make a bonus or large win more likely to arrive, and an earlier payout does not reduce the programmed chance on the following round. Stake selection should therefore be based on an affordable limit rather than an attempt to recover previous losses.

Book of Power Maximum Win

Book of Power has a maximum win of 15,000x the stake. The cap can apply when a highly favourable combination of expanding symbols, golden reels and multipliers produces enough value during the game. It is a technical upper limit, not a typical result.

Book of Power stops further accumulation once the configured maximum has been reached under its rules. Most base-game rounds and bonus features finish far below that ceiling, including rounds that activate several enhancements. The maximum cannot be targeted by choosing a particular stake pattern or session length.

How to Play Book of Power in the United Kingdom

Book of Power play begins by opening the game, checking its paytable and selecting a stake made available by the operator. Pressing spin commits that amount to one game cycle, after which the reels determine line wins, Books and any bonus entry. GB-licensed versions do not provide the 100x or 200x Bonus Buy options.

Book of Power is also subject to Great Britain’s online slot stake limits when supplied by a Gambling Commission licensee. Customers aged 18–24 may stake no more than £2 per game cycle, while customers aged 25 and over have a £5 maximum. These limits control expenditure per cycle but do not alter the random probability of a winning result.

Can You Play Book of Power on Mobile?

Yes, Book of Power is listed in both the Wildz desktop and mobile catalogues. Book of Power presents the same five-reel layout, 10 fixed lines and bonus rules on compatible phone and tablet browsers. Screen size changes the presentation rather than the mathematical operation of the game.

Book of Power mobile performance can depend on the device, browser and connection used. Players should keep the information panel accessible and confirm the selected stake before starting a round on a smaller screen. Mobile access does not increase or decrease the chance of triggering either Free Spins mode.

Can You Play Book of Power for Free?

Yes, Book of Power has demo play enabled at Wildz. Book of Power demo mode uses virtual credits so the Wild Book, expanding symbols, Power Bet presentation and bonus rules can be inspected without staking deposited money. Demo winnings cannot be withdrawn because they have no cash value.

Book of Power free play remains random and does not train the game to produce a later real-money outcome. At Gambling Commission-licensed sites, age verification is required before access to free-to-play versions of gambling games. Demo mode should be used to learn controls and rules rather than to identify a supposedly profitable sequence.

Book of Power in the United Kingdom

Book of Power may be supplied in Great Britain by an online casino holding the appropriate Gambling Commission permission and carrying the Relax Gaming title. Book of Power players must be at least 18 years old, complete required verification and remain within the statutory stake limits. Availability at an individual licensed operator depends on its current catalogue.

Book of Power is listed internationally by Wildz, but Wildz states that visitors from the United Kingdom are redirected to partner casinos. Players should check the Gambling Commission public register for the business that ultimately supplies the game before depositing. The international catalogue alone should not be treated as proof that a business is licensed for Great Britain.

United Kingdom Rules for Book of Power

Book of Power real-money play in Great Britain is supervised by the Gambling Commission. Operators serving England, Scotland and Wales must hold the appropriate permission, and customers must have their name, address and date of birth verified before gambling. Free-play gambling games at licensed operators also require age verification.

Book of Power players should distinguish Great Britain from the entire United Kingdom when applying these rules. The Gambling Act 2005 system covers England, Scotland and Wales, while Northern Ireland has a separate legal framework for gambling. The Commission’s public register can be used to check the permission held by a British gambling business.
