You can check the RTP rating of a Relax Gaming online slot in the game info upon loading.

Whisps float around the sandy Egyptian statues and stone columns that blur in the background on Book of Power, providing a focus highlight on the reel set. The highly-detailed symbols wave and bulge and the explorer reacts to game events, giving the occasional wink. Book of Power is beautifully presented and one of the most polished versions of a book game you will find in 2023. Classical Egyptian music adds to the mood with dramatic intent.

The pay symbols start at the low end with 10, J, Q, K and A, which pay 10x or 15x your stake for matching five on a pay line. A pyramid, sarcophagus, Pharoah’s death mask, and explorer symbols follow, awarding from 75x to 500x your bet for five-of-a-kind.

A book acts as the wild scatter symbols, substituting for all others in win combos and triggering free spins for landing three or more. Regular Blue Books trigger Free Spins, and landing a Red Power Book in a scatter combination upgrades the bonus to Power Free Spins.

Book of Power Slot Features

Book slots can lay claim to fame as one of the most played genres in online gaming. Many classics emerged since Edict introduced the design on Magic Mirror before Play’n GO mimicked the mechanic and Book of Dead took casino lobbies by storm in 2016. With Relax Gaming being known for its innovation, an inspired remake of a classic game design commands attention.

Before taking your first spin on Book of Power, you can choose to enable the Power Bet feature for each spin. For double your regular bet, Power Bet enables Red Book scatters for a chance to trigger Power Spins and increases the chance of activating Free Spins by 170%. Using Power Bet does not affect the RTP.

When ready, a basic spin will see you matching symbols from left to right along pay lines for a win. Assisting with wins is the Book scatter symbol, which substitutes all others and serves to trigger Free Spins for landing three or more. With Power Bet enabled, there is a chance of landing a Red Power Book scatter. Any combination of three Blue Book or Red Power Book scatters will activate Power Spins.

Landing three or more Blue Book scatters triggers the Free Spins bonus. Three, four or five scatters award 10, 15 and 20 free spins, respectively. At the start, one symbol from the paytable is randomly chosen as a special expanding symbol for the round. Upon landing, standard pays are calculated before examples of the chosen symbol expand to fill their reels, awarding wins based on scatter pays across all pay lines. For example, expanding symbols covering four reels will pay four of a kind on all pay lines.

The pay symbols are displayed beside the reels in a meter, highlighting the currently chosen special expanding symbol. Landing a further two or more scatters on a free spin awards +5 free spins and +5 for each additional scatter, plus an additional special expanding symbol for the remainder of the round. Should the newly awarded special expanding symbol match the currently active one, an x2 multiplier is applied to the chosen symbol. It is possible to fill the meter with all eight paytable symbols active as special expanding symbols.

Land a Red Book scatter in a combination of three or more to trigger Power Free Spins. Three, four or five scatters award 10, 15 and 20 free spins, respectively. The Power Bonus works in the same way as the regular Free Spins bonus by selecting a special expanding symbol for the round and awarding extra spins for landing two or more scatters. However, instead of granting an additional expanding symbol selection, landing a further two or more scatters upgrades the currently chosen symbol to the next most valuable one.

Furthermore, land a Red Book scatter on reels 2, 3 or 4 to turn the reel golden, activating a Gold Reel. Gold Reels guarantee a special expanding symbol on that reel for each remaining spin of the bonus. Reach the top of the symbol meter to activate the explorer symbol with an x2 multiplier. Further upgrades will increase the multiplier in x1 increments to a maximum value of x9.

Where available, you can skip the main game and dive straight into a free spins bonus using the Bonus Buy feature. There are two Bonus Buy options for a fixed amount that both come with a 96.50% RTP rating:

  • Free Spins | 100x Bet: A Free Spins bonus trigger with a guaranteed minimum of three scatter symbols.
  • Power Free Spins | 200x Bet: A bonus triggering spin of Power Free Spins with a guaranteed minimum of three scatter symbols.

Final Verdict

Book of Power looks and feels fantastic and stays close to the style that makes Book of Dead by Play’n GO so alluring. The game is undoubtedly set up to rival the classic, and brings improved production and design, plus a few attractive twists in gameplay.

For starters, more than one symbol can be chosen as the special expanding symbol for the bonus, a popular feature from other hits like Edict’s Magic Mirror Deluxe II and Thunderkick’s Sword of Khans. Furthermore, there are multipliers for repeatedly chosen special expanding symbols and Power Spins, where reels of gold guarantee they hit on every spin. Throw in a 15,000x max win, and you have a modern classic in the making with bags of appeal.

Book of Power is suitably titled, providing a powerhouse of classical book game action in a glorious skin. A ‘must-spin-slot’ for book fans, which represents the cream of the popular genre in 2023.
