Book of Power Slot Review

Teaming up with Casinogrounds, Relax Gaming bring another ‘book of’ title to our reels. Book of Power follows the general ancient Egyptian theme, with the slot set in a dusty old tomb. The presentation here is spot on, with great art direction and sound that immerses you in the mystery of it all.

But looks aren’t all this slot has going for it. Two Book symbols trigger their distinct free spin bonuses, complete with expanding symbols and win multipliers. You can opt-int in through the buy feature to jump straight into the action.
But, does Book of Power manage to reinvigorate the ‘book of’ genre, or is it just another run-of-the-mill release? Check out our full review below to find out.

Book of Power Bonus Features

Relax Gaming brings the big guns to Book of Power, throwing in all manner of video slot features to make every spin an exciting event. The Book symbols themselves are responsible for the action, triggering two distinct free spins bonuses. Gameplay is upgraded during the bonus rounds, with expanding symbols, win multipliers and the randomly triggered Hot Mode coming into play.
It’s a great combination, although unfortunately, the base game does suffer from a complete lack of special features.


The book symbols serve as Book of Power’s wild symbols. They come in regular book and power book formats, substituting themselves for any pay symbols that could form part of a winning combination.

Scatter Symbol

The book symbols also serve as the slot’s scatter symbols. Regular book symbols trigger normal free spins, while power book symbols trigger the upgraded power free spins. 3, 4 or 5 symbols trigger 10, 15 or 20 free spins on their respective bonus and a payout of 10x, 100x or 500x your selected bet respectively.

Free Spins

In regular free spins, a pay symbol is selected at the start of the bonus to be the special expanding symbol. Whenever they form a win, these special symbols expand to cover their respective reels. Any additional wins that the expanded symbols trigger are added to the original win. If you land two book symbols during bonus play, a new special symbol is selected and added to the existing one/s. Should the newly selected special symbol be the same as an existing special symbol, then it gets an added multiplier of +1, which can be maxed out at 9x. You also get an additional 5 free spins.

If you trigger the upgraded power free spins, gameplay follows a similar structure to the regular bonus, with a few noteworthy additions. Landing 2 book symbols will automatically upgrade your special symbol’s multiplier. Additionally, getting a power book symbol on reels 2, 3 or 4 makes that respective reel golden, with expanding symbols activating even if they didn’t form part of a winning combination.

Hot Mode

Available in both free spin bonuses, hot mode can randomly trigger at the start of any free spin, increasing the odds of landing a huge win that can bring you closer to the 1,500x maximum prize.

Buy Feature

If you don’t have the patience to wait for the book symbols to trigger free spins, you can hop straight into the bonus fun with the buy feature.
Regular free spins cost 100x your selected bet, while the supercharged power free spins will set you back 200x your selected bet.

Book of Power Jackpot

You’ll find no dedicated jackpot prizes lurking around Book of Power’s tombs. But you can still land some impressive wins with a maximum win cap of 1,500x your selected bet.

RTP & Volatility

Book of Power clocks it’s volatility at a high setting. This gives you infrequent but big rewards that are well worth the wait. Elsewhere, return to player rate is set to 96.11%, which is pretty standard for this type of game. However, there are some more slots that you can explore on our list of highest RTP slots and try your luck for even bigger winnings.

Where to Play Book of Power

Book of Power can be found at a vast range of online casinos that support Relax Gaming. Personally, we’d recommend you play it over at Playluck. You can even take advantage of the 100% up to £50 welcome bonus, which also throws in an additional 30 free spins.
