Book of Power slot review

It sometimes seems that casinos are full of Book of… slots, but there is a reason for this: they are a great way to combine old, popular ideas with modern twists. The Book of Power slot looks simple with five reels and ten paylines.

Its Egyptian imagery, whilst incredibly well-designed, is nothing we haven’t seen before; however it really works. Our Book of Power slot review will explain this Relax Gaming slot in detail.

Everyone’s favourite civilisation

It is pretty clear that lots of people love the imagery and mythology of Ancient Egypt. Why else would it make so many appearances in slots? The unmistakable animal-headed gods, the magnificent pyramids still considered wondrous, the mysterious kings in golden masks and in the case of the Book of Power online slot, the tense and adventurous soundtrack.

Open the book

‘Book of Power’ is a pretty generic-sounding title that doesn’t tell you much except to expect Book of… mechanics. The scarabs on the front of the book symbols make things clear, as scarabs embody Ancient Egypt just as well as the shadowy temple setting and the winning symbols including the pyramid and pharaoh.

Book of Power RTP and variance

The Book of Power slot has an RTP of 96.11% The game is high volatility.

How to play Book of Power

It is time to explore:

  1. You can skip the opening sequences, but they are beautifully animated and we think they are worth watching.
  2. Once the game has loaded, you will want to know the payout potential of different symbols. You can find a link to the paytable in the menu; alternatively, click any symbol on the reels.
  3. The settings are also in the menu. If you want to separate the sound, sound effects and music, use the spacebar to spin or get rid of the splash screen and intro sequence, this is where to go.
  4. Adjust your bet levels with the plus and minus symbols. 
  5. Always play responsibly, using the timeout and self-exclusion features if necessary.

How to win at Book of Power

The Book of Power slot starts simply. There are ten paylines, which means ten ways you can line up matching symbols for a payout. There is no complicated Temple Tumble slot Megaways mechanics here.

  • With five reels, the best possible combinations have five symbols.
  • The lower-paying card symbols need at least three matches to pay.
  • For the four higher-paying themed symbols and the two book wild symbols, you can win with just two matches.
  • Each book wild also serves as a scatter symbol, triggering the Book of Power bonus features.

Top wins

The most valuable combination of winning symbols is five explorers, which earns you a 500x win multiplier. The same win multiplier applies to the book wilds. The max win is 15,000x. 

Bet range

You will find a bet range from £0.10 in the Book of Power slot.

Book of Power bonuses

Free spins

For most slots with a free spins bonus feature, the trigger mechanism is finding the scatter symbol during the base game. The Book of Power slot is no exception:

  • 3 books = 10 free spins.
  • 4 books = 15 free spins.
  • 5 books = 20 free spins.

During the free spins, one of the regular symbols becomes an expanding symbol. It will grow to fill an entire reel, potentially paying across all ten paylines. You can win five more spins in the round with an additional expanding symbol. If the already expanded symbol is chosen again, it gains a +1 multiplier.

Power bet makes it more likely you will trigger free spins. Power free spins work similarly to regular free spins but need a power book to trigger. They also have the potential to create golden reels on which symbols expand without the expanding symbol..
