Book of Power Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 10 paylines

Stakes Range: 10p to £30 per spin

RTP: 96.11%

Max Win: 15,000 x bet per spin

The Book of Power slot is a typical ‘Book of’ game with 5 reels, 3 rows and 10 fixed paylines. Winning combinations are created when 3 or more matching symbols appear from left to right, on adjacent reels, and across any of the 10 paylines. For the 4 highest value symbols, 2 or more are needed for a win.

Bets in Book of Power range from 10p to £30 a spin. Under or to the side of the reels, there is a ‘Bet’ box. Click/press the plus and minus icons to change your bet accordingly. If you like click/press the actual bet amount, a scrolling menu appears with all options. This is the same in all Relax Gaming slots.

Non UK players can use Autoplay for unlimited autospins with single win, loss and win limits. For quicker spins, there is a Turbo Mode. As with Autoplay, this feature isn’t available at slot websites in the UK.

The Book of Power RTP is 96.11%. Higher than the 96% slots average, it’s about the norm for a ‘Book of’ slot game. As expected, the volatility/variance is very high (5/5). With a winning combination landing every 3.25 spins on average, the hit frequency rate is 30.7%.

When it comes to payouts, the Book of Power slot comes with 15,000 x bet max wins. A screen full of the top value symbol will result in a 5,000 x bet payout but there are increasing multipliers in the free spins.

Theme – head to ancient Egypt and find the illusive book

Theme: Ancient Egyptian

High Value Symbol: Adventurer

Compatibility: Mobile, Tablet, Desktop

book-of-power-slot-base-game

With an ancient Egyptian theme, the Book of Power slot takes you another adventure to the pyramids. Produced in co-operation with CasinoGrounds, the setting is the entrance to an ancient tomb. Graphically, it’s bold and colourful with animated high value symbols.

The soundtrack is brilliant and immersive. Adding to the intensity, visually it looks like Push Gaming’s Mystery Museum slot in that the symbols are horizontally quite big. Whilst it may be another ‘Book of’ slot, Relax Gaming have worked hard on giving it a unique feel. It has a Tomb Raider/video game quality to it visually though.

On the reels, you will see A, K, Q, J and 10 royals. Higher value symbols include pyramids, scarab beetles, pharaohs and the adventurer. The adventurer is the best paying symbol with 1, 10, 100 or 500 x bet awarded for 2, 3, 4 or 5 in combination across any payline.

Importantly, there are 2 Book symbols which are wild and substitute for all paying symbols outlined above. 2, 3, 4 or 5 Book symbols will pay 1, 10, 100 or 500 x bet too. They also trigger their own bonus feature (more details below). Here’s a table showcasing payouts/functions for all Book of Power symbols:

Book of Power Mobile

book-of-power-mobile-slot

Despite being set in ancient Egypt, the Book of Power slot was released on the 8th of March 2023. This means it was produced using HTML5 technology. This allows for play on mobile, laptop, PC and/or tablet devices. The 5×3 layout works well on mobile devices which includes iOS, Android and Windows operating systems.

Book of Power Bonus Features

The Book of Power slot comes with 5 bonus features. With 2 free spins features, retriggers give you more free spins and an extra expanding symbol. If your chosen expanding symbol is active, the multiplier increases up to 9. In the Power Free Spins, the expanding symbol upgrades with the multiplier increasing up to 9x once you have the adventurer expanding symbol. Power Book symbols make reels golden which expand symbols automatically.

Free Spins feature

book-of-power-slot-free-spins-feature

The Free Spins feature is played when 3 or more Book symbols land anywhere on the reels. 3, 4 or 5 Book symbols will award 10, 15 or 20 free spins respectively as well as 10, 100 or 500 x bet.

Like in countless other ‘Book of’ games, a special expanding symbol is randomly selected in the Book of Power slot. During the feature, this chosen symbol will expand to take over the whole reel if it can form a winning combination.

For example: if you were to have 3 chosen symbols on the reels at once, 3 reels will be occupied by the chosen symbol. The more lucrative the special expanding symbol, the bigger your potential wins. Here’s a table highlighting payouts for 5 full reels of the same symbol:

Symbol(s) Max Win (5 full reels)
10, J, Q 100 x bet
K, A 150 x bet
Pyramid, Scarab Beetle 750 x bet
Pharaoh 2,000 x bet
Adventurer 5,000 x bet

More importantly, if 2 Book symbols landing during a free spin, an extra special expanding symbol is awarded as well as 5 extra free spins. If the special expanding symbol is already active, the multiplier will increase by 1.

The multiplier can rise up to 9x. With up to 8 retriggers possible for all 9 symbols to be expanding, you can benefit from 40 additional free spins in total (so max 60 free spins). If various expanding symbols land, they will all award payouts. This means you can get wins from various symbols on each free spin.

Power Free Spins feature

book-of-power-slot-power-free-spins-feature

The Power Free Spins feature is triggered by landing 3+ Book symbols with 1 Power Book symbol. 3, 4 or 5 Book/Power Book symbols will give you 10, 15 or 20 free spins with 10, 100 or 500 x bet respectively.

Like in the Free Spins feature, a special expanding symbol is randomly chosen. Look out for Book symbols as 2 will give you 5 additional free spins. However, the special expanding symbol is upgraded to the next more valuable symbol. If you already have the adventurer as the expanding symbol (the highest paying), the multiplier increases by 1 up to 9x.

There’s more though. Keep an eye out for the Power Book symbol landing on the 3 middle reels. When it appears, the Power Book turns the corresponding reel golden for the remainder of the feature. This means the expanding symbol will expand on golden reels even if no expanding symbol lands on that reel.

Hot Mode feature

The Hot Mode feature can be randomly triggered at the start of the Free Spins or Power Free Spins features. Basically, it increases your chances of winning big during the features.

Power Bet feature

To increase your chances of triggering the Power Free Spins feature, there is a Power Bet feature. If enabled, it increases the chance to trigger any free spins game by 170% for an increased cost of 100%.

Buy feature

Finally, the Book of Power slot comes with a Buy feature element for players outside the UK. You can buy your way into the Free Spins feature for 100 x bet whilst it costs 200 x bet for the Power Free Spins feature.

Originality








Visually, the Book of Power slot is brilliantly produced. Whilst it ventures into old ancient Egyptian ground, the graphics and animated high value symbols really add to the experience to make it look more like a video game. It’s clear that Relax Gaming have spent a lot of time on the artwork and look/feel.

Produced in co-operation with CasinoGrounds, Book of Power is the 4th slot in the series. It follows Iron Bank, Net Gains and Beast Mode. Truth be told, the 3 previous releases are better graphically as their themes are not as restrictive as ancient Egypt.

In terms of the gameplay, it comes with free spins with special expanding symbols. Yes, pretty ordinary. However, retriggers will give an additional expanding symbol and 5 more free spins. This however has been seen in Play ‘n GO’s Legacy of Egypt slot. The difference is that the multiplier can increase by 1, up to 9x, if the special expanding symbol awarded is already active.

In the Power Free Spins feature, retriggers see the special expanding symbol upgraded. Once you have the adventurer as the expanding symbol, retriggers see the multiplier increase by 1, up to 9x. The key is the Power Book wild/scatter which turns reels gold. In turn, expanding symbols expanding on golden reels no matter if they appear on them or not. It could lead to 3 gold reels which expanding symbols expand on.

That said, the max win per spin or free spin is 5,000 x your total bet. This can be won by filling all positions with the high value adventurer symbol. The Book of Power slot offers 15,000 x bet max wins. It’s clear this can only be won in both the free spins features as a whole.

In summary, Book of Power is a well-produced slot game which looks great and offers a couple of twists on the ‘Book of’ concept. If you’re a fan of this kind of slot, it’s well worth playing.

My pick would be the Book of Shadows slot by Nolimit City. You have the option of playing with 10, 15 or 20 paylines as well as 30,338 x bet max wins.

Pros
  • 15,000 x bet max wins
  • Innovative 'Book of' game with a few twists
  • Brilliant graphics/imagery
Cons
  • Very high volatility (5/5)
