Book of Power Slot

Another title in its “Book of…” series, Book of Power is Relax Gaming slot, featuring the standard ancient Egypt theme, and quite the usual features and layout.

The slot is based on a 5x3 grid and offers 10 fixed paylines. It is highly volatile and offers an average RTP, on top of several features revolving around Expanding Symbols. For a deeper understanding of how video slots like this one work, check out our complete guide to video slot machines.

There are two types of Free Spins and Book symbols that play important roles, in addition to a Hot Mode and two Feature Buy options. If you’re ready, let’s go straight to reviewing.

In the background of the Book of Power real money slot, you’ll see a realistically-depicted ancient Egypt temple, with two statues on the sides of the reels. You also see the developer has marked the paylines, in old-school style, so you have better insight into how you’re forming wins. In the left bottom corner, you see the Power Bet button, to be discussed below.

The setting buttons are in the footer. You first see the three-bar button, which leads you to the paytable. Once inside, you’ll see the low-paying playing card Royals with golden details, giving you 10x to 15x the stake, followed by the four high-paying symbols, the ancient Egypt-inspired symbols like pyramids, sphinx, and scarabs, and the Explorer, giving you up 75x to 500x the stake for a 5-of-a-kind combo. The Buy button is next, where you can use one of the two Bonus Buy options, to be discussed later.

The Bet Configuration field is next, where you could place a regular bet from $0.10 to $30. This is where the Power Bet could be activated, doubling the stake and increasing the chance of triggering any of the two Free Spins by 170%. The Autoplay and Play buttons are next, followed by the Win and Balance Displays.

We mentioned that the slot offers two Book symbols, one regular and one Power Book. Both, however, are used as Wilds, to substitute for any symbol which is in its regular size, not expanded.

And they both play the Scatter role to trigger the Bonus Rounds. Therefore, these two Book Symbols will be crucial in the slot.

As said, there are two different Book of Power bonus rounds. You trigger the regular Free Spins with 3 to 5 Books, for which you get 10, 15, or 20 Free Spins, respectively, plus a 10x, 100x, or 500x the stake payout. Here, one symbol is taken at random to be the special Expanding Symbol. If these symbols form a win, they Expand to cover all positions on the respective reels, paying from any position. Land 2 more Books and you get 5+ Free Spins plus an additional random Expanding Symbol. If the chosen symbol is already an Expanding Symbol, you get a 1+ Multiplier, up to 9.

You get the same number of Free Spins and the same payout for triggering the Power Free Spins, but with 3, 4, or 5 Power Books. Again, a symbol is chosen to be an Expanding one, which gets upgraded by one step when 2 Books hit, plus you get 5+ Free Spins. If it upgrades to the highest-paying symbol, for each Expanding Symbol you land, you get 1+ Multiplier, up to 9. Plus, if you land a Power Book on any of the middle reels, the reel becomes Golden, and even if there’s no Expanding Symbol on it, the chosen Expanding Symbol will appear and expand.

The Hot Mode can be triggered at random at the start of any of the two Free Spins Bonuses, increasing your chances to trigger a massive payout. You can purchase the regular Free Spins for 100x the stake, while the Power Free Spins for 200x the stake, thanks to the two Bonus Buy options.

While the Book of Power slot offers these exciting special features that boost your gameplay, it's also important to consider maximizing your bankroll outside the game.

Should you play the slot without the Power Bet active, the RTP will be 96.11%, but with it active 96.50%. The slot is highly volatile, 5 out of 5 on Relax Gaming's volatility scale, and the maximum payout it can offer is 15,000x the stake.

So, if you play it for the max bet level of $30, the slot can deliver a max payout of $450,000. This is a really exciting payout to grab, especially since the max bet is only $30.

We have to admit that Relax Gaming did not only create another “Book of…” slot, but it actually created it to be really modern and with pretty realistic visuals. The gameplay is fairly exciting, too, especially with the addition of the Hot Mode, which significantly improves your chances of winning big. The max payout potential is excellent, considering the max bet is only $30, so no matter what you do, do not miss it out in our highlighted online casinos.
