CasinoGrounds and Relax Gaming Make Book Slot on Steroids – Book of Power!

Relax Gaming and CasinoGrounds have created a new slot based on the old classic. It’s called Book of Power, and it’s scheduled for release on March 8. What could be so revolutionary about another rendition of a tried and tested slot theme? The hint is in the name because this familiar-looking slot brings, like Jeremy Clarkson would say, more power! It even has a Hot Mode in the bonus, during which there’s an increased chance of winning big, up to 15,000x bet, that is.

CasinoGrounds is an affiliate site that’s known for its streamers. This is not the first time that the developer and players’ community have come together to create a game. They’ve also made slots like Iron Bank, Beast Mode, and Net Gains, which came out in December. In part to good marketing, all their games have proven quite popular also because they aim to tweak the game from the player’s perspective.

Aside from great graphics, Book of Power doesn’t appear to be any different from its 10-line analogues. The crux is in the details.

What’s a “book” game without a free spins bonus with a special expanding symbol? Book of Power has one too, which can award up to 20 Free Spins, but the best part is that landing just 2 extra Book symbols during the bonus will activate a different expanding symbol, plus 5 free spins. If it happens to be the same symbol already selected, it’ll be played with a +1 multiplier! Re-triggers can happen multiple times; the point is to get the same symbol as many times as possible for bigger multipliers.

If the Power Bet is enabled, which doubles the total bet, players are in for the chance to win the enhanced free spins bonus called the Power Free Spins and otherwise increase the feature entry chance by 170%! The biggest difference is that landing a Power Book symbol on a reel 2, 3 or 4 will turn that reel golden, and the expanding symbol will expand even without landing one! Additionally, there’s also a Hot Mode mentioned above, which can trigger during this or the regular bonus to boost the chance of winning even further. The stats show that the average win in the Power Free Spins is 117.59x bet vs 101.65x bet in the regular.

A sneaky alternative to winning the bonus is to buy your way through by paying a 100x bet for the regular bonus and a 200x bet for the Power one, using the Bonus Buy. Unlike Power Bet, it may not be available in certain jurisdictions. The good news is that, as a result, the RTP will also increase from 96.11% to 96.50%.

Having played the game, we can attest that there’s something to the added features that fans may enjoy, even for the sake of variety, but all that makes this slot very volatile, so it’s not for everyone’s taste! Try it for yourself at Relax Gaming casinos when it comes out in less than two weeks, in addition to Relax's own hot new games announced for this year.
