Book of Power (Relax Gaming)

Book of Power Review

This release tackles the popular "Book slot" concept, blending tradition with innovation. It offers solid ancient Egypt visuals, animations, and a good spin pace. The regular bonus round can award additional special expanding symbols or upgrade their multiplier up to x9. The Power Spins round allows you to upgrade the top-tier symbol with a multiplier, provided you climb the paytable ladder via retriggers or get it from the start. The 15,000x potential is above average, making this a highly entertaining release.

Book of Power Slot Features

The Power Bet feature increases your bonus round chances. Activating this feature does not affect the RTP value. One additional benefit of the Power Bet feature is that you will be able to gamble for the top-tier Power Free Spins round when you trigger the regular bonus round.

The premium symbols, with the Explorer as the top-tier symbol, offer payouts for 5 of a kind wins. The low value symbols pay less in comparison, and this release comes with 2 Book symbols. Both book symbols act as wild symbols and also function as the game’s scatter symbols.

You win 10, 15, or 20 free spins when you land 3, 4, or 5 Book scatters anywhere in view, and this also awards an upfront payout. The book opens to select the special expanding symbol before the feature starts, and this symbol expands to create full line wins if you land enough instances anywhere in view.

The special symbol does not need to land on adjacent reels to expand and pay. You get an additional expanding symbol if you land 2 Book scatters on the same free spin, and this also gives you +5 extra spins. If the new special symbol is already active, it gets +1 added to its multiplier instead. You can get up to an x9 multiplier.

You trigger the Power Bonus Round if one of the triggering Book symbols is the Power Book, and this also gives you 10, 15, or 20 Power Free Spins with an upfront scatter win. A random pay symbol is once again selected to become the special expanding symbol, and it works as described above.

The big difference is that the current expanding symbol gets upgraded when you land 2 Book scatters on the same free spin, and this also awards +5 extra spins. If you manage to upgrade the special expanding symbol to the top-tier Explorer symbol, additional retriggers will add +1 to the multiplier for the expanding version of the symbol up to x9. Landing the Power Book on reels 2, 3, and/or 4 upgrades the reel to become golden. Golden reels count as the expanding symbol even if the special symbol does not appear on it.

The Hot Mode feature can trigger in both tiers of the bonus round, and it will trigger at the start of random free spins. This increases your likelihood of landing a larger payout on the spin that follows. Non-UK players can purchase the bonus round. The Power Spins feature will cost more, and the bonus buy RTP increases.

The 200 Spins Book of Power Slot Experience

You get a decent taste of the base game. We purchase the Power Free Spins round right after the 1-minute mark, and we got the royal symbol ‘K’ as our special expanding symbol. We managed to upgrade the symbol a few times, which also prolonged our session, and you can check it all out in the video.

Review Summary

Book of Power comes with an excellent spin pace with the turbo switched on. The changes they have made can have a powerful impact when things go your way.

You get the traditional ancient Egypt theme, with well-crafted visuals and animations. The regular bonus round is unique thanks to the possibility of multiplier upgrades or extra special symbols. The Power FS round stands out even more, as you’ll upgrade the special symbol until you reach the top of the paytable, and after that its expanding multiplier gets upgraded up to x9. It all adds up to a solid installment, and the 15,000x potential is higher than what you get in most other ‘book slots’.
