Play Book of Kings Power Play Slot

If there’s one theme that never goes out of fashion in the slot world, it’s Ancient Egypt. Rarestone Gaming, in partnership with Playtech, taps into this ever-popular setting with Book of Kings Power Play, another addition to the long-running "Book of" genre. While the title doesn’t reinvent the wheel, it does introduce a Power Play Jackpot, giving players a potential shot at a progressive prize on top of the usual expanding symbol free spins.  

At first glance, the slot delivers everything you’d expect from an Egyptian-themed release. The 5x3 grid sits in front of the vast desert, with towering pyramids in the distance. With 10 fixed paylines, wins form from left to right across the reels, and bets start from a minimum of 0.10 per spin. The main attraction, as always, is the Free Spins round, where a randomly selected special expanding symbol takes over the reels. The game’s two wild/scatter symbols — the Book and the Book and Snake — also bring an interesting twist, as the latter comes with a 3x multiplier when triggering free spins. 

Rarestone Gaming, a studio under Playtech, has been responsible for several Power Play Jackpot slots, which link up to a progressive jackpot system. This means Book of Kings Power Play isn’t just another Egyptian slot — it has a jackpot element that can trigger at any time. It also follows a long line of similar releases from the developer, including Book of Kings, Book of Dwarves, and Egyptian Emeralds.

The reels are filled with classic Egyptian imagery, from Pharaohs to the Eye of Ra, alongside a mix of lower-value card symbols. A complete breakdown of all the symbols is given in the table below: 

The slot has two different wild symbols: the Book and the Book and Snake. Both can substitute for any regular symbol, but their role shifts depending on how they land. When three or more appear, they trigger Free Spins — and if the Book and Snake symbol is part of the trigger, the bonus round payout is tripled. 

Free Spins with Expanding Symbols 

Landing three or more Book or Book and Snake symbols activates the Free Spins feature, awarding 10 free spins. Before the round begins, a random symbol is chosen as the Special Expanding Symbol. If this symbol appears during the feature, it expands to cover the entire reel, paying out across all 10 paylines, regardless of position. 

Power Play Jackpot 

The Power Play Jackpot is a progressive prize pool, shared across multiple Playtech slots. It comes in three tiers: Mini, Peak, and Mega, and can trigger at any time during base gameplay. There’s no specific symbol required—once the jackpot meter reaches a certain level, the feature activates randomly, awarding one of the three jackpots. 

Book of Kings Power Play is another Egyptian-themed slot in a long list of "Book of" releases. Those who enjoy the expanding symbol mechanic may also like Legacy of Dead, Book of Ra Deluxe, and Enchanted Cleopatra, all of which offer similar free spin mechanics with special expanding symbols.
