Playtech have launched the latest addition to the Book Of series, with this new version - Book of Kings. It has all the familiar features that players know and love, pa...cked into a high-volatility game played out across five reels and ten paylines, with an RTP of 96.63%. The Book is both Wild and Scatter, with special Expanding Symbols during the Free Spins bonus round. But if a snake helps to trigger the bonus, you’ll benefit from a 3x Win Multiplier, boosting the potential top prize to 15,000x your stake.

Introduction
Slots game developers are always returning to the subject of Ancient Egypt for their games. But thanks to female equality, exploration and archaeology are no longer considered exclusively male pastimes. We’ve seen it before with Lara Croft Temples and Tombs, and now there’s a new heroine in town. And she’s ready to explore some of the reputedly cursed burial chambers of the Pharaohs. It’s time to light our torches and follow her down into the depths of the pyramids.
Graphics and Sounds
As you’d expect from Playtech, the graphics are of excellent quality, and the game perfectly captures the mood of an Egyptian adventure. When it comes to the music, it all sounds suitably authentic, until the wins start stacking up. For some reason, the developers felt that it would be perfectly acceptable to add in a few fairground-style jingles, which killed the mood somewhat.

RTP & Volatility
Book of Kings has a very reasonable RTP of 96.63%. But this is a highly volatile game, so we advise plenty of demo play before risking any cash on its reels.
How to Play Book of Kings
1 Set the amount of your bet using the buttons at the bottom right-hand corner of your screen.
2 Activate Spin to start your game.
3. Autoplay is situated just to the left of Spin, giving you the option of using automatic spins at your current bet level.
4 Use the bottom left menu button to access the game’s paytable and rules.
Min & Max Bets + Top Wins
Every player will be able to find their perfect wagering option, thanks to the comprehensive range on offer. Play from as little as 0.10 per spin up to a maximum of 500.00 per spin.
Maximum payouts are to be found during the Free Spins bonus rounds. If your Expanding Symbol manages to cover all five reels, the prizes can be off the scale, particularly where the bonus multiplier has been triggered.
Here are the top prizes that can be won for achieving Expanding Symbols across every reel. The first figure shows the prize sum during the standard Free Spins round, while the second figure shows the prize with the 3x Multiplier applied.
Q, J, 10 = 100x, 300x
A, K = 150x, 450x
Ra, Eye of Horus = 750x, 2,250x
Pharaoh = 2,000x, 6,000x
Female explorer = 5,000x, 15,000x
Bonus Features & Free Spins
The Book serves a dual function in Book of Kings, acting as both the Wild and the Scatter. It substitutes for other symbols, helping to form winning combinations. It comes with its own paytable too, so you win a cash prize for spinning up three or more, in any position on the reels. As Scatters, they don’t have to conform to the usual payline rules.
Free Spins
Three Scatters in view will trigger the Free Spins bonus round, awarding you 10 Free Spins. But if one or more of the triggering Book Scatters happens to have a snake on it, every win throughout the bonus round will be subject to a 3x Multiplier.
Expanding Symbols
In a feature that will be instantly familiar to every Book Of fan, just before the Free Spins begin, the Book flips open and scrolls through all available symbols on the reels. It picks one at random to act as the Expanding Symbol throughout the feature. It will expand to fill entire reels, potentially creating some huge payouts.
Overall Review
Fans of the popular Book Of series of games will find a great deal to like on the reels of Book of Kings. The look and feel of the game is instantly familiar, if you’ve played any of the other games. This one plays out particularly similarly to Book of Dead. But it’s that potential 3x Win Multiplier that can appear during the Free Spin Bonus that really lifts the game above the rest.
If you love Book Of slots, you’re definitely going to love this latest addition. And if you’re not familiar with the other titles in the series, give this one a go anyway. Just be careful if you decide to play with real money - the high volatility makes it all too easy to rip through your bankroll before the big wins have a chance to start rolling in.
