Tombs and temples await slots fans in Book of Kings by Playtech. In this high variance game you’ll learn the story of a young explorer searching far and wide for boundless riches among the sarcophagi of Giza. On the reels you’ll find symbols such as the explorer herself, an ancient Tutankhamun pharaoh lookalike, the heraldic eagle symbol of Egypt and of course, the Book of Kings itself!
There is a visual theme here that, if you’re a regular slots player, you’ll be extremely familiar with. Ancient Egypt is without a doubt the most popular setting for slot games both online and offline. That should not take anything away from Playtech’s effort with Book of Kings though; the game looks and sounds fantastic and the gameplay is top notch.
There are 10 paylines to be struck in Book of Kings. Couple that with the higher-than-average return to player percentage of 96.63% and the high variance and you can expect a great gameplay experience. The wins in Book of Kings should, in theory, come at you slower than in other slots - but expect each win amount to be on the higher side.
If you’ve played a Playtech slot game before then the Book of Kings controls should be fairly intuitive. On desktop the controls are positioned along the bottom third of the screen. When the game loads you’ll see a small ‘i’ symbol on the bottom left which will show you what each symbol means and the payouts.
One of the disappointing aspects of the Book of Kings controls is the autoplay function. On most modern online slot titles you can set stop conditions when autoplaying - meaning that if you win or lose a certain amount the reels will immediately stop spinning. In Book of Kings there are only two types of stop conditions available.
One is the ‘until feature’ which means the game will only stop when you hit a free spins round. Another is setting the amount of spins you want to play. The problem with both of these stop conditions is that they don’t take into account potential wins or losses - so if you aren’t monitoring the game screen closely you might not notice any dramatic changes in your balance. For this reason we would advise foregoing the autoplay function in Book of Kings.
That gripe aside, the Book of Kings slot controls work well. It is available to play on both Android and iOS and there are no noticeable differences in how the game runs or its visual quality between devices.
Book of Kings isn’t packed to the rafter with free spins and bonus features. However the two main features that exist in the slot can pack a punch when landed:
The book and snake symbol is the scatter of the Book of Kings. If you spot it in three more more spots on the reels you will receive a ten free spins bonus. The more scatters the more the paid prize will be. For example three scatters will pay 2x your stake and five scatters will pay 200x your stake. As a nice extra every win during a ‘book and snake’ round will be subject to a 3x multiplier!
The book symbol (without the snake!) is the most useful wild in Book of Kings. It is a wild that will substitute for other symbols making a win possible or extending a win that’s already landed. Get three of these symbols and you will also activate the free spins feature - albeit minus the 3x win multiplier.
The maximum win you can achieve in Book of Kings is 15,000x your original stake. This is done by landing an expanding female explorer symbol across every reel during the advanced free spins round. This is normally 5000x but with the 3x multiplier attached the win becomes colossal!
Book of Kings has an RTP of 96.63%. This means that 96.63% of the total amount put into the machine is paid back to players, with the remaining 3.37% going to the casino as house edge. Compared to other slot games this is an above-standard RTP amount. The game is high volatility which means that wins will come less frequently but generally at higher amounts.
Book of Kings is a fun game to play. The Ancient Egypt theme has been done to death by slot developers and is definitely an oversaturated space. That being said, Playtech have done a great job with this game, providing a balanced and exciting experience for all levels of player. While the theme is so-so the gameplay is great and at the end of the day that’s what matters.
