Book of Kings Slot Review

Set among sand dunes and temples, the Book of Kings online slot is a five-reel, ten-payline game that follows a hugely popular theme. The Ancient Egyptian symbols include a fabled book that acts as others to help complete combinations.

It also launches a special free spins bonus round where expanding symbols enhance the odds of collecting a big prize. If a snake slithers over the triggering symbols, the rewards are even greater.

Play the Book of Kings slot online at Playtech casinos, and the maximum payouts can reach 15,000x your stake during the free games round.

Unearth a Legendary Book

Is there any subject more popular with casino game developers and players than Ancient Egypt? We doubt it, and as the Book of Kings slot machine from Playtech shows, there’s plenty of life left among the tombs and pyramids.

Like many online slot games based around Ancient Egypt, it stars an explorer, searching through dark corridors for untold riches. This beautiful woman is a high paying symbol, joining images of a pharaoh mask, winged god, Eye of Ra, and the colorful 10 to A on the reels. 

Palm trees and pyramids frame the main game and while it’s all very pretty, the standard of artwork is nothing exceptional. However, the draw of the topic is more than enough to make up for any lack of design flair. 

Although promoted as a Playtech slot, it’s actually the work of the Rarestone studio, which develops games on other developers' behalf.

Ten Lines of Egyptian Artefacts

You play the Book of King slot online with ten coins, setting the value of each from just 0.01 to a high limit of 50.00. That gives you overall staking options of between 0.10 and 500.00 for each spin. It’s fully optimized for iPhones, iPads, Windows, and mobiles that use the Android operating system.

Collect multiplies of the stake on a line with identical symbols, as shown in the paylines table below –

The Book of Kings online slot has an overall payback percentage of 96.5%. The high volatility tends to award relatively large prizes with less frequency than lower variance games. It’s an exciting format, but one that you should be aware of before you open up the game. Play Book of Kings for free right here, and you’ll soon see how any gaps between prizes can be well worth it.

Turn the Page for Bonus Features

The book is a valuable symbol in more ways than one. It’s a wild that can act as others if it's then possible to complete a winning line or extend a win across extra reels. 

It can’t substitute for the book and snake symbol, though. This is the scatter symbol of the Book of Kings slot machine, and if you see it in any three or more places, your reward is ten free spins. Before the game begins, three, four, or five scatters pay prizes of two, 20, and 200x your stake. 

An unusual mechanism means that the free games can trigger from both the wild book and the book and snake symbols, or both. If the book and snake contributes to the free games, all wins during the round get tripled in value. If it doesn’t, wins are paid at the standard rate.

Whatever way you trigger this feature of the Book of Kings slot machine, before each free spin the game software picks a random symbol to expand across any reel it lands on. This helps to create winning combinations, and if you are really lucky, the game picks the explorer, and she lands on all reels in the next spin. The free games retrigger if three or more books appear in a single spin. 

Hunt for More Treasures

One of the most famous explorers of all stars in an Egyptian adventure in the Lara Croft Temples and Tombs slot from Microgaming. Join Lara as she triggers cascading reels with rising multipliers and progressive jackpot payouts.

The Tootin’ Carman online slot from NextGen Gaming takes a humorous look at the subject, as a mummified pharaoh is on the loose in Las Vegas. He’s a wild symbol worth up to 500x your stake. The game comes with dice and Roulette-based mini-games that can unwrap big prizes.

Explore Book of Kings Online

The Book of Kings online slot is a perfectly decent Egyptian-themed game, with a potentially rewarding bonus round and high overall returns. It’s not the most visually impressive game we’ve ever seen, but if you like slots with this theme as much as we do, that shouldn’t matter too much.

Although there is just a single bonus feature, it’s a good one, with the chance to enjoy tripled payouts and massive wins from expanded symbols. 

The game is widely available across desktop and mobile platforms at sites featuring the Playtech range. Open the mysterious book at a recommended casino and discover the virtual treasures within.
