Book of Kings Main Features
- With a potential win of more than 5,000x your bet, this 10-payline slot game is one that is done stunningly well. Be it the way the game is designed or the way the artifacts in Ancient Egypt are given attention to detail, this game has some serious win potential.
- We don’t want to spoil the surprise too much, but there is the possibility of landing a 3x multiplier in the free spins bonus round boosted by expanding symbols.
- The Book of Kings slot game is slightly different from the several slot games that target the Ancient Egypt theme. The game is not set within the pyramids but rather outside in the heat of the desert.
- The game is played out on 5 reels, 3 rows and 10 fixed paylines. Similar to the Book of Dead slot game by Play’n GO, this game sticks to a simple format that makes it popular. You will also benefit from a free spins bonus round with a randomly chosen expanding wild as well as 3x multipliers.
Book of Kings on Mobile
Like all modern online slot games, Playtech has updated its old portfolio of games and made its new games mobile-friendly. As a result, all the games work like a charm regardless of the operating device or system. Whether you want to play on your commute to work or straight from your couch, you can do so. The game adapts to the contours of the various screen sizes without losing any quality or features.
Book of Kings RTP and Variance
The Book of Kings slot RTP hovers at a slightly higher than average 96.63%. This payout percentage is considered a quite high RTP value for a slot game in this day and age. This game also enjoys high variance, which means wins will come by on a semi-infrequent basis. The maximum win you can achieve in the Book of Kings slot game is 5,000x your bet.
Book of Kings Special Symbols
As always, you can find a mix of game-related symbols which are usually the higher paying symbols as well as a mix of card suit numbers, which act as the lower paying symbols.
- The lowest paying symbols pay out between 50x and 75x your stake for five of a kind on a payline. This is then followed by the Eye of Ra and Horus which pay out 375x your bet.
- The highest paying symbols include Tutankhamun and the female adventure which pay out 1,000x your stake and 2,500x your stake for five of a kind respectively.
- The Book and Snake symbol acts as the game’s wild symbol. This too pays out 1,000x your stake for five of a kind.

Book of Kings Slot Bonuses
To hit any winning combinations you would need to land a number of identical symbols on a payline. The Book of Kings slot game comes with fixed paylines, so no adjustments need to be made to activate all paylines. Below, you will find all the available features in this game.
Free Spins Bonus Feature
The free spins bonus round is where all the action takes place in this online slot game. You would need to land three or more Book and Snake or Book symbols on a single spin. When this happens, you will immediately receive 10 free spins. There is also a difference in the multiplier depending on the symbols that triggered the free spins bonus round:
- 3 or more Book scatter symbols award you 10 free spins with a 1x multiplier
- 3 or more Book and/or Book and Snake Symbols grant you 10 free spins with a 3x multiplier
Before you kickstart your free spins bonus round, a symbol will be randomly chosen as the game’s expanding symbol for the duration of the round. If you successfully land an expanding symbol on all 5 reels, then you will get a spectacular win. You can only hope that you will get the female adventurer as she is the most valuable.
Book of Kings Free Spins Paytable
Here’s a table of the payouts expected in the free spins round:
| Symbol | Win (1x Multiplier) | Win (3x Multiplier) |
| 10 | 100x | 300x |
| J | 100x | 300x |
| Q | 100x | 300x |
| K | 150x | 450x |
| A | 150x | 450x |
| Eye of Ra | 750x | 2,250x |
| Horus | 750x | 2,250x |
| Tutankhamen | 2,000x | 6,000x |
| Female adventurer | 5,000x | 15,000x |
It is also possible to retrigger the free spins bonus round by landing more scatters. In total, you can receive 20 free spins.
Expanding Symbols
As mentioned, before the free spins bonus round commences, a random symbol will be randomly picked out to act as the game’s Expanding symbol. Whenever it lands, it will expand to fill out entire reels leading to huge payouts.
Conclusions
Players who are fans of the ‘Book Of’ series or are familiar with the popular Book of Dead slot game by Play’n GO, will definitely appreciate this one. This is simply because it does have an advantage over other similar games. It has the potential to pay out with a 3x multiplier boost in the free spins bonus round.
That said, it is a highly volatile game, so you do have to wait for the free spins bonus round for big wins to be generated in this game. You may want to watch out for your bankroll until the big wins start to roll in.
