King of Kings slot game review

King of Kings is a “Book of Ra-style” slot from Relax Gaming, and it was released 3 April 2019. It comes with a Re-spins feature when you land only 2 scatters, but per usual in the book-type slots it’s the Free Spins feature with the expanding symbols that will land you the big wins. The potential is the usual 250,000 coins, and as most Book-slots this is a highly volatile game and not for the faint of heart.

King of Kings RTP, variance & technical data

Before we take a closer look at all the fun features you’ll find on King of Kings slot, we shall reveal the game’s most relevant technical data for you:

  • RTP: 96.25%
  • Volatility/Variance: High
  • Layout: 5x3
  • Paylines: 5
  • Bonus features: 6-Reel Free Spins, Re-Spin and Bonus Symbol Upgrade
  • Bets: 0.1 to 50
  • Max wins (coins): 250 000

King of Kings comes with a rather average RTP, and this is also a highly volatile game. It’s wise to adjust your bet level according to your bankroll. This way you can handle the dry spells that are bound to come between the bigger wins on this game.

King of Kings Review

King of Kings is yet another Book of Ra style slot, but this time from Relax Gaming. Players just don’t seem to get enough of these kinds of games, Simplicity combined with high potential and a theme from ancient Egypt seem to have some kind of magical appeal. That being said, if you don’t like the “Book” type slots you’ll probably be better off playing something else, as this game will probably not win you over.

The number of ways to win has been cut from 10 to 5 on King of Kings, but you can also benefit from an extra reel in the all-important free spins feature. This is where you can win the big money, and you’ll get 10 free spins with expanding symbols to help you. The max win is 250,000 coins or 5000 times your stake, and there is also a similar re-spin feature that might give a win up to 1000 times your stake in the base game. A decent game from Relax, but we don’t think it will dethrone Play’n Go’s legendary Book of Dead.

King of Kings bonus features

In the base game you’ll find a bonus feature called the Bonus Symbol Re-spin feature. Whenever you land only 2 scatters this bonus re-spins might be triggered. This will give you 1 free spin with an expanding symbol chosen at random. You can win up to 1000 times your stake in the base game if you full the screen with the Tutankhamun symbols.

King of Kings free spins

The free spins feature is the main attraction on King of Kings slot, and you’ll trigger this feature when you land at least 3 wild scatter symbols on the same spin. This will reward you with 10 free spins, and the reel area is also expanded with a sixth reel.

The free spins feature plays out just like the re-spin feature. One symbol will be chosen at random as your “special” expanding symbol, and it will cover the reels completely whenever you land 3 low value symbols or 2 high value symbols, respectively. You can really win big in the free spins feature, as we shall see below.

King of Kings jackpot (max win)

Since you’re playing with 6 reels in the free spins mode, the max win is now a whopping 5,000 times your stake per spin. While there is no progressive jackpot to be won on King of Kings, you can still win up to £250,000 if you play with the highest stakes. The max win in the base game is “only” 1000 times your stake, so the free spins feature is really all-important on this game.

King of Kings mobile & tablet

You can certainly play King of Kings slot on both mobile and tablet, and this game works fine on any handheld device or platform. You can play anywhere you go as long as you have an internet connection, and you can play on your Android devices or your iPhone and iPad.

SlotCatalog verdict

King of Kings is a slightly original twist on the Book-type slot that we’ve seen many of since Play’n Go’s massive success with Book of Dead. Why they’ve decided to cut the number of paylines in half we do not know, but the potential is still 5000x your stake in the free spins feature (even though you have a 6th reel here). The Re-spins feature beefs up the base game somewhat, and if you enjoy the “Book slots” you just might wanna give this game a try.


  • Free spins with expanding symbols
  • Re-spin with expanding symbols
  • Book-type slot with high potential and volatility


  • Yet another Book-type game
