Relax Gaming has a new slot release, one that will leave you speechless with the gameplay it has to offer. You will be playing 2 games in 1, simultaneously, as both the base and the Jackpot game have a different RTP, different set of reels, different bets and different symbols present on the reels. Intrigued yet?

Betting and Prizes

There are 5 paylines in King of Kings, where the betting starts at $0.10 but can go up to $25.00. Now, you can place an additional bet of up to $2.00, to activate the possibility to play the Jackpot Stars game where you could win one of 6 jackpot prizes. Therefore, the maximum bet you can place in total is $27.00. The RTP varies. In the base game, the slot offers 96.25%, but in the Jackpot Stars game, it offers a RTP of 96.00%.

The Jackpot Stars can give you a 12,500x the stake payout. This translates to $25,000.00 for the highest $2.00 bet for the Jackpot Stars game. The highest winning combo with Wilds gives you $50,000.00, while with Tutankhamen, you get $25,000.00. These are all amazing payouts, but not as amazing as the maximum payout potential of 10,000x the stake, as told by the developer. $250,000.00 from the main game and $25,000.00 from the Jackpot Stars game equals $275,000.00 which is an incredible sum.

King of Kings Slot Features

The Wild is also the Scatter in the slot, so it substitutes for all symbols on the reels. Three of more Wild symbols trigger 10 Free Spins on an additional reel. This is when the game chooses one symbol, other than the Wild, to be a special Bonus symbol for the duration of the Free Spins, thanks to the Bonus Symbol Upgrade feature. When these Bonus symbols create a winning combo, the Bonus symbol expands and covers the entire reel, moves to the left and gives payouts on all lines.

When only 2 Wilds appear, the game might randomly surprise you with the Bonus Symbol Re-Spin feature. Again, any symbol except for the Wild can be a Bonus Symbol for a single Re-Spin. But, when 2 Wilds appear during the Free Spins, you get 1 additional Free Spin, and when 3 or more of them appear, you retrigger the 10 Free Spins and you get the Bonus Symbols to appear again.

At any point of the base game, the Jackpot Stars symbol may appear. To trigger the Jackpot Stars game, all 3 Stars of the Jackpot Stars symbol must be lit. This is when you get a different set of symbols, essentially Red Balls, and you get 6 reels instead of 5. All reels, then, which are not filled with a Sticky Symbol, start spinning. When they stop, the Red Balls cascade on any reel position and stay Sticky until the game ends. As long as a reel has been completely filled with a Sticky Symbol, the spins continue. You can also be given a Re-Spin at random, once for every spin. When no more spins or Re-Spins are possible, the feature ends. If you get to fill all reels with Red Balls, you win one of the 6 jackpots.

Theme & Design

Two Horus statues will welcome you in this beautifully designed slot, but soon you will notice the borderless reels, the pyramid and the dunes in the background.

The reels present some sort of a temple, we guess, and on them, you will find 9 symbols as the standard, base game symbol set. Red, blue, yellow, green and orange scarab gemstones will be the lowest-paying ones, while the Egyptian deities Anubis, Bastet and Horus will be the higher-paying ones. You get a cartoonish picture of Tutankhamen as the highest-paying symbol and the golden Ankh symbol that assumes both the role of a Wild and Scatter on all reels and delivers the max payout from the base game to you. For the special Jackpot Stars game, you get a different set of reels filled with Red Balls.


King of Kings is an impressive new slot. It is packed with features that actually award incredible bonus rounds and boost your payouts. You get to play through so many spins for free and collect some superb rewards out of those free spins. The max payout potential is massive, and the gameplay highly engaging and interesting. You probably understood by now that this game is the king of slots, even though titled King of Kings, right? Try it the minute you can, you will be fascinated by it.
