How to play King of Kings mobile slot

This King of Kings mobile slot has a whole load of treasure hiding in these beautiful reels, but is the price you need to pay too high?

We have to admit that we’ve come to enjoy playing on Relax Gaming slots. They look beautiful and sometimes even surprise us; just look at the brilliant The Great Pigsby slot or even the way they made the Temple Tumble Megaways slot feel different.

And this King of Kings online slot certainly seems to follow the trend of beautiful machines with wonderful themes. It may not be particularly unique, but with Ancient Egyptian gods on the reels, and beautiful gems, it certainly stands out.

King of Kings is a 5 reel 3-row slot machine with 5 fixed paylines, wild symbols that also act like scatters and free spins played on 6 reels. You also can place an extra bet to win a 25,000 cash jackpot.

We particularly love that on mobile phones and tablet, the reels move closer, so all the focus is on the symbols over the 5 reels.

How much are you willing to pay to win big?

That’s the question you have to ask yourself when you play this real money slot, as the biggest win is through the jackpot star button.

That’s the question you have to ask yourself as you have to buy an instant cash bonus: for an extra 0.10 a spin could win you 1,000 in cash, or 2 a spin, could win you 25,000 in cash.

These amounts don’t change regardless of how much you bet and bear in mind the wins have nothing to do with this extra bet. All it does is that randomly you trigger an instant cash game where you can win as little as 10x up to 12,500 x your bet.

So don’t be tempted to bet too high just for one feature.

Can you catch the King of Kings slot free spins?

If you do, you’ll get a 6 reel slot machine which is where all the really good slot wins are hiding in this five payline game. Namely, because you can randomly turn one of the paytable symbols into a wild and scatter.

It makes re-triggering the free spins that little bit easier, and catching six of a kind wins all the more possible.

The problem is that if you’ve been paying for the highest jackpot, the free spin winnings don’t always cover the cost of that bet. Really, we wouldn’t recommend this to anyone who isn’t willing to gamble at least 10 a spin.

And that’s a little too elitist for us. We like online casino slots where anyone, of any betting range, can get involved, and that’s why we’d say that the Machina by Relax Gaming is probably a better choice, with wins to rival this King of Kings video slot.

Bonus Features

Wild Scatter: The wild symbol substitutes for all other symbols on the reels for payline wins. Wild also acts like a scatter, so it triggers the bonus games.

Bonus Symbol Re-spin: When two wild show you, the game may surprise you and give you a respin of the reels where one of the paytable symbols will become the bonus symbols. Creating a better chance of triggering the free spins.

Scatters and Free Spins: 3 or more wild symbols start 10 free spins and unlocks an additional reel giving you 6 of a kind wins. One symbol can also randomly be picked to also act like a wild. When a number of bonus symbols that constitute a win appear, that symbol is stamped to cover complete reel, moves to the left and pays on all lines.

Jackpot Star: You can place an additional bet that will randomly let you play for a jackpot. The higher you bet, the bigger the jackpot you can win.

  • 0.10 bet: 1,000 jackpot
  • 0.20 bet: 2,000 jackpot
  • 0.50 bet: 5,000 jackpot
  • 1 bet: 10,000 jackpot
  • 2 bet: 25,000 jackpot

This feature triggers randomly. You will then get to re-spins lottery balls onto reels - the more red balls you land on the reels, the higher the prizes you win.

King of Kings Review Conclusion

This King of Kings slot on mobile looks great. As far as Egyptian casino games go, we can't fault it.

However, a few obvious flaws make it hard for us to recommend it. It's frustrating that you need a six of a kind win to get anything decent, and even more frustrating that those are only in the free spin bonus games.

It's just as frustrating that you have to pay a fairly high fee just to occasionally buy yourself an instant cash bonus. Mobile slot games like the Triple Cash Wheel slot may not have as big a payout, but at least you are not betting twice on the same machine for two different prizes.
