Relax Gaming King of Kings Slot Review

Form a winning combination with 3+ matching symbols placed on adjacent reels from the leftmost. Like in all similar titles, the paytable combines themed icons representing various Egyptian deities with lower-paying jewels of different colors, shapes, and values. The coin value ranges from €0.01 to €5 allowing players to wager between €0.10 and €50 per round, as per their betting strategy.

We know that players are used to seeing Wilds as icons with dual nature, but this game additionally extends their usability. First of all, you can use Wilds to improve the payline, as well as to replace all paying symbols. Moreover, Wilds are also Scatters and a predefined number of them will trigger the King of Kings Free Spins.

Initially, 3 Wilds/Scatters activate 10 rounds at the casino’s expense with the layout extended to 6 reels. A randomly-chosen symbol is designated as a Special Symbol that may cover the full screen should be accumulated in a sufficient number.

With 3+ Wilds/Scatters, you will get 10 extra spins and upgrade Special Symbol to the one with a higher payout rating. As all this isn’t enough, 2 Wilds/Scatters grant an additional King of Kings Free Play round.

You will also benefit from this very symbol in the base game where 2 Wilds may reward a Surprise Bonus Re-Spin and turn another icon into Special Symbol under the same conditions as described above. This feature works no matter if you play for fun or for real money.
