King of Kings

• They’ve become a staple in the world of online gaming, and King of Kings is no exception. But if you’re not already a fan of this genre, this one probably won’t change your mind. The developers certainly love this formula, but for those who aren’t into it, you might want to look elsewhere. At first glance, King of Kings doesn’t offer much that stands out, except maybe the borderless reels. You’re looking at the standard 5 reels and 3 rows, but here’s the kicker: the paylines are cut down to just 5, unlike the 10 or more we’re used to seeing from big names like Novomatic or Play’n GO. It’s an odd decision that might leave some players scratching their heads.

Slot Features

• King of Kings adds a bit of a twist to the traditional “book” slot formula, though it doesn’t stray too far from the basic concept. One notable addition is the Bonus Symbol Re-Spin, a feature that kicks in when you miss the third scatter. Essentially, it functions like a mini-bonus round. You’re granted 1 free spin with a randomly selected expanding symbol, giving you the potential for a solid payout — up to 1,000x your stake if you fill the screen with Tutankhamun symbols.

• The real twist comes with the Free Spins feature. This is triggered by landing 3 or more wild scatter symbols on the reels. Once activated, you’ll receive 10 spins, and here’s where things start to change: the reel area expands to 6 reels, which increases your chances of hitting big wins. Like the Re-Spin feature, one symbol is chosen as the special expanding symbol, and it will cover the entire reel when 3 low-value symbols or 2 premium symbols land. With 6 reels in play, your max win potential jumps to 5,000x your stake. However, the game’s fact sheet claims wins of over 10,000x have been recorded, so there’s definitely room for some massive payouts.

King of Kings (Relax Gaming): Verdict

• At its core, King of Kings is a classic “book” slot that doesn’t necessarily bring anything revolutionary to the table. The inclusion of a 6th reel and some extra features does add a slight twist, but it doesn’t fully transform the gameplay. It’s still the same one-dimensional format, and honestly, the extra reel feels somewhat unnecessary, especially since it doesn’t dramatically alter the odds. In essence, it’s more about creating the illusion of added value — much like when a slot adds a fourth row but sticks with a fixed number of paylines, making the change feel more cosmetic than functional.
