Slot Basics At A Glance

I spun King of Kings for the first time on a lazy evening and right away noticed how lean it feels: just 5 reels, 3 rows, and a mere 5 paylines. You stake anywhere between 0.10 € and 50 €, so even cautious testers can give it a shot before bumping bets. The release date is 21 March 2019 and, in my experience, Relax Gaming rarely messes up core math, so I trusted the figures. The setting leans heavily on the unmistakable vibe of Ancient Egypt; two falcon‑headed statues guard the border‑free grid while dunes shimmer far behind.

Sound design is mellow—mostly wind whooshes and a spaced‑out drum beat. I like subtle loops, yet players who crave throbbing audio may feel it’s a bit too tame. Paylines count left‑to‑right only. Among the eye‑catchers, Tutankhamun’s portrait is the standout premium, and Bastet comes next with her golden grin; a full line of the boy‑king can land 200× your bet. On mobile the game squeezes into portrait mode neatly, so commuting spins are no hassle.

Look And Feel Of The Pharaoh's Court

The art direction mixes cartoon edges with light 3‑D shading, which in my view keeps things readable when the reels start rolling fast. A neat touch is how symbols seem to float without borders; the screen doesn’t look cluttered. Betting mechanics are super straightforward: hit “–” or “+” until the stake meets your mood, press Spin, done. Because the grid is compact, you always see the entire paytable at a glance—handy for newcomers.

Maximum win peaks at 12 500× stake, pushing the slot into tier A on my personal scale. That ceiling is high enough to matter yet not so wild that odds look fake. Payouts trigger strictly from the first reel, so you never chase both‑ways fantasies here. I would have welcomed a tiny line or two telling the back‑story, but the visuals alone still make the plot clear: seek royal riches and ignore the desert heat.

Returns, Risk, And Bankroll Advice

King of Kings posts an official RTP of 96.25 %, which sits in the healthy tier B range. Relax Gaming does not operate an adjustable RTP scheme, so what you see in the paytable should match the server config whichever casino you pick—good news for value hunters. Having said that, you should still double‑check the help screen every new venue just to be safe.

The slot is tagged high volatility; during my sessions I hit plenty of barren stretches before a chunky screen of expanding symbols paid for the silence. If you like adrenaline swings, you’ll enjoy it, but I’d suggest at least 500 bets in the wallet to ride out the sandstorms. Players who prefer smoother balance curves might call the math brutal, yet that brutality is exactly what enables the 12 500× ceiling.

Bonus Symbol Re‑Spin Feature

Miss two scatters and, occasionally, the game throws you a life‑line: reels hold the triggering Ankh icons, a random symbol is picked to behave like an expanding bonus, and you receive a single respin. If fresh Ankhs pop in, another respin follows—simple loop, yet it builds suspense rapidly. I’ve seen it fill the grid with Tutankhamun once, awarding 1 000× and wiping out an earlier losing streak. The frequency feels modest, maybe one in fifty spins, but when it hits you sense real momentum.

Free Spins With The Sixth Reel

Three or more golden Ankh Scatter symbols unlock 10 free rounds and, crucially, bolt an extra reel onto the right, turning the layout into six‑by‑three. Payout lines remain at five, yet with a bigger canvas full‑screens show up easier. Immediately before the bonus starts, one regular icon (excluding wild) is chosen to expand whenever enough copies land—two premiums or three low symbols will do. I think the mechanic resembles Book‑style slots, but the extra reel spices it up; 5000× per spin becomes possible without multiplier gimmicks.

Triggering again retriggers another 10 spins, though in my tests that happened rarely. Still, the base hit chance improves because wilds remain dual‑nature—standing in for everything while also being the scatter trigger. I appreciate how straightforward the rules stay; nothing distracts you from spotting expanding panes sliding into place.

Extra Bits I Noticed

Wild symbol: The golden Ankh substitutes for all icons and carries its own paytable—land five for 1 000×. Because it also acts as scatter, two Ankhs can already hand back 2× bet, softening dry patches.
Multiplier touch: Expanded screens of premium symbols inherently multiply line prizes across five (or six) reels; there’s no separate modifier, yet the math still stacks sizeable totals.
Jackpot Stars Side Bet: For 0.10 €–2 € optional wager you enter a mini draw where colored balls spin; fill all columns with reds and you snatch the fixed 12 500× jackpot. I only flirt with it when bankroll feels healthy—odds are long.
Free Spins retrigger chance: Extra Ankhs during bonus add ten spins and upgrade the expanding symbol, which can escalate payouts fast, but don’t count on it each session.
Scatter pay flexibility: Because Ankhs reward from any position, two on reels 1 and 5 may still buy the respin feature even when paylines look empty.

Benefits And Drawbacks

Pros:

• Extra sixth reel in free spins boosts screen‑full potential

• Dual wild/scatter keeps odds of feature entries reasonable

• 12 500× top prize is juicy without being outlandish

• No adjustable RTP trickery to worry about

Cons:

• Five paylines feel stingy; many spins show nothing at all

• Audio loop is calm to the point of sleepy if you like loud slots

• Side‑bet jackpot can drain balance quicker than it pays
