With its Egyptian theme and potential for wins up to 10,000×, it offers a mix of classic gameplay and slightly expanded features, though it still leans heavily on the traditional format.
How to Play King of Kings
The slot uses a 5‑reel, 3‑row layout with just 5 paylines. Wins are formed by lining up symbols across these fixed lines. Scatter symbols act as wilds and trigger features. A unique Bonus Symbol Re‑Spin occurs when you miss the third scatter—granting 1 free spin with a randomly chosen expanding symbol, which can deliver strong payouts if premium icons land.
