Slot Summary

King of Kings fills the gap between a compact Egyptian five-payline slot and a separate jackpot chase entered through an optional side bet. Relax Gaming released it in 2019, pairing high volatility and an x5000 ceiling with an extra-reel free spins mode. Ordinary spins remain restrained, while the Progressive Jackpot side game and changing reelset carry the larger shifts in pace.

How It Plays

Each paid spin uses five fixed paylines on a five-reel layout. A Wild can substitute for regular symbols, while the Scatter also functions as a Wild.

Two Scatter symbols start a Respin that locks both Scatters in place. Landing another Scatter during that attempt moves play toward the Free Spins trigger.

Theme & Atmosphere

Egypt supplies the royal setting, while Gems and Treasure keep the imagery tied to status and stored wealth rather than archaeological exploration alone.

The pharaoh, gods, and jewels frame the game as a contest for royal rank, giving its jackpot side game a clear connection to the theme.

Features & Win Potential

Reelset Changing separates the base game from Free Spins, where an additional reel allows combinations that cannot occur on the standard five-reel setup.

The Progressive Jackpot runs beside the main game through an optional side bet, adding a distinct prize route without changing the fixed-payline base format.

Bonus & Free Spins

Free Spins unlock the expanded reelset, shifting the round from the compact base layout toward longer symbol combinations and a different win pattern.

Respins provide a smaller bridge into that round by holding two Scatter symbols while another chance is played for the remaining trigger symbol.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (5,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
