Overview

The King from Endorphina is a medieval 5x3 video slot with 10 fixed paylines, high volatility and a 96.07% RTP. I see it as a compact old-school model, built around a simple payline setup, a strong free spins feature, and two classic add-ons, Risk Game and Bonus Pop. The numbers tell you the profile straight away, hit frequency is 22%, so the base game is not dense.

From a math perspective, the slot is fairly direct. The ceiling is 9000x, the free spins round gives 15 spins with a 3x multiplier, and Wild-assisted line wins are doubled. That creates a top-heavy return curve without using modern reel modifiers or cascades. I like the clarity, but the base game can drag a bit.

Paytable & Symbols

Paytable structure is narrow, because the game runs on just 10 paylines and a small symbol set. The Crown is the Wild, it substitutes for all regular symbols except Scatter, and five Wilds pay 900x the base bet. More importantly for expected value on individual hits, any winning combination that includes a Wild is doubled.

Lion is the Scatter, and five of them pay 500x the base bet. Looking at the paytable structure, the top standard symbols are the man and woman symbols, each worth 75x for five of a kind. The theme also uses a King, Archer, Treasure Chest and Coat of Arms, but the review material does not list full prize steps for every symbol.

Game Features

Bonus value sits in the Free Games round. Three or more Lion Scatters trigger 15 free spins, and every win in the feature is multiplied by 3. Extra scatters can re-trigger the round. In practical terms, this is where most of the slot's meaningful upside sits, because the multiplier is fixed and active across the full bonus.

Base-game enhancement comes from the Wild multiplier rather than reel expansion or symbol collection. Every line win that contains a Wild is doubled, which gives the regular game some punch despite the low line count. After any win, the Risk Game lets you try to double the payout by beating a dealer card. Bonus Pop is also available, giving direct access to the bonus in supported markets.

RTP, Volatility and Win Potential

96.07% RTP puts The King slightly above the long-run market average, but the variance profile is still high. With a reported 22% hit frequency, around one spin in five returns any win at all. From a math perspective, that means stretches of low feedback are normal, and the slot relies on bonus access and occasional doubled Wild hits to compensate.

Maximum win is 9000x, which is decent for a 2015 fixed-line slot, though not exceptional by current standards. Bet range runs from 0.10 to 90. The model is easy to read, fewer mechanics, fewer moving parts, and most of the EV is concentrated in the 15-spin feature rather than spread across layered side systems.

💬 What Players Say
Coverage points to a straightforward high-volatility slot with a solid free spins round and old-school gamble feature. Feedback is mixed on presentation and depth, with some seeing the base game as a little plain. Based on 3 reviews.
Ryan Cole’s Verdict

Final Verdict

Verdict is quite clear. The King is a straightforward high-volatility slot for players who still like fixed paylines, visible symbol values and a bonus round that does one thing well. I think the strongest part is the free spins package, 15 spins, 3x on every win, and re-trigger potential. That is clean and mathematically coherent.

Weaknesses are also obvious. The theme is serviceable rather than distinctive, and the base game can feel sparse because 10 lines and a 22% hit rate do not create much constant action. Not everyone will enjoy this volatility. Still, if the target is a classic slot with a bonus-led payout profile, the game does its job well.

Every win during the free spins round is multiplied by 3. Extra scatters can re-trigger the feature and extend the bonus.
What does the Crown Wild do apart from substituting?
The Crown substitutes for all regular symbols except Scatter, and any winning combination that includes a Wild is doubled. Five Wilds pay 900x the base bet.
Does The King have a bonus buy option?
Yes, the game includes Bonus Pop, which gives direct access to the free spins round. Availability can depend on jurisdiction.
