Overview

4 Of A King is a classic 5x3 slot from Endorphina with 10 paylines, aiming for that old-school land-casino vibe. The reels are filled with Croupier, Dealer, gamblers and coloured card icons, while a chip-shaped Wild spreads across adjacent positions. No free spins, no bonus buy, no scatters, just base game grinding with a gamble attached.

Game Details

RTP sits at 96.03%, volatility is flagged Medium-High, and the bet range runs from 0.10 to 200 EUR. That upper stake is generous for high rollers, but the math behind it is weak. Without a published max win multiplier and with the top-paying non-wild symbols only hitting 50x for a five-of-a-kind, the ceiling is too low for this variance.

For serious players, the numbers do not line up. Medium-High volatility usually implies a meaningful top prize to justify drought spins, and here that reward simply is not documented or promoted. With a proper bankroll you can stretch sessions at max bet, but the upside is not there.

Core Features

Two features, that is all. The chip Wild substitutes for every symbol and spreads over adjacent positions, which is the main source of meaningful wins in the base game. It is a decent mechanic, but it is doing all the heavy lifting alone.

The second feature is the Classic Risk Game, a standard gamble round where you can double your win. No Bonus Pop, no Free Spins, no multipliers, no scatter mechanic. For a bonus hunter, there is nothing to chase here, which kills the slot's appeal entirely from my angle.

Bonus Buy Options

Main Symbols

The chip acts as Wild and spreads to adjacent tiles, which is the only way to stitch together bigger combos. The Woman and Man share the second-highest tier, paying 50x the base bet for five of a kind. Below them sit the Croupier, Dealer, a Couple of gamblers, and four coloured playing card icons filling the lower end.

Paytable is thin compared to modern releases. With only 10 fixed lines and no ways mechanic, dead spin frequency feels high during longer sessions, and the low-pay card symbols contribute little to bankroll preservation at max bet.

Ryan Cole’s Verdict

Final Verdict

4 Of A King is a stripped-back classic that does its job for casual spinners, but from a high-roller perspective there is almost nothing to justify a serious deposit. 96.03% RTP is fine, the spreading Wild is fine, the gamble is fine. Fine is not enough when the variance is Medium-High and the visible top payout is 50x from non-wild symbols.

I would not commit bankroll to this one. No free spins, no bonus buy, no scatter, no multiplier stacking, nothing for a bonus hunter to target. If you want old-school casino atmosphere for low-stake fun, it delivers. For anyone chasing big-win potential, skip it and look elsewhere in the Endorphina catalogue.

4 Of A King FAQ
Does 4 Of A King have free spins or a bonus round?
No, the slot has no free spins feature and no scatter-triggered bonus. The only extra feature is the Classic Risk Game gamble and the spreading Wild in the base game.
Is there a bonus buy option in 4 Of A King?
No bonus buy is available. Endorphina confirms the game does not include a Bonus Pop feature, so you cannot purchase anything, the whole game runs on base spins plus the gamble.
How does the spreading Wild work?
The chip is the Wild symbol and substitutes for all symbols. When it lands, it spreads across adjacent positions on the reels, helping connect winning combinations on the 10 paylines.
What is the maximum bet I can place on 4 Of A King?
The bet range goes from 0.10 EUR up to 200 EUR per spin, which is suitable for high-stake play, though the overall win ceiling does not match the variance for that bankroll level.
What are the top-paying symbols and their value?
The Man and Woman are the equal second-highest paying symbols, each awarding 50x the base bet for a five-of-a-kind combination. The chip Wild sits above them as the substituting symbol.
