When you spin the reels of 4 of a King by Endorphina you step into a card game meets video slot world where classic symbols combine with straightforward mechanics. The green and brown palette feels like a nod to old-school casino tables, yet the medium volatility and 96% RTP promise a balanced ride for casual players and modest risk-takers alike. I gave the feature-packed free spins round a whirl and appreciated how a simple wild can spark bigger wins without overwhelming the base game.
4 of a King unfolds on a standard 5-reel, 3-row grid with 10 fixed paylines running left to right. You set your credit stake, hit spin, and watch as card suits and royalty icons line up in familiar patterns. The pace is unhurried, letting you savor each win or near-miss, and the controls are intuitive enough that even newcomers can jump in without consulting a guide.
• A classic card suit theme brought to life with crisp brown and green visuals
• Ten steady paylines that keep things simple and accessible
• Wild symbols that step in for missing cards, boosting your chance at combos
• A free spins feature that often delivers extra rounds and occasional retriggers
• 96% RTP paired with medium volatility for balanced playtime and wins
With 10 betways on a 5×3 layout, 4 of a King keeps the experience uncluttered but still satisfying. The mobile-friendly FLASH technology renders smoothly across devices, so you can spin on desktop or tablet without lag. A 96% return-to-player suggests that for every 100 credits wagered, about 96 come back over a large sample of plays. While that does not guarantee tidy returns in a single session, it offers a fair shot over time.
Medium variance means wins arrive steadily rather than in a drought or a deluge. Smaller payouts happen often enough to maintain momentum, while the wild icon can step in to complete paying lines when you least expect it. I noticed that triggering the free spins round feels like cruising into a bonus table: three scatter cards unlock an initial batch of spins, and once inside you might retrigger more. The top prize remains modest compared to high-roller slots, but those looking for simple win potential can appreciate the clarity of these limits.
Understanding RTP and variance helps you pick a game that matches your appetite for risk. At 96% RTP, 4 of a King offers an industry-standard long-term return which might appeal to players who dislike extreme swings. Meanwhile medium volatility usually reserves larger payouts for the bonus round rather than the base game. Combined with wild substitutions and free spins, this setup can keep sessions lively without demanding a deep bankroll.
The slot’s brown felt background and green accents create a faux-casino atmosphere reminiscent of tabletop card battles. Suit symbols and picture cards have a subtle shine that nudges you toward classic poker tables. Sound effects tap into that museum-quiet casino hum, so wins pop without feeling overstated. Compared with Endorphina’s glitzier titles, 4 of a King feels more refined, trading animation fireworks for a timeless card-deck vibe.
Landing three or more scatters kicks off the free spins feature, typically rewarding eight spins to start. During free spins wilds can expand to cover an entire reel, upping the thrill when a full column turns high-value. Though the bonus round is straightforward, I found the retrigger chance satisfying and not overly rare. One catch: wins in the free spins are paid at the same rate as in the main game, so if you crave huge multipliers, you might find this round a bit conservative.

• Use demo mode to test the pace before risking real credits
• Adjust your wager in response to session results—consider lowering bets after a big bonus
