- An impressive sequel to Primate King from Red Tiger
- Plenty of welcome changes and a big win potential
- A bit of patience can really pay off
Following in the footsteps of Primate King and its Megaways cousin, Serpent King from Red Tiger sticks to the upgrade-the-wild formula, but throws in a few new mechanics to spice things up, including a multiplier bank and a sixth reel you have to unlock.
You start off on a 5-reel, 4-row grid with 30 paylines, but a sixth reel is lurking, locked away until you collect enough Gold Coins. Volatility is medium-high, RTP is a slightly improved 95.7%, and stakes range from 10p to £6 per spin. The premium symbols (necklace, potion, skull, treasure chest) can pay up to 30x your stake, and things get even more exciting once you start upgrading your Serpent Wild.

Serpent King Slot Bonuses and Features
Gold Coins & Progress Bar. Each time a Serpent Wild lands alongside Gold Coins, they’re collected and added to a progress bar. You’ll need:
- 30 coins for Upgrade 1
- 60 coins for Upgrade 2
- 90 coins for Upgrade 3
Once you’ve unlocked all three upgrades, the progress bar transforms into a fully active sixth reel. Better still, low-paying symbols can’t land on it.
Serpent Wild Upgrades. This is what sets the slot apart:
• Upgrade 1 – turns the Serpent Wild into a towering 1×4 stacked wild
• Upgrade 2 – adds a random multiplier of x2, x3, or x5
• Upgrade 3 – makes it sticky: it locks in place until it contributes to a win and then stays locked through any winning streak, increasing its multiplier by +1 with each hit
If no win occurs, the sticky wild may shift from the fifth reel to one of the first four to give you a better shot at landing something useful.
Multiplier Stone. Sometimes a wild will show up with a multiplier but not get used. When that happens, it stores its value in the Multiplier Stone, which sits next to the reels. The next time you land a Serpent Wild, the stored value is added to it.
Serpent Respins. Land a Serpent Wild without a win, and it might trigger this mini-feature. One symbol type is chosen and locked in place. A respin begins, and any matching symbols that land are also locked. Respins continue until no more of that symbol appears, and only that symbol type pays out at the end.
Conclusion
Serpent King slot from Red Tiger Gaming may follow a familiar trail as Primate King, but it’s not just a copy-and-paste job. It adds a few venomous twists to keep things fresh, such as the Multiplier Stone, Serpent Respins, and that nice 12,825x max win give it a bite that’s hard to ignore, especially when you consider it doesn’t even have a traditional bonus round. Yes, you’ll need some patience to upgrade your wild and unlock the sixth reel, but if you enjoy slots that reward time spent (and the occasional grind), Serpent King can definitely deliver.
