Primate King: Climb the Wild Upgrade Ladder
Primate King is a jungle-themed slot from Red Tiger Gaming built around a clever progression system rather than a traditional free spins round. Instead of waiting for a bonus to trigger, you steadily upgrade the King himself across a single session, turning a modest Wild into a screen-shaking force. It is a colorful, fast game with a clear hook: collect coins, climb the ladder, and watch the gorilla grow more powerful with every step.
Reels, Paylines and Layout
The game runs on a 6x4 grid with 30 fixed paylines, paying left to right from the leftmost reel. The sixth reel is special: it stays inactive at first and only switches on once you have completed every Wild upgrade. When it does, it lands high-value symbols exclusively, which is exactly when the biggest combinations start to appear. Until then you play across an effective five-reel field while building toward that final unlock.
The Primate Wild Progress Bar
The heart of Primate King is the Primate Wild Progress Bar. Gold Coins that land on the reels fill the bar, and each completed stage permanently enhances the Primate Wild for the rest of your play. There are three upgrades, applied in order:
- Stacked Wild: the Primate Wild becomes a tall 1x4 stacked symbol, covering a full reel and creating far more chances to complete lines.
- Multiplier Wild: a random multiplier attaches to the Wild, boosting any win it helps form.
- Sticky Wild: the Wild locks in place, staying on the reels until it takes part in at least one win and is then followed by a non-winning spin.
Because the upgrades stack, a fully levelled Primate King can drop a sticky, multiplied, full-reel Wild onto the grid, which is where the game's real potential lives.
Primate Smash Feature
Primate Smash is a smaller in-play extra that keeps the base game lively. If a Primate Wild lands without forming a win, the King can smash the reels, clearing away the low-paying symbols so a fresh set drops in. The result is a guaranteed second chance at a winning combination from a spin that would otherwise have come up empty.
Symbols and Top Prizes
The paytable splits into the usual two tiers. Royal card values fill the low end, while the themed jungle symbols pay the premiums, topped by a treasure chest. The Primate King gorilla is the Wild, substituting for all paying symbols. The largest single combination on the paytable returns 900x your stake, and across a full run the game can pay up to a maximum of 3,800x your bet.
RTP, Volatility and Hit Rate
Primate King carries a return-to-player of 95.66%, which sits below the 96% mark many players treat as average, so it is worth knowing going in. Volatility is medium to high, and the published hit frequency is around 28.76%. In practice that means a reasonable flow of small and mid-sized wins while you build the progress bar, with the heavier payouts concentrated once the Wild is fully upgraded and the sixth reel comes into play.
Betting Range and Mobile Play
Stakes run from 0.10 up to 50 per spin, giving the game plenty of headroom for both cautious and high-rolling sessions. You can try the Primate King demo to learn the upgrade rhythm.

Take a look at Great Gold for another upgrade-driven jackpot chase, Roman Emperors for a history-themed spin on the studio's sharp design, or Lucky Valentine for a brighter, more playful set of reels.
