Primate King: Slot Overview

Developer Red Tiger gets its rage on in jungle-themed slot Primate King, bursting at the seams with angry apes. When you think of 'rage' in connection with slots, rampaging gorillas are one of the first images to emerge. These distant relatives of ours regularly appear on the reels in various forms, though interestingly, this appears to be the first time they have done so for Red Tiger. Mathematically speaking, Primate King mirrors the brutal nature gorillas have a reputation for in a game which uses an upgrade/reel unlocking mechanism borrowed from a previous release.

Never one (okay rarely one) to turn out an ugly-looking game, Red Tiger nevertheless outdid themselves when designing the lush environs that make up Primate King's setting. It's not so obvious in a still shot, but when you see the animated jungle shifting and swaying, it's easy to pretend you’re in a steaming hot location, heaving with life. Several skulls placed about the screen add a touch of danger while bringing to mind the King Kong/Skull Island imagery. Primate King certainly wouldn't be as enjoyable if the graphic quality weren't so high, making the location so believable. Audio plays its part, too, as an ominous soundtrack lays the final piece in the atmospheric scene.

Medium volatile, Primate King may be played on any device, offering stakes from 10 p/c to $/€10 per spin. It seems Red Tiger has been quietly rising RTP in some of its games of late - perhaps evidence of an upward trend, perhaps not. Either way, Primate King possesses a theoretical return value of 96%. The potential is rather big too, and since there is no bonus game as such, max win is possible on a single spin. However, several elements will need to be laid in place to do so, such as wild upgrades and an unlocked sixth reel. Until then, play takes place on a 5-reel, 4-row grid, offering 30 paylines to land wins on.

Clicking our way to the paytable, at the lower end we find card suit royals made out of bones, chains, and whatnot. Premium symbols, meanwhile, include snakes, maps, compasses, and chests of gold. Five-of-a-kind premium wins are worth a payout of 3 to 15x the bet, rising to 6 to 30 times the stake for 6 of a kind when the sixth reel has been unlocked, covered next.

Primate King: Slot Features

Primate King has several things in common with an older Red Tiger slot titled Pirates Plenty: The Sunken Treasure, primarily a 6th reel which can be unlocked to create higher value symbol combinations. Other than that, the game makes extensive use of a variety of wild symbol upgrades.

Occasionally, some symbols will land with a small gold coin displayed on them in the bottom right corner. Whenever these coins appear, they are collected and stored in a meter located to the right of the grid. At certain points in the collection procedure, they trigger the Primate Upgrade feature, of which there are 3 forms;

  • Upgrade 1 turns the regular primate wild symbol into a fully stacked wild.
  • Collect enough coins to unlock upgrade 2, and a random multiplier value is attached to the full reel 1x4 wild symbol.
  • Lastly, upgrade 3 turns the full reel multiplier wild into a sticky version. This sticky primate wild remains in place until it is part of one winning and one non-winning spin. On each consecutive winning spin, its multiplier increases in value. After the first non-winning spin after a win, the sticky big wild reverts back to being un-sticky.

If a primate wild symbol lands but no win occurs, then the Primate Smash feature may randomly trigger. During this one, a gorilla appears on screen to smash the reels, thereby removing all low-paying symbols. Any gaps are filled only by high-value symbols which drop down to plug them. This feature is guaranteed to trigger a win.

Once all 3 primate wild symbols have been upgraded, the progress bar turns into a 6th reel. and remains saved this way on the current bet size and casino. Only high-paying symbols appear on this reel.

Primate King: Slot Verdict

Red Tiger’s tilt toward higher potential, higher RTP games continues with Primate King. Whatever prompted the shift, it's sure to elicit attention from more demanding gamblers. As well as an uptick in stats, the rest of Primate King provides compelling gaming as well. First impressions are good due to the living, breathing jungle environment, and the progress meter adds enticement. If you're ready to take on Kong Jr, then hacking through the bush on a mission to unlock the 6th reel can begin.

Until the grid reaches full capacity, wins are limited to 5 reels as you work to upgrade wilds. It's not an overly lengthy process and you are unlikely to spend masses of time doing so, but it means Primate King demands a bit of extra investment in the beginning compared to other more straightforward games. This aspect might be a little off-putting for those who just want to dip in and out of the jungle rather than set up base camp.

Another possible downside is the lack of a bonus game. Again, not a major issue as Primate King performs perfectly fine without one. It's all about getting on a sweet roll of repeat win respins as the multiplier increases. It is technically possible to win as much as 3,800 times your stake via this method. Clearly, a bunch of high-value respins involving sticky wild multipliers would be required, and what an epic spin it would be. Having to unlock the game's best bits might feel like a chore at first, but there are definite payoffs for doing so, providing fortune plays its part. For a volatile romp through deadly undergrowth populated by angry primates, Primate King is a thoroughly entertaining option.


The lack of a bonus game might be off-putting, but Primate King’s lethal respins feature helps pick up any slack.
