Primate King Slot Review

Venture to a mysterious tropical island with the Primate King slot machine. A giant ape rampages across 5 reels and 30 paylines, along with gold coins that you collect to upgrade features. The wild gorilla becomes a stacked wild, multiplier wild, then finally, a sticky multiplier wild symbol as you gather coins.

Unlock a sixth reel and you can win up to 3,800x your bet, or 76,000.00 at the highest stake. Primate King is a highly volatile beast, where the average return to players is 95.66%. Play it on a PC, Android, iOS, or Windows mobiles at our favourite online casinos.

How to Play the Primate King Slots Game

The fantastic graphics take you to the heart of Skull Island, where an ape-shaped cave sits to one side of the reels and skulls on sticks decorate the other. Twisted vines cover a bamboo frame around the reels, and symbols consist of a compass, snake, treasure chest, and map. These high-paying objects are joined by lower-value card suit symbols, plus bonus images of a mighty gorilla, and apes on gold coins. It looks great, although the traditional slot-style soundtrack doesn’t quite match the visuals.

Like other games in the Red Tiger range, Primate King features easy to use controls. You click the Stake button to reveal options from 0.20 to 20.00 for each spin, and a click on the Auto tab next to it gives you the option to set the reels spinning on their own for up to 100 times.

The Pays button below shows you how much you win from matched symbols across any of the 30 lines. The sequence needs to start from the left and symbols must be on adjacent reels to count. The treasure chest pays the most, at between 75 and 900 coins for your 30-coin stake.

Primate King Slots Game Wild Collection Feature

The gorilla is a wild symbol, so he can substitute for any other to complete wins. Occasionally, he smashes away lower paying symbols on a losing spin. This Primate Smash bonus sees higher value symbols drop from above to fill the gaps and you are guaranteed a win from the new mix of more valuable themed icons.

Gold coins overlay random symbols and these collect in a bonus reel meter to the right of the main reels. This gradually fills to permanently unlock improved wild symbols, although be aware that changing your bet level clears away the progress made so far.

At level one, the ape becomes a stacked wild symbol that fills all 4 rows of any reel he lands on. At the second level, a random multiplier is added to any wins made with the help of stacked wilds. This can be anything up to 4x.

The most valuable wild is a sticky stacked multiplier symbol. The meter unlocks to become a sixth reel, and the wild stays on the reels as a multiplier increases for each win in a sequence. It only resets and removes the wild on a losing spin.

Maximum Wins, Average Returns, & Volatility of the Primate King Slot Machine

With the perfect blend of treasure chest symbols and wild multipliers, you can scoop a prize of 3,800x the bet, which equals 76,000.00 when you play with 20.00 per spin. That’s a lot less than many other high volatility games like this, while the average payback percentage is a little low, at 95.66%.

Our Primate King Slot Rating

This is a great-looking game with an exciting topic. The average payback percentage is slightly below the 96% or more that we prefer, and the maximum stake of 20.00 will be too low for some. There’s also no free spins bonus round, but that’s offset by the valuable wild upgrade feature.

Permanently improved stacked, sticky, and multiplier wild symbols can lead to plenty of decent wins, and the Smash feature, which turns a losing spin into a guaranteed winner is a nice extra touch, Don’t forget that changing your bet removes all wild upgrades, and of course, you need to play the Primate King slot at the same casino to keep the benefits.

Make sure that casino is one of the best Red Tiger sites featured here, where you can claim a fantastic no deposit welcome bonus package when you sign up.


The Primate King slot is a 30-line game where you win by matching symbols from the left side across any payline. The symbols need to be on connected reels, but the wild gorilla helps by stepping in for others if it can then complete a combination.

Yes, it is. The high volatility of the Primate King slots game means that you may see several losing spins, followed by comparatively high prizes. On average, low volatility games can pay lots of smaller wins, while medium variance games are in between these formats.

Gold coins collect in a meter and once you have enough, wild gorilla symbols permanently upgrade. The basic wild becomes an expanded wild symbol, then an expanded wild with multipliers, and finally a sticky expanded wild symbol.

There’s no need to download the Primate King slot to play. It’s accessed at the best online casinos via a browser on desktop or mobile platforms. Some casinos offer the option of downloadable apps or software, but it’s not a requirement.

The Primate King slot follows an exciting topic and uses top-quality graphics to bring an adventure to online casinos. It has an unusual wild upgrade feature that helps it to stand out from other games, and there’s even a random feature that turns losing spins into winners.

Gorillas seem particularly popular with both game developers and players, and there are many similar slots. The Gorilla Kingdom slot from NetEnt is a good choice, and it comes with a free spins bonus round where you collect masks to activate extra bonus games.

You can’t play the Primate King slot for free, but if you join a recommended casino and claim their welcome bonus offers, you can play it using their funds and not yours. UK Gambling Commission rules ban free online casino games in the country.

Casinos will occasionally offer special promotional codes that let you play their games with extra bonuses. You’ll find the latest offers here at, although we can’t promise that the Primate King slot will be promoted.

Yes, it is. The Primate King slot machine works on iOS, Android, and Windows mobiles. All you need is a Wi-Fi or mobile network connection to play the game on your favourite phone or tablet, and of course, it has all of the same features as the desktop version.

Red Tiger released the Primate King into the virtual jungle of online casinos on 23rd April 2021. Cut through to the best sites and follow our links to the top games and bonuses at our recommended casinos.
