Primate King Slot RTP, Details & Wager Limits

The base game action in the Primate King slot takes place on 5 reels, 4 rows and 30 paylines. If you unlock all the wild upgrades, a sixth reel comes into play which opens up the prospect of 6-symbol winning combination.  As usual for a paylines slot, winners are created by landing 3 or more symbols or wilds from left to right in a payline, starting from reel 1.

You can join the Primate King at stake levels that range from between 10p and £10 per spin. To adjust your stake, simply click on the + and – buttons in the bottom left-hand corner. The paytable displays the symbol values in coins. Divide the number by 30 to get the stake value.

The Primate King RTP is 96% which is about average. High variance, the most you can potentially win from a single spin here is 10,000 x your total stake.

Theme – Audio & Design Features – go exploring in the jungle


With a gorilla/jungle theme, the Primate King slot is beautifully designed. The game obviously takes inspiration from the Kong: Skull Island film. Dense jungle and ruined stone buildings and statues form the backdrop to the action.

There’s a dark, somewhat oppressive feel to the visuals here which is matched by a rather imposing soundtrack. You’ll hear the hum of the jungle alongside a thumping, up-tempo backing track. Expect plenty of atmosphere in this jungle trek.

The reels are made up of lower value playing card suit symbols enmeshed in chains and a collection of objects you might expect to see if you were going on a journey of exploration including maps and a compass. The treasure chest full of gold coins is the most rewarding symbol. Land 3, 4, 5 or 6 of these on a payline for a payout of 2.5, 5, 15 or 30 x your total stake.

The mighty gorilla is the wild symbol. This can land on all 5 reels. As usual, the wild substitutes for all paying symbols mentioned.

Primate King is available to play on all devices including desktops, tablets and smartphones. The rather dark design isn’t always the easiest to decipher and it took as a little while to get our eye in. The simple gameplay is well suited to mobile play though.

Primate King Bonus Features

The gameplay in the Primate King slot is rather straightforward. This isn’t a game that’s overloaded with complex bonus feature. Instead, the gameplay revolves around wilds. Those wilds can come with modifiers attached which can really get things moving.

Primate Wild Upgrade feature

You’ll notice that some symbols come with a gold coin attached in the bottom right-hand corner. Each time one of these symbols land, the gold coin is collected in a meter to the right of the reels.

When you have amassed enough coins in the meter, you’ll trigger the Primate Wild Upgrade feature. This entitles you to a wild upgrade. There are 3 of these:

  • Upgrade 1: once triggered, this turns the standard Primate wild into a stacked 1×4 wild. This is a wild reel effectively.
  • Upgrade 2: collect enough coins to fill the second part of the meter and a random multiplier is added to the stacked 1×4 Primate wild.
  • Upgrade 3: the final upgrade turns the wild into a sticky wild reel. This stacked wild remains in place until it makes up part of at least 1 winning combination and 1 winless spin. A multiplier increases with each consecutive win that includes the sticky wild reel. The wild resets to its standard single-symbol size after the first unsuccessful spin following a winning one.

Progress Bar feature

You can keep tabs on how many coins you’ve collected in the Progress Bar to the right of the reels. When you have unlocked all 3 upgrades, the Progress Bar feature comes into play. It turns into a 6th reel which is made up of higher value symbols only. This can give you lucrative 6-of-a-kind wins.

Primate Smash feature

The Primate Smash feature can trigger at random on any spin where a Primate wild lands but no winning combination is created. The gorilla rumbles onto the screen, smashes all the lower value symbols and removes them from the reels. Higher value symbols will drop in and replace the vacated positions. A new payout consideration then follows with the newly added symbols in place.

Primate King Review Summary – all about wilds

The Primate King slot is all about the wilds. On their own, they deliver decent enough action. The action can really motor though when you activate the upgrades and potentially the sixth reel.

The key to winning big comes from the multipliers though. The max win per spin is 900 x your total stake. If the multipliers work their magic, you could pocket 10,000 x stake wins on each spin. The only negative in this game is that there isn’t a Free Spins feature.

However, I found there was no shortage of action though courtesy of the wild upgrades. If you like the jungle theme and simple gameplay, an audience with the Primate King could be for you.

Want more gorilla action? The King Kong Cash slot by Blueprint Gaming is more light-hearted and comes with 9 bonus features. Alternatively, there’s Return of Kong Megaways which is the Megaways version of King Kong Cash and offers 50,000 x stake wins.
