Primate King slot review

Last Update: 13.08.2021. Author: SlotCatalog.

The damp jungle setting of Primate King reminds us of the Monkey Island computer game franchise, with a mysterious gorilla mouth cave on the left-hand side, and human skulls on the right. Creating visually pleasing games is no problem for Red Tiger, but they have a knack for messing up the math model. It’s far from the worst we’ve seen this time, however.

With no bonus round to look forward to, you do get a sense of progress as you upgrade the regular wilds to stacked wilds, multiplier stacked wilds and finally to sticky stacked wilds with increasing winning-streak multipliers. This also unlocks a 6th reel, increasing the max 5-of-a-kind win from 15x to 30x your stake. The 3800x max win is still thoroughly multiplier dependent though, as the highest non-multiplier single spin win is 900x your stake.

Primate King slot Features

Random symbols will land with small gold coin icons attached, and these are collected in the Upgrade meter on the right-hand side. There are 3 tiers on the meter, and these affect the wilds that land in the following ways:

  • Tier 1 - turns the regular 1x1 primate wild into a fully stacked 1x4 wild.
  • Tier 2 - adds a random multiplier to the fully stacked wild.
  • Tier 3 - makes the multiplier wild reel sticky until it’s been part of both a winning and a non-winning spin. The multiplier increases in value per consecutive winning spin, and it becomes non-sticky after the first losing spin after a winning spin/streak.

Whenever you land a primate wild without winning, the Primate Smash feature might trigger. You’ll see a gorilla smash the reels to remove all low-value symbols, and the gaps are filled with premium symbols dropping down from above. This feature comes with a win guarantee.

When you’ve reached tier 3 on the Primate Upgrade meter, the progress bar transforms itself into a 6th reel. The 6th reel remains in place as long as you play at the same casino with the same stake. You will only land premium symbols on the unlocked 6th reel, and all wilds that land anywhere will be tier 3 wilds.

The 200 Spins Primate King slot Experience

The 3-minute highlights video starts when we’re close to reaching tier 2 on the Upgrade meter. It happens almost immediately, but only a small win comes from the 2x stacked wild we get. Several larger payouts are landed a bit later however, and overall we had a pretty good time testing this game.

Review Summary

Red Tiger has done a clever thing with Primate King. Once you’ve upgraded the wilds to tier 3, and thus unlocked the 6th reel, you have a strong incentive to return to this game again and again. Just make sure to play at the same casino, and don’t change the stake, and the game will fire on all cylinders forevermore.

The lack of a proper bonus round might bother some players up front, but it’s not sorely missed when winning streaks keep building the stacked wild multipliers. It doesn’t take all that long to fill the Upgrade Meter either, so we’re not talking about a massive commitment here. The 3800x potential is certainly solid enough, but you do get the usual lower-than-average RTP, as well as customizable RTP ranges.


  • 3-tier wild upgrade meter
  • Unlocks 6th reel when filled
  • Random low-value symbol removal
  • Win up to 3800x your stake


  • Highest RTP is 95.66 % (RTP ranges)
  • Max bet is only £10 per spin

If you enjoy Primate King slot you should also try:

Pirates Plenty The Sunken Treasure - is a Red Tiger release that’s thematically different, but it also comes with a 6th reel to unlock. This is crucial, as it allows you to trigger wild multiplier reels up to 5x in the base game. Low value symbols can turn wild in the bonus round, for payouts up to 5,000x.

Silverback: Multiplier Mountain - is a volatile gorilla slot from JFTW, and it comes with 6 reels, 4 rows and 4,096 win ways. You’ll climb a multiplier mountain during the bonus round, where each win gives you 1 extra free spin. This can lead to 25,000x your stake payouts.

Gorilla Kingdom - is a visually pleasing NetEnt jungle game, and you can place bets up to a solid £350 per spin. The volatility is casually medium, and you can win up to 4,096x your stake in the transforming symbols bonus round.
