Primate King Verdict
Primate King uses a new concept by Red Tiger where you save up for a better playing experience. The more you play, the higher your potential wins. This essentially means you trade the classical free spins bonus for a sticky increasing multiplying wild and a sixth reel that brings you extra wins. It works wonderfully well, and combined with the theme, Primate King will keep you hooked for hours.

Theme and Atmosphere
Primate King is essentially a King Kong slot without the license. Thankfully, it doesn’t feel or look cheap. The sounds, visuals, and theme work together like a charm, and all fit into the ‘Adventure Island’ thema. Skulls and gold coins are supplemented with the occasional gorilla roar. It’s no jaw-dropping slot that belongs in the museum of video slots, but a great production nonetheless.
Gameplay and bonuses
The game revolves around five reels and four rows. You combine three or more symbols on up to thirty winlines. The wild helps you here in two different ways. First, it replaces other symbols in a combination, but it also drives the special mechanism in this slot.
Some symbols appear with a gold coin. If you combine the gold coin with a wild, they contribute to the meter that has taken up the place of the sixth reel. There are three milestones to save up for, with each milestone upgrading the wild.
The first upgrade turns the single-symbol wild into a wild reel. Secondly, you receive a random multiplier on every wild reel. The third upgrade is a double whammy: it makes the random multiplier wild reel sticky and replaces the meter with the sixth reel (where only high symbols appear).
This last sticky multiplying wild remains as long as you get winning combinations. Each winning combination adds a factor to the multiplier, creating a chance to create a sequence of increasingly higher wins.
Each upgrade lasts the remainder of your playing session, which means that wins get higher as you play longer. The multiplying sticky wilds essentially take the place of the traditional bonus rounds. There is no such bonus round in Primate King.
Math
I’ll be honest, the math model is fascinating to me. You start off with a normal wild, and play towards a sticky multiplying wild reel that keeps increasing with every subsequent win. After a while, wins are higher than when you first start playing. Nevertheless, the game always feels balanced. One downside is the relatively lox max win of 3,800x, especially considering the maximum bet size of $20 per spin.
Editor’s discretion
Primate King is a great slot, which is all the more impressive since not that much happens on the reels. There are no scatters, no bonuses, and you’re just collecting gold coins for improved wilds. Yet the slot still feels thrilling and has big wins scattered throughout to keep you afloat. This isn’t a hit and run slot by any means, but it’s a slot you’ll want to keep playing.
Alternative slots
Pirate’s Plenty Megaways follows a similar pattern where the game gets more rewarding after you’ve played a while. It also offers a great atmosphere.
