Primate King Slot

Compared to Red Tiger’s other animal slots, the Primate King slot prioritises atmosphere over variety, focusing on a grounded aesthetic with fewer flashy elements.

Symbols, Features, and How to Play

The Primate King is an online slot game that attracts players with its progressively evolving features, moving away from conventional free spins or typical bonus rounds. Its visibility lies in a unique wild upgrade system, which gradually improves as players advance through the game.

Symbols

The Primate King slot game divides its symbols into three groups:

• Low-value symbols: 10, J, Q, K, A
• High-value symbols: Scroll, Map, Compass, Treasure Chest
• Special symbols: Primate Wild, Gold Coins.

The symbol layout is tight. There’s a visible gap between low- and high-tier values, which helps keep the slot’s volatility steady. During test spins, I saw frequent coin drops that made each round feel useful, even without a win.

Bonus Features

There are no scatter-triggered free spins. Instead, bonuses in Primate King revolve entirely around Wild symbol progression:

• Upgrade 1: Wild becomes a stacked 1×4 symbol.
• Upgrade 2: Wild gains a multiplier.
• Upgrade 3: Wild becomes sticky and keeps winning until one dead spin follows a win streak.

When all three upgrades are activated, the progress bar evolves into a sixth reel that exclusively features premium symbols, significantly increasing the potential for maximum wins.

Another feature is Primate Smash, which is triggered when a Wild appears but fails to generate a win. In this case, the gorilla intervenes by smashing the reels, eliminating all low-value symbols and ensuring a payout composed entirely of premium ones.

A further gameplay layer includes Jackpot mechanics:

• Progressive Jackpot: Accumulated through a percentage of all stakes, with wins possible at any time. Winning odds rise with higher stakes. The prize resets with a seed fund after each win.
• Time Jackpot: Guaranteed to pay out before a set time. The closer to the deadline, the greater the chance of triggering it.
• Dynamic Jackpot Allocation: Only stakes above £2 contribute to the progressive jackpot. Time jackpots apply only to the first £2.
• Daily, Hourly, and Booster Jackpots: Feature fixed minimum starting values – e.g., £500 for Daily Cash Booster, £2,000 for Daily Jackpot, and £100 for Hourly Jackpot.

These jackpots activate randomly and do not require any additional actions apart from spinning. They are not influenced by multiplier effects. Players need to note that progress and upgrades are linked to specific stake levels and are saved within each stake band separately.

Now onto the essentials: layout, how to play, paylines and RTP.

Technical Layout, Speed, and Bet Options

The Primate King slot machine features a 5×4 grid with 30 fixed paylines. As you progress through the Wild upgrades, a sixth reel is unlocked on the right side. While the number of lines remains fixed, you have the flexibility to adjust your total stake using the +/- buttons. Betting starts at £0.10, with a maximum wager of £2 per spin.

The interface is user-friendly, with the control panel conveniently located at the bottom of the screen. Key functions, such as spin, autoplay, and paytable, are easily navigable. The autoplay feature includes customisable options such as setting the number of spins, stopping on a win, or halting after a specified loss.

The RTP is 92.67%. You should review the paytable for each game version, since we found a variant during testing with an RTP of 95.66%. The game’s high volatility makes it suited for players who are prepared to invest time and see their efforts pay off as features unlock.

Controls responded fast throughout my test session. No delays, and autoplay didn’t skip or freeze. The betting range is tight, so this slot suits lower-stakes players. If you’re looking to try a slower-build strategy, this game rewards consistent play once the upgrades kick in.

Feedback on Gameplay and Bonuses

Our team tested Primate King thoroughly to evaluate its core features, bonus progression, and payout potential. Here’s what we noticed:

I didn’t trigger the jackpot or Smash feature often, but I did manage to unlock all three Wild upgrades after about 150 spins on £1 bets. The stacked Wild and sixth reel improved payouts noticeably. There’s no free spins bonus, so you’ll need to lean into the progress-based strategy – treat it as a long-game slot where higher stakes may improve your odds.
