Primate King is a Red Tiger Gaming slot with 6 reels, 4 rows and 30 paylines. The game has a stated RTP of 95.66% and high volatility, with stakes from €0.10 to €50.00. In the demo version, players can play for free and practice before playing for real money.
The main feature centres on Gold Coins, which can appear on the reels and feed the Primate Wild progress bar. As the bar fills, the Wild develops through three upgrades: a stacked 1x4 form, then a random multiplier, then a sticky Wild that can remain on the reels for several spins after a win.
Once all upgrades are unlocked, the progress bar changes into a sixth reel containing only high-paying symbols. Primate King also includes a bonus mode, while the Wild symbol substitutes for all paying symbols during regular play.
