Primal Rampage Slot by Play'n GO

A giant gorilla holds the 3x3 grid in its fists, chains wrapped around a metal frame set against burning city blocks and overturned military vehicles. The base game runs on just three reels with way wins, but the ape adds a collection layer that drives everything. Rage Symbols land on any reel, and the gorilla grabs them. Collect three and the Primal Wheel spins, offering fixed prizes from Mini (10x) up to Grand (1,000x) or entry into one of two free spins modes. If only one or two Rage Symbols appear, the ape still pockets them for a random chance to force the wheel - so even partial collections keep pressure on the trigger.

Kong Quest starts with 8 spins on an expanding grid that randomizes each round between 3x3 and 3x8. At full stretch, eight symbols per reel multiply the ways count and push payline hits into territory the base game can't reach. Vault Bonus symbols during Kong Quest hide extra free spins behind their prizes, so cracking one open might extend the round instead of just paying out. King Spin also starts at 8 spins but stays locked at 3x3. The tradeoff: every Vault on screen unlocks instantly, and the ape smashes the reels repeatedly to upgrade vault tiers. Vaults climb from x1 through Mini, Minor, Major, Mega, all the way to Grand. Double-value tiers exist too - MEGA2X, MAJOR2X - paying twice their base amount.

The Wild only appears on reel 2, carrying multipliers from x2 up to x100. That x100 Wild is rare but it applies to any combination passing through the center reel, and on a 3x8 Kong Quest grid with enough matching symbols stacked, one hit with a high multiplier reshapes an entire round. Symbols lean into the urban destruction theme - tanks, army helmets, ammo crates, and dog tags in purple and olive tones, with metallic card royals filling out the low end. No buy bonus, so the Primal Wheel fires only through Rage collection or luck.
