Raging Rex

Play'n GO sets Raging Rex in a prehistoric forest patrolled by a Tyrannosaurus, running the action across a 6-reel, 4-row grid with 4,096 ways to win. It's one of several dinosaur-themed slots on the market, and the presentation - dragonflies drifting past a background waterfall, dense green foliage - keeps to fairly conventional territory for the subject rather than pushing the visuals in a new direction.

Low-value symbols are six insects preserved in amber, including a scorpion and a spider, while the premium tier moves through four dinosaurs - Triceratops, Parasaurolophus, Dilophosaurus and Velociraptor - with the Velociraptor paying 7.5x the stake for five of a kind, the richest of the standard symbols. The T-Rex acts as the wild, substituting for everything except the scatter.

The Rampage feature triggers in the base game whenever a full stack of T-Rex wilds lands anywhere from reel 2 to reel 6. That stack turns sticky and then steps one reel to the left with each subsequent spin, so a stack that first appears on reel 6 gets the most mileage - five respins as it walks its way across the grid. Rampage itself cannot retrigger.

Scatters come in the form of meteors, and landing three, four, five or six anywhere on the reels awards 8, 15, 20 or 30 free spins respectively. Two or more meteors turning up during the bonus add further spins on top, so a run of good luck can extend the round considerably. At the start of the round, the choice is between two paths: Wild Hunt strips out the stacked wilds in favour of x2 and x3 multipliers attached to individual Rex wild symbols, which combine when more than one appears in a winning line for totals up to x243; Primal Rage keeps the walking stacks from the base game active throughout the bonus instead, with a fresh stack appearing on reels 2 to 6 on every spin.

Play'n GO publishes Raging Rex at five different return settings depending on the operator - 96.34%, 94.34%, 91.36%, 87.37% or 84.44% - with volatility rated 8 out of 10 on the studio's own scale. Bets run from 0.20 to 100 per spin and the maximum payout is 5,000x the stake, reached most reliably through a well-multiplied Wild Hunt round rather than the base game's Rampage respins. Between the walking wild stacks and the two-path bonus choice, Raging Rex spends most of its energy on variations of the same wild-stacking idea rather than introducing an unrelated second mechanic.
