Raging Rex review
A stacked T-Rex that walks across the screen and leaves re-spins in its wake is the whole idea behind Raging Rex. Play'n GO built this 2019 release on a six-reel, four-row grid with 4,096 payways and a prehistoric setting of meteors and undergrowth. The bonus asks you to choose between two very different ways of using the dinosaur, which gives the game more personality than its medium volatility rating might suggest.
Grid and payways
The layout is 6x4: six reels with four positions each. Instead of fixed lines, the studio counts 4,096 payways, so a win is formed by matching symbols on neighbouring reels rather than along a drawn pattern. With that many routes through the grid, small combinations come together in many shapes, and the real swings come from the features layered on top.
The setting is a cretaceous landscape where dinosaurs roam and meteors fall. Play'n GO lists two named features, Rampage and Raging Spins, and both revolve around the same creature.
Rampage and Raging Spins
Both mechanics lean on the Rex Wild. In the base game it is the source of the re-spins; in the bonus it becomes either a multiplier carrier or a rampage starter on every spin, depending on what you pick.
Rampage
When the T-Rex lands as a Stacked Wild on reels 2 to 6, Rampage mode starts. The dinosaur then moves from right to left toward the first reel, one reel at a time. Each reel it leaves behind awards one free re-spin, so a Rex landing far to the right produces a longer walk and more chances to connect payways.
Raging Spins
Three or more Meteor Scatters start the bonus mode. Before it begins you choose one of two Prehistoric Giga features. Wild Hunt adds multipliers to the standard Rex Wilds, and those can combine up to 243x. Primal Rage instead places a Raging Rex on reels 2 to 6 at random on every spin, which kicks off a Rampage each time.
Choosing between Wild Hunt and Primal Rage
The choice is the most interesting decision the game hands you. Wild Hunt concentrates value in multiplied wilds, with a combined ceiling of 243x, so its outcomes are likely to be uneven: a round without well-placed wilds stays small, while a few stacked multipliers can lift it sharply. Primal Rage spreads the action more evenly, because a stomping Rex arrives on each spin and brings re-spins with it.
Neither option changes the long-run return, which is fixed by the RTP version in use. The pick is about how the bonus behaves, not about better odds.
Five RTP versions and what they cost
This is the point to read carefully. Raging Rex exists in five RTP versions: 96.34%, 94.34%, 91.36%, 87.37% and 84.44%. The matching house edges run from 3.66% to 15.56%. Over $1,000 wagered, the top version keeps about $36.60 on average, while the lowest keeps about $155.60, more than four times as much for the same game and the same graphics.
For a hundred spins at $1, the expected cost is $3.66 at the top setting and $15.56 at the bottom. At $5 a spin the gap becomes $18.30 against $77.80. At $0.20 it is $0.73 against $3.11. The operator decides which version runs, so the headline figure should not be taken for granted.
The volatility is rated Medium. Play'n GO does not publish a max win for it in our data, and no hit frequency is listed.
Sequels and neighbours
Two follow-ups appear in the catalogue. Raging Rex 2 from 2022 and Raging Rex 3 from 2023 both list a 96.2% RTP and a High volatility rating, a step up in risk from the Medium original.
Among 2019 games with similar numbers, Game of Gladiators lists 96.36%, Cash Vandal 96.47% and Perfect Gems 96.5%, all rated Medium. On RTP alone the differences between them are small; the version an operator picks matters more than the gap between these titles.
Pros
- 4,096 payways on a 6x4 grid give plenty of routes for a win
- Rampage turns a single wild into a run of re-spins
- A real choice in the bonus between multipliers up to 243x and a Rex on every spin
- Free official demo available
Cons
- Five RTP versions, the lowest at 84.44% with a 15.56% house edge
- No max win published for the game
- Both sequels move to High volatility, so the family is not uniform
Verdict
Raging Rex earns its place through one strong idea: a dinosaur wild that walks the reels and pays for its walk in re-spins, plus a bonus choice that changes how the round plays. The Medium volatility keeps it approachable. The weak spot is the spread of RTP versions, from 96.34% down to 84.44%, so the same game can cost four times more per $1,000 depending on the setup. Try the free demo and treat any session as paid entertainment.
