Raging Rex (Play’ n Go)


At the beginning of January 2019, the casino software developer Play’n Go released a new title based on the theme of the prehistoric world (here it goes about dinosaurs and not about Egyptians with their pyramids). Raging Rex – is a high volatile 6*4 video slot, which offers 4096 play lines. RTP (return to player) is 96.34%. The minimum bet is 20 cents per spin that undoubtedly pleases low rollers.

Design and layout

The Play’n Go holds to the traditions. That is why the game interface is similar to many other slots from this provider. To place a bet, you don’t need to struggle with coin value and lines, just choose an appropriate bet and press the spin button.

Microgaming fans may smell a rat that the idea of the Raging Rex slot was “borrowed” (slots Jurassic Park and Jurassic World) as well the same story was with the Book of Dead slot (the original one is Book of Ra powered by Novomatic).

Let us start with a layout. At first sight, it is quite apparent: the action takes place in the impenetrable jungle where a danger behind every tree is. If you do not want to be a dinner for a raging T-Rex, keep your ears open!

For Jurassic Park and Jurassic World developers used original film shots and characters. From our perspective, such slots fight a losing battle from the very beginning. We usually see main characters, a handful of opening frame videos and an undistinguished soundtrack.

Notwithstanding the success of the Jurassic World film, the slot couldn’t make a name for itself. It is because there is no highlight or characteristic feature in comparison with others. Therefore, Play’n Go developers tried to think up their own symbols. On the game reels, we see premium symbols with the highest paying and low-paying ones. Low win symbols are some insects and for lines with velociraptor, dilophosaurus, triceratops, and parasaurolophus you may get more.

Visual artists decided to play on double contrast and create bright-coloured symbols on the background of dark jungle vs stylized symbols and quite “real” jungle forest. Probably that makes sense. However, it is still unclear why they didn’t pay enough attention to the main character of this story – T-Rex. We were utterly disappointed seeing stacked symbol. If you take a closer look, it seems that its head and front paws are isolated from the body. The animation is also bad, looks clumsy. A dinosaur in the slot Jurassic World, by the way, looks much more realistic.

Despite some these shortcomings, the graphics, in general, is better than in a similar slot Jurassic Giants powered by Pragmatic Play.

In slots as well as in video games visuals and sound should be an integrated completely, but unfortunately, we do not see this harmony here. This is not that game to switch off your favourite music and to switch on slot sounds. If it were not growling T-Rex, it would be nothing in common with the prehistoric world. Here we only have some sounds mixed with a ring of coins. Developers of the Great Rhino slot (Pragmatic Play) succeeded much more in making a good soundtrack. Full-fledged soundtrack. While hearing you imagine yourself being somewhere in the savannah where rhinos are running under the glaring sun.

A “competitor” from Microgaming the Jurassic Park slot also didn’t attract adoration. Such approach: some soundtrack from the original movie + some dinosaurs growling + ring of coins didn’t provide its value.

Features and bonus games

Now let us find out how it works and which exciting features developers hide. There are two main symbols wild – T-Rex and scatter – meteor, we also see here the presence of multiplier. The wild symbol doesn’t have its own value and can substitute for all symbols except scatter. Wild lands on reels 2-6. There is no bonus game here but two Free Spins modes.

If you get 3, 4, 5, or 6 scatters on reels it triggers a Raging Spins Feature. You will spin 8 times (3 scatters), 15 times (4 scatters), 20 times (5 scatters), and 30 times (6 scatters) respectively. You are to choose between Wild Hunt and Primal Rage mode before Free Spins get started.

Wild Hunt – multiplies a winning combination by 2x and 3x thanks to additional Wild symbols. These symbols land on reels 2-6. If you manage to get several ones, then their multipliers are multiplied and the maximum might be 243x.

Primal Rage – during this Free Spin mode, a stacked wild symbol of T-Rex randomly moves across the screen with each spin.

During Free Spins in both modes scatter symbols may appear, it means you get additional free spins. Theoretically, their number is not limited.

  • 2 scatters – 5 free spins,
  • 3 scatters – 8 free spins,
  • 4 scatters – 15 free spins,
  • 5/6 scatters – 20 free spins.

One more interesting thing is a Rampage feature. It triggers randomly on reels from 2 to 6. The symbol of huge, furious tyrannosaur moves right to the left up to the 1st reel. Number of free spins during this feature depends on a reel on which the symbol appeared. For example, you will get 5 spins if T-Rex starts moving from the 5th reel.


The online slot is playable across all devices: desktop, mobile and tablet devices. This is a big plus. It is also well optimized, no bugs or glitches during playing. At the present stage of gambling industry development, not all providers could boast of excellent slots’ optimization.

Choosing a free spin mode is not a brand-new feature (Wild Hunt – Wilds with multiplier 2x / 3x or Primal Range – a stacked T-Rex symbol). Jungle Spirit (NetEnt), Immortal Romance (Microgaming), Moon Princess (Play’ N Go) and other slots come to mind straight away. There is plenty of slots with extra spins, no need to go into detail. The difference is only in graphics. This feature adds more spins, increasing your chances for a big win. Who doesn’t want to hit the jackpot?

On the negative side, a multiplier on a win 2x / 3x is available only in Wild Hunt. For example, in the Jurassic Park slot from Microgaming during free spins called Gyrosphere Valley, there is a multiplier up 10x.

Surely it is not the best slot from the Microgaming creative kitchen but notwithstanding it is worth mentioning regardless of some shortcomings. The team of developers made a try to create a new, one-of-a-kind product and not to take a movie as a basis and tried to repeat its success.
