It’s the golden age of dinosaurs and the ones with the biggest teeth were thriving. Released in 2019 Raging Rex is an impressive slot game where the ominous meteorite does wreak havoc but also unearths some wild riches.

Raging Rex has over 4,000 paylines, which can mean quite imaginative winning combinations. The game is also filled to the brim with interesting features, and not all of them are locked away with the free spins which is a nice thing!

This slot is highly volatile with the RTP of 96.34%. The level of volatility is somewhat equal to the risk, so it means that the winnings of the game are scarce and their size can vary greatly. The RTP, short for “return to player” expresses how much of the wagered bets are returned to the players as winnings. But, keep in mind, this is calculated by playing the game for hours, and usually playing just a few spins can result in pretty much anything.

So, let’s travel back in time and see if we can spot the fearsome king of dinosaurs!

Graphics & sound

Raging Rex takes us to the forests of the long-lost world. It’s hot, it’s humid, and giant dragonflies buzz around. There’s a sort of suspension in the air, it’s almost tangible – will it be a verdant meadow behind the trees, or a giant dinosaur, annoyed by your presence?

Raging Rex slot win combination

The green shades of the forest get some colour from the nicely stylized symbols. The best-paying symbols are, of course, dinosaurs. I dare to say that I recognised at least two species in addition to the T-Rex, the one with three horns is Triceratops and the one with the cool crest is Parasaurolophus. But, one can get only as far with their dinosaur knowledge by watching Jurassic Park fifteen times.

The game has some cool animated effects, too. The best, in my opinion, is the Rampage feature where the enraged T-Rex is stomping right at me.

Raging Rex has a nice ambience with exotic (and probably extinct) birds calling and the drums beating the rhythm. I would love to listen to this as it is, but sadly, the sound effects of the winnings and buttons ruin the atmosphere a bit too much. However, I do like the dinosaur roars when they form the winning combination.

Symbols & wins

Raging Rex has six reels, four rows and 4,096 paylines, meaning that the symbols only need to land on adjacent reels starting from the first reel to win. So, the placement of the symbol on a single reel doesn’t matter.

During the basic game, the free spins can be activated by landing at least three meteorites on the reels. On top of that, the basic game has one more feature that can trigger randomly and along with it comes a full reel of wilds.

High-value symbols:

  • 5 x purple dinosaur pay 7.5x your bet
  • 5 x green dinosaur pay 7.5x your bet
  • 5 x blue dinosaur pay 6x your bet
  • 5 x turquoise dinosaur pay 6x your bet

Low-value symbols:

  • 5 x green or purple amber pay 3x your bet
  • 5 x red, yellow, orange or white amber pay 2x your bet

Special symbols:

  • T-Rex / Wild: Substitutes all other symbols, except Scatter
  • Meteorite / Scatter: Three or more meteorites activate free spins


  • Rampage: A random feature that can activate during the base game.

When the mighty T-Rex goes on a rampage it transforms one of the reels to a full-sized Wild. After this, the game activates free re-spins and the T-Rex moves one reel to the left. Re-spins continue until the dinosaur has reached the leftmost reel.

Raging Rex slot rampage

  • Raging spins: Three or more meteorites trigger free spins.

The number of free spins depend on how many meteorites hit the earth:

  • 3 meteorites = 8 free spins
  • 4 meteorites = 15 free spins
  • 5 meteorites = 20 free spins
  • 6 meteorites = 30 free spins

It’s also possible to re-trigger more free spins as follows:

  • 2 meteorites = 5 extra spins
  • 3 meteorites = 8 extra spins
  • 4 meteorites = 15 extra spins
  • 5+ meteorites = 20 extra spins

Before the free spins start, it’s up to the player to choose either Wild hunt or Primal Rage.

  • Wild hunt: During the Wild hunt spins the reels can have extra Wilds with multipliers. The sum of the multipliers can be as high as 234.
  • Primal rage: During the Primal rage spins the giant T-Rex wild lands on one of the reels, and walks around the reels.

Final Thoughts

Raging Rex is an exciting slot with a dinosaur theme. What’s not to like? Especially for dinosaur fans, this game is a guaranteed hit. Not as dark as the Microgaming’s Jurassic Park slot, but sure to be just as fun.

Raging Rex is also a quite typical high-volatile slot. Playing it requires time, moderation and the will to take risks. In my case, I usually play this slot with small to medium-sized bets and play more spins rather than go big with my stakes and spin fewer times.

When triggering the free spins, I typically choose the Wild hunt. Yes, it’s harder to get good wins out of those because winning depends more on how many (if any) Wilds land on the reels. With the Primal rage, one reel is always a giant Wild, so it’s more likely to win something. But, with the Wild hunt, the possibility of several multipliers is more tempting.
