Introduction to Rumble Extinction
Rumble Extinction is a casino slot from Northern Lights Gaming with dinosaurs and a female explorer. The game starts with a voice welcoming you to the jungle, and in the background is a flaming volcano. At first, it may feel a little chaotic, and that’s a feeling that may stick around because you’ll realize that the game is full of features when you start spinning the reels. Some of them, like the Jumbo Symbols that can trigger the Jurassic Bonus respin feature, or the Free Spins with 3x3 Jumbo Symbols, are identical to previous titles such as Panda Bonanza and Polar Bonanza. But Northern Lights Gaming has also thrown in some fresh features in this game. Let’s find out what they are.

The game’s RTP is 96.07%, and the max win is capped at 10,182x the bet. Rumble Extinction has high volatility and a hit frequency of 28.6%, meaning that more than one in four spins is a winner.
Rumble Extinction is set in a tropical place in front of a volcano. On top of the five brown reels are dinosaur bones and a cranium. Fire and lava are flowing from the volcano to the left of the reels, and beneath it is a display of the jackpot prizes. Bird tweets and other animal sounds are incorporated into the dramatic music that picks up speed when you hit the spin button. To make a win, you need to land 3 or more matching symbols on one of the 10 paylines going left to right. The combination must start on the leftmost reel, and the game is available on mobile phones, tablets, and desktop computers.
The lower-paying symbols in Rumble Extinction are J, Q, K, and A. They pay between 0.5x and 2x the bet for a win of 5 symbols. The higher-paying symbols are dinosaurs with green, blue, yellow, and purple backgrounds. They will give you between 2.8x and 8x the bet for a 5-of-a-kind win. The Wild Symbol substitutes all mentioned symbols in making payline wins, but not special symbols.

What features are available in the slot Rumble Extinction?
The features are Wild Symbols, Dinosaur Symbol, Jurassic Bonus, Bone Symbol, Eruption Symbol, Meteor Shower, Collect Bonus, +1 Coin, Free Spins, Pot Bonus, and Feature Buy.
Wild Symbols
Wild symbols appear in the base game and the Jurassic Bonus. They can land on any reel and substitute for all regular symbols to help complete winning combinations on paylines.
Dinosaur Symbol
The Dinosaur Symbol is a type of Scatter Symbol that appears as a Jumbo symbol in the base game, measuring 1x3, 2x3, or 3x3. When a Jumbo Dinosaur symbol appears, it can randomly be nudged into a full 3x3 symbol. Landing the Jumbo Dinosaur fully in view triggers the Jurassic Bonus.
Jurassic Bonus
The Jurassic Bonus is a respins feature that starts with 3 spins on special reels containing only Wilds, Dinosaur symbols, and blank positions. Each unlocked position spins on its own, and any Wild symbol that lands will lock in place. Dinosaur symbols remove regular-paying symbols from the reels in the so-called Splat Bar, starting with the lowest-value symbols. Whenever a Wild or Dinosaur symbol lands, the respin count resets to 3.
Wild symbols can carry multipliers of up to x5. When no respins remain, one Jurassic Spin takes place, using the locked Wilds and any remaining symbols on the Splat Bar. The feature ends after this spin, and all wins are awarded. If multiple multipliers appear on a winning payline, they are multiplied together and applied to that win. During the Jurassic Spin, Wild symbols can substitute for all symbols.
Bone Symbol
The Bone symbol can land on any reel in the base game, and it will add to the Bone Pile above the reels. The Bone Pile can randomly catch up to 3 Coin symbols above each reel. Coins are only collected this way in the base game, and the Bone Pile is saved per bet.
Eruption Symbol
The Eruption symbol is depicted by an erupting volcano. Whenever it lands, it triggers the Eruption feature, which breaks apart the Bone Pile and releases all collected Coins onto the reels. If there are no Coins in the Bone Pile, between 3 and 7 Wild symbols will land instead.
After breaking the Bone Pile, the Eruption symbol turns into a Wild.
Meteor Shower
A Meteor Shower can trigger randomly at the start of a spin, adding Coins to the Bone Pile in the base game. During the Free Spins, Coins are added directly to the three reels in the middle of the grid. The Collect symbol does not appear during a Meteor Shower.
Collect Bonus
Each Coin symbol shows a cash prize and can appear in both the base game and Free Spins. When the Collect symbol lands, all available Coin prizes are collected and awarded. The Collect feature is available in both the base game and Free Spins.
+1 Coin
Landing a +1 Coin symbol increases the Dinosaur Coin Multiplier, which can grow up to x5. This multiplier applies to wins from the Collect feature and resets back to x1 after it is used. When Free Spins are purchased, a random multiplier is awarded. +1 Coin symbols can appear in both the base game and Free Spins, and the Dinosaur Coin Multiplier is saved per bet.
Free Spins
Landing 3 Free Spins Bonus Symbols, depicted by a female adventurer, triggers 8 Free Spins on a special grid with a 3x3 Jumbo Block in the middle. All regular-paying symbols can appear as Jumbo Symbols of 1x3, 2x3, or 3x3 on these reels. Jumbo symbols split into individual symbols when paying.
Pot Bonus
The Pot Bonus is triggered when Lava symbols land on reels 1 and 5. One Pot prize is randomly awarded, which can be a Mini (20x), Minor (50x), Major (500x), or Grand (5,000x) prize. This feature can be triggered in both the base game and Free Spins.
Feature Buy
Activating the Feature Buy for 100x the bet instantly triggers the Free Spins feature.
Final Thoughts on Rumble Extinction
Rumble Extinction features lava, bones, meteors, and oversized dinosaurs. The game has so much on its menu from the start that it sometimes feels almost too much. Features stack on top of features, and while that can be exciting, it can also feel like you’ve seen most of it before. Jumbo symbols, respins, locked Wilds, coin collecting, and flashy bonuses are all familiar territory if you’ve played recent titles like Panda Bonanza and Polar Bonanza. The new additions to this game are the Bone and Eruption Symbols and the Meteor Shower.
However, the new twists, like the Bone Pile and the eruption moments that shake everything loose, add some extra spice and help keep things interesting. Rumble Extinction can be genuinely fun, especially during the bigger bonus rounds where wins can suddenly snowball. The volatility has gone from medium in the mentioned games to high in this adventure, and the max win has been doubled from 5,000x to over 10,000x the bet.
Rumble Extinction from Northern Lights Gaming is a solid, feature-packed slot that plays it fairly safe.
