Rumble Extinction

Rumble Extinction: Slot Overview

The word extinction carries a heavy weight, yet species go extinct all the time and have done so ever since the Earth's been around. In fact, it's been estimated that 99.9% of all species that ever lived on Earth are now extinct. And on that cheerful note, we turn to Northern Lights Gaming's online slot Rumble Extinction, a game which deals in dinosaurs, the animals that ruled the planet for hundreds of millions of years before being wiped off the face of it.

Rumble Extinction's base game takes place in a calm and placid area, where, okay, a volcano smoulders and oozes lava, but not in a species-threatening type of way. The graphics are clear, bright colours abound, and there are enough dinosaurs on screen to make Dr Alan Green happy. Free spins flip the extinction switch, though. The sky reddens, and the volcano erupts, making Rumble Extinction's natural scene a much less desirable place to be. A lot of what's on the screen is pretty standard dino-slot stuff, but Northern Lights Gaming has made it all look quite nice.

Since we're dealing with big lumbering reptiles, Rumble Extinction's gaming area seems a little small to hold them, but it gets the job done. It's a 5x3 grid where 10 paylines evaluate winning combinations. A minimum of $/€0.20 to a maximum of $/€40 may be staked in this highly volatile dino slot, where the highest of the three RTP values is 96.07%.

The regular symbols are four playing card royals, J-A, and four higher-value dinosaur symbols. Five-of-a-kind wins pay 0.5x-2x when made of royals or 2.8x-8x for premium symbols. Wilds appear in the base game and in the Jurassic Bonus. Wilds substitute all regular symbols, and they pay 10x the stake if five wilds create a win.

Rumble Extinction: Slot Features

Rumble Extinction's features are a Bone Pile, Eruptions, Meteor Showers, jumbo symbols, Jurassic Bonus, Collect Bonus, Pot Bonus, free spins, and feature buy.

Features

• The Bone Pile - Landing a Bone symbol in the base game adds it to the Bone Pile above the reels. More Bones means more layers are added to the pile. The Bone Pile catches coins in the base game only, and it is saved per bet.
• Eruption Symbol - The Eruption symbol may appear in the base game. Landing one triggers an Eruption, which destroys the Bone Pile, causing any coins in the pile to land on the reels. If no coins are collected in the Bone Pile, wilds land instead.
• Meteor Shower - A Meteor Shower may trigger at random at the start of a spin. In the base game, it adds coins to the Bone Pile. During free spins, coins are added to the middle three reels.
• Dinosaur & Jumbo Dinosaur Symbols - A special Dinosaur symbol may land in the Jurassic Bonus. The Jumbo Dinosaur symbol lands on the middle 3 reels as a 1x3, 2x3, or 3x3 symbol. The 1x3 and 2x3 symbols can nudge to a 3x3 symbol.
• Jurassic Bonus - Landing a 3x3 Jumbo Dinosaur symbol triggers this bonus. It begins with 3 respins where only wilds and Dinosaur symbols may land. They reset the meter when they do. Wilds are held and increase wins by up to x5. Landed Dinosaur symbols knock out pay symbols from the Splat Bar. When no respins remain, reels spin with the held wilds and any symbols left on the Splat Bar.
• Collect Bonus - Hitting +1 Coin symbols increases the Dinosaur Coin Multiplier up to x5. This occurs in the base game and free spins. The multiplier is saved per bet. Coin symbols have a cash prize value of 0.2x to 20x. Hitting a Collect symbol on the rightmost reel awards cash prizes on the reels.
• Pot Bonus - Landing a Lava symbol on the leftmost and rightmost reels in the base game or free spins triggers this bonus. One Pot Prize is randomly awarded, which could be the 20x Mini, 50x Minor, 500x Major, or the 5,000x Grand.

Free Spins

Hitting 3 free spins on the leftmost, middle, and rightmost reels in the base game awards 8 free spins. Symbols can appear on the three middle reels as 1x3, 2x3, or 3x3 Jumbo symbols. Jumbo symbols split into individual symbols to pay.

Feature Buy

Players may buy the free spins feature for 100x their bet, and a random multiplier is awarded before the reels spin.

Rumble Extinction: Slot Verdict

While a single species going extinct is sad, mass extinctions are the really scary ones. The biggest was the Permian-Triassic extinction, also known as the Great Dying, which is said to have wiped out most species on Earth. That's hardcore. Fortunately, the only thing which could really go extinct in this game is an unlucky bankroll going up in smoke. Rumble Extinction does lay out quite a few features to potentially prevent that from happening. Many are common extras, such as coin collection and big symbols, but there are effects which are quite unique to Rumble Extinction.

One of the most unusual components is the Bone Pile sitting on top of the reels, gathering coins when Meteor Showers rain them down onto it. Later on, when the volcano erupts, anything caught up in the Bone Pile (or wilds if there are no coins) falls onto the reels. It's still collecting coins, but the buildup and motions are a bit different. Plus, when the multiplier is growing at the same time as bones are loading up, well, some gamblers may enjoy that sort of suspense. The Jurassic Bonus is another entertaining diversion which squeezes quite a lot into a relatively small side feature - symbol removal, wild symbol stacking, etc. On the financial side, Rumble Extinction's winning potential might not be a plodding diplodocus, but its 'win over 5,000x' feels like a good fit.

So, while a lot of Rumble Extinction might be regular coin collection, jackpot stuff, Northern Lights Gaming has played around with delivery systems, meshing mechanics with the theme to produce a game that some gamblers may enjoy playing palaeontologist to.
