Review of Extinction Mobile Slot by Odobo

Extinction Feature ImageHere’s a slot that is set 65 million years ago, when dinosaurs roamed the Earth. In fact, our timeline gets a little more specific. We’re talking about that exact moment when dinosaurs died out (Google informs me that this event is termed as the “K/T extinction event”).

The cause of dinosaurs’ extinction remains a mystery to this very day –  it could have been climate change, diseases, volcanoes and or even a sudden death of plants. Anyway, this slot by Odobo has a theory: dinosaurs were wiped out by meteorites! This slot illustrates the entire event: meteorites (Free Spins) crash into the game boards; the dinosaurs turn into fossils (Wild Symbols). It’s a disaster for the dinosaurs, but good news for slot players!

The Extinction slot is your average slot. It has 5 reels and 20 paylines. Spins range from 20p to £40 per spin, which will fit comfortably in any players’ budgets.

There are quite a variety of dinosaurs featured on the reels. You can check the paytable for all the different names and payout values; there are Trilobites, Giant Dragonflies, Compsognathus, Velociraptors, Apatosaurus, Triceratops and Tyrannosaurus Rexes. You’ll feel quite knowledgeable after reciting these names out loud. You want to capture the more carnivorous dinosaurs such as T-Rexes and Velociraptors for bigger wins.

Extinction Free Spins Gameplay

The game quotes a Return to Player percentage of 96.34%. Extinction is a medium-variance slot. The wins are generally small during both the base game and free spins feature; these wins are about 10-20x my wager. Then, a large win appears randomly! I have won over 200 times my stake once or twice.

What’s special about the Extinction slot are the free spins. The free spins symbols are illustrated by fiery meteorites. It’s supposed to portray that moment in time when dinosaurs were wiped off the face of the Earth. Anyway, here’s how many free spins you stand to win:

  • Get three Free Spins symbols and win 8 free spins
  • Get four Free Spins symbols and win 12 free spins
  • Get five Free Spins symbols and win 20 free spins

These free spins symbols can appear anywhere on the reels, in no particular order or payline. If you’re especially lucky, you can also retrigger free spins during the free spins rounds.

Extinction Wild Symbols Information

This slot game really come to life during the Free Spins rounds. The backdrop suddenly bursts into flames and it starts raining fireballs. Whenever a fireball strikes a dinosaur symbol, the symbol turns into a Wild fossil. As any slot player knows, Wild symbols dramatically increase the chances of winning. This meteor shower isn’t a wimpy one either – I got an average of four wilds during each free spins round.

The Extinction Slot is programmed using the latest HTML5 technology. What this means is that the game can be played on all devices – mobile, tablet and desktop browsers; with no app or plugin required. The graphics are in HD too, so the game will look nice on the latest iPads. I just had to compare the dinosaurs in Extinction with those in Microgaming’s Jurassic Park slot. The Jurassic Park guys won; well, of course they did, those dinosaurs appeared in a blockbuster movie.

Unique Features

Extinction is produced by this company called Odobo. Odobo’s platform includes some really premium-quality slots. You should check out this one called Castle Builder – you’ll collect bricks with each spin of the slot and build an actual castle! Extinction is one of their less innovative slots, conceptually at least. However, it shares the same stellar math model and HD graphics that come with all of Odobo’s productions.

Droid Slots' Stamp of ApprovalThe game’s marketing copy promised “meteoric payouts” and “cataclysmic free spins”. While it’s not quite that profitable, Extinction is still a great slot. The bonus features occur often enough to hold your attention, and the payouts are large enough for you to slowly build your bankroll. I’d give it four out of five stars.
