Extinction is a Wild Game Reserve video slot – they are the Odobo’s game studio so you’re unlikely to have ever played any of their games. With 5 reels and 20 paylines, you can play from 20p to £20 a spin. Extinction takes you back into a prehistoric past where dinosaurs walked the earth.

The symbols are represented by classic primeval creatures including the Trilobite, Giant Dragonfly, Compsognathus, Velociraptor, Apatosaurus, Triceratops and Tyrannosaurus Rex. Graphically, I have to say this slot game is simply fantastic and really comes to life in the free spins feature.

The Extinction feature is the free games game and can be triggered by getting 3 or more Free Spins symbols anywhere across the reels. 3 will give you 8 free spins, 4 will give you 12 and 5 of them will give you 20 free spins. The good thing is that you can retrigger more free spins for every 3 Free Spins symbols you get during the feature.

Now, as mentioned, Extinction comes alive in the feature – the backdrop changes from a smoothly landscape to a fiery one. Then you will see fiery fireballs rain down on the symbols to turn symbols into valuable wilds wherever they strike. It’s like a meteor shower which rewards you with wilds. I’ve managed to get 4 wilds on a few free spins before which resulted in a 235 times stake win overall.

I really like Extinction and I found it to be a medium variance slot – you need to be patient as wins tend to be on the smaller end of things in both the base game and free spins feature. I have won over 200 times my stake in the feature a few times though but I’ve had plenty of wilds.

Saying that, I tend to win about 10-20 times my stake more often than not. Extinction is only available to play at bet365 Games and the good thing is that you can play on your mobile/tablet device too. If you like dinosaur-themed slots, you can’t go wrong with Microgaming’s Jurassic Park (which is also available at bet365 Games).
