Jurassic Island is a five-reel, 25-payline slot from Ash Gaming (a Playtech company) based on the theme of – you guessed it – dinosaurs. With three free spins features plus another bonus round where there are some juicy prizes on offer, there’s plenty to discover in this world. For the full lowdown on Jurassic Island and how to play, read our review.

Jurassic Island online slot shouldn’t be confused with Jurassic Park, which is based on the classic film of the same name. This game grabs your attention straight away with an introductory animation showing an erupting volcano and presenting the four bonus features of the game. We also see the two main characters – a hunter and a raptor. They have further significance, which you’ll find out about later...

The prehistoric theme becomes even more evident once you open up the game. There’s a rhythmic, beating soundtrack that doesn’t get repetitive, along with funky animations when you get a win. Both the audio and visual elements are crisp, right down to the sounds of dinosaurs and birds in the background. The reels are laid out like slabs of rock and have numbers at the side denoting the 25 paylines. The symbols include card ranks from ten to ace, which are depicted with dinosaur bones. Then there’s a triceratops skull, as well as four other types of dinosaurs: pterodactyl, velociraptor, raptor and parasaurolophus. The last is the highest-paying icon, awarding you 1,000 times your stake if you land five on a payline.

As well as the ten main base-game symbols there are two extras. First, the raptor that’s seen in the background also appears on the second, third and fourth reels as the wild and expands to fill the reel if doing so results in a win. The raptor appears fairly regularly and can deliver some decent returns. The other additional avatar is the hunter. He acts as the scatter and if you land three or more of him anywhere on the reels, you get to select from one of four features:

• Multiplier Free Games - Three, four or five scatters will give you ten, 15 or 30 multiplier free spins. During the feature, two, three, four or five scatters will retrigger the feature giving you three, ten, 15 or 30 additional free spins respectively, and all wins in the feature are trebled.
• Carnivore Free Games - The number of free spins and additional free spins you get depends on the number of scatters you land in the same way as the Multiplier Free Games feature, but the difference in this one is that only high-win symbols appear.
• Raptor Free Games - Three, four or five scatters will give you 16, 24 or 40 free spins. During the feature, two, three, four or five scatters will give you three, 16, 24 or 40 additional free spins, and this feature benefits from stacked expanding wilds.
• Hot Shot Hunter Bonus - This bonus game involves shooting down dinosaurs using a crosshair. Three types of dinosaurs will move across the screen one at a time, and how much you win depends on the type of dinosaur, how many of them you hit and the multiplier you’re given. You can win up to 180 times your stake for hitting six white dinosaurs.

The theme of this slot might be prehistoric, but play it and you’ll find the action and display bang up-to-date.
