Jurassic Island is a Playtech-powered video slot which comes with 5 reels and 25 paylines. Available on all compatible devices such as iOS, Android, laptops and PCs from 25p to £125 a spin, this pre-historic, dinosaur themed game has 4 bonus features in total with 3 of them giving you free spins where you can choose your level of variance.

With cartoon style graphics, the imagery is sharp and has an intrepid hunter and dinosaurs as the backdrop to the reels. Symbols include dinosaur bone styled playing cards (A, K, Q, J and 10), triceratops skulls and 4 dinosaurs (Parasaurolophus, Raptor, Velociraptor and Pterodactyl). The Parasaurolophus rewards you with 40 times your stake if you manage to get 5 on a payline.

The Raptor wild symbol only shows up on the 3 central reels (reel 2, 3 and 4) in the main game – when they appear, they will expand to take over the whole reel to guarantee you a winning combo. If your luck is in, you can get 3 fully wild reels!

The monocle-wearing hunter is the scatter symbol and 3 or more anywhere in view will give you access to the game’s 4 bonus features. The more scatters you get, the more you can power up your chosen feature! You can choose from the following:

The Hot Shot Hunter Bonus feature allows you to shoot down dinosaurs that move across the screen. Every successful hit will give you cash prizes of up to 10 times your bet. Flying dinosaurs reward you with up to 50 times your bet with brown dinosaurs giving you up to 120 times your bet. Look out for the white dinosaurs as they can give you up to 180 times your bet.

The Multiplier Free Games feature rewards you with 10, 15 or 30 free spins (depending on how scatters you got). You can retrigger the feature giving you up to 60 free spins in total. All winning combinations come with a 3x multiplier and this is the high variance option.

Carnivore Free Games feature also gives you 10, 15 or 40 free spins with the feature being retriggerable to give you up to 60 free spins. On the reels, only high win symbols (the triceratops skull and 4 dinosaurs mentioned above) appear on the reels to give you better winning combinations. This is the medium variance option.

Lastly there’s the Raptor Free Games feature where you will get 16, 24 or 40 free spins. You can also retrigger the feature giving you up to 80 free spins in total. This feature is all about stacked expanding wilds meaning wilds will expand to take over the whole reel when they appear. This is another medium variance option.

Jurassic Island is a simple game with plenty to offer features wise – I will always go for the high variance option but I found the Raptor Free Games feature with stacked expanding wilds to be the most lucrative. Saying that, Hot Shot Hunter Bonus feature is pretty good if you manage to get a white dinosaur! If you like the pre-historic theme, Microgaming’s Jurassic Park and Playtech’s The Flintstones are recommended.
