The dinosaur with green hair is wild. It can land on reels two, three and four and will substitute for all the other symbols, except the scatter, to help and form winning combinations.
The Victorian explorer is the scatter symbol and key to the bonus features.
If you land three or more scatter symbols anywhere on the reels you will be given the choice of four bonus features. The Multiplier Free Spins give you 10, 15 or 30 free spins (depending how many scatters triggered the feature) during which all wins are tripled. The Carnivore Free Spins give you 10, 15 or 30 free spins during which only high value symbols are on the reels. The Raptor Free Spins give you 16, 24 or 40 free spins during which wild symbols are stacked and can expand. The Hot Shot Hunter option is a game in which you need to shoot the dinosaurs in exchange for cash prizes.
Jurassic Island offers a top payout of 1,000x for landing five of the green dinosaur symbols across a payline. The purple and blue dinosaurs can both payout up to 300x while the red dinosaur and the skull can both payout up to 150x.
