Jurassic Park was one of the most popular movies of the 20th century and the slot has become an equal favourite with online casino players. The principal route to riches is via the Free Spins feature which is activated when 3 or more Amber Fossil symbols appear anywhere on the reels. There are 5 free spin features in all.
They are triggered randomly at first. Once you've activated the free spins 25 times or more, you can choose whatever feature you prefer. Twelve free spins are on offer in all five features, as well as a selection of other goodies. First is the Tyrannosaurus Rex feature - in addition to the dozen free spins, the T-Rex symbol stacks three-deep on the reels. Up to 5 reels can be stacked which can be very lucrative.
Next is the Velociraptor feature which comes with Split Wilds and Multiplier Wilds - these can boost winning paylines by four, five or six times your stake. If the Velociraptor appears on the reels, it will become stacked too. The Brachiosaurus feature comes next – a random number of the free spins are subject to a multiplier ranging from 2x to 6x your stake. The Brachiosaurus symbol is stacked too. You can also re-trigger more free spins in this round.
The Triceratops feature follows, offering running wilds, random stack nudges and yet more re-spins. One wild is added to each reel after each free spin. If your spin isn't a winner, any full stack of wilds will remain in place. Partial stacks will get a nudge from Triceratops to fill the reel with the remaining reels spun again.
Finally there's the Dilophosaurus feature which comes with winning wilds where random symbols become wild. If they're part of a winning combination, they become winning wilds and remain in place as long as they're part of a successful payline.
The other major feature to look out for is the T-Rex Alert Mode feature. Randomly activated, it will add extra wild symbols to the reels for the next six paid spins. It can end up creating 35 wilds which can lead to superb payouts.
Jurassic Park is a nicely balanced offering, sitting in the medium range on the variance scale. As you'd expect from a link-up between a top software developer and a Hollywood giant, the visuals in Jurassic Park are terrific. It features many of the characters from the movie but it's the dinosaurs who are the stars, all set nicely against a tropical jungle backdrop.
Dinosaurs may have been extinct for millions of years but the potential payouts they offer here are very much alive. The T-Rex Alert can produce something suitably mighty, as can the free spins. The top prize of up to 6,480 times your stake is anything but prehistoric. In terms of the free spins features, the most lucrative are the T-Rex and Triceratops. If you love film-inspired slots, you should try Scarface by NetEnt as well as Terminator 2 by Microgaming.
