I seem to be having trouble with my Jurassic challenge for Isla Tacano. My facility rating's good and I'm almost at 4 stars but I'm concerned about my dino rating. I know it needs more points in genetics and paleobotany but am trying to save up my money you know. Did you finish Sanctuary so fast because of all the carnivores of the same species?I finally found some time to complete Jurassic Difficulty Sanctuary. I took me 4 hours 30 minutes to achieve 5 star rating.

In order to do that you need to have 22 species that are worth 12500 points. This time I took a photo of map of the park that I have built. As I mentioned before, all of the buildings need to be situated nearby the Arrival Point (I used only 1 Viewing Gallery, 3 Hotels, 3 Gift Shops and 3 Fast Food). Other buildings are: Storm Defence Station, Emergency Shelter, 3 Small Power Station, 2 Medium Power Station, hatcheries and the operational buildings. As always 1 hatchery is connected to 4 pens. I ended up having 135 Troodons! You may be wondering why I have built these small enclosures away from the main park in the upper right corner of the photo. These ”boxes” are the lures for twisters. I save the game always when the storm begins. When the hurricane spawns in the place that is not convinient for me at all I just reload the game and wait for it to spawn at the other corner of the map. This allows me to focus on playing during the tornado. There’s also a bug – if you save the game before the light storm and then reload the save, the storm will not cause any damage to your buildings and it will last shorter. I hope that this has been helpful. I apologise for the quality of the photos.
