Get Samsoe Trolls and hunt for trolls. See how many you can catch and whether you can get in the top 10 list. At the same time you catch Samsø's Trolls you come around and see the island. The trolls usually hide in exciting places and always tell a little story about where they are hiding. The trolls hide around the entire island and you can only catch them when you are very close. Ie you can't play the game unless you're on the island. ***** When you are 10 years old and lacking money for V-Bucks in Fortnite, you might be able to earn them by going to newspapers, beating the neighbor's lawn or begging them from the grandparents. However, Alexander got another idea - "How about making an app?" After all, when one's paternal grandfather is one who makes Apps, it was obvious to partner with him. So Samsø's Trolls are run by Alexander and the papa father runs strongly to keep up with the new ideas for the game :-)
