Legend has it that the famous pirate One-Eye lived in the city for a short time in 1516. One-Eye was a very private person, but one evening in a pub, he drunkenly told of an enormous pirate treasure consisting of thousands of gold pieces that were hidden somewhere on an island. In the town, he said, he had left clues as to where the treasure was to be found. Shortly afterwards he died and with him the secret. He did leave behind an old mysterious chest with a strange kind of riddle, with which the chest can be opened. To date, no one has been able to open the chest and find the treasure. Can you find out on which island the treasure is hidden and where it is buried exactly? It is important to go through the red pointers in order. So you start at pointer 1, then pointer 2, and so on.

While playing, you can also pause the app, for instance to go and have a drink somewhere. Although we do everything we can to keep all the points up to date, it can occasionally happen that a point has disappeared. If this is the case, we would like to hear from you and you will receive a nice discount on playing the next game.
