The game can be played without supervision via an App on a smartphone at any time (the condition is that you play it on Terschelling itself (West-Terschelling))! It is a very nice way to get acquainted with the history, stories and sights of Terschelling and West Terschelling in particular. During the game, the clock runs backwards from 2.5 hours. Just like in an escape room, the mission is over when the time runs out. The secret location then remains a mystery. You carry out this mission on West Terschelling (start is at the VVV Terschelling). The code is valid once. Make sure you have a sufficiently charged smartphone. Minimum age is 10 years. Suitable for 2 to 5 people. This mission is in German.
