A real city and a fictional case
In the game's fictional story, King Karl III Vasa has been poisoned. You need to investigate what has happened, weigh the clues against each other, and find the culprit. It is a fictional murder mystery, not a depiction of a real royal assassination.
From the castle courtyard to your own investigation
The starting point is the Outer Castle Courtyard, not the subway station or a café of your choice in Gamla Stan. Open the starting instructions when you arrive and then let the game's map and tasks determine the way forward. It is easy to want to take a shortcut through an alleyway you already know, but a regular sightseeing tour does not replace the game route. Read the next task before moving on, and step aside when you need to compare a piece of evidence with what you see around you.
From purchase to the first task
Select the Mobile Version on the product page and complete the purchase. The activation code and game link will be sent by email. Open the link in your phone's web browser, enter the code, and follow the instructions. No app needs to be downloaded, and no booklet is sent by post. When you are ready, confirm the start of the game period; you will have seven days from that confirmation. Simply entering the code and opening My Games does not start the timer.
Keep the map, interrogations, and evidence close at hand
The mystery is divided into eight parts. Read the tasks, listen to the interrogations, and compare the evidence within the same game. The map helps you between locations, and you can use hints if you get stuck. Have a charged phone with an internet connection, and it is a good idea to bring an extra battery if your phone has already been used a lot during the day. The material is digital, but you will make your observations in the real environment.
Let the alleyways catch your attention
The phone is the tool, but you also need to look up. Decide that you will read while standing still and put the phone away when you cross a street or walk through a narrow passage. That way, you can both discover details instead of one person navigating while the other simply follows. Comfortable shoes, a charged battery, and an internet connection are more useful than trying to memorize Stockholm's history beforehand.
Choose a format in case you want to solve
The mobile version and the physical booklet contain the same story, locations, and puzzles. Choose the mobile version if you want to receive the material by email and avoid postal delivery. If you have already solved the same mystery, switching formats will not give you a new solution to discover. Always check the product's current information before buying, and choose a different case if you want a completely new investigation.
