One person does not need to write a script, assign roles, or prepare an answer key for you to solve a murder mystery with friends in Stockholm. In Gamla stan, you can buy the Mobile version of the game and investigate the case together on site. The important thing for a good group activity is not who owns the phone, but that everyone gets to see the evidence and participate in the reasoning.

Gather the group before you open the royal case
Start at the Outer Courtyard at the castle and make sure everyone has arrived before you start reading. The fictional poisoning gives you a shared case, but you are not playing different characters with secret missions. Therefore, do not make one participant the sole game master. The person who arranged the purchase may be just as unaware of the solution as the rest of the group and still make sure you get going.
Avoid the group becoming a queue behind a screen
The passages in Gamla stan are a good reminder to choose a place for discussion. Stop where you can stand together without blocking others and turn the screen so that more than the phone holder can see it. Read out relevant passages and summarize what you actually know. Just because one person has finished reading does not mean the group has had time to form an opinion; wait for the others before moving on.
Finish by comparing your initial suspicions
When the case is finished, you can let everyone tell which piece of evidence made them change their theory. It is often more fun than appointing a winner afterwards. If you continue to a café or restaurant, you arrange it yourselves and choose according to the day's opening hours. If you want a longer Stockholm day, you can add other stops separately, without mixing them up with the mystery's clues.
Check codes and technology before the gathering
A purchased game provides its own code, a two-pack provides two, and a three-pack provides three separate activation codes. Choose according to how you want to divide yourselves and check the product information before purchase. Have access to email, a charged mobile phone, and the internet. The game opens in the web browser without an app. Do not assume that multiple codes create a synchronized team game; the suggestions for roles and shared theories here describe how you can collaborate yourselves.
Let the whole group have time to make a decision
Before you move on, everyone can briefly say what they think and which piece of evidence they lean on. Take a clue if the discussion is at a standstill and avoid anyone opening the answer key for the rest prematurely. You have seven days after the game period has started with a special confirmation and can pause during the period. Decide on the practicalities together so that a pause does not mean that some continue while others are still trying to read.

Frequently asked questions
Can we solve the murder mystery in Gamla stan directly on our phones?
Yes. Choose the Mobile version of The Mystery in Gamla stan. After purchase, you will receive an activation code and game link by email. The material opens in the web browser, but the game is played on location in Gamla stan in Stockholm.
Do we need to download an app or wait for a booklet?
No. The mobile version is played in the phone's web browser with an internet connection. No game booklet is sent by post. Make sure you have chosen the Mobile version, not the physical format, before completing the purchase.
Where does the mobile mystery in Gamla stan begin?
The starting point is Yttre Borggården at the Royal Palace in Stockholm. Check the current starting instructions in the game and then follow the map and clues. A standalone walk around the area is not the same as the mystery's route.
Does one of us need to be the game master or know the solution?
No. You investigate the case together according to the material. The person who arranges the purchase and gathering does not need to read the solution, play a role, or know the culprit in advance.
How do the two-packs and three-packs of the Mobile version work?
One purchased game provides its own activation code. A two-pack provides two separate codes, and a three-pack provides three. Decide on the quantity based on your setup, for example, if several smaller groups are going to conduct their own investigations. Multi-packs do not mean several different cases.
How can everyone participate when the material is on a mobile phone?
Make sure everyone gets to see the evidence, read important passages aloud, and take turns holding the phone and summarizing theories. Decide on your cooperation yourselves. This is a practical suggestion, not a promise of a synchronized multiplayer mode.
