Let everyone meet Valdemar Hedin at the same time
The person who bought the game doesn't need to present the case like a lecture to the rest of the group. Meet at Hagakyrkan, read the introduction together, and immediately distinguish between what the story says and what you think yourselves. That way, no one will feel they've missed anything before the group has even started walking. This murder mystery is a collaborative investigation game, not a role-playing game where one friend has to act as the murderer.
Swap roles between Haga stops
Let one participant read, another report what an interrogation actually revealed, and a third keep track of your open questions. Switch after a while so that the same person isn't both the navigator and the decision-maker throughout the game. These roles are a suggestion for how to work together, not extra features you need to set up in the game. Make sure everyone gets to look at the evidence before you leave the location.
Plan the gathering, not the solution
Send the right meeting point to your friends and ask them to wear walking shoes and have a charged phone if they're bringing their own. You don't need to reveal the story in the group chat to prepare for the activity. Decide whether you want to have a fika before or after and check the opening hours of the café separately. If there are many of you, smaller investigation groups may be more social than everyone standing around the same screen; choose the number of game codes accordingly.
Check codes and technology before the gathering
A purchased game provides one code, a two-pack provides two, and a three-pack provides three separate activation codes. Choose based on how you want to split up and check the product information before purchasing. Make sure you have access to email, a charged 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 moving on, everyone can briefly say what they think and what evidence they are basing it on. Take a hint if the discussion stalls and avoid anyone opening the solution for the rest of the group prematurely. You have seven days after the game period has been started with a special confirmation, and you can pause during that period. Decide on the practicalities together so that a pause doesn't mean some people continue while others are still trying to read.

Frequently asked questions
Can we solve the murder mystery in Haga directly on our phones?
Yes. Choose the Mobile version of Mysteriet i Haga. After purchase, you will receive an activation code and game link via email. The material opens in the web browser, but the game is played on location in Haga in Gothenburg.
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 mail. Check that you have chosen the Mobile version, not the physical format, before completing the purchase.
Where does the mobile mystery in Haga begin?
The starting point is Hagakyrkan in Haga, Gothenburg. Check the current starting instructions in the game and then follow the map and clues. A standalone walk in 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 answer key, 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. Determine 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 collaboration yourselves. This is a practical suggestion, not a promise of a synchronized multiplayer mode.
