Walk & Solve is an interactive murder mystery where you explore real places, gather clues and try to uncover what really happened.
Played on your phone. Nothing to download.
How it works
All you need is a phone, comfortable shoes and a bit of curiosity.
Your phone shows where to go and how far you have left. When you arrive, GPS unlocks the crime scene.

At each location you look around in 360 degrees. There are pieces of evidence, documents and witnesses to question.
Compare what you found, work out who is lying and name the killer. Then you find out how it really happened.
Current case
Knivsta. 23:52.
Gunnar Hed was about to reveal a secret that had lain buried for centuries. Now he is dead.
His notes are missing. Four people have something to hide. And someone is lying about what happened at the station.

About us
Walk & Solve started as an idea at a dinner table: a real murder mystery, but out in town instead of around the kitchen table. Every case is built on places that really exist and on local history, but the people and the crimes are made up.
The evidence in the game is made so that every time and every detail adds up. You do not need to know any history beforehand. Everything you need is in the finds and the interviews.
Right now we are testing the cases in Knivsta, Uppsala and Västerås together with beta testers. The cases are written in Swedish first, and English versions follow. In Sweden we are called Mordpromenad.
Questions
Not yet. The first cases are written in Swedish, and English versions follow, starting with the towns where most people sign up. This page is in English so you can find out what the game is about.
Allow about two hours and 3–5 kilometres. You walk at your own pace and can take a break whenever you like. The game is saved, so you can carry on later the same day.
A team is 2–6 people. Everyone in the team can follow the case on their own phone, or you can gather around one. If there are more of you, split into several teams and compare scores.
No. Walk & Solve is played right in your phone’s browser through a link. It works on both iPhone and Android.
The Knivsta case suits players from about 12. It is exciting but not gory. Crime scenes are shown with chalk outlines and props, not injuries.
No. The cases are built on local history, but everything you need is in the finds and the interviews. If you get stuck, you can ask for a clue.
You play for free during the beta test. At launch it will be 99 SEK per team and case, and beta testers get 50 percent off for the first year.
Right now we are beta testing cases in Knivsta, Uppsala and Västerås. Stockholm and Sigtuna are on the wish list. Choose a town when you sign up, so we know where interest is greatest.
