AI-generated illustrationCITY EXPLORING WITH A MYSTERY TO SHARE
City Mystery Trail is a self-guided city detective game: your phone brings the story, the city gives you something to discover. Observe real places, collect clues and solve a fictional case together. Turn a family outing or a walk with friends into a shared adventure, at your own pace.
01 / How to play
There is no on-site host and no app to install. Stay together as a team and follow the game in your phone's browser.
Explore the Family and Group editions listed for your city. Each game page shows team size, age guidance, estimated duration, walking distance and current availability. The two editions are independent stories, rather than difficulty settings for the same case.
A purchased team ticket covers one team and the selected game. Choose English, German or Hungarian, read the starting instructions and head to the specified starting point. Pilot games may have separate access conditions.
At each stop, investigate your surroundings as well as the story on your screen. Read aloud, compare what everyone has spotted and decide together. Written directions and map navigation help you reach the next location.
Use your collected clues to reach the final conclusion. If you get stuck, reveal the progressive hints a little at a time. You can take a break along the way and continue within your game's access window.
02 / Families & groups
Choose around your team's ages, appetite for walking and available time. Both formats bring you together to observe the city and discuss what the clues mean.
A shorter detective walk with a part for children and adults alike. Take turns reading, spotting details and leading the team. Couples and small groups of friends can also choose this format for a lighter city adventure.
A longer, independent story for friends and small teams. Share the jobs: one person navigates, another reads the case and the others keep track of the evidence. The emphasis is on connecting observations and reaching a conclusion together.
Durations are estimates: breaks and your team's pace make a difference. Check the selected game page for exact team limits, age guidance, distance and availability. Larger parties should plan several teams within those limits.
03 / Before you go
A little preparation lets you spend your time on the shared adventure once you arrive.
One smartphone is enough for your team to play together. Open your access before setting off and have an internet connection available for loading the game and maps. A power bank can help on a longer walk.
This is an outdoor walk. Check the forecast, plan breaks and postpone in unsafe weather. Step out of the flow of pedestrians before reading from your phone.
Check the game's distance and age guidance. If you are bringing a pushchair or have mobility requirements, clarify the route details before setting off; conditions vary between city routes.
Read aloud, take turns spotting details and look up from the phone. You can prepare the PDF included with your access in advance. Printing is optional; read the separate instructions for playing on paper.
04 / Cities
Choose a destination or see a familiar city with fresh eyes. Each city page lets you compare editions and see which games are available to buy, open for testing or not yet available.
