One phone, a whole team: how to share a city detective game

One person may hold the phone, but everyone can help solve the case. Here is a practical way to share reading, observation and decisions on a self-guided detective walk.

At City Mystery Trail, one smartphone can guide your team through a city detective game. You do not need a separate screen for every player. The useful question is how to make the person holding the phone a reader and coordinator, while everyone gets a chance to notice details and contribute ideas.

Choose the case together before you start

Compare the actual edition before choosing your game. Family and Group are separate cases, so check the age guidance, team size, walking distance where listed, and expected duration on the city page. Also agree on a game language that everyone understands. The language you select for playing matters more than the language someone happens to use while browsing the website.

Give the phone holder a small, clear job

The phone holder reads the story and the current instructions aloud. Before anyone enters an answer, let the others hear the question and the available choices. Keep the screen visible when a picture or a detail needs discussion. You can pass the same device to another reader when you stop safely; there is no need to turn the walk into a race for control of the screen.

Try three roles, then swap them

  • Reader: shares the instructions, including any condition that could change the answer.
  • Observer: looks for the relevant real-world detail, without rushing ahead or entering restricted areas.
  • Summariser: asks what the group actually saw and checks whether the proposed answer fits.

With two players, combine observation and summarising. With a larger team, invite more than one observation before deciding. For a family, let a child describe what they noticed before an adult supplies an interpretation. These are optional ways of organising your group, not extra rules required by the game.

Stop walking before reading or discussing

Move out of the flow of pedestrians before reading a longer passage. Keep crossings and navigation separate from puzzle discussion. The phone holder should not have to look down at instructions while the rest of the team moves ahead. If someone wants a break, use that moment to recap the case and agree on the next step.

Use help when it keeps the group involved

Before taking a hint, ask whether everyone heard the whole question. Then use the available help step by step if you need it. A hint is a way to continue enjoying the investigation together. If a location cannot be used, follow the help offered by your edition instead of guessing a new route or trying to get around a barrier.

A short checklist for the shared phone

  • Charge it before leaving and consider a power bank for a longer outing.
  • Check your mobile internet: answer checks require an online connection.
  • Open and read the starting instructions for the edition you selected.
  • Agree on the game language and who will read first.
  • Check the current availability; an edition marked as a pilot is still being tested.

A browser-based game does not require an app installation, but that does not make every part available offline. Prepare the device, then let the city and the conversation take most of your attention. For the next step, compare the available cases and choose the edition that fits your group.
