CONFIDENTIAL / CASE BRIEFING
The story starts here.
Step into the covert world of a citywide detective mystery, where your mission is to expose a powerful secret society that has manipulated leaders and shaped world events from the shadows for centuries.
A whistleblower has surfaced with explosive information, drawing you into a high-stakes game of deceit and discovery.
Your task: follow the clues, crack the codes, and stay one step ahead before their next grand scheme unfolds.
Will you be the one to unmask the society and reveal the truth?
Oh… and when you do, don’t forget to say thank you.
Is this for you?
Who it's for
This Gresham route starts at Point 1 and runs about 1.8 km past LBC, as you trail a whistleblower's clues and crack codes to expose a secret society. Friends who love escape rooms but prefer the open air will enjoy it, and so will couples after a puzzle-led outing. Pick something else if you want a live guide to question, or a shorter game than around 90 minutes of codebreaking.

A little clarity before you go
Frequently asked questions
Is this like an escape room in Gresham?
It uses the same ingredients as an escape room: clues, codes and a story to solve against the clock. The difference is that it is played outdoors on your phone as a self-guided walk, so there is no room to book and you can start whenever your group is ready.
How long does the detective game take and how far do we walk?
Plan on around 90 minutes, covering about 1.8 km on foot. The time depends on how quickly your group cracks the codes, and you can pause the game and continue later if you want a break along the way.
Is it suitable for kids?
The game is aimed at adults and families with teens who like puzzles and mystery stories. The plot involves a secret society, a whistleblower and code-breaking, so younger children may lose interest before the end of the roughly 90-minute walk.
Can we play as a group, and do we need to book a time?
Yes. One ticket covers your whole group, up to the number of devices stated, and there is no fixed time slot or guide to meet. You start whenever you like, play at your own pace and can pause and pick up again later.
Is the game played outdoors?
Yes, the whole mystery is played outside as a walk of about 1.8 km through the city, with the puzzles set in what you see around you. Check the weather and dress for it, since you will be on foot for around 90 minutes.
