Pick a route, walk to each real stop, and solve the puzzle there with friends or family.



Work out a real landmark from the story, then hold the phone flat and turn until you face it. No arrow, no map pin, no hot or cold.
You get 3 tries, then the app shows you where it was.


Each route is 2 to 4 km, about 1 to 2 hours, with 6 or 7 outdoor stops you can visit at no cost.
Other cities are not in the app yet.
Every route can be played from home. The compass puzzle becomes a map you turn by hand.
You earn a different stamp for it, so a walked stamp still means you were there.



Each stop gives you a piece of the letter, and one last question at the end.
Mogu is a made-up mole. The places and the history are real.
Your location stays on your iPhone.
Two routes, Tokyo Asakusa and Seoul Bukchon, are included. All Routes is an in-app purchase that unlocks the others, with Family Sharing.
