Count. Crack the codebook. Bring the bell's word home.
Count at each stop, decode the numbers with a codebook, and unscramble the letters.
Follow the shadow. Collect the letters. Name the man.
Eight words across Old City each surrender a letter. Unscramble them into a name.
Run the spy ring. Break the needlebook cipher.
Run a spy ring through occupied Philadelphia; a needlebook cipher hides the warning's destination.
Each game is a self-guided mystery played entirely on your phone — no app download required.
You will visit 7 to 10 real landmarks across Independence National Historical Park and Old City, solving a clue at each one.
Every answer is hidden in a permanent, free, publicly visible feature — an inscription, a statue, a marker, a memorial wall. You have to be there to solve it.
Games cover roughly 1 to 2 miles on foot and take 45 minutes to 2 hours depending on difficulty.
Perfect for families, couples, history enthusiasts, and anyone who wants to see Old City with new eyes.
Each game link is valid for 7 days from the time of purchase — plenty of time for a full visit.
A couple of stops are daytime churchyard or courtyard features — the Deep Dive game is best played in daylight.
