Operation Cloud Gate
Millennium Park is full of things most visitors walk right past. Someone left a message here, one word at a time, in steel and stone. Four objectives, about a third of a mile on foot, all inside the park. No streets to cross, kid-sized finds, and a giant playground next door when you finish. Find the words.
Where you'll walk
Start at the Bean and finish at Wrigley Square, all inside Millennium Park. About a third of a mile on park paths with no streets to cross, and the stops in between revealed as you play.
Where the mission takes you
Real places, all inside Millennium Park: Cloud Gate (the Bean), the giant faces of Crown Fountain, the building the Bean sits on, and the white columns of Wrigley Square.




What to expect
A short walk around Millennium Park with puzzles on its landmarks. Every puzzle is outdoors and free: no tickets or lines.
Start at the Bean
Begin at Cloud Gate in Millennium Park. The team plays on one phone, in its web browser.
Walk and solve
Each objective asks you to find something real: a count, a name, a word carved in stone, a building hiding under the Bean. Every puzzle has three free hints, and the third is the answer.
Calls from Operations Center
After each stop, Operations Center calls with what you found and your next objective. Every message also appears on screen.
A finale worth the walk
Collect the words along the way. At Wrigley Square they come together. Then cross the BP Bridge to the giant playground at Maggie Daley Park.
No streets to cross: every stop is inside the park. The stone around Crown Fountain gets wet and slippery.
One phone runs a team of about 5. Add phones for $5 if you'd like to split up.

What if we lose signal?
Open your link once with signal, before you head out. After that the mission keeps working if service drops between stops.
Do we need an app or an account?
No. It runs in the phone's web browser. Nothing to install, nothing to sign up for.
How many phones do we need?
One phone runs a team of about 5. Add phones for $5 each if you'd like to split up; each phone keeps its own progress. Bringing a school or youth group? See Groups.
How is this different from Operation Four Stars?
Four Stars is the full Chicago mission: about a mile, from the Bean up Michigan Avenue to Tribune Tower. Cloud Gate stays inside Millennium Park, about a third of a mile with no streets to cross, sized for families with younger kids.
Is it safe for kids?
It's a short walk on park paths with no streets to cross. You're responsible for your group's safety: supervise minors, especially on the wet stone at Crown Fountain. Full details in the terms.
