Most QR codes open a page nobody reads. A QR code that opens a challenge is a different object: it asks for thirty seconds of attention and gives something back for it. The code you download here points at a lock, and the lock points at whatever you decided is worth the effort.
Password
The magic word to open.
Start from what people get: a discount code, a link to an unlisted page, a downloadable file, a short video, a message. The reveal supports all of those, and several at once, which means the puzzle can be as small as the reward is real. A three-letter password in a shop window is enough when the code behind it is worth using.
Download the QR as a PNG and put it on a flyer, a window, a table tent, a slide or a pack insert. The link behind it stays yours to edit: change the offer, change the answer, change the end date, and the printed code keeps working. That is the difference between a campaign and a reprint.
Set an opening date so a launch code does nothing before its hour. Set an expiry so a seasonal offer closes itself. Cap the number of players, add a shared access code for a private list, or make it single use for a one-winner mechanic. Everything is enforced on the server, not in the page.
Sessions, attempts, success rate and completion tell you whether the puzzle was the right size. Too easy and everyone completes on the first attempt; too hard and you will see the abandonment. Both are useful before the next print run.
Playable examples you can copy in one click. Try one first, then make it yours.
A discount worth working for. Put the QR code in a shop window or on a flyer.

Scan-to-page is a leaflet. Scan-to-challenge is an experience. The second one gets remembered.
