Online treasure hunt

Create an online treasure hunt that ends with a locked surprise

Use ChronoBoxes to turn a message into the final reward of a digital treasure hunt. Create several keys, write clues for each one and let players unlock the final message after solving them all.

Why this format works

The strongest treasure hunts alternate between easy progress and one or two memorable challenges. Digital clues can point to a room, a photo, a book, a map pin or an answer hidden in a shared memory.

ChronoBoxes separates the moment of creation from the moment of discovery. The recipient gets a private link, sees the waiting experience and opens the content when the configured date and any optional gate conditions are met.

Ideas you can use

Hide one key behind a QR code in a physical location.
Use a photo crop as a clue to a place or object.
Let each solved key reveal where the next clue is stored.
Finish with a message, invitation, gift location or surprise announcement.
Keep the number of steps proportional to the occasion; three to five is often enough.

How to create this ChronoBox

Write the core message first. Decide what the recipient should remember, discover or feel before adding effects.
Choose a date that has context. Timing should connect to the birthday, anniversary, project, trip or milestone.
Add gates only when they improve the experience. A secret question or location is optional.
Add media only if it adds meaning. You can include up to 6 photos and 1 video for free; boxes with uploaded media can open up to 6 months after creation.
Share the private link. Treat it as private information and send it only to the intended recipient or participants.

A concrete example

“KEY 3 is where we took the photo you still use as your lock screen.”

Use the example as a structure, not as copy. The more specific the message is to the people and moment involved, the more valuable it becomes when it opens.

What is included for free?

ChronoBoxes has no paid tier. Text-only boxes keep encrypted content inside the private link. If you add photos or video, those files use temporary server storage so they can be revealed later.

Text-only · FreeMessage, opening date and optional gates. Encrypted content travels in the private link.

Photos + video · FreeUp to 6 photos + 1 video. No checkout. Normal ChronoBoxes can open up to 6 months from creation.

What to avoid

Do not use ChronoBoxes as your only long-term archive; keep independent backups of important media.
Do not publish private capsule links on public pages or social feeds if the content is personal.
Do not make questions or location gates so difficult that they block the intended recipient.
