A puzzle box in a link

Lock a secret. Dare them to open it.

Write a secret. The AI turns your clue into a riddle. Share the link. Five tries, two hints, one right answer.

Only the right answer opens a box. We can't: the key is made from the answer in your browser.

Riddle5 attempts · 2 hints

I have keys but open no locks. I have space but no room. You can enter, but you can't go in. What am I?

The box wants: a thing

A hint costs an attempt. Wrong answers wait longer each time: 1, 2, 4, 8, 16 seconds.

Only the right answer opens a box. We can't: the key is made from the answer in your browser.

Up to about 2,000 characters without an account, 16,000 with a passkey.

RiddleOne answer opens it. Not even we can.
GameA judge reads a free answer. A game, not a lock.
On a dateNo riddle. Only the link opens it, on the day.

Games hold up to 1 KB of text and close 7 days after they open.

Standard: your answer however it's phrased. The AI tidies each attempt to one plain value ("in Paris, I think" reads as "paris"), and only your answer and the others you tick open the box. Strict: exactly your answer, ignoring capitals, punctuation and "the"; no AI reads attempts. Relaxed: Standard, plus looser descriptions you tick. Each step lets a few more answers in.

Leave it empty and it opens when they solve it. With a date, even the right answer waits: it opens at midnight at the start of that day, in your time zone.

Spaces and capitals don't matter. The riddle is written for this answer; the answer itself is never shown or stored in the clear.

5 attempts, 2 hints, opens once, expires 7 days after it opens (30 with a passkey). Change any of it after.

How it works

1

Write the secret

A note, a confession, a gift code, the surprise. A few thousand characters.

2

Describe the puzzle

One sentence. The AI writes the riddle and two hints, and never sees the secret.

Share the link

Only the right answer opens it. Watch the attempts, revoke it, or let it expire.
