Gift card riddle

Hide a gift card behind a riddle

Put a gift card code behind a riddle they solve on their phone. The answer is checked on our server, not hidden in the page, and the code is sent to their phone only once they get it right. Free, no app, a link or a QR code.

How it works

1

Write the riddle and the answer

One short riddle, one answer only they would know. A written answer ignores capitals and accents, and it has one valid answer, so keep it to one word.

2

Paste the code in the reveal

The gift card code as text, a photo of the card, or the link the shop sent you. Every reveal is free on every plan.

3

Send the link or print the QR code

Send the link to them alone, or print the QR code inside a card. Turn on unlock alerts to know the moment it is opened.

Designed down to the last detail

Style every pixel of the lock, and watch it open on film.

Nothing on the screen is fixed. Pick a theme, choose a filmed object that fidgets while the lock holds and opens on video, with sound, when the code is right, then a celebration for the moment it opens. Set the typeface and size, and end on your own reveal. Your players see exactly the screen you designed.

Colours

51 themes, and more in the builder. Each one paints the lock, its keys and its button.

Video animations

54 filmed objects that fidget while the lock holds and open on video, with sound, when the lock gives way.

Typeface and size

37 typefaces and 6 text sizes, from a phone in hand to a screen across the room.

Or your own two pictures

Upload a closed and an open picture: the parcel as wrapped, then what was inside. Included with the Event Pass and Pro.

Every theme, every filmed animation, your own pictures, the celebrations, typefaces and text sizes come with the Event Pass or Pro. A basic lock keeps the default theme.

Is it safe to put a real code in there?

An honest answer: much safer than a code hidden in a page, and still not a vault. Here is exactly what protects it, and what does not.

The answer
Never in the page. A written answer or a code is stored as a bcrypt hash and checked on our server.
The code
Sent to the phone only after a correct answer. Before that, it is not in the page, its source or anything the page downloads.
Guessing
Attempts are rate limited per IP and per lock, which slows down anyone trying answers by brute force. It does not stop someone who knows you from guessing a weak answer: pick one only they would know.
Search engines
Player pages are noindex: the lock does not show up in search results.
The hint
The hint is in the page before anyone solves it. Never put the code, or any part of it, in the hint.
The melody lock
Do not use the melody lock for a valuable code: a melody to repeat has to play in the browser, so its notes can be read. Use a written answer, a number or a pattern.
Who sees it
Anyone who has the link and solves the riddle sees the code. Send the link to the recipient only.
Knowing it was opened
Unlock alerts, by email or Telegram, on every plan, tell you when it is opened (one switch per lock, off by default). Pro adds an access code, single use and a cap on players.
Retailer terms
Some gift cards cannot be resold or transferred. Check the card's own terms.

Riddles only they can solve

One short question, a few seconds to answer, a small smile. The best answer is one a stranger could not guess.

The first pet

What was the name of the hamster that escaped twice? One word.

The first date

What did you order on our first date and never finish? One word.

The receipt

How much was the bill at the restaurant where we met? Four digits, on a numeric lock.

The nickname

What does Grandma call you that you pretend to hate? One word.

The classic with a trapnone

The rooster on the barn roof from the demo above. Easy for anyone, so keep it for a small gift.

Make the opening an event

Free, as it is

The default look, your riddle, a hint and the code behind it. A basic lock never expires.

A filmed gift box

With an Event Pass, a filmed object opens on video when the answer lands: a gift box, a chest, a safe.

A look and a celebration

Every theme, typeface and celebration, so the card looks like it came from you, not from a form.

Your own photos

Your own before and after pictures: the wrapped present, then what is inside.

Paid once

The Event Pass is $7.90 for 15 days or $9.90 for 30 days, one payment, no renewal.

A whole hunt

Several gift cards, one per stop, or a short trail that ends on the code: chain the locks.

Simple, honest pricing

Free to hide a gift card behind a riddle, with unlock alerts. The Event Pass dresses the opening; Pro adds an access code, single use and a cap on players.

Gift card riddle questions

Can they see the answer in the page source?

No. A written answer or a code is stored as a bcrypt hash and checked on our server, so it is not in the page. The gift card code is not in it either: it is sent to the phone only after a correct answer. The hint is in the page, so never put the code in the hint.

What if they guess?

They can try as often as they like, but attempts are rate limited per IP and per lock, which slows brute force down. A weak answer can still be guessed by someone who knows you, so pick one only the recipient would know.

Can I add a photo of the card?

Yes. The reveal can hold the code as text, a photo of the card, the shop's link, or several of those at once, on every plan, free included.

Do they need an app?

No. The link or the QR code opens a web page in their phone's browser. Nothing to install and no account on their side.

Is it free?

Yes. A basic lock with a riddle, a hint and the code behind it is free and never expires, with unlock alerts by email or Telegram. The Event Pass adds a theme, a filmed opening and a celebration. See also surprise gift reveal and the written answer lock.

Can I change the code after sending?

Yes. The link points to the lock, not to its contents: change the code, the riddle or the reveal at any time and the same link shows the new one.
