QR code treasure hunt

A QR code treasure hunt where every clue needs a code

Scan a QR code, crack the code, get the next clue. Make each stop its own lock with its own QR code, and the hunt plays in the phone's browser: no app, no player account, and the answer is checked on our server rather than hidden in the page. Free for 3 stops.

How it works

1

Make one lock per stop

One short riddle, one answer, and a reveal that says where the next QR code is hidden. Start from the free template or from a blank lock.

2

Print the QR codes and hide them

Every lock has its own QR code and a printable A4 poster, on every plan. Tape the first one at the start, hide the others where the reveals send players, and test the loop on your own phone.

3

Let them scan, crack and move on

Players scan, type the code, and the lock opens on the next hiding place. The answer is checked on our server, so nobody finds it in the page source.

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.

Two ways to set it up

Both work on the free plan. The first puts a code at every stop; the second starts from a single QR code.

One lock per stop
Each stop is a separate lock with its own QR code taped there. Scan, crack, and the reveal names the next hiding place: the full scan, code, next clue loop. 3 stops on Free, up to 10 with an Event Pass.
The 3-step template
One lock in three steps: one QR code to start, the riddles play in order on one page, and each reveal says where to go next. Each step also has its own QR code, under Edit next to the step, if you want one at every stop.
Stop 1
📅 How many months have 28 days? Numeric code, two digits: 12. Reveal: next QR code under the doormat.
Stop 2
📖 I'm the only word spelled wrong in every dictionary. Written answer: wrong. Capitals and accents are ignored. Reveal: inside the fridge door.
Stop 3
🏃 You overtake the runner in 2nd place. What place are you in now? Numeric code, one digit: 2. Reveal: the treasure is behind the sofa cushion.
Hints
Each lock has its own hint, behind a button, for the team that gets stuck.
Changing a clue
The QR code points to the lock, not to what it says: edit a riddle or a hiding place after printing and every code keeps working.

Hunts to build this way

The same loop, scan, code, next clue, fits any place where people can walk from one hiding spot to the next.

A birthday hunt

Three stops around the house, the present behind the last one. Start from the free QR hunt template and rename the hiding places.

A classroom or playground

One QR code per corner of the room or the yard, one riddle per subject. The free classroom templates have riddles ready to copy.

Team building at the office

Teams scan their way from the coffee machine to the meeting room. Each phone keeps its own progress, so teams never see each other's answers.

A wedding

Guests scan a code on each table and the last lock gives the seating plan, the first dance or a message from the couple.

Google Forms or a lock: an honest comparison

Google Forms can do it

A short-answer question with response validation, one section per stop: when the answer matches the rule, the form moves on to the next section. Familiar, and already there if your school works with Google.

When a form is enough

If what you need is each player's answers collected in a spreadsheet, a form does that by design. Use it.

Where a lock differs

The answer is checked on our server and the page never contains it. Each stop can use a different format, among 15: a code, arrows, colours, a pattern, a melody, a real GPS position.

Made to be scanned

Every lock comes with a short link, a QR code and a printable A4 poster, and opens straight on the riddle on a phone.

Help when they are stuck

A hint per lock behind a button, and your own line for a wrong answer, written for that stop.

Longer hunts

More than 3 stops: the Event Pass, paid once, holds 10 locks of up to 10 steps. Pro is for the clock, the ranking, the printable QR pack and commercial use.

Simple, honest pricing

Free for a 3-stop hunt: 3 locks, each with its own QR code, or one lock of 3 steps. More stops: the Event Pass, $7.90 for 15 days or $9.90 for 30 days, paid once with no renewal, holds 10 locks of up to 10 steps. Pro adds the clock, the ranking, the printable QR pack and commercial use.

QR code treasure hunt questions

Do players need an app?

No. A QR code opens a web page in the phone's camera or browser, straight on the riddle. Nothing to install and no account for players: you sign up to publish, they never do.

Does each stop need its own QR code?

Only if you want a code waiting at every stop, which is the classic loop: make each stop its own lock, and every lock has its own QR code and A4 poster on every plan. With the 3-step template, one QR code is enough to start: the steps play in order on one page and each reveal says where to go next. Each step of a game also has its own QR code, under Edit next to the step. Pro's printable QR pack is different: one PDF whose every page carries the same game link.

Can I change a clue after printing?

Yes. The QR code points to the lock, not to its contents, so you can change a riddle, an answer or a hiding place at any time and every printed code keeps working.

What if players get stuck?

Each lock has its own hint, opened with a button, and your own message for a wrong answer. Attempts are unlimited on every plan, so a team can always try again.

Does it work offline?

No. Players need a connection at each stop, because the answer is checked on our server rather than in the phone. That is also why nobody can read it in the page source.

How many stops can I make for free?

3. The free plan holds 3 locks, single or multi-step, of up to 3 steps each, and they never expire: three stops with one lock each, or the 3-step template. For a longer hunt, the Event Pass holds 10 locks of up to 10 steps.

Is it better than a Google Forms escape room?

It is different. A form checks a short answer with a validation rule and moves to the next section; a lock checks the answer on our server, offers 15 formats and comes with a QR code per lock. If you need answers collected in a spreadsheet, a form is the right tool. More in escape room with Google Forms, or see the treasure hunt generator for longer trails.

More ways to reveal something

Scan, crack, next clue
