What is a digital scavenger hunt?

A digital scavenger hunt is an event format where participants use their smartphone to scan a QR code (or check in another way) at different locations to Collect stamps. It is the digital version of the classic “punch a paper card at each booth” experience, and the best modern tools require no app at all — everything runs right in the web browser.

The mechanics make the most sense once you try them yourself, so the easiest place to start is a hands-on interactive demo, where you can experience exactly what a participant sees and taps.

How it differs from a paper stamp card

Comparison	Paper stamp card	Digital scavenger hunt
Setup cost	Stamps and card printing required	Free trial — low cost to start
How to take part	Get a physical stamp on site	Scan a QR code with your phone
Tracking & reporting	Counted by hand	Automatic, real-time totals
Fraud prevention	Difficult	Manage with GPS and time limits
Participation history	Lost if the card is lost	Saved automatically to the cloud
Staffing	Someone must stamp every time	Can run unattended
Multiple languages	Separate print run per language	Switch languages in the settings

The single biggest advantage of a digital scavenger hunt is that you don’t have to station a staff member at every checkpoint. You simply print a QR code and post it, and participants scan and progress on their own.

The 3 types of digital scavenger hunt

“Digital scavenger hunt” is an umbrella term — in practice it splits into three types depending on your goal. You can see how each one works on the features page.

Stamp Tour

The most orthodox format: participants travel around several designated spots and Collect a stamp at each one. It suits any “visit multiple points in sequence” plan — mall and shopping-district trails, gamified tourism routes, campus tours, and school events.

Point Challenge

A format where participants check in at the same spot multiple times to accumulate points. It is ideal for rewarding repeat visits and building loyalty, and works well for restaurant and retail campaigns.

Collection Card

A format that works as a digital version of a shop loyalty card. You give one stamp per visit, and once a set number is collected the participant earns a reward. Great for shared loyalty programs across a district and for turning first-timers into regulars.

It helps to think of the three types as different mechanisms for changing the behavior of your target participants. Browsing real demos makes it easy to picture which type fits which situation.

How it works: 9 check-in styles

The core mechanic is always “check in at a spot to Collect a stamp,” but there are actually 9 different check-in styles. You can mix and match them to fit the kind of event you’re running.

The 5 most popular styles

1. QR code (the most popular)

Print a QR code, post it at each checkpoint, and participants scan it with their phone. No dedicated app is needed and setup is simple — it runs entirely in the browser. You can see exactly how it behaves in this interactive demo.

2. GPS

A stamp is awarded automatically when a participant gets close to a specific location. Because it uses location data, it suits outdoor and walking-route events — perfect for natural attractions and open areas where you can’t physically post a QR code.

3. NFC tag

Participants hold their phone over an NFC tag to Collect a stamp. The interaction feels even more seamless than scanning a QR code, making it a good fit when you want a premium, tactile experience.

4. Keyword entry (mystery)

Participants type in a keyword displayed at the spot. This is effective for events with a mystery or puzzle-solving element, since the answer can only be found on site. See the related quiz scavenger hunt guide for ideas.

5. Multiple-choice quiz

A stamp is awarded when participants answer a quiz at the spot correctly. It suits educational events and any plan where people want to learn something while having fun — great for schools and museums.

4 advanced styles for richer experiences

6. Sliding puzzle: collect puzzle pieces at each spot to complete the picture.
7. Photo submission: take and submit a photo based on a given theme.
8. Receipt scan: AI automatically reads a purchase receipt and awards a stamp.
9. AR: use augmented reality to enjoy AR content at a spot.

For small to mid-sized events, the app-free QR code style has the lowest barrier and the highest participation rates. If you want to design a richer experience, combining several styles is a powerful option. You can review every style on the features page.

3 benefits for event organizers

1. It drives footfall and exploration

A digital scavenger hunt encourages participants to visit multiple checkpoints. Used at festivals, shopping districts, trade shows, malls, and school events, it gets visitors to walk the whole venue naturally.

Because participants think “let me visit just one more,” organizers consistently report that dwell time grows and more people drop into individual shops and booths. This is one of the most common outcomes teams see across corporate team-building events, retail campaigns, and tourism trails.

2. High-quality events at low cost

A paper stamp card means paying for card printing, buying stamps, and staffing each checkpoint.
With a digital scavenger hunt you simply print a QR code and post it. A free trial is available, so you can start with effectively zero upfront cost.

You can check what your event would cost in advance on the pricing page.

3. Real-time participation data

“Which checkpoint is most popular?”, “When are participants most active?”, “How many people reached the goal?” — data like this is visible in real time on the admin dashboard. Being able to feed those insights into your next event is a major advantage over paper.

How to create a scavenger hunt: 5 steps

Step 1: Choose a tool

First, pick a service for building your scavenger hunt. The three main things to look for are:

Is there a free way to try it? (for a small event, start on a free trial)
Is it app-free? (browser-only lowers the barrier for participants)
Can you generate QR codes yourself? (no outsourcing, fully self-serve)

You can review capabilities on the features page and costs on the pricing page.

Step 2: Set up the event and spots

In the admin dashboard, enter your event name, dates, and checkpoint (spot) details. For each spot you can set a name, description, and photo.

3 to 10 spots tends to strike the best balance for participation
Many tools let you customize the stamp artwork per spot
You can set goal conditions (e.g. collect all spots, or any 5)

Step 3: Generate and post the QR codes

A QR code is generated automatically for each spot. Download it as a PDF or image, print it, and post it on site.
Even just printing it on standard letter/A4 paper and laminating it works perfectly well.

Where to post them

POP signage next to the checkout
Panels at an exhibition booth
QR stands on tables
Outdoor pillars and signboards

Step 4: Tell participants

Before the event begins, announce the QR code and how to take part.
Ways to spread the word:

Print the entry QR code on flyers and posters
Announce it on social media (Instagram, X, messaging channels)
Place banners and signage at the venue entrance

Keeping the instruction as simple as “just scan it with your phone camera” is the key to boosting participation.

Step 5: Run it and review afterward

While the event is live, you can monitor participation in real time on the dashboard — no staff need to be stationed at the spots.
After the event, most tools let you export participation data as CSV so you can use it for next time.

Frequently asked questions

Q. What if a participant doesn’t have a smartphone?

Since taking part is just a matter of scanning a QR code, almost any smartphone works regardless of model. For people without a phone, you can run a hybrid event alongside traditional paper stamps.

Q. Can older or less tech-savvy people take part?

The action is as simple as “point your camera at the QR code,” so anyone comfortable with basic phone use can join. Placing one staff member at the entrance to help with the first scan reliably boosts participation. You can preview the participant experience in an interactive demo.

Q. Can I tell whether people actually visited a checkpoint?

Yes. The admin dashboard shows scan counts per spot in real time. Because you can see which spots are popular in the data, you can improve your layout next time.

Q. Can I prevent cheating?

To stop people sharing a photo of a QR code and scanning it remotely, these measures help:

Time limits (the same QR can’t be re-scanned within a set window)
Combining with GPS (you must be on site to scan)
Combining with keyword entry (mystery) or quizzes that can only be answered on site

Q. What size of event can it handle?

If you choose a service with no participant cap, it scales from tiny events of fewer than 10 people to festivals with thousands. A good approach is to confirm everything works on the free trial, then pay for the spots and days you need for the real thing.

Q. Can I use it for international visitors?

Some services support multiple display languages, making them well suited to scavenger hunts aimed at international tourists. Petanco supports English, Japanese, and Korean as standard.

Q. Should I ask participants to install an app?

If you want to maximize participation, we recommend going app-free. App installs cause people who feel it’s “too much hassle” to drop off, so a browser-only flow consistently earns higher participation.

Q. How long should the event run?

It depends on the scale and goal, but here are rough guides:

Single-day festivals and weekend events: 1–3 days
Month-long shopping-district campaigns: 14–30 days
Tourism board exploration campaigns: 1–6 months

For long-running events, a service with volume discounts improves cost efficiency. You can model the cost on the pricing page.

Q. Can I use it for school events?

Some services offer plans aimed at schools and education. Petanco offers options designed to be easy to adopt even on a limited budget — see the pricing page for details.

Summary: choose the format that fits your goal

Compared with a paper stamp card, a digital scavenger hunt has major advantages in three areas: cost, operational effort, and data.

To recap how to choose:

Pick the scavenger hunt type that matches your event (Stamp Tour for touring, Point Challenge for repeat visits, Collection Card for loyalty) → details on the features page
Pick the check-in style that fits your location and audience (QR code indoors, GPS outdoors, photo submission or AR for experiential events) → check each style with an interactive demo
Choose a service with transparent pricing, no feature gating, and an easy way to try it → compare on the pricing page

The safest approach is to try it on the free trial first, get a feel for it, then move into full operation.
