A scavenger hunt is one of the best uses of a QR code. Each clue hides behind a scan, so players cannot peek ahead, and the organizer does not need to guard a stack of paper slips. The same idea works for a birthday party, a classroom review, a team building afternoon, a museum visit or a neighborhood event. What makes a hunt succeed is not fancy technology but a few practical choices: how to write the clues, how to print codes that scan outdoors and how to test the route. This guide walks through all of it and shows how to make every code for free with a QR code generator in your browser.

Make Your Clue Codes, FreeHow a QR Code Hunt Works
The idea is simple. You hide printed QR codes in different places. Each code holds a clue, either as plain text or as a link to a page. Players scan a code, read the clue, solve it and walk to the next place, where they find the next code. The last code reveals the prize location or a final message.
Because the clue is inside the code, there is no way to see it without scanning, and you can change the text of a clue in your files without redoing the whole game.
Choose the Type of Hunt
- Party or family hunt: short riddles with codes hidden around a house or garden.
- Classroom review: each code holds a question, and the answer points to the next location.
- Team building: teams race along a route and each code unlocks a task.
- Museum, park or town trail: codes at points of interest, with facts and the next direction.
- Escape room style: codes with puzzle pieces that only make sense when combined.
Decide who will play, how long it should take and how many codes you need. Five to ten codes suit a party. A classroom or event trail can have more, as long as the route is clear.
Write Good Clues
- Write each clue so it leads to a place that really has a spot for a code.
- Keep clues short. People read them on a phone screen, often outside in bright light.
- Match the difficulty to the players. For young children, use a picture or a simple rhyme. For adults, use a puzzle or a question.
- Number the codes only on your own master list, not on the cards, so players cannot guess the order.
- Make the last clue satisfying, such as the location of a prize or a short congratulation message.
A plain text clue is the simplest: the code holds the words and a phone shows them when scanned, without needing internet. A link to a page lets you add pictures or a video, but it needs a connection and a working page.
Make the QR Codes Step by Step
- Write all your clues in a list and number them for yourself.
- Open the QR Code Generator. It accepts plain text as well as links, and the preview updates as you type.
- Paste the first clue, choose a medium error correction level and a size of at least 512 pixels, and download the PNG.
- Repeat for each clue. Name the files with your numbers, such as clue-01.png, so you can print them in order.
- For a bigger hunt, how to generate multiple QR codes at once shows how to save time.
- If you want colors for different teams, use the Custom QR Code Generator, but keep high contrast so every code scans.
The tool runs in your browser, with no signup and no watermark, so you can make as many codes as the game needs.
Print Codes That Scan in the Real World
Hunts often happen outdoors, in a garden, a park or a hallway, where light and wind are not friendly to paper.
- Print each code at least 5 centimeters wide. Make it larger if players will scan from a distance. See QR code size for printing.
- Use black on white and keep a clear margin around the code.
- Laminate the cards or use plastic sleeves for outdoor use, and choose a matte finish to avoid glare.
- Tape or clip the card flat. A curled corner or a wrinkle can stop a scan.
- Add a short label such as Clue 3 for your own helpers, or a symbol for each team, so nothing gets mixed up.
If you plan to tape codes to curved objects, read QR codes on mugs, bottles and curved surfaces first.
Test the Route Before the Game
Walk the route yourself with a phone, scanning every code in order.
- Scan each code from the distance and height of a real player, including a child if kids will play.
- Check the clue text on the screen. Look for typos and for text that is cut off.
- Confirm that each clue really leads to the next hiding place.
- Check phone signal at every spot if any code links to a web page. Use plain text clues if the signal is weak.
- Ask a friend to try it with a different phone. Camera quality varies.
The checklist in why won't my QR code scan helps when something refuses to scan.
Run the Game Smoothly
- Give each team a different order of clues so they do not all arrive at the same spot at once.
- Tell players that any phone camera app can scan the code, and that they do not need to install anything.
- Keep a spare printout of every clue for helpers, in case a code is lost or a phone fails.
- Remind players to put the cards back or leave them in place so other teams can use them.
- Collect all codes at the end so nobody scans old ones by accident.
Frequently Asked Questions
Can a QR code hold a plain text clue?
Yes. The generator accepts plain text, and a phone shows it on scanning without needing a web page. A link is better when you want pictures or a video.
How many QR codes do I need for a scavenger hunt?
Five to ten suit a party or a family game. A classroom or event trail can use more, as long as the route is clear and the game stays fun.
How big should the printed clue cards be?
At least 5 centimeters wide for the code itself, and larger if players will scan from farther away. Keep a clear margin and use matte, flat cards.
Do players need an app to scan?
No. Most current phones scan QR codes with the regular camera app, so players only need to point the camera at the code.
