===Objectives===
===Group Size===
* [[Category:Medium]][[:Category:Medium| Medium]]
* [[Category:Large]] [[:Category:Large| Large]]
===Materials===
* Cell phones equipped to read QR codes (e.g. iPhones, Android-powered devices like the HTC Dream/T-Mobile G1, and the Palm Pre, many Samsung and Sony-Ericsson models, and most Nokia phones).
* paper & tape (or stickers to print the QR codes onto)
===Set Up===
This activity requires a bit of prep
* Decide on your clues - clues can be a mix of text riddles and websites, or email addresses with auto reponses.
* Create QR codes with clues embedded using a generator like this [http://zxing.appspot.com/generator/ QR Code Generator from the ZXing Project]
* Post the clues around your office, school, or all over your neighborhood or city
===Directions===
Divide the group into teams. Make sure each team has an internet equipped phone that can correctly scan a test QR code (and it's a good idea for each group to have a backup as well). Send them out to scan the codes and solve the puzzles.
===Debrief===
===Alternatives===
You can add in clues that require teams to email their solution to a puzzle to a certain email address (and then set up an auto response to provide the next clue).
