How to add fun with QR codes into the clue game type?

Previously we have written how to think out clues for a clue game and what kind of question activations can be used in it. In addition to these, you have an option to activate questions in the clue game with QR codes.

A QR code is a simplified square image, that opens up a content when you point the camera of your smart device  to it. In Loquiz, when you create a game, you can download QR codes for all the questions in pdf and print them out. You can use QR codes for other game types but the following option is about using them in the clue game.

A simple option is to print the QR codes out and hide them around the game area. So, players have multiple options to unlock a question- entering the clue code, scanning the  QR when they stumble upon it. If question has opened up by either, it can not be opened twice!
