This is the V1 of this design I created. It allows you to customize 3 rings that assemble together to form a decoder ring.

I made it so you can choose what graphics appear on each ring, how large they are, rotate them, etc. I think I found all the bugs - but let me know if you find anything and I'm happy to fix!

HOW TO USE: I used this with a Riddle hunt - each piece hidden, with a riddle clue. Once the kids found all the pieces, they had to figure out how to assemble it, and use it to decode the secret message.

I will share more details and updates if there is interest!
