I have planned and half set up a treasure trail, made up of riddles. It takes you to a few different pages and then gives you a phrase which you can answer with.
I've just done this cos its Easter and you go on Egg hunts on Easter, so I made this for fun.
Before I post the actual question I just want to check this sort of thing is allowed and on-topic. If it is then I will post it tomorrow. Stay tuned for it!
