Every year, I run an Easter egg hunt at work. It has teams and clues and everything! The teams each go round a loop of clues and then the final clue will take them to the last location, where their are bigger eggs, but only for the team who gets there first. I like to have something extra for this final clue to make it more complicated!
In previous years, I've had teams collect a letter at each location which they had to unscramble so it spelled out the final location; one year they collected a key at each location and then the final clue directed them to a locked box where they had to try all the keys to find the right one; and one year they collected a puzzle piece at each location and then put them together to form a picture of an egg with the last clue written on it.
However, I'm stumped about what to do for the final clue this year. I've tried googling Easter egg hunt clues but they all seem very simple and for children (as you would expect). Whatever I do, it needs to be in such a way that you can't figure out the final location until you've been to all twelve locations. With the "collect a letter" one, the letters were actually in a code which you needed to turn back into the original letters with a code breaker which you recieved at location 12.
So, oh wise people of Mumsnet, do you have any creative and cryptic ideas?
