Write the English alphabet on a piece of paper, then write it backwards underneath so A = Z and B= Y. Now, write a message below in the code and we'll see if other children can crack the code.


Good luck code crackers!

the 1st one i know but they todld that it is wrong

i can't undersand it. when i write(ratty is in europe) it says that it's wrong. would you please help me ander stand it

Hi Green Grey2,

I just tried it too. Hmmm.... if you write the answer in capital letters only, it works. So write: RATTY IS IN EUROPE

Then you will get the next clue. I'm not sure why it has to be capital letters, I'll investigate.

Good luck, Miss Lucky Mouse (website editor)
