Ratty, the evil arch-villain, is trying to take over the world. Where is he? Can you crack the secret codes and find Ratty?

Game developed by Cambridge English Online


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!

Hi LadyYellowTrumpet,


We've checked the game and it seems to work OK. Try using a different browser. Can you ask an adult to help you?
