About this puzzle
Crack the code to find the answer to each riddle. Every letter of the alphabet has a number; children use the key to turn the numbers under each blank back into letters. Choose the simple code (A = 1, B = 2…) or a mixed-up code that changes with every sheet. A fun way to practise letter order, careful reading and spelling.
Tips for parents and teachers
- Decode the letters that appear most often first.
- Read the riddle aloud and guess before decoding: then check if you were right.
- Children can write their own secret messages for a friend using the same key.
