How to play

Each round shows a pattern or a coded word. Your child works out the next number or the hidden word; the alphabet is there to help with the shifts. Five right answers finish a level.

Levels

  1. Level 1What comes next in a number pattern?
  2. Level 2Read a secret word with a picture key.
  3. Level 3Undo a shift cipher.

A tip for parents

Write each other a short message in the shift code and see who decodes it first.

Works on phones, tablets and computers, with nothing to install. No ads and no tracking.
