types of code backwards

This is a simple code to solve – just read the words backwards!  Even though it seems simple once you know the secret, it can be a hard one to figure out when you don’t.

2.  Half-Reversed Alphabet

Write out the letters from A to M then write the letters from N to Z directly below them.

3.  Block Cipher

Write the message in a rectangular block, one row at a time (we used 5 letters in each row).  Then writes down the letters as they appear in the columns.

4.  Read Every Second Letter

Read every second letter starting at the first letter, and when you finish, start again on the letters you missed.

5.  PigPen

The PigPen code is easier than it looks and is my children’s favorite.  First, draw out the two grids below and fill in the letters:


Each letter is represented by the lines around it (or pigpen).
