Advanced Verbal Reasoning: Codes with Two Rules and Mirror Codes
If CAT is coded DZU, the rule changes from letter to letter: +1, −1, +1. Fizz the fox shows how to find an alternating rule and wrap round the alphabet. Then crack a mirror code where A swaps with Z and B with Y (GOLD → TLOW), using the trick that mirror pairs add up to 27.

If CAT is written as DBU, what is DOG? Fizz the fox shows how to find the rule for each letter (+1) and apply it to a new word (EPH). Then crack a code where every letter moves back two (FROG → DPME), and learn that the alphabet wraps round from Z to A.

If PAN is 5 3 8 and TAP is 2 3 5, what is the code for NAP? Leo the lion matches each letter to its number, starting with the letters the words share, then builds the new code (8 3 5). Then work out MEG from LEG = 4 7 1 and GEM = 1 7 9.

If CAT is written ★▲● and TEA is written ●◆▲, how do you write EAT? Professor Hoot the owl matches the letters the words share (A and T) to the symbols the codes share, works out every letter, and writes EAT as ◆▲●. Then decode ●◆▲■ yourself.
