Frequently Asked Questions
What is a codeword grid?
A crossword without clues: each letter of the alphabet is shown as a number, the same number everywhere it appears, and you deduce the substitution.
Do all 26 letters appear?
Yes — every alphabetical letter makes at least one appearance in the grid, which is what makes frequency analysis a reliable way in.
