This is a tool for helping with codewords. Codewords are puzzles where a crossword-like grid has numbers in each cell where a number represents a particular character. The idea is to work out which number maps to which letter of the alphabet.

Enter either a single character or a number in the range 1 to 27 for the number representing an unknown letter in each input box. Leave the remainder blank.

For example, '1', '2', 'w', '2' to search for a four-letter word where the third letter is w, the first character is different to the other letters and the same letter is repeated in the 2nd and 4th character positions.
